Sin­gle in­jec­tion of Al­ny­lam's RNAi ther­a­py re­duces Alzheimer's-linked pro­teins by 65% for six months

A sin­gle in­jec­tion of an ex­per­i­men­tal treat­ment for Alzheimer’s re­duced lev­els of pro­teins linked to the dis­ease by rough­ly two-thirds for six months, Al­ny­lam an­nounced Mon­day at a med­ical meet­ing.

But the next part of the on­go­ing study, which will test re­peat­ed ad­min­is­tra­tion of the drug, re­mains on a par­tial clin­i­cal hold in the US. That hold is be­cause of “find­ings in non-hu­man pri­mate tox­i­col­o­gy stud­ies, which were done at very high dos­es and high ex­po­sures,” Pushkal Garg, Al­ny­lam’s chief med­ical of­fi­cer, told End­points News in an in­ter­view. “We are work­ing through that with the reg­u­la­tors.”
