Description

This prospective, phase I/II trial will initially enroll 9 patients with relapsed, refractory metastatic disease. Two doses of zanzalintinib will be evaluated for toxicity. The patients will receive zanzalintinib orally daily continuously in combination with oral standard of care etoposide daily for 21 days out of 28 day cycles until time of progression or toxicity. The DLT period is 1 cycle of 28 days. We will employ the Bayesian optimal interval (BOIN) design to find the MTD.
