About this study

Official title: A Phase I/II, Open-label Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Anti-tumor Efficacy of FWD1802in Patients With ER+/HER2- Unresectable Locally Advanced or Metastatic Breast Cancer

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:

Read more

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.

Read the detailed description

This is a phase I/II, multicenter, open-label, first-in-human study of FWD1802 in patients with locally advanced or metastatic breast cancer that is estrogen receptor (ER)-positive/human epidermal growth factor receptor 2 (HER2)-negative (Phase II: restricted to patients with ESR1-mutated). It consists of three parts: the FWD1802 dose-escalation phase (Phase I Part A), the FWD1802 dose-expansion phase (Phase I Part B), and the dose-expansion study of FWD1802 in patients with ESR1 mutations (Phase II study).

Each study phase includes a screening period (up to 4 weeks), a treatment period (maximum treatment duration of 2 years; continuation beyond 2 years is permitted if the investigator judges the subject is still benefiting, with agreement from both the investigator and sponsor), and a follow-up period. The Phase II study includes a pre-screening period; patients with unknown mutation status may undergo testing that includes ESR1 mutation status prior to the screening period.

Phase I Part A is the FWD1802 dose-escalation study: A dose-escalation trial using a combination of an "accelerated titration" design and a "3+3" design is planned, with a maximum of 27 subjects to be enrolled. The Safety Monitoring Committee (SMC) will evaluate pharmacokinetic (PK), pharmacodynamic (PD), efficacy, and safety data to guide the determination of potentially effective doses for Part B and the Phase II study.

Phase I Part B is the FWD1802 dose-expansion study: Based on safety, PK, PD, and other data obtained from Part A, 2 to 4 dose cohorts will be selected for further exploration of FWD1802's PK profile and the recommended phase 2 dose (RP2D). Each dose cohort will be expanded to include up to 10 subjects (including subjects from the corresponding dose cohort in Part A). The SMC will decide which dose cohorts to expand and the timing of expansion based on information obtained from Part A. Dose expansion may proceed concurrently with the dose-escalation phase, within dose ranges already confirmed as safe by the SMC.

The Phase II study is cohort expansion study targeting the population with ESR1 mutations: Enrolled subjects will have ER-positive, HER2-negative breast cancer with ESR1 mutations. One to two dose levels will be selected for exploration, with each dose level enrolling no more than 30 subjects, for a maximum total enrollment of 60 subjects.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • FWD1802Drug

    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.

Study groups in NCT06064812
Study groupRoleWhat they receive
Phase I Study Part A: Dose Escalation.ExperimentalPart A study will be conducted in subjects diagnosed with ER+/HER2- unresectable locally advanced or metastatic breast cancer. A maximum of 27 subjects will be enrolled. They will be sequentially allocated to 5 planned dose cohorts: 25 mg, 75 mg, 150 mg, 300 mg and 450 mg. Subjects enrolled will be orally administered a single dose of FWD1802 Tablet on C0D1, followed by a 3-day observation period. Starting on C1D1, FWD1802 Tablet will be orally administered continuously QD for 28 consecutive days of each cycle. The DLT observation period is set as 32 days(C0D1-C1D28). The second cycle and subsequent cycles will last for 28 days per cycle. The patients will continue to receive the study treatment until PD, death, unacceptable toxicity, withdrawal of informed consent, or other reasons to discontinue study treatment occurs, whichever comes first.
Receives: Drug: FWD1802
Phase I Study Part B - Dose Expansion.ExperimentalPart B will be conducted based on the dose-escalation results from Part A (comprehensive safety, PK, PD, and other data), selecting 2 to 4 dose cohorts for further exploration of the PK characteristics and RP2D of FWD1802. Each dose cohort will be expanded to include a maximum of 10 subjects (this total includes subjects from the corresponding dose cohort in Part A). The doses selected for Part B must be within the dose levels already explored and confirmed as safe to ensure that all doses in Part B fall within a known safety range. The SMC will decide on the 2 to 4 doses for expansion, which may include doses already confirmed as safe in Part A or new doses within the established safe range. The timing for initiating Part B will be jointly determined by the SMC and the sponsor based on the information already obtained from Part A. Part B may commence concurrently with the dose-escalation phase. The 2 to 4 dose cohorts in Part B may be conducted simultaneously or sequentially.
Receives: Drug: FWD1802
Phase II Study - Dose Expansion in ER+/HER2- Subjects with ESR1 Mutations.ExperimentalThe dose expansion study will be conducted in approximately 60 subjects diagnosed with ER+/HER2- locally advanced or metastatic breast cancer harboring ESR1 mutations, to evaluate the efficacy, safety and PK of FWD1802 at the recommended 1 to 2 dose level(s). The specific number of subjects, dosage(s), and dosing regimen in the dose expansion study will be comprehensively determined by the SMC based on the results from the Phase I, Part A study. Subjects will undergo ctDNA testing before treatment initiation, on Cycle 1 Day 15 (C1D15), on Cycle 2 Day 1 (C2D1), after disease progression, and when deemed necessary based on the subject's therapeutic response, to determine the baseline mutation sites, types, and frequencies of ESR1 and/or other breast cancer-related genes.
Receives: Drug: FWD1802
