Chronic Pruritus of Unknown Origin 

Living with Chronic Pruritus of Unknown Origin 

Chronic Pruritus of Unknown Origin (CPUO) is a condition characterized by persistent itching  that lasts for six weeks or longer without an identifiable underlying cause. Unlike itching that  occurs as a symptom of another skin condition or medical illness, the cause of CPUO remains  unknown despite a thorough medical evaluation. 

People living with CPUO often experience ongoing itching that can range from mild to severe  and may affect large areas of the body. The constant urge to scratch can lead to irritated skin,  sleep disturbances, difficulty concentrating, and interfere with work, daily activities, and overall  quality of life. For some individuals, the ongoing discomfort can also affect emotional well being, causing frustration, anxiety, or embarrassment. While treatments such as moisturizers,  antihistamines, topical medications, or other prescribed therapies may help some people, others  continue to experience persistent itching despite ongoing care. 

How Clinical Research Advances Treatment 

Researchers are studying investigational medications—including oral therapies, injectable  biologics, and other targeted treatments—to determine whether they may help reduce itching,  improve symptom control, and enhance quality of life for people living with chronic pruritus of  unknown origin. These studies also help researchers better understand the underlying causes of  chronic itching and evaluate the long-term safety and effectiveness of potential new treatment  options. 

Study Costs & Compensation 

If you qualify for a clinical research study, study-related care, study medication, and other  study-related procedures are typically provided at no cost. You may also be reimbursed or  compensated for time and travel. 

Eligibility & Enrollment Process 

Who May Be Eligible 

Depending on the study, eligibility may be based on factors such as: 

✓ Having a diagnosis of Chronic Pruritus of Unknown Origin.

✓ Be male or female adults (18+) for most available studies.
