Title: Inducible Small RNA Expression Constructs for Targeted Gene Silencing
Patent Number: 8,198,077
Filed: Jan. 15, 2004
Lead Inventor: Thomas Tuschl, Max Plank Institute

Alnylam Pharmaceuticals said this week that it has granted Sylentis, a Spanish developer of RNAi drugs, a non-exclusive option to license certain of its RNAi-related intellectual property.

The company said the Spanish Agency for Medicines and Healthcare Products has cleared its lab to make pharmaceutical compounds for research.

Earlier this summer, the company completed a phase Ia trial, finding the agent to be safe and well-tolerated in healthy volunteers.

The drug targets adrenergic receptor beta-2 and is delivered topically to the eye.

The first portion of the study was completed a few weeks ago, according to a company official, and the drug has been shown to be safe and well tolerated.
