Study of Post-Herniorrhaphy Non-opioid MMA Regimens

May 8, 2026 updated by: Heron Therapeutics

A Phase 3b, Randomized, Open-Label Study of HTX-011 as the Foundation of a Non-opioid, Multimodal Analgesic Regimen to Decrease Opioid Use Following Unilateral Open Inguinal Herniorrhaphy

This is a Phase 3b, open-label study to assess postoperative opioid use in subjects undergoing unilateral open inguinal herniorrhaphy with intraoperative administration of HTX-011 and a postoperative non-opioid multimodal analgesic (MMA) regimen. The study will be conducted in 2 sequential parts: Part 1 is randomized and Part 2 is Investigator's preference for MMA regimen.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Inclusion Criteria:

  • Is scheduled and medically fit to undergo an elective unilateral open inguinal herniorrhaphy with mesh under deep sedation or general anesthesia; no neuraxial technique (eg, no spinal or epidural).
  • Has an American Society of Anesthesiologists (ASA) Physical Status of I, II, or III.
  • Female subjects are eligible only if not pregnant, not lactating, not planning to become pregnant during the study, sterile; or using acceptable contraceptives.

Exclusion Criteria:

  • Has a planned concurrent surgical procedure (eg, bilateral herniorrhaphy).
  • Has a pre-existing concurrent acute or chronic painful physical/restrictive condition expected to require analgesic treatment in the postoperative period for pain.
  • Has a contraindication or a known or suspected history of hypersensitivity or clinically significant idiosyncratic reaction to required study medications.
  • Part 1 only: Has known or suspected daily use of opioids for 7 or more consecutive days within the previous 6 months. Part 2 only: Has known or suspected history of persistent opioid use, defined as daily, or almost daily, use of opioids for a period of at least 30 days within the previous 6 months.
  • Has taken any opioids within 24 hours prior to the scheduled surgery.
  • Has a known or suspected history of drug abuse, has a positive drug screen on the day of surgery, consumes 3 or more alcoholic drinks every day, or has a recent history of alcohol abuse.
  • Has a medical condition such that, in the opinion of the Investigator, participating in the study would pose a health risk to the subject or confound the postoperative assessments .

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Proportion of Subjects Who do Not Receive an Opioid Prescription Through the Day 15 Visit
Time Frame: Through Day 15
Through Day 15

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Proportion of Subjects Who do Not Receive an Opioid Prescription at Discharge
Time Frame: At discharge
Proportion of subjects who do not receive an opioid prescription at discharge (between 2 and 3 hours after surgery on average).
At discharge
Proportion of Subjects Who do Not Receive a Postdischarge Opioid Prescription, Through the Day 15 Visit.
Time Frame: Postdischarge through Day 15
Postdischarge through Day 15
Pain Intensity Scores at the Time of Discharge
Time Frame: At discharge
Pain intensity scores were assessed at discharge (between 2 and 3 hours after surgery on average) using an 11-point Numeric Rating Scale (NRS) (0-10) where 0 represents "no pain" and 10 represents "worst pain imaginable". NRS scores are recorded with activity (NRS-A), sitting up from a resting position.
At discharge
Number of Oxycodone Pills Taken Between Discharge and the Day 15 Visit
Time Frame: Postdischarge through Day 15
Postdischarge through Day 15
Mean TSQM-9 Scores
Time Frame: Day 15 plus or minus 2 days
The TSQM-9 contains 9 items which make up the Effectiveness, Convenience, and Global Satisfaction domains; each domain includes 3 items. Scores for each domain were computed by adding the TSQM items in each domain and then transforming the composite score into a value ranging from 0 to 100, with higher scores indicating higher satisfaction.
Day 15 plus or minus 2 days

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures.
