Clinical Trial Summary

This is a Phase 1, multi-center, randomized, double-blinded, placebo-controlled single (SAD) and multiple ascending (MAD) ascending dose study to assess the safety, tolerability, and pharmacokinetics (PK) of IGM-6268 administered intranasally and intraorally in healthy volunteers. IGM-6268 or placebo will be administered by intranasal + intraoral spray using a Teleflex Mucosal Atomization Device Nasalâ„¢ Intranasal Mucosal Atomization Device once (SAD), or once or twice each day for 5 days (MAD).


Clinical Trial Description

IGM-6268 is an engineered Immunoglobulin M (IgM) antibody that specifically targets the receptor binding domain (RBD) of the SARS-CoV-2 spike protein. This humanized pentameric IgM antibody has 10 binding sites to the spike protein and a J-chain to enable the formation of IgM pentamers. IGM-6268 is being developed as a treatment for or prophylaxis of symptoms associated with mild to moderate COVID-19. The primary mechanism of action of IGM-6268 is to block the binding of the SARS-CoV-2 RBD on the spike protein to human angiotensin converting enzyme 2 (hACE2), the cellular receptor for SARS-CoV-2. By blocking this binding, IGM 6268 neutralizes the infectivity of the virus. ;
