Assessing disease burden in patients with hairy cell leukemia

Assessment of Disease Burden in Hairy Cell Leukemia

Not applicable Interventional IRCCS Azienda Ospedaliero-Universitaria di Bologna · NCT06781515

This study is trying to see if checking for a specific gene mutation in patients with hairy cell leukemia can help predict how long they can stay healthy without treatment after their initial therapy.

What this trial studies

This is a drug-free, single-center, prospective observational pilot study focusing on patients with hairy cell leukemia (HCL). The study aims to measure the fractional abundance of the V600E B-raf gene mutation using digital droplet PCR (ddPCR) to assess minimal residual disease. It will evaluate whether the absence of this mutation at the end of treatment can predict long-term treatment-free survival. Additionally, the study will explore the relationship between the absence of mutation and the duration of response in patients who have not required treatment for at least five years after initial therapy.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with a confirmed diagnosis of hairy cell leukemia, either newly diagnosed or in remission for at least five years.

Not a fit: Patients with a concurrent second malignancy will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new method for predicting long-term survival in hairy cell leukemia patients.

How similar studies have performed: While this approach is novel in the context of hairy cell leukemia, similar methodologies have shown promise in other hematological malignancies.
