Health Holland Awards Innovative Research Grant for DNA Pol IIIC Inhibitors to Leiden University Medical Center and Acurx Pharmaceuticals
Acurx Pharmaceuticals (Nasdaq: ACXP) announced a $500,000 grant from Health Holland to support a collaborative research project with Leiden University Medical Center. This project aims to explore the structure of DNA polymerase C from multi-drug resistant bacteria, enhancing the development of new antibiotics. Acurx will begin a Phase 2b clinical trial for Clostridioides difficile Infection (CDI) in late 2021, following promising results from an earlier trial where 100% of patients achieved primary efficacy endpoints. The research may lead to innovative treatments for serious Gram-positive pathogens.
- Received a $500,000 grant from Health Holland to fund antibiotic research.
- Phase 2a clinical trial for CDI showed 100% efficacy in patients.
- Research may lead to novel inhibitors targeting multi-drug resistant bacteria.
- None.
STATEN ISLAND, N.Y., Aug. 2, 2021 /PRNewswire/ -- Acurx Pharmaceuticals, Inc. (Nasdaq ACXP) ("Acurx" or the "Company") a clinical stage biopharmaceutical company developing a new class of antibiotics for difficult-to-treat bacterial infections, announced today that Health Holland has awarded a grant of approximately
Dr.Wiep Klaas Smits, Associate Professor, LUMC Department of Medical Microbiology will be the lead researcher in collaboration with Dr. Meindert Lamers, Associate Professor, LUMC Department of Cell and Chemical Biology.
Dr. Smits stated: "This collaborative grant opportunity will be a novel scientific accomplishment contributing to Acurx programs by enhancing knowledge of the structure of pol IIIC from different pathogenic, multidrug-resistant organisms. Additionally, we will study the binding of Acurx drug candidates in complex with pol IIIC enzymes to establish a detailed in vitro characterization of polymerase and inhibiting activity." He further stated: "This work will lead to important insights into differences between replicative polymerases of critical drug-resistant Gram-positive pathogens and pave the way for rational design of novel inhibitors based on structure-activity relationships in the future."
Acurx is commencing a Ph2b clinical trial in patients with CDI during the second half of this year after having recently completed a Ph2a clinical trial which demonstrated that 10 of 10 patients with CDI (
Robert J. DeLuccia, Executive Chairman of Acurx, stated "We believe this state-of-the-art structural biology research, which includes crystallography and cryo-electron microscopy, can be translated into chemical synthesis strategies to develop an innovative portfolio of novel inhibitors of DNA polymerases of target organisms with our GPSS™ (Gram-positive Selective Spectrum) antibiotic candidates". He further stated: "This could lead to identification of selective inhibitors for serious Gram-positive pathogens, particularly MRSA, VRE and PRSP, offering more opportunities to enhance our development pipeline and to expand the treatment options with new classes of antibiotics for multi-drug resistant bacterial infections."
*"pol C" is alternative nomenclature for "pol IIIC"
About the Research Project, Leiden University Medical Center, the Research Consortium
Antimicrobial resistant microorganisms are a major threat to global health and pose a significant economic burden. Increasing resistance to multiple agents and resistance to so called last-resort antibiotics underscore the necessity to develop therapeutics that have a novel mode of action. DNA replication is a process that can be successfully targeted by small molecules. Ibezapolstat, an inhibitor of the replicative DNA polymerase pol IIIC from Gram-positive bacteria identified by screening library of dGTP analogues, has shown promising results for the treatment of Clostridioides difficile Infection in a recent Phase 2a clinical trial, but the molecular basis of selective inhibition is not fully characterized as no structural information is available on pol IIIC proteins from pathogens. This research project will determine the structure of pol IIIC from the multidrug-resistant organisms methicillin resistant Staphylococcus aureus (MRSA), vancomycin resistant Enterococci (VRE) and/or penicillin resistant Streptococcus pneumoniae (PRSP) in the absence and presence of lead compounds. These results will reveal the structural space of inhibitor-binding and guide the rational design of inhibitors with optimal pharmacological properties and organism-specificity that will be demonstrated by in vitro polymerase inhibition assays and in vivo minimal inhibitory concentration determination.
Leiden University was the first university to be established in the Netherlands. Its motto is praesidium libertatis – bastion of freedom. The University wishes to create an increasingly attractive and challenging working climate for top academics and young researchers that is guided by quality and excellence. Leiden University Medical Center (LUMC) research aims to meet the highest international standards of quality and academic integrity. LUMC promotes excellent research through greater collaboration, both disciplinary and interdisciplinary; stronger positioning and greater scope for top talent; and better supervision and more support for young researchers.
The Research Consortium participants are the Dutch Top Sector Life Sciences and Health ('Topconsortium voor Kennis en Innovatie' or 'TKI' Life Sciences and Health) and is represented by Stichting Life Sciences Health – TKI (aka, Health~Holland) and is tasked by the Dutch government to promote and stimulate new public-private partnerships (PPPs) to undertake R&D projects in the life sciences. To promote such partnerships, the Minister of Economic Affairs and Climate Policy has allocated certain funds to Stichting LSH-TKI, to grant allowances to projects under the TKI-programme Life Sciences & Health. Stichting LSH-TKI has designated the Board of Directors of LUMC as delegated grantor for the PPP allowance allocated to the LUMC.
Together with Acurx Pharmaceuticals the PPP will initiate the research project entitled "Bad bugs, new drugs: elucidation of the structure of DNA polymerase C of multidrug resistant bacteria in complex with novel classes of antimicrobials." The collaboration project is co-funded by the PPS Allowance made available by Health~Holland, Top Sector Life Sciences & Health, to stimulate public-private partnerships.
About Clostridioides difficile Infection (CDI).
According to the 2017 Update (published February 2018) of the Clinical Practice Guidelines for C. difficile Infection by the Infectious Diseases Society of America (IDSA) and Society or Healthcare Epidemiology of America (SHEA), CDI remains a significant medical problem in hospitals, in long-term care facilities and in the community. C. difficile is one of the most common causes of health care-associated infections in U.S. hospitals (Lessa, et al, 2015, New England Journal of Medicine). Recent estimates suggest C. difficile approaches 500,000 infections annually in the U.S. and is associated with approximately 20,000 deaths annually. (Guh, 2020, New England Journal of Medicine). Based on internal estimates, the recurrence rate of two of the three antibiotics currently used to treat CDI is between
The U.S. Center for Diseases Control 2019 Update on Antimicrobial Resistance. https://www.cdc.gov/drugresistance/pdf/threats-report/2019-ar-threats-report-508.pdf . CDC reported that more than 2.8 million antibiotic-resistant infections occur in the U.S. each year and more than 35,000 people die as a result, nearly twice as many annual deaths than previously reported by CDC in 2013. These deaths are attributed to antimicrobial-resistant pathogens including Enterococcus (including vancomycin-resistant strains or VRE), Staphylococcus (including methicillin-resistant strains or MRSA), and Streptococcus (including antibiotic-resistant strains), which are the bacterial targets of the Company's antibiotic pipeline with its GPSS™ (Gram-Positive Selective Spectrum) in preclinical development and also potentially eligible for QIDP and FDA-Fast-Track-Designation for priority review.
