What is Pamiparib?

Description

Pamiparib (BGB-290) is an investigational small molecule inhibitor of PARP1 and PARP2. Pamiparib is being evaluated as a monotherapy in pivotal clinical trials in China in recurrent platinum-sensitive and BRCA1/2 mutated ovarian cancers.

The Uses of Pamiparib

Pamiparib, is a PARP inhibitor, which can be used as an anticancer agent.

in vivo

Oral administration of Pamiparib results in time-dependent and dose-dependent inhibition of PARylation in MDA-MB-436 (BRCA1 mutant) breast cancer xenograft, correlating well with the tumor drug concentrations. It has also demonstrated good combination activity with chemotherapeutics in patient biopsy derived SCLC models. Also Pamiparib has significant brain penetration in C57 mice. The drug exposure in brain vs. that in plasma was close to 20% after oral administration of BGB-290.
