Masitinib in Patients With Gastrointestinal Stromal Tumour After Progression With Imatinib

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
ClinicalTrials.gov Identifier: NCT01694277
Recruitment Status : Completed
First Posted : September 27, 2012
Last Update Posted : December 8, 2020

AB Science

Brief Summary:
The objective is to compare the efficacy and safety of masitinib at 12 mg/kg/day to sunitinib at 50 mg/day in the treatment of patients with gastro-intestinal stromal tumor (GIST) after progression with imatinib.

Condition or disease Intervention/treatment Phase
Gastrointestinal Stromal Tumors Drug: Masitinib Drug: Sunitinib Phase 3

Detailed Description:
Masitinib is a selective tyrosine kinase inhibitor with potent activity against wild-type c-Kit, the juxta membrane domain of c-Kit, and PDGFR. Masitinib is also thought to promote survival via modulation of immunostimulation-mediated anticancer effects and modulation of the tumor microenvironment. The objective is to compare the efficacy and safety of masitinib at 12 mg/kg/day with respect to sunitinib at 50 mg/day in the treatment of imatinib-resistant gastro-intestinal stromal tumor (GIST).

Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Prospective, Multicenter, Randomized, Open-label, Active-controlled, Two-parallel Groups, Phase 3 Study to Compare the Efficacy and Safety of Masitinib to Sunitinib in Patients With Gastrointestinal Stromal Tumor After Progression With Imatinib at 400mg as First Line Treatment
Study Start Date : April 2012
Actual Primary Completion Date : December 2020
Actual Study Completion Date : December 2020

Arm Intervention/treatment
Experimental: Masitinib
Participants receive masitinib (12 mg/kg/day), given orally twice daily.
Drug: Masitinib
12 mg/kg/day
Other Name: AB1010

Active Comparator: Sunitinib
Participants receive sunitinib, given at 50 mg/day for 4 consecutive weeks out of 6 weeks, orally
Drug: Sunitinib
50 mg/day
Other Name: Sutent

Primary Outcome Measures :
  1. Overall Survival (OS) [ Time Frame: From day of randomization to death, assessed for a maximum of 60 months ]
    Overall survival is defined as time in months from the randomization date to the date of death due to any cause. If a patient is not known to have died, then OS will be censored at the date of last known date patient alive.

Secondary Outcome Measures :
  1. Survival rate [ Time Frame: Every 12 weeks until study completion, assessed for a maximum of 60 months ]
    Survival rate is defined as the number of patients alive divided by the number of patients in the population of analysis. Assessed at week-8, -16, -24, and every 12 weeks thereafter.

  2. Progression Free Survival (PFS) [ Time Frame: From day of randomization to disease progression or death, assessed for a maximum of 60 months ]
    Progression Free Survival is defined as the time from the randomization date until the date of earliest evidence of disease progression or death, for participants who progressed or died before subsequent cancer therapy. Disease progression will be assessed by the investigator on CT scan according to RECIST 1.1 criteria and/or CHOI criteria.
