Inclusion Criteria:

Signed informed consent must be obtained prior to participation in the study.
Males and non-pregnant, non-nursing females between 18 and 65 years of age

Symptoms present for at least 6 weeks but not more than 6 months at Baseline

Moderate to severe rotator cuff tendinopathy demonstrated by all of the following criteria:

WORC score ≤ 40 at Baseline
NRS pain score ≥ 5 at Baseline and at least 3 days of the past 7 days prior to Baseline
Nocturnal pain at least 4 out of past 7 days in the week prior to Baseline
Failure to at least 8 weeks of conventional therapy prior to Baseline: inadequate response to NSAIDs and/or paracetamol and physiotherapy; or intolerance to NSAIDs and/or paracetamol

Exclusion Criteria:

Greater than 50% partial thickness tear as established by MRI or ultrasound during assessment in Run-in phase
Patients who are expected to require glucocorticoid treatment throughout the trial duration at Baseline (e.g., systemic, intramuscular, local injections in shoulder)
Previous surgery, or plans for surgery, during the study period, in the affected shoulder
Rheumatologic and chronic inflammatory diseases, including but not limited to inflammatory bowel disease, polymyalgia rheumatica (PMR), PsA, axSpA and rheumatoid arthritis (RA), fibromyalgia or severe pain disorder unrelated to the target shoulder
Rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) antibodies positive at Screening
History of adhesive capsulitis/frozen shoulder or calcification in the tendon (in affected or contralateral shoulder) confirmed clinically or by medical imaging
Symptomatic osteoarthritis of the shoulder (glenohumeral, acromioclavicular) in affected or contralateral shoulder confirmed by medical imaging
Patients with traumatic rupture that would be considered eligible for surgery for repair of cuff tear.
Neurological conditions including but not limited to cervical radiculopathy, which in the opinion of the investigator may explain the patient's symptoms
Any intra-articular/subacromial glucocorticoid treatment within 12 weeks prior to Baseline or more than 2 injections for the current tendinopathy.
Any oral, intramuscular or i.v. glucocorticoid treatment 12 weeks prior to Baseline or during the current tendinopathy, whichever takes longer
Previous platelet rich plasma (PRP) injections or fluoroquinolone/quinolone antibiotics within 12 weeks prior to Baseline or during the current tendinopathy, whichever takes longer
Neuromuscular or primary/secondary muscular deficiency which limits the ability to perform functional measurement (e.g., shoulder strength test)
Previous hyaluronic injections within 12 weeks prior to Baseline or during the current tendinopathy, whichever takes longer
