Smoking Vaccine

Smoking Vaccine Update:
Novartis has acquired global rights to an anti-smoking vaccine, which was developed by Swiss company Cytos Biotechnology.


In the deal Novartis gets worldwide exclusive rights for CYT002-NicQb, a therapeutic vaccine in clinical development for the treatment of nicotine addiction.

Phase II trials of the potentially first-in-class vaccine have indicated that the drug could stimulate abstinence from smoking in patients who achieved high antibody levels following vaccination, Novartis said.

The compound is set to enter Phase III trials in late 2008.

Swiss giant Novartis will be responsible for late stage clinical development, manufacturing, and commercialization of the vaccine, while Cytos is eligible to receive up to CHF 600m in upfront and potential development, regulatory approval and sales milestone payments based on the successful development and commercialization of the drug.

In addition, Cytos Biotechnology will receive royalty payments on net sales of product.

"This unique compound complements our efforts to provide a range of new treatment options to patients and physicians across a wide range of respiratory diseases," said Thomas Ebeling, chief executive of Novartis.

"Smoking remains a cause of many fatal diseases, and vaccine technology represents an important new approach to help people overcome their addiction to nicotine and stop smoking permanently."

NicQb is one of several therapeutic vaccines being developed by Cytos using its Immunodrug technology. The drug acts by inducing the body to develop antibodies that bind specifically to nicotine molecules in the bloodstream. The resulting complex is then too large to get through the blood-brain barrier, and therefore reducing the uptake of the highly addictive nicotine.

A phase I and a phase II trial have demonstrated that CYT002-NicQb has a favorable safety profile and is generally well tolerated and that it promoted and sustained long-term abstinence from smoking, when high antibody levels have been achieved upon vaccination.
