Study of Intermittent OSI-906 Dosing

Advanced Solid Tumors Clinical Trial

Official title: A Phase I Dose Escalation Study of Intermittent Oral OSI-906 Dosing in Patients With Advanced Solid Tumors

Status Completed

Clinical Trial Summary

Multicenter, open-label, phase 1, cohort dose escalation study to determine the maximum tolerated dose (MTD) of 3 intermittent OSI-906 dosing schedules.

Clinical Trial Description

Multicenter, open-label, phase 1, cohort dose escalation.

The study will open with Dosing Schedule 1 (S1) (OSI-906 Once Daily (QD) Days 1-3 every 14 days). Dosing Schedule 2 (S2) (OSI-906 QD Days 1-5 every 14 days) will be initiated following observation of clinically significant related toxicity ≥ grade 2 in S1 or after a review of preliminary safety and pharmacokinetic data from ≥ 6 dose levels in S1 indicate that toxicity is acceptable and potential improvement in exposure may be achieved by an increased number of dosing days. Dosing Schedule 3 (S3) (OSI-906 QD Days 1-7 every 14 days) will occur upon observation of clinically significant related toxicity ≥ grade 2 in S2 or after ≥ 1 dose level in S2 has been examined.

A 3-patient bridging dose cohort will be opened in S1 to qualitatively compare the 25 mg capsule with 100 mg capsule dosage strengths in order to confirm that no gross differences in safety or exposure exist between the formulations. In order to characterize the tablet, a 6-patient dose cohort will be opened to qualitatively examine the pharmacokinetics of this dosage form.

Once the MTD has been determined for S1 and once the safety and pharmacokinetic data from the tablet cohort have been reviewed, a Fed-Fasted Expansion Cohort will be opened. ;
