Study of Efficacy and Safety of Secukinumab in Participants With Moderate-severe Rotator Cuff Tendinopathy

Study of Efficacy and Safety of Secukinumab in Participants With Moderate-severe Rotator Cuff Tendinopathy

A Randomized, Parallel-group, 24 Week, Double-blind, Placebo-controlled, Multicenter Phase 3 Study to Assess the Efficacy and Safety of Secukinumab Compared to Placebo in Adult Patients With Active Rotator Cuff Tendinopathy

The purpose of the present study is to assess the efficacy of secukinumab 300 mg s.c. (subcutaneous) compared to placebo, each in combination with standard of care, in improving signs, symptoms and physical function in participants with moderate to severe rotator cuff tendinopathy (RCT), using a randomized, double-blind, placebo controlled, parallel group design to minimize bias.

The trial is designed as a randomized, double-blind, placebo-controlled Phase III study over 24 weeks in approximately 234 participants with moderate to severe rotator cuff tendinopathy (RCT), refractory to Standard of Care (Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) course as per local standard practice, if not intolerant or contraindicated, and a course of physiotherapy over a period of 8 weeks). The trial comprises the following periods: - Screening / run-in period A screening period of up to maximum of 56 days will be used to assess participant eligibility. During this time, the participant can demonstrate that they are refractory to Standard of Care. During the 2-week run-in period prior to the Baseline visit, the participant will need to have 2 weeks of stable NSAID intake and standardized physiotherapy. This is important in order to ensure the participants are refractory to SoC and to establish compliancy with the stabilized dosing of NSAID treatment and physiotherapy regimen to be maintained throughout the study. MRI will be performed during Screening period to exclude other shoulder pathologies and tears (if present) >50%. Evidence of tendinopathy should be established by a centrally read Magnetic Resonance Imaging (MRI). MRI performed within 3 months from baseline may be accepted if deemed suitable by the central reader. Shoulder x-rays will also be performed in order to rule out other shoulder pathologies. Historic x-rays will be accepted if performed ≤ 3 months prior to Baseline. - Study period 1 (Baseline to Week 16) During Study period 1, double-blinded treatment is administered over 12 weeks, reflecting 16 weeks of total drug exposure. Approximately 234 eligible participants will be randomized at Baseline (BSL) in a 1:1 ratio to one of the following arms: Arm 1 (N=117): secukinumab 300 mg s.c. at Day 1 and Weeks 1, 2, 3, 4, 8, and 12 Arm 2 (N=117): placebo at Day 1 and Weeks 1, 2, 3, 4, 8, and 12 The last dose of study treatment will be administered at Week 12; the primary outcome assessments will be performed at Week 16. Randomization will be stratified by tear status (no tear/partial tear). Participants should continue on stable NSAID pain medication and a standardized physiotherapy regimen. Reduction in NSAID dose is permitted after BSL, but participants must not increase above dose established during run-in. Use of corticosteroid injections is not permitted during this time. - Study period 2 (Follow-up period) A follow-up period of 8 weeks after the end of the treatment period is planned to assess the maintenance of effect and collect follow-up safety data up to Week 24. Investigator, site personnel, persons performing the assessments and participants will remain blinded, but Novartis clinical trial and submission teams will be unblinded after Week 16 readout. Participants should continue on stable NSAID therapy and physiotherapy during this period. Reduction in NSAID dose is permitted after BSL, but participants must not increase above dose established during run-in. Corticosteroid injections are also not permitted after Week 16. - Off-site procedures At the Investigator's discretion, participants may avail of home administration of study drug (self-administered or by a care-giver) at Week 1 and Week 3. Participant and/or caregiver would need to be trained and approved by Investigator for these administrations. Site should have confirmed contact with participant for these home administrations. Tele-visits, i.e., secure videoconferencing, between the Participant and Investigator or designated site staff may also be utilized to support administration of study drug at home. Rescue Medicine Any changes to type of NSAID taken by the participant or any increase in NSAID dosages from stable dose established during run-in period are considered prohibited throughout the duration of the study. If pain or discomfort is intolerable, participants may use non-NSAID medication including, for example, acetaminophen/paracetamol, low-dose opioids and tramadol, as needed. If the participant continues to experience intolerable pain or discomfort, then any increase to the dose of NSAID taken should be kept to an absolute minimum in terms of dosage and duration. Any changes to NSAID type and/or increase in dose will be recorded as a deviation to the protocol but would not result in withdrawal of the participant. Rational for placebo arm The placebo effect in interventional trials in the treatment of RCT is considerable; hence, a placebo control is warranted.

Investigator, site personnel, persons performing the assessments and participants will remain blinded through the Week 24 final database lock. The Novartis clinical trial and submission teams will remain blinded to the identity of the treatment from the time of randomization until the Week 16 database lock (for the primary endpoint analysis). The following methods are utilized for blinding: (1) Randomization data are kept strictly confidential until the time of unblinding and will not be accessible by anyone else involved in the study with the following exceptions: bioanalyst; (2) the identity of the treatments will be concealed by the use of study treatments that are all identical in packaging, labeling, schedule of administration, and appearance.

Change from BSL in in the Western Ontario Rotator Cuff Index (WORC) Physical Symptom Domain (PSD) score

Improving physical shoulder symptoms in participants with moderate to severe RCT at Week 16 The WORC PSD is a sub-domain of the WORC Patient-Reported Outcome (PRO) and comprises 6 questions that capture the key symptoms experienced by participants with RCT relating to pain, weakness, stiffness, and mechanical symptoms. A score of 0 is the best outcome in terms of physical symptoms and a score of 60 is the worst possible score

Proportion of participants who achieve an improvement (increase) of at least 40 points from BSL in the WORC PSD

Achieving a clinically meaningful response in improving physical shoulder symptoms in participants with moderate to severe RCT at Week 16

Proportion of participants who achieve an improvement (increase) of at least 50 points from BSL in the WORC total score

Improving symptoms caused by RCT and the associated impact on day-to-day functioning in participants with moderate to severe RCT at Week 16

Change from BSL in the Patient-Reported Outcomes Measurement Information System (PROMIS) - Short Form (SF) Upper Extremity score

Improving physical function in participants with moderate to severe RCT at Week 16. PROMIS-SF Upper Extremity measures self-reported capability of Physical Function.
