Risk of BF-RhodoLED Lamp Induced Eye Injury [see Warnings and Precautions (5.3)].. Increased Photosensitivity [see Warnings and Precautions (5.4)].. Risk of Bleeding in Patients with Coagulation Disorders [see Warnings and Precautions (5.5)].. Ophthalmic Adverse Reactions [see Warnings and Precautions (5.6)].. Risk of Mucous Membrane Irritation [see Warnings and Precautions (5.7)].. Most common adverse reactions (>=10%) were application site erythema, pain/burning, irritation, edema, pruritus, exfoliation, scab, induration, and vesicles (6.1).To report SUSPECTED ADVERSE REACTIONS, contact Biofrontera Inc. at 1-844-829-7434 or FDA at 1-800-332-1088 or www.fda.gov/medwatch.. 6.1 Clinical Trial 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 clinical program for AMELUZ included three double-blind and placebo-controlled trials (Trials 1, 2, and 3), enrolling total of 299 subjects that were treated with narrow band light. Trial subjects were adults greater than or equal to 49 years of age, and the majority had Fitzpatrick skin type I, II, or III. No subjects had Fitzpatrick skin type or VI. Approximately 86% of subjects were male, and all subjects were Caucasian.For all trials, the enrolled subjects had mild to moderate AKs (Olsen grade and 2) with to lesions on the face and scalp. Overall, 87 placebo-treated subjects (n=16, n=32, n=39) and 212 AMELUZ-treated subjects (n=32, n=55, and n=125) were illuminated with BF-RhodoLED or similar narrow spectrum lamps.Local skin reactions at the application site were observed in about 99.5% of subjects treated with AMELUZ and narrow spectrum lamps. The most frequent adverse reactions during and after PDT were application site erythema, pain, burning, irritation, edema, pruritus, exfoliation, scab, induration, and vesicles.Most adverse reactions occurred during illumination or shortly afterwards, were generally of mild or moderate intensity, and lasted for to days in most cases; in some cases, however, they persisted for to weeks or even longer. Severe pain/burning occurred in up to 30% of subjects. In one case, the adverse reactions required interruption or discontinuation of the illumination.The incidence of common (>=1%, <10%) and very common (>=10%) adverse reactions in randomized, multicenter trials at the application site are presented in Table 1.Table 1: Incidence of Adverse Reactions Occurring at >=1% of the AMELUZ Group and More Frequently than the Vehicle Group in the Actinic Keratosis Trials at the Application SiteAdverse reactionVehiclen=87AMELUZn=212Adverse reactions at theapplication siteErythemaPain/BurningIrritationEdemaPruritusExfoliationScabIndurationVesiclesParesthesiaHyperalgesiaReactionDiscomfortErosionDischargeBleedingPustules34 (39%)26 (30%)17 (20%)3 (3%)14 (16%)4 (5%)2 (2%)0 (0%)1 (1%)2 (2%)0 (0%)2 (2%)0 (0%)0 (0%)0 (0%)0 (0%)0 (0%)195 (92%)195 (92%)153 (72%)75 (35%)72 (34%)41 (19%)41 (19%)26 (12%)25 (12%)18 (9%)13 (6%)8 (4%)7 (3%)6 (3%)4 (2%)3 (1%)3 (1%)Common (>=1%, <10%) adverse reactions not at the application site for AMELUZ were headache, skin exfoliation, chills and eyelid edema.Less common (>=0.1%, <1%) adverse reactions at the application site for AMELUZ were hemorrhage and swelling. The adverse reactions not at the application site were blister, feeling hot, pruritus, pyrexia, scab, nervousness, pain, petechiae, rash pustular, skin erosion and ulcer.In clinical trial designed to investigate the sensitization potential of aminolevulinic acid with 216 healthy subjects, 13 subjects (6%) developed allergic contact dermatitis after continuous exposure for 21 days with doses of aminolevulinic acid that were higher than doses normally used in the treatment of AK.. 6.2 Postmarketing Experience.

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.


13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. Long-term studies to evaluate the carcinogenic potential of AMELUZ or aminolevulinic acid have not been performed.Aminolevulinic acid revealed no evidence of mutagenic or clastogenic potential based on the results of three in vitro genotoxicity tests (Ames assay, HPRT test in V79 cells, and Human lymphocyte chromosomal aberration assay) and one in vivo genotoxicity test (mouse micronucleus assay). These genotoxicity studies were conducted without exposure to light. There is literature report that indicates that aminolevulinic acid may cause genotoxic effects in the presence and in the absence of activating light. These genotoxic effects are likely caused by the formation of reactive oxygen species.Animal fertility studies have not been conducted with aminolevulinic acid because of the negligible systemic absorption of aminolevulinic acid in humans following topical administration of AMELUZ under maximal clinical use conditions.

CLINICAL PHARMACOLOGY SECTION.


12. CLINICAL PHARMACOLOGY. 12.1 Mechanism of Action. Photoactivation following topical application of AMELUZ occurs when aminolevulinic acid (prodrug) is metabolized to protoporphyrin IX (PpIX), photoactive compound which accumulates in the skin. When exposed to red light of suitable wavelength and energy, PpIX is activated resulting in an excited state of porphyrin molecules. In the presence of oxygen, reactive oxygen species are formed which causes damage to cellular components, and eventually destroys the cells. AMELUZ photodynamic therapy of AK lesions utilizes photoactivation of topically applied AMELUZ resulting from BF-RhodoLED illumination, which provides red light of narrow spectrum and light dose of approximately 37 J/cm2.. 12.2 Pharmacodynamics. The pharmacodynamics of AMELUZ in the treatment of actinic keratosis are unknown.. 12.3 Pharmacokinetics Pharmacokinetics (PK) of aminolevulinic acid and PpIX was evaluated in trial of 12 adult subjects with mild to moderate AK with at least 10 AK lesions on the face or forehead. single dose of one entire tube of AMELUZ (2 grams) was applied under occlusion for hours followed by PDT to total area of 20 cm2. The mean +- SD baseline plasma aminolevulinic acid and PpIX concentrations were 20.16 +- 16.53 ng/mL and 3.27 +- 2.40 ng/mL, respectively. In most subjects, an up to 2.5-fold increase of aminolevulinic acid plasma concentrations was observed during the first hours after AMELUZ application. The mean +- SD area under the concentration time curve (AUC0-t) and maximum concentration (Cmax) for baseline corrected aminolevulinic acid (n=12) were 142.83 +- 75.50 ng.h/mL and 27.19 +- 20.02 ng/mL, respectively. The median Tmax (time at which Cmax occurred) was hours.The majority (about 55%) of the PpIX concentrations were below the limit of quantification (LOQ 1 ng/mL) and baseline corrected values were negative in all subjects except for one. The baseline corrected AUC0-t and Cmax in the single subject was 0.07 ng.h/mL and 0.29 ng/mL, respectively. PK of aminolevulinic acid and PpIX following treatment on the scalp was not evaluated.

CLINICAL STUDIES SECTION.


14. CLINICAL STUDIES. The efficacy and safety of AMELUZ in combination with PDT using narrow spectrum (red light lamp) source were evaluated in three randomized, multicenter trials (Trials 1, 2, and 3). Trials and were vehicle-controlled and double-blind. Trial was double-blind with respect to vehicle and observer-blind regarding the active comparator arm. All clinical trials included follow-up assessment after and 12 months.In these trials, 212 subjects with to mild to moderate AK lesions on the face/forehead and/or bald scalp were treated with AMELUZ and narrow band spectrum lamp. Subjects ranged from 49 to 87 years of age (mean 71 years), and 92% had Fitzpatrick skin type I, II, or III. No subjects had Fitzpatrick skin type or VI. Approximately 86% of subjects were male, and all subjects were Caucasian.All sessions were comprised of lesion preparation to roughen the surface and remove crusts, application of AMELUZ with occlusion for hours, and removal of the residual gel. Subsequently, the entire treatment area was illuminated with narrow spectrum red light source, lamp of either 630 nm or 633 nm and light dose of approximately 37 J/cm2. In Trial 3, illumination was performed with BF-RhodoLED, red light source with narrow spectrum around 635 nm and light dose of approximately 37 J/cm2.In all trials, the lesions that were not completely cleared 12 weeks after the initial treatment were treated second time with an identical regimen. In the trials, 42% (88/212) of subjects needed second treatment.The primary endpoint for all trials was complete clearance 12 weeks after the last PDT. The results of Trials 1, and are presented in Table 2.Table 2: Complete Clearance 12 Weeks After the Last Narrow Spectrum PDT in Subjects with Actinic KeratosesAMELUZVehicleTrial 1106/125 (85%)5/39 (13%)Trial 227/32 (84%)2/16 (13%)Trial 350/55 (91%)7/32 (22%)Subjects who achieved complete clearance at 12 weeks after the last PDT entered 12-month follow-up period. In the three trials, subjects who received AMELUZ with the narrowband PDT and achieved complete clearance 12 weeks after the last PDT had recurrence rates of 14%, 11%, and 25%, respectively (at months) and 40%, 22%, and 37%, respectively (at 12 months).Recurrence was defined as the percentage of subjects with at least one recurrent lesion during the 6-month or 12-month follow-up period in subjects with completely cleared lesions 12 weeks after the last PDT.In clinical trial designed to investigate the sensitization potential of aminolevulinic acid hydrochloride with 216 healthy subjects, 13 subjects (6%) developed allergic contact dermatitis after continuous exposure for 21 days with doses of aminolevulinic acid hydrochloride that were higher than doses normally used in the treatment of AK.

Retreat lesions that have not completely resolved after months after the initial treatment.Refer to BF-RhodoLED user manual for detailed lamp safety and operating instructions. Both patient and medical personnel conducting the PDT should adhere to all safety instructions.. 2.2 Dosage and Administration Instructions. PDT is multi-stage process:Step 1. Preparation of LesionsBefore applying AMELUZ, carefully wipe all lesions with an ethanol or isopropanol-soaked cotton pad to ensure degreasing of the skin. Figure 1A: Degreasing the skinThereafter, remove any scaling and crusts and gently roughen all lesion surfaces, taking care to avoid bleeding. Figure 1B: Removal of scales and crustStep 2. Application of AMELUZUse glove protected fingertips or spatula to apply AMELUZ. Apply gel approximately mm thick and include approximately mm of the surrounding skin. Use sufficient amount of gel to cover the single lesions or if multiple lesions, the entire area. Application area should not exceed 20 cm2 and no more than grams of AMELUZ (one tube) should be used at one time. The gel can be applied to healthy skin around the lesions. Avoid application near mucous membranes such as the eyes, nostrils, mouth, and ears (keep distance of cm from these areas). In case of accidental contact with these areas, thoroughly rinse with water. Allow the gel to dry for approximately 10 minutes before applying occlusive dressing. Figure 2: Drug applicationStep 3. Occlusion for HoursCover the area where the gel has been applied with light-blocking, occlusive dressing. Following hours of occlusion, remove the dressing and wipe off any remaining gel. Figure 3: OcclusionStep 4. Illumination with Red LightDuring illumination, patient and medical personnel need to wear suitable protective eyewear.Immediately after removing occlusion and any remaining gel, illuminate the treatment area with BF-RhodoLED(R), red light source with narrow spectrum around 635 nm that delivers light dose of approximately 37 J/cm2 within 10 minutes. Calibration by the operator is not needed; the illumination time is calculated automatically. Position the lamp head 5-8 cm from the skins surface. When an area of x 18 cm is illuminated, the effective treatment area is x16 cm. Larger areas can be illuminated in several steps.Healthy untreated skin surrounding the AK lesions does not need protection during illumination. Figure 4: IlluminationIf for any reason, the lesions cannot be illuminated within hours after AMELUZ application, rinse off the gel with saline and water. For days, protect the lesion sites and surrounding skin from sunlight or prolonged or intense light (e.g., tanning beds, sun lamps).. Figure 1A: Degreasing of the skin.
