Spectrum BLA for Rolontis Withdrawn After FDA Request
Spectrum Pharmaceuticals has withdrawn a BLA for Rolontis (eflapegrastim), a treatment for chemotherapy-induced neutropenia in patients undergoing myelosuppressive chemotherapy, after FDA requested additional manufacturing-related information. The company says it plans to submit a revised BLA as soon as possible.
FDA’s review did not cite concerns related to the pre-clinical and clinical modules of the BLA or the need for additional clinical studies, Spectrum says.
