6.1 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.
In the VYONDYS 53 clinical development program, 58 patients received at least one intravenous dose of VYONDYS 53, ranging between 4 mg/kg (0.13 times the recommended dosage) and 30 mg/kg (the recommended dosage).
All patients were male and had genetically confirmed Duchenne muscular dystrophy.
Age at study entry was 6 to 13 years.
Most (86%) patients were Caucasian.
VYONDYS 53 was studied in 2 double-blind, placebo-controlled studies.
In Study 1 Part 1, patients were randomized to receive once-weekly intravenous infusions of VYONDYS 53 (n=8) in four increasing dose levels from 4 mg/kg to 30 mg/kg or placebo (n=4), for at least 2 weeks at each level.
5 WARNINGS AND PRECAUTIONS Hypersensitivity Reactions: Hypersensitivity reactions, including anaphylaxis, rash, pyrexia, pruritus, urticaria, dermatitis, and skin exfoliation have occurred in patients who were treated with VYONDYS
If a hypersensitivity reaction occurs, institute appropriate medical treatment and consider slowing the infusion, interrupting or discontinuing the VYONDYS 53 therapy.
( 2.3 , 4 , 5.1 ) Kidney Toxicity: Based on animal data, may cause kidney toxicity.
Kidney function should be monitored;
creatinine may not be a reliable measure of renal function in DMD patients.
Like all medications, Vyondys 53 can cause side effects. However, not everyone who takes this medication will experience them. Many side effects are dose-dependent and may improve as your body adjusts to the medication. Others may require dose adjustment or medical attention.
