A Randomized, Double-blind Controlled Study Comparing LCZ696 to Medical Therapy for Comorbidities in HFpEF Patients (PARALLAX)

October 7, 2021 updated by: Novartis Pharmaceuticals

A 24-week, Randomized, Double-blind, Multi-center, Parallel LCZ696 on NT-proBNP, Exercise Capacity, Symptoms and Safety Compared to Individualized Medical Management of Comorbidities in Patients With Heart Failure and Preserved Ejection Fraction

The purpose of this study is to demonstrate the superiority of LCZ696 over individualized medical therapy for comorbidities in reducing N-terminal pro-brain natriuretic peptide (NT-proBNP) and improving exercise capacity and HF symptoms in patients with heart failure with preserved ejection fraction (HFpEF).

Study Overview

Detailed Description

This study was a 24-week, randomized, double-blind, multi-center, parallel group, active controlled study to evaluate sacubitril/valsartan compared to individualized medical therapy on NT proBNP, exercise capacity, symptoms and QoL in patients with heart failure and preserved left ventricular ejection (HFpEF) fraction (LVEF > 40%). Patients were initially stratified into one of three strata according to prior treatment for comorbidities: Angiotensin converting enzyme inhibitor (ACEi), angiotensin receptor blocker (ARB) or no prior renin angiotensin system inhibitors (RASi). Patients in each stratum were randomized in a 1:1 ratio and received either sacubitril/valsartan or comparator (i.e.

enalapril for patients in ACEi strata, valsartan for patients in the ARB strata and placebo for patients in the No RASi strata). There was no designated proportion of patients planned in each stratum; the strata were populated based upon the patient's prior treatment regimen. The study consisted of a screening epoch of up to 2 weeks and a randomized treatment epoch of 24 weeks, which included a 1 to 4 week study drug up-titration epoch followed by a 20 to 23 week maintenance epoch. Uptitration to target doses was recommended to occur within the first four weeks of the study, and was performed by Investigator's discretion based on the patient's clinical status.

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • NYHA class II-IV
  • Structural heart disease (left atrial enlargement or left ventricular hypertrophy) documented by echocardiogram.

  • Patients on ACEi or ARB therapy must have a history of HTN

Exclusion Criteria:

  • Any prior measurement of LVEF ≤ 40%, under stable conditions
  • Acute coronary syndrome (including MI), cardiac surgery, other major CV surgery within 3 months , or urgent percutaneous coronary intervention (PCI) within 3 months or an elective PCI within 30 days prior to study entry
  • Any clinical event within the 6 months prior to Visit 1 that could have reduced the LVEF (eg MI, coronary artery bypass graft [CABG]), unless an echo measurement was performed after the event confirming the LVEF to be >40%
  • Current (within 30 days from Visit 1) acute decompensated HF requiring therapy.
  • Current (within 30 days from Visit 1) use of renin inhibitor(s), dual RAS blockade or LCZ696
  • History of hypersensitivity to LCZ696 or its components
  • Patients with a known history of angioedema

  • Systolic blood pressure (SBP) ≥ 180 mmHg at study entry, or SBP >150 mmHg and <180 mmHg at study entry unless the patient is receiving 3 or more antihypertensive drugs, or SBP < 110 mmHg at study entry.
  • Patients with HbA1c > 7.5% not treated for diabetes
  • Patients with prior major organ transplant or intent to transplant (ie on transplant list)
  • eGFR < 30 ml/min/1.73 m^2 as measured by MDRD at screening

  • Pregnant or nursing women or women of child-bearing potential unless they are using highly effective methods of contraception

Other protocol-defined inclusion/exclusion criteria may apply.

Study Plan

This section provides details of the study plan, including how the study is designed and what the study is measuring.

How is the study designed?

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Quadruple

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: sacubitril/valsartan (LCZ696)

All patients who fulfill the inclusion/exclusion criteria will be stratified before randomization based upon prior therapy for comorbidities to one of 3 strata: ACEi, ARB or no RASi. Patients in the ACEi strata will receive LCZ696 or enalapril. Patients in the ARB strata will receive LCZ696 or valsartan. Patients in the no RASi strata will receive LCZ696 or matching placebo.

Patients in the ACEi and ARB strata will take two pills twice daily for each dose: one tablet from the LCZ696 pack and one tablet from the comparator pack. Patients in the no RASi strata will take only one tablet twice daily (LCZ696 or matching placebo).

In the LCZ696 arm, patients will receive active LCZ696 in titrated doses from level 1 up to level 3 (50 mg, 100 mg and 200 mg twice daily orally).

Sacubitril/valsartan is available as 24 mg/26 mg, 49 mg/51 mg, 97 mg/103 mg, respectively in tablet form to be taken orally
Placebo to match enalapril 2.5 mg, 5 mg, 10 mg tablet form to be taken orally
Placebo to match valsartan 40 mg, 80 mg, 160 mg tablet form to be taken orally
Active Comparator: Comparator

Patients randomized to the comparator arm will receive either enalapril (ACE stratum) valsartan (ARB stratum) or LCZ696 matching placebo (no RASi stratum).

Patients in the ACE stratum randomized to comparator, will receive enalapril in titrated doses from level 1 up to level 3 (2.5 mg, 5 mg and 10 mg twice daily).

Patients in the ARB stratum randomized to comparator will receive valsartan in titrated doses from level 1 up to level 3 (40 mg , 80 mg and 160 mg twice daily).

Patients in the no RASi stratum randomized to comparator will receive LCZ696 matching placebo.

Enalapril is available as 2.5 mg, 5 mg, and 10 mg tablet form to be taken orally
Valsartan is available as 40 mg, 80 mg, 160 mg tablet form to be taken orally
Placebo to match LCZ696 50 mg, 100 mg, 200 mg tablet form to be taken orally

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline in N-terminal Pro-brain Natriuretic Peptide (NT-proBNP) at Week 12
Time Frame: Baseline, week 12

Time Frame
Mean Change From Baseline in Kansas City Cardiomyopathy Questionnaire (KCCQ) Clinical Summary Score (CSS) at Week 24
Time Frame: Baseline, Week 24
The KCCQ is a self-administered questionnaire that requires 4 to 6 minutes to complete. It contains 23 items, covering physical function, clinical symptoms, social function, self-efficacy and knowledge, and Quality of Life (QoL). The CSS is a combined score based upon the clinical symptoms and physical function domains of the questionnaire. Scores are transformed to a range of 0 - 100, in which higher scores reflect better health status.

Percentage of Patients With ≥ 5-points Deterioration in KCCQ Clinical Symptom Score(CSS) at Week 24
Time Frame: Baseline, Week 24
Percentage of patients with KCCQ CSS deterioration ≥ 5-points will be reported at Week 24. The KCCQ is a self-administered questionnaire that requires 4 to 6 minutes to complete. It contains 23 items, covering physical function, clinical symptoms, social function, self-efficacy and knowledge, and Quality of Life (QoL). The CSS is a combined score based upon the clinical symptoms and physical function domains of the questionnaire.

Percentage of Patients With ≥ 5-points Improvement in KCCQ Clinical Symptom Score(CSS) at Week 24
Time Frame: Baseline, Week 24
Percentage of patients with KCCQ CSS improvement ≥ 5-points will be reported at Week 24. The KCCQ is a self-administered questionnaire that requires 4 to 6 minutes to complete.

Baseline, Week 24
Change From Baseline in NYHA Functional Class at Week 24
Time Frame: Baseline, week 24

NYHA classification is a subjective physician's assessment of patient's functional capacity and symptomatic status and can change frequently over time.

Class I - No limitation of physical activity. Ordinary physical activity does not cause symptoms of HF Class II - Slight limitation of physical activity. Comfortable at rest, but ordinary physical activity results in symptoms of HF Class III - Marked limitation of physical activity. Comfortable at rest, but less than ordinary activity causes symptoms of HF Class IV - Unable to carry on any physical activity without symptoms of HF, or symptoms of HF at rest

The NYHA class change will be analyzed as a three category ordinal variable with levels: "improved", "unchanged", and "worsened", defined by at least one class improvement, no change, at least one class worsening, in NYHA class, respectively.

Baseline, week 24
