Sipavibart: First Approval
摘要
Sipavibart (KAVIGALE®), a recombinant human immunoglobulin (Ig)G1-based antibody, is being developed by AstraZeneca for the pre-exposure prophylaxis of COVID-19 in immunocompromised individuals. Sipavibart was approved in December 2024 in Japan to prevent the onset of infection caused by SARS-CoV-2 in adults and adolescents aged ≥ 12 years weighing ≥ 40 kg where vaccination against infection caused by SARS-CoV-2 is not recommended or may not achieve a sufficient immune response. Sipavibart was also approved in the EU for the pre-exposure prophylaxis of COVID-19 in adults and adolescents aged ≥ 12 years weighing ≥ 40 kg who are immunocompromised due to a medical condition or receipt of immunosuppressive treatments in January 2025 and in Canada in March 2025. This article summarizes the milestones in the development of sipavibart leading to this first approval for the pre-exposure prophylaxis of COVID-19 in immunocompromised adults and adolescents.
