Summary

This is a phase I, open-label, non-randomized, multicenter, dose-escalation trial designed to evaluate the safety, tolerability, and preliminary anti-tumor activity of autologous p95HER2.CAR-TECH2Me T cells in patients with selected advanced HER2-positive (3+) cancers, including locally advanced, recurrent, or metastatic breast, gastric, endometrial, and other selected solid tumors. The study will also assess pharmacokinetics, pharmacodynamics, and immunogenicity of p95HER2.CAR-TECH2Me following intravenous administration.

Treatment consists of non-myeloablative lymphodepletion chemotherapy with cyclophosphamide and fludarabine administered on Days -4 to -2, followed by a single infusion of p95HER2.CAR-TECH2Me cells on Day 0. The investigational product is a live cell suspension of autologous CAR-T lymphocytes derived from the patient's peripheral blood. Premedication will be administered before cell infusion according to protocol requirements.

The primary objective of the study is to evaluate the safety and tolerability of p95HER2.CAR-TECH2Me and to identify the maximum tolerated dose (MTD) and recommended Phase II dose (RP2D). Primary endpoints include the nature and frequency of adverse events, serious adverse events, clinically relevant changes in laboratory parameters, electrocardiograms, vital signs, physical examination findings, and ECOG performance status, as well as the incidence and nature of dose-limiting toxicities. Adverse events will be graded according to NCI CTCAE v5.0, with cytokine release syndrome and neurotoxicity graded according to established consensus criteria.

Secondary objectives include evaluation of preliminary anti-tumor activity and survival outcomes. Secondary endpoints include objective response rate, duration of response, progression-free survival according to RECIST v1.1 as assessed by the investigator, and overall survival.

Approximately 15 patients are planned for enrollment over an estimated 36 to 48 months. The total study duration is expected to be approximately 60 months from the time the first subject signs the pre-screening informed consent form until the last subject completes the final study-related follow-up contact.

p95HER2.CAR-TECH2Me

The treatment includes NMA-LD chemotherapy (cyclophosphamide 500 mg/m²/day + fludarabine 30mg/m2/day for three days) and p95HER2.CAR-TECH2Me cell infusion (1 day). The p95HER2.CAR-TECH2Me product is a cellular investigational product comprising a live cell suspension of autologous CAR-T lymphocytes derived from the patient's peripheral blood.
