Arm | Intervention/treatment |
---|---|
Experimental: Breast Cancer
Patients with locally advanced or metastatic breast cancer that has failed or is intolerant to standard of care therapies. Includes, HER2+, HER 2-, TNBC.
|
Biological: TBio-4101
TBio-4101 is an autologous selected and expanded tumor infiltrating lymphocyte (TIL) product generated following ex vivo expansion of tumor reactive TIL population found in tumor harvest. After preparation with non-myeloablative lymphodepletion chemotherapy (cyclophosphamide and fludarabine) followed by TBio-4101 and IL-2.
Other Name: TIL, autologous, tumor-reactive, T-cell product Drug: Pembrolizumab Pembrolizumab will be administered after TIL infusion and continue every 3 weeks for up to 2 years.
Other Name: Keytruda |
Experimental: Colorectal carcinoma
Patients with advanced, metastatic colorectal adenocarcinoma who have failed or are intolerant to at least one line of therapy that included either irinotecan or oxaliplatin.

- Safety and tolerability [ Time Frame: 25 months ]The incidence of treatment-emergent adverse events will be tabulated using NCI CTCAE v5.0
- Proportion of patients with a response (ORR) [ Time Frame: 25 months ]Percentage of all patients and within each cancer indication with a CR or PR as assessed by the independent central radiologist using RECIST 1.1 and iRECIST
- Estimated Disease Control Rate (DCR) [ Time Frame: 25 months ]Portion of patient whose best response is a CR, PR, or stable disease (SD) as assessed by the independent central radiologist using RECIST v1.1 and iRECIST
- Estimated Duration of Response (DoR) [ Time Frame: 25 months ]Duration of response, as measured in weeks, that patients with a CR or PR have no progressed (PD), as assessed by the independent central radiologist using RECIST v1.1 and iRECIST,
