Ex­pand­ed In­tel­lia CRISPR da­ta set up show­down with Pfiz­er, Io­n­is and Al­ny­lam in not-so-rare dis­ease

Eight months af­ter de­liv­er­ing land­mark re­sults with one of the first CRISPR clin­i­cal tri­als of its kind, In­tel­lia an­nounced the ex­per­i­men­tal ther­a­py held up in a larg­er group of pa­tients and over a longer pe­ri­od of time.

In the ini­tial study, In­tel­lia showed a sin­gle in­fu­sion of its gene-edit­ing ther­a­py could low­er the amount of tox­ic pro­tein six pa­tients with a rare and fa­tal ge­net­ic dis­ease pro­duce by an av­er­age of 52% or 87%, de­pend­ing on the dose. It was the sec­ond tri­al to use CRISPR di­rect­ly in pa­tients, and the first to de­liv­er da­ta, clear­ing a ma­jor test for the No­bel-win­ning tech­nol­o­gy.
