[{"type":"text","content":"X4 to host virtual investor event on Tuesday, May 16 CIS oral presentation to take place on Sunday, May 21 BOSTON, April 12, 2023 (GLOBE NEWSWIRE) -- X4 Pharmaceuticals, Inc. (Nasdaq: XFOR), a leader in the discovery and development of novel small molecule therapeutics to benefit patients with diseases of the immune system, today announced that its submitted late-breaker abstract entitled \"Results of a Phase 3 Trial of an Oral CXCR4 Antagonist, Mavorixafor, for Treatment of Patients With WHIM Syndrome\" has been accepted for oral presentation at the Annual Meeting of the Clinical Immunology Society (CIS), which is taking place May 18-21, 2023, in St. Louis, MO. New data related to clinical secondary endpoints, among other assessments, are to be presented. In addition, X4 announced that the company will host a virtual event to present and discuss new data from the 4WHIM Phase 3 clinical trial at 4:00 pm ET on Tuesday, May 16, following expected publication of conference abstracts. In November 2022, X4 announced that the 4WHIM trial had met its primary endpoint and a key secondary endpoint, and that mavorixafor was generally well tolerated in the trial, with no treatment-related serious adverse events reported and no discontinuations for safety events. New data to be presented during the event will focus on additional secondary endpoints, including the impact of oral, once-daily mavorixafor on the rate, severity, and duration of infections, among other outcomes metrics, as measured during the 52-week trial period. Additionally, the company expects to provide an update on its U.S. regulatory activities in support of its potential New Drug Application-submission for mavorixafor for the treatment of WHIM syndrome, which is expected early in the second half of 2023. The X4 live-event webcast will be accessible on the investor relations section of the X4 website at www.x4pharma.com. Following the completion of the event, a replay will be available on the website. At the CIS Conference, Dr. Raffaele Badolato, Professor of Pediatrics at the University of Brescia (Italy) and an investigator in the 4WHIM clinical trial, will present at 11:30 am CT on Sunday, May 21. Although the session will only be accessible live to conference attendees, X4 will post the slides on its website concurrent with the presentation. About Mavorixafor and WHIM ...
