About FDA Orphan-Drug Designation:
Orphan-Drug Designation is granted to a drug or biological product intended to treat a rare disease in the United States. A number of incentives are provided for an orphan-drug such as 7-year marketing exclusivity, tax credits for clinical development costs, exemption/waiver of application (filing) fees and assistance from the FDA Office of Orphan Products Development (OOPD) during the development process.
About Tenalisib (RP6530):
Tenalisib (RP6530) is a highly selective and orally active dual PI3K delta/gamma inhibitor with efficient translation of activity through enzyme, cell, and whole blood-based studies. Besides inhibiting growth of immortalized cancerous cell lines and primary patient leukemic/lymphoma cells, RP6530 plays a significant role in modulation of tumor microenvironment at clinically achievable concentrations. In preclinical studies, RP6530 reprograms macrophages from an immunosuppressive M2-like phenotype (pro-tumor) to an inflammatory M1-like state (anti-tumor), which can potentially enhance the activity of checkpoint inhibitors or overcome resistance to these drugs. Tenalisib obtained US FDA Fast Track Designation for treatment of peripheral T-cell lymphoma (PTCL) in addition to Orphan-Drug Designations for treatment of peripheral and cutaneous T-cell lymphoma (PTCL and CTCL).
