HRS-9190 versus rocuronium to maintain muscle relaxation during adult surgery

A Phase II, Multicenter, Randomized, Double-Blind, Active-Controlled Study to Evaluate the Efficacy and Safety of Bolus-Administered HRS-9190 Versus Rocuronium for Maintaining Neuromuscular Blockade During General Anesthesia in Adults Undergoing Elective Surgery.

Phase 2 Interventional Jiangsu HengRui Medicine Co., Ltd. · NCT07404579

This will test whether HRS-9190 keeps muscles relaxed as well as rocuronium in adults having elective surgery under general anesthesia.

What this trial studies

Adults scheduled for elective general anesthesia are randomized to receive either HRS-9190 or rocuronium for bolus maintenance during surgery. The primary endpoint is the time from the last dose until neuromuscular recovery to a train-of-four ratio (TOFr) ≥ 90%. Secondary endpoints include onset and duration after each dose, total time of adequate surgical relaxation, and the detailed pattern of neuromuscular recovery. Safety monitoring includes adverse events, vital signs, laboratory parameters, and other perioperative safety indicators.

Who should consider this trial

Good fit: Adults who meet the study's age, BMI, and ASA physical-status criteria, are scheduled for elective general anesthesia, and can provide informed consent are ideal candidates.

Not a fit: Patients with excluded high-risk procedures, significant neuromuscular or systemic disorders, abnormal laboratory results, known hypersensitivity, recent use of interfering medications, or other disqualifying conditions are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, HRS-9190 could provide effective neuromuscular relaxation with a favorable recovery profile and acceptable safety for adults undergoing surgery.

How similar studies have performed: Rocuronium is a well-established comparator, while investigational neuromuscular blockers have produced mixed results, so HRS-9190 is a novel candidate being tested in this Phase 2 comparison.
