Bristol-Myers Squibb Company today announced that the U.S. Food and Drug Administration (FDA) has approved a supplemental new drug application (sNDA) for SUSTIVA ® (efavirenz), including dosing recommendations for HIV-1 infected pediatric patients three months to three years old and weighing at least 3.5 kg. This approval offers a once-daily option as part of a regimen for this population and includes a “capsule sprinkle” administration method for patients who cannot swallow capsules or tablets. Detailed information about the “capsule sprinkle” method is provided in the ‘Instructions for Use’ at the end of the Patient Information section of the Package Insert.
SUSTIVA is a non-nucleoside reverse transcriptase inhibitor (NNRTI) that was originally approved in the U.S. in 1998 to treat HIV-1 infected children three years of age or older and weighing at least 10 kg. SUSTIVA is not to be taken by patients who are allergic to efavirenz, or to any of its ingredients.
“Bristol-Myers Squibb recognizes the importance of offering alternative methods of administration of HIV medicines, including for pediatric patients who cannot swallow tablets or capsules, and their caregivers who help manage their treatment,” said Brian Daniels, M.D., Senior Vice President, Global Development and Medical Affairs. “This approval is one example of our enduring commitment to the HIV patient community.”
This sNDA was based on results from three open-label studies that evaluated the pharmacokinetics, safety, and antiretroviral activity of SUSTIVA in combination with other antiretroviral agents in 182 antiretroviral-naïve and –experienced HIV-1 infected pediatric patients (three months to 21 years of age) for a median of 123 weeks. Virologic and immunologic response was observed across all ages at the end of the studies, as measured by HIV RNA and CD4 cell count.
The adverse reactions observed in the three pediatric trials were similar to those observed in clinical trials in adults, except that rash was more common in pediatric patients (32 percent for all grades regardless of causality) and more often of higher grade (i.e., more severe). Five pediatric patients (2.7 percent) discontinued from the study because of rash. Use of SUSTIVA (efavirenz) in patients younger than three months of age OR less than 3.5 kg body weight is not recommended because the safety, pharmacokinetics and antiretroviral activity of SUSTIVA have not been evaluated in this age group and there is a risk of developing HIV resistance if SUSTIVA is underdosed.
