Kos Announces Completion of Patient Randomization for Jerini's Phase III Clinical Trials of Icatibant for the Subcutaneous Treatment of Hereditary Angioedema

  • Kos collaboration partner, Jerini, on schedule to file US marketing authorization application by year-end 2006 with projected launch in 2007

  • US Food and Drug Administration has granted Icatibant fast track designation and orphan drug status

  • Icatibant is first-to-market therapy in an under-diagnosed area of significant unmet need

  • Jerini plans further clinical development of Icatibant for additional indications of angioedema

  • Kos responsible for Icatibant's potential clinical development in asthma and liver cirrhosis

Icatibant is a potent and specific peptidomimetic bradykinin B2 receptor antagonist developed by Jerini AG. HAE is a rare genetic disease that can be debilitating, painful and life-threatening and is characterized by recurrent local swelling at three main sites: subcutaneous tissue, the gastrointestinal tract, and the larynx. There are approximately 10,000 diagnosed HAE patients in the European Union and the US, but the disease is believed to be significantly under diagnosed. Experts estimate the HAE patient population could be as high as 75,000. Icatibant has been granted orphan drug status and fast-track designation by the US Food and Drug Administration (FDA). HAE is the first of several indications for which Icatibant offers a potential treatment. The partnership with Jerini outlines ongoing and potential development in other forms of angioedema, asthma, and liver cirrhosis.

"We are very pleased with Jerini's timely completion of patient randomization for FAST-1 and FAST-2, placing us on track to report top-line data in the third quarter of this year, filing a marketing authorization application by year-end 2006 and projected launch in 2007," said Adrian Adams, President and CEO. "Icatibant is an exciting opportunity for Kos and is an excellent example of the continued success of our expanded business model. In particular it highlights the value of making measured investments to build our R&D pipeline through corporate development and licensing activities. The next few years represents a busy and very exciting time for Kos as far as new product introductions are concerned with the projected roll-out of optimized Niaspan® MF, the launch of Icatibant, and the introduction of Simcor® and Flutiform(TM)," Adams added.

Kos has exclusive development, marketing and distribution rights for Icatibant in North America. As a first-to-market therapy for HAE, Icatibant's subcutaneous administration and excellent safety profile demonstrated in clinical studies to date offer key advantages to patients. In addition, Kos plans to market Icatibant in a pre-filled syringe, enabling patients to self-administer the drug at the onset of an attack. Kos will enter a potential $300 million market space in North America, with orphan drug status securing seven-year US market exclusivity upon approval. To support the anticipated 2007 Icatibant launch, Kos has established a new, self-contained Allergy Business Unit that will encompass sales and marketing, medical education and commercial services functions to drive the successful introduction of Icatibant.

About hereditary angioedema (HAE)

hereditary angioedema (HAE) is a debilitating and potentially life-threatening genetic disease affecting between 1:10,000 and 1:50,000 individuals worldwide. The disease is characterized by unpredictable episodes of edema and swelling of the hands, feet, face, larynx and abdomen. Swelling of the larynx can result in suffocation. In addition, patients often have bouts of excruciating abdominal pain, nausea, and vomiting that is caused by intestinal wall swelling. The disease is caused by a genetic defect, passed from parent to child.(1)
