Neoadjuvant leukocyte interleukin injection immunotherapy improves overall survival in low-risk locally advanced head and neck squamous cell carcinoma –the IT-MATTERS study
Bibliographic record
Abstract
The randomized controlled pivotal phase 3 study evaluated efficacy and safety of neoadjuvant complex biologic, Leukocyte Interleukin Injection (LI), administered for 3 consecutive weeks pre-surgery, in treatment naïve resectable locally advanced primary squamous cell carcinoma of oral cavity and soft palate. Randomization 3:1:3 to LI+/-CIZ (cyclophosphamide, indomethacin, and zinc)+SOC, or SOC (standard of care) alone. LI-treated patients received 400 IU (as interleukin-2 equivalent; 200 IU peritumorally, 200 IU perilymphatically) sequentially, daily 5 days/week for 3 weeks before surgery. All subjects were to receive SOC. Post-surgery, patients with low risk for recurrence were to receive radiotherapy, while those with high risk received concurrent chemoradiotherapy. Median follow-up was 56 months. There were 923 ITT (Intent-to-Treat) subjects (380 ITT low-risk and 467 ITT high-risk). Pre-surgery objective early response (45 objective early responders; 5 complete responses [CRs], 40 partial responses [PRs], confirmed by pathology at surgery. LI (+/- CIZ) had 8.5% objective early responders (45/529 ITT) and 16% objective early responders (34/212 ITT low-risk) vs. no reported SOC objective early responders (0/394 ITT). Objective early responders significantly lowered death rate to 22.2% (ITT LI-treated), 12.5% (ITT low-risk LI + CIZ + SOC), while the ITT low-risk SOC death rate was 48.7%. Thus, objective early response impacted overall survival (OS); proportional hazard ratios were 0.348 (95% CI: 0.152-0.801) for ITT low-risk LI-treated, 0.246 (95% CI: 0.077-0.787) for ITT low-risk LI + CIZ + SOC. ITT low-risk LI + CIZ + SOC demonstrated significant OS advantage vs. ITT low-risk SOC (unstratified log-rank p = 0.048; Cox hazard ratio = 0.68; 95% CI: 0.48-0.95, Wald p = 0.024 [controlling for tumor stage, tumor location, and geographic region]). Absolute OS advantage increased over time for ITT low-risk (LI + CIZ + SOC)-treated vs. ITT low-risk SOC: reaching 14.1% (62.7% vs. 48.6%) at 60 months, with 46.5 months median OS advantage (101.7 months vs. 55.2 months), respectively. Quality of life benefit for complete responders sustained for >3 years post LI treatment. Percent treatment-emergent adverse events were comparable among all treated groups. No excess safety issues were reported for LI over SOC alone post-surgery. NCT01265849, EUDRA:2010-019952-35.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
