Hiyasta was recently approved by the Japanese Pharmaceuticals and Medical Devices Agency (PMDA) for the treatment of adult T-cell leukemia/lymphoma (ATLL) as monotherapy.

Dr. Mireille Gillings, CEO & Executive Chair of HUYABIO said, “Today’s approval of Hiyasta for ATLL came in just 9 months. Our commercial partnership with Meiji will now bring Hiyasta to patients and provide much needed public health benefit for this devastating, life threatening disease.”

About HBI-8000

HBI-8000 is an epigenetic immunomodulator approved for the treatment of lymphoma and metastatic breast cancer in China. This oral agent targets class I histone deacetylases (HDAC) and suppresses the expression of the viral oncogene HTLV-I bZIP factor, nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kB) and the inflammasome in ATLL cells. Furthermore, HBI-8000 may induce latent viral antigen expression making ATLL cells more sensitive to immune cytotoxicity targeting.
