What was measured

Best overall response (CR or PR) was assessed using tumor volume score (TVS) in the ITT population. Tumor Volume Score is a semi-quantitative MRI scoring system that describes tumor mass and is based on 10% increments of the estimated volume of the maximally distended synovial cavity or tendon sheath involved. A tumor that is equal in volume to that of a maximally distended synovial cavity or tendon sheath was scored 10; a score of 0 indicated no evidence of tumor.

Analysis population: Best overall response on Tumor Volume Score was assessed in the ITT population, specifically among the Pexidartinib Part 1, Pexidartinib Part 2; Placebo Part 1, Pexidartinib Part 2; and All Pexidartinib Treated participants. Participants who received Placebo Part 1 only or Pexidartinib Part 2 only were not analyzed..

Groups in this outcome

Pexidartinib Part 1 and Part 2

Participants received treatment of Pexidartinib,1000 mg (5 capsules per day) for 2 weeks, then 800 mg (4 capsules per day) for 22 weeks and also received Pexidartinib in Part 2 at their prescribed dose. Pexidartinib: Each capsule contains 200 mg of Pexidartinib for oral administration.

Placebo Part 1, Pexidartinib Part 2

Participants received treatment of matching placebo (5 capsules per day) for 2 weeks, then matching placebo (4 capsules per day) for 22 weeks in Part 1 and also received Pexidartinib in Part 2 at their prescribed dose. Placebo: Placebo capsule matching Pexidartinib capsule for oral administration Pexidartinib: Each capsule contains 200 mg of Pexidartinib for oral administration.

All Pexidartinib Treated

All participants who received Pexidartinib in Part 1 and Part 2 as well as those who only received Pexidartinib in Part 2.
