Japan Approves Sarclisa SC for Multiple Myeloma, Cutting Infusion Reactions by 94%
June 19, 2026
Approval is supported by IRAKLIA phase 3 data showing non-inferiority of SC to IV in efficacy and pharmacokinetics, with a favorable safety profile.
In IRAKLIA, most common grade 3+ non-hematologic AEs were pneumonia and COVID-19, while neutropenia, thrombocytopenia, and anemia were the leading hematologic events; infusion reactions were notably reduced with SC.
This marks the second global approval for the SC formulation after the EU, with CirCLIQ on-body injector submission in Japan still under review.

IRAKLIA is a randomized, open-label phase 3 trial (NCT05405166) assessing primary outcomes of overall response rate and trough concentration at steady state.
SC administration markedly reduces infusion reactions (about 1.5% vs 25% IV) with minimal local injection-site events (0.4%, mostly grade 1).
Attachments include the Sarclisa press release and links to its clinical trials.
Enable Injections is developing the enFuse On-Body Delivery System to automate SC Sarclisa delivery, aiming to lessen treatment burden and improve convenience.
