Petition Seeks FDA Leukeran Actions
A Buchanan Ingersoll & Rooney 2/6 petition asks FDA to take two specific actions regarding Leukeran (chlorambucil) 2 mg tablets, indicated to treat some leukemias and lymphomas. The petition specifically asks that FDA:
- maintain and strictly apply the requirements of the current product-specific guidance for chlorambucil, which represents scientifically appropriate standards for this class of drugs (oral chemotherapeutic dosage forms), to all pending, newly submitted, and future ANDAs for chlorambucil tablets; and
- pursuant to FDA’s biopharmaceutics classification system, refrain from granting a waiver of the requirement to perform in vivo bioequivalence testing for any generic formulation of chlorambucil.
