For the second time this year, X4 Pharmaceuticals is enacting a “strategic restructuring” initiative, in which it will let go of half of its employees in a bid to “sharpen operational focus and align resources” with its long-term strategy, These most recent staffing cuts are expected to affect some 50 employees. The strategic push will cost the company $3.3 million in one-time expenses for severance and other termination-related payments. Annualized savings are expected to hit $13 million, according to the SEC filing. X4 is also trimming its masthead. The biotech’s Board has terminated Chief Operating Officer Mary DiBiase, Chief Commercial Officer Mark Baldry and Chief Legal and Compliance Officer Natasha Thoren, all effective Sept. 15. A day later, Chief Medical Officer Christophe Arbet-Engels stepped down from his post.
