Studies
Open first, then newest update. How each study uses pbr-28 is read from its arms, and is right about nine times in ten. Ask us to read each study. These are the studies that list it as an intervention; a search of ClinicalTrials.gov also finds studies that mention it only in a description, such as earlier treatment.
