| E.3 | Principal inclusion criteria | 
| - Male or non-pregnant, non-lactating female patients 18 to 65 years of age at randomization - Presence of unilateral rotator cuff tendinopathy with:
 a.  Symptoms present ≥6 weeks, but <12 months prior to randomization
 b. Tendinopathy with no more than a 50% tear as established by ultrasound at screening (historic data acceptable if not older than 3 months) and MRI at baseline: Sein MRI tendinopathy scoring system grade I-III; with no tear or partial tear [maximum 50% tendon thickness (Bauer tendon thickness score maximum 2); AP length maximum 10 mm (Bauer tendon length score max 2)]. Maximum 50% of patients with partial tear
 c.  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
 d.  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
 
 Other protocol-defined inclusion criteria may apply.
 |  | 
| E.4 | Principal exclusion criteria | 
| - Rheumatologic, inflammatory diseases, including but not limited to: PsA, AS and RA - Previous shoulder surgery in affected shoulder
 - 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
 - Symptomatic osteoarthritis of the shoulder (gleno-humeral, acromioclavicular) (in affected or contralateral shoulder confirmed by X-Ray, historic X-Rays can be used if performed within 3 months of baseline
 - Neck conditions, including but not limited to cervical spine syndrome, which in the opinion of the investigator, may explain the patient’s symptoms
 - Previous platelet rich plasma injections within the last 12 months prior to randomization
 - Previous treatment with any cell-depleting therapies including but not limited to anti- CD20, investigational agents (e.g. Campath, anti-CD4, anti-CD5, anti-CD3, anti-CD19)
 - Previous exposure to any biologic immunomodulating agents, including but not limited to TNFalpha inhibitors (including, but not limited to adalimumab, infliximab), or biologics targeting IL-17 (including, but not limited to secukinumab, ixekizumab or brodalumab) or the IL-17 receptor within the last 12 months prior to baseline
 - Any intraarticular/subacromial corticosteroid treatment within 8 weeks prior to randomization and more than 3 injections for the current tendinopathy. Oral, intramuscular or i.v. corticosteroid treatment within the last 12 months prior to randomization
 
 Other protocol-defined exclusion criteria may apply.
