Phase I Open-Label Study of Continuous Treatment with BIBF 1120, a Triple Angiokinase Inhibitor, and Pemetrexed in Pretreated Non–Small Cell Lung Cancer Patients
Bibliographic record
Abstract
INTRODUCTION: BIBF 1120 (planned brand name Vargatef) is a novel, oral, triple angiokinase inhibitor targeting three receptor classes involved in blood vessel formation. The objectives of this phase I, open-label dose-escalation study were to determine the safety, tolerability, and maximum tolerated dose (MTD) of BIBF 1120 with pemetrexed in patients with recurrent advanced-stage non-small cell lung carcinoma. PATIENTS AND METHODS: Patients harboring a tumor of any non-small cell lung carcinoma histology, previously treated with one first-line platinum-based chemotherapy regimen, received a BIBF 1120 starting dose of 100 mg bid (days 2-21) with pemetrexed 500 mg/m2 (day 1) over a 21-day cycle. Previous pemetrexed treatment was not permitted. BIBF 1120 dose was escalated until the MTD was determined. RESULTS: Twenty-six patients were treated. During treatment cycle (TC) 1, dose-limiting toxicities were experienced by one patient receiving 100 mg bid, one patient receiving 150 mg bid, one patient receiving 200 mg bid, and two patients receiving 250 mg bid BIBF 1120. Two additional dose-limiting toxicities were observed in TC 1 in an expanded patient cohort receiving 200 mg bid. Gastrointestinal disorders (84.6%), general disorders, and administration site conditions (76.9%) were the most frequent drug-related adverse events. One patient had a complete response 44 days after initiating trial medication; 50% had stable disease as the best overall response. No clinically relevant pharmacokinetic interactions between BIBF 1120 and pemetrexed were observed. CONCLUSION: The MTD of BIBF 1120 in combination with standard-dose pemetrexed was 200 mg bid. Continuous daily treatment with BIBF 1120 in this combination was tolerable, with promising signs of efficacy.

How this classification was reachedexpand
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.
