Safety and Tolerability of Initiating LCZ696 in Heart Failure Patients

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to assess the safety and tolerability of initiating LCZ696 in heart failure patients with reduced ejection fraction (HF-rEF) using conservative (reaching target dose over 6 weeks) and condensed (reaching target dose over 3 weeks) up-titration regimens.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants Experiencing Hypotension, Renal Dysfunction, Hyperkalemia and Angioedema and by Renin-Angiotensin-Aldosterone System (RAAS) Stratum (High vs. Low) | Participants experiencing hypotension, renal dysfunction, hyperkalemia and angioedema and by Renin-Angiotensin-Aldosterone System (RAAS) stratum (high vs. low) High RAAS stratum Patients receiving > 160 mg of valsartan or > 10 mg total daily dose of enalapril, or equivalent doses of other ARBs/ACEIs, respectively, at screening Low RAAS stratum: Patients receiving ≤ 160 mg of valsartan or ≤ 10 mg total daily dose of enalapril, or equivalent doses of other ARBs/ACEIs, respectively, at screening. This stratum also included patients who were not on an ACEI or an ARB 4 weeks prior to screening (i.e., ACEI/ARB-naïve patients) | 12 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants Who Achieved Treatment Success Over the 12 Weeks and by Renin-Angiotensin-Aldosterone System (RAAS) Stratum (High vs. Low) | Treatment success was defined as the number of participants who achieved and maintained LCZ696 200 mg bid without any dose interruption or down-titration over 12 weeks and by Renin-Angiotensin-Aldosterone System (RAAS) stratum (high vs. low) High RAAS stratum Patients receiving > 160 mg of valsartan or > 10 mg total daily dose of enalapril, or equivalent doses of other ARBs/ACEIs, respectively, at screening Low RAAS stratum: Patients receiving ≤ 160 mg of valsartan or ≤ 10 mg total daily dose of enalapril, or equivalent doses of other ARBs/ACEIs, respectively, at screening. This stratum also included patients who were not on an ACEI or an ARB 4 weeks prior to screening (i.e., ACEI/ARB-naïve patients) | 12 weeks | 
| Number of Participants Who Tolerated Study Medication for at Least the Last Two Weeks of the Study and by Renin-Angiotensin-Aldosterone System (RAAS) Stratum (High vs. Low). | Tolerability was assessed as the number of participants who achieved LCZ696 200 mg bid and maintained this dose for at least 2 weeks before study completion, regardless of previous dose interruption or down-titration and by Renin-Angiotensin-Aldosterone System (RAAS) stratum (high vs. low) High RAAS stratum Patients receiving > 160 mg of valsartan or > 10 mg total daily dose of enalapril, or equivalent doses of other ARBs/ACEIs, respectively, at screening Low RAAS stratum: Patients receiving ≤ 160 mg of valsartan or ≤ 10 mg total daily dose of enalapril, or equivalent doses of other ARBs/ACEIs, respectively, at screening. This stratum also included patients who were not on an ACEI or an ARB 4 weeks prior to screening (i.e., ACEI/ARB-naïve patients) | 12 weeks |
