Bioverativ Completes Acquisition of True North Therapeutics

WALTHAM, Mass.--(BUSINESS WIRE)-- Bioverativ Inc. (NASDAQ: BIVV), a global biotechnology company focused on the discovery, development and commercialization of innovative therapies for hemophilia and other rare blood disorders, today announced that it has successfully completed its acquisition of True North Therapeutics, a privately-held, clinical-stage rare disease biotechnology company. The acquisition advances Bioverativ’s vision of becoming the leading rare disease company focused on blood disorders.

“We are excited to welcome the talented True North team and combine their deep understanding of complement biology with our expertise in hematology to develop innovative therapies for people with rare blood disorders,” said John Cox, Chief Executive Officer of Bioverativ. “This acquisition strengthens our pipeline, expands our scientific competencies, and provides a significant opportunity to meaningfully impact people living with cold agglutinin disease. We also believe it has the potential to create significant long-term value for our shareholders.”

With the acquisition, Bioverativ adds TNT009, a first-in-class monoclonal antibody in development for cold agglutinin disease (CAgD), to its pipeline of novel, investigational therapies for the treatment of rare blood disorders, including hemophilia, sickle cell disease and beta thalassemia. There are no approved treatments for CAgD, which is a rare and chronic autoimmune hemolytic condition that often leads to severe anemia. People living with CAgD can suffer with a significant disease burden, including frequent blood transfusions, crippling fatigue, and an increased risk of life-threatening thrombotic events such as pulmonary embolism and stroke.

TNT009 has received breakthrough therapy designation from the U.S. Food and Drug Administration (FDA) for the treatment of hemolysis in patients with primary CAgD, and orphan drug designation from the FDA and the European Medicines Agency. Late-stage clinical development planning for TNT009, including a registrational program, is underway.

The acquisition also includes TNT020, a discovery-stage, follow-on monoclonal antibody that targets activated C1s with the potential for less frequent dosing and subcutaneous administration.

Terms of the Transaction
Bioverativ has acquired True North for an upfront consideration of $400 million plus assumed cash. True North investors are also eligible to receive additional payments of up to $425 million contingent on the achievement of future development, regulatory and sales milestones. The upfront consideration was paid through a combination of cash and debt.

About Cold Agglutinin Disease (CAgD)
CAgD is a debilitating autoimmune hemolytic anemia in which autoantibodies target red blood cells, leading to red blood cell destruction via complement activation initiated by the C1 complex, causing chronic anemia, severe fatigue and potentially fatal thrombotic events. CAgD occurs in approximately 16 people per million, affecting an estimated 5,000 people in the United States. Typically, symptom onset begins around age 60 and there are no approved therapies for CAgD. Treatment is aimed at normalizing hemoglobin levels through blood transfusions, steroids or off-label immunotoxic therapy; however, current treatment options are often intensive, incomplete, or nondurable, leaving patients dependent upon frequent transfusions, which can lead to chronic iron overload.

About TNT009
TNT009 is a first-in-class, humanized, monoclonal antibody that is designed to selectively inhibit the classical complement pathway by targeting C1s, a serine protease within the C1-complex in the complement pathway of the immune system, and directly impacting the central mechanism of CAgD. With a unique mechanism of action and high target specificity, TNT009 is designed to selectively inhibit disease processes in the classical complement pathway while maintaining activity of the alternative complement pathway and lectin complement pathway, which are important for immune surveillance and other functions.
