November 23, 2020 updated by: Weill Medical College of Cornell University

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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 to 99 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

Description

Inclusion Criteria:

  • Men scheduled for surgical sperm retrieval for infertility
  • Men 18 years and older who can provide informed consent
  • No documented allergy to bupivacaine or celecoxib

Exclusion Criteria:

  • Prior history of substance abuse
  • Any narcotic use within the last 3 months
  • Concomitant use of aspirin
  • Any of the following comorbidities: renal failure, heart disease, peptic ulcer disease, cerebrovascular disease, significant liver disease, untreated depression, chronic pain disorder, or bleeding diatheses

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Liposomal Bupivacaine
Participants in this arm will have a single injection of liposomal bupivacaine admixed with standard bupivacaine (266mg liposomal bupivacaine mixed with 50mg bupivacaine hydrochloride) at the conclusion of their surgical sperm retrieval procedure.
Drug: Liposomal Bupivacaine
After surgical sperm retrieval, the wound will be injected with liposomal bupivacaine (266 mg) mixed with standard bupivacaine (bupivacaine hydrochloride 50mg) for post-operative pain relief.
Active Comparator: Standard Bupivacaine
Participants in this arm will have a single injection of standard bupivacaine (100mg bupivacaine hydrochloride) at the conclusion of their surgical sperm retrieval procedure.
Drug: Standard Bupivacaine
After surgical sperm retrieval, the wound will be injected only with standard bupivacaine (bupivacaine hydrochloride 100mg) for post-operative pain relief.

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
Measure Description
Time Frame
Pain Scores 48 Hours After Surgery
Time Frame: First 48 hours after surgery

Every 8 hours in the first 48 hours post-surgery, subjects were prompted to report their pain score on the 11-point numerical pain rating scale, NRS-11 (Numerical Rating Scale, 11 points). 0 indicates no pain and 10 indicates worst possible pain.

Each subject's pain scores were then plotted against time, and the area under the curve was then computed. The minimum composite score would be 0 (no pain ever reported), and the maximum composite score would be 480 (maximum pain (score of 10) reported each time across 48 hours).
First 48 hours after surgery

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
Pain Scores 60 Hours After Surgery
Time Frame: First 60 hours after surgery

Every 12 hours in the first 60 hours post-surgery, subjects were prompted to report their pain score on the 11-point numerical pain rating scale, NRS-11 (Numerical Rating Scale, 11 points). 0 indicates no pain and 10 indicates worst possible pain.

Each subject's pain scores were then plotted against time, and the area under the curve was then computed. The minimum composite score would be 0 (no pain ever reported), and the maximum composite score would be 600 (maximum pain (score of 10) reported each time across 60 hours).
First 60 hours after surgery
Pain Scores 7 Days After Surgery
Time Frame: First 7 days after surgery

Every 12 hours in the first 7 days post-surgery, subjects were prompted to report their pain score on the 11-point numerical pain rating scale, NRS-11 (Numerical Rating Scale, 11 points). 0 indicates no pain and 10 indicates worst possible pain.

Each subject's pain scores were then plotted against time, and the area under the curve was then computed. The minimum composite score would be 0 (no pain ever reported), and the maximum composite score would be 1680 (maximum pain (score of 10) reported each time across 168 hours).
First 7 days after surgery
Narcotic Requirement
Time Frame: First 7 days after surgery
Total number of narcotic tablets required between the intervention and control arms during post-operative day 1 through 7.
First 7 days after surgery
Time to Narcotic Rescue
Time Frame: First 7 days after surgery
Time (in hours) to first rescue narcotic utilization between the two arms.
First 7 days after surgery
Pain Control Satisfaction
Time Frame: 7th day after surgery
Overall satisfaction of pain control regimen self reported on post-operative day 7. The prompt required a yes/no answer. The percent of participants answering "yes" will be compared between the two arms.
7th day after surgery
Percentage of Patients Not Requiring Any Narcotics
Time Frame: 7th day after surgery
The percentage of patients remaining opiate free by post-operative day 7.
7th day after surgery
