QUantum Genomics Incremental Dosing in Heart Failure - QUID-HF
QUantum Genomics Incremental Dosing in Heart Failure - QUID-HF
Heart Failure (HF) a common clinical condition characterized by either by a heart that does
 not pump sufficiently or becomes stiff. A variety of mechanisms contribute to progressive
 cardiac remodeling and dysfunction.

 A new therapeutic approaches by preventing activation of the brain neuromodulatory pathway,
 may lead to improve HF.

 QCG001 is a prodrug of EC33, a aminopeptidase A (APA) inhibitor. QCG001 has been shown to be
 an antihypertensive agent in animal models.

 This study investigates the safety and efficacy of QGC001 in HF patients.
Despite advances in care, prognosis remains poor once overt Heart Failure (HF) has developed.
 HF is a common clinical condition characterized by either by a heart that does not pump
 sufficiently or becomes stiff and it is associates with higher incidences of patient illness
 and death in both case. A variety of mechanisms contribute to progressive cardiac remodeling
 and dysfunction.

 A new therapeutic approaches by preventing activation of the brain neuromodulatory pathway,
 may lead to improve HF.

 QCG001 is a prodrug of EC33, a specific and selective of the aminopeptidase A (APA)
 inhibitor. QCG001 has been shown to be an antihypertensive agent in animal models.

 This study investigates the safety and efficacy of QGC001 up-titrated form 50mg twice daily
 to a maximum of 500 mg twice daily, on patients with worsening chronic HF during 28 days and
 7 days after discontinuation (day 35).

 6 European countries are involved in this study (France, Netherlands, Germany, Norway, Poland
 and United Kingdom) including 20 investigational hospitals. Patients would be followed during
 35 days and inclusion period lasts until December 2017.
Inclusion Criteria:

 -  A signed and dated informed consent form prior to any study procedure

 -  Adult male subjects and female subjects without childbearing potential.

 -  Clinical diagnosis of CHF with history of NYHA class II-III for at least 3 months
 before randomisation.

 -  Documented left ventricular ejection fraction (LVEF) < 40% measured by any modality
 within the previous 12 months in the subject's medical history.

 -  Subjects must also have at least one local measurement of BNP level ≥ 300 pg/mL or
 NT-proBNP level ≥ 1200 pg/mL (preferred assay, local laboratory) at the screening
 visit (maximum 7 days before randomisation).

 -  eGFR > 30 mL/min/1.73 m2 (MDRD) at screening.

 -  Serum potassium < 5.0 mmol/L at screening.

 -  Systolic blood pressure < 110 mmHg (average of 3 consecutive measurements) at
 screening.

 -  Prescribed to optimal pharmacologic therapy per "ESC guidelines for the diagnosis and
 treatment of acute and chronic heart failure 2016", or based on the updated current
 clinical practice, unless contra-indicated or not-tolerated, and on a stable dose for
 at least 30 days prior to enrolment (the dosage of the drugs cannot be increased or
 decreased respectively by more than double or half of initial dosage).

 -  Taking oral loop diuretics at doses < 250 mg furosemide daily (or equivalent).

 Exclusion Criteria:

 -  BMI > 45 kg.m-2.

 -  Patients who require the use of HF IV therapy or oral furosemide > 250 mg (or
 equivalent) at any time during the 48 hours immediately before randomisation.

 -  Patients with unstable angina, myocardial infarction, PTCA, coronary artery bypass
 graft, cerebral vascular accident, or transient ischemic attack within previous 3
 months (90 days) before enrolment.

 -  Patients whose primary cause of heart failure is mitral or aortic valve disease or
 congenital heart disease or hypertrophic obstructive cardiomyopathy or infiltrative
 cardiomyopathy (e.g. amyloidosis, sarcoidosis) or myocarditis.

 -  Patients with "new" permanent atrial fibrillation (AF), discovered within 3 months
 prior to randomization.

 -  Heart rate > 110 beats/min at screening.

 -  Patients scheduled for Pacemaker (including ICD, CRT), Angioplasty, CABG or LVAD
 within the next 3 months.

 -  Patients with severe documented chronic obstructive lung disease (COPD), defined as
 chronic need for oxygen therapy

 -  eGFR < 30 mL/min/1.73 m2 (MDRD) at screening.

 -  Decrease in eGFR greater than 20% within 3 weeks prior to the screening visit.

 -  Serum potassium > 5.0 mmol/L at screening.

 -  Systolic blood pressure < 110 mmHg or with signs or symptoms of hypotension.

 -  Symptomatic hypotension or orthostatic hypotension defined by a decrease of systolic
 blood pressure of more than 30 mm Hg in the standing vs. sitting position at screening
 and at the basal SBP of the D0 (before having taken the study medication).

 -  A marked baseline prolongation of QT/QTc interval (e.g. repeated demonstrated of a QTc
 interval > 450 ms) AND QRS < 100 ms. In case of QRS enlargement > 100 ms (i-e bundle
 branch block, pacemakers) QT does not accurately reflect repolarization and may not be
 calculated.

 -  A history of additional risk factors for Torsade de Pointes (TdP) (e.g. hypokalemia,
 family history of long QT Syndrome).

 -  The use of concomitant medications that prolong the QT/QTc interval.

 -  Insulin-requiring diabetic patients (including type 1 Diabetes).

 -  History of angioneurotic edema.

 -  Severe liver failure at screening defined by a value of ALAT and/or ASAT≥ 5 from the
 normal value.

 -  Patients involved in any interventional clinical study, patients enrolled in
 Registries and/or in non-interventional studies may participate.

 -  Patients who take an investigational or non-approved treatment.

 -  Women of childbearing potential.

 -  Patients with a prior cardiac transplant or patients currently on the list for cardiac
 transplantation.

 -  Patient with hypersensitivity to the active substance or to one of the other
 components of the trial preparation.

 -  Patients in whom an allergy requiring chronic treatment is known or exists.

 -  Patients with a history of previous illnesses of neurological or psychiatric nature
 that affect the Central Nervous System.

 -  Patients with a life expectancy of less than 12 months per physician judgment.

 -  Frail patient who, in the opinion of the investigator will not be able to follow the
 protocol.
