Study summary

Despite improvements and advances in pancreas surgery, about 30-35% of patients who have pancreas surgery develop a type of complication called a pancreatic fistula. A pancreatic fistula occurs when fluid produced by the pancreas leaks into the abdomen after pancreas surgery. Patients who develop a pancreatic fistula can have poor short-term and long-term consequences.We are studying the effect of a medical device named HEMOPATCH on the development and seriousness of pancreatic fistulas. HEMOPATCH is a thin, flexible bovine protein-based pad that may improve tissue sealing where it is applied during surgery. Some small studies called case studies of between 2 and 7 patients, and two clinical trials have shown that HEMOPATCH is effective at stopping bleeding and reducing drain output after some types of surgery. However, there have been no completed clinical trials using HEMOPATCH to prevent or reduce pancreatic fistulas in patients having pancreas surgery, so we don't know if it works in this setting. Health Canada has approved the use of HEMOPATCH as a device to stop bleeding or seal other bodily fluids for procedures in which the control of bleeding or leakage of other body fluids or air by standard surgical techniques are either ineffective or impractical.

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

  • Scheduled to undergo distal pancreatectomy surgery that is open or laparoscopic, with or without splenectomy
  • Age ≥ 18 years
  • Able and willing to comply with study procedures and follow-up examinations contained within the written consent form

Exclusion criteria

Exclusion Criteria:

  • to placement of HEMOPATCH tissue sealant including: 1) Known to bovine proteins; 2) Known hypersensitivity to brilliant blue [FD\&C Blue No.1 (Blue 1)]; 3) Presence of an active infection; and 4) Known pregnancy or lactation (a negative urine pregnancy test must be obtained for women of child bearing potential during the pretreatment evaluation)

Terms in these criteria, in plain language(2)

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.

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.

What researchers measure

Primary outcomes

  1. Number of Participants With a Clinically Significant Post-operative Pancreatic Fistula (POPF)

    Incidence of clinically-significant POPF - defined as ISGPS Grade B or C POPF. Determination of Grade B or C POPF was made on the basis of confirmation of presence of pancreatic fistula (any measurable volume of drain fluid on or after postoperative day 3, with an amylase content greater than 3 times the upper normal serum value) in conjunction with a review of participants' postoperative clinical course.

    Time frame: Within 90 days post-operatively

Secondary outcomes

  1. Number of Participants With a Post-operative Pancreatic Fistula (POPF)

    Incidence of any POPF - defined as International Study Group Pancreatic Fistula (ISGPF) all grades (A, B, C). Determination of POPF grade was made on the basis of confirmation of presence of pancreatic fistula (any measurable volume of drain fluid on or after postoperative day 3, with an amylase content greater than 3 times the upper normal serum value) in conjunction with a review of participants' postoperative clinical course.

    Time frame: Within 90 days post-operatively

  2. Number of Participants Who Experienced Post-Operative Complications

    Postoperative complications graded using the Clavien-Dindo system - participants experiencing a Clavien-Dindo complication of greater than or equal to 3 were counted (grade 3 or higher is typically indicated by a procedural intervention to treat the post-operative complication). This grading system was used as a measure of 90-day postoperative morbidity.

    Time frame: Within 90 days post-operatively

  3. 90-Day Mortality Count

    Indicated by death within 90-days after surgery.

    Time frame: Within 90 days post-operatively

  4. Average Length of Stay in Hospital

    Number of days from date of surgery (POD0) to the date of discharge

    Time frame: Within 90 days post-operatively

Limitations and caveats
Broad inclusion criteria does not permit specific evaluation of patient subgroups given overall small sample size. Small sample size also introduces the potential for oversampling of high-risk cases, such as those requiring multivisceral resection.

Participant flow

78 patients were assessed for eligibility at 7 hepatopancreaticobiliary centres in Canada. Of these, 52 patients met the inclusion criteria and consented to trial participation. These 52 participants were enrolled and allocated to the investigational Hemopatch intervention.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Aug 2018 to primary completion in Oct 2020, 25 months.

Results were first posted in Aug 2021, 10 months after primary completion.

Of 324 non-industry phase 2 interventional studies under Pancreatic Neoplasms, half reached primary completion within 60 months of starting (the median), counting those still running; a quarter within 36 and three quarters within 80. This study's 25 months is below that.

Counting every sponsor, half of 393 studies reached it within 57 months; a quarter within 35 and three quarters within 80.

How these figures are worked out, and which studies are left out of them.

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 Nov 3, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
