The purpose of this study is to evaluate the safety, tolerability and explore the efficacy of a single intraoperative injection of 4975 in patients undergoing arthroscopic surgery for rotator cuff repair of the shoulder

Clinical Details

Official title: A Multicenter, Randomized, Double-Blind, Placebo-Controlled, Two-Stage Exploratory Study to Evaluate Safety, Tolerability, Efficacy, and Pharmacokinetics of Intraoperative Subacromial Injection With 4975 in Patients Undergoing Arthroscopic Rotator Cuff Repair of the Shoulder

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Treatment

Primary outcome: Pain intensity using a standard 11-point numerical rating system (NRS), which will be assessed at predefined times following surgery

Secondary outcome: Mean overall daily pain and worst daily pain. Pain intensity with physical therapy. Safety outcomes include ECG, vital signs, adverse drug reactions, and wound exams

Detailed description: This is a multicenter, randomized, double-blind, placebo-controlled, two-stage exploratory study in patients undergoing arthroscopic rotator cuff repair surgery. Stage 1) Patients will be randomized to receive either 4975 or placebo. The dose of 4975 will be escalated in a protocolized manner based on safety and tolerability. Stage 2) Patients will be randomized in a 1: 1 ratio to receive either the selected dose of 4975 or placebo. All patients will be observed in the hospital for at least two days following surgery for safety, tolerability, and efficacy assessments. In addition there will be two planned follow-up visits after hospital discharge.


Minimum age: 18 Years. Maximum age: 75 Years. Gender(s): Both.
