ADVERSE REACTIONS SECTION.

6 ADVERSE REACTIONS. 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.The safety data reflect the exposure of 421 participants with ATTR-CM to ATTRUBY 712 mg (administered as two 356 mg tablets) administered orally twice daily in randomized, double-blind, placebo-controlled trial of 30 months fixed treatment duration. The median duration of exposure to ATTRUBY in the safety population was 29 months. There was higher frequency of gastrointestinal (GI) adverse reactions such as diarrhea 11.6% versus 7.6% and upper abdominal pain 5.5% versus 1.4% in the ATTRUBY versus placebo group, respectively. The majority of these GI adverse reactions were categorized as mild and resolved without drug discontinuation.A similar proportion of ATTRUBY-treated and placebo-treated participants discontinued study drug because of an adverse event (9.3% and 8.5%, respectively).. Laboratory Tests. Increase in Serum Creatinine and Decrease in eGFRInitiation of ATTRUBY causes an increase in serum creatinine and decrease in eGFR which generally occurs within weeks of starting therapy and stabilizes. In trial of adults with ATTR-CM, mean increase in serum creatinine of 0.2 and 0.0 mg/dL and mean decrease in eGFR of 8.2 and 0.7 mL/min/1.73 m2 was observed in the ATTRUBY and placebo groups, respectively, at Day 28. The changes in serum creatinine and eGFR were reversible after treatment discontinuation.

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. CarcinogenesisThere was no evidence of increased incidence of neoplasia in 2-year carcinogenicity study in male rats dosed up to 50 mg/kg and in female rats dosed up to 350 mg/kg, which provided exposures approximately equivalent to and 11 times the AUC at the maximum recommended human dose (MRHD), respectively. There was no evidence of an increased incidence of neoplasia in transgenic (Tg.rasH2) mice following repeated daily administration for 26 weeks at daily doses up to 300 mg/kg.. MutagenesisThere was no evidence of mutagenicity or clastogenicity for acoramidis in an Ames assay or in vivo rat micronucleus and alkaline comet assay.. Impairment of FertilityIn male and female fertility study, rats were orally administered acoramidis at 0, 50, 350, and 1,000 mg/kg/day. Male rats were given acoramidis prior to and during cohabitation for total of up to 52 days. Female rats were given acoramidis prior to and during cohabitation until implantation of the embryo (Gestational Day 7) for total of up to 34 days. There were no effects on fertility, reproductive performance, or mating behavior in male or female rats at doses up to 1,000 mg/kg/day, approximately 38-times the AUC at the MRHD.

CLINICAL PHARMACOLOGY SECTION.

12 CLINICAL PHARMACOLOGY. 12.1 Mechanism of Action. Acoramidis is selective stabilizer of transthyretin (TTR). Acoramidis binds TTR at thyroxine binding sites and slows dissociation of the TTR tetramer into its constituent monomers, the rate-limiting step in amyloidogenesis.. 12.2 Pharmacodynamics. TTR StabilizationChanges in serum TTR level or in vitro TTR stabilization assays were utilized as pharmacodynamic markers of TTR stabilization. Increases in mean serum TTR levels were observed by Day 28 in ATTR-CM patients treated with ATTRUBY. Near-complete in vitro TTR stabilization was observed as early as Day 28 and through completion of 30-month study of patients with ATTR-CM (wild-type and variant) treated with the recommended dosage [see Clinical Studies (14)].. Free thyroxineATTRUBY may decrease serum concentrations of free thyroxine without an accompanying change in thyroid stimulating hormone (TSH). reduction in free thyroxine values has been observed with transthyretin stabilizers probably due to reduced thyroxine binding to or displacement from transthyretin (TTR).. NT-proBNP and Troponin IIn clinical study of ATTRUBY in patients with ATTR-CM, at Month 30, the increase in N-terminal prohormone of brain natriuretic peptide [NT-proBNP] and troponin was lower with ATTRUBY versus placebo. The increase in NT-proBNP at Month 30 for ATTRUBY was about half that of placebo [see Clinical Studies (14)].. Cardiac ElectrophysiologyAt approximately 1.2 times the steady state peak plasma concentrations (Cmax) at the recommended dose, ATTRUBY does not prolong the QTc interval to any clinically relevant extent.. 12.3 Pharmacokinetics. The systemic exposures (Cmax and AUC) increase in less than dose proportional manner following single and multiple doses of acoramidis. Over the dose range from 89 mg twice daily to 712 mg twice daily, AUC increases only 130%. Acoramidis steady state is achieved by days with approximately 1.3-fold accumulation at the approved recommended dosage. At steady state, dose of 712 mg twice daily results in mean (SD) Cmax of 13700 (6090) ng/mL and AUC0-12h of 47200 (10300) ng.h/mL.. AbsorptionThe time to Cmax of acoramidis (Tmax) is approximately hour following oral administration.. Effect of FoodNo clinically significant differences in acoramidis pharmacokinetics were observed following administration of high-fat meal (800-1000 total calories, >= 50% fat).. DistributionThe apparent steady-state volume of distribution for acoramidis is 654 liters. Acoramidis is 96% bound to human plasma proteins in vitro. Acoramidis primarily binds to TTR.. EliminationThe effective half-life of acoramidis is approximately hours with steady state apparent clearance of 16 L/hr.. MetabolismAcoramidis is primarily metabolized by glucuronidation via UGT1A9, UGT1A1 and UGT2B7. Acoramidis--D-glucuronide (Acoramidis-AG) is the predominant metabolite of acoramidis (8% of total circulating drug related moieties).Acoramidis-AG is approximately 1/3 as pharmacologically active compared with acoramidis, has low potential for covalent binding, and does not contribute to pharmacological activity.. ExcretionAfter single oral dose of radiolabeled acoramidis 712 mg to healthy adult subjects, approximately 32% of the dose radioactivity was recovered in feces (15% unchanged), and approximately 68% was recovered in urine (<10% unchanged).. Specific PopulationsNo clinically significant differences in the pharmacokinetics of acoramidis were observed based on age, race/ethnicity (including Japanese and non-Japanese), sex, or renal impairment. The effect of hepatic impairment (Child Pugh A, B, or C) on acoramidis pharmacokinetics is unknown.. Drug Interaction Studies. Clinical StudiesFollowing the administration of acoramidis (712 mg, BID) in clinical study in healthy adult volunteers, there was not clinically significant increase in exposure to the organic anion transporter-1 (OAT1) substrate (adefovir) and to OAT3 substrate (oseltamivir carboxylate).Concomitant diuretic use in patients does not affect steady-state plasma acoramidis concentrations.. In Vitro Studies. Cytochrome P450 Enzymes:Acoramidis is time-dependent inhibitor of CYP2C9, but does not inhibit CYP1A2, CYP2B6, CYP2C8, CYP2C19, CYP2D6, or CYP3A4/5. Acoramidis does not induce CYP1A2, CYP2B6, or CYP3A4.. UDP-Glucuronosyl Transferase (UGT):Acoramidis is substrate of multiple UGT enzymes including UGT1A9, UGT1A1, and UGT2B7.. Transporter Systems:Acoramidis is substrate for OAT1 and breast cancer resistance protein (BCRP).Acoramidis inhibits OAT1 and OAT3, but does not inhibit MATE1, OCT1, OCT2, OATP1B1, OATP1B3, MATE2-K, BCRP, P-gp, or BSEP.

CLINICAL STUDIES SECTION.

14 CLINICAL STUDIES. The efficacy of ATTRUBY was demonstrated in multicenter, international, randomized, double-blind, placebo-controlled study in 611 adult patients with wild-type or variant (hereditary or de novo) ATTR-CM (NCT03860935).Participants were randomized (2:1) to receive ATTRUBY 712 mg (n=409) or placebo (n=202) twice daily for 30 months. Treatment assignment was stratified by type of ATTR-CM [variant (ATTRv-CM) or wild-type (ATTRwt-CM)], NT-proBNP level, and estimated glomerular filtration rate (eGFR). The mean age of study participants was 77 years, 90.8% were male, 87.9% were White, 4.7% Black or African American, 2.1% Asian, 5.3% race other, 19% had history of permanent pacemaker and 58% had history of atrial fibrillation. No significant imbalance in baseline characteristics was observed between the two treatment groups.Participants were permitted to initiate open-label tafamidis after 12 months in the study. total of 107 participants received tafamidis: 61 (14.9%) in the ATTRUBY arm and 46 (22.8%) in the placebo arm. The median time to initiation of tafamidis for these 107 participants was 17 months.The primary composite endpoint included all-cause mortality (ACM) and cumulative frequency of cardiovascular-related hospitalizations (CVH) over 30 months, analyzed hierarchically using the stratified Finkelstein-Schoenfeld (F-S) test. The F-S test demonstrated statistically significant reduction (p=0.018) in ACM and cumulative frequency of CVH in the ATTRUBY arm versus the placebo arm. All-cause mortality was reported in 19% and 26% of participants in the ATTRUBY and placebo groups, respectively. The majority (79%) of the deaths were cardiovascular. CVH was reported in 27% and 43% of participants in the ATTRUBY and placebo groups, respectively. The mean number of CVH events was 0.3 vs 0.6 per year. The majority (59%) of CVH were heart failure hospitalizations reported in 13% and 26% of the participants in the ATTRUBY and placebo groups, respectively.The treatment effect of ATTRUBY on functional capacity and health status was assessed by the 6MWD and the Kansas City Cardiomyopathy Questionnaire-Overall Summary score (KCCQ-OS) respectively. At month 30, the LS mean difference (95% CI) in change from baseline in 6MWD was 40 [21, 58] meters (p 0.0001) and change from baseline in KCCQ-OS was 10 [6, 14] points (p 0.0001) (Figure and Figure 2).Figure - 6MWD Change from BaselineFigure - KCCQ-OS Score Change from BaselineAbbreviations: 6MWD Six-Minute Walk Distance; KCCQ-OS Kansas City Cardiomyopathy Questionnaire Overall Summary Score; SE standard error; LS least squares.The changes from baseline in 6MWT and KCCQ-OS were analyzed using the mixed model for repeated measures (MMRM) with treatment group, visit, genotype (ATTRv-CM vs ATTRwt-CM), NT-proBNP level (<= 3000 vs 3000 pg/mL), eGFR level (>= 45 vs 45 mL/min/1.73 m2) and treatment group-by-visit interaction as factors, and baseline value as covariate.A Cox regression analysis indicated 35.5% decrease in the risk of the composite of ACM or first CV hospitalization (hazard ratio: 0.645 [95% CI: 0.500, 0.832]).

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.The safety data reflect the exposure of 421 participants with ATTR-CM to ATTRUBY 712 mg (administered as two 356 mg tablets) administered orally twice daily in randomized, double-blind, placebo-controlled trial of 30 months fixed treatment duration. The median duration of exposure to ATTRUBY in the safety population was 29 months. There was higher frequency of gastrointestinal (GI) adverse reactions such as diarrhea 11.6% versus 7.6% and upper abdominal pain 5.5% versus 1.4% in the ATTRUBY versus placebo group, respectively. The majority of these GI adverse reactions were categorized as mild and resolved without drug discontinuation.A similar proportion of ATTRUBY-treated and placebo-treated participants discontinued study drug because of an adverse event (9.3% and 8.5%, respectively).. Laboratory Tests. Increase in Serum Creatinine and Decrease in eGFRInitiation of ATTRUBY causes an increase in serum creatinine and decrease in eGFR which generally occurs within weeks of starting therapy and stabilizes. In trial of adults with ATTR-CM, mean increase in serum creatinine of 0.2 and 0.0 mg/dL and mean decrease in eGFR of 8.2 and 0.7 mL/min/1.73 m2 was observed in the ATTRUBY and placebo groups, respectively, at Day 28. The changes in serum creatinine and eGFR were reversible after treatment discontinuation.

PHARMACODYNAMICS SECTION.

12.2 Pharmacodynamics. TTR StabilizationChanges in serum TTR level or in vitro TTR stabilization assays were utilized as pharmacodynamic markers of TTR stabilization. Increases in mean serum TTR levels were observed by Day 28 in ATTR-CM patients treated with ATTRUBY. Near-complete in vitro TTR stabilization was observed as early as Day 28 and through completion of 30-month study of patients with ATTR-CM (wild-type and variant) treated with the recommended dosage [see Clinical Studies (14)].. Free thyroxineATTRUBY may decrease serum concentrations of free thyroxine without an accompanying change in thyroid stimulating hormone (TSH). reduction in free thyroxine values has been observed with transthyretin stabilizers probably due to reduced thyroxine binding to or displacement from transthyretin (TTR).. NT-proBNP and Troponin IIn clinical study of ATTRUBY in patients with ATTR-CM, at Month 30, the increase in N-terminal prohormone of brain natriuretic peptide [NT-proBNP] and troponin was lower with ATTRUBY versus placebo. The increase in NT-proBNP at Month 30 for ATTRUBY was about half that of placebo [see Clinical Studies (14)]..

PREGNANCY SECTION.

8.1 Pregnancy. Risk SummaryAvailable data with acoramidis use in pregnant women are insufficient to establish drug associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes. In animal reproductive studies in rats and rabbits, no embryofetal abnormalities were observed at exposures up to 34 times and 13 times the clinical exposure at the maximum recommended human dose, respectively (see Data ).The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have background risk of birth defects, loss, or other adverse outcomes. 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.Report pregnancies to the BridgeBio reporting line at 1-844-550-2246.. Data. Animal DataIn pregnant rats, oral administration of acoramidis (0, 50, 350, and 1,000 mg/kg/day) throughout organogenesis did not result in any adverse effects on embryofetal development at up to 1,000 mg/kg/day, approximately 34 times the clinical exposure at the maximum recommended human dose (MRHD) based on AUC.In pregnant rabbits, oral administration of acoramidis (0, 25, 75, and 200 mg/kg/day) throughout organogenesis resulted in increased pre-implantation loss at 200 mg/kg/day, dose that caused maternal toxicity (26% reduced body weight gain). No embryofetal abnormalities were observed at 200 mg/kg/day, approximately 13 times the clinical exposure at the MRHD based on AUC.In pre- and postnatal developmental toxicity study, pregnant rats received oral administration of acoramidis at doses of 0, 50, 350, or 1,000 mg/kg/day throughout pregnancy and lactation (Gestation Day to Lactation Day 20). Maternal death, body weight reduction, and decreased number of females with live born pups (due to increase in resorbed litters) were observed at 1,000 mg/kg/day, approximately 43 times the clinical exposure at the MRHD based on AUC. Decreased body weight gain from the neonatal period to weaning and learning deficits were observed in the offspring of dams given 1,000 mg/kg/day. No adverse effects on pre- and postnatal development were observed at 350 mg/kg/day, approximately 18 times the clinical exposure at the MRHD based on AUC.

8 USE IN SPECIFIC POPULATIONS. 8.1 Pregnancy. Risk SummaryAvailable data with acoramidis use in pregnant women are insufficient to establish drug associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes. In animal reproductive studies in rats and rabbits, no embryofetal abnormalities were observed at exposures up to 34 times and 13 times the clinical exposure at the maximum recommended human dose, respectively (see Data ).The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have background risk of birth defects, loss, or other adverse outcomes. 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.Report pregnancies to the BridgeBio reporting line at 1-844-550-2246.. Data. Animal DataIn pregnant rats, oral administration of acoramidis (0, 50, 350, and 1,000 mg/kg/day) throughout organogenesis did not result in any adverse effects on embryofetal development at up to 1,000 mg/kg/day, approximately 34 times the clinical exposure at the maximum recommended human dose (MRHD) based on AUC.In pregnant rabbits, oral administration of acoramidis (0, 25, 75, and 200 mg/kg/day) throughout organogenesis resulted in increased pre-implantation loss at 200 mg/kg/day, dose that caused maternal toxicity (26% reduced body weight gain). No embryofetal abnormalities were observed at 200 mg/kg/day, approximately 13 times the clinical exposure at the MRHD based on AUC.In pre- and postnatal developmental toxicity study, pregnant rats received oral administration of acoramidis at doses of 0, 50, 350, or 1,000 mg/kg/day throughout pregnancy and lactation (Gestation Day to Lactation Day 20). Maternal death, body weight reduction, and decreased number of females with live born pups (due to increase in resorbed litters) were observed at 1,000 mg/kg/day, approximately 43 times the clinical exposure at the MRHD based on AUC. Decreased body weight gain from the neonatal period to weaning and learning deficits were observed in the offspring of dams given 1,000 mg/kg/day. No adverse effects on pre- and postnatal development were observed at 350 mg/kg/day, approximately 18 times the clinical exposure at the MRHD based on AUC.. 8.2 Lactation. Risk SummaryThere are no available data on the presence of acoramidis in either human or animal milk or the effects of the drug on the breastfed infant or maternal milk production. The developmental and health benefits of breastfeeding should be considered along with the mothers clinical need for ATTRUBY and any potential adverse effects on the breastfed child from ATTRUBY or from the underlying maternal condition.. 8.4 Pediatric Use. The safety and effectiveness of ATTRUBY have not been established in pediatric patients.. 8.5 Geriatric Use. No dosage adjustment is required for elderly patients (>=65 years) [see Clinical Pharmacology (12.3)]. Of the total number of participants randomized in the clinical study (n=632), 97% were 65 years and over, with median age of 78 years.
