Phase I Study of Decitabine in Combination with Vorinostat in Patients with Advanced Solid Tumors and Non-Hodgkin's Lymphomas
Bibliographic record
Abstract
PURPOSE: This phase I study evaluated the safety, tolerability, pharmacokinetics and preliminary efficacy of the combination of decitabine with vorinostat. PATIENTS AND METHODS: Patients with advanced solid tumors or non-Hodgkin's lymphomas were eligible. Sequential and concurrent schedules were studied. RESULTS: Forty-three patients were studied in 9 different dose levels (6 sequential and 3 concurrent). The maximum tolerated dose (MTD) on the sequential schedule was decitabine 10 mg/m(2)/day on days 1-5 and vorinostat 200 mg three times a day on days 6-12. The MTD on the concurrent schedule was decitabine 10 mg/m(2)/day on days 1-5 with vorinostat 200 mg twice a day on days 3-9. However, the sequential schedule of decitabine 10 mg/m(2)/day on days 1-5 and vorinostat 200 mg twice a day on days 6-12 was more deliverable than both MTDs with fewer delays on repeated dosing and it represents the recommended phase II (RP2D) dose of this combination. Dose-limiting toxicities during the first cycle consisted of myelosuppression, constitutional and gastrointestinal symptoms and occurred in 12/42 (29%) patients evaluable for toxicity. The most common ≥ grade 3 adverse events were neutropenia (49% of patients), thrombocytopenia (16%), fatigue (16%), lymphopenia (14%), and febrile neutropenia (7%). Disease stabilization for ≥ 4 cycles was observed in 11/38 (29%) evaluable patients. CONCLUSION: The combination of decitabine with vorinostat is tolerable on both concurrent schedules in previously treated patients with advanced solid tumors or non-Hodgkin's lymphomas. The sequential schedule was easier to deliver. The combination showed activity with prolonged disease stabilization in different tumor types.

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.
