A Phase Ib and Pharmacokinetic Trial of Patupilone Combined with Carboplatin in Patients with Advanced Cancer
Bibliographic record
Abstract
PURPOSE: Patupilone is a microtubule-targeting chemotherapeutic agent with clinical activity in a broad range of taxane-sensitive/resistant tumor types. The present phase Ib study examined the safety/tolerability and pharmacokinetics of patupilone in combination with carboplatin in patients with advanced solid tumors. EXPERIMENTAL DESIGN: Patients with advanced cancer received patupilone via a 5- to 10-min i.v. infusion at doses of 3.6 to 6.0 mg/m(2) q3w, immediately followed by carboplatin area under the curve (AUC) 5 or 6 mg/mL/min. RESULTS: Of the 37 patients enrolled, the majority previously received taxanes (81%) and/or platinum-containing drugs (97.3%). The maximum tolerated dose (MTD) of patupilone with carboplatin AUC 6 was 4.8 mg/m(2); additional patients were enrolled to consolidate experience at this dose. Of the 22 patients who received the MTD, the most common nonhematologic adverse events were fatigue in six (27.3%) and diarrhea, nausea, vomiting, abdominal pain, and neuropathy in one each (4.5%; all grade 3); hematologic toxicities included two patients (9.1%) with grade 3 neutropenia. The pharmacokinetics of patupilone were similar to those in a previous study of patupilone monotherapy. Of the 26 patients with recurrent platinum-sensitive ovarian cancer, tumor response was assessable by response evaluation criteria in solid tumors in 17; 1 patient (6%) achieved a complete response, and 10 (59%) achieved a partial response. CONCLUSIONS: The combination of patupilone 4.8 mg/m(2)/carboplatin AUC 6 was well tolerated and showed antitumor activity similar to established regimens in patients with recurrent platinum-sensitive ovarian cancer. The optimal dose for this regimen is currently being further refined in phase II trials.

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.
