Clinical Trials

Clinical trials and research studies offer an opportunity for patients to participate in scientific and drug development research. In a clinical trial, participants receive specific interventions according to the research plan or protocol created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or changes to participants’ behavior, such as diet. Researchers will need your input through various surveys the Registry team will ask you to complete. You are the PSC patient's voice.

One important function of the Registry is to assist in connecting PSC patients with clinical trials or studies for which they may be eligible. Based upon a Registry participant’s answers to the patient surveys, a participant may receive an email with information about a clinical trial that is recruiting PSC patients. You can also visit this page anytime to see the list of clinical trials conducted by drug developers working with the PSC Partners Patient Registry team. 


PSC Partners is collaborating with pharmaceutical companies planning and conducting clinical trials by adding your patient perspective to the trial protocol; by representing the patient voice throughout the drug development process; and by sharing clinical-trial information with the PSC community. Check this site often, as new clinical trials will be added as soon as they launch. The following clinical trials and studies are recruiting PSC patients. Contact the study for up-to-date information.

An overview of the phases of clinical trials can be found here (source FDA).
