About this study
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of participants with adverse events and serious adverse events graded according to CTCAE v5.0
Adverse events and serious adverse events will be collected and summarized by frequency, severity, seriousness, and relationship to study treatment. Events will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0, when applicable. Cytokine release syndrome and neurotoxicity/ICANS will be graded according to the protocol-specified consensus grading criteria.
Measured: Up to 3 months after the infusion
Number of participants with clinically significant abnormalities in clinical safety laboratory tests
Clinical safety laboratory assessments will be performed according to the Schedule of Assessments. Clinically significant new or worsening laboratory abnormalities will be recorded and summarized as adverse events when they meet protocol-defined adverse event criteria. Laboratory values will be assessed using local laboratory reference ranges. The protocol states that abnormal test findings are reported as AEs only if they are symptomatic, require additional testing/intervention or treatment, lead to study drug changes/discontinuation, or are considered AEs by the investigator or sponsor.
Measured: Up to 3 months after the infusion
Number of participants with clinically significant abnormalities in 12-lead electrocardiogram findings
Twelve-lead electrocardiograms will be obtained according to the Schedule of Assessments. Clinically significant new or worsening ECG abnormalities will be summarized as adverse events when applicable.
Measured: Up to 3 months after the infusion
Number of participants with clinically significant abnormalities in vital sign measurements
Vital signs will be assessed as part of the safety evaluations according to the protocol-specified time points. Clinically significant new or worsening abnormalities will be recorded and summarized as adverse events when applicable. The physical examination section specifies that vital signs, height and body weight are included in complete physical examinations.
Measured: Up to 3 months after the infusion
Number of participants with clinically significant abnormalities in physical examination findings
Complete and targeted physical examinations will be performed according to the protocol. New or worsened clinically significant abnormalities identified after baseline will be recorded as adverse events and summarized by frequency.
Measured: Up to 3 months after the infusion
Change from baseline in Eastern Cooperative Oncology Group (ECOG)performance status score
Performance status will be measured using the Eastern Cooperative Oncology Group Performance Status Scale. Scores range from 0 to 5, with higher scores indicating worse functional status.
Measured: Up to 3 months after the infusion
Number of participants with dose-limiting toxicities during the dose-limiting toxicity assessment period
Dose-limiting toxicities will be assessed according to the protocol-defined DLT criteria and summarized by incidence and nature.
Measured: 28 days since the administration.
Secondary outcomes (4)
Objective response rate according to RECIST v1.1 as assessed by the investigator
Objective response rate is defined as the percentage of participants with a confirmed complete response or partial response according to Response Evaluation Criteria in Solid Tumors version 1.1, as assessed by the investigator.
Measured: up to 2 years since the administration
Duration of response according to RECIST v1.1 as assessed by the investigator
Duration of response is defined as the time from the first documented objective response, complete response or partial response, to documented disease progression or death, whichever occurs first, in participants with confirmed complete response or partial response. Participants who are lost to follow-up or are alive and progression-free at the time of analysis will be censored at the last date they are known to be alive and progression-free.
Measured: up to 2 years since the administration
Progression-free survival according to RECIST v1.1 as assessed by the investigator
Progression-free survival is defined as the time from start of study treatment to the date of confirmed disease progression, including radiographic or clinical progression, or death due to any cause, whichever occurs first.
Measured: up to 2 years since the administration
Overall Survival (OS)
Overall survival is defined as the time from start of study treatment to death due to any cause. Participants who are alive at the time of analysis will be censored at the last date they are known to be alive or lost to follow-up.
Measured: up to 2 years since the administration

What does the primary outcome measure?
Number of participants with adverse events and serious adverse events graded according to CTCAE v5.0 (time frame: Up to 3 months after the infusion). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 May 2026.
