About this study
Official title: A Phase I/IIa, Open-Label, Dose Escalation Study to Evaluate the Safety and Tolerability of HiCM-188, an Allogeneic iPSC-derived Cardiomyocyte Therapy, in Adult Patients With Advanced Heart Failure
This clinical study will evaluate the safety and tolerability of HiCM-188, an investigational allogeneic induced pluripotent stem cell (iPSC)-derived cardiomyocyte therapy, in adults with advanced heart failure who are undergoing coronary artery bypass grafting (CABG) surgery.
Participants who meet the study eligibility criteria will receive a single dose intramyocardial injection of HiCM-188 during CABG surgery. The study will evaluate two dose levels of HiCM-188 using an open-label dose-escalation design. Participants will be followed for up to 12 months after treatment to monitor safety and preliminary signs of clinical effect.
Read the detailed description
This is a Phase I/IIa, open-label, dose-escalation study of HiCM-188 in adult participants with advanced heart failure. HiCM-188 is an investigational cell therapy product consisting of allogeneic human iPSC-derived cardiomyocytes intended for intramyocardial administration.
Eligible participants will receive HiCM-188 during coronary artery bypass grafting (CABG) surgery. The study uses a 3+3 dose-escalation design to evaluate two dose levels of HiCM-188: 0.5 × 10^8 cells and 1.5 × 10^8 cells. The primary objective is to evaluate the safety and tolerability of intramyocardial injection of HiCM-188. Secondary objectives include evaluation of preliminary efficacy based on cardiac function, myocardial perfusion, exercise capacity, NYHA functional classification, quality of life, and major adverse cardiac events.
Participants will be monitored during the in-hospital period after CABG surgery and HiCM-188 administration, and then followed for up to 12 months after treatment.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
HiCM-188 CellsDrug
HiCM-188 is an investigational allogeneic human induced pluripotent stem cell (iPSC)-derived cardiomyocyte therapy administered as intramyocardial injection during CABG surgery.
| Study group | Role | What they receive |
|---|---|---|
| HiCM-188 Low Dose | Experimental | Participants in this arm will receive a single low dose of HiCM-188, 0.5 × 10^8 cells, administered by intramyocardial injection during coronary artery bypass grafting (CABG) surgery. Receives: Drug: HiCM-188 Cells |
| HiCM-188 High Dose | Experimental | Participants in this arm will receive a single high dose of HiCM-188, 1.5 × 10^8 cells, administered by intramyocardial injection during coronary artery bypass grafting (CABG) surgery. Receives: Drug: HiCM-188 Cells |
What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence of Serious Adverse Events
Incidence of serious adverse events (SAEs) at 12 months post-transplant
Measured: Up to 12 months post-transplant
Secondary outcomes (9)
Change From Baseline in Left Ventricular Ejection Fraction by Cardiac MRI
Change from baseline in left ventricular ejection fraction (LVEF, %) assessed by cardiac magnetic resonance imaging (MRI). Echocardiogram may be used as an alternative if cardiac MRI is not medically appropriate or per institutional practice.
Measured: Baseline, 6 months, and 12 months
Change From Baseline in Left Ventricular End-Diastolic Volume by Cardiac MRI
Change from baseline in left ventricular end-diastolic volume (LVEDV, mL) assessed by cardiac MRI. Echocardiogram may be used as an alternative if cardiac MRI is not medically appropriate or per institutional practice.
Measured: Baseline, 6 months, and 12 months
Change From Baseline in Left Ventricular End-Systolic Volume by Cardiac MRI
Change from baseline in left ventricular end-systolic volume (LVESV, mL) assessed by cardiac MRI. Echocardiogram may be used as an alternative if cardiac MRI is not medically appropriate or per institutional practice.
Measured: Baseline, 6 months, and 12 months
Change From Baseline in Infarct Size by Cardiac MRI
Change from baseline in myocardial infarct size assessed by cardiac MRI.
Measured: Baseline, 6 months, and 12 months
Change From Baseline in Myocardial Tissue Perfusion by PET/CT or SPECT
Change from baseline in myocardial tissue perfusion assessed by positron emission tomography/computed tomography (PET/CT) or single-photon emission computed tomography (SPECT).
Measured: Baseline, 6 months, and 12 months
Change From Baseline in 6-Minute Walk Distance
Change from baseline in exercise capacity as assessed by the 6-minute walk distance (6MWD). The 6-Minute Walk Distance is measured as the distance walked in 6 minutes, with longer distances reflecting better functional exercise capacity.
Measured: Baseline, 6 months, and 12 months
Change From Baseline in New York Heart Association Functional Classification
Change from baseline in New York Heart Association (NYHA) functional classification. The New York Heart Association Functional Classification ranges from Class I to Class IV, with higher classes reflecting more severe limitation of physical activity and worse heart failure symptoms.
Measured: Baseline, 6 months, and 12 months
Change From Baseline in Minnesota Living With Heart Failure Questionnaire Score
Change from baseline in quality of life as measured by the Minnesota Living with Heart Failure Questionnaire (MLHFQ). The Minnesota Living With Heart Failure Questionnaire score ranges from 0 to 105, with higher scores reflecting worse heart failure-related quality of life.
Measured: Baseline, 6 months, and 12 months
Incidence of Major Adverse Cardiac Events
Incidence of major adverse cardiac events (MACE) during the study follow-up period.
Measured: Up to 12 months post-transplant

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing HiCM-188 Cells in people with Advanced Heart Failure and Ischemic Heart Failure, run by HELP Therapeutics Co., Ltd. at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 29 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Alex Zhang (+1 650 504 5586, Alex.zhang@helptx.com.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence of Serious Adverse Events (time frame: Up to 12 months post-transplant). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jun 2026.
