This clinical trial is studying nonsquamous 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 at least 1 drug for that genomic alteration, in addition to platinum-based chemotherapy. This clinical trial uses an experimental drug called sigvotatug vedotin, 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 sigvotatug vedotin on Days 1 and 15 during each 28-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 sigvotatug vedotin 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.
Phase 3 trials are pivotal studies with large patient populations (hundreds to thousands) designed to prove efficacy and safety for FDA submission. A successful Phase 3 readout is typically the last major hurdle before a New Drug Application (NDA) or BLA filing.
Enrollment is complete. The trial is in its follow-up or data collection phase — a readout may occur on or near the primary completion date.
Pfizer Inc (PFE) is the sponsoring company for this trial. BiotechSign currently grades this company F (33/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
