By GlobalDataThe trial will assess the therapy when administered as a monthly subcutaneous injection.
As a self-administered antibody therapy, the monthly dosing schedule will ease the treatment regimen for patients.
The therapy has gained orphan drug and fast track designations from the US Food and Drug Administration (FDA).
In alignment with the funding round, Sanofi Ventures’ Jason Hafler will join Star’s board of directors, while Viking Global Investors’ Maneka Mirchandaney will assume the role of board observer.
Star Therapeutics founder and CEO Adam Rosenthal stated: “We’re making significant progress across our pipeline, highlighted by the recent initiation of our Phase III trial of VGA039 to prevent bleeding in people with all types of VWD, the most common inherited bleeding disorder, with more than 50,000 patients diagnosed and treated in the US.
“VGA039 has the potential to be transformative for VWD patients and could meaningfully reduce the treatment burden, given its once monthly subcutaneous dosing regimen, in comparison to factor replacement prophylaxis which requires two to three IV infusions per week.”
