April 16, 2024 updated by: Stefan Holubar MD MS FACS, FASCRS

SAVES-IBD: Safety & Efficacy of Aspirin vs. Standard of Care for VTE Prophylaxis After Major Surgery for Inflammatory Bowel Disease - A Pragmatic Clinical Trial

Aim to determine if aspirin 81 mg orally twice daily is effective and safe as an extended VTE chemoprophylaxis agent after major abdominal surgery for IBD patients. Study will perform an open label trial of aspirin for VTE prophylaxis compared standard of care.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

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.

Detailed Description

Patients with inflammatory bowel disease who undergo abdominopelvic intestinal surgery are at increased risk for developing venous thromboembolism, in the form of deep vein thrombosis, pulmonary embolism and mesenteric vein thrombosis for 90-days after surgery. Despite being high-risk, the standard of care is to provide mechanical and chemoprophylaxis (unfractionated heparin or low molecular weight heparin) only while they are hospitalized. There exists randomized data, in patients who have had surgery for abdominopelvic cancer, confirming the efficacy of extended post-discharge chemoprophylaxis with either unfractionated heparin or low molecular weight heparin for 28 days after surgery, but no such data exists for IBD. There has been a resistance to adopting this for IBD patients due to compliance and cost of the daily injections. However, recently, a large, multicenter, randomized trial in >3000 patients who underwent total hip or total knee replacement found that extended aspirin (81 mg) twice daily post-discharge was both equivalent and non-inferior to prophylaxis using full-strength anticoagulation with a factor Xa inhibitor. This is a prospective, multicenter, open label clinical trial to assess the safety and efficacy of post-operative venous thromboembolism (VTE) prophylaxis with aspirin 81 mg orally twice daily for 30-days after surgery for IBD compared with controls receiving standard of care.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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.

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.

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
VTE Rate
Time Frame: 30-days after discharge from hospital following IBD surgery
30-days after discharge from hospital following IBD 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.
