NW-301 TCR-T in Patients With Advanced Solid Tumor

An open label, two cohorts, multiple dose exploratory clinical study to independently evaluate the safety, efficacy, and pharmacokinetics of autologous anti-KRAS G12V/G12D mutation T-cell Receptor T cell in advanced solid tumor.

This study is an open, two cohorts single infusion, dose escalation/dose regimen finding study to independently assess the safety and pharmacokinetics of KRAS G12V/G12D mutation TCR-T cell therapies, and to obtain the preliminary efficacy results in subjects who have been diagnosed with advanced solid tumor with KRAS G12V/G12D mutation and failed to standard systemic treatment.

Eligibility Criteria:
Inclusion Criteria:

1. Aged 18 to 75 years, male or female;
2. Subjects with pathologically confirmed Pancreatic Cancer and Colorectal Cancer and have been failed to stand of care systemic treatment or have been untolerated to stand of care systemic treatment;
3. HLA-A\*11:01 positive
4. Tumor tissue samples. sample was positive for KRAS G12V or G12D mutation;
5. Estimated life expectancy \> 12 weeks;
6. According to the RECIST 1.1, there is at least one measurable tumor lesion；
7. ECOG physical status score 0 \~ 1;
8. Sufficient venous access for mononuclear cell collection (abbreviation: apheresis)
9. Subjects should have adequate organ functions before screening and pre-treatment (at baseline).
10. Female subjects of childbearing age must undergo a serum pregnancy test at screening and prior to preconditioning and the results must be negative, and are willing to use a very effective and reliable method of contraception within 1 year after the last study treatment. The methods that can be used are: bilateral tubal ligation / bilateral salpingectomy or bilateral tubal occlusion; or approved oral, injection or hormone-imparting contraceptive methods; or barrier contraceptive method: containing spermicidal foam / Gel/film/cream/suppository condom or occlusive cap (diaphragm or cervix/cap);
11. Men who have actively sexual intercourse with women with child-bearing potential, must agree to use barrier-based contraception if they have no vasectomy, for example, a condom containing a spermicidal foam/gel/film/paste/suppository, or use a contraceptive method for their spouse (see article 9 of the inclusion criteria). Moreover, all men are absolutely forbidden to donate sperm within 1 year after receiving the last study treatment infusion； Subject participates in this clinical trial and sign Informed Consent Form voluntarily.
