Clinical trials

This is a 26-week (with a 26-week extension) multicenter, randomized, double-blind, placebo-controlled Phase 2 study of XC001 versus placebo. Approximately 116 participants who have CAD and have been referred for revascularization by CABG and who have, according to assessment by stress imaging multiple myocardial segments that are substantially ischemic, and that are unlikely to be fully revascularized during CABG for technical reasons, including diffuse atherosclerosis, lack of conduits, or insufficient target vessels. Patients will be randomized in a 1:1 to XC001 or placebo injections during the final stages of the CABG procedure. Patients will have a baseline CMR at day 4-6 post CABG and additional assessments in the primary study period will be performed on Day 14, and Weeks 4, 12, and 26, (and during the extension period at 52 weeks).

This is a two-part study, comprised of an initial open-label run-in phase (Part 1) in a subset of 3 subjects to provide first data regarding safety, and feasibility of the percutaneous endovascular catheter-facilitated intramyocardial delivery of XC001 in patients with RA due to obstructive CAD. Part 1 of the study is comprised of 3 subjects with RA (CCS class II-IV) who will receive 4×1011 viral particles (vp) XC001. An Independent Data Monitoring Committee (IDMC), the committee will review safety and feasibility data and approval to commence enrollment in Part 2 of the study. Part 2 is a randomized, double-blind, sham-procedure control study. Subjects with RA (CCS class II-IV) with no therapeutic options will be randomized 1:1 to either the treatment group with catheter delivery of 4×1011 vp XC001 (approximately N=53) or a sham procedure group (approximately N=53). It is estimated that approximately 106 subjects will be randomized to result in 100 evaluable subjects. All subjects enrolled in Part 1, as well as Part 2 will follow all screening and safety monitoring procedures for up to 12 months (Table 2), and will be included in the safety analysis of the study.
