Etzer Darout's questions to Novartis AG (NVS) leadership • Q4 2024
Question
Etzer Darout asked for additional commentary on the delay of the HORIZON Phase III trial readout for pelacarsen, inquiring about the potential drivers of the event rate dynamics.
Answer
CEO Vasant Narasimhan clarified that the delay is due to event rate modeling on the blinded data, not an interim analysis. He explained that cardiovascular outcome studies have been trending toward lower event rates over time, and it's preferable to ensure the study is adequately powered by waiting for the target number of events, which is now expected in early 2026. He remains confident in the drug's mechanism.
