ListOutcomeTime frameDescription
PrimaryObjective Response Rate (ORR) at Week 25 Per Response Evaluation Criteria In Solid Tumors (RECIST) Version 1.1Baseline to Week 25 (Cycle 7, Day 1)
ORR was assessed by blinded independent radiologic review (IRR) using RECIST Version 1.1. ORR was defined as the percentage of participants who achieved either complete response (CR) or partial response (PR). * CR: Disappearance of all target lesions. Any pathological lymph nodes must be \<10 millimeter (mm) in short axis. Non-nodal targets must be absent. * PR: At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.
SecondaryORR at Week 25 Per Tumor Volume Score (TVS)Baseline to Week 25 (Cycle 7, Day 1)
TVS is a semi-quantitative magnetic resonance imaging (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. ORR was the percentage of participants who achieved either CR or PR as assessed by blinded IRR using TVS. * CR: Lesion completely gone * PR: ≥50% decrease in volume score relative to Baseline.
SecondaryChange From Baseline in Active Range of Motion (ROM) at Week 25Baseline to Week 25 (Cycle 7, Day 1)
Presented here is the change from baseline in active ROM to Week 25. Measurement of the affected and contralateral, non-affected joint was assessed by goniometer and measured in degrees. At baseline, the motion with the smallest relative ROM value (worst) was identified, and this motion was used for evaluating the change in relative ROM subsequently. The affected joint measurement was used to derive a relative ROM based on active measurement relative to reference standard value provided by the American Medical Association. Relative ROM is expressed in percent: 100 x (joint ROM measure)/(reference ROM standard).
SecondaryChange From Baseline in the Patient-reported Outcomes Measurement Information System (PROMIS) Physical Function (PF) Score at Week 25Baseline to Week 25 (Cycle 7, Day 1)
All participants were asked 15 questions from the PROMIS-PF item bank. The questions used one of two 5-point verbal rating scales: either 1 = "unable to do", 2 = "with much difficulty", 3 = "with some difficulty", 4 = "with a little difficulty", and 5 = "without any difficulty"; or 1 = "cannot do", 2 = "quite a lot", 3 = "somewhat", 4 = "very little", and 5 = "not at all." Total scores were converted to T-scores that ranged from 0 to 100, with higher scores representing less physical function interference and better health outcomes.
SecondaryChange From Baseline in the Worst Stiffness Numeric Rating Scale (NRS) Score at Week 25Baseline to Week 25 (Cycle 7, Day 1)
The Worst Stiffness NRS is a single question that asks the participant to assess their worst stiffness in the last 24 hours. Participants rate their worst stiffness on a scale of 0 to 10, where 0 is "no stiffness" and 10 is "worst imaginable." Lower scores represented better level of stiffness.
SecondaryChange From Baseline in EuroQoL Visual Analogue Scale (EQ-VAS) at Week 25Baseline to Week 25 (Cycle 7, Day 1)
The EQ-VAS is a standardized tool for measuring overall health. EQ-VAS recorded the participant's self-rated health on a vertical VAS scale ranging from a minimum of 0 (worst imaginable health state) to a maximum of 100 (best imaginable health state). Higher scores indicated better health state.
SecondaryPercentage of Participants With Response at Week 25 Based on Brief Pain Inventory (BPI) Worst Pain NRS Score and Narcotic Analgesic UseBaseline to Week 25 (Cycle 7, Day 1)
Participants reported responses to the BPI Worst Pain NRS. The BPI Worst Pain NRS ranged from 0 to 10, where 0 is "no pain" and 10 is "pain as bad as you can imagine." A responder was defined as a participant who: (i) experienced a decrease of at least 30% in the mean BPI Worst Pain NRS item and (ii) did not experience a 30% or greater increase in narcotic analgesic use.
