Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Pigmented Villonodular Synovitis (PVNS) Tumor Size	To assess the efficacy of a single i.v. dose of MCS110 in changing the size of PVNS tumors (as compared to baseline) compared to placebo over 4 weeks evaluated by volume of PVNS tumors by 3-dimensional MRI. This analysis includes all data from patients 4 weeks after receiving the first dose of MCS110 (3, 5 or 10 mg/kg) or placebo and assesses the tumor volume changes at week 4 as compared to baseline. As all parts (Part A, B and C) of the study are assessed after a single dose at week 4 the data set is called "ABC4".	Week 4
Primary	Percent Change in Pigmented Villonodular Synovitis (PVNS) Tumor Size	To assess the efficacy of a single i.v. dose of MCS110 in percent change of the PVNS tumor volume at week 4 as compared to baseline and compared to placebo evaluated by volume of PVNS tumors by 3-dimensional MRI. This analysis includes all data from patients who received at least a single dose of MCS110 (3, 5 or 10 mg/kg) or placebo and assesses the tumor volume changes at week 4 as compared to baseline. As all parts (Part A, B and C) of the study are assessed after a single dose at week 4 the data set is called "ABC4".	Week 4
Primary	Change in Pigmented Villonodular Synovitis (PVNS) or Giant Cell Tumor of the Tendon Sheath (GCTTS) Tumor Size	Assessment of maximum efficacy (multiple i.v.monthly doses (2 to 6) of 3, 5 or 10 mg/kg MCS110 or 3 & 10 mg/kg or 5 & 10 mg/kg in changing PVNS tumor volume (as compared to baseline) up to 8 weeks post last dose evaluated by MRI. Analysis included data starting from 1st dose of MCS110 in all treatment groups of Parts B and C. Part B patients who received placebo as 1st dose, measurement prior to receiving first dose of MCS110, was used as baseline and assessment time-points were adjusted accordingly. For Part C, participants starting treatment with low dose of MCS110 of 3 or 5 mg/kg could switch to 10 mg/kg after 3 monthly doses, if MCS110 was well tolerated and tumor volume reduction was = 45%. Analysis includes data from patients who received at least 2 doses. The following five groups were assessed: Subjects receiving only 3 mg/kg, only 5 mg/kg or 10 mg/kg and those who switched after 3 doses of 3 mg/kg to 10 mg/kg [3/10 mg/kg] or after 3 doses of 5 mg/kg to 10 mg/kg [5/10 mg/kg]	Up to 8 weeks post last dose
Primary	Percentage Change in Pigmented Villonodular Synovitis (PVNS) or Giant Cell Tumor of the Tendon Sheath (GCTTS) Tumor Size	To assess the maximum efficacy of multiple monthly i.v. doses (2 to 6) of 3, 5 or 10 mg/kg MCS110 or 3 and 10 mg/kg or 5 and 10 mg/kg by percent change in the PVNS tumor volume (as compared to baseline) up to 8 weeks post last dose evaluated by MRI. Subjects starting treatment with a low dose of MCS110 of 3 or 5 mg/kg could switch to 10 mg/kg after 3 monthly doses, if MCS110 was well tolerated and the tumor volume reduction was = 45%. This analysis includes data from all participants who received at least 2 doses of MCS110 and thus includes only patients from Part B and C of the study, thus the data set is called "Part BC". The following five groups were assessed: Subjects receiving only 3 mg/kg, only 5 mg/kg or 10 mg/kg and those who switched after 3 doses of 3 mg/kg to 10 mg/kg [3/10 mg/kg] or after 3 doses of 5 mg/kg to 10 mg/kg [5/10 mg/kg].	Up to 8 weeks post last dose

Secondary	Change in Serum C-terminal Type 1 Collagen Peptide Concentrations (CTX-I).	Pharmacodynamic characterization of a single dose of MCS110 by measuring C-terminal telopeptide of Type 1 Collagen peptide (CTX-I), a biomarker of bone resorption. Data measured in participants from three arms: participants from Part A, B and C who received a single dose of 10 mg/kg and had assessment at week 4 (Part ABC4); participants from Part A and B who received placebo ; and participants from Part B and C who received multiple monthly doses of MCS110 (10 mg/kg.) Serum CTX-I data were generated in Part A and Part B. In Part C, samples were collected for serum bone CTX-I analysis. The analysis was not performed, as enough information on compound mode of action was obtained using creatine kinase (CK) and monocytes (hematology) data. Only data from 10mg/kg (single and multiple doses) are available.	Baseline, Week 4, Week 24, Week 104
Secondary	Number of Participants With Negative Anti-MCS110 Antibody	To assess the immunogenicity of MCS110 in serum anti-MCS110 antibody concentrations	Baseline, throughout the study up to Day 505

The analysis includes all data from patients 4 weeks after receiving the first dose of MCS110 (3, 5 or 10 mg/kg) or placebo. As all parts (Part A, B and C) of the study are assessed after a single dose at week 4 the data set is called "ABC4".	Week 4
Secondary	Assessment of Change From Baseline in Joint Range of Motion for Knee Extension and Flexion	To assess the clinical response of joint range of motion following multiple dose treatment with MCS110 3, 5, or 10 mg/kg evaluated in participants with knee tumor, which was the majority of participants (75%). The data presented are changes from baseline in degree. Participants, who started treatment with a low dose of MCS110 of 3 or 5 mg/kg could switch to 10 mg/kg after 3 monthly doses, if MCS110 was well tolerated and the tumor volume reduction was = 45%. This analysis includes data from participants with knee tumor who received at least 2 doses of MCS110 and thus includes only patients from Part B and C of the study, thus the data set is called "Part BC". The following five groups were assessed: Subjects receiving only 3 mg/kg, only 5 mg/kg or 10 mg/kg and those who switched after 3 doses of 3 mg/kg to 10 mg/kg [3/10 mg/kg] or after 3 doses of 5 mg/kg to 10 mg/kg [5/10 mg/kg].	Week 24/28, Week 104
Secondary	Change From Baseline in Joint Pain Using a Visual Analog Scale (VAS)	Measurement of the participant's pain with a 100 mm visual analog scale (VAS) following treatment with MCS110 3, 5, or 10 mg/kg evaluated. Data presented are changes from baseline in degree. Participants were asked to place a line perpendicular to the VAS line at the point that represented her/his pain intensity. Using a ruler, the score was determined by measuring the distance (mm) on the 10-cm line between the "no pain" anchor and the participants mark, providing a score from 0-100. Analysis includes data from participants with knee tumor who received at least 2 doses of MCS110 and thus includes only patients from Part B and C of the study, thus the data set is called "Part BC". The following five groups were assessed: Subjects receiving only 3 mg/kg, only 5 mg/kg or 10 mg/kg and those who switched after 3 doses of 3 mg/kg to 10 mg/kg [3/10 mg/kg] or after 3 doses of 5 mg/kg to 10 mg/kg [5/10 mg/kg].

Secondary	Time to Relapse	Time to relapse describes the time frame from baseline when the tumor volume increases again after the treatment with MCS110. To be considered a relapse tumor volume had to increase greater than 50% of the difference between tumor volume at baseline and the lowest tumor volume measured by MRI. In this assessment the Part B and Part C patients were analyzed separately. N/A (not available):Data analysis not performed as sample size was not analyzable as no patient had surgery/relapse.	Up to Week 104
Secondary	Time to Surgery	Time to surgery describes the time frame from baseline to the time point when participants had surgical removement of PVNS tumor. This could be either residual tumor after the tumor volume was reduced or surgery due to relapse. In this assessment the Part B and Part C patients were analyzed separately. Not Available (NA): Data analysis not performed as sample size was not analyzable as no patient had surgery.	Up to Week 104
Secondary	Average of Health-Related Quality of Life Questionnaire Score for mHAQ	The mHAQ assesses 20 activities in 8 categories related to daily life, which are rated on a 4-point Likert scale. The mHAQ is calculated as the average of the single scores with the following scoring: without difficulty =0; with some difficulty =1; with much difficulty =2; unable to do =3. Total score is between 0 - 3.0. Values <0.3 are considered normal. Data presented include only participants, who received multiple doses of MCS110.	up to 104 weeks
Secondary	Number of CD14+ Monocytes and Number of CD14 + Monocytes and CD16+ Monocytes	Blood samples were collected for the evaluation of CD14+ monocytes (using FACS) and CD14+ CD16+ monocytes. Based on preliminary analysis, the quality of the samples did not allow meaningful conclusions to be drawn. Thus, in Part B, the monocyte sample collection was discontinued.	Baseline Up to Week 104
