08.05.2013 - Belgian single chain camelidae antibody producer Ablynx has started development of an anti-IgE nanobody, code-named ALV-0962.
The Ghent-based company announced the compound will enter clinical development after Q2/2014. Ablynx believes its treatment of severe allergic asthma can outcompete Roche’s /Novartis’ marketed allergic asthma antibody Xolair (omalizumab) due to its "unique" dual mode of action. The company suggested the preclinical compound could displace receptor-bound IgE as well as binding free IgE molecules.
Due to its mode of action, Ablynx believes that ALX-0962 could address a wider patient population, including those currently not eligible to be treated with omalizumab (Xolair®). Currently, many allergic asthma treatments are in clinical development including Phase II compounds from Swedish Resistentia Pharmaceuticals AB, Takeda, Actelion or Cytos Biotechnology (CYT003-QbG10).
IgE is a key mediator in initiating an allergic reaction upon allergen exposure. IgE is a clinically and commercially validated mechanism to treat allergic asthma. Omalizumab currently is the only anti-IgE biologic approved for the treatment of patients with moderate to severe persistent allergic asthma, inadequately controlled with inhaled corticosteroids. Xolair® generated sales of $1.26bn in 2012.
