2022-06-03 Novo Nordisk A/S Results Novo Nordisk achieves primary objectives of ONWARDS 1 and 6 trials with once-weekly insulin icodec demonstrating superior reduction in HbA1c vs insulin glargine U100 in ONWARDS 1 novonordisk.com ↗
From an overall baseline HbA1c of 8.5% once-weekly insulin icodec achieved a superior reduction in estimated HbA1c of -1.55% compared to -1.35% for insulin glargine (estimated treatment difference: -0.19%).
2017-05-27 Novo Nordisk A/S Results Novo Nordisk submits application in the US for including data from the DEVOTE trial in the Tresiba® label novonordisk.com ↗
In the DEVOTE trial, the primary endpoint was achieved by demonstrating non-inferiority of major adverse cardiovascular events (MACE) with Tresiba® compared to insulin glargine U100.
2016-11-29 Novo Nordisk A/S Results Novo Nordisk A/S: Tresiba® demonstrates a safe cardiovascular profile and reduces the risk of severe hypoglycaemia compared to insulin glargine U100 in the DEVOTE trial novonordisk.com ↗

2016-11-10 Novo Nordisk A/S Results Novo Nordisk submits application in the EU for including data from the two SWITCH trials in Tresiba® label novonordisk.com ↗
During the study's maintenance period, people treated with Tresiba® on average had 11% fewer episodes of overall symptomatic blood glucose confirmed hypoglycaemia, 36% fewer episodes of nocturnal blood glucose confirmed symptomatic hypoglycaemia and 35% fewer episodes of severe hypoglycaemia.
2016-02-23 Novo Nordisk A/S Results Tresiba® demonstrates significantly lower rate of hypoglycaemia than insulin glargine U100 in blinded phase 3b trial in people with type 1 diabetes novonordisk.com ↗
The observed rate was 2,201 events per 100 patient years exposed to Tresiba® and 2,463 events per 100 patient years exposed to insulin glargine during the maintenance period, corresponding to a statistically significant reduction of 11%.
