However, there is no consensus or standard regarding single versus divided dosing, and high-quality evidence is lacking. Existing randomized controlled trials have small sample sizes and inconsistent conclusions, and none have focused on Asian population characteristics (e.g., body weight and drug metabolism differences). This study aims to provide level I evidence to optimize donor experience and define the optimal administration strategy.\n\nInclusion criteria: Healthy allogeneic stem cell donors aged 18-60 years, meeting institutional standard donor screening criteria (HLA matching, normal blood counts, normal liver and kidney function, negative infection screening), and providing written informed consent.\n\nPrimary endpoint: The rate of achieving a first apheresis yield of ≥ 4 × 10⁶ CD34⁺ cells\u002Fkg (donor body weight) after 5 days of G-CSF mobilization.\n\nSecondary endpoints: The rate of achieving ≥ 2 × 10⁶ CD34⁺ cells\u002Fkg with at most one apheresis; time to myeloid, platelet, and erythroid engraftment in recipients; the proportion and composition of immune cells (CD34⁺, CD3⁺, CD19⁺, CD56⁺, etc.) in the apheresis product; donor adverse events; donor-reported outcomes; and the difference in CD34⁺ stem cell yields between single-dose and divided-dose mobilization.\n\nIntervention: G-CSF will be administered at a total dose of 10 μg\u002Fkg\u002Fday, either as a single daily injection or divided into two equal daily injections.\n\nThis study is designed to investigate whether single-dose or divided-dose G-CSF administration is superior for mobilizing healthy donors in allogeneic hematopoietic stem cell transplantation.",[27,28],"Healthy Hematopoietic Stem Cell Donor","Healthy Allogeneic Hematopoietic Stem Cell Donor",[30,31,32],"healthy allogeneic hematopoietic stem cell donor","granulocyte colony-stimulating factor (G-CSF)","allogeneic hematopoietic stem cell transplantation","RECRUITING","2026-07-13",{"date":36,"type":37},"2026-07-15","ACTUAL",{"date":39,"type":21},"2026-07-10",{"date":41,"type":21},"2029-07-10",{"name":43,"class":44},"First Affiliated Hospital of Zhejiang University","OTHER",8]
