Lexeo Therapeutics announced that key results from Phase I/II studies of its gene therapy LX2006 in Friedreich ataxia have been published in JAMA Cardiology. The published findings combine data from two independent studies totaling 17 participants, showing LX2006 was generally well tolerated with early signs of efficacy. Among participants with abnormal baseline left ventricular mass index in the mid- and high-dose cohorts, there was a 28% mean improvement at 6 months and 33% at 12 months. Cardiac biopsy data from the SUNRISE-FA trial showed all eight participants achieved increases in frataxin protein expression at three months. The pivotal SUNRISE-FA 2 study is on track to initiate in the second quarter of 2026 with topline data expected in the second half of 2027.
