Summary

A Phase I/II, Open-label study to assess the safety, tolerability, pharmacokinetic, and antitumor efficacy of FWD1802 monotherapy in patients with ER+/HER2- unresectable locally advanced or metastatic breast cancer. This clinical trial aims to explore the role of FWD1802 in the ER+/HER2- advanced breast cancer patient population. The primary objectives are to address the following questions:

Phase I Study:

Determine the Recommended Phase II Dose (RP2D) and/or Maximum Tolerated Dose (MTD) of FWD1802 in patients with ER-positive, HER2-negative locally advanced or metastatic breast cancer.

Phase II Study:

To evaluate the efficacy of FWD1802 at the RP2D in patients with ESR1-mutated ER-positive/HER2-negative locally advanced or metastatic breast cancer, using objective response rate (ORR) as the efficacy endpoint.

FWD1802

Eligible subjects will receive FWD1802 treatment according to their assigned dose cohort. Dose Escalation Phase: This phase is divided into a Single-Agent Lead-in Period (C0) and a Multiple-Dosing Period (C1). During the single-agent lead-in period, subjects will receive one dose on Day 1, followed by a 6-day dosing pause. In the multiple-dosing period, subjects will be administered FWD1802 once daily. Dose Expansion Phase: Subjects will receive FWD1802 once daily. Each 4-week period constitutes one treatment cycle. Treatment will continue for up to 2 years or until one of the following events occurs (whichever comes first): disease progression, intolerable toxicity, withdrawal of informed consent, loss to follow-up, initiation of new anti-cancer therapy, or death. Patients who remain in the study at the end of the 2-year treatment period and continue to derive clinical benefit may, upon agreement between the investigator and the sponsor, have the option to continue treatment.
