To evaluate the safety of retrograde coronary sinus infusion (RCSI) of a novel triple-effector plasmid (INXN-4001) in outpatient LVAD recipients as assessed by incidence of all study intervention-related adverse events occurring up to 6 months post-RCSI (primary endpoints), and to evaluate general safety by assessing incidence of cardiac specific adverse events and the incidence of related serious adverse events at intervals up to 12 months post-infusion (or until cardiac transplantation or death).
This is a first-in-human, phase I, open label, safety study of INXN-4001 delivered via RCSI in patients with outpatient LVAD. Twelve stable patients with implanted LVAD for mechanical support of end stage heart failure have been allocated into 2 cohorts (6 subjects each) to evaluate the safety of infusing the same amount of INXN-4001 (80mg) in 2 volumes (40mL and 80mL) at 20mL/min rate. Ongoing safety assessments include clinical labs, physical exams, ECG and medical history collected during clinic visits at: pre-treatment, day 3, then 1, 3, 6, 9, and 12 months after dosing via RCSI. During visits, subjects complete the KCCQ questionnaire and are evaluated via 6-min walk test (6MWT) prior to and during an LVAD wean interval. Daily activity data is collected throughout the study using a wearable biosensor (Actigraph).
