About this study

Official title: A Phase II, Randomized, Single-dose, Double-blind, Placebo-controlled Study to Investigate the Efficacy, Safety and Pharmacokinetic Profile of the CollaRx Bupivacaine Implant in Patients After Gastrointestinal Surgery

The purpose of this study is to determine whether the CollaRx Bupivacaine Implant (bupivacaine sponge) is safe and effective in reducing the amount of narcotic pain medication needed to control pain during the first 24 hours after gastrointestinal (GI) surgery.

Read the detailed description

Gastrointestinal (GI) surgery encompasses a range of surgical procedures that involve abdominal incision. Gastrointestinal surgery may be performed to treat an abdominal aortic aneurysm, ulcerative colitis, Crohn's disease, gallbladder disease, bile duct disease and morbid obesity. Although less invasive laparoscopic procedures are performed when warranted, open abdominal surgery is required for certain indications and for more complicated or advanced cases.

Bupivacaine is a local anesthetic (pain medicine) that has an established safety profile. Collagen is a protein that is found in all mammals. The CollaRx Bupivacaine implant is a thin flat sponge made out of collagen that comes for cow tendons and contains bupivacaine. When inserted into a surgical site, the collagen breaks down and bupivacaine is released at the site but very little is absorbed into the blood stream. The high levels of bupivacaine at the surgical site may result in less pain for several days after surgery.

This study will compare the amount of narcotic pain medication required after surgery in patients who receive the CollaRx Bupivacaine implant or a plain collagen sponge.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Bupivacaine Collagen Sponge in people with Pain, Postoperative, run by Innocoll at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 3 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 3 Nov 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The Total Amount of Opioid Rescue Analgesia Used (time frame: 0 to 24 hours postoperatively). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Nov 2020.
