An Open-label Extension Study Evaluating Safety and Tolerability of LCZ696 in Subjects Who Completed PARAGON-HF in Japan.

Study Overview
=================
Brief Summary
-----------------
This study evaluated the safety and tolerability of LCZ696 treatment in Japanese heart failure patients (NYHA Class II-IV) with preserved ejection fraction after CLCZ696D2301 (PARAGON-HF).

Detailed Description
-----------------
This study was an open-label extension study following the PARAGON-HF. Patients who have completed the PARAGON-HF were eligible to participate. During the study, open-label LCZ696 was taken in addition to background treatments of comorbidities. All subjects were treated with LCZ696 (sacubitril/valsartan) at maximally tolerated dosed with a target dose of 200 mg b.i.d (twice a day). The subject were to continue to receive LCZ696 until it became commercially available, or for a period up to 24 months from the first patient enrolled in this study whichever came first. However, this study was terminated early based on the pre-defined early termination criteria of the primary endpoint of PARAGONHF was not met in the protocol.

Official Title

Intervention / Treatment
-----------------
* Drug: LCZ696


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Signed informed consent must be obtained before any assessment is performed. Patients who have completed LCZ696D2301 and are able to be safely enrolled into this study as judged by the investigator. Exclusion Criteria: Patients who discontinued study drug treatment during LCZ696D2301 due to an event or intercurrent illness. Eligibility can be re-considered if the event has resolved and no longer represents a risk to the patient and the patient can safely tolerate the administration of LCZ696 per the investigator's assessment. Any medical condition that in the opinion of the investigator is likely to prevent the patient from safely tolerating LCZ696 or complying with the requirements of the study. Patients who have experience of angioedema event(s) which occurred and reported by the investigator during LCZ696D2301. Pregnant or nursing (lactating) women. Women of childbearing potential unless they are using highly effective methods of contraception. Other protocol-defined inclusion/exclusion may apply.
