Study Description

Brief Summary

This clinical trial is studying non-small cell lung cancer (NSCLC). Participants in this study must have cancer that has spread through their body or can't be removed with surgery. Participants in this study must have been treated with no more than a platinum-based chemotherapy and an anti-PD-(L)1 drug. Participants with tumors that have certain treatable genomic alterations must have had no more than 2 drugs for that genomic alteration, in addition to platinum-based chemotherapy.

This clinical trial uses an experimental drug called SGN-B6A, which is a type of antibody drug conjugate or ADC. ADCs are designed to stick to cancer cells and kill them. This clinical trial also uses a drug called docetaxel. Docetaxel is an anticancer drug that has been approved to treat non-small cell lung cancer. It is usually given to patients who previously received another anticancer treatment. In this study, one group of participants will get SGN-B6A on Days 1 and 8 during each 21-day-cycle. A second group of participants will get docetaxel on Day 1 during each 21-day cycle.

This study is being done to see if SGN-B6A works better than docetaxel to treat participants with NSCLC. This study will also test what side effects happen when participants take these drugs. A side effect is anything a drug does to the body besides treating the disease.
