Brief Summary

To demonstrate that combination of cabozantinib and atezolizumab is safe and efficacious in patients with recurrent/metastatic esophageal squamous cell carcinoma.

Females of childbearing potential are defined as premenopausal females capable of becoming pregnant (ie, females who have had any evidence of menses in the past 12 months, with the exception of those who had prior hysterectomy). However, women who have been amenorrheic for 12 or more months are still considered to be of childbearing potential if the amenorrhea is possibly due to prior chemotherapy, antiestrogens, low body weight, ovarian suppression or other reasons.
