Study summary

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).

Inclusion criteria

  • 1. Males and females, age 18 to 80 years, inclusive, at the time of signing the ICF.

    2. Has multivessel epicardial CAD and is clinically indicated for coronary revascularization that is best treated via elective (stand-alone, i.e., not associated with valve surgery) and on-pump CABG at high risk for incomplete revascularization as assessed by local cardiothoracic surgeon and independent Eligibility Review Committee (ERC).

    3. by standard quantitative imaging technique of 25% to 50%. 4. Anatomical findings on coronary angiography and/or stress imaging that increase the likelihood of incomplete revascularization post-CABG and that supply LV segments determined to be ischemic on pre-operative stress imaging (detailed in the ERC Charter). These include, but are not exclusively:

    a. Diffuse distal coronary artery atherosclerotic disease and/or small coronary target vessels deemed unsuitable for grafting within a major coronary artery b. Multiple segmental lesions along a defined major coronary artery c. In a major coronary artery - "missing vessel" where the vessel is not seen on an angiogram d. Major coronary arteries that are ungraftable due to a long segment of failed stents e. High likelihood of available conduits being insufficient for target lesions in major coronary arteries f. Ischemic regions identified on stress imaging that are not likely to be benefited by CABG (ischemic region greater in size than that portion of myocardium supplied by the target vessel(s) that will likely be successfully grafted). Further detailed in the ERC Charter.

    5. All participants capable of procreation with their partners must agree to use a highly effective and medically accepted method of for 6 months following the study procedure (Day 1) to avoid pregnancy. This is not required of female participants who are either:

    1. (defined as no menses for 12 months without an alternative medical cause) prior to screening. In addition, at least 2 high follicle stimulating hormone (FSH) measurements in the postmenopausal range must be used to confirm a postmenopausal state in women with less than 12 months of amenorrhea and not using hormonal replacement surgery; OR
    2. Surgically sterile (i.e., hysterectomy, bilateral salpingectomy, or bilateral oophorectomy) at least 1 month prior to Screening 6. Female participants agree to not donate oocytes and male participants must agree not to donate sperm for 6 months following administration of protocol.

      7. Capable of providing and undergoing all the required tests and procedures in the protocol.

Exclusion criteria

Exclusion Criteria:

  • 1. Any of the following:

    1. ST elevation myocardial infarction (STEMI) or cerebral vascular accident within the past 60 days prior to the Screening visit;
    2. Sustained, current systolic blood pressure (BP) less than 90 mmHg or uncontrolled hypertension (systolic BP > 180 mmHg, diastolic BP > 100 mmHg) despite maximal medical treatment;
    3. Current untreated malignant ventricular arrhythmia;
    4. Congestive heart failure (HF) within the last 60 days defined as Functional Class IV;
    5. Current mitral or aortic valvular heart disease requiring mechanical intervention anticipated during the study period (including percutaneous intervention).

      2. Participants with uncontrolled coagulation disorder (that cannot be corrected by pharmacotherapy).

      3. Participants with documented, active proliferative retinopathy from any cause (ETDRS [Early Treatment Diabetic Retinopathy Study] score >35).

      4. Indication for combination of CABG with any valvuloplasty or valvular replacement and/or arrhythmia surgery (for instance a Cox-maze IV surgical procedure for atrial fibrillation).

      5. (BMI) > 45 kg/m2. 6. \< 10 g/dL, \< 1.2 × 103 per µL, count \< 75,000 per µL, and aspartate aminotransferase > 3 × (ULN), total > 2 × ULN unless the participant has a previously known history of Gilbert's syndrome 7. Diabetic individuals with glycosylated hemoglobin () > 9.5% or with active proliferative diabetic retinopathy.

      8. A history or evidence of (HIV) or active virus (HCV), active virus (HBV).

      9. Severely immune compromised participants, including participants currently treated with chronic high dose of therapy and/or cytostatic (oncolytic) therapy.

      10. Diagnosis of, or treatment for, any cancer within the last 5 years, except for basal or squamous cell carcinoma or carcinomas in situ where surgical excision was considered curative. Past medical history of cancer is not exclusionary as long as the participant has been disease free for at least 5 years since the time of diagnosis and treatment.

      11. Known or any other to the formulation buffer used to suspend the viral vector or contrast agents used in any of the radiographic procedures, or contraindication to general anesthesia.

      12. Pregnancy or currently lactating. 13. Absolute contraindication to CMR: metallic implant (including pacemaker, or implantable cardioverter defibrillator), uncontrolled claustrophobia, severe renal dysfunction (\<30 mL/minute/1.73 m2), or on renal dialysis.

      14. Recurrent or persistent atrial fibrillation with rapid ventricular response (>100 bpm) that precludes the analysis of CMR stress imaging (to assess ischemic burden, cardiac dimensions and cardiac function).

      15. Receiving an intervention or participating in another clinical study within 30 days or within 5 half-lives (whichever is longer) of the drug prior to Screening. An exception may be made if the individual is enrolled in a nontherapeutic observational study (registry) or the observational portion of a therapeutic study where the sponsoring authority authorizes enrollment.

      16. Prior participation in any gene therapy; however, if the study was unblinded or documentation otherwise exists that the participant was randomized to the placebo control group and did not receive active gene transfer agent, the participant may be considered for this study.

      17. Has a serious or unstable medical (including unstable under adequate treatment) or psychological condition (including drugs or alcohol abuse) that, in the opinion of the Investigator (with input from the ERC as appropriate), would compromise the participant's safety or successful participation in the study or interpretation of study results.

Terms in these criteria, in plain language(22)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

LVEF (left ventricular ejection fraction)

The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

Absolute neutrophil count (ANC)

The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.

It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

HbA1c

A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

COPD

Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.

What researchers measure

Primary outcomes

  1. Change from Baseline (Day 4-6 CMR) in treated segment(s) comparing XC001 and placebo in CMR imaging parameters at Weeks 12 and 26 post-surgery.

    Endpoint at the participant level is the proportion of qualifying segments that improve at 12 and/or 26 weeks as determined by myocardial ischemic burden, as measured by the following: * Global and segmental perfusion measured as sum of 32 subsegmental American Heart Association (AHA) LV segments with myocardial ischemia at 12- and 26-weeks follow-up compared to baseline (defined as a subsegment with myocardial ischemia without subendocardial late gadolinium enhancement) * Segmental myocardial blood flow measuring extent of ischemic defect in each of 16 (combined subendocardial and subepicardial) AHA LV segments defined as below at 12 and 26 weeks follow-up compared with Baseline: * Segment is abnormal if one (subendocardial) or both subsegments are ischemic at Baseline * Segment is defined as improved at follow-up if one or both subsegments normalize To qualify for analysis of the primary endpoint, at least 3 of 32 subsegments will have will have to be ischemic on the baseline CMR.

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Aug 2025; primary completion for Dec 2026, 16 months later.

Of 26 industry-sponsored phase 2 interventional studies under Coronary Artery Disease, half reached primary completion within 15 months of starting (the median), counting those still running; a quarter within 9 and three quarters within 29. This study's planned 16 months is close to that.

Counting every sponsor, half of 55 studies reached it within 28 months; a quarter within 16 and three quarters within 39.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 12, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
