Currently Enrolling Trials
Site Overview and Experience
Our goal at Summit Research Network is to expand scientific knowledge while maintaining the highest quality patient care.
Summit Research Network is an independent medical research organization located in the greater Portland, Oregon area. Since 1976, we remain dedicated to improving medical treatment by conducting high quality scientific research and patient care. We work in cooperation with pharmaceutical companies to develop better future treatments and better health for individuals with medical and mental health conditions. Our expanded services include the Memory Health Center within Summit Research Network to focus on dementia and other age-related memory conditions.
Our staff includes physicians; psychologists, nurse practitioners, certified clinical research coordinators, medical assistants, and support personnel.
What kind of research is done at Summit?
We perform research studies, also known as clinical trials, of approved and investigational medications. Some of these studies are undertaken to enhance our understanding of currently available medications (for example; determining optimal dose schedules). We also conduct research on medications that are not available to the general public except in research studies, and look at questions of expanded usage (for example; determining whether an established medical treatment for depression is also effective in treating anxiety).
All medications available by prescription in the U.S. must go through this highly regulated, scientific process to evaluate whether an investigational medication can be approved and made available to all.
Many of our studies involve comparisons between an investigational study medication, a commonly prescribed medication, and a placebo (inactive substance). Placebo groups are included in some of our studies because the status of patients in the placebo group provides a comparison base for evaluating the effectiveness of active medications. In addition, a surprising number of people improve when treated with placebos.
Our patients receive research-related care, evaluations, and supervision by our professional and experienced staff. A post-study treatment program may also be available to patients once their study participation has been completed. All of these services are provided at no cost to the patient and health insurance is not required for any study required visits or procedures. In addition, many of our clinical trials provide study participants with a stipend or compensation for time and travel.
