HOUSTON, November 11, 2024 /PRNewswire/ -- Moleculin Biotech, Inc., (Nasdaq: MBRX) (“Moleculin” or the “Company”), a late stage pharmaceutical company with a broad portfolio of drug candidates targeting hard-to-treat tumors and viruses, today reported its financial results for the quarter ended September 30, 2024. As previously announced, the Company will host a conference call and live audio webcast to discuss the operational and financial results at 8:30 AM ET on Monday, November 11, 2024 (details below).

 

“We are thrilled to have emerged as a late stage company. Our focus remains on the ramp up for and execution of our upcoming MIRACLE trial. We have been extremely active and our recent interactions with potential clinical trial sites globally have been overwhelmingly positive as we prepare for the start of enrollment and dosing early next year. We believe with our recent clinical and regulatory ‘wins,’ we have foundationally set the stage for a transformational year ahead and the opportunity to drive significant value for all stakeholders. With that said, we continue to follow our CRc (complete response composite) preliminary data from our MB-106 Phase 1B/2 AML clinical trial. We are also pleased with the median durability continuing to climb – and is now in excess of 8 months,” commented Walter Klemp, Chairman and Chief Executive Officer of Moleculin.

Clinical Development Update

 

Annamycin is currently being evaluated in ongoing clinical trials for the treatment of relapsed or refractory acute myeloid leukemia (AML) and soft tissue sarcoma (STS) lung metastases. Annamycin currently has Fast Track Status and Orphan Drug Designation from the FDA for the treatment of relapsed or refractory acute myeloid leukemia, in addition to Orphan Drug Designation for the treatment of soft tissue sarcoma. Furthermore, Annamycin has Orphan Drug Designation for the treatment of relapsed or refractory acute myeloid leukemia from the European Medicines Agency (EMA).

 

AML

 

The Company recently announced the positive discussion and outcome of its End of Phase 1B/2 (EOP1B/2) meeting with the US Food and Drug Administration (FDA) supporting the advancement of Annamycin in combination with Cytarabine (also known as “Ara-C” and for which the combination of Annamycin and Ara-C is referred to as “AnnAraC”) to a Phase 3 pivotal trial for the treatment of AML patients who are refractory to or relapsed after induction therapy (R/R AML). This Phase 3 “MIRACLE” trial (derived from Moleculin R/R AML AnnAraC Clinical Evaluation) will be a global trial, including sites in the US.

 

The MIRACLE study, subject to appropriate future filings with and potential additional feedback from the FDA and their foreign equivalents, is expected to initially utilize an adaptive design whereby approximately the first 75 to 90 subjects will be randomized to receive high dose cytarabine (HiDAC) combined with either placebo, 190 mg/m² of Annamycin, or 230 mg/m² of Annamycin. At that point, the trial will be unblinded to select the optimum dose for Annamycin. For the second part of the trial, approximately 240 additional subjects will be randomized to receive either HiDAC plus placebo or HiDAC plus the optimum dose of Annamycin. The selection of the optimum dose will be based not only on the overall balance of safety, tolerability, pharmacokinetics and efficacy, consistent with the FDA’s new Project Optimus initiative.

STS Lung Metastases

 

As previously announced, the Company completed enrollment in the Phase 2 portion of its U.S. Phase 1B/2 clinical trial evaluating Annamycin as monotherapy for the treatment of soft tissue sarcoma lung metastases. Subjects who had stable disease at the time of study discontinuation were followed for progression free response and overall survival. The study database is locked, and the clinical study report is being written and should be completed in early 2025 and will be released in detail at that time

Summary of Financial Results for the Third Quarter 2024

 

Research and development (R&D) expense was $4.9 million and $3.3 million for the three months ended September 30, 2024 and 2023, respectively. The increase over the prior year period is mainly related to costs incurred for clinical trials (clinical research organization and drug production) and sponsored research costs.

 

General and administrative expense was $2.2 million and $2.6 million for the three months ended September 30, 2024 and 2023, respectively. The decrease of $0.4 million is mainly related to a decrease in regulatory and legal fees.

 

As of September 30, 2024, the Company had cash and cash equivalents of $9.4 million and believes that the existing cash and cash equivalents as of September 30, 2024, will be sufficient to fund planned operations into the first quarter of 2025.

About Moleculin Biotech, Inc.

 

Moleculin Biotech, Inc. is a Phase 3 clinical stage pharmaceutical company advancing a pipeline of therapeutic candidates addressing hard-to-treat tumors and viruses. The Company’s lead program, Annamycin, is a next-generation anthracycline designed to avoid multidrug resistance mechanisms and to eliminate the cardiotoxicity common with currently prescribed anthracyclines. Annamycin is currently in development for the treatment of relapsed or refractory acute myeloid leukemia (AML) and soft tissue sarcoma (STS) lung metastases.

 

The Company is initiating the MIRACLE (Moleculin R/R AML AnnAraC Clinical Evaluation) Trial (MB-108), a pivotal, adaptive design Phase 3 trial evaluating Annamycin in combination with cytarabine, together referred to as AnnAraC, for the treatment of relapsed or refractory acute myeloid leukemia. Following a successful Phase 1B/2 study (MB-106), with input from the FDA, the Company believes it has substantially de-risked the development pathway towards a potential approval for Annamycin for the treatment of AML. This study is subject to appropriate future filings with potential additional feedback from the FDA and their foreign equivalents.

 

Additionally, the Company is developing WP1066, an Immune/Transcription Modulator capable of inhibiting p-STAT3 and other oncogenic transcription factors while also stimulating a natural immune response, targeting brain tumors, pancreatic and other cancers. Moleculin is also engaged in the development of a portfolio of antimetabolites, including WP1122 for the potential treatment of pathogenic viruses, as well as certain cancer indications.
