Red Queen Therapeutics is a clinical-stage biotechnology company preparing rapid responses to current and emerging pathogens that threaten human health and life.
Our novel plug-and-play antiviral platform, based on stapled peptide decoys, can be rapidly deployed against pandemic and pandemic-potential viruses, as well as other viruses that cause recurring, untreated disease.
Our name refers to the Red Queen hypothesis in evolutionary biology, which posits that species constantly compete in a race to be predator rather than prey. Red Queen’s novel, patented technology works to outcompete viral evolution, to protect humanity from dangerous illnesses.
Our platform is based on stapled peptides that prevent viral fusion to the host cell membrane, thereby preventing entry of the virus and infection.
These stapled peptide therapeutics can be formulated and delivered in various ways, via nasal spray, inhaler, or injection.
Stapled helical peptide chemistry resolves the shortcomings of peptide therapeutics
2. Insert non-natural
3. Chemically "staple" the peptide
Red Queen’s therapeutics target a conserved sequence area of a virus that is constrained from mutating and conserved across species. This means that they can be used across the entire viral species and against future variants.
Our target is the six-helix bundle fusion mechanism of viral infection.
Structural similarities across targets allow for the rapid deployment of our approach across a range of viral illnesses.

Red Queen has designed a broad antiviral platform and collected preclinical data showing its activity against several virulent diseases.

Potential future products include combination fusion inhibitors in a single spray, and combinations with other antivirals.
Red Queen is currently recruiting people in multiple US locations to participate in a clinical trial of RQ-01, its investigative treatment. RQ-01 is delivered as a nasal spray for the treatment of mild COVID-19. (This is a therapeutic, not a vaccine.)
