FDA Clinical Hold on CARDIO-TTR Study
FDA has placed a clinical hold on the CARDIO-TTR study being developed by GlaxoSmithKline to evaluate Ionis Pharmaceuticals’ Ionis-TTRRX in patients with TTR (transthyreitin) amyloid cardiomyopathy. Ionis says that the hold is in place while Glaxo provides answers to FDA questions about the Phase 3 study protocol stemming from Ionis’ ongoing Phase 3 NEURO-TTR study of the drug in patients with TTR familial amyloid polyneuropathy. The company says that NEURO-TTR is on track to complete in the first half of 2017.
