SAN JOSE, Calif., Sept. 11, 2015 /PRNewswire/ -- Aridis Pharmaceuticals, Inc., a biopharmaceutical company applying proprietary technologies to produce novel anti-infectives and immunotherapies for infectious diseases, announced today that the U.S. Food and Drug Administration (FDA) granted Fast Track Designation to AR-301, the Company’s fully human anti-Staphylococcal alpha-toxin IgG1 monoclonal antibody (mAb). AR-301 is currently in Phase 2a clinical trial for the treatment of hospital-acquired and ventilator-associated pneumonia (HAP and VAP) caused by Staphylococcus aureus, including multi-drug resistant “MRSA” strains.
Vu Truong, Ph.D., Founder and CEO of Aridis, stated, “This is our second product candidate to receive FDA Fast Track designation this year, which provides an accelerated development and regulatory review pathway. Together with Aerucin, our broadly active human IgG1 mAb against P. aeruginosa, these innovative mAbs provide a significant opportunity to improve patient outcomes from potentially life-threatening infections caused by two of the most common and difficult to treat pathogens. We recently expanded our ongoing Phase 2 trial of AR-301 into the U.S. and expect to complete patient enrollment in the first half of 2016, and in parallel, our Phase 1 trial of Aerucin remains on track for completion in the fourth quarter of this year. We look forward to achieving these significant milestones as we continue to execute our clinical development strategy.”
Fast Track designation is a process designed to facilitate the development, and expedite the review of drugs to treat serious conditions and fill unmet medical needs. Companies that receive Fast Track designation are allowed to submit New Drug Applications (NDA) or Biologics License Applications (BLA) on a rolling basis, expediting the FDA review process, and benefiting from more frequent communication with the FDA to discuss all aspects of clinical development. Additionally, drugs that receive Fast Track designation are eligible for accelerated approval and priority review.
About AR-301
AR-301 is a fully human immunoglobulin G1, or IgG1, mAb targeting Gram-positive Staphylococcus aureus, or S. aureus, bacteria, including methicillin-resistant S. aureus (MRSA), which is currently in a Phase 2a clinical trial in HAP and VAP patients. The clinical study is a randomized, double-blind, placebo-controlled study in 52 patients comparing the safety and efficacy of AR-301 as adjunctive therapy with standard-of-care antibiotics versus antibiotics alone. AR-301 is designed to be effective on bacterial infections whether or not they are resistant to conventional antibiotics. AR-301 has already demonstrated strong prophylactic and therapeutic efficacy in mouse models of S. aureus pneumonia and has also been granted Orphan Drug designation in the European Union (EU).
About Acute Pneumonia Due to S. aureus
HAP/VAP due to methicillin-resistant Staphylococcus aureus (MRSA) infections results in substantial loss of life with an annual US/EU/Japan incidence of approximately 523,000 patients and mortality rates as high as 50% depending on the patient population and treatment regimen (Methicillin-Resistant Staphylococcus Aureus, Decision Resources, November 2010). Infections due to MRSA represent a high-value segment of the overall antibiotics market, which is projected to continue expanding. According to this report, the worldwide market for existing therapies for MRSA infections was $630 million in 2009 and is projected to increase to $752 million by 2019. This increase will be driven partly by the progressively aging population, which is expected to increase the number of MRSA infections that result in HAP. Moreover, MRSA infections are associated with significantly longer hospital stays, repeated hospitalizations and increased healthcare costs. Currently, the average hospital stay of a patient with HAP/VAP is ten to 20 days, and the average length of ICU stay is five to ten days. Aridis believes the economic impact of HAP can be calculated in terms of an average cost-of-hospital stay of $25,000 to $50,000.
