Phase 2/3 Study of Masitinib in Combination With Gemcitabine Versus Gemcitabine Alone in Advanced/Metastatic Epithelial Ovarian Cancer Patients in Second Line Being Refractory to First Line Platinum Treatment or in Third Line


Brief Summary
The objective is to evaluate the efficacy and safety of masitinib in combination with gemcitabine in refractory ovarian cancer patients.

Detailed Description
Masitinib is a selective tyrosine kinase inhibitor that is thought to promote survival via modulation of immunostimulation-mediated anticancer effects and modulation of the tumor microenvironment. The objective of this study is to evaluate the efficacy and safety of masitinib in combination with gemcitabine as compared with single agent gemcitabine in advanced or metastatic epithelial ovarian cancer patients who are refractory to platinum treatment. This is an open-label, randomized, active-controlled, phase 2/3 study. The study's primary efficacy measure will be overall survival. Masitinib will be prescribed until disease progression (or treatment switch to next line of treatment), death, limiting toxicity or patient consent withdrawal. The study design is a two-stage adaptive design, meaning that it includes a prospectively planned opportunity for modification of one or more specified aspects of the study (for example patient enrollment).


Phase 2 - takes the treatment one step further, assessing the activity of a particular therapy in a disease, often building upon leads from the Phase I trial. While patients are generally required to be previously untreated, participation in a Phase II trial doesn't usually preclude the patient from getting the standard treatment after they've received the investigational agent. At best they are allowed to get a new drug they wouldn't be able to get otherwise that may turn out to be better for their disease.

Inclusion and Exclusion Criteria

  • Female patient, with histologically or cytologically confirmed advanced / metastatic epithelial ovarian cancer (including primary peritoneal and primary fallopian tube cancer), which is either: - First line platinum-refractory ovarian cancer (progression during first-line platinum-based chemotherapy) - First line platinum-resistant ovarian cancer (relapsing within 6 months after the end of first-line chemotherapy); - Candidate to third line of treatment (refractory, resistant, or sensitive to 2nd line platinum-based therapy or patients who progressed after other type of chemotherapy in 2nd line).
  • Patient with adequate organ function per laboratory tests evaluations Main

  • Patient intolerant to gemcitabine
  • Patient who has not recovered from any significant treatment toxicities prior to baseline (≥Grade 2)
  • Pregnant or nursing female patient
