COLLECT BLOOD/RESEARCH USE

This protocol is designed to provide a mechanism for the Department of Transfusion Medicine, Clinical Center to collect and process blood components from paid, healthy volunteer donors for distribution to NIH intramural investigators and FDA researchers for in vitro laboratory use. Donors meeting research donor eligibility criteria will be recruited to donate blood and blood components by standard phlebotomy and apheresis techniques. The investigational nature of the studies in which their blood will be used, and the risks and discomforts of the donation process will be carefully explained to the donors, and a signed informed consent document will be obtained. Donors will be compensated according to an established schedule based on the duration and discomfort of the donation. NIH and FDA investigators requesting blood components for research use will be required to submit an electronic (Web-based) memo of request, briefly describing the nature of the research, and providing assurance that samples provided through this protocol will be used solely for in vitro and not for in vivo research. This protocol also provides a detailed schema for careful and frequent laboratory safety monitoring of repeat research apheresis donors. Blood components for research use will be distributed with a unique product number, and the DTM principal and associate investigators will serve as the custodians of the code that links the product with a donor s identity. The nature of the in vitro studies in which the blood and components collected in this study will be used is not the subject of this protocol, and is not possible to describe, since it involves basic investigative efforts in greater than 170 different NIH and FDA laboratories. The intent of this protocol is not to approve the research itself, but to provide adequate and complete informed consent for the donor, and to assure that the education, counseling, and protection of the study subjects (research blood donors) is performed in accordance with IRB, OHSR, OPRR and other applicable Federal regulatory standards...

Collection and Distribution of Blood Components From Healthy Donors for In Vitro Research Use

Background: Many different research projects need a steady supply of human blood. Blood donated by screened, healthy people may be used to test new drugs, for example, or to learn how blood cells work. Scientists from the National Institutes of Health and the Food and Drug Administration want to collect blood from donors for use in laboratory studies. Objective: To collect blood and blood parts from healthy donors for research. Eligibility: Healthy people aged 18 years and older who weigh more than 110 pounds. They must meet the requirements to donate blood for research. Participants will be screened. A nurse will check their general health. The veins in both arms will be checked to make sure they are good for donation. Participants may donate whole blood as often as they wish, but no more than 2 cups will be taken over an 8-week period. At each visit, they will fill out a questionnaire about their health, and a small sample of blood will be tested to make sure it is safe to donate. Participants may also opt to donate only white blood cells. They will undergo leukapheresis: Blood will be taken from the body through a needle inserted into a vein. The blood will pass through a machine that separates out the white blood cells. The remaining blood will be returned to the body through a different needle. Those who donate white blood cells called granulocytes may need to take 2 drugs, including a steroid, the day before. Participants who repeat this donation will need an eye exam. Participants may remain in the study for 20 years.

CRP Apheresis in STEMI

Background: In patients with acute ST-elevation myocardial infarction (STEMI), the amount of infarcted myocardium (infarct size) is known to be a major predictor for adverse remodeling and recurrent adverse cardiovascular events. Effective cardio-protective strategies with the aim of reducing infarct size are therefore of great interest. Local and systemic inflammation influences the fate of ischemic myocardium and thus, adverse remodeling and clinical outcome. C-reactive protein (CRP) also acts as a potential mechanistic mediator that adversely affects the amount of irreversible myocardial tissue damage after acute myocardial infarction. Objective: The main objectives of the current study are to investigate the efficacy of selective CRP apheresis, using the PentraSorb®-CRP system, as an adjunctive therapy to standard of care for patients with acute STEMI treated with primary PCI. Design: Investigator-initiated, prospective, randomized, open-label (outcome assessors masked), controlled, multicenter, two group trial with a two-stage adaptive design. Innovation: Selective CRP apheresis offers potential to decrease infarct size and consequently improve outcome after PCI for STEMI. This is the first randomized trial investigating the impact of selective CRP apheresis on infarct size in post-STEMI patients. In perspective, the study design allows furthermore to collect robust evidence for the design of a definitive outcome study.
