in Portfolio News

CAMBRIDGE, Mass., June 11, 2020 (GLOBE NEWSWIRE) -- X4 Pharmaceuticals, Inc. (Nasdaq: XFOR), a leader in the discovery and development of novel therapies targeting diseases resulting from dysfunction of the CXCR4 pathway, today announced the promotion of Renato Skerlj, Ph.D., to the position of Chief Scientific Officer. Dr. Skerlj is one of the scientific founders of X4 and co-inventor of X4’s lead drug candidate, mavorixafor. He joined the company in September 2019 as Senior Vice President, Research and Development. As Chief Scientific Officer, Dr. Skerlj will lead all research and development functions and pre-clinical development activities.

“Dr. Skerlj’s positive impact on X4 has been visible since day one,” said Paula Ragan, Ph.D., President and Chief Executive Officer of X4 Pharmaceuticals. “He has been integral to our success in the application and acceleration of our research and development capabilities and has effectively advanced our CXCR4-targeted candidates into the clinic. Dr. Skerlj’s vision and proven track record in discovering and developing small molecule drugs for rare diseases significantly strengthens our senior leadership team. We look forward to his continued contributions as we progress mavorixafor through clinical development and expand our pipeline to support the long-term growth of the company.”

Dr. Skerlj added, “This is an exciting time for X4 as we evaluate mavorixafor as a potential disease-modifying therapy for patients with WHIM syndrome and as a targeted treatment for genetically-defined blood cancers, such as Waldenström’s macroglobulinemia. In my new role as Chief Scientific Officer, I look forward to our team continuing to leverage its robust in-house research and development capabilities as we advance our pipeline and expand into additional rare disease indications.”

Dr. Skerlj has more than 25 years of experience leading the discovery and development of disease modifying small molecule drugs to treat genetically defined rare diseases. He has authored 67 publications, holds 52 patents and has advanced multiple drug candidates into clinical development.

Prior to joining X4, Dr. Skerlj held drug discovery and development leadership roles at Lysosomal Therapeutics. Previous to that, he was interim Head of Small Molecule Discovery at Genzyme and part of the executive team at AnorMED, a publicly traded company that was acquired by Genzyme in 2006. Dr. Skerlj is an accomplished drug developer, having contributed to the approval of two drugs; plerixafor, a CXCR4-targeted stem cell mobilizer approved by the U.S. Food and Drug Administration (FDA) in 2008, and ertapenem, an anti-bacterial approved by the FDA in 2001. Dr. Skerlj received his Ph.D. in synthetic organic chemistry from the University of British Columbia, and completed postdoctoral fellowships at the University of Oxford and Ohio State University.

About X4 Pharmaceuticals
X4 Pharmaceuticals is a late-stage clinical biopharmaceutical company and a leader in the discovery and development of novel therapies for the treatment of diseases resulting from dysfunction of the CXCR4 pathway, with a focus on rare diseases and those with limited treatment options. The Company’s lead candidate, mavorixafor, is a first-in-class, small molecule antagonist of chemokine receptor CXCR4 being developed as a once-daily oral therapy. X4 believes that inhibition of the CXCR4 receptor creates the potential for mavorixafor to provide therapeutic benefit across a wide variety of diseases, including primary immunodeficiencies and certain types of cancer. The efficacy and safety of mavorixafor, dosed once daily, is currently being evaluated in a global Phase 3 clinical trial in patients with WHIM syndrome, and in two Phase 1b clinical trials – in combination with ibrutinib in patients with Waldenström’s macroglobulinemia, and as monotherapy in patients with severe congenital neutropenia (SCN). X4 is continuing to leverage its insights into CXCR4 biology at its corporate headquarters in Cambridge, Massachusetts and at its research facility in Vienna, Austria, and is discovering and developing additional product candidates.
