Phase II study of oral ENMD-2076 administered to patients with ovarian clear cell carcinoma: A trial of the Princess Margaret Phase II Consortium.
Bibliographic record
Abstract
TPS5620 Background: Ovarian clear cell carcinoma (OCCC) represents nearly 15% of all epithelial ovarian carcinomas (EOC). This histology is associated with resistance to chemotherapy and a worse prognosis. VEGF has been found to be strongly expressed in OCCC. Somatic mutations in the ARID1A (the AT-rich interactive domain 1A gene that encodes BAF250a, a key component of the SWI/SNF chromatin remodeling complex) has also been demonstrated in 46-57% of OCCCs. Alteration of this chromatin remodeling complex may result in upregulation and overexpression of Aurora A. ENMD-2076 is a multi-target kinase inhibitor, which has selective activity against Aurora A and multiple antiangiogenesis and lymphangiogenesis targets. In a Phase II study in platinum-resistant EOC, 58% of the patients treated with single agent ENMD-2076 showed partial response or stable disease, the PFS at 6 month was 22% with a median time to progression of 3.6 months. Two out of 3 patients with OCCC who were enrolled had a longer PFS than the median. Methods: This is a multi-center, Phase II study, in patients with recurrent OCCC to assess response rate and progression free survival rate, as primary endpoints, and duration of overall response, as a secondary endpoint, of single agent ENMD-2076 275 mg/day. Exploratory endpoints include association of somatic mutations in PI3KCA, ARID1A and PTEN, and ARID1A and PTEN expression with outcome and response. Patients ECOG ≤2, with histologically documented diagnosis of recurrence OCCC, any number of prior treatment regimens (chemotherapy, biologics or other target therapies except for Aurora A targeted therapies), and measurable disease (RECIST criteria 1.1) are eligible. Based on data from previous studies, a sample size of 36 patients will provide 95% power to detect an improvement in response rate from 10 to 30% and 90% power to detect an increase in 6 month PFS from 20 to 40%. Since September 2013, 6 patien Clinical trial information: NCT01914510.

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.
