Description of Tolerability of LCZ696 (Sacubitril / Valsartan) in Heart Failure With Reduced Ejection Fraction (HFrEF) Treated in Real Life Setting

Phase 4

Completed

Conditions: Hearth Failure With Reduced Ejection Fraction (HFrEF)

Interventions: Drug: LCZ696 (sacubitril/valsartan)

Registration Number: NCT02690974

Lead Sponsor: Novartis Pharmaceuticals

Brief Summary: The primary purpose of the study was to describe the tolerability of treatment with the optimal dose of LCZ696 (97 mg sacubitril / 103 mg valsartan bid), over six (6) months, in patients with heart failure with reduced ejection fraction (HFrEF) in Canada.

The study was also to describe the overall tolerability, effectiveness and safety of LCZ696 for the management of HFrEF over 12 months of treatment, as well as describe the patterns of LCZ696 up and down dose titrations occurring during the management of patients with HFrEF.

Arm && Interventions

Group	Intervention	Description
LCZ696 (sacubitril / valsartan)	LCZ696 (sacubitril/valsartan)	All patients were initiated on either LCZ696 at 24 mg sacubitril / 26 mg valsartan or LCZ696 at 49 mg sacubitril / 51 mg valsartan bid for 2-4 weeks and were up-titrated to the next higher dose for another 2 - 4 weeks as applicable.

Primary Outcome Measures

Name	Time	Method
Percentage of Participants on LCZ696 200 mg Bid at Month 6	Month 6	The tolerability of LCZ696 was defined as the percentage of patients on LCZ696 at the dose of 97 mg sacubitril / 103 mg valsartan twice daily (bid) who did not experience down titration or treatment discontinuation because of adverse events while on this dose at month 6. Only descriptive analysis done.

Secondary Outcome Measures

Name	Time	Method
Percentage of Participants on LCZ696 200 mg Bid at Month 12	Month 12	The tolerability of LCZ696 was defined as the percentage of patients on LCZ696 at the dose of 97 mg sacubitril / 103 mg valsartan twice daily (bid) who did not experience down titration or treatment discontinuation because of adverse events while on this dose at month 12. Only descriptive analysis done.
Percentage of Participants Requiring Down-titration From LCZ696 200 mg	Month 12	The impact of the titration scheme on the tolerability of patients maintained on LCZ696 97 mg sacubitril / 103 mg valsartan bid was defined as the percentage of patients on LCZ696 200mg requiring down-titration. Only descriptive analysis done.
Percentage of Participants With Down-titration Changes From LCZ696 200 mg During 12 Months of Treatment	Month 12	The impact of the titration scheme on the tolerability of patients maintained on LCZ696 97 mg sacubitril / 103 mg valsartan bid was defined as the number of down-titration during the 12 months treatment period. Dow-titration schemes considered for the analysis are 200 mg to 100 mg; 100 mg to 50 mg; and 50 mg to 0 mg (i.e. treatment discontinuation). The down-titration scheme of 50mg to 0 mg was taken in account in this analysis to ensure to reflect all actual changes in dose. Only descriptive analysis done.
Change From Baseline in the Six Minute Walk Test (6MWT) at Month 6 and Month 12	Baseline, Month 6 and Month 12	The impact of LCZ696 on functional exercise capacity was measured by the Six Minute Walk Test at 6 and 12 months. The 6MWT measures the distance an individual is able to walf over a total of six minutes on a hard, flat surface. The goal is for the individual to walk as far as possible in six minutes. The individual is able to self-pace and rest as needed as they traverse back and forth along a marked walkway. Only descriptive analysis done.
Time to Each Up-titration to LCZ696 100 mg and LCZ696 200 mg	Baseline, Week 2, Week 4, Month 3, Month 6 and Month 12	To describe the time of up-titration for each dose (24 mg sacubitril / 26 mg valsartan bid and 49 mg sacubitril / 51 mg valsartan bid) of LCZ696. Only descriptive analysis done.
Median Time to Reach LCZ696 200 mg	Baseline, Week 2, Week 4, Month 3, Month 6 and Month 12	To describe the time of up-titration for each dose (24 mg sacubitril / 26 mg valsartan bid and 49 mg sacubitril / 51 mg valsartan bid) of LCZ696. Only descriptive analysis done.
Percentage of Participants on Guideline Recommended Dose of Beta-blockers and MRAs Over Time	Baseline, Month 6 and Month 12	To describe the adherence to guideline recommended dosing of beta-blockers and MRAs at 6 and 12 months of treatment of LCZ696. Only descriptive analysis done.
