Failure to follow these conditions may result in injury.Maximum static magnetic field of 100 Gauss (0.01mT)Device remains outside the scanner borePreparation protocols described in the Warnings section textd Use in the MR Environment must be followed before MR procedureImage Artifacts:When the GENOSYL DS is battery powered, no image artifacts are expected. When powered using wall outlet, minor noise is expected.Throughout this Operators Manual, warning, cautions, and notes will be displayed in the following manner.WARNINGThe warning box will alert the user to possible injury, death, or serious adverse reactions associated with the use or misuse of the device.CAUTIONThe caution box will alert the user about proper use of the equipment and any conditions that could result in equipment damage or failure. The user should read and adhere to all warnings and cautions.NOTEThe note box provides information, clarification, or supplemental information to assist and educate the user on the use of the equipment.A complete list of Warnings and Cautions for the GENOSYL DS are shown below. Where appropriate, some of these will also be shown throughout this manual.WARNINGSPlease consult the package insert for complete list of contraindications.AlarmsALWAYS acknowledge and follow information provided from alarms. An alarm indicates an abnormal condition, and ignoring alarms can result in possible injury, death, or serious adverse reactions.ALWAYS use clinical judgement when setting upper or lower alarm limits. Failure to do so could result in possible injury or death.ConsolesALWAYS have second Console present and properly connected when Dosing Console is connected to the patient. If the Dosing Console malfunctions, switch to the Back-up Console. If the Back-up Console is not available or properly connected, this may result in patient injury or death.DO NOT clean the GENOSYL DS with the power connected and the System turned ON, as this may lead to injury (e.g., shock). Unplug AC/DC power supply external to the System prior to cleaning.NEVER modify the equipment. Modifications of the equipment may result in malfunction, which may result in fire, shock, injury, or death.NEVER turn the rear power switch OFF until the System has gone through controlled shutdown or instructed by VERO Technical Support. Turning the rear power switch OFF prematurely (e.g., while it is still in use) will immediately shut down the device. This may result in interruption in NO delivery to the patient, which may cause injury or death.CassetteDO NOT use the Cassette if the Cassette State Window is not blue. Cassette State Window that is any color other than blue may affect the Cassettes ability to provide the correct NO dosage to the patient, which may cause injury or death.DO NOT use Cassette that is beyond its expiration date. Using an expired Cassette may affect the Cassettes ability to provide the correct NO dosage to the patient, which may cause injury or death.MAKE SURE the System stabilizes to the prescribed concentration (ppm) of NO prior to leaving the Console unattended. Failure to do so could result in under delivery of the target NO, leading to injury or harm.ALWAYS replace Cassette once depleted. depleted Cassette will interrupt patient dosing and can lead to under dosing and/or injury to the patient.ALWAYS follow Cassette inspection instructions prior to Cassette insertion. Not inspecting the Cassette prior to insertion may lead to using faulty Cassette, resulting in injury.Use in the MR EnvironmentThe GENOSYL DS is classified as MR Conditional with MR scanners of 1.5 or 3.0 Tesla strength ONLY in areas where the field strength is less than 100 gauss.ALWAYS operate at fringe field of less than 100 gauss. This device contains ferromagnetic components and may experience strong attraction close to the magnet.DO NOT exceed 100 gauss; System operation may be impacted. Confirm Cart caster lock function. Optionally connect tether.NEVER use the GENOSYL DS in the MR scanner room without gauss alarms installed.ALWAYS verify at least one gauss alarm is functioning properly prior to use in the MR environment.DO NOT use the GENOSYL DS in the MR environment if neither gauss alarm is functional.ALWAYS move System away from the MR scanner if the gauss alarm sounds. The gauss alarm will sound if the System is too close to the MR scanner. Move System away from the MR scanner until the gauss alarm stops sounding.ALWAYS verify that the GENOSYL DS Cart casters are locked after positioning the System in the MR scanner room.ALWAYS verify that the GENOSYL DS is securely attached to the Cart.ALWAYS arrange power cord, MR patient gas sample line, and NO delivery line to avoid entanglement, strangulation and/or trip hazard.DO NOT use the GENOSYL DS in the MR environment if the Cart moves when the brake caster locks are engaged.NEVER perform NO or NO2 calibration within the MR scanner room. Calibration equipment is potential projectile hazard.ConnectionsALWAYS follow pre-use setup instructions for the routing and connections of tubing to avoid patient strangulation.MAKE SURE the System has all tubing connected as described in the instructions. Not connecting all tubing may result in inaccurate dosage and harm the patient.NEVER touch the electrical connectors of the System or its accessories, and the patient simultaneously. If the user touches another device with ground-fault failure and simultaneously touches the GENOSYL DS, this can result in injury (e.g., shock) should grounding failure be present.BatteryONLY properly trained personnel should replace the battery. Incorrectly replacing the battery may result in hazard such as excessive temperatures, fire, or explosion.MAKE SURE the GENOSYL DS is connected to AC wall power to charge the battery minimum of once every months to maintain minimum battery charge. Failure to recharge the Console battery for extended timeframes may result in full discharge of the battery. If Battery Error message occurs during startup of the System, contact Technical Support at 877-337-4118 for assistance.UserONLY intended users who are experienced in the use of this System should use this device. US federal law restricts device use to licensed medical professionals. If device is used by unintended users, device can be misused and lead to injury or death.Alternative Means of VentilationALWAYS ensure that the manual flow displayed on the Console matches the flow set into the resuscitation bag. Incorrect flow settings may result in an incorrect estimation of NO delivery. If the flow into the manual equipment is too low, there is risk of overdosing the patient with NO.ALWAYS squeeze the bag several times, after starting fresh gas flow, to empty residual gas in the bag prior to using the System to ventilate patient. Failure to do so could result in higher NO2 levels being delivered to the patient.ALWAYS use the smallest bag adequate to deliver the desired tidal volume. Failure to do so could result in higher NO2 levels being delivered to the patient.Patient MonitoringALWAYS constantly monitor the patient. System malfunctions can occur if device and patient are not monitored and can result in injury or death. Careful monitoring is required by care personnel whenever the System is used on patient. The use of an alarm and monitoring system does not give an absolute assurance of warning for every malfunction that may occur. Certain alarms may require immediate response.Use with Breathing DevicesDO NOT use the GENOSYL DS with circle anesthesia ventilator systems. The GENOSYL DS has not been characterized or qualified for use with anesthesia breathing systems with recirculation of gases.ONLY use manual resuscitation bag with the GENOSYL DS for short time (e.g., less than one hour) when on battery only. Otherwise, the System may shut off and may result in injury or death.ALWAYS ensure the trigger sensitivity of the ventilator is checked after connecting the GENOSYL DS to the breathing circuit. The GENOSYL DS injects and samples gas from the patient respiratory circuit which may affect the triggering sensitivity of the ventilator.ALWAYS ensure the patient disconnect and high-pressure alarms are used with the ventilator. Otherwise, the System is not working properly.ONLY use the GENOSYL DS with Bio-Med Crossvent 2+/2i+ with Constant Flow ON. Not doing so may lead to elevated NO2 levels or dose variability.Set-upONLY VERO Biotech authorized equipment technicians are to perform the initial System set-up prior to initial use. Failure to use an authorized equipment technician can result in patient or user injury.ONLY store the GENOSYL DS as outlined in the storage instructions. Not storing the device in alignment with its storage instructions can cause the device to be unsafe and lead to injury or death.AVOID using the GENOSYL DS adjacent to or stacked with other equipment, as it may result in improper operation. If such use is necessary, this equipment and the other equipment should be observed to verify that they are operating normally.DO NOT use accessories or cables other than those specified or provided by the manufacturer of this equipment, as this may result in increased electromagnetic emissions or decreased electromagnetic immunity of this equipment and result in improper operation.DO NOT place portable RF communications equipment (including peripherals such as antenna cables and external antennas) closer than 30cm (12 inches) to any part of the GENOSYL DS, including cables specified. Otherwise, degradation of the performance of this equipment could occur, resulting in injury.Only connect to power outlet with protective earth.

The GENOSYL DS or any of its parts should not be serviced or repaired by anyone other than VERO Biotech Technical Engineer or without written permission from VERO Biotech Technical Engineering Department.Any malfunction resulting from faulty maintenance, improper repair, damage, alteration by anyone other than VERO Biotech Technical Engineer, and/or improper use will be the sole responsibility of the User.WARNINGThe GENOSYL DS must only be used in accordance with the approved indications, usage, contraindications, precautions, and warning described in the GENOSYL DS labeling. Refer to the labeling prior to use.CAUTIONU.S. Federal law restricts this device to sale by or on the order of physician. Outside the U.S., check local laws for any restrictions that may apply.NOTESPrior to using the GENOSYL DS, read through this Operators Manual.Follow all instructions and obey the Warnings and Cautions.Keep this Operators Manual available to readily answer questions.Read through all manufacturer Operators Manuals for the ventilator, humidifier and any other accessory texts used.1.2General Information and Indications for UseGENOSYL DS generates and delivers NO for inhalation at the point of use. The concentration of NO, as set by the user, is monitored, and adjusted to accurately dose the patient throughout an inspired breath. Only validated devices components should be used with the GENOSYL DS.The intended population for inhaled NO treatment is term and near-term neonates in neonatal intensive care units (NICUs). Refer to the GENOSYL (nitric oxide) for inhalation drug label for more detailed information.The GENOSYL DS is intended for use in the hospital and 1.5 Tesla and 3.0 Tesla diagnostic imaging environments.The GENOSYL DS is intended for use by healthcare professionals (HCPs) who are licensed and actively practicing pediatric and/or neonatal respiratory therapists (RTs) in the United States. These users are required to set up, administer inhaled Nitric Oxide and provide respiratory care (including initiation and maintenance of mechanical ventilators) in the critically ill neonatal population.The GENOSYL DS starts with liquid N2O4/NO2, which is then converted in proprietary Cassette to NO. The GENOSYL DS delivers NO into the ventilator stream, where the NO joins stream of air or O2 and is diluted to the prescribed concentration.The NO concentration (dose) to be delivered to the patient is selected by the user and is set and maintained independently by means of computer-controlled air pumps, Cassette heaters, and feedback loop that measures the delivered NO concentration.The GENOSYL DS takes gas sample removed from the NO gas flow stream immediately prior to the patient and provides real-time output of the NO, NO2, and O2 concentrations that are being delivered to the patient. The continuous integrated gas monitoring includes comprehensive alarm system.The NO concentration detected from the sample line is used in feedback loop to adjust the NO concentration delivered into the ventilator circuit.The GENOSYL DS includes redundant Console for complete Back-up capability for delivery of NO for inhalation. Each Console has back-up battery that provides at least hour of NO delivery in the absence of an external power source.1.3Principles of OperationGENOSYL DS. The GENOSYL DS continuously introduces precisely controlled concentration of Nitric Oxide (NO) into the inspiratory limb of the ventilator circuit. GENOSYL DS utilizes the known properties of NO and other oxides of nitrogen, namely dinitrogen tetroxide (N2O4) and nitrogen dioxide (NO2), to create tankless drug/device combination System to produce, at the point of use, ultra-high purity NO for inhalation, providing consistent, prescribed dose to the patient.Console. The GENOSYL DS Console contains the electronics to control the production and to maintain the constant and precise delivery of NO.The primary features of the Console front panel are displayed in Figure 1.Figure 1: GENOYL DS Console Front PanelNO generation. The Console uses Cassettes containing liquid N2O4/NO2 inside stainless-steel vessel (the liquid module) and an antioxidant cartridge. Upon initiation of Cassette, the liquid N2O4 is heated, producing NO2 gas, which is mixed with up to 0.9 LPM ambient air supplied by the Console. The NO2/air is injected into the antioxidant cartridge inside the Cassette, which converts NO2 to NO.The Cassette is designed to provide NO in concentrations up to 80 ppm. The maximum and minimum delivered dose for range of constant inspiratory flow rates is presented in Figure 2.The maximum combination of dose (ppm) and flow (LPM) output of the System is 800 ppm LPM (e.g., 20 ppm with 40 LPM, 40 ppm at 20 LPM, etc.). The System is capable of delivering NO at minimum of ppm LPM (e.g., ppm at LPM).Figure 2: Cassette Output RangeThe total time to deplete the Cassette N2O4 contents depends on the rate of use. The minimum time to depletion based on use rate is shown in Figure 3. The calculated minimum remaining contents at the current output rate is indicated by gauge presented on the Console display during use.Figure 3: Calculated Time to Cassette DepletionNO Injection into the Ventilator Circuit. After NO is produced in the Cassette, the NO injector introduces the concentrated NO into the ventilator circuit where the NO is diluted to the prescribed concentration (dose) and mixed with the O2 or air supplied to the patient.Before the gas mixture reaches the patient, sample line removes small gas sample and sends it back to the Console, where gas sensors continuously measure the supplied NO, NO2 and O2. The Console software then compares the measured NO concentration to the set NO concentration and continuously adjusts the delivery of NO to maintain the prescribed NO concentration (dose) delivered to the patient (closed loop control). The Console software commands the NO injection flow rate into the ventilator circuit with maximum flow rate of 0.9 LPM. Changes in the ventilator settings by the user may cause brief transient changes in the measured NO value. The Console software will adjust the injected flow rate and the internal temperature of the Cassette to compensate for the changes in the total ventilator flow rate. For example, higher minute ventilation will require higher injection flow rate to produce the same NO concentration.Mixer. An inline Mixer is used in the applicable ventilator circuit after the NO injection site and before the gas sample site to mix NO from the Console with the gas supplied by the ventilator, for specific ventilator and tidal volume use cases per Section 10.2.Gas Monitoring. The gas mixture delivered to the patient by the GENOSYL DS is continuously monitored with two NO detectors, with one providing redundant back-up, as well as detector for NO2 and O2. sample of inspired gas is taken from the inspiratory limb, close to the patient, and is measured by the gas sensor within the Console. The gas monitoring sensors are electrochemical; they are specific to each gas and provide an electronic signal that is proportional to the concentration of gas present.Adaptive Sensor. The Adaptive Sensor is used to detect flow in the patient breathing circuit. When flow is not detected by the Adaptive Sensor, Nitric Oxide delivery will be interrupted until flow is detected. The Console will provide visual and audible high priority alarm when flow is not detected to alert the user (see Section 8.2). Once flow is detected, the Console will auto resume delivery of nitric oxide at the previously set dose. An Adaptive Sensor is recommended for use with certain breathing devices. Refer to Section for recommended set up diagrams. The GENOSYL DS will properly deliver and control Nitric Oxide dose in the absence of an Adaptive Sensor.Alarms and Dosing Safeguard Fallback Modes. The GENOSYL DS alerts the user in the event of excursions of NO, NO2, and Oxygen from their expected ranges. Nitric Oxide delivery interruption conditions are as follows:a) NO 100 ppmb) NO2 reaches ppmc) The measured respiratory circuit dilution flow drops below 0.3 SLPM as measured by the Adaptive Sensor.The Console will provide visual and audible high priority alarm. When detecting sustained gas level higher than the above limits for 11 consecutive seconds, the Console will interrupt delivery of NO until the sampled levels of NO and/or NO2 decrease to safe level. Once sampled levels are in acceptable range, the Console will resume delivery with previously set dose.If the cause of the high gas cannot be resolved, the use of the Back-up Console may be required. Refer to Section 8.1 for additional information on alarms and dosing safeguards.If NO delivery was interrupted due to the GENOSYL DS Adaptive Sensor reading dropping below 0.3 SLPM, the Console will resume delivery with the previously set dose once the Adaptive Sensor reading exceeds 0.35 SLPM. The automatic resumption of dose delivery after the interruption conditions listed above are cleared is one of the safety fallback modes of the GENOSYL DS.Back-up NO Delivery. The Back-up Console is used to administer Nitric Oxide when the Dosing Console cannot be used. This Console has separate power supply, and at least one Cassette loaded and preheated. If the Dosing Console fails to deliver NO, the Back-up Console is ready to begin dosing to continue NO delivery.Transition to new Cassette. When Cassette approaches depletion, the Dosing Console will automatically transition to the second Cassette in the Console. Once the dosing Cassette is depleted, the Dosing Console will eject the depleted Cassette and alert the user to replace via the Cassette Status Indicator.Disposal of the Cassette. Following use, any remaining Cassette contents are purged into an inerting chamber, where the contents are chemically neutralized, rendering the Cassette safe for disposal.1.4 Exposure of Healthcare Providers to NO and NO2 Occupational exposure of healthcare providers to NO or NO2 may occur during Inhaled NO therapy for patients. Below are examples of calculated and observed exposure to NO or NO2, in the context of guideline workplace exposure limits.Calculated and observational methods show that the exposure levels to NO or NO2 from an NO delivery System are significantly less than the levels recommended by the National Institute for Occupational Safety and Health (NIOSH).Workplace Limits: NIOSH has recommended workplace exposure limits as followsNIOSH Pocket Guide to Chemical Hazards, Dept of Health Human Services, Centers for Disease Control and Prevention, National Inst for Occupational Safety Health. Publication 2005-149, Sept 2007..NOtime-weighted (8 hours) average concentration limit of 25 ppmNO2 Recommended exposure limit of ppmTheoretical Calculation. The build-up of NO in well-ventilated ICU room, with NO flowing directly into the room, can be evaluated using the following calculation:Room size1000 ft3 Room volume28,300 LRoom ventilation (6 complete exchanges/hour)2,830 L/minNO flow into the room80 ppm at 14 L/minAverage NO room concentration (80 14) 2,830 0.396 ppm (0.4 ppm)0.4 ppm of NOObservations of NO Exposure. The theoretical calculation has been supplemented by actual measurements in three independent studies in actual therapeutic use settings.Hess et al, Use of Inhaled Nitric Oxide in patients with Acute Respiratory Distress Syndrome.

Calibration of the GENOSYL DS should be performed every 14 days to ensure the accuracy of NO, NO2, and O2 measurements. All calibrations can be performed at any time the Console is powered on, including while actively dosing. Air calibrates the low range for the NO and NO2 sensors. The high range of the NO and NO2 sensors are calibrated by using calibration gas tanks. The software will notify the user when calibration is due.The display within the calibration tab provides the status and the calibration due date of the different types of sensors. Air calibration provides the time of the last calibration since the System automatically performs this calibration every hours while actively dosing or every 24 hours while powered on. green check under status indicates that sensor has successfully been executed within the calibration period. red under status indicates that the sensor has not successfully been executed within the calibration period. During calibration, the display will provide measured readings from each sensor. Note, there are two redundant NO sensors which are used to verify and ensure accuracy of the dosage provided by the System. During calibration, the display will provide real-time status of the test with colored boxes to the right of the displayed sensor output. yellow box indicates that the sensor is being calibrated. green box indicates that calibration was successful for that sensor. red box indicates that calibration for that sensor failed. WARNINGONLY use the calibration gas pressure regulators supplied by the manufacturer. Pressure regulators not supplied by the manufacturer may damage the sensors and may lead to patient injury. ALWAYS verify the correct NIST traceable calibration gas is being used and confirm the expiration date of the calibration gas prior to performing calibration. The use of incorrect or expired gas may result in inaccurate sensor readings and can lead to patient injury.NEVER perform NO or NO2 calibration within the MR scanner room. Calibration equipment is potential projectile hazard.CAUTIONALWAYS perform full-scale calibration of the GENOSYL DS when prompted by the System prior to use.ALWAYS confirm the correct flow direction of the installed one-way check valve in the sampling tee to avoid over pressurization of the sample system and damage to the device.9.1.1Air CalibrationDISPLAYACTIONWarnings, Cautions and Notes1.Check to make sure nothing is connected to the CAL port during Air Calibration.2.

Failure to recharge the Console battery for extended timeframes may result in full discharge of the battery. If Battery Error message occurs during startup of the System, contact Technical Support at 877-337-4118 for assistance.ONLY properly trained personnel should replace the battery. Incorrectly replacing the battery may result in hazard such as excessive temperatures, fire, or explosion.ONLY store the GENOSYL DS as outlined in the storage instructions. Not storing the device in alignment with its storage instructions can cause the device to be unsafe and lead to injury or death. 9.7.2Cassette Accessory StorageGENOSYL DS may not function correctly if the Cassette or any of the System Accessories have been exposed to high levels of heat or humidity. Cassettes are supplied in plastic container and should remain unopened until use. Cassettes should be stored at 25C (77F) with excursions permitted between 15C to 30C (59F to 86F). (See USP Controlled Room Temperature).GENOSYL(R) DSSECTION 10MECHANICAL VENTILATION10. MECHANICAL VENTILATIONWARNINGONLY mechanical ventilators validated with the GENOSYL DS should be used. Not using validated ventilator system can result in injury or harm.DO NOT use the GENOSYL DS with circle anesthesia ventilator systems. The GENOSYL DS has not been characterized or qualified for use with anesthesia breathing systems with recirculation of gases. 10.1Mechanical VentilationThere are two main effects of connecting the GENOSYL DS to ventilator breathing circuit:The System injects up to 0.9 LPM of NO/air (21% Oxygen) into the inspiratory output of the ventilator. The System samples up to 0.3LPM from the ventilator circuit as measurement to the built-in gas analyzersThe results of adding and subtracting gas into the ventilator circuit are described in sections 10.1.1 to 10.1.4:10.1.1 Oxygen DilutionThe ventilator typically is flowing gas to the patient with enhanced oxygen content from room air at 21% to pure oxygen at 100%. The DS is injecting the NO in air with concentration of oxygen at nominally 21%. Thus, except for the case where the ventilator is supplying gas to the patient at 21% oxygen, there is some dilution of the oxygen to the patient. This dilution is given by the following equation:Percent O2 to Patient [%O2/100 (Flowinj/Flowvent)x0.21/1 (Flowinj/Flowvent)]x100Where: Flowinj Injection flow in same units as ventilator flow Flowvent Ventilator flow in same units as injection flow %O2 Percent oxygen out of ventilator 0.21 Fraction of oxygen in injection flow (21%)The table below shows the effect on the actual concentration of oxygen supplied to the patient for set ventilator flow settings with nominal flow of 0.6 LPM of NO/air (21% Oxygen) into the inspiratory output of the ventilator.Table 7: Oxygen DilutionOxygen (%) Supplied from Ventilator10080604021Ventilator Flow (LPM)Oxygen (%) Delivered to Patient2098785939211597785939211096775839219957658392189476573921794755739216937556382159274563821490725538213877054372110.1.2 Minute VolumeWhen using volume ventilation with the GENOSYL DS, the tidal volume delivered to the patient may show small changes due to the addition and subtraction of gases by the Delivery System. Some minor ventilator adjustments to the minute volume may be required. Maximum total flow added to the ventilator circuit is 0.9 LPM of concentrated NO gas and the maximum total flow removed from the ventilator circuit is 0.3 LPM of sampled gas.10.1.3 Trigger SensitivityThe addition and subtraction of gases by the GENOSYL DS may affect the trigger sensitivity of the ventilator when using synchronized modes of ventilation. This may cause the ventilator to auto-trigger in ventilators which have flow trigger modes, especially where the trigger flow is less than the total flow added to the System.10.1.4 Maximum NO DeliveryThe maximum combination of dose (ppm) and flow (LPM) is 800. ppm LPM (e.g., 20 ppm with 40 LPM, 40 ppm at 20 LPM, etc.). The System is capable of delivering NO at minimum of ppm LPM (e.g., ppm at LPM). See the graph below for the minimum and maximum dose ranges for the System, based on ventilator circuit total minute volume.Figure 24: Cassette Output Range10.2 Ventilator CompatibilityThe GENOSYL DS is compatible with the following equipment and accessories.Table 8: Compatible Equipment and AccessoriesMANUFACTURERTYPE OF EQUIPMENTMODELFisher PaykelVent circuit kitRT265Fisher PaykelVent circuit kitRT210Fisher PaykelHumidifier850Fisher PaykelHumidifier ChamberMR 290MedlineHyperinflated Resuscitator Resus Hyperinf System 1/2L-LFLaerdalSelf-inflated ResuscitatorInfant Silicone ResuscitatorsVERO Biotech performs validation testing which determines the compatibility of ventilator/gas delivery systems with the GENOSYL DS. During this compatibility testing, the GENOSYL DS is evaluated for the following parameters while connected to each ventilator/gas delivery system:NO Dose Accuracy: Continuous and accurate delivery of targeted dose of Nitric Oxide within +- 20% of setpoint or within +/- ppm, whichever is greater.Respiratory Device Breath Delivery and Alarms: The respiratory device breath delivery and alarms continue to function as intended by the manufacturer across the range of operating conditions.NO2 Performance: NO2 remains within acceptable limits less than 1.0 ppm with 60% FiO2 and <=40 ppm NO. O2 Dilution: Post dilution O2 level delivery is maintained within acceptable limits and conforms with the information presented in the GENOSYL DS Operators Manual, Section 10.1.1, Oxygen Dilution.NO Concentration Transients: NO concentration transients are <=150% of mean concentration and as low as 0.0 ppm as long as the transient duration does not exceed 10% of the volumetric duration of the breath.The testing performed demonstrated conformance with all specified requirements. The following ventilators and non-invasive gas delivery systems in Table have been validated for use with the GENOSYL DS. See Section 3.2 for use configurations. Use of Mixer is recommended when delivering in specific tidal volume ranges on various ventilation devices. Refer to Table 10 for when Mixer is and is not recommended.WARNINGALWAYS use the GENOSYL DS in accordance with the indications, usage, contraindications, warnings, and precautions described in the GENOSYL prescribing information and labeling. Refer to latest approved prescribing information and labeling prior to use.The approved patient population for the GENOSYL DS as specified in the drug labeling for GENOSYL (nitric oxide) for inhalation, is limited to neonates. The GENOSYL DS is not intended to be used in other patient populations.Table 9: Details of Validated SystemsManufacturerModelNeonatalPediatric/AdultCPAPHFNCMRBio-Med DevicesCrossvent 2+/2i+ooBio-Med DevicesMVP-10ooDragerVN500ooDragerV500ooGE HealthcareR860ooHamiltonC1/T1ooHamiltonC2/C3ooHamiltonMR1oooHamiltonG5ooMaquetServo-U/N/IooMaquetServo-I MRoooPuritan Bennett840ooPuritan Bennett980ooVyaire Medical Inc.AVEAooFisher PaykelOptiflow Junior Breathing CircuitoFisher and PaykelOptiflow Breathing CircuitoFisher PaykelBubble CPAP SystemoSee Section 3.4 for assembly instructions for Injection Assembly with Adaptive Sensor and Mixer Assembly with Adaptive Sensor.Table 10: Validated Compatibility with and without Inline MixerManufacturerModelVentilator Range Tested: NeonatalVentilator Range Tested:Pediatric/AdultVentilator Circuit using Injection Assembly with Adaptive SensorVentilator Circuit using Injection Assembly with Adaptive Sensor Ventilator Circuit using Mixer Assembly with Adaptive Sensor (Without Inline Mixer) (Without Inline Mixer) (With Inline Mixer)Key:o Range Fully tested; use of Inline Mixer is not requiredVT: Tidal VolumeVT Value listed: Tidal volumes in this range have been validated in accordance with column header (with or without Inline Mixer)Bio-Med DevicesCrossvent 2+/2i+ooN/ABio-Med DevicesMVP-10ooN/ADragerVN500ooN/ADragerV500oVT 400 mLVT 400 600 mLGE HealthcareR860oVT 350 mLVT 350 650 mLHamiltonC1/T1oVT <= 450 mLVT 450 600 mLHamiltonC2/C3oVT <= 470 mLVT 470 950 mLHamiltonMR1oVT <= 470 mLVT 470 950 mLHamiltonG5oVT <= 950 mLVT 950 1400 mLMaquetServo-U/N/IoVT <= 650 mLVT 650 740 mLMaquetServo-I MRoVT <= 650 mLVT 650 740 mLPuritan Bennett840oVT <= 300 mLVT 300-760 mLPuritan Bennett980oVT <= 485 mLVT 485 1100 mLVyaire Medical Inc.AVEAoVT 540 mLVT >= 540 mLGENOSYL(R) DSSECTION 11PRODUCT SPECIFICATIONS11PRODUCT SPECIFICATIONS11.1System PerformanceNO DOSINGAccuracy+/- 20% or +/- ppm (whichever is greater)Range0 to 80 ppmFlow rate (max)900 mL/minGAS SENSORRangeResolutionAccuracyNO0 10 ppm0.1 ppm<=20 ppm: +/- (20% of actual concentration 0.5)>20 ppm:+/- (10% of actual concentration 0.5)10 100 ppm1 ppmNO2 0.0 12 ppm0.1 ppm+/- (20% of actual concentration 0.5 ppm)O2 18 100%1%+/- volume fraction of 2.5% +2.5% of gas level11.1.1System ClassificationClass equipmentOrdinary Equipment IPX1Continuous UseEssential Performance: The System shall continue to deliver controlled dose, as configured by the user (e.g., 20 ppm LPM within +/- 20%) with NO2 3 ppm and O2 21 +/- 3% in room air for the specified range of use conditions.11.1.2 TestingANSI ES 60601-1IEC 60601-1-2IEC 60601-1-811.1.3 ElectricalNOTEDisconnect main power cord from the wall outlet to isolate equipment from main power.

Testing was conducted using standard American College of Radiology (ACR) sequences and standard ACR large phantom placed inside transmit-receive head coil. Duplicate sequences were performed to acquire the same images with and without the GENOSYL DS Nitric Oxide Delivery System operating on battery power inside the MRI suite.The GENOSYL DS compatibility test results are as follows:Artifact Dimensional Analysis1.5 TThe maximum dimensional change in images acquired during the operation of the GENOSYL DS was 1 mm.3 TThe maximum dimensional change in images acquired during the operation of the GENOSYL DS was 1 mm.Image Quality Signal-to-Noise Ratio Analysis1.5 TThe average SNR change was -35%. The average SFNR change was -42%. The PIU values were all 96%.3 TThe average SNR change was -25%. The average SFNR change was -22%. The PIU values were all greater than 94%.The GENOSYL DS does not distort the geometric accuracy and the image intensity uniformity is not adversely affected by the presence of the GENOSYL DS at the 100 Gauss line. The SNR and SFNR are both impacted by the presence of the GENOSYL DS, to more pronounced degree when the equipment is powered via wall outlet inside the MRI suite versus operating on the battery.NOTEThe test results presented here were obtained with the GENOSYL DS operating on battery power.If using the GENOSYL DS while connected to wall power, it is recommended to route the power cords through waveguide.11.6EMI/EMCEmissions testComplianceElectromagnetic Environment GuidanceRF emissionsCISPR 11Group 1The GENOSYL DS uses RF energy only for its internal function.

For this reason, an additional factor of 10/3 is used in calculating the recommended separation distance for transmitters in these frequency ranges. Radiated RFIEC 61000-4-310 /m 80MHz to 2.7 GHz 10 /m 80 MHz to 2.7 GHz Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey,Field strengths from fixed transmitters, such as base stations for radio (cellular cordless) telephones and land mobile radios, amateur radio, AM and M radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the GENOSYL DS is used exceeds the applicable RF compliance level above, the GENOSYL DS should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the GENOSYL DS. should be less than the compliance level in each frequency range.Over the frequency range 150 kHz to 80MHz, field strengths should be less than V/m.Interference may occur in the vicinity of equipment marked with the following symbol: NOTENOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.Recommended separation distances between portable and mobile RF communications equipment and the GENOSYL DSThe GENOSYL DS is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the GENOSYL DS can help prevent electromagnetic interference by maintaining minimum distance between portable and mobile RF communications equipment (transmitters) and the GENOSYL DS as recommended below, according to the maximum output power of the communications equipment except as indicated on page 10-166.Rated Maximum Output Power of Transmitter WSeparation Distance

Maximum static magnetic field of 100 Gauss (0.01mT). Device remains outside the scanner bore. Preparation protocols described in the Warnings section textd Use in the MR Environment must be followed before MR procedure. ALWAYS acknowledge and follow information provided from alarms. An alarm indicates an abnormal condition, and ignoring alarms can result in possible injury, death, or serious adverse reactions.. ALWAYS use clinical judgement when setting upper or lower alarm limits. Failure to do so could result in possible injury or death.. ALWAYS have second Console present and properly connected when Dosing Console is connected to the patient. If the Dosing Console malfunctions, switch to the Back-up Console. If the Back-up Console is not available or properly connected, this may result in patient injury or death.. DO NOT clean the GENOSYL DS with the power connected and the System turned ON, as this may lead to injury (e.g., shock). Unplug AC/DC power supply external to the System prior to cleaning.. NEVER modify the equipment. Modifications of the equipment may result in malfunction, which may result in fire, shock, injury, or death.. NEVER turn the rear power switch OFF until the System has gone through controlled shutdown or instructed by VERO Technical Support. Turning the rear power switch OFF prematurely (e.g., while it is still in use) will immediately shut down the device. This may result in interruption in NO delivery to the patient, which may cause injury or death.. DO NOT use the Cassette if the Cassette State Window is not blue. Cassette State Window that is any color other than blue may affect the Cassettes ability to provide the correct NO dosage to the patient, which may cause injury or death.. DO NOT use Cassette that is beyond its expiration date. Using an expired Cassette may affect the Cassettes ability to provide the correct NO dosage to the patient, which may cause injury or death.. MAKE SURE the System stabilizes to the prescribed concentration (ppm) of NO prior to leaving the Console unattended. Failure to do so could result in under delivery of the target NO, leading to injury or harm.. ALWAYS replace Cassette once depleted. depleted Cassette will interrupt patient dosing and can lead to under dosing and/or injury to the patient.. ALWAYS follow Cassette inspection instructions prior to Cassette insertion. Not inspecting the Cassette prior to insertion may lead to using faulty Cassette, resulting in injury.. The GENOSYL DS is classified as MR Conditional with MR scanners of 1.5 or 3.0 Tesla strength ONLY in areas where the field strength is less than 100 gauss.. ALWAYS operate at fringe field of less than 100 gauss. This device contains ferromagnetic components and may experience strong attraction close to the magnet.. DO NOT exceed 100 gauss; System operation may be impacted. Confirm Cart caster lock function. Optionally connect tether.. NEVER use the GENOSYL DS in the MR scanner room without gauss alarms installed.. ALWAYS verify at least one gauss alarm is functioning properly prior to use in the MR environment.. DO NOT use the GENOSYL DS in the MR environment if neither gauss alarm is functional.. ALWAYS move System away from the MR scanner if the gauss alarm sounds. The gauss alarm will sound if the System is too close to the MR scanner. Move System away from the MR scanner until the gauss alarm stops sounding.. ALWAYS verify that the GENOSYL DS Cart casters are locked after positioning the System in the MR scanner room.. ALWAYS verify that the GENOSYL DS is securely attached to the Cart.. ALWAYS arrange power cord, MR patient gas sample line, and NO delivery line to avoid entanglement, strangulation and/or trip hazard.. DO NOT use the GENOSYL DS in the MR environment if the Cart moves when the brake caster locks are engaged.. NEVER perform NO or NO2 calibration within the MR scanner room. Calibration equipment is potential projectile hazard.. ALWAYS follow pre-use setup instructions for the routing and connections of tubing to avoid patient strangulation.. MAKE SURE the System has all tubing connected as described in the instructions. Not connecting all tubing may result in inaccurate dosage and harm the patient.. NEVER touch the electrical connectors of the System or its accessories, and the patient simultaneously. If the user touches another device with ground-fault failure and simultaneously touches the GENOSYL DS, this can result in injury (e.g., shock) should grounding failure be present.. ONLY properly trained personnel should replace the battery. Incorrectly replacing the battery may result in hazard such as excessive temperatures, fire, or explosion.. MAKE SURE the GENOSYL DS is connected to AC wall power to charge the battery minimum of once every months to maintain minimum battery charge. Failure to recharge the Console battery for extended timeframes may result in full discharge of the battery. If Battery Error message occurs during startup of the System, contact Technical Support at 877-337-4118 for assistance.. ONLY intended users who are experienced in the use of this System should use this device. US federal law restricts device use to licensed medical professionals. If device is used by unintended users, device can be misused and lead to injury or death.. ALWAYS ensure that the manual flow displayed on the Console matches the flow set into the resuscitation bag. Incorrect flow settings may result in an incorrect estimation of NO delivery. If the flow into the manual equipment is too low, there is risk of overdosing the patient with NO.. ALWAYS squeeze the bag several times, after starting fresh gas flow, to empty residual gas in the bag prior to using the System to ventilate patient. Failure to do so could result in higher NO2 levels being delivered to the patient.. ALWAYS use the smallest bag adequate to deliver the desired tidal volume. Failure to do so could result in higher NO2 levels being delivered to the patient.. ALWAYS constantly monitor the patient. System malfunctions can occur if device and patient are not monitored and can result in injury or death. Careful monitoring is required by care personnel whenever the System is used on patient. The use of an alarm and monitoring system does not give an absolute assurance of warning for every malfunction that may occur. Certain alarms may require immediate response.. DO NOT use the GENOSYL DS with circle anesthesia ventilator systems. The GENOSYL DS has not been characterized or qualified for use with anesthesia breathing systems with recirculation of gases.. ONLY use manual resuscitation bag with the GENOSYL DS for short time (e.g., less than one hour) when on battery only. Otherwise, the System may shut off and may result in injury or death.. ALWAYS ensure the trigger sensitivity of the ventilator is checked after connecting the GENOSYL DS to the breathing circuit. The GENOSYL DS injects and samples gas from the patient respiratory circuit which may affect the triggering sensitivity of the ventilator.. ALWAYS ensure the patient disconnect and high-pressure alarms are used with the ventilator. Otherwise, the System is not working properly.. ONLY use the GENOSYL DS with Bio-Med Crossvent 2+/2i+ with Constant Flow ON. Not doing so may lead to elevated NO2 levels or dose variability.. ONLY VERO Biotech authorized equipment technicians are to perform the initial System set-up prior to initial use. Failure to use an authorized equipment technician can result in patient or user injury.. ONLY store the GENOSYL DS as outlined in the storage instructions. Not storing the device in alignment with its storage instructions can cause the device to be unsafe and lead to injury or death.. AVOID using the GENOSYL DS adjacent to or stacked with other equipment, as it may result in improper operation. If such use is necessary, this equipment and the other equipment should be observed to verify that they are operating normally.. DO NOT use accessories or cables other than those specified or provided by the manufacturer of this equipment, as this may result in increased electromagnetic emissions or decreased electromagnetic immunity of this equipment and result in improper operation.. DO NOT place portable RF communications equipment (including peripherals such as antenna cables and external antennas) closer than 30cm (12 inches) to any part of the GENOSYL DS, including cables specified. Otherwise, degradation of the performance of this equipment could occur, resulting in injury.. Only connect to power outlet with protective earth. Failure to connect to an outlet with protective earth may result in an electrical shock.. ALWAYS ensure patient safety before troubleshooting (such as an activated alarm) or replacing problematic text. Not monitoring the patient prior to attending to an alarm can result in injury or death.. ONLY use the calibration gas pressure regulators supplied by the manufacturer. Pressure regulators not supplied by the manufacturer may damage the sensors and may lead to patient injury.. ALWAYS verify the correct NIST traceable calibration gas is being used and confirm the expiration date of the calibration gas prior to performing calibration. The use of incorrect or expired gas may result in inaccurate sensor readings and can lead to patient injury.. NEVER submerge the GENOSYL DS, Cassettes, or non-disposable Adaptive Sensor Cable. Submerging in liquids will damage the System and could cause electrical shorts which may result in injury or death.. ALWAYS empty Water Trap when prompted by the System, and when the trap is more than half full. Allowing the Water Trap to completely fill will occlude the Sample Line which will interrupt patient gas NO, NO2, and O2 concentration monitoring. Failure to monitor the patient gas NO, NO2, and O2 concentrations may result in patient injury.. ALWAYS conduct Water Trap/ Sample Line Leak Test every time you empty and replace the Water Trap, as failure to do so may lead to an incorrect NO reading, which can result in injury or death.. ALWAYS use Water Trap supplied by the manufacturer. Using an incorrect Water Trap could result in non-functioning or inaccurate sensor readings..

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. No evidence of carcinogenic effect was apparent, at inhalation exposures up to the recommended dose (20 ppm), in rats for 20 hr/day for up to two years. Higher exposures have not been investigated.Nitric oxide gas has demonstrated genotoxicity in Salmonella (Ames Test), human lymphocytes, and after in vivo exposure in rats. There are no animal or human studies to evaluate nitric oxide for effects on fertility.

CLINICAL PHARMACOLOGY SECTION.

12 CLINICAL PHARMACOLOGY. 12.1 Mechanism of Action. Nitric oxide relaxes vascular smooth muscle by binding to the heme moiety of cytosolic guanylate cyclase, activating guanylate cyclase and increasing intracellular levels of cyclic guanosine 3,5-monophosphate, which then leads to vasodilation. When inhaled, nitric oxide selectively dilates the pulmonary vasculature, and because of efficient scavenging by hemoglobin, has minimal effect on the systemic vasculature.GENOSYL appears to increase the partial pressure of arterial oxygen (PaO2) by dilating pulmonary vessels in better ventilated areas of the lung, redistributing pulmonary blood flow away from lung regions with low ventilation/perfusion (V/Q) ratios toward regions with normal ratios.. 12.2 Pharmacodynamics. Effects on Pulmonary Vascular Tone in PPHNPersistent pulmonary hypertension of the newborn (PPHN) occurs as primary developmental defect or as condition secondary to other diseases such as meconium aspiration syndrome (MAS), pneumonia, sepsis, hyaline membrane disease, congenital diaphragmatic hernia (CDH), and pulmonary hypoplasia. In these states, pulmonary vascular resistance (PVR) is high, which results in hypoxemia secondary to right-to-left shunting of blood through the patent ductus arteriosus and foramen ovale. In neonates with PPHN, nitric oxide gas for inhalation improves oxygenation (as indicated by significant increases in PaO2).. 12.3 Pharmacokinetics. The pharmacokinetics of nitric oxide has been studied in adults.. Absorption and DistributionNitric oxide is absorbed systemically after inhalation. Most of it traverses the pulmonary capillary bed where it combines with hemoglobin that is 60% to 100% oxygen-saturated. At this level of oxygen saturation, nitric oxide combines predominantly with oxyhemoglobin to produce methemoglobin and nitrate. At low oxygen saturation, nitric oxide can combine with deoxyhemoglobin to transiently form nitrosylhemoglobin, which is converted to nitrogen oxides and methemoglobin upon exposure to oxygen. Within the pulmonary system, nitric oxide can combine with oxygen and water to produce nitrogen dioxide and nitrite, respectively, which interact with oxyhemoglobin to produce methemoglobin and nitrate. Thus, the end products of nitric oxide that enter the systemic circulation are predominantly methemoglobin and nitrate.. MetabolismMethemoglobin disposition has been investigated as function of time and nitric oxide exposure concentration in neonates with respiratory failure. The methemoglobin (MetHb) concentration-time profiles during the first 12 hours of exposure to 0, 5, 20, and 80 ppm nitric oxide are shown in Figure 1.Methemoglobin concentrations increased during the first hours of nitric oxide exposure. The mean methemoglobin level remained below 1% in the placebo group and in the ppm and 20 ppm nitric oxide gas groups, but reached approximately 5% in the 80 ppm nitric oxide gas group. Methemoglobin levels >7% were attained only in patients receiving 80 ppm, where they comprised 35% of the group. The average time to reach peak methemoglobin was 10 +- (SD) hours (median, hours) in these 13 patients, but one patient did not exceed 7% until 40 hours.. Figure 1. EliminationNitrate has been identified as the predominant nitric oxide metabolite excreted in the urine, accounting for >70% of the nitric oxide dose inhaled. Nitrate is cleared from the plasma by the kidney at rates approaching the rate of glomerular filtration.

CLINICAL STUDIES SECTION.

14 CLINICAL STUDIES. 14.1 Treatment of Hypoxic Respiratory Failure (HRF). The efficacy of nitric oxide gas was investigated in term and near-term newborns with hypoxic respiratory failure (HRF) resulting from variety of etiologies. Inhalation of nitric oxide gas reduces the oxygenation index (OI= mean airway pressure in cm H2O fraction of inspired oxygen concentration [FiO2]x 100 divided by systemic arterial concentration in mm Hg [PaO2]) and increases PaO2 [see Clinical Pharmacology (12.1)].. NINOS StudyThe Neonatal Inhaled Nitric Oxide Study (NINOS) was double-blind, randomized, placebo-controlled, multicenter trial in 235 neonates with hypoxic respiratory failure. The objective of the study was to determine whether inhaled nitric oxide would reduce the occurrence of death and/or initiation of extracorporeal membrane oxygenation (ECMO) in prospectively defined cohort of term or near-term neonates with hypoxic respiratory failure unresponsive to conventional therapy. Hypoxic respiratory failure was caused by meconium aspiration syndrome (MAS; 49%), pneumonia/sepsis (21%), idiopathic primary pulmonary hypertension of the newborn (PPHN; 17%), or respiratory distress syndrome (RDS; 11%). Infants <=14 days of age (mean, 1.7 days) with mean PaO2 of 46 mmHg and mean oxygenation index (OI) of 43 cm H2O mmHg were initially randomized to receive 100% O2 with (n=114) or without (n=121) 20 ppm nitric oxide for up to 14 days. Response to study drug was defined as change from baseline in PaO2 30 minutes after starting treatment (full response >20 mmHg, partial 10-20 mmHg, no response <10 mmHg). Neonates with less than full response were evaluated for response to 80 ppm nitric oxide or control gas. The primary results of this study are presented in Table 1.Table 1: Summary of Clinical Results from Hypoxic Respiratory Failure StudyControl (n=121)Nitric Oxide gas (n=114)P valueDeath or ECMOExtracorporeal membrane oxygenation Death or need for ECMO was the parimary end point of this study 77 (64%)52 (46%)0.006Death20 (17%)16 (14%)0.60ECMO66 (55%)44 (39%)0.014Although the incidence of death by 120 days of age was similar in both groups (NO, 14%; control 17%), significantly fewer infants in the nitric oxide group required ECMO compared with controls (39% vs. 55%, = 0.014). The combined incidence of death and/or initiation of ECMO showed significant advantage for the nitric oxide treated group (46% vs. 64%, = 0.006). The nitric oxide group also had significantly greater increases in PaO2 and greater decreases in the OI and the alveolar-arterial oxygen gradient than the control group (p<0.001 for all parameters). Significantly more patients had at least partial response to the initial administration of study drug in the nitric oxide group (66%) than the control group (26%, p<0.001). Of the 125 infants who did not respond to 20 ppm nitric oxide control, similar percentages of NO-treated (18%) and control (20%) patients had at least partial response to 80 ppm nitric oxide gas for inhalation or control drug, suggesting lack of additional benefit for the higher dose of nitric oxide. No infant had study drug discontinued for toxicity. Inhaled nitric oxide gas had no detectable effect on mortality. The adverse events collected in the NINOS trial occurred at similar incidence rates in both treatment groups [see Adverse Reactions (6.1)]. Follow-up exams were performed at 18-24 months for the infants enrolled in this trial. In the infants with available follow-up, the two treatment groups were similar with respect to their mental, motor, audiologic, or neurologic evaluations.. CINRGI StudyThis study was double-blind, randomized, placebo-controlled, multi-center trial of 186 term and near-term neonates with pulmonary hypertension and hypoxic respiratory failure. The primary objective of the study was to determine whether nitric oxide gas would reduce the receipt of ECMO in these patients. Hypoxic respiratory failure was caused by MAS (35%), idiopathic PPHN (30%), pneumonia/sepsis (24%), or RDS (8%). Patients with mean PaO2 of 54 mmHg and mean OI of 44 cm H2O mmHg were randomly assigned to receive either 20 ppm nitric oxide gas (n=97) or nitrogen gas (placebo; n=89) in addition to their ventilatory support. Patients who exhibited PaO2 >60 mmHg and pH 7.55 were weaned to ppm nitric oxide gas or placebo. The primary results from the CINRGI study are presented in Table 2.Table 2: Summary of Clinical Results from Persistent Pulmonary Hypertension of the Newborn StudyPlaceboNitric oxide gasP valueECMOExtracorporeal membrane oxygenation ECMO was the primary end point of this study 51/89 (57%)30/97 (31%)<0.001Death5/89 (6%)3/97 (3%)0.48Significantly fewer neonates in the nitric oxide gas group required ECMO compared to the control group (31% vs. 57%, p<0.001). While the number of deaths were similar in both groups (Nitric oxide gas, 3%; placebo, 6%), the combined incidence of death and/or receipt of ECMO was decreased in the nitric oxide gas group (33% vs. 58%, p<0.001).In addition, the nitric oxide gas group had significantly improved oxygenation as measured by PaO2, OI, and alveolar-arterial gradient (p<0.001 for all parameters). Of the 97 patients treated with nitric oxide gas, (2%) were withdrawn from study drug due to methemoglobin levels >4%. The frequency and number of adverse events reported were similar in the two study groups [see Adverse Reactions (6.1)].In clinical trials, reduction in the need for ECMO has not been demonstrated with the use of inhaled nitric oxide in neonates with congenital diaphragmatic hernia (CDH).. 14.2Ineffective in Adult Respiratory Distress Syndrome (ARDS). In randomized, double-blind, parallel, multicenter study, 385 patients with adult respiratory distress syndrome (ARDS) associated with pneumonia (46%), surgery (33%), multiple trauma (26%), aspiration (23%), pulmonary contusion (18%), and other causes, with PaO2/FiO2 <250 mmHg despite optimal oxygenation and ventilation, received placebo (n=193) or nitric oxide gas (n=192), ppm, for hours to 28 days or until weaned because of improvements in oxygenation. Despite acute improvements in oxygenation, there was no effect of nitric oxide gas on the primary endpoint of days alive and off ventilator support. These results were consistent with outcome data from smaller dose ranging study of nitric oxide (1.25 to 80 ppm). GENOSYL (nitric oxide) for inhalation is not indicated for use in ARDS.. 14.3Ineffective in Prevention of Bronchopulmonary Dysplasia (BPD). The safety and efficacy of nitric oxide gas for the prevention of chronic lung disease [bronchopulmonary dysplasia (BPD)] in neonates <= 34 weeks gestational age requiring respiratory support has been studied in four large previously conducted multicenter, double-blind, placebo-controlled clinical trials in total of 2,600 preterm infants. Of these, 1,290 received placebo, and 1,310 received inhaled nitric oxide at doses ranging from 5-20 ppm, for treatment periods of 7-24 days duration. The primary endpoint for these studies was alive and without BPD at 36 weeks postmenstrual age (PMA). The need for supplemental oxygen at 36 weeks PMA served as surrogate endpoint for the presence of BPD. Overall, efficacy for the prevention of bronchopulmonary dysplasia in preterm infants was not established. There were no meaningful differences between treatment groups with regard to overall deaths, methemoglobin levels, or adverse events commonly observed in premature infants, including intraventricular hemorrhage, patent ductus arteriosus, pulmonary hemorrhage, and retinopathy of prematurity.The use of GENOSYL (nitric oxide) for prevention of BPD in preterm neonates <=34 weeks gestational age is not recommended.

ADVERSE REACTIONS SECTION.

6 ADVERSE REACTIONS. The following adverse reactions are discussed elsewhere in the label;Hypoxemia [see Warnings and Precautions (5.2)] Worsening Heart Failure [see Warnings and Precautions (5.4)] The most common adverse reaction is hypotension (6).To report SUSPECTED ADVERSE REACTIONS, contact Vero Biotech at 1-877-337-4118 and http://www.vero-biotech.com/ or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.. 6.1Clinical Trials Experience. Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The adverse reaction information from the clinical studies does, however, provide basis for identifying the adverse events that appear to be related to drug use and for approximating rates.Controlled studies have included 325 patients on nitric oxide doses of to 80 ppm and 251 patients on placebo. Total mortality in the pooled trials was 11% on placebo and 9% on nitric oxide gas for inhalation, result adequate to exclude nitric oxide mortality being more than 40% worse than placebo.In both the NINOS and CINRGI studies, the duration of hospitalization was similar in nitric oxide gas for inhalation and placebo-treated groups.From all controlled studies, at least months of follow-up is available for 278 patients who received nitric oxide gas and 212 patients who received placebo. Among these patients, there was no evidence of an adverse effect of treatment on the need for re-hospitalization, special medical services, pulmonary disease, and neurological sequelae.In the NINOS study, treatment groups were similar with respect to the incidence and severity of intracranial hemorrhage, Grade IV hemorrhage, periventricular leukomalacia, cerebral infarction, seizures requiring anticonvulsant therapy, pulmonary hemorrhage, or gastrointestinal hemorrhage.In CINRGI, the only adverse reaction (>2% higher incidence on nitric oxide gas for inhalation than on placebo) was hypotension (14% vs. 11%).. 6.2 Post-Marketing Experience. Post marketing reports of accidental exposure to nitric oxide for inhalation in hospital staff have been associated with chest discomfort, dizziness, dry throat, dyspnea, and headache.

DESCRIPTION SECTION.

11 DESCRIPTION. GENOSYL (nitric oxide) is administered by inhalation. Nitric oxide is pulmonary vasodilator. Nitric oxide is generated from liquid dinitrogen tetroxide (N2O4) by the cassette in the GENOSYL Delivery System. Upon initiation of GENOSYL Delivery System, the liquid N2O4 is heated and the equilibrium shifts to nitrogen dioxide (NO2) gas. The NO2 is then converted into nitric oxide (NO) using the antioxidant cartridges, and nitric oxide is delivered to the patient by means of ventilator or nasal cannula. The amount of nitric oxide administered to the patient is set by controlling the temperature of the N2O4 liquid module, which controls the pressure inside the liquid module, which in turn controls the mass of NO2 that is sent to the primary cartridges, and hence the mass of nitric oxide. The mass flow of nitric oxide, together with the air from the pump, control the nitric oxide concentration. nitric oxide sensor monitors the nitric oxide in the patient line. GENOSYL Delivery System is designed to deliver controlled level of nitric oxide blended with breathing air or oxygen-enriched breathing air.The GENOSYL Delivery System controls the flow of nitric oxide mixed with air delivered to the patient.The structural formula of nitric oxide (NO) is shown below:.

GENOSYL(R) is indicated to improve oxygenation and reduce the need for extracorporeal membrane oxygenation in term and near-term (>34 weeks gestation) neonates with hypoxic respiratory failure associated with clinical or echocardiographic evidence of pulmonary hypertension in conjunction with ventilatory support and other appropriate agents.. GENOSYL is vasodilator indicated to improve oxygenation and reduce the need for extracorporeal membrane oxygenation in term and near-term (>34 weeks gestation) neonates with hypoxic respiratory failure associated with clinical or echocardiographic evidence of pulmonary hypertension in conjunction with ventilatory support and other appropriate agents (1).

MECHANISM OF ACTION SECTION.

12.1 Mechanism of Action. Nitric oxide relaxes vascular smooth muscle by binding to the heme moiety of cytosolic guanylate cyclase, activating guanylate cyclase and increasing intracellular levels of cyclic guanosine 3,5-monophosphate, which then leads to vasodilation. When inhaled, nitric oxide selectively dilates the pulmonary vasculature, and because of efficient scavenging by hemoglobin, has minimal effect on the systemic vasculature.GENOSYL appears to increase the partial pressure of arterial oxygen (PaO2) by dilating pulmonary vessels in better ventilated areas of the lung, redistributing pulmonary blood flow away from lung regions with low ventilation/perfusion (V/Q) ratios toward regions with normal ratios.

NONCLINICAL TOXICOLOGY SECTION.

13 NONCLINICAL TOXICOLOGY. 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. No evidence of carcinogenic effect was apparent, at inhalation exposures up to the recommended dose (20 ppm), in rats for 20 hr/day for up to two years. Higher exposures have not been investigated.Nitric oxide gas has demonstrated genotoxicity in Salmonella (Ames Test), human lymphocytes, and after in vivo exposure in rats. There are no animal or human studies to evaluate nitric oxide for effects on fertility.

OVERDOSAGE SECTION.

10 OVERDOSAGE. Overdosage with nitric oxide gas is manifest by elevations in methemoglobin and pulmonary toxicities associated with inspired NO2. Elevated NO2 may cause acute lung injury. Elevations in methemoglobin reduce the oxygen delivery capacity of the circulation. In clinical studies, NO2 levels >3 ppm or methemoglobin levels >7% were treated by reducing the dose of, or discontinuing, nitric oxide gas.Methemoglobinemia that does not resolve after reduction or discontinuation of therapy can be treated with intravenous vitamin C, intravenous methylene blue, or blood transfusion, based upon the clinical situation.

PHARMACODYNAMICS SECTION.

12.2 Pharmacodynamics. Effects on Pulmonary Vascular Tone in PPHNPersistent pulmonary hypertension of the newborn (PPHN) occurs as primary developmental defect or as condition secondary to other diseases such as meconium aspiration syndrome (MAS), pneumonia, sepsis, hyaline membrane disease, congenital diaphragmatic hernia (CDH), and pulmonary hypoplasia.

USE IN SPECIFIC POPULATIONS SECTION.

8 USE IN SPECIFIC POPULATIONS. 8.4 Pediatric Use. The safety and efficacy of nitric oxide for inhalation has been demonstrated in term and near-term neonates with hypoxic respiratory failure associated with evidence of pulmonary hypertension [see Clinical Studies (14.1)]. Additional studies conducted in premature neonates for the prevention of bronchopulmonary dysplasia have not demonstrated substantial evidence of efficacy [see Clinical Studies (14.3)]. No information about its effectiveness in other age populations is available.. 8.5 Geriatric Use. Nitric oxide is not indicated for use in the adult population.

WARNINGS AND PRECAUTIONS SECTION.

5 WARNINGS AND PRECAUTIONS. Rebound Pulmonary Hypertension: Abrupt discontinuation of GENOSYL may lead to worsening oxygenation and increasing pulmonary artery pressure (5.1).Methemoglobinemia: Methemoglobin increases with the dose of nitric oxide; following discontinuation or reduction of nitric oxide, methemoglobin levels return to baseline over period of hours (5.2).Elevated NO2 Levels: Monitor NO2 levels (5.3).Heart Failure: In patients with pre-existing left ventricular dysfunction, GENOSYL may increase pulmonary capillary wedge pressure leading to pulmonary edema (5.4).. 5.1 Rebound Pulmonary Hypertension Syndrome following Abrupt Discontinuation. Wean from GENOSYL [see Dosage and Administration (2.2)]. Abrupt discontinuation of GENOSYL may lead to worsening oxygenation and increasing pulmonary artery pressure, i.e., Rebound Pulmonary Hypertension Syndrome. Signs and symptoms of Rebound Pulmonary Hypertension Syndrome include hypoxemia, systemic hypotension, bradycardia, and decreased cardiac output. If Rebound Pulmonary Hypertension occurs, reinstate GENOSYL therapy immediately.. 5.2Hypoxemia from Methemoglobinemia. Nitric oxide combines with hemoglobin to form methemoglobin, which does not transport oxygen. Methemoglobin levels increase with the dose of GENOSYL; it can take hours or more before steady-state methemoglobin levels are attained. Monitor methemoglobin and adjust the dose of GENOSYL to optimize oxygenation.If methemoglobin levels do not resolve with decrease in dose or discontinuation of GENOSYL, additional therapy may be warranted to treat methemoglobinemia [see Overdosage (10)].. 5.3Airway Injury from Nitrogen Dioxide Nitrogen dioxide (NO2) forms in gas mixtures containing NO and O2. Nitrogen dioxide may cause airway inflammation and damage to lung tissues.If there is an unexpected change in NO2 concentration, or if the NO2 concentration reaches 0.5 ppm when measured in the breathing circuit, then the delivery system should be assessed in accordance with the GENOSYL Delivery System Operators Manual troubleshooting section, and the NO2 analyzer should be recalibrated. The dose of GENOSYL and/or FiO2 should be adjusted as appropriate.. 5.4Worsening Heart Failure. Patients with left ventricular dysfunction treated with GENOSYL may experience pulmonary edema, increased pulmonary capillary wedge pressure, worsening of left ventricular dysfunction, systemic hypotension, bradycardia and cardiac arrest. Discontinue GENOSYL while providing symptomatic care.
