“We’re pleased to be sharing details of our ongoing Phase 3 clinical trial at ASH as we continue to recruit patients and activate study sites across the globe. The initiation of this trial was a significant milestone for the chronic neutropenia community that – unfortunately – hasn’t seen any treatment innovation in nearly 30 years,” said
The Phase 3 4WARD trial is evaluating the efficacy, safety, and tolerability of oral, once-daily mavorixafor (with or without stable doses of injectable G-CSF) in people with congenital, acquired primary autoimmune or acquired primary idiopathic CN who are experiencing recurrent and/or serious infections. The 52-week trial is a randomized, double-blind, placebo-controlled, multicenter study aiming to enroll 150 participants across 90 to 110 sites in 20 to 25 countries.
X4 will also be hosting a booth (#2106) at the conference to share information about the ongoing 4WARD clinical trial.
Additionally, in an oral presentation at the meeting, the company will present preclinical data on the potential for CXCR4 antagonism to correct peripheral blood neutropenia and bone marrow neutrophil accumulation caused by a loss-of-function in the CXCR2 pathway.

About the 4WARD Global, Pivotal, Phase 3 Clinical TrialThe 4WARD trial is a global, pivotal Phase 3 clinical trial (NCT06056297) evaluating the efficacy, safety, and tolerability of oral, once-daily mavorixafor (with or without G-CSF) in people with congenital, acquired primary autoimmune or acquired primary idiopathic chronic neutropenia who are experiencing recurrent and/or serious infections. The 52-week trial is a randomized, double-blind, placebo-controlled, multicenter study aiming to enroll 150 participants with confirmed trough ANC levels less than 1,500 cells per microliter at baseline screening and histories of two or more serious and/or recurrent infections in the prior year. The primary endpoint of the trial is based on two outcome measures: annualized infection rate and positive ANC response.
