Brief Summary:
This is a multicenter Phase 1b, open-label study to assess safety, tolerability, preliminary efficacy, and pharmacokinetics (PK) of cabozantinib taken in combination with atezolizumab in subjects with multiple tumor types, including advanced urothelial carcinoma (UC) (including bladder, renal pelvis, ureter, urethra), renal cell carcinoma (RCC), castration-resistant prostate cancer (CRPC), non-small-cell lung cancer (NSCLC), triple negative breast cancer (TNBC), ovarian cancer (OC), endometrial cancer (EC), hepatocellular cancer (HCC), gastric cancer/gastroesophageal junction cancer/lower esophageal cancer (GC/GEJC/LEC), colorectal cancer (CRC), head and neck (H&N) cancer, and differentiated thyroid cancer (DTC). The study consists of two stages: in the Dose Escalation Stage, an appropriate recommended cabozantinib dose for the combination with standard dosing regimen of atezolizumab will be established; in the Expansion Stage, tumor-specific cohorts will be enrolled in order to further evaluate the safety and efficacy of the combination treatment in these tumor indications. Three exploratory single-agent cabozantinib (SAC) cohorts may also be enrolled with UC, NSCLC, or CRPC subjects. One exploratory single-agent atezolizumab (SAA) cohort may also be enrolled with CRPC subjects. Subjects enrolled in the SAC cohorts and SAA cohort may receive combination treatment with both cabozantinib and atezolizumab after they experience radiographic progressive disease per the Investigator per RECIST 1.1. Due to the nature of this study design, some tumor cohorts may complete enrollment earlier than others.

- Dose Escalation Stage: to determine the schedule and maximum tolerated dose (MTD) and/or recommended Expansion Stage dose of cabozantinib when taken in combination with a standard dosing regimen of atezolizumab (1200 mg infusion, once every 3 weeks).
- Expansion Stage: to determine the preliminary efficacy (objective response rate [ORR] per RECIST 1.1) and safety of the recommended combination dose of cabozantinib with atezolizumab in eighteen tumor-specific cohorts including subjects with advanced UC, RCC, CRPC, NSCLC, TNBC, OC, EC, HCC, GC/GEJC/LEC, CRC, H&N, and DTC.
- Exploratory SAC Cohorts: Descriptive efficacy, safety, PK, and biomarker analyses of single-agent cabozantinib in UC, NSCLC, and CRPC subjects. Descriptive efficacy and safety analyses of combination therapy after progression on single-agent therapy
- Exploratory SAA Cohort: Descriptive efficacy, safety, PK, and biomarker analyses of single-agent atezolizumab in CRPC subjects. Descriptive efficacy and safety analyses of combination therapy after progression on single-agent therapy

Primary Outcome Measures :
- Dose Escalation: MTD/Recommended Dose [ Time Frame: Up to 6 months ]To determine the maximum tolerated dose (MTD) and/or recommended dose and schedule for the subsequent Expansion Stage of daily oral administration of cabozantinib in subjects with solid tumors when taken in combination with atezolizumab.
- Dose Expansion: ORR [ Time Frame: Up to 31 months ]To evaluate preliminary efficacy by estimating the Objective Response Rate (ORR) as assessed by the Investigator per RECIST 1.1.
Secondary Outcome Measures :
- Incidence and severity of nonserious AEs and SAEs (Safety) [ Time Frame: Up to 41 months ]To assess safety for the combination therapy through the evaluation of incidence and severity of nonserious adverse events (AEs) and serious adverse events (SAEs), including immune-related adverse events (irAEs).
