Phase I/II Trial of PTK787 and Pemetrexed With or Without Cisplatin for Lung Cancer

A Two-Cohort Phase I/II Trial of PTK787 and Pemetrexed With or Without Cisplatin in Patients With Advanced Non-Small Cell Lung Cancers and Malignant Pleural Mesotheliomas

Suspended due to data issues revealed at DSMB meeting. Planned amendment but was never submitted. Study was then closed.

This is an open-label, two-arm, multicenter Phase IA/II dose-escalation study of PTK787 in combination with Pemetrexed alone (Cohort 1) or Pemetrexed and Cisplatin (Cohort 2). This study is designed to determine the maximum tolerated dose (MTD) and dose limiting toxicity (DLT) of PTK787 when administered in combination with Pemetrexed or Pemetrexed and Cisplatin, and to characterize the safety, tolerability, biologic activity, and PK profile of PTK787 in adult patients with advanced non-small cell lung cancers and mesotheliomas.

In cohort 1, PTK787 will be administered orally every 12 hours on days 2-42 of a 42-day cycle. In addition, Pemetrexed will be administered on days 1 and 22. In cohort 2, PTK787 will be administered orally every 12 hours on days 2-42 of a 42 day cycle. In addition, Pemetrexed will be administered on days 1 and 22. Thirty minutes after Pemetrexed administration, Cisplatin will be infused on days 1 and 22. In the current study, initially patients will be treated on Cohort 1 (Pemetrexed + PTK787). Once an MTD determination is made on this cohort (or PTK787 has been escalated to the maximum dose of 750 mg Q12h enrollment will begin on Cohort 2. At the MTD dose, both cohorts will be expanded to a minimum of 20 patients to determine additional safety of the combinations.

To determine the Maximum tolerated dose (MTD) and Dose Limiting toxicities (DLTs) of a combination of Pemetrexed and PTK787/ZK222584 (Cohort 1) and a combination of Pemetrexed with Cisplatin and PTK787/ZK222584 (Cohort 2) in patients

To determine the preliminary evidence of safety of the above combinations in patients with non-small cell lung cancers and/or mesotheliomas (in the expansion cohorts)

To determine the effect of therapy with the combination on plasma levels of VEGF A, B, C and D and on plasma levels of soluble VEGF-R2.

To determine the relationship between PTK787/ZK 222584 and Pemetrexed pharmacokinetics and plasma levels of VEGF A, B, C, D, soluble VEGF-R2, and exploratory chemotherapeutic response biomarkers.

To determine the baseline expression of VEGF-R2 by immunohistochemistry in patients where paraffin blocks/slides are available.
