Novartis International AG / Novartis reports positive opinion from CHMP for Xolair® in severe form of skin disease CSU, a debilitating form of hives and chronic itch . Processed and transmitted by NASDAQ OMX Corporate Solutions. The issuer is solely responsible for the content of this announcement.

  • CHMP granted a positive opinion for the use of Xolair® (omalizumab) as an add-on therapy for chronic spontaneous urticaria (CSU) in adult and adolescent patients 12 years and above with inadequate response to H1 antihistamines
  • Xolair showed consistent high efficacy across three Phase III CSU studies and in many cases completely cleared symptoms with safety comparable to placebo[1]-[3]
  • Up to 50% of patients do not respond to approved doses of antihistamines[4], currently the only licensed treatment for CSU in the European Union (EU)
  • CSU is a persistent, debilitating form of chronic itch, hives and angioedema affecting approximately 0.5-1% of the world's population at any given time[5]

Basel, 24 January, 2014 - Novartis announced today that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion for the use of Xolair® (omalizumab) as an add-on therapy for the treatment of chronic spontaneous urticaria (CSU) in adult and adolescent (12 years and above) patients with inadequate response to H1 antihistamine treatment. The recommended dose is 300 mg by subcutaneous injection every four weeks.

At any given time, the prevalence of chronic urticaria (CU) is up to 1% of the world's population[5], and up to two thirds of these patients have CSU[5],[6]. CSU is also known as chronic idiopathic urticaria (CIU) in the US, and is a severe and distressing skin condition characterized by red, swollen, itchy and sometimes painful hives or wheals on the skin that spontaneously present and re-occur for more than six weeks[3],[7],[8]. Up to 40% of CSU patients also experience angioedema, a swelling in the deep layers of the skin[4].

"This positive news from the CHMP brings us one step closer to providing an innovative therapeutic option from our specialty dermatology portfolio to people suffering from this chronic and debilitating disease," said Tim Wright, Global Head of Development, Novartis Pharmaceuticals. "If approved, Xolair will be the first and only licensed therapy in the EU for up to 50% of CSU patients not responding to approved doses of antihistamines."

The European Commission generally follows the recommendations of the CHMP and usually issues its final decision within two months of the CHMP opinion.

The CHMP opinion was based on positive and consistent results from three pivotal Phase III registration studies (ASTERIA I, ASTERIA II and GLACIAL) that involved nearly 1,000 patients with CSU not responding to antihistamines. Xolair 300 mg met all primary and pre-specified secondary endpoints across these studies, which showed Xolair significantly improved itch and hives, including rapid itch relief, and in many cases completely cleared symptoms[1]-[3]. Quality of life was also significantly improved for patients treated with Xolair 300 mg[1]-[3] across the Phase III study program. Negative effects of CSU on quality of life may include sleep deprivation and psychological comorbidities such as depression and anxiety[5],[9]. In these studies, the incidence and severity of adverse events (AEs) was similar between Xolair and placebo recipients[1]-[3].

Results from the three pivotal registration studies for Xolair in CSU were announced in 2013. Highlights from these studies that were previously reported include:

  • In the ASTERIA II study, 44% of patients receiving Xolair 300 mg were itch-and hive-free after 12 weeks of treatment (p<0.0001)[3].
  • In the ASTERIA I study, Xolair-treated patients experienced a rapid reduction in itch and hives as early as Week 1, with the therapeutic benefit sustained over 24 weeks of active treatment (p<0.0001)[1].
  • In the GLACIAL study, more than half of patients who had failed multiple therapies including H1 antihistamines (at up to four times the approved dose) and H2 antihistamines and/or leukotriene receptor antagonists (LTRAs) had their symptoms eliminated or suppressed with Xolair 300 mg (p<0.001)[2].

Xolair has already been approved for the treatment of CSU in four countries: Egypt, Turkey, Guatemala and El Salvador. Regulatory reviews are currently ongoing in more than 20 countries, including the US, Canada, Australia and Switzerland.

Xolair is being jointly developed by Novartis and Genentech, Inc. for CSU.

About the Pivotal Phase III Xolair CSU Studies
Three pivotal Phase III studies, ASTERIA I, ASTERIA II and GLACIAL, evaluated the efficacy and safety of Xolair in nearly 1,000 CSU patients not responding to antihistamines[1]-[3].

ASTERIA I and ASTERIA II were global, multi-center, randomized double-blind studies that evaluated the efficacy and safety of Xolair compared to placebo. The studies enrolled 323 patients and 318 patients respectively, aged between 12 and 75 with moderate to severe CSU[1],[3]. Patients were randomized to Xolair 75 mg, 150 mg or 300 mg or placebo, given subcutaneously every four weeks[1],[3]. ASTERIA I had a 24-week treatment period, with a 16-week follow-up and ASTERIA II had a 12-week treatment period, with a 16-week follow-up period[1],[3].

GLACIAL was a 40-week, global, multi-center, randomized double-blind study that evaluated the safety and efficacy of Xolair compared to placebo. It involved 335 patients aged between 12 and 75 with moderate to severe CSU despite receiving standard-of-care therapy, consisting of concomitant H1 antihistamine therapy (up to four times the approved dose) and other background medications including H2 antihistamines and/or leukotriene receptor antagonists (LTRAs)[2]. Patients were randomized to Xolair 300 mg or placebo (3:1), given subcutaneously every four weeks for a total period of 24 weeks[2].

About Xolair® (omalizumab)
Xolair is a targeted therapy that binds to immunoglobulin E (IgE). Xolair suppresses histamine-induced skin reactions, probably through its reduction of IgE and downstream effects on cellular activation mechanisms[10]. Research is ongoing to understand the mechanism of action of Xolair in CSU, which could lead to a deeper understanding of how the disease develops[4].

Xolair is currently approved for the treatment of CSU in four countries. It is approved for the treatment of moderate to severe persistent allergic asthma in more than 90 countries, including the US since 2003 and the EU since 2005 and has over 400,000 patient years of exposure. In the EU, it is approved for the treatment of severe persistent allergic asthma in children (aged six and above), adolescents and adults. In addition, a liquid formulation of Xolair in pre-filled syringes has been approved in the EU and launched in most European countries. In the US, Xolair for subcutaneous use in appropriate allergic asthma patients is co-promoted by Novartis Pharmaceuticals Corporation and Genentech, Inc.
