Strategic Government Funding Pipeline
"Strategic government partnerships are foundational to Appili's impact in infectious disease and biodefense," said Dr. Don Cilla, President and CEO of Appili. "The recent award of up to US$40 million for VXV-01 (search), developed in collaboration with Vitalex Biosciences (search), highlights the confidence the NIAID (search) placed in our execution, and empowers us to accelerate the development of much-needed solutions for urgent public health threats."
The company has submitted multiple funding proposals to U.S. government agencies representing approximately $90 million in potential awards. These proposals would support critical development activities including manufacturing optimization, preclinical studies, regulatory activities, IND submissions, and Phase 1 clinical trials. Appili anticipates awards from multiple proposals may be announced in the first quarter of calendar 2026.

Under the executed agreement with Vitalex, Appili holds an exclusive option to acquire worldwide rights to the VXV-01 program, which would enable control over development, commercialization, and partnering activities.
Commercial Progress with LIKMEZ
Saptalis Pharmaceuticals (search), Appili's manufacturing and commercialization partner, successfully re-launched LIKMEZ (metronidazole oral suspension, 500 mg/5 mL) in the U.S. market as the first and only FDA-approved liquid oral formulation of metronidazole.

Under the partnership terms, Appili is eligible to receive both milestone payments and ongoing royalties from LIKMEZ sales in the U.S., creating a growing source of commercial revenue.
Biodefense Vaccine Advances
ATI-1701, a live-attenuated vaccine candidate for tularemia (search), achieved key operational milestones during the quarter with successful GMP manufacture of drug substance and drug product at its contract manufacturing organization. The GMP drug product may be used in a Phase 1 clinical trial.
In September 2025, Dr. Carl Gelhaus presented new ATI-1701 data at the NATO Chemical, Biological, Radiological and Nuclear Conference, showcasing its promise as a first-in-class tularemia (search) vaccine for biodefense. A new peer-reviewed publication co-authored by Dr. Gelhaus demonstrated ATI-1701's durable protection in primate models, further advancing its momentum as a leading biodefense candidate.
