Trial Outcomes & Findings for Administering Peripheral Blood Lymphocytes Transduced With a Murine T-Cell Receptor Recognizing the G12D Variant of Mutated RAS in HLA-A*11:01 Patients (NCT NCT03745326)

No participants were enrolled on Arm 2/Phase 2 because the study was closed due to lack of accrual and the study outcomes overlapped with another protocol's eligibility. Participants did not complete Phase 1; therefore Phase 2 did not start.

All participants will be evaluable for toxicity from the time of their first treatment with cyclophosphamide. Toxicity was assessed by the Common Terminology Criteria for Adverse Events (CTCAE v5.0). A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life-threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned. Grade 1 is mild. Grade 2 is moderate. Grade 3 is severe. Grade 4 is life-threatening. Grade 5 is death related to adverse event.

Toxicity was assessed by the Common Terminology Criteria for Adverse Events. A DLT is all grade 3 and greater toxicities related to the cell infusion with exceptions, such as myelosuppression, defined as lymphopenia, neutropenia, decreased hemoglobin and thrombocytopenia due to the non-myeloablative lymphodepleting preparative regimen, expected chemotherapy toxicities, Aldesleukin expected toxicities, immediate hypersensitivity reactions occurring within 2 hours of cell infusion that are reversible to a grade 2 or less within 24 hours of cell administration with standard therapy, Grade 3 fever, Grade 3 metabolic laboratory abnormalities without significant clinical sequela that resolve to grade 2 within 7 days, Grade 3 autoimmune toxicity that resolves to grade 2 or less within 10 days unless immunosuppression is required, and events that are clearly related to the participants disease. Grade 3 is severe. Grade 4 is life-threatening. Grade 5 is death related to adverse event.

Percentage of participants who have a clinical response (PR+CR) to treatment (objective tumor regression). Response was assessed by the Response Evaluation Criteria in Solid Tumors (RECIST) (version 1.1). CR is a disappearance of all target lesions. PR is at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study).
