This is a prospective, open label, controlled, exploratory clinical investigation aimed to evaluate the clinical benefit and safety of Tropho Tend in the conservative management of painful Rotator Cuff Tendinopathy (RCT).

All subjects will be involved in the clinical investigation for 4 months for a total of 5 visits (T0= basal visit, T1, T2, T3, T4).

The control group will be represented by patients diagnosed with rotator cuff tendinopathy treated with rehabilitation physiotherapy (standard of care).

The therapy group will be represented by patients diagnosed with rotator cuff tendinopathy treated with rehabilitation physiotherapy + TrophoTend perilesional injection (TrophoTend will be added on to current standard of care).

All the screened patients at the baseline visit (T0), after checking the inclusion/exclusion criteria, will be prospectively included in the clinical investigation, in a 1:1 randomization. Patients will be randomly assigned to the "control group" (N=30pts), receiving rehabilitation physiotherapy (standard of care), or to the "therapy group" (N=30 pts), receiving Tropho Tend as a add on therapy to the rehabilitation physiotherapy.

Total duration of Clinical Investigation will be 12 months: 2-4 months for patients screening and enrolment; 1 month of therapy administration (3 perilesional injections 2 weeks apart); 3 months of follow-up; 2-4 months for data analysis and final report/paper elaboration.

At the baseline visit (T0), an ultrasound evaluation (EUS) has to be performed to assess tendon condition. If an EUS evaluation performed within one month from T0 is available, this will be considered acceptable. This first evaluation has to be compared with another EUS performed at the final visit to obtain a qualitative description of the ultrasound appearance of the tendon after the treatment.

Patients' enrolment will take 2-4 months. Tropho Tend will be administrated at T0 (basal visit) at T1 (2 weeks) and at T2 (4 weeks) for a total duration of treatment of 1 month.

Follow-up will be performed at T3 (8 weeks) and T4 (12 weeks= 3 months). End of the clinical investigation will be considered the last visit for the last enrolled patient.

A 40% reduction in mean VAS scores between the "Tropho Tend therapy group" and the "control group" is considered as reflecting meaningful clinical improvement for the patient.

At the final visit, the patient has to rate his/her satisfaction with the treatment using a 5-points Likert scale, where 1=very dissatisfied, 2=dissatisfied, 3=neutral, 4=satisfied, 5=highly satisfied.

Inclusion Criteria

• Male and female patients ≥ 18 years of age, in good general health condition.
• Painful Rotator Cuff Tendinopathy (RCT) since ≥ 6 weeks.
• Pain and impaired functionality on a 0 to 10 cm-centimeter specifically designed Visual Analogue Scale (VAS) ≥ 4 cm at baseline visit.
• Rotator Cuff Tendinopathy (RCT) diagnosis, based on clinical examination.
• Tendon ultrasound (EUS) performed within one month of enrollment.

Exclusion Criteria

• Treatment with any investigational product within 6 months prior to clinical investigation entry.
• Patients with known hypersensitivity to the products (active compound and excipients) or any component or procedure used in the clinical investigation.
• Patients with para-tendinopathy, partial/total rupture, previous tendon surgery.
• Severe intercurrent illness (e.g.: uncontrolled diabetes mellitus, peripheral neuropathy, autoimmune or inflammatory condition, metabolic disorders, severe oncological conditions) that, in the opinion of the investigator, may put the patient at risk when participating in the clinical investigation or affect the patient's ability to take part in the clinical investigation .
