Published on Feb. 27, 2026

Moleculin Biotech, Inc., a Phase 3 clinical stage pharmaceutical company, announced that it has entered into agreements with certain holders of its existing warrants to exercise those warrants, raising approximately $8.3 million in gross proceeds. The company will use the funds for working capital and general corporate purposes as it continues development of its pipeline of therapeutic candidates targeting hard-to-treat tumors and viruses.

Why it matters

This capital raise will provide Moleculin with additional resources to advance its clinical programs, including the ongoing MIRACLE trial evaluating its lead drug candidate Annamycin for the treatment of relapsed or refractory acute myeloid leukemia. Securing funding is crucial for a clinical-stage biotech company like Moleculin to continue progressing its pipeline of potential new cancer and antiviral therapies.

The details

The transaction is expected to close on or about February 20, 2026.
