Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline in the Adapted American Shoulder and Elbow Surgeons Shoulder Assessment Form (ASES) Composite Score for the Affected Shoulder at Day 95
Time Frame: Baseline, Day 95

Adapted ASES is a self-administered participant reported outcome measure, divided into 2 sections: pain and function. Pain subscale is a single item, 11-point numeric rating scale, ranging from 0 (no pain at all) to 10 (worst pain), calculated as 10 - pain raw score and multiplying by 5, score ranging from 0 (worst pain) to 50 (no pain). Function subscale consists of 10 activities, 4-point ordinal scale about their ability to do the activity with the affected arm, ranging from 0 (unable to do) to 3 (not difficult), calculated by multiplying total score for 10 items by 5 and then dividing it by 3, score range of 0 (no function) to 50 (full function).

Adapted ASES composite score is the sum of the pain subscale score (50% of the composite score) and function subscale score (50% of the composite score), score range of 0 (worst pain) to 100 (least pain). Positive change from Baseline score means an improvement in pain and/or shoulder function.

Change From Baseline in Patient-reported Global Severity of Adhesive Capsulitis Scale
Time Frame: Baseline, Day 22, 43, 64, and 95
The Patient-reported Global Severity of Adhesive Capsulitis is a single item, 11-point numerical rating scale that asks participants to rate the overall severity of their adhesive capsulitis symptoms on a scale from 0 (no severity) to 10 (severe as can be). A decrease from Baseline indicates improvement.

Patient-reported Change in Severity of Adhesive Capsulitis Scale
Time Frame: Days 22, 43, 64 and 95

The Patient-reported Change in Severity of Adhesive Capsulitis is a questionnaire that asks participants if their adhesive capsulitis symptoms are "Better, About the Same, or Worse" since the last time the questionnaire was administered. Participants who reported that their symptoms are better or worse are then asked to rate the change in their symptoms on a 7-point ordinal scale for worse and better severity. An overall severity of worse was rated from 0 (almost the same, hardly worse at all) to -6 (a very great deal worse). An overall severity of better was rated from 0 (almost the same, hardly better at all) to 6 (a very great deal better).

Only participants with a response of 'Worse' or 'Better' were analyzed. Participants with an overall severity response of 'About the same' were excluded from the summary table below. For overall worse severity, a lower score indicated a worse outcome. For overall better severity, a higher score indicated a better outcome.

Days 22, 43, 64 and 95
Number of Responders Assessed With Investigator Assessment of Improvement
Time Frame: Days 64 and 95
Investigator assessment of improvement with treatment in the severity of the participant's treated shoulder using a 7-point Likert scale from very much worse (-3) to very much improved (3). A responder was defined as a response of "very much improved", "much improved" or "minimally improved" in the investigator assessment of improvement with treatment.
Days 64 and 95
Number of Responders Assessed by the Subject Satisfaction With Treatment Assessment
Time Frame: Days 64 and 95
Participants rated their satisfaction with treatment on a 7-point Likert scale from very dissatisfied (-3) to very satisfied (3) at specified times for relief of pain in treated shoulder, relief of stiffness in treated shoulder, relief of pain in treated shoulder compared to better shoulder, and relief of stiffness in treated shoulder compared to better shoulder. A responder was defined as a participant with a response of "very satisfied", "satisfied" or "somewhat satisfied" in the satisfaction with treatment.
Days 64 and 95
Number of Participants Positive for Anti-AUX-I and Anti-AUX-II Antibodies
Time Frame: Day 95
Serum samples were collected and tested for the presence of anti-AUX-I and anti-AUX-II antibodies.
Day 95
Number of Participants Positive for Neutralizing Antibodies
Time Frame: Day 95
Serum samples were collected and tested for the presence of anti-AUX-I and anti-AUX-II antibodies. Only samples positive for anti-AUX-I and anti-AUX-II antibodies were analyzed for neutralizing antibodies.
