Approval Details and Therapeutic Indication
The tentative approval was granted for the company's Abbreviated New Drug Application (ANDA) for Binimetinib Tablets, 45 mg.

Binimetinib is a kinase inhibitor indicated for the treatment of patients with unresectable or metastatic melanoma with a BRAF V600E or V600K mutation, in combination with encorafenib. It is also indicated for the treatment of adult patients with metastatic non-small cell lung cancer (NSCLC) with a BRAF V600E mutation.
Market Position and Exclusivity
Based on the FDA's Paragraph IV Certifications List, Alembic is the first applicant to have filed its ANDA containing a Paragraph IV certification for this dosage. Consequently, upon final approval, the company may be eligible for 180 days of marketing exclusivity. Alembic had previously received tentative approval for Binimetinib Tablets, 15 mg.
