Alnylam Pharmaceuticals Inc., a Cambridge company looking to develop therapeutics based on RNA interference, said Monday night that it has restructured its relationship with Tekmira Pharmaceuticals Corp. of Canada with a new licensing agreement; it added that the two companies have resolved all litigation between the parties in a settlement agreement.

In a press release, Tekmira said it will receive $65 million within 10 days and is eligible to receive $10 million in near-term milestone payments expected to be received in 2013, as a result of the restructuring and new agreements.
