for the development of RNA interference therapeutics. Isis also has the potential to receive milestone and royalty payments on drugs that utilize the Isis technology licensed to Alnylam.

(VICL)

rose 15% after the company agreed to grant Merck renewable options for the rights to use its patented gene delivery technology for additional cancer targets.

Additionally, Merck has a fixed-term option to exclusively sublicense, on terms to be negotiated, Vical's electroporation-enhanced delivery technology for use with HIV vaccines.

"Merck's exercise of the option for the additional targets would result in an option exercise payment to Vical, and further development may lead to milestone and royalty payments, along with an opportunity for co-promotion," Vical said.
