Enrolling Clinical Trials


Non-Alcoholic Steatohepatitis (NASH) Clinical Trial

Nonalcoholic fatty liver disease (NAFLD) is a condition where fat accumulates in the liver and is not caused by heavy alcohol use. Non-Alcoholic Steatohepatitis (NASH) is a form of NAFLD in which there is an accumulation of fat in the liver along with inflammation and damage. This can cause scarring (fibrosis) of the liver and may lead to cirrhosis in which the liver is permanently damaged. Cirrhosis of the liver may lead to liver cancer.

Symptoms include:

Most have no symptoms, but some may experience:

- Weight loss
- Fatigue
- Pain

You may qualify for this no-cost clinical trial if you:

- Are 18+ years of age
- Have been diagnosed with NASH

Qualified volunteers may receive at no cost:

- Study medication
- Study-related care
- Reimbursement for your travel

Tesamorelin for Cognition in Aging HIV-Infected Persons Clinical Trial

This clinical trial is testing an FDA-approved injectable medication (Tesamorelin) to treat abdominal fat accumulation in patients with HIV. Abdominal fat accumulation is linked to memory and thinking difficulties, and previous studies suggest that Tesamorelin may be beneficial for cognitive function, but this has not been tested in HIV. PCR, Inc. is working with the University of California San Diego (UCSD) on this trial.

Atopic Dermatitis (Eczema) is a chronic disease that causes itching & inflammation of the skin. Individuals with Eczema may experience dry skin, inflammation/redness, and mild-severe itching of the skin. The increased itching may cause individuals to scratch and cause breaks in the skin, leading to an increased risk of skin infection.

Colorectal Cancer (CRC) & Advanced Neoplasia (AN) Clinical Study

This clinical study is for individuals 45-84 years of age and are scheduled to undergo a screening colonoscopy and consider as 'average risk' for colorectal cancer.

The purpose of this clinical study is to collect blood samples to better understand the biomarkers of patients with colorectal cancer and help develop a blood-based screening test. Biomarkers are biologic features found in the blood and may be related to cancer risk.

Study Includes:

- Single visit for blood sample collection prior to your scheduled colonoscopy
- Compensation for qualified participants


Health insurance and doctor referrals are not required to participate in the clinical trials & clinical studies.
