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 and older (ADULT, OLDER_ADULT)

Description

Inclusion Criteria:

  • Are able and willing to provide written informed consent to participate in this study, confirmed by signing the informed consent documents
  • Adult males and females ≥18 years of age
  • Female subjects must be post-menopausal. Post-menopausal status is defined as any of the following: natural menopause with menses >1 year ago; radiation induced oophorectomy with last menses >1 year ago; chemotherapy induced menopause with 1 year interval since last menses
  • Willing and able to comply with all protocol requirements including follow-up
  • Subject must have a haemoglobin ≥ 9.0 g/dL at screening
  • Subject must have a platelet count ≥ 100,000/mm3 at screening
  • Subject is undergoing a planned open liver resection
  • Male subjects must be willing and able to use adequate contraception from enrollment through to the 30 day follow-up visit
  • During the surgery, the subject presents an identified target bleeding site (TBS) with oozing, mild or moderate bleeding, which conventional surgical techniques are insufficient to control and would otherwise be a candidate for standard haemostats
  • During the surgery, subject presents no intraoperative complications, other than bleeding, that may interfere with study assessments as judged by the investigator

Exclusion Criteria:

  • Subject is undergoing emergency surgical procedure
  • Recipient of a liver transplant
  • Females of child-bearing potential
  • Active infection at the time of the liver resection
  • International Normalized Ratio (INR) > 2.0 or APTT ratio > 2.0 at screening
  • Fibrinogen level < 1.5g/L at screening
  • History of thromboembolic disease and/or thrombophilia
  • Any other disease or condition that may affect normal blood clotting, for example thrombocytopenia, as judged by the investigator
  • A known history of anaphylaxis or allergic reaction to human albumin, PEGylated proteins, yeast or moulds, porcine products or other components in the IMP
  • Participation in another investigational drug or device research study within 30 days before and after enrolment in the current study
  • Current known or suspected alcohol and/or drug abuse or dependence at the time of screening
  • Any concurrent medical, surgical, or psychiatric condition that may, in the investigator's opinion, affect the subject's willingness or ability to meet all study requirements during the study duration
  • During the surgery, subject presents severe bleeding where use of a topical haemostat would be inappropriate
  • Subject is taking any prohibited medications
  • BMI at screening of ≥35

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.

Safety of PeproStat
Time Frame: within 30 days after surgery and study treatment
Incidence, severity, and relatedness of adverse events (AEs) and adverse drug reactions (ADRs).

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.
