The Lundquist Institute and Its Start-Up Company Vitalex Biosciences Announce Strategic Advancement of Second-Generation Fungal Vaccine VXV-01 Through Phase 1 Trials Under $40 Million Competitive Contract From NIH/NIAID

Los Angeles, California, Nov. 12, 2025 (GLOBE NEWSWIRE) — The Lundquist Institute (TLI) and its start-up company Vitalex Biosciences (Vitalex) are pleased to announce that the second-generation fungal vaccine candidate known as VXV‑01, which was developed using a proprietary TLI vaccine technology platform, is poised to move forward in development up to and including Phase 1 clinical evaluation — enabled by a major contract awarded to a collaboration consortium of Vitalex and Appili Therapeutics (TSX: APLI; OTCPink: APLIF). The contract from the National Institutes of Health’s (NIH) National Institute of Allergy and Infectious Diseases (NIAID) is valued at up to US $40 million. It will support the development of VXV-01 from manufacturing and non-clinical studies through two Phase 1 clinical trials. This contract represents a significant milestone for The Lundquist Institute’s vaccine research program.

Key Highlights

• Vitalex has an exclusive option to license VXV-01 from TLI for commercial development.
• The contract, awarded by NIH/NIAID, provides up to US $40 million of non-dilutive funding to Vitalex and its collaborator Appili and for the comprehensive development of VXV-01.
• VXV-01 is built on the TLI (Therapeutic & Laboratory Immunology) technology platform developed at TLI, a second-generation approach containing two antigens designed to target invasive Candida infections with broader-spectrum cross-kingdom protection potential against Gram-negative healthcare-associated infections.
• With this funding, the program is positioned to begin manufacturing and other preparations necessary to initiate two Phase 1 clinical trials, which, when they occur, will mark a transition from preclinical research into the first stage of human testing.
• Advancing VXV-01 into development up to and including Phase 1 trials brings it one step closer to delivering a novel prophylactic solution for serious fungal infections, a major unmet need in infectious disease.

“Securing this contract is a pivotal moment for our team,” said Ashraf Ibrahim, PhD, Principal Investigator and VXV-01 program lead at TLI and CEO of Vitalex. “By putting VXV-01 into development through human trials, we are significantly increasing our chances of making this vaccine a reality. It is the culmination of years of work on our TLI technology platform and reflects our commitment to tackling high-impact infectious disease challenges.”

About VXV-01
VXV-01 is a dual-antigen fungal vaccine candidate designed to elicit robust immunity against key opportunistic and hospital-associated Candida and Gram-negative bacterial pathogens. Built at TLI and further developed by Vitalex, VXV-01 is engineered for strong immunogenicity, manufacturability and scalability. The move into Phase 1 human trials marks the transition from lab and animal model proof-of-concept to human safety and immunogenicity studies.
