FRONTIERS IN MEDICINE(2021)
摘要
Background: YF-H-2015005, a novel CXCR4 antagonist, has been proven to increase the quantities of circulating hematopoietic stem cells (HSCs), which results in an adequate collection of HSCs in non-Hodgkin lymphoma (NHL) patients.Methods: This was a multicenter, double-blind, randomized (1:1), placebo-controlled phase III clinical trial. All patients received granulocyte colony-stimulating factor (G-CSF) for up to 8 consecutive days. YF-H-2015005 or placebo was administrated on the evening of day 4 and continued daily for up to 4 days. Apheresis was conducted 9-10 h after each dose of YF-H-2015005 or placebo. The primary endpoint was the proportion of NHL patients procuring >= 5 x 10(6)/kg CD34(+) HSCs within <= 4 apheresis sessions.Results: In total, 101 patients with NHL were enrolled. The proportions of patients achieving primary endpoint were 57 and 12% in YF-H-2015005 and placebo groups, respectively (P < 0.001). Moreover, a higher proportion of YF-H-2015005-treated patients reached a minimum target collection of >= 2 x 10(6)/kg CD34(+) HSCs in <= 4 apheresis days compared to placebo-treated patients (86 vs. 38%, P < 0.001). Furthermore, the median time to collect >= 2 or 5 x 10(6)/kg CD34+ HSCs were 1 and 3 days in YF-H-2015005-treated patients, but 4 days and not reached in placebo-treated patients, respectively. No severe treatment emergent adverse events were observed in both YF-H-2015005 treatment and placebo groups.Conclusions: YF-H-2015005 plus G-CSF regimen was a tolerable combination with high efficacy, which might be used to rapidly mobilize and collect HSCs in NHL patients.
