Promega Increases Stake in Benitec
Promega has taken an additional equity stake in Benitec, increasing its total ownership in the Australian expressed RNAi firm to 6.15 percent, Benitec said this week.

Alnylam Presents Preclinical Data from Hypercholesterolemia Program
Alnylam Pharmaceuticals said this week that it has presented new preclinical data from its hypercholesterolemia program showing efficacy of an RNAi inhibitor of proprotein convertase subtilisn/kexin type 9 in non-human primates.
According to the company, the data, which were presented at the XVI International Symposium on Drugs Affecting Lipid Metabolism, included an in vivo demonstration that systemic administration of an RNAi drug could silence the PCSK9 gene as measured by circulating PCSK9 plasma levels by up to 70 percent.
Additional data showed that inhibition of the gene was associated with 40 to 60 percent reductions in LDL cholesterol, a 30 to 40 percent reduction in circulating apolipoprotein B levels, and an overall decreased ratio of total cholesterol to HDL cholesterol.
