Tetherex Pharmaceuticals, Inc. Completes $50M Series B Financing

Funding to support Phase 2 clinical trials of the company's PSGL-1 inhibitor, SelK2, in multiple indications

PR Newswire

OKLAHOMA CITY, April 18, 2018 /PRNewswire/ -- Tetherex Pharmaceuticals, Inc., a privately held biopharmaceutical company focused on developing novel selectin inhibitor products to treat thrombosis, inflammatory diseases and cancer, today announced that the company has successfully closed on a $50 million private placement of Series B preferred stock. Proceeds from the financing will be used to conduct a Phase 2 clinical trial evaluating the company's potential, first-in-class P-Selectin Glycoprotein Ligand-1 (PSGL-1) inhibitor candidate, SelK2, in the treatment of venous thromboembolism (VTE) in patients undergoing total knee replacement surgery. In addition, Tetherex intends to use funds from the offering to conduct a second Phase 2 trial evaluating SelK2 in Crohn's disease or other inflammatory indication.

The funding was led by MPM Capital and a group of Oklahoma-based investors including Dr. Philip Jones, a member of the Tetherex Board of Directors.

"Our research suggests that SelK2 can broadly impact venous thrombosis, inflammation, and cancer where selectin/receptor-mediated cell adhesion has been shown to play a key pathologic role," said Dr. Scott Rollins, chairman and chief executive officer of Tetherex. "The additional investment by MPM Capital, a leading life sciences investor, and the overall success of this latest financing speak to the strength of the scientific data supporting the potential of SelK2 as a new, potentially first-in-class therapeutic option for several indications. We look forward to advancing SelK2 into Phase 2 clinical development later this year."
