Company context

We are a late-stage pharmaceutical development company currently evaluating Annamycin, also known as L-Annamycin and by its generic name “naxtarubicin”, which we believe is a “next-generation” anthracycline and, with it, are conducting a pivotal Phase 2/3 trial in combination with cytarabine for the treatment of subjects with relapsed/refractory (R/R) acute myeloid leukemia (AML). We call this the “MIRACLE” trial (derived from Moleculin R/R AML AnnAraC Clinical Evaluation). A blinded preliminary data readout has been released for the MIRACLE trial, we released an interim unblinding of data in June 2026, and we expect an additional unblinding at the end of 2026, thereby concluding Part A of the two-part trial. We believe such early visibility for a pivotal registration-enabling trial is unique in that stakeholders will receive preliminary safety and efficacy data long before the conclusion of the trial.
