A Study of MK-8109 (Vintafolide) Given Alone or With Chemotherapy in Participants With Advanced Cancers (MK-8109-001)

February 9, 2015 updated by: Endocyte

A Phase I Dose Escalation Study Evaluating Vintafolide (MK-8109) Chemotherapy Alone or in Combination in Adult Subjects With Advanced Cancers

This trial will be conducted in three parts. Part A is a dose escalation trial followed by a dose confirmation trial in folate receptor (FR) 100% endometrial cancer participants. The primary hypothesis of this trial is that administration of vintafolide in combination with carboplatin and paclitaxel is safe and tolerable. Part B is a single dose, dose escalation, pharmacokinetic (PK), and QTc interval trial. The primary objectives include determination of the maximum single tolerated dose of vintafolide and to evaluate the effect of this single maximum dose on the QTc interval. Part C is a weekly dose escalation trial of vintafolide followed by a dose confirmation. The primary hypothesis of this part is that weekly vintafolide has acceptable safety and tolerability in participants with advanced cancers.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.
