Open label first-in-human study of TH1902 in solid cancer, with 4 sequential parts: Part 1 (dose escalation): patients with recurrent advanced solid tumors (all comers) that have relapsed or are refractory to standard chemotherapy, surgery, radiation therapy, and for which no known effective therapies exist. Part 2 (expansion): selected patient populations with recurrent advanced TNBC, HR+ breast cancer, epithelial ovarian cancer, endometrial cancer, cutaneous melanoma, thyroid cancer, SCLC, prostate cancer and other cancers known to express SORT1 that are refractory to standard therapy. Part 3 (optimization): patients diagnosed with histologically or cytologically confirmed high grade serous ovarian cancer, including high grade peritoneal or fallopian tube cancer, or high grade endometrioid cancer, that is refractory or resistant to standard therapies, should not be considered platinum sensitive, and where current therapy is not considered to be providing benefit. Part 4 (basket expansion): selected cancer type diagnosed with histologically or cytologically confirmed cancers, where TH1902 has been studied and/or showed activity (in Parts 1 to 3), that is refractory or resistant to standard therapies, and where current therapy is not considered to be providing benefit.
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.
Theratechnologies (THTX) is the sponsoring company for this trial. BiotechSign currently grades this company F (10/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
