Description: GDC-0927, also known as SRN-927, is a next-generation oral SERD which appears to have greater potential than GDC-0810 to be a best-in-class SERD molecule. GDC-0927 targets estrogen receptor alpha (ERα), a receptor expressed in more than 70% of breast cancers, making it a popular target for the disease. GDC-0927 appears well-tolerated to date with PK exposure supporting QD dosing, evidence of robust PD target engagement, and encouragement of anti-tumor activity in heavily pretreated patients with advanced or metastatic ER+ BC, including patients with ESR1 mutations.
