ClinicalTrials.gov Studies
Summary
NIH registered a Phase 2 clinical trial (NCT07533786) evaluating the efficacy and safety of investigational drug HSK55718 for postoperative pain treatment. The multi-center, randomized, double-blind, placebo/active-controlled study plans to enroll 200 subjects undergoing abdominal surgery under general anesthesia, comparing three dose levels of HSK55718 against morphine and placebo.
What changed
A new Phase 2 clinical trial registration for investigational drug HSK55718 has been posted to ClinicalTrials.gov. The study will evaluate analgesic efficacy and safety in 200 patients undergoing abdominal surgery using a multi-center, randomized, double-blind, double-dummy design with three dose levels, morphine active control, and placebo.
Pharmaceutical sponsors and clinical investigators should monitor this trial for enrollment updates and subsequent Phase 3 trial design considerations. Healthcare providers involved in postoperative pain management may track emerging analgesic candidates through ClinicalTrials.gov registrations.
