About this study

Official title: A Prospective, Randomized, Double-blind, Phase II Study to Evaluate the Safety and Efficacy of Topical Thrombin (Human) Grifols as an Adjunct to Hemostasis During Vascular, Hepatic, Soft Tissue, and Spinal Open Surgeries

This purpose of this clinical trial was to study the safety and efficacy of Topical Thrombin (Human) Grifols as an add-on treatment to help stop bleeding during vascular, liver, soft tissue, and spinal surgical procedures.

Read the detailed description

This was a prospective, randomized, double-blind, controlled, Phase II study to evaluate the safety and efficacy of Topical Thrombin (Human) Grifols as an adjunct to hemostasis during vascular (IG1202-A), hepatic (IG1202-B), soft tissue (IG1202-C), and spinal (IG1202-D) surgical procedures. Approximately 180 subjects were randomized into 1 of 2 treatment groups in a 2:1 ratio: Topical Thrombin (Human) Grifols (120 subjects) or Bovine Thrombin JMI (60 subjects) among the 4 types of surgeries. Randomized subjects were evaluated for identification of a target bleeding site (TBS) in which control of bleeding by conventional surgical techniques (including suture, ligature and cautery) was ineffective or impractical and required an adjunct treatment to achieve hemostasis. The Investigator rated the intensity of bleeding at the TBS. Topical Thrombin (Human) Grifols or Bovine Thrombin JMI was applied to the TBS and the time to hemostasis was assessed at various timepoints during a 5-minute observation period.

Subjects were evaluated by surgery type and by integrated analysis of clinical studies IG1202-A, IG1202-B, IG1202-C, and IG1202-D.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Proportion of Subjects Achieving Hemostasis by Five Minutes After Treatment Start at the TBS

    Subjects achieving hemostasis at the target bleeding site by 5 minutes following the start of treatment without the occurrence of re-bleeding until the completion of surgical closure

    Measured: From start of treatment until 5 minutes after treatment start

Secondary outcomes (2)
  1. Cumulative Proportion of Subjects Having Achieved Hemostasis at the Target Bleeding Site by Specified Time Points

    Cumulative proportion of subjects having achieved hemostasis by each of the following time points:

    • At 3 minutes following start of study treatment
    • At 4 minutes following start of study treatment

    Measured: From start of treatment until 4 minutes after treatment start

  2. Prevalence of Treatment Failures

    Protocol-defined bleeding at the target bleeding site after the start of treatment or the use of alternative hemostatic treatments or maneuvers at the target bleeding site after the start of treatment

    Measured: From start of treatment up to surgical closure by layers of the exposed surgical field containing the TBS, a median of 34 minutes

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Human thrombin and Bovine thrombin in people with Hemostasis, run by Instituto Grifols, S.A. at 20 sites 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 8 inclusion and 17 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: finished, as of the sponsor's last update on 14 Jun 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 20 sites 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. 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 10 May 2017). 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?

Proportion of Subjects Achieving Hemostasis by Five Minutes After Treatment Start at the TBS (time frame: From start of treatment until 5 minutes after treatment start). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02014402, which also lists 1 linked publication.

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 14 Jun 2017.
