Providence Health Partners — Center for Clinical Research

Currently Enrolling Trials

Every day, research uncovers new information about medical conditions and possible treatments. Volunteering to participate in a clinical research study is one way you can contribute to the understanding of diseases and the development of new therapies. At the Providence Health Partners—Center for Clinical Research, clinical studies help eligible participants to:

• Play an active role in their health care.

• Gain access to new research treatments before they are widely available.

• Help others by contributing to medical research.

Because it is part of the Providence Medical Group, the Center and its operations are managed by the same physicians you entrust with your family's health care.

Currently Enrolling Studies

• Uncontrolled Hypertension Study (Halo) — If your blood pressure is high despite taking a single anti-hypertensive medication, you may be eligible for a new clinical trial that examines if the study drug can safely lower blood pressure. Trial participants receive at no cost study-related care and medication, and may qualify for time and travel compensation. Click here for more details. To see if you qualify, please phone 937-297-8999 or email

• Treatment-Resistant Hypertension Study (Brightn) — Is your blood pressure no longer responding to medication? If you are resistant to hypertension treatment, 18 years of age or older, and take hypertension medications regularly, you may qualify for a new study on a potential new therapy for hypertension. Study-related care and medication is provided at no charge to you; you may qualify for time and travel compensation. Click here for full details. Phone 937-297-8999 or email

A clinical trial is a research study conducted with volunteers to answer specific health questions. Interventional trials determine whether experimental treatments or new ways of using known therapies are safe and effective under controlled environments. Observational trials address health issues in large groups of people or populations in natural settings.
Participants in clinical trials can play a more active role in their own health care, gain access to new research treatments before they are widely available, and help others by contributing to medical research.
All clinical trials have guidelines about who can participate. Some research studies seek participants with illnesses or conditions to be studied in a clinical trial, while others need healthy participants. Criteria for acceptance into a trial are not used to reject people personally—the criteria are only used to identify appropriate participants and keep them safe.
Informed consent is the process of learning the key facts about a clinical trial before deciding whether or not to participate. To help someone decide whether or not to participate, the doctors and nurses involved in the trial explain the details of the study. An informed consent document details the study’s purpose, duration, required procedures, risks and potential benefits, and key contact. The participant then decides whether or not to sign the document. Informed consent is not a contract, and the participant may withdraw from the trial at any time.

The ethical and legal codes that govern medical practice also apply to clinical trials. In addition, most clinical research is federally regulated with built in safeguards to protect the participants. The trial follows a carefully controlled protocol, a study plan which details what researchers will do in the study.

Yes. Most clinical trials provide short-term treatments related to a designated illness or condition, but do not provide extended or complete primary health care. In addition, by having a health care provider work with the research team, the participant can ensure that other medications or treatments will not conflict with the protocol.
Yes. A participant can leave a clinical trial at any time. When withdrawing from the trial, the participant should let the research team know about it, and the reasons for leaving the study.
