Safety Study of Chimeric Natriuretic Peptide(CD-NP) in Stable LVAD Patients


  • Study type

  • Study phase

  • Study IDs

  • Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
  • During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study

The most promising chimeric natriuretic peptide designed and studied by our group has been CD-NP which has anti-fibrotic and cardioprotective properties in vivo, vitro and in normal volunteers and human heart failure patients. Since left ventricular assist device (LVAD) can not reverse remodeling of the heart whereas it can improve hemodynamics, CD-NP may be novel anti-fibrotic and anti-remodeling drug as co-therapy during LVAD support.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.

Inclusion Criteria

  • Male and non-pregnant/post-menopausal female, ages 18-90, in end-stage Heart Failure (HF) with LVAD support who are stable in the healed stage after at least 3 months from the LVAD implant (Destination therapy only) (the post-menopausal state is defined as the absence of menses for ≥ 1 year and serum follicle-stimulating hormone ≥ 20 IU/L; sterilization in the female is defined as bilateral tubal occlusion for ≥ 6 months, bilateral oophorectomy, or complete hysterectomy)
  • Be willing to provide informed consent.

Exclusion Criteria

  • Known allergy or other adverse reactions to exogenous natriuretic peptides (CD-NP or its components, nesiritide, other natriuretic peptides, or related compounds).
  • Women who are pregnant, or breast-feeding.
  • Having received nesiritide within 7 days prior to prior to entry into the study.
  • Having received any investigational drug or device within 30 days prior to entry into the study.
  • Clinically unstable patients (e.g. mean blood pressure < 70 mmHg, ongoing requirement for vasopressors, or mechanical ventilation).
  • Recent hospitalization for decompensated HF or recent defibrillation for cardiac resuscitation within 30 days prior to randomization.
  • Patients with guarded prognosis who are unlikely to derive meaningful benefit from CD-NP
  • Presence of cardiac lesions or comorbidities that may contraindicate the use of natriuretic peptides, such as clinically significant cardiac valvular stenosis, hypertrophic cardiomyopathy, restrictive cardiomyopathy, constrictive pericarditis, primary pulmonary hypertension, or uncorrected congenital heart disease that contraindicates the use of vasodilators.
  • Symptomatic carotid artery disease, known critical carotid stenosis, or stroke within the past 3 months
  • Clinically significant renal artery stenosis
  • Baseline hemoglobin < 9.0 g/dl.
  • Serum sodium < 130 mEq/L, potassium < 3.6 milliequivalents per Liter (mEq/L), or magnesium < 1.5 mEq/L.
  • Elevated aspartate aminotransferase (AST) or alanine aminotransferase (ALT) at least 5 times the upper limit of normal or bilirubin at least 5 times the upper limit of normal
  • Creatinine clearance (CrCl) < 30 ml.min-1.1.73m-2, as calculated by Cockcroft-Gault formula(35) and adjusted for body surface area within 3 months or at screening, or requirement for dialysis.
  • History of alcohol or drug abuse within the past 6 months.
  • Inability to communicate effectively with study personnel.
  • BMI >40
