• Positive Cardiac Safety Data for Annamycin

  A pooled analysis across five completed clinical trials demonstrated no detectable cardiotoxicity for Annamycin, even at cumulative exposure levels far exceeding conventional anthracycline limits.

• Independent Validation by Cleveland Clinic

  The cardiac safety findings were independently reviewed by Cleveland Clinic cardiology specialists, providing external validation.

• Reinforces Ongoing Pivotal Trial

  This data strengthens the rationale for the ongoing Phase 2b/3 MIRACLE trial for relapsed/refractory AML, with unblinding of initial data expected in June 2026.

• Addresses Key Anthracycline Limitation

  Annamycin's differentiated cardiac safety profile could allow patients to benefit from anthracycline therapy without the traditional cumulative cardiac burden.

Moleculin Biotech announced positive cardiac safety data for its lead drug candidate, Annamycin, presented at ASCO 2026. A pooled analysis across five clinical trials showed no detectable cardiotoxicity despite high cumulative exposure, a key differentiator for anthracycline-based therapies. This data, independently reviewed by Cleveland Clinic, significantly de-risks Annamycin and strengthens the rationale for the ongoing pivotal Phase 2b/3 MIRACLE trial, which has unblinding expected in June 2026. For a company with a 'going concern' warning and a need for capital, this positive clinical development is crucial for investor confidence and future financing.
