Moleculin secures two new US patents for cancer drug Annamycin

HOUSTON - Moleculin Biotech, Inc. (NASDAQ:MBRX), a late-stage pharmaceutical company with a market capitalization of $14.4 million, announced today the issuance of two additional U.S. patents for Annamycin, its novel drug candidate targeting certain cancers, including acute myeloid leukemia (AML) and soft tissue sarcoma lung metastases (STS lung mets). According to InvestingPro analysis, the company maintains a favorable cash-to-debt position, though it faces significant challenges with rapid cash burn. The patents granted by the U.S. Patent and Trademark Office (USPTO) extend the intellectual property protection for Annamycin until June 2040, with potential adjustments for regulatory approval timelines.

The patents, numbers 12,257,261 and 12,257,262, cover the preparation and reconstitution methods for liposomal Annamycin, a formulation designed to mitigate the cardiotoxicity often associated with anthracyclines, a class of chemotherapy drugs. Annamycin has been granted Fast Track Status and Orphan Drug Designation by the FDA for the treatment of relapsed or refractory AML and STS lung mets, as well as similar designations from the European Medicines Agency (EMA). Analyst price targets for MBRX range from $4 to $20, reflecting significant potential upside despite recent market volatility.

Wally Klemp, Chairman and CEO of Moleculin, stated the company’s commitment to advancing Annamycin as a treatment option, highlighting ongoing progress in the Phase 3 MIRACLE trial, with initial data expected in the second half of 2025.

Annamycin’s development is part of Moleculin’s broader pipeline, which includes WP1066, an Immune/Transcription Modulator for brain tumors and other cancers, and WP1122, an antimetabolite for viral infections and certain cancers.

This announcement is based on a press release statement. Moleculin’s ability to conduct clinical trials and achieve milestones as described is contingent upon securing additional financing, for which there are currently no commitments. The company has cautioned that forward-looking statements are subject to risks and uncertainties, and actual results may differ materially from those projected. With the next earnings report due on May 9, 2025, InvestingPro subscribers can access detailed financial health metrics, including cash flow analysis and profitability scores, to better assess investment risks. The company currently shows weak financial health scores and negative EBITDA of -$26.5 million for the last twelve months.

In other recent news, Moleculin Biotech has been actively advancing its clinical trials and financial strategies. The company is preparing for a pivotal Phase 3 trial of its drug Annamycin, targeting acute myeloid leukemia (AML), with plans to enroll the first patient in the first quarter of 2025. Moleculin’s recent earnings call highlighted a reduction in operating expenses by $3 million in 2024, with a current cash balance of $13 million expected to last until the third quarter of 2025. H.C. Wainwright has maintained its Buy rating on Moleculin Biotech, with a price target of $8, citing the potential of the MIRACLE trial and the company’s progress in clinical site selection.

Additionally, Moleculin disclosed findings at the American Association for Cancer Research Annual Meeting, showing that Annamycin works synergistically with other anticancer therapies. The company’s Special Meeting of Stockholders was adjourned due to a lack of quorum, with plans to reconvene on April 25, 2025. Moleculin’s broader pipeline includes other promising candidates like WP1066 and WP1122, which are targeting various cancers and viruses. The company faces challenges typical of clinical-stage pharmaceutical companies, including financial constraints and the high costs of clinical trials. However, the strategic advancements in their clinical trials and financial management indicate a focused effort to achieve significant milestones in the near future.
