Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Is scheduled to undergo a unilateral open inguinal herniorrhaphy with or without mesh under general anesthesia.
  • Has an 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 .

Exclusion criteria

Exclusion Criteria:

  • 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.
  • Has a planned concurrent surgical procedure (eg, bilateral herniorrhaphy).
  • Has a or a known or suspected history of or idiosyncratic reaction to required study medications.
  • Has taken meloxicam within least 10 days prior to the scheduled surgery.
  • Has been administered bupivacaine within 5 days prior to the scheduled surgery.
  • Has been administered any local anesthetic within 72 hours prior to the scheduled surgery.
  • Has a known or suspected history of drug abuse, a positive drug screen on the day of surgery, or a recent history of alcohol abuse. Note: Subjects with a positive drug screen who are taking an allowed, prescribed medication that is known to result in a positive drug test (eg, amphetamine and dextroamphetamine for attention-deficit/hyperactivity disorder, benzodiazepine for anxiety disorder) may be eligible for participation in the study at the discretion of the Sponsor. Subjects taking any marijuana (medical or recreational) are not allowed to participate in the study.
  • Previously participated in an HTX-011 study.
  • Received an product or device in a clinical trial within 30 days or within 5 elimination half-lives.
  • Has a (BMI) >35 kg/m2.

In addition to the preceding exclusion criteria 1 through 14, subjects to be enrolled in Cohort 1 Part B, Cohort 2 Part B, or Cohort 3 who meet any of the following criteria prior to randomization will be excluded from the study:

  • Has had a prior ipsilateral inguinal 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 known or suspected daily use of opioids for 7 or more consecutive days within the previous 6 months.
  • Has taken long-acting opioids within 3 days prior to the scheduled surgery.
  • Has taken any opioids within 48 hours prior to the scheduled surgery.
  • Has initiated treatment with study medications within 1 month prior to study drug administration that can impact pain control.
  • Has been administered systemic within 5 half-lives or 10 days prior to administration of study drug.
  • Has undergone 3 or more surgeries within 12 months.
Terms in these criteria, in plain language(8)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

ASA physical status

The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 12, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
