Though naloxone, a short-acting medication, remains the primary treatment option for temporarily reversing opioid overdose effects, alternative countermeasures are needed. Monoclonal antibodies present a versatile therapeutic opportunity that can be tailored to synthetic opioids and help prevent post-treatment renarcotization. The ultrapotent analog carfentanil is especially concerning due to its unique pharmacological properties. With this in mind, we generated a fully human antibody through a drug-specific B cell sorting strategy with a combination of carfentanil and fentanyl probes. The resulting pan-specific antibody was further optimized through scFv phage display, producing C10-S66K. This monoclonal antibody displays high affinity to carfentanil, fentanyl, and other analogs and reversed carfentanil-induced respiratory depression. Additionally, X-ray crystal structures with carfentanil and fentanyl bound provided structural insight into key drug:antibody interactions.
