Side Effects (Adverse Reactions)

6 ADVERSE REACTIONS The following adverse reactions are discussed in other sections of the labeling: Immune Reconstitution Syndrome [see Warnings and Precautions (5.1) ] Injection Site Reactions [see Warnings and Precautions (5.3) ]. Most common adverse reactions (incidence greater than or equal to 3%, all grades) are nausea and injection site reactions. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Gilead Sciences, Inc. at 1-800-GILEAD-5 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The primary safety assessment of SUNLENCA was based on data from heavily treatment-experienced adult participants with HIV who received SUNLENCA in a Phase 2/3 trial (CAPELLA; N=72) through Week 52 (median duration on study of 71 weeks) [see Clinical Studies (14) ] , as well as supportive data in treatment-naïve adult participants with HIV who received SUNLENCA in a Phase 2 trial (CALIBRATE; N=157) through Week 54 (median duration of exposure of 66 weeks). The most common adverse reactions (all Grades) reported in at least 3% of participants in CAPELLA were nausea and injection site reactions. The proportion of partcipants in CAPELLA who discontinued treatment with SUNLENCA due to adverse events, regardless of severity, was 1% (Grade 1 injection site nodule in 1 participant). Table 3 displays the frequency of adverse reactions (all Grades) greater than or equal to 3% in the SUNLENCA group. Table 3 Adverse Reactions (All Grades) Reported in ≥ 3% Frequencies of adverse reactions are based on all adverse events attributed to trial drug by the investigator, based on all participants (cohorts 1 and 2) in CAPELLA. of Heavily Treatment Experienced Adults with HIV-1 Receiving SUNLENCA in CAPELLA (Week 52 Analysis) Adverse Reactions SUNLENCA + Background Regimen (N=72) Injection Site Reactions 65% Nausea 4% The majority (96%) of all adverse reactions associated with SUNLENCA were mild or moderate in severity. Injection-Associated Adverse Reactions Local Injection Site Reactions (ISRs) : The most frequent adverse reactions were ISRs. Of the 72 participants in CAPELLA, 65% had experienced an ISR attributed to study drug through at least the Week 52 visit. Most participants had mild (Grade 1, 44%) or moderate (Grade 2, 17%) ISRs. Four percent of participants experienced a severe (Grade 3) ISR (erythema, pain, swelling) that resolved within 15 days. The ISRs reported in more than 1% of participants were swelling (36%), pain (31%), erythema (31%), nodule (25%), induration (15%), pruritus (6%), extravasation (3%) and mass (3%). ISRs reported in 1% of participants included discomfort, hematoma, edema, and ulcer. Nodules and indurations at the injection site took longer to resolve than other ISRs. The median time to resolution of all ISRs, excluding nodules and indurations, was 5 days (range: 1 to 183). The median time to resolution of nodules and indurations associated with the first injections of SUNLENCA was 148 (range: 41 to 727) and 70 (range: 3 to 252) days, respectively. After a median follow up of 553 days, 30% of nodules and 13% of indurations (in 10% and 1% of participants, respectively) associated with the first injections of SUNLENCA had not fully resolved. Qualitative descriptions of injection site nodules and indurations were not routinely reported, but, where reported, the majority of injection site nodules and indurations were palpable but not visible. Measurements of injection site nodules and indurations were not routinely performed or standardized, but where measurements were reported, the maximum size for the majority of injection site nodules and indurations was approximately 1 to 4 cm [see Warnings and Precautions (5.3) ] .

Drug Interactions

7 DRUG INTERACTIONS Consult the Full Prescribing Information prior to and during treatment for important drug interactions. ( 4 , 7 , 12.3 ) 7.1 Effect of Other Drugs on SUNLENCA Lenacapavir is a substrate of P-gp, UGT1A1, and CYP3A. Strong or Moderate CYP3A Inducers Drugs that are strong or moderate inducers of CYP3A may significantly decrease plasma concentrations of lenacapavir [see Clinical Pharmacology (12.3) ] , which may result in loss of therapeutic effect of SUNLENCA and development of resistance. Concomitant administration of SUNLENCA with strong CYP3A inducers during SUNLENCA treatment is contraindicated [see Contraindications (4) ] . Concomitant administration of SUNLENCA with moderate CYP3A inducers during SUNLENCA treatment is not recommended. Combined P-gp, UGT1A1, and Strong CYP3A Inhibitors Combined P-gp, UGT1A1, and strong CYP3A inhibitors may significantly increase plasma concentrations of SUNLENCA. Concomitant administration of SUNLENCA with these inhibitors is not recommended. 7.2 Effect of SUNLENCA on Other Drugs Lenacapavir is a moderate inhibitor of CYP3A. Due to the long half-life of lenacapavir following subcutaneous administration, SUNLENCA may increase the exposure of drugs primarily metabolized by CYP3A [see Clinical Pharmacology (12.3) ] initiated within 9 months after the last subcutaneous dose of SUNLENCA, which may increase the potential risk of adverse reactions. See the prescribing information of the sensitive CYP3A substrate for dosing recommendations with moderate inhibitors of CYP3A. 7.3 Established and Other Potentially Significant Drug Interactions Table 5 provides a listing of clinically significant drug interactions with recommended prevention or management strategies, but is not all inclusive. The drug interactions described are based on studies conducted with SUNLENCA or are drug interactions that may occur with SUNLENCA [see Contraindications (4) and Clinical Pharmacology (12.3) ] . Table 5 Drug Interactions with SUNLENCA Concomitant Drug Class: Drug Name Effect on Concentration ↑ = Increase, ↓ = Decrease. Clinical Comment Antiarrhythmics: digoxin ↑ digoxin Use with caution and monitor digoxin therapeutic concentration. Anticoagulants: Direct Oral Anticoagulants (DOACs) rivaroxaban dabigatran edoxaban ↑ DOAC Refer to the DOAC prescribing information for concomitant administration with moderate CYP3A inhibitors and/or P-gp inhibitors. Anticonvulsants: carbamazepine oxcarbazepine phenobarbital phenytoin ↓ lenacapavir Concomitant administration of carbamazepine, oxcarbazepine, phenobarbital, or phenytoin may result in loss of therapeutic effect and development of resistance. Concomitant administration of SUNLENCA with carbamazepine or phenytoin is contraindicated. Concomitant administration of SUNLENCA with oxcarbazepine or phenobarbital is not recommended. Consider use of alternative anticonvulsants. Antiretroviral Agents: atazanavir/cobicistat Drug-drug interaction study was conducted....

Contraindications

4 CONTRAINDICATIONS Concomitant administration of SUNLENCA with strong CYP3A inducers is contraindicated due to decreased lenacapavir plasma concentrations, which may result in the loss of therapeutic effect and development of resistance to SUNLENCA [see Drug Interactions (7.1) ] . Concomitant administration of SUNLENCA is contraindicated with strong CYP3A inducers. ( 4 )

Pregnancy and Breastfeeding

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in individuals exposed to SUNLENCA during pregnancy. Healthcare providers are encouraged to register patients by calling the Antiretroviral Pregnancy Registry (APR) at 1-800-258-4263. Risk Summary There are insufficient human data on the use of SUNLENCA during pregnancy to inform a drug-associated risk of birth defects and miscarriage. In animal reproduction studies, no adverse developmental effects were observed when lenacapavir was administered to rats and rabbits at exposures (AUC) ≥16 times the exposure in humans at the recommended human dose (RHD) of SUNLENCA ( see Data ). The background risk of major birth defects and miscarriage for the indicated population is unknown. The background rate of major birth defects in a U.S. reference population of the Metropolitan Atlanta Congenital Defects Program (MACDP) is 2.7%. The rate of miscarriage is not reported in the APR. The estimated background rate of miscarriage in clinically recognized pregnancies in the U.S. general population is 15 to 20%. Data Animal Data Lenacapavir was administered intravenously to pregnant rabbits (up to 20 mg/kg/day on gestation days (GD) 7 to 19), orally to rats (up to 300 mg/kg/day on GD 6 to 17), and subcutaneously to rats (up to 300 mg/kg on GD 6). No significant toxicological effects on embryo-fetal (rats and rabbits) or pre/postnatal (rats) development were observed at exposures (AUC) approximately 16 times (rats) and 39 times (rabbits) the exposure in humans at the RHD of SUNLENCA.

Overdosage

10 OVERDOSAGE No data are available on overdose of SUNLENCA in patients. If overdose occurs, monitor the patient for evidence of toxicity. Treatment of overdose with SUNLENCA consists of general supportive measures including monitoring of vital signs as well as observation of the clinical status of the patient. As lenacapavir is highly bound to plasma proteins, it is unlikely to be significantly removed by dialysis.
