CD70 targeted CAR-T cell therapy for advanced solid tumors

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial evaluates the safety and efficacy of autologous CD70 targeted chimeric antigen receptor modified T (CAR-T) cell therapy in patients with CD70 positive advanced or metastatic solid tumors. It is a single-center, single-arm, prospective, open-label study that includes a dose escalation phase with at least 12 patients receiving three doses of CD70-CAR-T cells, followed by a dose expansion phase enrolling up to 21 additional patients at the recommended phase 2 dose. The trial aims to address the challenges of treating solid tumors by leveraging the unique properties of CD70 as a target for immunotherapy.

4. At least one measurable lesion at baseline per RECIST version 1.1.
5. Fresh solid tumor samples or formalin-fixed paraffin embedded tumor archival samples within 6 months are necessary; Fresh tumor samples are preferred. Subjects are willing to accept tumor rebiopsy in the process of this study.
6. Adequate organ function as defined by the following criteria: ANC≥1.5x10\^9/L; Platelet count ≥75x10\^9/L; Hemoglobin ≥90 g/L;Serum AST and serum ALT, ≤3.0 x ULN (≤5 x ULN for patients with liver cancer or metastases); Total serum bilirubin ≤1.5 x ULN(≤3 x ULN for patients with liver cancer or metastases); Serum creatinine ≤1.5 xULN or creatinine clearance of ≥60 mL/min.
7. Pregnancy tests for women of childbearing age shall be negative; Both men and women agreed to use effective contraception during treatment and during the subsequent 1 year.
8. Ability to understand and sign a written informed consent documen.

Exclusion Criteria:

1. Subjects are being treated with either corticosteroids (\>10 mg daily prednisone equivalent) or other immunosuppressive medications within 14 days of enrollment.

6. Prior organ allograft transplantations or allogeneic hematopoietic stem cell transplantation;
7. Major surgery or trauma occurred within 28 days prior to enrollment, or major side effects have not been recovered.
8. Known brain metastases or active central nervous system (CNS).Subjects with CNS metastases who were treated with radiotherapy for at least 3 months prior to enrollment, have no central nervous symptoms and are off corticosteroids, are eligible for enrollment, but require a brain MRI screening.
9. Previous or concurrent cancer within 5 years prior to treatment start except for curatively treated cervical cancer in situ, non-melanoma skin cancer, superficial bladder tumors;
10. Any serious underlying medical (eg, pulmonary, renal, hepatic,gastrointestinal, or neurological) or psychiatric condition or any issue that would limit compliance with study requirements;
