Virpax is developing branded, non-addictive pain management products candidates using its proprietary technologies to optimize and target drug delivery. Virpax is initially seeking FDA approval for two prescription drug candidates that employ two different patented drug delivery platforms. Probudur™ is a single injection liposomal bupivacaine formulation being developed to manage post-operative pain and Envelta™ is an intranasal molecular envelope enkephalin formulation being developed to manage acute and chronic pain, including pain associated with cancer. Virpax is also using its intranasal Molecular Envelope Technology (MET)) to develop two other product candidates. PES200 is a product candidate being developed to manage post-traumatic stress disorder (PTSD) and NobrXiol™ is a product candidate being developed for the nasal delivery of a pharmaceutical-grade cannabidiol (CBD) for the management of rare pediatric epilepsy. Virpax recently acquired global rights to NobrXiol. Virpax is also seeking approval of two nonprescription product candidates: AnQlar, which is being developed to inhibit viral replication caused by influenza or SARS-CoV-2, and Epoladerm™, which is a topical diclofenac spray film formulation being developed to manage pain associated with osteoarthritis.
