A Study of SGN-B6A Versus Docetaxel in Previously Treated Non-small Cell Lung Cancer

United States, Argentina, Australia762 participantsStarted 2024-02-21

Plain-language summary

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.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
