Bibliographic record
Abstract
TPS3098 Background: MAGE-A10 is a cancer/testis antigen that has been identified in 42, 26 and 17% of urothelial, melanoma and head and neck tumors, respectively. This study will evaluate the safety and antitumor activity of genetically engineered affinity enhanced autologous MAGE-A10c796T cells directed towards a MAGE-A10 peptide expressed on tumors in the context of HLA *02:01 and/or *02:06. Methods: This first-in-human T cell dose escalation study utilizes a modified 3+3 design to evaluate safety, including dose limiting toxicities (DLT). Secondary objectives include anti-tumor activity (overall response, duration of response, time to response, PFS, OS) and translational research assessments. Patients are screened under a separate protocol (NCT02636855). Those who are HLA*02:01 and/or *02:06 positive and have inoperable or metastatic (advanced) urothelial cancer, melanoma, or squamous cell head and neck tumors with MAGE-A10 expression and meet all other entry criteria are eligible for treatment. Patients must have received standard of care therapies and have progressive disease. Following apheresis, the T cells are isolated and expanded with CD3/CD28 beads, transduced with a lentiviral vector containing the MAGE-A10c796 TCR, and infused into the subject (Day 1) after receiving lymphodepleting chemotherapy (fludarabine 30 mg/m2/day and cyclophosphamide 600 mg/m2/day, on days -7, -6 and -5). The DLT observation period will be during the first 30 days following the infusion of MAGE-A10c796T for each patient in all groups. Up to 10 patients will be enrolled at the target dose. Disease assessments will be conducted at week 6, 12, 18 and 24, and then every 3 months until confirmation of disease progression. On study tumor biopsies and blood samples will be evaluated to compare the pre- and post-T cell infusion immune profile for association with treatment outcome. Clinical trial information: NCT02989064. [Table: see text]

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
