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

This "first-in-human" Phase I, single-center, dose escalation study (using 3 dose levels) is proposed to assess the safety of infusing reconstituted lyophilized human plasma (LyP). The study design incorporates plasmapheresis-derived autologous plasma (FFP) for infusion(s) to eliminate variables and events known to be related to allogenic transfusion. Subjects will be enrolled at a blood center and provide autologous FFP that will be shipped to the sponsor site and used as the starting material to manufacture LyP. Once manufacturing is complete, the LyP (autologous) will be returned to the blood center for reconstitution and infusion into subjects. Maximum dosage within this study will approach "massive transfusion" (1 liter in Cohort 3) to obtain a preliminary assessment of safety. One half of the FFP obtained from subjects in Cohort 3 (only) will be shipped to the sponsor and returned to the site (but not manufactured into LyP) to serve as the control (autologous FFP).

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.

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 to 55 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

  • Unwilling or unable to comply with the requirements of this protocol, including the presence of any condition (physical, mental or social) that is likely to affect the subject's return for follow-up visits on schedule
  • Other unspecified reasons that, in the opinion of the Investigator, make the subject unsuitable for enrollment
  • Subject is institutionalized because of legal or regulatory order

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Lyophilized Plasma
Biological: Lyophilized Plasma
Lyophilized Plasma is serves as a source of plasma proteins for subjects who are deficient in plasma proteins. The donor and recipient are the same person, therefore the process is autologous. HemCon's lyophilized plasma originates from FFP from screened individual donors to significantly reduce the risk of bloodborne disease transmission and undesired transfusion-associated reactions. Each single-donor unit is tested (per required of the blood supply) to reduce the risk of transmission of infectious agents and hence, maximize subject safety.
Active Comparator: Fresh Frozen Plasma
Other: Fresh Frozen Plasma
The fluid portion of one unit of human blood that has been centrifuged, separated, and frozen solid at -18 °C (-0.4 °F) (or colder) within 6 hours of collection.

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
To assess the safety and tolerability of increasing doses of infused autologous units of LyP in normal healthy volunteers and to define possible LyP adverse reactions.
Time Frame: 1 day, 7 day, 14 day, and 28 day follow-ups after infusion.
1 day, 7 day, 14 day, and 28 day follow-ups after infusion.

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.
