A Study to Assess the Recovery and Lifespan of Radiolabeled Autologous S303 Treated Red Blood Cells (S303 RBC)

December 3, 2015 updated by: Cerus Corporation

A Randomized, Controlled, Single-Blind, 2-Period Crossover Study to Assess the Recovery and Lifespan of Radiolabeled Autologous S303 Treated Red Blood Cells

The objective of this study is to assess the post-infusion viability of S-303 Red Blood Cells (RBC) by measuring the 24 hour post-infusion recovery and lifespan of autologous RBCs prepared with the S-303 Treatment System for RBC after storage for 35 days in comparison to conventional untreated RBCs stored for 35 days.

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

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All
