Karonudib treatment for leukemia patients

A Phase 1 Study in Patients With Hematological Malignancies to Evaluate Safety, Tolerability and Efficacy of Karonudib

Phase 1 Interventional Thomas Helleday Foundation · NCT04077307

This study is testing a new treatment called Karonudib for people with advanced leukemia and multiple myeloma to see if it is safe and works better alone or with other standard treatments.

What this trial studies

This study aims to evaluate the safety and tolerability of Karonudib in patients with advanced relapsed or refractory hematological malignancies, including Acute Myeloid Leukemia (AML), Acute Lymphoblastic Leukemia (ALL), and Multiple Myeloma. The study will assess Karonudib both as a standalone treatment and in combination with standard care therapies. It will also investigate the pharmacokinetics of Karonudib and gather evidence of its efficacy, with overall survival being a key outcome measure.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-75 with relapsed or refractory leukemia who have exhausted standard treatment options.

Not a fit: Patients with early-stage leukemia or those who have not yet received standard treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with difficult-to-treat leukemia.

How similar studies have performed: Other studies have shown promise with similar approaches in treating hematological malignancies, but this specific treatment is novel.
