PHARMACODYNAMICS SECTION.


12.2 Pharmacodynamics. Dose TitrationIn Trial 1, ALP reduction was observed to plateau at approximately months in most patients treated with OCALIVA mg once daily. Increasing the dosage of OCALIVA to 10 mg once daily based on tolerability and response provided additional reduction in ALP in the majority of patients [see Dosage and Administration (2.2), Clinical Studies (14)].. Pharmacodynamic MarkersIn Trial 1, administration of OCALIVA 10 mg once daily was associated with 173% increase in concentrations of FGF-19, an FXR-inducible enterokine involved in bile acid homeostasis, from baseline to Month 12. Concentrations of cholic acid and chenodeoxycholic acid were reduced 2.7 micromolar and 1.4 micromolar, respectively, from baseline to Month 12. The clinical relevance of these findings is unknown. Cardiac ElectrophysiologyAt dose of 10-times the maximum recommended dose, OCALIVA does not prolong the QT interval to any clinically relevant extent.

PHARMACOKINETICS SECTION.


12.3 Pharmacokinetics. AbsorptionFollowing multiple oral doses of OCALIVA 10 mg once daily, peak plasma concentrations (Cmax) of obeticholic acid occurred at median time (Tmax) of approximately 1.5 hours. The median Tmax for both the glyco- and tauro-conjugates of obeticholic acid was 10 hours. Coadministration with food did not alter the extent of absorption of obeticholic acid [see Dosage and Administration (2.5)]. Following multiple-dose administration of OCALIVA 5, 10, and 25 mg once daily (2.5-times the highest recommend dosage) for 14 days, systemic exposures of obeticholic acid increased dose proportionally. Exposures to glyco-obeticholic acid and tauro-obeticholic acid, and total obeticholic acid (the sum of obeticholic acid and its two active conjugates) increased more than proportionally with dose. The steady-state systemic exposure (AUC0-24h) achieved on Day 14 of total obeticholic acid was 4.2-, 6.6-, and 7.8- fold the systemic exposure (AUC0-24h) achieved on Day after 5, 10, and 25 mg once daily dosing, respectively.. DistributionHuman plasma protein binding of obeticholic acid and its conjugates is greater than 99%. The volume of distribution of obeticholic acid is 618 L. The volumes of distribution of glyco- and tauro-obeticholic acid have not been determined.. Elimination. MetabolismObeticholic acid is conjugated with glycine or taurine in the liver and secreted into bile. These glycine and taurine conjugates of obeticholic acid are absorbed in the small intestine leading to enterohepatic recirculation. The conjugates can be deconjugated in the ileum and colon by intestinal microbiota, leading to the conversion to obeticholic acid that can be reabsorbed or excreted in feces, the principal route of elimination.After daily administration of obeticholic acid, there was accumulation of the glycine and taurine conjugates of obeticholic acid, which have in vitro pharmacological activities similar to the parent drug, obeticholic acid. The metabolite-to-parent ratios of the glycine and taurine conjugates of obeticholic acid were 13.8 and 12.3 respectively, after daily administration. An additional third obeticholic acid metabolite, 3-glucuronide, was formed but was considered to have minimal pharmacologic activity.. ExcretionAfter administration of radiolabeled obeticholic acid, about 87% of the dose was excreted in feces through biliary secretion. Less than 3% of the dose was excreted in the urine with no detection of obeticholic acid.. Specific Populations. Body weight, Age, Sex Race/Ethnicity: Based on population pharmacokinetic analysis, body weight was significant predictor of obeticholic acid pharmacokinetics with lower obeticholic acid exposure expected with higher body weight. The body weight effect is not expected to cause meaningful impact on efficacy. The pharmacokinetics of obeticholic acid would not be expected to be altered based on age, sex, or race/ethnicity.. Renal Impairment: Obeticholic acid has not been studied in patients with moderate and severe renal impairment (estimated glomerular filtration rate [eGFR] less than 60 mL/min/1.73 m2). In the population pharmacokinetic analysis, an eGFR greater than 50 mL/min/1.73 m2 did not have meaningful effect on the pharmacokinetics of obeticholic acid and its conjugated metabolites. Hepatic Impairment: Obeticholic acid is metabolized in the liver. In subjects with mild, moderate, and severe hepatic impairment (Child-Pugh Class A, B, and C, respectively), the mean AUC of total obeticholic acid increased 1.1-, 4- and 17-fold, respectively, compared to subjects with normal hepatic function following single-dose administration of 10 mg OCALIVA [see Contraindications (4), Warnings and Precautions (5.1), Use in Specific Populations (8.6)]. Drug Interaction Studies. Effect of Obeticholic Acid on Other DrugsBased on in vitro studies, obeticholic acid can inhibit CYP3A4. However, an in vivo study indicated no inhibition of CYP3A4 by obeticholic acid at the recommended dose of OCALIVA. Obeticholic acid is not expected to inhibit CYPs 2B6, 2C8, 2C9, 2C19, and 2D6, or induce CYPs 1A2, 2B6, 2C8, 2C9, 2C19, and 3A4 at the recommended dose of OCALIVA. Down-regulation of mRNA was observed in concentration-dependent fashion for CYP1A2 and CYP3A4 by obeticholic acid and its glycine and taurine conjugates.In vitro studies suggest that there is potential for obeticholic acid and its glycine and taurine conjugates to inhibit OATP1B1 and OATP1B3 (the clinical significance of which is unknown), but not P-gp, BCRP, OAT1, OAT3, OCT2, and MATE transporters, at the recommended dose of OCALIVA.In vitro studies showed that obeticholic acid and its glycine and taurine conjugates inhibit BSEP in dose dependent manner. However, an in vivo drug interaction due to inhibition of BSEP in patients using the recommended dosage regimen appears unlikely. Induction of BSEP can occur by FXR activation by obeticholic acid and its conjugates, which are FXR agonists.. Warfarin: Concomitant administration of 25 mg warfarin as single dose with OCALIVA 10 mg once daily resulted in 13% increase in systemic exposure to S-warfarin and 11% decrease in maximum INR [see Drug Interactions (7.2)]. Caffeine (CYP1A2 substrate): Concomitant administration of 200 mg caffeine as single dose with OCALIVA 10 mg once daily resulted in 42% increase in plasma AUC and 6% increase in Cmax of caffeine [see Drug Interactions (7.3)]. Omeprazole (CYP2C19 substrate): Concomitant administration of 20 mg omeprazole as single dose with OCALIVA 10 mg once daily resulted in 32% increase in AUC and 33% increase in Cmax of omeprazole. The clinical significance is unknown.No clinically relevant interactions were seen when the following drugs were administered as single doses concomitantly with OCALIVA 10 mg once daily:. Midazolam mg (CYP3A4 substrate): 2% increase in AUC and Cmax of midazolam. Dextromethorphan 30 mg (CYP2D6 substrate): 11% decrease in AUC and 12% decrease in Cmax of dextromethorphan.. Digoxin 0.25 mg (P-gp substrate): 1% increase in AUC and 3% decrease in Cmax of digoxin.. Rosuvastatin 20 mg (BCRP, OATP1B1, OATP1B3 substrate): 22% increase in AUC and 27% increase in Cmax of rosuvastatin. Effect of Other Drugs on Obeticholic Acid In vitro data suggest that obeticholic acid is not metabolized to any significant extent by CYP450 enzymes.. Proton Pump Inhibitors (omeprazole): Concomitant administration of 20 mg omeprazole once daily with OCALIVA 10 mg once daily resulted in less than 1.2-fold increase in obeticholic acid exposure. This increase is not expected to be clinically relevant. Concomitant administration of 40 mg omeprazole once daily with OCALIVA 10 mg once daily was not studied.. BSEP inhibitors: In vitro data indicate that tauro-obeticholic acid is substrate of BSEP [see Drug Interactions (7.4)].

6 ADVERSE REACTIONS. The following clinically significant adverse reactions are described elsewhere in labeling:Hepatic Decompensation and Failure in PBC Patients with Cirrhosis [see Warnings and Precautions (5.1)] Severe Pruritus [see Warnings and Precautions (5.2)] Reduction in HDL-C [see Warnings and Precautions (5.3)] Hepatic Decompensation and Failure in PBC Patients with Cirrhosis [see Warnings and Precautions (5.1)] Severe Pruritus [see Warnings and Precautions (5.2)] Reduction in HDL-C [see Warnings and Precautions (5.3)] Most common adverse reactions (>= 5%) are: pruritus, fatigue, abdominal pain and discomfort, rash, oropharyngeal pain, dizziness, constipation, arthralgia, thyroid function abnormality, and eczema.

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.A total of 432 patients with PBC were studied in three double-blind, placebo-controlled clinical trials. Of these patients, 290 were treated with OCALIVA for at least months, 232 were treated for at least 12 months, and 70 were treated for at least years. There were 131 patients who received OCALIVA 10 mg once daily and 70 who received OCALIVA mg once daily.In Trial 1, 216 patients were randomized (1:1:1) to receive either:OCALIVA 10 mg once daily for the entire 12 months of the trial (n=73) OCALIVA titration (5 mg once daily for the initial months, with the option to increase to 10 mg once daily for the last months, in patients who were tolerating OCALIVA, but had ALP 1.67-times ULN or greater, and/or total bilirubin greater than ULN, or less than 15% ALP reduction) (n=70); orplacebo (n=73).During the trial, OCALIVA or placebo was administered in combination with UDCA in 93% of patients and as monotherapy in 7% of patients who were unable to tolerate UDCA. The overall discontinuation rate was 12% in the OCALIVA 10 mg arm, 10% in the OCALIVA titration arm, and 4% in the placebo arm.The recommended starting dosage of OCALIVA is mg orally once daily for months with titration to 10 mg once daily based upon tolerability and response [see Dosage and Administration (2.2)]. Initiation of therapy with OCALIVA 10 mg once daily is not recommended due to an increased risk of pruritus. The most common adverse reactions in Trial occurring in at least 5% of patients in either OCALIVA treatment arm and at an incidence at least 1% higher than the placebo treatment arm are shown in Table 1.Table 1:Most Common Adverse Reactions in Adult Patients with PBC in Trial by Treatment Arm with or without UDCAIn the trial there were 16 patients (7%) who were intolerant and did not receive concomitant UDCA: patients (8%) in the OCALIVA 10 mg arm, patients (7%) in the OCALIVA titration arm, and patients (7%) in the placebo arm.

OCALIVA 10 mg once daily for the entire 12 months of the trial (n=73) OCALIVA titration (5 mg once daily for the initial months, with the option to increase to 10 mg once daily for the last months, in patients who were tolerating OCALIVA, but had ALP 1.67-times ULN or greater, and/or total bilirubin greater than ULN, or less than 15% ALP reduction) (n=70); or. placebo (n=73).. Hepatic Adverse ReactionsIn Trial 1, the following serious or otherwise clinically significant hepatic adverse reactions were reported at the recommended dosage of OCALIVA: one patient in the OCALIVA 10 mg treatment arm experienced ascites; one patient in the OCALIVA titration treatment arm experienced two episodes of ascites and four episodes of hepatic encephalopathy; one patient in the placebo treatment arm experienced variceal bleeding.. PruritusApproximately 60% of patients had history of pruritus upon enrollment in Trial 1. Treatment-emergent pruritus, including all the terms described in Table 1, generally started within the first month following the initiation of treatment with OCALIVA.The incidence of pruritus was higher in patients who started on OCALIVA 10 mg once daily relative to the OCALIVA titration arm, 70% and 56%, respectively. Discontinuation rates due to pruritus were also higher in patients who started on OCALIVA 10 mg once daily relative to the OCALIVA titration arm, 10% and 1%, respectively.The number of patients with pruritus who required an intervention (e.g., dosage adjustment, treatment interruption, or initiation of bile acid binding resin or antihistamine) was 30 of 51 patients (59%) in the OCALIVA 10 mg arm, 24 of 39 patients (62%) in the OCALIVA titration arm, and 14 of 28 patients (50%) in the placebo arm.. 6.2 Postmarketing Experience. The following adverse reactions have been identified during post-approval use of OCALIVA. Because these reactions are reported voluntarily from population of uncertain size, it is not always possible to reliably estimate their frequency or establish causal relationship to drug exposure, particularly in PBC patients who have progressive liver disease.. Hepatobiliary Disorders: liver failure, new onset cirrhosis, increased direct and total bilirubin, new or worsening of jaundice [see Warnings and Precautions (5.1)].

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.


13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. Carcinogenic potential of obeticholic acid was assessed in carcinogenicity studies of up to years in duration in mice and rats. In mice, there were no drug-related neoplastic findings at doses up to 25 mg/kg/day obeticholic acid, dose that produced systemic exposures approximately 12-times those in humans at the MRHD of 10 mg. In rats, obeticholic acid was administered at doses of 2, 7, and 20 mg/kg/day. At 20 mg/kg/day (approximately 12-times the human exposure at the MRHD), obeticholic acid caused an increase in the incidence of benign granulosa cell tumors in the ovaries and benign granular cell tumors in the cervix and vagina of female rats. There were no drug-related neoplastic findings in male rats. Obeticholic acid was not genotoxic in the Ames test, human peripheral blood lymphocyte chromosomal aberration test, and mouse micronucleus test. The glycine conjugate of obeticholic acid was also not genotoxic in an Ames test and human peripheral blood lymphocyte chromosome aberration test. The taurine conjugate of obeticholic acid was not genotoxic in an Ames test, and was negative in human peripheral blood lymphocyte chromosomal aberration test in the presence of metabolic activation; the findings of the chromosomal aberration assay in the absence of metabolic activation were inconclusive.Obeticholic acid, administered at oral doses of 5, 25, and 50 mg/kg/day to male rats for 28 days before mating and throughout the mating period, and to female rats from 14 days before mating through mating and until gestation day 7, did not alter male or female fertility or early embryonic development at any dose (the 50 mg/kg/day dose is approximately 13-times the human exposure at the MRHD).

CLINICAL PHARMACOLOGY SECTION.


12 CLINICAL PHARMACOLOGY. 12.1 Mechanism of Action. Obeticholic acid is an agonist for FXR, nuclear receptor expressed in the liver and intestine. FXR is key regulator of bile acid, inflammatory, fibrotic, and metabolic pathways. FXR activation decreases the intracellular hepatocyte concentrations of bile acids by suppressing de novo synthesis from cholesterol as well as by increased transport of bile acids out of the hepatocytes. These mechanisms limit the overall size of the circulating bile acid pool while promoting choleresis, thus reducing hepatic exposure to bile acids.. 12.2 Pharmacodynamics. Dose TitrationIn Trial 1, ALP reduction was observed to plateau at approximately months in most patients treated with OCALIVA mg once daily. Increasing the dosage of OCALIVA to 10 mg once daily based on tolerability and response provided additional reduction in ALP in the majority of patients [see Dosage and Administration (2.2), Clinical Studies (14)].. Pharmacodynamic MarkersIn Trial 1, administration of OCALIVA 10 mg once daily was associated with 173% increase in concentrations of FGF-19, an FXR-inducible enterokine involved in bile acid homeostasis, from baseline to Month 12. Concentrations of cholic acid and chenodeoxycholic acid were reduced 2.7 micromolar and 1.4 micromolar, respectively, from baseline to Month 12. The clinical relevance of these findings is unknown. Cardiac ElectrophysiologyAt dose of 10-times the maximum recommended dose, OCALIVA does not prolong the QT interval to any clinically relevant extent.. 12.3 Pharmacokinetics. AbsorptionFollowing multiple oral doses of OCALIVA 10 mg once daily, peak plasma concentrations (Cmax) of obeticholic acid occurred at median time (Tmax) of approximately 1.5 hours. The median Tmax for both the glyco- and tauro-conjugates of obeticholic acid was 10 hours. Coadministration with food did not alter the extent of absorption of obeticholic acid [see Dosage and Administration (2.5)]. Following multiple-dose administration of OCALIVA 5, 10, and 25 mg once daily (2.5-times the highest recommend dosage) for 14 days, systemic exposures of obeticholic acid increased dose proportionally. Exposures to glyco-obeticholic acid and tauro-obeticholic acid, and total obeticholic acid (the sum of obeticholic acid and its two active conjugates) increased more than proportionally with dose. The steady-state systemic exposure (AUC0-24h) achieved on Day 14 of total obeticholic acid was 4.2-, 6.6-, and 7.8- fold the systemic exposure (AUC0-24h) achieved on Day after 5, 10, and 25 mg once daily dosing, respectively.. DistributionHuman plasma protein binding of obeticholic acid and its conjugates is greater than 99%. The volume of distribution of obeticholic acid is 618 L. The volumes of distribution of glyco- and tauro-obeticholic acid have not been determined.. Elimination. MetabolismObeticholic acid is conjugated with glycine or taurine in the liver and secreted into bile. These glycine and taurine conjugates of obeticholic acid are absorbed in the small intestine leading to enterohepatic recirculation. The conjugates can be deconjugated in the ileum and colon by intestinal microbiota, leading to the conversion to obeticholic acid that can be reabsorbed or excreted in feces, the principal route of elimination.After daily administration of obeticholic acid, there was accumulation of the glycine and taurine conjugates of obeticholic acid, which have in vitro pharmacological activities similar to the parent drug, obeticholic acid. The metabolite-to-parent ratios of the glycine and taurine conjugates of obeticholic acid were 13.8 and 12.3 respectively, after daily administration. An additional third obeticholic acid metabolite, 3-glucuronide, was formed but was considered to have minimal pharmacologic activity.. ExcretionAfter administration of radiolabeled obeticholic acid, about 87% of the dose was excreted in feces through biliary secretion. Less than 3% of the dose was excreted in the urine with no detection of obeticholic acid.. Specific Populations. Body weight, Age, Sex Race/Ethnicity: Based on population pharmacokinetic analysis, body weight was significant predictor of obeticholic acid pharmacokinetics with lower obeticholic acid exposure expected with higher body weight. The body weight effect is not expected to cause meaningful impact on efficacy. The pharmacokinetics of obeticholic acid would not be expected to be altered based on age, sex, or race/ethnicity.. Renal Impairment: Obeticholic acid has not been studied in patients with moderate and severe renal impairment (estimated glomerular filtration rate [eGFR] less than 60 mL/min/1.73 m2). In the population pharmacokinetic analysis, an eGFR greater than 50 mL/min/1.73 m2 did not have meaningful effect on the pharmacokinetics of obeticholic acid and its conjugated metabolites. Hepatic Impairment: Obeticholic acid is metabolized in the liver. In subjects with mild, moderate, and severe hepatic impairment (Child-Pugh Class A, B, and C, respectively), the mean AUC of total obeticholic acid increased 1.1-, 4- and 17-fold, respectively, compared to subjects with normal hepatic function following single-dose administration of 10 mg OCALIVA [see Contraindications (4), Warnings and Precautions (5.1), Use in Specific Populations (8.6)]. Drug Interaction Studies. Effect of Obeticholic Acid on Other DrugsBased on in vitro studies, obeticholic acid can inhibit CYP3A4. However, an in vivo study indicated no inhibition of CYP3A4 by obeticholic acid at the recommended dose of OCALIVA. Obeticholic acid is not expected to inhibit CYPs 2B6, 2C8, 2C9, 2C19, and 2D6, or induce CYPs 1A2, 2B6, 2C8, 2C9, 2C19, and 3A4 at the recommended dose of OCALIVA. Down-regulation of mRNA was observed in concentration-dependent fashion for CYP1A2 and CYP3A4 by obeticholic acid and its glycine and taurine conjugates.In vitro studies suggest that there is potential for obeticholic acid and its glycine and taurine conjugates to inhibit OATP1B1 and OATP1B3 (the clinical significance of which is unknown), but not P-gp, BCRP, OAT1, OAT3, OCT2, and MATE transporters, at the recommended dose of OCALIVA.In vitro studies showed that obeticholic acid and its glycine and taurine conjugates inhibit BSEP in dose dependent manner. However, an in vivo drug interaction due to inhibition of BSEP in patients using the recommended dosage regimen appears unlikely. Induction of BSEP can occur by FXR activation by obeticholic acid and its conjugates, which are FXR agonists.. Warfarin: Concomitant administration of 25 mg warfarin as single dose with OCALIVA 10 mg once daily resulted in 13% increase in systemic exposure to S-warfarin and 11% decrease in maximum INR [see Drug Interactions (7.2)]. Caffeine (CYP1A2 substrate): Concomitant administration of 200 mg caffeine as single dose with OCALIVA 10 mg once daily resulted in 42% increase in plasma AUC and 6% increase in Cmax of caffeine [see Drug Interactions (7.3)]. Omeprazole (CYP2C19 substrate): Concomitant administration of 20 mg omeprazole as single dose with OCALIVA 10 mg once daily resulted in 32% increase in AUC and 33% increase in Cmax of omeprazole. The clinical significance is unknown.No clinically relevant interactions were seen when the following drugs were administered as single doses concomitantly with OCALIVA 10 mg once daily:. Midazolam mg (CYP3A4 substrate): 2% increase in AUC and Cmax of midazolam. Dextromethorphan 30 mg (CYP2D6 substrate): 11% decrease in AUC and 12% decrease in Cmax of dextromethorphan.. Digoxin 0.25 mg (P-gp substrate): 1% increase in AUC and 3% decrease in Cmax of digoxin.. Rosuvastatin 20 mg (BCRP, OATP1B1, OATP1B3 substrate): 22% increase in AUC and 27% increase in Cmax of rosuvastatin. Effect of Other Drugs on Obeticholic Acid In vitro data suggest that obeticholic acid is not metabolized to any significant extent by CYP450 enzymes.. Proton Pump Inhibitors (omeprazole): Concomitant administration of 20 mg omeprazole once daily with OCALIVA 10 mg once daily resulted in less than 1.2-fold increase in obeticholic acid exposure. This increase is not expected to be clinically relevant. Concomitant administration of 40 mg omeprazole once daily with OCALIVA 10 mg once daily was not studied.. BSEP inhibitors: In vitro data indicate that tauro-obeticholic acid is substrate of BSEP [see Drug Interactions (7.4)].

CLINICAL STUDIES SECTION.


14 CLINICAL STUDIES. The recommended starting dosage of OCALIVA is mg orally once daily for months with titration to 10 mg once daily based upon tolerability and response [see Dosage and Administration (2.2)]. Initiation of therapy with starting dosage OCALIVA 10 mg once daily is not recommended due to an increased risk of pruritus [see Adverse Reactions (6.1)]. Trial was randomized, double-blind, placebo-controlled, 12-month clinical trial which evaluated the safety and efficacy of OCALIVA in 216 patients with PBC who were taking UDCA for at least 12 months (on stable dosage for at least months), or who were unable to tolerate UDCA and did not receive UDCA for at least months. Patients were included in the trial if the ALP was 1.67-times upper limit of normal (ULN) or greater and/or if total bilirubin was greater than 1-times ULN but less than 2-times ULN. Patients were excluded from the trial if they had other liver disease, presence of clinically significant hepatic decompensation events (i.e., portal hypertension and its complications, cirrhosis with complications, or hepato-renal syndrome), severe pruritus, or Model for End Stage Liver Disease (MELD) score of 15 or greater. Patients were randomized (1:1:1) to receive either OCALIVA 10 mg once daily for the entire 12 months of the trial, (n=73); OCALIVA titration (5 mg once daily for the initial months, with the option to increase to 10 mg once daily for the last months if the patient was tolerating OCALIVA but had ALP 1.67-times ULN or greater, and/or total bilirubin greater than ULN, or less than 15% ALP reduction) (n=70); or placebo (n=73). OCALIVA or placebo was administered in combination with UDCA in 93% of patients during the trial and as monotherapy in 7% of patients who were unable to tolerate UDCA.The primary endpoint was responder analysis at Month 12, where response was defined as composite of three criteria: ALP less than 1.67-times the ULN, total bilirubin less than or equal to ULN, and an ALP decrease of at least 15%. The ULN for ALP was defined as 118 U/L for females and 124 U/L for males. The ULN for total bilirubin was defined as 1.1 mg/dL for females and 1.5 mg/dL for males.The study population was 91% female and 94% white. The mean age was 56 years (range 29 to 86 years). The mean baseline ALP concentration was 323.2 U/L, corresponding to 2.74-times ULN. Approximately 29% of the patients had ALP concentration levels greater than 3-times the ULN. The mean baseline total bilirubin concentration was 0.65 mg/dL and was less than or equal to the ULN in 92% of the enrolled patients. Distribution of patients by Rotterdam disease stage criteria at baseline is shown in Table 2. Cirrhosis was present at baseline in patients (5%) in the OCALIVA 10 mg arm, patients (10%) in the OCALIVA titration arm, and patients (12%) in the placebo arm.Table 2:Rotterdam Disease Stage Criteria at Baseline in Trial by Treatment Arm with or without UDCA In the trial, there were 16 patients (7%) who were intolerant and did not receive concomitant UDCA: patients (8%) in the OCALIVA 10 mg arm, patients (7%) in the OCALIVA titration arm, and patients (7%) in the placebo arm.

Mean Reduction in ALPFigure shows the mean reductions in ALP in OCALIVA-treated patients compared to placebo. Reductions were observed as early as Week 2, plateaued by Month and were maintained through Month 12 for patients who were maintained on the same dosage throughout 12 months. Although Trial studied titration at months, these data are supportive of titration of OCALIVA after months [see Dosage and Administration (2.2)]. For patients in the OCALIVA titration arm whose OCALIVA dosage was increased from mg once daily to 10 mg once daily, additional reductions in ALP were observed at Month 12 in the majority of patients [see Clinical Pharmacology (12.2)]. Figure 1:Mean ALP over 12 Months in Trial by Treatment Arm with or without UDCAa aIn the trial there were 16 patients (7%) who were intolerant and did not receive concomitant UDCA: patients (8%) in the OCALIVA 10 mg arm, patients (7%) in the OCALIVA titration arm, and patients (7%) in the placebo arm.bPatients randomized to OCALIVA titration received OCALIVA mg once daily for the initial 6-month period. At Month 6, patients who were tolerating OCALIVA, but had an ALP 1.67-times ULN or greater, and/or total bilirubin greater than ULN, or less than 15% ALP reduction were eligible for titration from mg once daily to 10 mg once daily for the final months of the trial..

OCALIVA MonotherapyFifty-one PBC patients with baseline ALP 1.67-times ULN or greater and/or total bilirubin greater than ULN were evaluated for biochemical response to OCALIVA as monotherapy (24 patients received OCALIVA 10 mg once daily and 27 patients received placebo) in pooled analysis of data from Trial and from randomized, double-blind, placebo-controlled, 3-month clinical trial. At Month 3, (38%) OCALIVA-treated patients achieved response to the composite endpoint, compared to (4%) placebo-treated patient. The mean (95% CI) reduction in ALP in OCALIVA-treated patients was 246 (165, 327) U/L compared to an increase of 17 (-7, 42) U/L in the placebo-treated patients.

CLINICAL TRIALS EXPERIENCE SECTION.


6.1 Clinical 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.A total of 432 patients with PBC were studied in three double-blind, placebo-controlled clinical trials. Of these patients, 290 were treated with OCALIVA for at least months, 232 were treated for at least 12 months, and 70 were treated for at least years. There were 131 patients who received OCALIVA 10 mg once daily and 70 who received OCALIVA mg once daily.In Trial 1, 216 patients were randomized (1:1:1) to receive either:OCALIVA 10 mg once daily for the entire 12 months of the trial (n=73) OCALIVA titration (5 mg once daily for the initial months, with the option to increase to 10 mg once daily for the last months, in patients who were tolerating OCALIVA, but had ALP 1.67-times ULN or greater, and/or total bilirubin greater than ULN, or less than 15% ALP reduction) (n=70); orplacebo (n=73).During the trial, OCALIVA or placebo was administered in combination with UDCA in 93% of patients and as monotherapy in 7% of patients who were unable to tolerate UDCA. The overall discontinuation rate was 12% in the OCALIVA 10 mg arm, 10% in the OCALIVA titration arm, and 4% in the placebo arm.The recommended starting dosage of OCALIVA is mg orally once daily for months with titration to 10 mg once daily based upon tolerability and response [see Dosage and Administration (2.2)]. Initiation of therapy with OCALIVA 10 mg once daily is not recommended due to an increased risk of pruritus. The most common adverse reactions in Trial occurring in at least 5% of patients in either OCALIVA treatment arm and at an incidence at least 1% higher than the placebo treatment arm are shown in Table 1.Table 1:Most Common Adverse Reactions in Adult Patients with PBC in Trial by Treatment Arm with or without UDCAIn the trial there were 16 patients (7%) who were intolerant and did not receive concomitant UDCA: patients (8%) in the OCALIVA 10 mg arm, patients (7%) in the OCALIVA titration arm, and patients (7%) in the placebo arm.

Hepatic Adverse ReactionsIn Trial 1, the following serious or otherwise clinically significant hepatic adverse reactions were reported at the recommended dosage of OCALIVA: one patient in the OCALIVA 10 mg treatment arm experienced ascites; one patient in the OCALIVA titration treatment arm experienced two episodes of ascites and four episodes of hepatic encephalopathy; one patient in the placebo treatment arm experienced variceal bleeding.. PruritusApproximately 60% of patients had history of pruritus upon enrollment in Trial 1. Treatment-emergent pruritus, including all the terms described in Table 1, generally started within the first month following the initiation of treatment with OCALIVA.The incidence of pruritus was higher in patients who started on OCALIVA 10 mg once daily relative to the OCALIVA titration arm, 70% and 56%, respectively. Discontinuation rates due to pruritus were also higher in patients who started on OCALIVA 10 mg once daily relative to the OCALIVA titration arm, 10% and 1%, respectively.The number of patients with pruritus who required an intervention (e.g., dosage adjustment, treatment interruption, or initiation of bile acid binding resin or antihistamine) was 30 of 51 patients (59%) in the OCALIVA 10 mg arm, 24 of 39 patients (62%) in the OCALIVA titration arm, and 14 of 28 patients (50%) in the placebo arm.

DRUG INTERACTIONS SECTION.


7 DRUG INTERACTIONS. Warfarin: Potential for decreased INR; monitor INR and adjust the dosage of warfarin, as needed, to maintain the target INR range. (7.2)CYP1A2 Substrates with Narrow Therapeutic Index (e.g., theophylline and tizanidine): Potential for increased exposure to CYP1A2 substrates; monitor drug concentrations of CYP1A2 substrates with narrow therapeutic index. (7.3)Inhibitors of Bile Salt Efflux Pump (e.g., cyclosporine): Avoid use. If concomitant use is necessary, monitor serum transaminases and bilirubin. (7.4). Warfarin: Potential for decreased INR; monitor INR and adjust the dosage of warfarin, as needed, to maintain the target INR range. (7.2). CYP1A2 Substrates with Narrow Therapeutic Index (e.g., theophylline and tizanidine): Potential for increased exposure to CYP1A2 substrates; monitor drug concentrations of CYP1A2 substrates with narrow therapeutic index. (7.3). Inhibitors of Bile Salt Efflux Pump (e.g., cyclosporine): Avoid use. If concomitant use is necessary, monitor serum transaminases and bilirubin. (7.4). 7.1Bile Acid Binding Resins. Bile acid binding resins such as cholestyramine, colestipol, or colesevelam adsorb and reduce bile acid absorption and may reduce the absorption, systemic exposure, and efficacy of OCALIVA. If taking bile acid binding resin, take OCALIVA at least hours before or hours after taking the bile acid binding resin, or at as great an interval as possible [see Dosage and Administration (2.5)].. 7.2Warfarin. The International Normalized Ratio (INR) decreased following coadministration of warfarin and OCALIVA [see Clinical Pharmacology (12.3)]. Monitor INR and adjust the dosage of warfarin, as needed, to maintain the target INR range when co-administering OCALIVA and warfarin. 7.3CYP1A2 Substrates with Narrow Therapeutic Index. Obeticholic acid may increase the exposure to concomitant drugs that are CYP1A2 substrates [see Clinical Pharmacology (12.3)]. Therapeutic monitoring of CYP1A2 substrates with narrow therapeutic index (e.g., theophylline and tizanidine) is recommended when co-administered with OCALIVA.. 7.4 Inhibitors of Bile Salt Efflux Pump. Avoid concomitant use of inhibitors of the bile salt efflux pump (BSEP) such as cyclosporine [see Clinical Pharmacology (12.3)]. Concomitant medications that inhibit canalicular membrane bile acid transporters such as the BSEP may exacerbate accumulation of conjugated bile salts including taurine conjugate of obeticholic acid in the liver and result in clinical symptoms. If concomitant use is deemed necessary, monitor serum transaminases and bilirubin.

GERIATRIC USE SECTION.


8.5 Geriatric Use. Of the 201 patients in clinical trials of OCALIVA who received the recommended dosage (5 mg or 10 mg once daily), 41 (20%) were 65 years of age and older, while (4%) were 75 years of age and older. No overall differences in safety or effectiveness were observed between these subjects and subjects less than 65 years of age, but greater sensitivity of some older individuals cannot be ruled out.

HEPATIC IMPAIRMENT SUBSECTION.


8.6 Hepatic Impairment. Hepatic decompensation and failure, sometimes fatal or resulting in liver transplant, have been reported with OCALIVA treatment in PBC patients with cirrhosis, either compensated or decompensated [see Warnings and Precautions (5.1)]. OCALIVA is contraindicated in patients with decompensated cirrhosis (e.g., Child-Pugh Class or C), in those with prior decompensation event, or with compensated cirrhosis who have evidence of portal hypertension (e.g., ascites, gastroesophageal varices, persistent thrombocytopenia) [see Contraindications (4)]. In PBC clinical trials, dose-response relationship was observed for the occurrence of hepatic adverse reactions with OCALIVA [see Warnings and Precautions (5.1)].Plasma exposure to obeticholic acid and its active conjugates, increases significantly in patients with moderate to severe hepatic impairment [see Clinical Pharmacology (12.3)].Routinely monitor patients for progression of PBC with laboratory and clinical assessments. Closely monitor patients with compensated cirrhosis, concomitant hepatic disease, and/or severe intercurrent illness for new evidence of portal hypertension (e.g., ascites, gastroesophageal varices, persistent thrombocytopenia) or increases above the upper limit of normal in total bilirubin, direct bilirubin, or prothrombin time to determine whether drug discontinuation is needed. Permanently discontinue OCALIVA in patients who develop laboratory or clinical evidence of hepatic decompensation, have compensated cirrhosis and develop evidence of portal hypertension, or experience clinically significant hepatic adverse reactions while on treatment. Interrupt treatment during severe intercurrent illness [see Dosage and Administration (2.3), Warnings and Precautions (5.1)].

POSTMARKETING EXPERIENCE SECTION.


6.2 Postmarketing Experience. The following adverse reactions have been identified during post-approval use of OCALIVA. Because these reactions are reported voluntarily from population of uncertain size, it is not always possible to reliably estimate their frequency or establish causal relationship to drug exposure, particularly in PBC patients who have progressive liver disease.. Hepatobiliary Disorders: liver failure, new onset cirrhosis, increased direct and total bilirubin, new or worsening of jaundice [see Warnings and Precautions (5.1)].

LACTATION SECTION.


8.2 Lactation. Risk SummaryThere is no information on the presence of obeticholic acid in human milk, the effects on the breast-fed infant or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mothers clinical need for OCALIVA and any potential adverse effects on the breastfed infant from OCALIVA or from the underlying maternal condition.

MECHANISM OF ACTION SECTION.


12.1 Mechanism of Action. Obeticholic acid is an agonist for FXR, nuclear receptor expressed in the liver and intestine. FXR is key regulator of bile acid, inflammatory, fibrotic, and metabolic pathways. FXR activation decreases the intracellular hepatocyte concentrations of bile acids by suppressing de novo synthesis from cholesterol as well as by increased transport of bile acids out of the hepatocytes. These mechanisms limit the overall size of the circulating bile acid pool while promoting choleresis, thus reducing hepatic exposure to bile acids.

NONCLINICAL TOXICOLOGY SECTION.


13 NONCLINICAL TOXICOLOGY. 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. Carcinogenic potential of obeticholic acid was assessed in carcinogenicity studies of up to years in duration in mice and rats. In mice, there were no drug-related neoplastic findings at doses up to 25 mg/kg/day obeticholic acid, dose that produced systemic exposures approximately 12-times those in humans at the MRHD of 10 mg. In rats, obeticholic acid was administered at doses of 2, 7, and 20 mg/kg/day. At 20 mg/kg/day (approximately 12-times the human exposure at the MRHD), obeticholic acid caused an increase in the incidence of benign granulosa cell tumors in the ovaries and benign granular cell tumors in the cervix and vagina of female rats. There were no drug-related neoplastic findings in male rats. Obeticholic acid was not genotoxic in the Ames test, human peripheral blood lymphocyte chromosomal aberration test, and mouse micronucleus test. The glycine conjugate of obeticholic acid was also not genotoxic in an Ames test and human peripheral blood lymphocyte chromosome aberration test. The taurine conjugate of obeticholic acid was not genotoxic in an Ames test, and was negative in human peripheral blood lymphocyte chromosomal aberration test in the presence of metabolic activation; the findings of the chromosomal aberration assay in the absence of metabolic activation were inconclusive.Obeticholic acid, administered at oral doses of 5, 25, and 50 mg/kg/day to male rats for 28 days before mating and throughout the mating period, and to female rats from 14 days before mating through mating and until gestation day 7, did not alter male or female fertility or early embryonic development at any dose (the 50 mg/kg/day dose is approximately 13-times the human exposure at the MRHD).

OVERDOSAGE SECTION.


10 OVERDOSAGE. In the clinical trials, PBC patients who received OCALIVA 25 mg once daily (2.5-times the highest recommended dosage) or 50 mg once daily (5-times the highest recommended dosage) experienced dose-dependent increase in the incidence of hepatic adverse reactions, including elevations in liver biochemical tests, ascites, jaundice, portal hypertension, and primary biliary cholangitis flares.Serious hepatic adverse reactions have been reported postmarketing in PBC patients with decompensated cirrhosis when OCALIVA was dosed more frequently than the recommended dosage; these adverse reactions were also reported in some patients who received the recommended dosage [see Contraindications (4), Warnings and Precautions (5.1)]. In the case of overdosage, patients should be carefully observed, and supportive care administered, as appropriate.

PREGNANCY SECTION.


8.1 Pregnancy. Risk SummaryThe limited available human data on the use of obeticholic acid during pregnancy are not sufficient to inform drug-associated risk. In animal reproduction studies, no developmental abnormalities or fetal harm was observed when pregnant rats or rabbits were administered obeticholic acid during the period of organogenesis at exposures approximately 13-times and 6-times human exposures, respectively, at the maximum recommended human dose (MRHD) of 10 mg [see Data below].The estimated background risks of major birth defects and miscarriage for the indicated population are unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data. Animal DataIn an embryo-fetal development study in rats, obeticholic acid was administered orally during the period of organogenesis at doses of 5, 25, and 75 mg/kg/day. At 25 mg/kg/day (a dose that produced systemic exposures approximately 13-times those in humans at the MRHD of 10 mg), there was no maternal or developmental toxicity. At 75 mg/kg/day (approximately 40-times the human exposure at the MRHD), decreased fetal body weights and increased numbers of early or late resorptions and nonviable fetuses were observed. In maternal animals, mortality, fetal loss, decreased body weight and food consumption as well as decreased body weight gain were observed at 75 mg/kg/day. Thus, the developmental toxicity observed at this dose may be secondary to maternal toxicity. In rabbits, obeticholic acid was administered orally during the period of organogenesis at doses of 3, 9, and 20 mg/kg/day. Obeticholic acid administered at doses up to 20 mg/kg/day (approximately 6-times the human exposure at the MRHD) was not teratogenic and did not produce any evidence of fetal harm.In pre- and post-natal development study, administration of obeticholic acid in rats during organogenesis through lactation at doses of 5, 25, and 40 mg/kg/day did not produce effects on pregnancy, parturition or postnatal development at any dose (the 40 mg/kg/day dose is approximately 21-times the human exposure at the MRHD).Obeticholic acid exposure margins were calculated using systemic exposure (AUC) values of obeticholic acid plus obeticholic acids active metabolite conjugates (tauro-obeticholic acid and glycol-obeticholic acid) in animals (at the indicated doses) and in humans at the MRHD of 10 mg.

Risk SummaryThere is no information on the presence of obeticholic acid in human milk, the effects on the breast-fed infant or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mothers clinical need for OCALIVA and any potential adverse effects on the breastfed infant from OCALIVA or from the underlying maternal condition.. 8.4 Pediatric Use. The safety and effectiveness of OCALIVA in pediatric patients have not been established.. 8.5 Geriatric Use. Of the 201 patients in clinical trials of OCALIVA who received the recommended dosage (5 mg or 10 mg once daily), 41 (20%) were 65 years of age and older, while (4%) were 75 years of age and older. No overall differences in safety or effectiveness were observed between these subjects and subjects less than 65 years of age, but greater sensitivity of some older individuals cannot be ruled out.. 8.6 Hepatic Impairment. Hepatic decompensation and failure, sometimes fatal or resulting in liver transplant, have been reported with OCALIVA treatment in PBC patients with cirrhosis, either compensated or decompensated [see Warnings and Precautions (5.1)]. OCALIVA is contraindicated in patients with decompensated cirrhosis (e.g., Child-Pugh Class or C), in those with prior decompensation event, or with compensated cirrhosis who have evidence of portal hypertension (e.g., ascites, gastroesophageal varices, persistent thrombocytopenia) [see Contraindications (4)]. In PBC clinical trials, dose-response relationship was observed for the occurrence of hepatic adverse reactions with OCALIVA [see Warnings and Precautions (5.1)].Plasma exposure to obeticholic acid and its active conjugates, increases significantly in patients with moderate to severe hepatic impairment [see Clinical Pharmacology (12.3)].Routinely monitor patients for progression of PBC with laboratory and clinical assessments. Closely monitor patients with compensated cirrhosis, concomitant hepatic disease, and/or severe intercurrent illness for new evidence of portal hypertension (e.g., ascites, gastroesophageal varices, persistent thrombocytopenia) or increases above the upper limit of normal in total bilirubin, direct bilirubin, or prothrombin time to determine whether drug discontinuation is needed. Permanently discontinue OCALIVA in patients who develop laboratory or clinical evidence of hepatic decompensation, have compensated cirrhosis and develop evidence of portal hypertension, or experience clinically significant hepatic adverse reactions while on treatment. Interrupt treatment during severe intercurrent illness [see Dosage and Administration (2.3), Warnings and Precautions (5.1)].

WARNINGS AND PRECAUTIONS SECTION.


5 WARNINGS AND PRECAUTIONS. Hepatic Decompensation and Failure in PBC Patients with Cirrhosis: Routinely monitor patients for progression of PBC, including hepatic adverse reactions, with laboratory and clinical assessments. Closely monitor patients at risk of hepatic decompensation. Permanently discontinue in patients who develop laboratory or clinical evidence of hepatic decompensation; have compensated cirrhosis and develop evidence of portal hypertension; experience clinically significant hepatic adverse reactions; or develop complete biliary obstruction. Interrupt treatment in patients with severe intercurrent illness. (2.3, 4, 5.1)Severe Pruritus: Management strategies include the addition of bile acid binding resins or antihistamines; OCALIVA dosage reduction and/or temporary dosing interruption. (2.4, 5.2)Reduction in HDL-C: Monitor for changes in serum lipid levels during treatment. (5.3). Hepatic Decompensation and Failure in PBC Patients with Cirrhosis: Routinely monitor patients for progression of PBC, including hepatic adverse reactions, with laboratory and clinical assessments. Closely monitor patients at risk of hepatic decompensation. Permanently discontinue in patients who develop laboratory or clinical evidence of hepatic decompensation; have compensated cirrhosis and develop evidence of portal hypertension; experience clinically significant hepatic adverse reactions; or develop complete biliary obstruction. Interrupt treatment in patients with severe intercurrent illness. (2.3, 4, 5.1). Severe Pruritus: Management strategies include the addition of bile acid binding resins or antihistamines; OCALIVA dosage reduction and/or temporary dosing interruption. (2.4, 5.2). Reduction in HDL-C: Monitor for changes in serum lipid levels during treatment. (5.3). 5.1 Hepatic Decompensation and Failure in PBC Patients with Cirrhosis. Hepatic decompensation and failure, sometimes fatal or resulting in liver transplant, have been reported with OCALIVA treatment in PBC patients with cirrhosis, either compensated or decompensated. Among postmarketing cases reporting it, median time to hepatic decompensation (e.g., new onset ascites) was months for patients with compensated cirrhosis; median time to new decompensation event (e.g., hepatic encephalopathy) was 2.5 months for patients with decompensated cirrhosis.Some of these cases occurred in patients with decompensated cirrhosis when they were treated with higher than the recommended dosage for that patient population; however, cases of hepatic decompensation and failure have continued to be reported in patients with decompensated cirrhosis even when they received the recommended dosage.Hepatotoxicity was observed in the OCALIVA clinical trials. dose-response relationship was observed for the occurrence of hepatic adverse reactions including jaundice, worsening ascites, and primary biliary cholangitis flare with dosages of OCALIVA of 10 mg once daily to 50 mg once daily (up to 5-times the highest recommended dosage), as early as one month after starting treatment with OCALIVA in two 3-month, placebo-controlled clinical trials in patients with primarily early stage PBC [see Overdosage (10)].In pooled analysis of three placebo-controlled clinical trials in patients with primarily early stage PBC, the exposure-adjusted incidence rates for all serious and otherwise clinically significant hepatic adverse reactions, and isolated elevations in liver biochemical tests, per 100 patient exposure years (PEY) were: 5.2 in the OCALIVA 10 mg group (highest recommended dosage), 19.8 in the OCALIVA 25 mg group (2.5-times the highest recommended dosage) and 54.5 in the OCALIVA 50 mg group (5-times the highest recommended dosage) compared to 2.4 in the placebo group.. Patient ManagementRoutinely monitor patients for progression of PBC, including hepatic adverse reactions, with laboratory and clinical assessments to determine whether drug discontinuation is needed [see Dosage and Administration (2.3)].Closely monitor patients with compensated cirrhosis, concomitant hepatic disease (e.g., autoimmune hepatitis, alcoholic liver disease), and/or with severe intercurrent illness for new evidence of portal hypertension (e.g., ascites, gastroesophageal varices, persistent thrombocytopenia) or increases above the upper limit of normal in total bilirubin, direct bilirubin, or prothrombin time to determine whether drug discontinuation is needed [see Dosage and Administration (2.3)].Permanently discontinue OCALIVA in patients who:develop laboratory or clinical evidence of hepatic decompensation (e.g., ascites, jaundice, variceal bleeding, hepatic encephalopathy) [see Contraindications (4)].have compensated cirrhosis and develop evidence of portal hypertension (e.g., ascites, gastroesophageal varices, persistent thrombocytopenia) [see Contraindications (4)].experience clinically significant hepatic adverse reactions.develop complete biliary obstruction [see Contraindications (4)].If severe intercurrent illness occurs, interrupt treatment with OCALIVA and monitor the patients liver function. After resolution of the intercurrent illness, consider the potential risks and benefits of restarting OCALIVA treatment.. develop laboratory or clinical evidence of hepatic decompensation (e.g., ascites, jaundice, variceal bleeding, hepatic encephalopathy) [see Contraindications (4)].. have compensated cirrhosis and develop evidence of portal hypertension (e.g., ascites, gastroesophageal varices, persistent thrombocytopenia) [see Contraindications (4)].. experience clinically significant hepatic adverse reactions.. develop complete biliary obstruction [see Contraindications (4)].. 5.2Severe Pruritus. Severe pruritus was reported in 23% of patients in the OCALIVA 10 mg arm, 19% of patients in the OCALIVA titration arm, and 7% of patients in the placebo arm in Trial 1, 12-month double-blind randomized controlled clinical trial of 216 patients [see Adverse Reactions (6.1)]. Severe pruritus was defined as intense or widespread itching, interfering with activities of daily living, or causing severe sleep disturbance, or intolerable discomfort, and typically requiring medical interventions. In the subgroup of patients in the OCALIVA titration arm who increased their dosage from mg once daily to 10 mg once daily after months of treatment (n=33), the incidence of severe pruritus was 0% from Months to and 15% from Months to 12. The median time to onset of severe pruritus was 11, 158, and 75 days for patients in the OCALIVA 10 mg, OCALIVA titration, and placebo arms, respectively. Consider clinical evaluation of patients with new onset or worsening severe pruritus. Management strategies include the addition of bile acid binding resins or antihistamines, OCALIVA dosage reduction, and/or temporary interruption of OCALIVA dosing [see Dosage and Administration (2.4)]. 5.3Reduction in HDL-C. Patients with PBC generally exhibit hyperlipidemia characterized by significant elevation in total cholesterol primarily due to increased levels of high-density lipoprotein-cholesterol (HDL-C). In Trial 1, dose-dependent reductions from baseline in mean HDL-C levels were observed at weeks in OCALIVA-treated patients, 20% and 9% in the 10 mg and titration arms, respectively, compared to 2% in the placebo arm. At Month 12, the reduction from baseline in mean HDL-C level was 19% in the OCALIVA 10 mg arm, 12% in the OCALIVA titration arm, and 2% in the placebo arm. Nine patients in the OCALIVA 10 mg arm, patients in the OCALIVA titration arm, versus patients in the placebo arm had reductions in HDL-C to less than 40 mg/dL.Monitor patients for changes in serum lipid levels during treatment. For patients who do not respond to OCALIVA after year at the highest recommended dosage that can be tolerated (maximum of 10 mg once daily), and who experience reduction in HDL-C, weigh the potential risks against the benefits of continuing treatment.
