Infusion-Related Reactions (IRRs)
In the SUSTAIN clinical trial, IRRs (occurring during/within 24 hours of infusion) were observed in 2 (3%) patients treated with ADAKVEO
†The range of VOCs for the ADAKVEO and placebo population was 0 to 24 in each treatment arm.3
ADAKVEO was proven to reduce the frequency of VOCs; however,
the impact on chronic pain was not studied in SUSTAIN.2,3
Per-protocol population is a subset of the ITT patient population who received at least 12 of the 14 planned doses of ADAKVEO (n=40) or placebo (n=41), completed a visit at least 14 days after final dose of study drug, and had no major protocol violations. The per-protocol population was analyzed according to the randomized treatment arm and not powered to show statistical significance.2,3

Infusion-Related Reactions (IRRs)
In the SUSTAIN clinical trial, IRRs (occurring during/within 24 hours of infusion) were observed in 2 (3%) patients treated with ADAKVEO 5 mg/kg. Postmarketing cases of IRRs, including severe pain events requiring hospitalizations, have been reported. The majority of these IRRs occurred during the first and second infusions. The management of pain events included acetaminophen, nonsteroidal anti-inflammatory drugs (NSAIDs), opioids, antihistamines, intravenous fluids, and/or oxygen therapy. Some patients have also experienced subsequent complications such as acute chest syndrome and fat embolism, particularly those treated with steroids.
Monitor patients for signs and symptoms of IRRs, which may include pain in various locations, headache, fever, chills, nausea, vomiting, diarrhea, fatigue, dizziness, pruritus, urticaria, sweating, or shortness of breath or wheezing.
For severe IRRs, discontinue infusion, institute appropriate medical care, and consider permanent discontinuation of ADAKVEO. For mild or moderate IRRs, temporarily interrupt or slow the rate of infusion and initiate symptomatic treatment. For subsequent infusions, consider premedication and/or reduce the infusion rate.
Exercise caution with corticosteroids in patients with sickle cell disease unless clinically indicated (eg, treatment of anaphylaxis).
Laboratory Test Interference (Platelet Counts)
Interference with automated platelet counts (platelet clumping) has been observed following administration of ADAKVEO, in particular, when blood samples were collected in tubes containing EDTA.
Run blood samples within 4 hours of blood collection or collect blood samples in tubes containing citrate. When needed, estimate platelet count via peripheral blood smear.
Pregnancy
Based on animal data, ADAKVEO has the potential to cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. ADAKVEO should only be used during pregnancy if the expected benefit to the patient justifies the potential risk to the fetus.
Most Common Adverse Reactions
The most frequently reported adverse reactions (≥10%) in patients treated with ADAKVEO were nausea (18%), arthralgia (18%), back pain (15%), abdominal pain (12%), and pyrexia (11%).
Other Clinically Important Adverse Reactions
Clinically relevant adverse reactions (all grades) that were reported in <10% of patients treated with ADAKVEO included: oropharyngeal pain, diarrhea, 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.

The key secondary end point in the SUSTAIN study was defined as the annual rate of days a patient was hospitalized, including those related to VOCs. The range of days hospitalized for the ADAKVEO and placebo population was 0 to 131 days and 0 to 307 days, respectively.3
Results are based on 2 post hoc analyses of the key secondary end point and are observational in nature; as such, they were not powered to show statistical significance.
What could fewer days in the hospital mean for your patients?
HR, hazard ratio.
Patients who did not experience a VOC that led to a health care visit during treatment: A patient was considered to not have experienced a VOC if the annualized VOC rate was zero, whether or not the patient completed the 12-month treatment period.2,3
The efficacy of ADAKVEO® (crizanlizumab-tmca) was evaluated based on the annual rate of VOCs in patients (16 to 63 years of age) with SCD in a pivotal, phase 2, 52-week, randomized, multicenter, placebo-controlled, double-blind study.‡ The study included 198 patients evaluated at 60 study centers, the majority of which were located in the United States (51 centers with 151 study patients)1-3§
Prespecified, noncomparative subgroup analysis evaluated the annual rate of VOCs with or without HU
SUSTAIN studied the efficacy of ADAKVEO in all major SCD patient types over the course of 52 weeks, regardless of VOC BASELINE FREQUENCY1
ADAKVEO® (crizanlizumab-tmca) is indicated to reduce the frequency of vaso-occlusive crises (VOCs) in adults and pediatric patients, aged 16 years and older, with sickle cell disease.
