Comparing two regimens for mobilizing stem cells in multiple myeloma patients

A Prospective, Multicenter, Randomized Controlled Study of Etoposide, Cytarabine Combined With Pegfilgrastim vs. Cyclophosphamide Combined With G-CSF for Hematopoietic Stem Cell Mobilization in Newly Diagnosed Multiple Myeloma Patients

Phase 3 Interventional The Affiliated People's Hospital of Ningbo University · NCT06520176

This study is testing whether a new combination of medications can help newly diagnosed multiple myeloma patients collect enough stem cells more effectively than a standard treatment.

What this trial studies

This prospective, randomized, multicenter study evaluates the efficacy and safety of a combination regimen of etoposide, cytarabine, and Pegfilgrastim (EAP) against a control regimen of cyclophosphamide and G-CSF (CG) for mobilizing hematopoietic stem cells in newly diagnosed multiple myeloma patients. A total of 99 patients will be enrolled and randomly assigned to either the EAP or CG group. The study will compare the effectiveness of stem cell collection and monitor adverse reactions associated with both regimens. Key outcomes include the proportion of patients achieving target stem cell collection values and the cumulative collection of CD34 cells.

Who should consider this trial

Good fit: Ideal candidates are newly diagnosed multiple myeloma patients who are eligible for autologous stem cell transplantation.

Not a fit: Patients with significant cardiac issues, liver dysfunction, or those who have previously undergone stem cell mobilization may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the efficiency of stem cell mobilization in multiple myeloma patients, potentially leading to better treatment outcomes.

How similar studies have performed: Other studies have shown promise in using similar regimens for stem cell mobilization, but this specific comparison is novel.
