FDA OKs Pfizer’s Bosulif for Pediatric CML
FDA has approved a new indication for Pfizer’s Bosulif (bosutinib) for pediatric patients age one and older with chronic phase Ph+ chronic myelogenous leukemia that is newly diagnosed or resistant or intolerant to prior therapy. The agency says it also approved a new capsule dosage form available in 50 mg and 100 mg strengths.
The FDA statement says the drug’s efficacy in this population was evaluated in the BCHILD trial of 28 patients treated with Bosulif.
The most common adverse reactions in pediatric patients were diarrhea, abdominal pain, nausea, rash, fatigue, hepatic dysfunction, headache, pyrexia, decreased appetite, and constipation. The most common laboratory abnormalities that worsened from baseline in pediatric patients were increased creatinine, increased alanine aminotransferase or aspartate aminotransferase, decreased white blood cell count, and decreased platelet count.
The review used the FDA Oncology Center of Excellence Assessment Aid, a voluntary submission from an applicant to facilitate the agency’s assessment. The application was granted priority review and orphan drug designation.
