Leads Biolabs' PD-L1/4-1BB Bispecific Antibody Opamtistomig (LBL-024) Granted Orphan Drug Designation in Japan, Further Expanding Global Regulatory Recognition
Nanjing Leads Biolabs announced that its proprietary PD-L1/4-1BB bispecific antibody, opamtistomig (LBL-024), has been granted Orphan Drug Designation by Japan's MHLW for the treatment of extrapulmonary neuroendocrine carcinoma (EP-NEC). This marks the third such designation for the drug, following earlier ones from the U.S. FDA and the European Commission, expanding its global regulatory recognition into an Asian market.
Why it matters — A watcher of ODD would care because this third orphan drug designation for opamtistomig extends its regulatory recognition into a strategically important Asian market, broadening the drug's global footprint across Japan, the U.S., and Europe.
