Hairy Cell Leukemia Patient Data Registry
(HCL-PDR)
What this study is about
The overall objective is to develop a clinical data registry that can be used to facilitate research with the ultimate goal of reducing the morbidity and/or mortality and improving the quality of life of patients diagnosed or living with hairy cell leukemia. With approximately 1,000 new cases of this rare disease identified in the US each year, HCL represents 2% of all cases of leukemia in adults.

The overall objective is to develop a clinical data registry that can be used to facilitate research with the ultimate goal of reducing the morbidity and/or mortality and improving the quality of life of patients diagnosed or living with hairy cell leukemia. With approximately 1,000 new cases of this rare disease identified in the US each year, HCL represents 2% of all cases of leukemia in adults. Considering the rarity of this chronic leukemia, the Hairy Cell Leukemia Foundation (HCLF), in partnership with investigators from its Centers of Excellence, seeks to develop a registry to help researchers identify new trends in outcomes, recognize the most effective treatments, discover previously unknown complications of the disease, and design clinical trials for new therapies.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
