The following clinically significant adverse reactions are described elsewhere in the labeling: Infusion-related reactions [see Warnings and Precautions (5.1)] The most common adverse reactions (incidence ≥ 10%) were headache, arthralgia, nausea, back pain, fatigue, abdominal pain, pyrexia, diarrhea, vomiting, and oropharyngeal pain.

6.1Clinical 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. Sickle Cell Disease SUSTAIN Trial The safety of ADAKVEO was evaluated in the SUSTAIN trial [see Clinical Studies (14.1)] . Eligible patients were diagnosed with sickle cell disease (any genotype, including HbSS, HbSC, HbS beta 0 -thalassemia, HbS beta + -thalassemia, and others).
Patients received ADAKVEO 5 mg/kg (N = 66) or 2.5 mg/kg (N = 64) or placebo (N = 62) administered by intravenous infusion on Week 0, Week 2, and every 4 weeks thereafter. The safety evaluation below is limited to the patients who received the recommended dose of 5 mg/kg. Among the 66 patients that received the recommended dose (5 mg/kg), 83% were exposed for 6 months or longer and 61% were exposed for approximately one year; forty-two (64%) patients were treated with ADAKVEO in combination with hydroxyurea.
Serious adverse reactions were reported in 2 patients (3%) treated with ADAKVEO 5 mg/kg; both reactions were pyrexia. Two deaths (3%) occurred in the ADAKVEO 5 mg/kg treatment group. None of the deaths were considered to be related to ADAKVEO. The most common adverse reactions (≥ 10%) were arthralgia, nausea, back pain, abdominal pain, pyrexia, and diarrhea. Table 1 summarizes the adverse reactions in the SUSTAIN trial.
Table 1: Adverse Reactions (≥ 10%) in Patients Receiving ADAKVEO With a Difference Between Arms of > 3% Compared to Placebo in SUSTAIN a Abdominal pain: abdominal pain, upper abdominal pain, lower abdominal pain, and abdominal tenderness. ADAKVEO 5 mg/kg N = 66 % Placebo N = 62 % Adverse Reactions All Grades % Grade ≥ 3 % All Grades % Grade ≥ 3 % Arthralgia 18 2 8 2 Nausea 18 0 11 2 Back pain 15 0 11 0 Abdominal pain a 12 0 5 0 Pyrexia 11 12 7 0 Diarrhea 11 0 3 2 Clinically relevant adverse reactions (all Grades) that were reported in less than 10% of patients treated with ADAKVEO included: oropharyngeal pain, vomiting, pruritus (pruritus and vulvovaginal pruritus), musculoskeletal chest pain, myalgia, infusion-site reaction (infusion-site extravasation, infusion-site pain, and infusion-site swelling), and infusion-related reaction.
STAND Trial The safety of ADAKVEO was also evaluated in the STAND trial [see Clinical Studies (14.1)] . Eligible patients were diagnosed with sickle cell disease (any genotype, including HbSS, HbSC, HbS beta 0 -thalassemia, HbS beta + -thalassemia, and others). Patients received ADAKVEO 5 mg/kg (N = 84) or 7.5 mg/kg (N = 83) or placebo (N = 85) administered by intravenous infusion on Week 0, Week 2, and every 4 weeks thereafter.
The safety evaluation below is limited to the patients who received the recommended dose of 5 mg/kg. Among the 84 patients that received the recommended dose (5 mg/kg), 93% were exposed for approximately 6 months or longer and 88% were exposed for approximately one year; sixty-two (74%) patients were treated with ADAKVEO in combination with hydroxyurea. Serious adverse reactions were reported in 2 patients (2%) treated with ADAKVEO 5 mg/kg and this reaction was pain.
The most common adverse reactions (≥ 10%) were headache, nausea, fatigue, vomiting, and oropharyngeal pain. Table 2: Adverse Reactions (≥ 10%) in Patients Receiving ADAKVEO With a Difference Between Arms of > 3% Compared to Placebo in STAND a Fatigue includes asthenia and malaise. ADAKVEO 5 mg/kg N = 84 % Placebo N = 85 % Adverse Reactions All Grades % Grade ≥ 3 % All Grades % Grade ≥ 3 % Headache 25 1 19 0 Nausea 17 0 9 0 Fatigue a 13 0 8 0 Vomiting 10 0 5 0 Oropharyngeal pain 10 0 4 0 Clinically relevant adverse reactions (all Grades) that were reported in less than 10% of patients treated with ADAKVEO or events having a difference of less than 3% between ADAKVEO treatment arms and placebo included: diarrhea, pruritus, dizziness, infusion-related reaction, infusion-site reaction.
