This study will test the safety of a drug called PF-08046052/SGN-EGFRd2 in participants with advanced solid tumors. It will also study the side effects of this drug. A side effect is anything a drug does to the body besides treating the disease. Participants will have cancer that cannot be removed (unresectable) or has spread through the body (metastatic). This study will have three parts. Parts A and B of the study will find out how much PF-08046052/SGN-EGFRd2 should be given to participants. Part C will use the dose found in parts A and B to find out how safe PF-08046052/SGN-EGFRd2 is and if it works to treat solid tumor cancers.
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.
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.
