Side Effects & Drug Interactions

SIDE EFFECTS

The following clinically significant adverse reactions are described elsewhere in the labeling:

Infusion-related reactions [see WARNINGS AND PRECAUTIONS]

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.

Sickle Cell Disease

The safety of ADAKVEO was evaluated in the SUSTAIN trial [see Clinical Studies]. Eligible patients were diagnosed with sickle cell disease (any genotype, including HbSS, HbSC, HbS beta⁰-thalassemia, HbSbeta⁺-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 nausea, arthralgia, back pain, abdominal pain, and pyrexia. These adverse reactions, along with myalgia, musculoskeletal chest pain, and diarrhea may be signs and symptoms of an infusion-related reaction when observed during/within 24 hours of an infusion [see WARNINGS AND PRECAUTIONS].

Table 2 summarizes the adverse reactions in the SUSTAIN trial.

Table 2: Adverse Reactions (≥ 10%) in Patients Receiving ADAKVEO With a Difference Between Arms of > 3% Compared to Placebo in SUSTAIN

Adverse Reactions	ADAKVEO 5 mg/kg N = 66 n (%)		Placebo N = 62 n (%)
Adverse Reactions	All Grades (%)	Grade ≥ 3 (%)	All Grades (%)	Grade ≥ 3 (%)
Gastrointestinal Disorders
Nausea	12 (18)	0	7 (11)	1 (2)
Abdominal pain^a	8 (12)	0	3 (5)	0
Musculoskeletal and Connective Tissue Disorders
Arthralgia	12 (18)	1 (2)	5 (8)	1 (2)
Back pain	10 (15)	0	7 (11)	0
General Disorders and Administration Site Conditions
Pyrexia	7 (11)	1 (2)	4 (7)	0
^aAbdominal pain: abdominal pain, upper abdominal pain, lower abdominal pain, and abdominal tenderness.

Clinically relevant adverse reactions (all Grades) that were reported in less than 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.

Immunogenicity

As with all therapeutic proteins, there is potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors, including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies in the studies described below with the incidence of antibodies in other studies or to other crizanlizumab products may be misleading.

The immunogenicity of ADAKVEO was evaluated using a validated bridging immunoassay for the detection of binding anti-crizanlizumab-tmca antibodies. In a single arm, open label multiple dose study, 0 of the 45 patients with sickle cell disease treated with ADAKVEO 5 mg/kg tested positive for treatment-induced anti-crizanlizumab-tmca antibodies. In a single-dose study of healthy subjects, 1 of the 61 (1.6%) evaluable subjects tested positive for a treatment-induced anticrizanlizumab-tmca antibodies.

Postmarketing Experience

The following adverse reactions have been identified during postapproval use of ADAKVEO. 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.

General Disorders and Administration-site Conditions: Pain (in various locations) occurring during/within 24 hours of the infusion (e.g., potential infusion-related reaction) [see WARNINGS AND PRECAUTIONS].

DRUG INTERACTIONS

Laboratory Test Interference

Platelet Tests

ADAKVEO interferes with automated platelet counts (platelet clumping) in particular when blood samples are collected in tubes containing EDTA, which may lead to unevaluable or falsely decreased platelet counts. 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.

Warnings & Precautions

WARNINGS

Included as part of the "PRECAUTIONS" Section

PRECAUTIONS

Infusion-Related Reactions

In the SUSTAIN clinical trial, infusion-related reactions (defined as occurring during/within 24 hours of infusion) were observed in 2 (3%) patients treated with ADAKVEO 5 mg/kg [see ADVERSE REACTIONS].

In the postmarketing setting, cases of infusion-related reactions, including severe pain events, have been reported, which required hospitalizations. The majority of these infusion-related reactions occurred during the first and second infusions. The management of pain events has included acetaminophen, 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 for and advise patients of signs and symptoms of infusion-related reactions, which may include pain in various locations, headache, fever, chills, nausea, vomiting, diarrhea, fatigue, dizziness, pruritus, urticaria, sweating, shortness of breath or wheezing.

Discontinue ADAKVEO infusion for severe infusion-related reactions and institute appropriate medical care [see DOSAGE AND ADMINISTRATION].

For management recommendations of a mild or moderate infusion-related reaction [see DOSAGE AND ADMINISTRATION].

Exercise caution with corticosteroids in patients with sickle cell disease unless clinically indicated (e.g., treatment of anaphylaxis).

Laboratory Test Interference

Interference with automated platelet counts (platelet clumping) has been observed following administration of ADAKVEO, in particular, when blood samples were collected in tubes containing ethylenediaminetetraacetic acid (EDTA). Mitigation strategies are recommended [see DRUG INTERACTIONS].

Patient Counseling Information

Advise the patient to read the FDA-approved patient labeling (PATIENT INFORMATION).

Infusion-Related Reactions

Advise patients to contact their healthcare provider immediately for signs or symptoms of infusion-related reactions [see WARNINGS AND PRECAUTIONS].

Interference With Automated Platelet Counts

Advise patients to inform their healthcare provider that they are receiving ADAKVEO prior to any blood tests due to the potential interference with laboratory tests used to measure platelet counts [see WARNINGS AND PRECAUTIONS].

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment Of Fertility

No carcinogenicity or genotoxicity studies have been conducted with crizanlizumab-tmca.

In the 26-week repeat-dose toxicity study, cynomolgus monkeys were administered crizanlizumab-tmca once every 4 weeks at doses up to 50 mg/kg (at least 13.5 times the human clinical exposure based on AUC in patients with sickle cell disease at 5 mg/kg once every 4 weeks). There were no adverse effects of crizanlizumab-tmca on male or female reproductive organs.

Use In Specific Populations

Pregnancy

Risk Summary

Based on data from animal studies, ADAKVEO has the potential to cause fetal harm when administered to a pregnant woman. In an animal reproduction study, intravenous administration of crizanlizumab-tmca to pregnant cynomolgus monkeys from the onset of organogenesis through delivery resulted in a non-dose related increased fetal loss (abortions/stillbirths) at doses approximately 2.8 times the exposure at the recommended clinical dose at 5 mg/kg/dose once every 4 weeks (see Data).

There are insufficient human data on ADAKVEO use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. 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.

The estimated background risk of major birth defects and miscarriage for the indicated population is approximately 14% and up to 43%, respectively. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes.

Clinical Considerations

Disease-Associated Maternal and/or Embryo/Fetal Risk

Women with sickle cell disease have an increased risk of adverse pregnancy outcomes for the mother and the fetus. Pregnant women are at greater risk for VOCs, pre-eclampsia, eclampsia, and maternal mortality. For the fetus, there is an increased risk for intrauterine growth restriction, preterm delivery, low birth weight, and perinatal mortality.

Data

Animal Data

In an enhanced pre-and postnatal development study in cynomolgus monkeys, pregnant animals received intravenous doses of crizanlizumab-tmca at 10 and 50 mg/kg once every 2 weeks during the period of onset of organogenesis through delivery. No maternal toxicity was observed. Maternal exposures at doses of 10 and 50 mg/kg were between 2.8 and 16 times, respectively, the human clinical exposure based on area under the curve (AUC) in patients with sickle cell disease at 5 mg/kg/dose once every 4 weeks. There was an increase in fetal loss (abortions or still births) at both crizanlizumabtmca doses which was higher in the third trimester.

There were no effects on infant growth and development through 6-months postpartum that were attributable to crizanlizumab-tmca.

Measurable crizanlizumab-tmca serum concentrations were observed in the infant monkeys at postnatal Day 28, confirming that crizanlizumab crosses the placental barrier.

Lactation

Risk Summary

There is no data on the presence of crizanlizumab-tmca in human or animal milk, the effects on the breastfed child, or the effects on milk production. Maternal IgG is known to be present in human milk. The effects of local gastrointestinal exposure and limited systemic exposure in the breastfed child to crizanlizumab-tmca are unknown.

The developmental and health benefits of breast-feeding should be considered along with the mother’s clinical need for ADAKVEO and any potential adverse effects on the breastfed child from ADAKVEO or from the underlying maternal condition.

Pediatric Use

The safety and effectiveness of ADAKVEO for sickle cell disease have been established in pediatric patients aged 16 years and older. Use of ADAKVEO for sickle cell disease is supported by evidence from adequate and well-controlled studies in adults and pediatric patients (SUSTAIN Trial). The SUSTAIN trial enrolled one pediatric patient treated with ADAKVEO 5 mg/kg aged 16 years old [see ADVERSE REACTIONS, CLINICAL PHARMACOLOGY, Clinical Studies].

The safety and efficacy of ADAKVEO in pediatric patients below the age of 16 years have not been established.

Geriatric Use

Clinical studies of ADAKVEO did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.

Clinical Pharmacology

CLINICAL PHARMACOLOGY

Mechanism Of Action

Crizanlizumab-tmca is a humanized IgG2 kappa monoclonal antibody that binds to P-selectin and blocks interactions with its ligands, including P-selectin glycoprotein ligand 1 (PSGL-1). Crizanlizumab can also dissociate preformed P-selectin/PSGL-1 complex.

Binding P-selectin on the surface of the activated endothelium and platelets blocks interactions between endothelial cells, platelets, red blood cells, and leukocytes.

Pharmacodynamics

ADAKVEO resulted in a dose-dependent P-selectin inhibition (measured ex vivo) in patients with sickle cell disease and healthy volunteers.

Pharmacokinetics

The pharmacokinetics of crizanlizumab-tmca were evaluated in healthy volunteers and patients with sickle cell disease. The mean crizanlizumab-tmca Cmax, AUClast, or AUCinf increased disproportionally over the dose range of 0.2 to 8 mg/kg (0.04 to 1.6 times the approved recommended dosage) in healthy volunteers. In healthy volunteers administered the 5 mg/kg dose, the mean [coefficient of variation (CV%)] crizanlizumab-tmca Cmax, AUClast, or AUCinf were 0.16 (15.3%) mg/mL, 33.6 (12.6%) mg*hr/mL and 34.6 (13.1%) mg*hr/mL, respectively.

Distribution

The mean (% CV) volume of distribution was 4.26 (25.1%) L after a single crizanlizumab-tmca 5 mg/kg intravenous infusion in healthy volunteers.

Elimination

The mean (% CV) terminal elimination half-life (t_1/2) of crizanlizumab-tmca was 10.6 (20.5%) days and the mean clearance was 11.7 (16.2%) mL/hr at 5 mg/kg doses in healthy volunteers. The mean (% CV) elimination t_1/2 of crizanlizumab-tmca was 7.6 (28.5%) days during dosing interval in patients with sickle cell disease.

Metabolism

Crizanlizumab-tmca is expected to be metabolized into small peptides by catabolic pathways.

Specific Populations

The effect of renal or hepatic impairment on the pharmacokinetics of crizanlizumab-tmca is unknown.

Drug Interaction Studies

Hydroxyurea had no clinically meaningful effect on crizanlizumab-tmca pharmacokinetics in patients in clinical studies.

Animal Toxicology And/Or Pharmacology

In the 26-week repeat-dose toxicity study, administration of crizanlizumab-tmca in cynomolgus monkeys at dose levels up to 50 mg/kg/dose once every 4 weeks resulted in inflammation of the vessels in multiple tissues in 2 out of 10 animals.

Clinical Studies

The efficacy of ADAKVEO was evaluated in patients with sickle cell disease in SUSTAIN [NCT01895361], a 52-week, randomized, multicenter, placebo-controlled, double-blind study. A total of 198 patients with sickle cell disease, any genotype (HbSS, HbSC, HbS/beta⁰-thalassemia, HbS/beta⁺-thalassemia, and others), and a history of 2-10 VOCs in the previous 12 months were eligible for inclusion. Patients were randomized 1:1:1 to ADAKVEO 5 mg/kg (N = 67), ADAKVEO 2.5 mg/kg (N = 66), or placebo (N = 65) administered over a period of 30 minutes by intravenous infusion on Week 0, Week 2, and every 4 weeks thereafter for a treatment duration of 52 weeks. Randomization was stratified by patients already receiving hydroxyurea (Y/N) and by the number of VOCs in the previous 12 months (2 to 4, 5 to 10).

Patients received ADAKVEO (with or without hydroxyurea) and were allowed to receive occasional transfusions and pain medications [i.e., acetaminophen, non-steroidal anti-inflammatory drugs (NSAIDs), and opioids] on an as needed basis.

Patients recruited in the study had complications associated with sickle cell disease and other comorbidities, including a history of acute chest syndrome (18%); pulmonary hypertension (8%); priapism (7%); psychiatric manifestations (25%), including depression and anxiety; hypertension (17%); cholelithiasis (17%). Demographic and other baseline characteristics were similar among the treatment groups (see Table 3).

Abbreviation: VOCs, vasoocclusive crises.

Efficacy was evaluated in the SUSTAIN study by the annual rate of VOCs leading to a healthcare visit. A VOC leading to a healthcare visit was defined as an acute episode of pain with no cause other than a vasoocclusive event that required a medical facility visit and treatment with oral or parenteral opioids, or parenteral NSAIDs. Acute chest syndrome, hepatic sequestration, splenic sequestration, and priapism (requiring a visit to a medical facility) were also considered VOCs.

Patients with sickle cell disease who received ADAKVEO 5 mg/kg had a lower median annual rate of VOC compared to patients who received placebo (1.63 vs. 2.98) which was statistically significant (p = 0.010). Reductions in the frequency of VOCs were observed among patients regardless of sickle cell disease genotype and/or hydroxyurea use.

Thirty-six percent (36%) of patients treated with ADAKVEO 5 mg/kg did not experience a VOC compared to 17% of placebo-treated patients. The median time to first VOC from randomization was 4.1 months in the ADAKVEO 5 mg/kg arm compared to 1.4 months in the placebo.

The main efficacy results of the pivotal study, SUSTAIN, are summarized in Table 4.
