Maximum 50% of patients with partial tear
• Pain in the affected shoulder (at rest or on movement) on at least 3 days out of 7 days in the past week prior to baseline and a score of ≥4 out of 10 on a VAS pain scale
• Positive "Painful Arc Test" on examination and/or nightly pain in the affected shoulder on at least 4 out of 7 days in the past week prior to baseline
• The rotator-cuff tendinopathy must have been refractory to standard treatment, including NSAIDs and physiotherapy

Exclusion Criteria

• Rheumatologic, inflammatory diseases, including but not limited to: PsA, AS and RA 2. Previous shoulder surgery in affected shoulder 3. History of adhesive capsulitis/frozen shoulder or calcification in the tendon (in affected or contralateral shoulder) confirmed by X-Ray, historic X-Rays can be used if performed within 3 months of baseline 4.
