Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect rates observed in practice.

The safety assessment of CABENUVA is based on the analysis of pooled 48-week data from 1,182 virologically suppressed participants with HIV-1 infection in 2 international, multicenter, open-label pivotal trials, FLAIR and ATLAS, and 1,045 virologically suppressed participants from the ATLAS-2M trial

Adverse reactions were reported following exposure to CABENUVA extended-release injectable suspensions (median time exposure at the time of analysis: 54 weeks in FLAIR and ATLAS, and 64 weeks in ATLAS-2M) and data from VOCABRIA (cabotegravir) tablets and EDURANT (rilpivirine) tablets administered in combination as oral lead-in therapy (median time exposure: 5.3 weeks in FLAIR and ATLAS, and 5.6 weeks in ATLAS-2M). Adverse reactions included those attributable to both the oral and injectable formulations of cabotegravir and rilpivirine administered as a combination regimen. Refer to the prescribing information for EDURANT (rilpivirine) for other adverse reactions associated with oral rilpivirine.

The most common adverse reactions regardless of severity reported in ≥2% of adult participants from FLAIR and ATLAS at Week 48 are presented in

In the extension phase of the FLAIR study at Week 124, the overall safety profile was consistent with that observed at Week 48 and when injection therapy with CABENUVA was initiated directly without the oral lead-in phase.

Overall, 4% of participants in the group receiving CABENUVA and 2% of participants in the control group in FLAIR and ATLAS discontinued due to adverse events. Non-injection-site-related adverse events leading to discontinuation and occurring in more than 1 participant were headache, diarrhea, hepatitis A, and acute hepatitis B (all with an incidence <1%). In ATLAS-2M, 2% of participants in both treatment groups discontinued due to adverse events. Non-injection-site–related adverse events leading to discontinuation and occurring in more than 1 participant in ATLAS-2M were fatigue, pyrexia, headache, presyncope, acute hepatitis B, hyperhidrosis, and abnormal dreams that occurred with an incidence of ≤1% in either treatment group.

In ATLAS-2M, the type and frequency of adverse reactions reported in participants receiving CABENUVA once monthly or CABENUVA once every 2 months for 48 weeks were similar. Differences between treatment arms were reported for the types of injection-associated adverse reactions (see Injection-Associated Adverse Reactions for additional information).

In the pooled analysis of FLAIR and ATLAS, 83% of participants reported any injection site reaction with the monthly dosing regimen, with 1% of participants who discontinued treatment with CABENUVA because of ISRs. After 14,682 injections, 3,663 ISRs were reported. The severity of ISRs was generally mild (Grade 1: 75% of participants) or moderate (Grade 2: 36% of participants). Four percent (4%) of participants experienced severe (Grade 3) ISRs, and no participant experienced Grade 4 ISRs. The median duration of overall ISR events was 3 days. The most commonly reported ISR in FLAIR and ATLAS was pain/discomfort, with 79% reported in the group receiving CABENUVA.

In ATLAS-2M, 75% of participants reported any injection site reaction in both the monthly and every‑2‑month dosing regimens, with <1% of participants who discontinued treatment with CABENUVA because of ISRs. When dosing monthly, after 15,711 injections, 3,152 ISRs were reported. When dosing every 2 months, after 8,470 injections, 2,507 ISRs were reported. The severity of ISRs was generally mild (Grade 1: 70% and 71% of participants) or moderate (Grade 2: 28% and 27% of participants) in monthly and every‑2‑month dosing regimens, respectively. Four percent (4%) of participants in the monthly group and 3% of participants in the every‑2‑month group experienced severe (Grade 3) ISRs, and no participant experienced Grade 4 ISRs. The median duration of overall ISR events was 3 days for both dosing regimens. The most commonly reported ISR in ATLAS‑2M was pain/discomfort, with 71% and 73% reported in the monthly and every‑2‑month dosing regimens, respectively. The severity and duration of ISRs, including pain/discomfort, were similar for both dosing regimens and in participants without prior exposure to CABENUVA.

The most commonly reported ISR (Grades 1 to 3) in at least 1% of adult participants in the pooled analyses from FLAIR and ATLAS, and from ATLAS‑2M, are presented in

In ATLAS and FLAIR, reports of musculoskeletal pain (3%) and less frequently, sciatica, were also more common in participants receiving cabotegravir plus rilpivirine compared with the current antiretroviral regimen and some events had a temporal association with injection.

Vasovagal or pre-syncopal reactions were reported in <1% of participants after injection with rilpivirine or cabotegravir.

Based on data from the Week 16 (cohort 1) and Week 24 (cohort 2) analyses of the MOCHA study, the safety profile in adolescents (aged 12 to younger than 18 years and weighing ≥35 kg) was consistent with the safety profile established with cabotegravir plus rilpivirine in adults

In cohort 1, 55 virologically suppressed adolescents with HIV-1 received background antiretroviral therapy in addition to either oral cabotegravir (n = 30) followed by injectable cabotegravir (n = 29), or oral rilpivirine (n = 25) followed by injectable rilpivirine (n = 23). Adverse reactions were reported in 38% of adolescents receiving either cabotegravir or rilpivirine. Thirty-three percent of participants reported at least 1 ISR. All ISRs were Grade 1 or Grade 2. Two participants had Grade 3 adverse reactions of hypersensitivity (n = 1, oral rilpivirine) and insomnia (n = 1, injectable cabotegravir). The Grade 3 adverse reaction of drug hypersensitivity led to discontinuation of rilpivirine during oral lead-in. The adverse reactions reported by more than one participant (regardless of severity) were injection site pain (n = 18), headache (n = 2), hypersensitivity (n = 2), insomnia (n = 2), and nausea (n = 2).

In cohort 2, 144 virologically suppressed adolescents with HIV-1 received oral cabotegravir plus oral rilpivirine followed by injectable cabotegravir plus injectable rilpivirine. Adverse reactions were reported in 35% of adolescents receiving cabotegravir plus rilpivirine. Thirty-four percent of participants reported at least 1 ISR. The majority of these participants experienced Grade 1 or Grade 2 ISRs. Two participants had Grade 3 ISRs consisting of injection site abscess (n = 2) and injection site pain in one of these two participants (symptoms resolved in both participants). All non-ISR adverse reactions were ≤ Grade 2. Non-injection-site associated adverse reactions reported by more than one participant (regardless of severity) were headache (n = 3), nausea (n = 2), rash (n = 2) and rash pruritic (n = 2).

The following adverse reactions have been identified during postmarketing experience in patients receiving cabotegravir- or oral-rilpivirine-containing regimens. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Hypersensitivity reactions (including angioedema and urticaria)

Nephrotic syndrome.

Severe skin and hypersensitivity reactions, including DRESS, Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN)
