Biogen Idec Inc. (BIIB) entered a six-year research collaboration with Isis Pharmaceuticals Inc. (ISIS) to develop treatments for neurological disorders, under which Biogen will gain exclusive rights to Isis' antisense technology in the neurological space.

Isis shares were up 7.4% at $30 in recent premarket trading. Through Friday's close, the stock has more than doubled this year.

Under the latest agreement, which expands the relationship between the two drug companies, Isis will receive $100 million upfront. The deal also includes as much as $220 million in milestone payments related to the anitsense technology, which is designed to alter a gene's function. The technology can be used to silence a mutation, activate a gene to compensate for an underlying issue, or synthesize a way to effectively turn a gene "on" or "off."

Most of the $100 million upfront payment will be reflected in Biogen's third-quarter expenses for research and development.

The accord marks the fourth strategic collaboration between the two companies. Late last year Biogen inked a deal with Isis to discover and develop antisense drugs against three undisclosed targets to treat neurological or neuromuscular disorders that could see Isis receive over $630 million.

Biogen and Isis are also developing antisense drugs to treat spinal muscular atrophy and myotonic dystrophy type 1.

Isis is set to hold a conference call on the latest collaboration Monday at 11:30 a.m. EDT.

Biogen shares closed Friday at $225.18 and were inactive premarket. The stock is up 54% this year.
