G‑CSF plus IL‑11 for faster blood recovery after autologous stem cell transplant

The Impact of G-CSF Combined With IL-11 on Hematopoietic Reconstitution After Autologous Hematopoietic Stem Cell Transplantation

Phase 2 Interventional Fudan University · NCT07362810

This phase 2 trial will test whether adding IL‑11 to G‑CSF improves mobilization and speeds platelet and red blood cell recovery in adults having autologous stem cell transplant for multiple myeloma or lymphoma.

What this trial studies

This randomized phase 2 intervention compares standard G‑CSF mobilization with G‑CSF combined with IL‑11 in adults preparing for autologous hematopoietic stem cell transplantation. Participants receive mobilization treatment before stem cell collection and subsequent transplant, with monitoring of blood progenitor yields and post‑transplant hematopoietic recovery. The study emphasizes megakaryocytic and erythroid progenitor counts in peripheral blood as key outcomes and tracks time to platelet and red cell engraftment. Safety and tolerability of the combination regimen are also monitored.

Who should consider this trial

Good fit: Adults (≥18) with newly diagnosed multiple myeloma or lymphoma who are candidates for autologous HSCT and have adequate cardiac, pulmonary, hepatic function and performance status are ideal candidates.

Not a fit: Patients who are pregnant or breastfeeding, have prior exposure to other mobilizing agents, active HIV/hepatitis infection, or significant uncontrolled cardiac/pulmonary disease are excluded and unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, the combination could increase mobilized platelet and red cell progenitors and shorten the time to platelet and erythrocyte recovery after transplant.

How similar studies have performed: Preclinical work showed synergy between IL‑11 and G‑CSF toward megakaryocytic/erythroid progenitors, and a small single‑center prospective study in China (ChiCTR2500100054) reported increased functional megakaryocytic/erythroid progenitors after five days, but evidence remains limited.
