Study Summary

This trial will test the effects of XMT-1660 on advanced solid tumors.

Who is the study for?
This trial is for adults with certain advanced solid tumors like ovarian, breast, endometrial, fallopian tube, or peritoneal cancer. They should be in good physical condition (ECOG 0-1), have at least one measurable tumor lesion and agree to a biopsy if safe. Not eligible if they've had another cancer treatment within 2 years (except some skin cancers or localized treatments), severe diseases that could affect the study's process, major surgery or anticancer therapy too close to the start of this study, untreated brain metastases, or prior specific ADC treatments.Check my eligibility
What is being tested?
The clinical trial is testing XMT-1660's effectiveness on participants with various types of solid tumors. The main focus is to see how well it works against these cancers and what effects it has on patients' bodies.See study design
What are the potential side effects?
While not specified here, side effects from drugs like XMT-1660 typically include reactions at the injection site, fatigue, nausea and vomiting. There may also be risks associated with organ inflammation and potential impacts on blood cell counts leading to increased infection risk.
