Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

Objective: To gather safety and efficacy BioRBC data from adult subjects who previously developed transient BioRBC antibody responses by redosing them and observing for adverse clinical or laboratory (i.e., a positive BioRBC antibody titer) outcomes to determine if RBC kinetic study results differ from the previous study. Hypothesis: BioRBC survival studies performed in adult subjects who previously developed a transient BioRBC antibody response will: 1) be associated with no adverse clinical or laboratory events; 2) experience a second transient, BioRBC antibody response; and 3) display a pattern of RBC survival that is identical to their prior dosing with BioRBCs at the same dose.

A profile link is shown only when the registered name resolves to a person record with a confident, namesake-checked match; ambiguous names stay unlinked.

Sites

1 registered facility, with the per-site recruitment status where the registry publishes one. ClinicalTrials.gov does not publish per-site enrollment counts.

Site investigator names are published by ClinicalTrials.gov only while a study recruits, so completed studies list sites without them.
