Form 8-K Moleculin Biotech, Inc. For: Oct 19

Exhibit 99.1

 

Moleculin Receives Authorization from the Medicines and Healthcare Products Regulatory Agency (MHRA) to Commence Phase 1a Clinical Trial of WP1122 for the Treatment of COVID-19

 

– First-in-human Phase 1a study to evaluate safety and pharmacokinetics of WP1122 in healthy volunteers and establish maximum tolerated dose expected to commence in 4^th Quarter 2021 –

 

– Based on previously announced preclinical data demonstrating its antiviral potential, the Company believes WP1122 may potentially help meet the critical need for a pan-viral therapy that could address not only COVID-19 and its variants, but also future viruses –

 

HOUSTON, October 19, 2021 /PRNewswire/ -- Moleculin Biotech, Inc., (Nasdaq: MBRX) (Moleculin or the Company), a clinical stage pharmaceutical company with a broad portfolio of drug candidates targeting highly resistant tumors and viruses, today announced it has received authorization from the Medicines and Healthcare Products Regulatory Agency (MHRA) to commence a Phase 1a clinical trial of WP1122 in the United Kingdom. WP1122, the Company’s lead metabolism/glycosylation inhibitor, is a prodrug of a well-known antimetabolite called 2-deoxy-D-glucose (2-DG) currently being developed for inhibition of viral replication and disease manifestations in humans infected with SARS-CoV-2, the virus responsible for COVID-19. The Company also announced it has received a favorable opinion from the London - Riverside Research Ethics Committee in the UK to begin the study, which is expected to be conducted at the Medicines Evaluation Unit in Manchester, United Kingdom.

 

“We are incredibly grateful for the ongoing efforts and discussions the MHRA has engaged in with us to advance this important program. Coronaviruses, including SARS-CoV-2, are highly dependent upon glycosylation to form structurally and functionally different essential glycoproteins, as well as glycolysis for energy production. The potent antiviral effect demonstrated by WP1122 in preclinical models to-date is encouraging and bolsters our belief in its potential as an effective therapy for COVID-19," commented Walter Klemp, Chairman and CEO of Moleculin.

 

The Phase 1a study in healthy human volunteers will investigate the effects of a single ascending dose (SAD) and multiple days of ascending dosing (MAD) of WP1122 administered as an oral solution. Dose escalation will take place in sequential SAD cohorts, and MAD will start as soon as SAD has completed at least 3 dosing cohorts in which WP1122 is found to be safe and well-tolerated. This study in healthy volunteers will explore safety and pharmacokinetics (PK), and subsequent clinical development will be in patients infected with SARS-CoV-2 to further evaluate safety and establish a favorable risk/benefit profile. The Company expects to enroll approximately 80 healthy volunteers in the United Kingdom. The primary endpoint (SAD and MAD) for the study is safety and tolerability, which will be assessed by the frequency of adverse events (AEs), serious adverse events, treatment-emergent adverse events, and AEs of special interest. These will be presented by severity and seriousness, system organ class, preferred term and cohort. Clinically significant changes from baseline in clinical laboratory values, physical examination, vital signs, and electrocardiograms will be documented. The secondary endpoint (SAD and MAD) of the study will be the assessment of PK parameters of WP1122 and its 3 active metabolites. Total duration of study participation for each subject will be up to 4 weeks during SAD and up to 5 weeks during MAD.

 

WP1122 was developed as a 2-DG prodrug to provide a more favorable pharmacological profile and was found to have greater potency than 2-DG alone in preclinical models where tumor cells require higher glycolytic activity than normal cells. WP1122 has also been shown to have a more potent antiviral effect than 2-DG against SARS-CoV-2 in MRC-5 cells in culture. The improved pharmacokinetic and pharmacodynamic (PK/PD) profile of WP1122 compared to 2-DG was noted in female mice following oral dosing at equimolar (i.e., equivalent levels of 2-DG) doses.

 

Moleculin Biotech is also in the process of identifying additional countries where potential future Phase 2 COVID-19 clinical studies could occur. The Company is also engaged in preclinical development of additional antimetabolites (WP1096 and WP1097) targeting glycosylation and glycolysis, as well as developing an Investigational New Drug (IND) submission to study WP1122 in cancer patients.

 

About Moleculin Biotech, Inc.

 

Moleculin Biotech, Inc. is a clinical stage pharmaceutical company focused on the development of a broad portfolio of drug candidates for the treatment of highly resistant tumors and viruses. The Company’s lead program, Annamycin is a next-generation anthracycline designed to be noncardiotoxic and to avoid multidrug resistance mechanisms. In addition, Annamycin has been shown in animal models to reach higher concentration levels than doxorubicin (a leading anthracycline) in certain key organs, such as the lungs, liver and pancreas considered to be difficult-to-reach “sanctuary sites” for tumors. Annamycin is currently in development for the treatment of relapsed or refractory acute myeloid leukemia (AML) and soft tissue sarcoma (STS) lung metastases.

 

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, and WP1220, an analog to WP1066, for the topical treatment of cutaneous T-cell lymphoma. Moleculin is also engaged in the development of a portfolio of antimetabolites, including WP1122 for the potential treatment of COVID-19 and other viruses, as well as cancer indications including brain tumors, pancreatic and other cancers.
