NIKTIMVO Important Safety Information
WARNINGS AND PRECAUTIONS
Infusion-Related Reactions
Niktimvo™ (axatilimab-csfr) can cause infusion-related reactions. Infusion-related
reactions, including hypersensitivity reactions, occurred in 18% of patients who
received Niktimvo in the clinical trial (AGAVE-201), with Grade 3 or 4 reactions in
1.3%.
Premedicate with an antihistamine and an antipyretic for patients who have
previously experienced an infusion-related reaction to Niktimvo. Monitor patients
for signs and symptoms of infusion-related reactions, including fever, chills, rash,
flushing, dyspnea, and hypertension. Interrupt or slow the rate of infusion or
permanently discontinue Niktimvo based on the severity of the reaction.
Embryo-Fetal Toxicity
Based on its mechanism of action, Niktimvo may cause fetal harm when
administered to a pregnant woman. Advise pregnant women of the potential risk to
the fetus. Advise females of reproductive potential to use effective contraception
during treatment with Niktimvo and for 30 days after the last dose.
ADVERSE REACTIONS
Serious adverse reactions occurred in 44% of patients who received Niktimvo
(N=79). Serious adverse reactions in > 2 patients included infection (pathogen
unspecified) (14%), viral infection (14%), and respiratory failure (5.1%). Permanent
discontinuation of Niktimvo due to an adverse reaction occurred in 10% of patients
and dose reduction due to adverse reaction occurred in 8% of patients. Dose
interruptions due to an adverse reaction occurred in 44% of patients. The adverse
reactions leading to dose interruption in > 2 patients were viral infection, infection
(pathogen unspecified), bacterial infection, musculoskeletal pain, and pyrexia.
The most common (≥ 15%) adverse reactions, including laboratory abnormalities,
were increased aspartate aminotransferase (AST), infection (pathogen unspecified),
increased alanine aminotransferase (ALT), decreased phosphate, decreased
hemoglobin, viral infection, increased gamma glutamyl transferase (GGT),
musculoskeletal pain, increased lipase, fatigue, increased amylase, increased
calcium, increased creatine phosphokinase (CPK), increased alkaline phosphatase
(ALP), nausea, headache, diarrhea, cough, bacterial infection, pyrexia, and dyspnea.
Clinically relevant adverse reactions in < 10% of patients who received Niktimvo
included:
• Eye disorders: periorbital edema |
• Skin and subcutaneous disorders: pruritus |
• Vascular disorders: hypertension |
Immunogenicity: Anti-Drug Antibody-Associated Adverse Reactions
Across treatment arms in patients with cGVHD who received Niktimvo in clinical
trials, among the patients who developed anti-drug antibodies (ADAs),
hypersensitivity reactions occurred in 26% (13/50) of patients with neutralizing
antibodies (NAb) and in 4% (2/45) of those without NAb.
USE IN SPECIFIC POPULATIONS
Lactation
Because of the potential for serious adverse reactions in a breastfed child, advise
women not to breastfeed during treatment and for 30 days after the last dose of
Niktimvo.
Females and Males of Reproductive Potential
Pregnancy Testing
Verify pregnancy status in females of reproductive potential prior to initiating
Niktimvo.
Contraception
Females
Advise females of reproductive potential to use effective contraception during
treatment with Niktimvo and for 30 days after the last dose of Niktimvo.
DOSAGE AND ADMINISTRATION
Dosage Modifications for Adverse Reactions
Monitor aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline
phosphatase (ALP), creatine phosphokinase (CPK), amylase, and lipase prior to the
start of Niktimvo therapy, every 2 weeks for the first month, and every 1 to 2 months
thereafter until abnormalities are resolved. See Table 1 in the Prescribing Information
for more recommendations.
