Brief Summary:
This is a two-part, open-label phase 1 study to evaluate safety and preliminary efficacy of M-CENK and N-803 for subcutaneous administration, cryopreserved in subjects with locally advanced or metastatic solid tumors. The study consists of two cohorts: cohort 1 includes subjects with newly diagnosed high-risk solid tumors who have not received prior treatment for high-risk tumors; and cohort 2 includes subjects with relapsed/refractory (r/r) solid tumors who have progressive disease after receiving ≥ 2 prior therapies. The two cohorts will be conducted simultaneously.

    Changes in vital signs from Grades 1-4:

    measured in how many breaths per minute
