Vical and Mycoses Study Group Education and Research Consortium Establish Collaboration to Advance Vical’s Novel Antifungal VL-2397 for the Treatment of Invasive Aspergillosis

SAN DIEGO, Feb. 01, 2018 (GLOBE NEWSWIRE) -- Vical Incorporated (Nasdaq:VICL) and the Mycoses Study Group Education and Research Consortium (MSGERC) today announced the establishment of a collaboration to advance Vical’s novel antifungal drug product candidate for the treatment of invasive aspergillosis. This collaboration will combine the clinical development expertise of Vical with the specialized expertise of the MSGERC in the area of invasive fungal infections.

“We are excited to establish this collaboration with the world’s leading mycology clinicians and thought leaders,” said Dr. Mammen “Anza” Mammen, Vical’s Senior Vice President, Clinical Development. “We believe the MSGERC will add substantial value to our VL-2397 antifungal program by serving as advisors to our Phase 2 trial and helping provide exposure for the study among their member clinicians who may be interested in taking part as investigators.”

The U.S. Food and Drug Administration (FDA) has advised that VL‑2397 would be eligible for a Limited Use Indication (LUI) approval assuming a successful outcome of a single Phase 2 trial carried out in accordance with a protocol and statistical analysis plan consistent with the Agency's advice. The final determination whether the drug is approvable will be made by FDA after review of all relevant data.

The LUI is a provision of the Limited Population Pathway established under the 21st Century Cures Act of 2016. Vical plans to initiate a single Phase 2 trial for the treatment of invasive aspergillosis in acute leukemia patients and allogeneic hematopoietic cell transplant (HCT) recipients in the first quarter of 2018.

About VL-2397
VL-2397 is Vical’s novel antifungal compound that was licensed from Astellas Pharma in 2015. VL-2397 was isolated from a leaf litter fungus collected in a Malaysian national park and represents the first agent in a potentially new class of antifungal drugs. The FDA has granted Vical Qualified Infectious Disease Product (QIDP), Orphan Drug and Fast Track designations for VL-2397 in the treatment of invasive aspergillosis.

About Invasive Aspergillosis
Invasive aspergillosis is a life-threatening infection that typically affects immunocompromised patients, including those with acute leukemia and recipients of allogeneic HCT or lung transplants. Infection typically starts in the lungs and rapidly disseminates to other tissues. More than 200,000 cases of invasive aspergillosis are diagnosed annually worldwide.
