This is a Phase I, open-label dose finding study to assess the safety, manufacturing feasibility, and preliminary efficacy of TCR1188-ABC cells in patients with KRAS-mutated cancers. Initially, patients with KRAS G12V mutation positive metastatic pancreatic adenocarcinoma, cholangiocarcinoma, colorectal cancer, or non-small cell lung cancer (NSCLC) will be targeted for participation. Up to 4 total dose levels will be evaluated using a 3+3 dose escalation design.

Number of Subjects with treatment related adverse events using NCI Common Terminology Criteria for Adverse Events (CTCAE) V6.0
Type, frequency, severity, and attribution of adverse events
Time frame: Up to 15 years following TCR1188-ABC cell administration
Occurrence of dose-limiting toxicities (DLTs)
Type, frequency, severity, and attribution of dose limiting adverse events as defined by the protocol
Time frame: Up to 28 days following TCR1188-ABC cell administration
Identification of the maximum tolerated dose (MTD)
The highest dose at which 0 or 1 DLT occurs in 6 DLT-evaluable subjects will be declared the MTD.
Time frame: 28 days post-TCR1188-ABC cell infusion
Occurrence of product release failures
Calculated based on the proportion of subjects with TCR1188-ABC cell products that fail to meet the product release criteria, out of the number of eligible subjects in whom manufacturing was attempted, will be calculated.
Time frame: 3 months
Proportion of TCR1188-ABC cells that fail to meet the protocol-defined dose
Proportion of subjects with TCR1188-ABC cell products that fail to meet the assigned dose, out of the number of eligible subjects in whom manufacturing was attempted.
Time frame: 3 months
Overall Response Rate (ORR)
Proportion of subjects with CR or PR as the best overall response as assessed by RECIST 1.1 from the first response assessment post-infusion until the end of the primary follow-up.
Time frame: Up to 12 months following TCR1188-ABC cells administration

Duration of Response (DOR)
Duration of time from the date the response criteria of CR or PR is first met, to the date of confirmed disease progression, or the date of the last adequate disease assessment performed before the occurrence of another censoring event.
Time frame: Up to 15 years following TCR1188-ABC cell administration
Progression-Free Survival (PFS)
Duration of time from the TCR1188-ABC cell infusion to the date of confirmed disease progression or death due to any cause, or the date of the last adequate disease assessment performed before the occurrence of another censoring event.
Time frame: Up to 15 years following TCR1188-ABC cell administration
Overall Survival (OS)
Time from the first TCR1188-ABC cell infusion to death due to any cause; or censored at the date of last contact.
Time frame: Up to 15 years after last TCR1188-ABC cells administration
