Summary

This study tested a new drug called MR-107A-02 for treating acute pain after hernia repair surgery. About 579 adults took part, comparing the drug to a placebo and to tramadol, a standard painkiller. The goal was to see if MR-107A-02 reduces pain intensity and the need for extra opioid rescue medication.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
MR-107A-02 (a pain-relief drug)
What this could lead to
If it works, this could offer a new option for managing pain after hernia surgery, possibly reducing the need for opioid rescue medication.
What could go wrong
This is a completed Phase 3 trial, but results are not yet published. The drug may not prove more effective than existing treatments like tramadol, and all pain drugs carry side effects such as nausea or dizziness.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Main Inclusion Criteria: 1\. Requirement for unilateral open inguinal herniorrhaphy with mesh under general anesthesia. 3\. Has an American Society of Anesthesiologists Physical Status of I, II, or III. 4\. Pain Intensity (PI) using NRS-R ≥4 at any given timepoint during the 5 hours following end of surgery in the eligibility assessment as well as in the baseline assessment (NRS-R and NRS-A) immediately pre-dosing. 5\. Rating of moderate or severe pain on a 4-point categorical pain rating scale (i.e., none, mild, moderate, severe) during the 5 hours following end of surgery. 6\. Able to understand and complete the study requirements (including literacy, to enable diary and questionnaire completion), provide written informed consent, and agree to abide by the study protocol and its restrictions. Main Exclusion Criteria: 1. Previously dosed with this formulation of MR 107A 02. 2. Had any prior inguinal hernia repair in the past 24 months. 3. Has a planned concurrent surgical procedure (e.g., bilateral herniorrhaphy). 4. Has a pre-existing concurrent acute or chronic painful physical/restrictive condition expected to require analgesic treatment in the postoperative period for pain that is not strictly related to the herniorrhaphy, and which may confound the postoperative assessments. 5. Known hypersensitivity to aspirin, NSAIDs, or other medication used in the study. 6. Body mass index (BMI) \>40 kg/m2 at screening. 7. Body weight of \<43 kg (105.8 lbs) at screening. 8. History of GI bleeding or peptic ulcer disease. 9. Known active inflammatory bowel disease, e.g., Crohn's Disease or ulcerative colitis. 10. A history of bleeding disorders that may affect coagulation. 11. Subjects with prior stroke or transient ischemic attack in the past 12 months prior to screening.
