Researchers want to learn if sacituzumab tirumotecan (MK-2870) alone or with other treatments can treat certain gastrointestinal (GI) cancers. The GI cancers being studied are either advanced (the cancer has spread to other parts of the body), or unresectable (the cancer cannot be removed with surgery). The goals of this study are to learn: * About the safety of sacituzumab tirumotecan alone or with other treatments and if people tolerate it * How many people have the cancer respond (get smaller or go away) to treatment
Phase 1 trials primarily test safety and dosing in a small number of participants (typically 20–100). Results do not yet speak to efficacy. FDA approval is typically many years away from this stage.
Phase 2 trials begin testing efficacy in a larger patient group (100–300). This is often where biotech binary events occur — positive Phase 2 data can significantly advance a company's pipeline narrative, while failures can be terminal for a program.
Currently recruiting: the trial is enrolling patients. A data readout is not expected until after enrollment closes and the follow-up period is complete.
Merck & Co (MRK) is the sponsoring company for this trial. BiotechSign currently grades this company F (35/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
