Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are adults aged 18 and older diagnosed with hairy cell leukemia, including those with relapsed disease who have had no more than one prior therapy.
✕Probably not a fit
Patients with active infections, central nervous system metastases, or significant heart disease may not benefit from this study.

What this trial studies
This phase II trial investigates the effectiveness and side effects of cladribine and rituximab in treating patients with hairy cell leukemia, including those with recurrent disease. The study involves administering cladribine intravenously for five days, followed by rituximab weekly for eight weeks. The primary objectives include assessing the complete response rate, the eradication of minimal residual disease, and the long-term disease-free and overall survival rates. Additionally, the trial aims to identify potential predictors of treatment outcomes through molecular evaluations.
Why it matters
Potential benefit: If successful, this treatment combination could lead to improved response rates and survival outcomes for patients with hairy cell leukemia.
How similar studies have gone: Other studies have shown promising results with similar combinations of chemotherapy and immunotherapy in treating various cancers, suggesting potential success for this approach.
