The Japanese Ministry of Health, Labor and Welfare (MHLW) has granted marketing and manufacturing authorization to French pharma major Sanofi’s (Euronext: SAN) Wayrilz (rilzabrutinib), a novel oral reversible Bruton’s tyrosine kinase inhibitor (BTKi).

The drug is authorized for the treatment of persistent or chronic immune thrombocytopenia (ITP) in patients who do not respond sufficiently to other treatments or in whom tolerability is considered to be problematic. Wayrilz can help address the underlying causes of the disease, through multi-immune modulation, targeting key pathways across the immune system.
