- Registration Number
- NCT02471846
- Lead Sponsor

Group Intervention Description Anti-PD-1/PD-L1 Relapsed Cohort II Atezolizumab Approximately 20 participants whose most recent anti-cancer therapy consisted of single-agent PD-1/PD-L1 blockade and achieved unconfirmed partial response or stable disease will receive GDC-0919, at the MTD or MAD determined during the dose-escalation stage, in combination with atezolizumab. Treatment may continue until unacceptable toxicity or disease progression with an unfavorable risk-benefit ratio. Biopsy Cohort B Atezolizumab Approximately 20 participants with melanoma, HNSCC, gastric, ovarian, Merkel cell, cervical, or endometrial cancer will receive atezolizumab during Cycle 1, followed by combination treatment with GDC-0919 and atezolizumab from Cycle 2 onwards. Serial biopsies of extrahepatic lesions will be performed. Treatment may continue until unacceptable toxicity or disease progression with an unfavorable risk-benefit ratio. Anti-PD-1/PD-L1 Relapsed Cohort I GDC-0919 Approximately 20 participants whose most recent anti-cancer therapy consisted of single-agent programmed death-1 (PD-1)/programmed death-ligand 1 (PD-L1) blockade and achieved best response of confirmed complete or partial response, or stable disease will receive GDC-0919, at the MTD or maximum administered dose (MAD) determined during the dose-escalation stage, in combination with atezolizumab. Treatment may continue until unacceptable toxicity or disease progression with an unfavorable risk-benefit ratio. Anti-PD-1/PD-L1 Relapsed Cohort II GDC-0919 Approximately 20 participants whose most recent anti-cancer therapy consisted of single-agent PD-1/PD-L1 blockade and achieved unconfirmed partial response or stable disease will receive GDC-0919, at the MTD or MAD determined during the dose-escalation stage, in combination with atezolizumab. Treatment may continue until unacceptable toxicity or disease progression with an unfavorable risk-benefit ratio. Biopsy Cohort B GDC-0919 Approximately 20 participants with melanoma, HNSCC, gastric, ovarian, Merkel cell, cervical, or endometrial cancer will receive atezolizumab during Cycle 1, followed by combination treatment with GDC-0919 and atezolizumab from Cycle 2 onwards. Serial biopsies of extrahepatic lesions will be performed. Treatment may continue until unacceptable toxicity or disease progression with an unfavorable risk-benefit ratio. Expansion Cohorts GDC-0919 Approximately 160 participants (40 per diagnosis) with NSCLC, RCC, TNBC, and UBC will receive GDC-0919, at the MTD or MAD determined during the dose-escalation stage, in combination with Atezolizumab. Treatment may continue until unacceptable toxicity or disease progression with an unfavorable risk-benefit ratio. Dose-Escalation Cohort(s) GDC-0919 Approximately 6 to 65 participants will be enrolled and treated at escalating doses of GDC-0919 in combination with fixed-dose atezolizumab. Treatment may continue until unacceptable toxicity or disease progression with an unfavorable risk-benefit ratio. Successive groups of at least 3 participants will be evaluated during a 21-day window for DLTs, which will determine the enrollment and dosing for subsequent cohorts in the dose-escalation stage. The MTD or MAD, whichever is reached first, will be considered for the expansion stage. Biopsy Cohort A GDC-0919 Approximately 20 participants with melanoma, HNSCC, gastric, ovarian, Merkel cell, cervical, or endometrial cancer will receive GDC-0919 during Cycle 1, followed by combination treatment with GDC-0919 and atezolizumab from Cycle 2 onwards. Serial biopsies of extrahepatic lesions will be performed. Treatment may continue until unacceptable toxicity or disease progression with an unfavorable risk-benefit ratio.
