This is obviously a huge blow to Novartis, as they were hoping that Entresto would be as effective for patients with HFpEF as it is for those with HFrEF. Now with the PARAGON-HF topline data, it is highly unlikely that regulators would accept an application for a label update. 

This leaves the door open for various competitors to obtain first approval for HFpEF, with Lilly/Boehringer’s Jardiance, which received Fast Track designation last month, likely the furthest ahead at this point. Depending on the full results of the PARAGON-HF trial, there is the possibility that physicians will use Entresto off-label for HFpEF until something is officially approved. 

Novartis is running a smaller trial for Entresto in HFpEF (PARALLAX) that has an expected primary completion of Dec 2019.
