ThromboGenics and BioInvent Start Phase II Trial of TB-402 for Deep Vein Thrombosis Prophylaxis
News Feb 24, 2009
ThromboGenics NV and co-development partner BioInvent International announce that the first patient has been enrolled in the Phase II trial with their long-acting anticoagulant TB-402 for the prophylaxis of Deep Vein Thrombosis (DVT) following orthopaedic surgery.
TB-402, which is given as a single injection post surgery, could overcome the major drawbacks such as bleeding and the need for extensive patient monitoring associated with current anti-coagulant therapy.
TB-402 is a recombinant human monoclonal antibody that targets Factor VIII, a key component of the coagulation cascade. TB-402 is a novel anticoagulant agent, which may deliver important clinical benefits due to it only partially inhibiting Factor VIII activity even when given in very high doses. This novel mode of action is expected to reduce the risk of undesirable bleeding events and the need for patient monitoring, the two main drawbacks associated with current anticoagulants.
In addition, TB-402 is a long-acting agent which means that patients are expected to receive just one single dose after surgery to prevent the development of DVT, as opposed to all current treatment options which require daily treatment for up to several weeks.
The Phase II trial is an active (enoxaparin)-controlled, dose-escalating, multicenter, prospective, randomized, open label trial evaluating TB-402 for the prophylaxis of DVT after knee surgery.
The study will assess three different doses of TB-402 given as a single intravenous bolus injection post knee replacement surgery. The trial will enrol 300 patients across 36 centers mainly in Central Europe. The primary endpoint is the safety and efficacy of the three escalating doses of TB-402. It is anticipated that the study will conclude by the end of 2010.
Patrik De Haes, CEO of ThromboGenics, commented on the news “We are very excited about the start of the Phase II trial for TB-402. Our work to date suggests that this novel agent could represent a major advance in anti-coagulant therapy, given our expectation that it will cause fewer unwanted bleeding events and will require no monitoring of patients. This combined with its ability to be used as a “one-off” treatment could make TB-402 the anti-coagulant of choice to prevent DVT in patients undergoing surgery. Given the size of the market opportunity for TB-402 and the sales reach that will be needed to engage with the potential prescribers of TB-402, it is our intention to seek a partner to undertake the later stage development and commercialization of this exciting new agent.”
The sweet flavors’ appeal to teens is a major concern for Food and Drug Administration officials, who recently declared teen vaping an epidemic. New research shows flavorings are transforming more than marketing. The chemical additives react to e-liquid, or e-juice, creating new compounds that could trigger irritation and inflammation when inhaled.READ MORE
