This is a randomized, open-label, phase 3 clinical trial to compare the efficacy and safety of N-803 plus tislelizumab and docetaxel (experimental arm) versus docetaxel monotherapy (control arm). Enrolled participants will be randomized 2:1 to treatment in the experimental arm or the control arm. Participant randomization will be stratified by geographical region (North America vs Europe vs ASIA vs Other), NSCLC histology (squamous vs nonsquamous), and actionable genomic alteration (AGA); (epidermal growth factor receptor \[EGFR\]/anaplastic lymphoma kinase \[ALK\] vs OTHER AGA vs No AGA).

This study is being done to answer the following question: can the chance of prostate cancer growing or spreading be lowered by adding a drug to the usual combination of drugs?

This study would like to find out if this approach is better or worse than the usual approach for prostate cancer.

The usual approach for patients who are not in a study is hormone treatment with Androgen Deprivation Therapy (ADT) and Androgen-Receptor Pathway Inhibitor (ARPI).
