Brief Summary:
The purpose of this clinical study is to evaluate the safety and efficacy of HS-001 CS transplanted into severe heart failure patients with underlying ischemic heart disease for 26 weeks after transplantation.

Condition or disease Intervention/treatment Phase
Heart Failure Ischemic Heart Disease Biological: HS-001 CS Device: HS-001-D needle, HS-001-D Adaptor Phase 1 Phase 2

Detailed Description:

This is a multicenter, open-label, two-group dose-escalation, phase I/II study in 10 severe heart failure patients (five in the low-dose group and five in the high-dose group) with underlying ischemic heart disease.

After screening period is completed, subjects undergo HS-001 CS transplantation. After transplantation, subjects take immunosuppressant and have efficacy/safety assessments.
