Moleculin Biotech announced it is approaching the first unblinding of data from its pivotal Phase 2B/3 "MIRACLE" trial evaluating Annamycin in combination with cytarabine for the treatment of subjects with relapsed or refractory acute myeloid leukemia. "The data coming from MIRACLE is encouraging," said Walter Klemp, chairman and CEO of Moleculin. "Against this backdrop, the data emerging from MIRACLE highlight what could be a substantial advancement, suggesting that we may finally be moving beyond the limitations that have defined standard-of-care outcomes". The company continues to expect this unblinding to occur prior to June 30. Preliminary blinded efficacy data for the first 45 subjects continues to approximate a composite complete remission rate exceeding 40% and a complete remission rate of approximately 30%.

About MBRX
Moleculin Biotech, Inc. is a Phase III clinical-stage pharmaceutical company advancing a pipeline of therapeutic candidates addressing tumors and viruses. The Company is conducting a pivotal Phase III trial evaluating Annamycin, a non-cardiotoxic anthracycline, in combination with Cytarabine for the treatment of subjects with relapsed/refractory acute myeloid leukemia (AML). It has three core technologies and six drug candidates, three of which have shown human activity in clinical trials. Its core technologies consist of Annamycin, WP1066 Portfolio, and WP1122 Portfolio. Annamycin is designed to avoid multidrug resistance mechanisms and cardiotoxicity. Its WP1066, is an Immune/Transcription Modulator capable of inhibiting p-STAT3 and other transcription factors, and its portfolio includes WP1193, and WP1220. Its WP1122 contains compounds including WP1096, and WP1097, which is designed to exploit the potential uses of inhibitors of glycolysis such as 2-deoxy-D-glucose (2-DG).

Moleculin Biotech's Annamycin Shows Strong Potential in AML Treatment
- High Prescribing Likelihood: Oncologists reported an average likelihood-to-prescribe score of 6 out of 7 for Annamycin, indicating strong enthusiasm for its potential in treating acute myeloid leukemia (AML), particularly for deep remissions and bridging to transplants.
- Significant Unmet Need: Despite advancements in targeted therapies, the survey revealed that R/R AML patients face substantial treatment gaps, especially those without actionable mutations, suggesting Annamycin's broad applicability could address this unmet need.
- Notable Safety Advantage: Physicians highlighted Annamycin's reduced cardiotoxicity as a critical differentiator, enabling the possibility of repeat dosing, which is particularly relevant for pediatric AML patients concerned about long-term survivorship due to traditional anthracycline limitations.
- Strong Payer Support: Insights from hospital administrators and insurers indicate that Annamycin's efficacy and safety profile are recognized, suggesting it could provide a compelling value proposition for a broad patient population, thereby enhancing its market acceptance.
