Sanofi SAJapan approved Sanofi's Wayrilz for ITP, expanding market access.

Japan's Ministry of Health, Labour and Welfare has granted marketing authorization to Sanofi's Wayrilz, a novel oral BTK inhibitor, for the treatment of persistent or chronic immune thrombocytopenia in patients with insufficient response or tolerability issues to existing therapies. The approval is based on the LUNA 3 phase 3 study, which enrolled 202 adults and showed that 23% of patients on Wayrilz achieved a durable platelet response at week 25 compared to 0% on placebo, with a faster time to first response of 36 days and a longer duration of response. Patients also reported a 10.6-point improvement in quality of life versus a 2.3-point increase in the placebo arm, though this analysis was descriptive. The most common adverse reactions included diarrhea, nausea, headache, abdominal pain, and COVID-19. Wayrilz is already approved for ITP in the US, EU, UAE, and UK, and is being investigated for other rare diseases including IgG4-related disease, warm autoimmune hemolytic anemia, and sickle cell disease.
