FRONTIER2 data presented at ISTH 2024 showed that up to 95% of people, who had no prior prophylaxis treatment, experienced zero treated bleeds while on Mim8
Novo Nordisk announced results from the phase 3 FRONTIER2 trial of 254 adults and adolescents aged 12 years and over with haemophilia A, with and without inhibitors. The trial assessed both once-weekly and once-monthly prophylactic treatment (regular treatment to prevent prolonged and spontaneous bleeding) with the investigational treatment Mim8. The data were presented at the International Society of Thrombosis and Haemostasis Annual Congress (ISTH 2024) in Bangkok, Thailand.
In the trial population with no prior prophylaxis treatment:
In the trial population with prior coagulation factor prophylaxis:
“Despite treatment advances, there are still many unmet needs for people living with haemophilia A,” said FRONTIER2 lead investigator Dr Maria Elisa Mancuso, Senior Consultant in Haematology, Centre for Thrombosis and Haemorrhagic Diseases, IRCCS Humanitas Research Hospital, Milan, Italy. “The FRONTIER2 data demonstrated superiority of Mim8 prophylaxis over both on demand treatment and prior clotting factor prophylaxis with respect to the number of treated bleeding episodes in people living with haemophilia A, regardless of their inhibitor status. It is also encouraging to see that in some subgroups in the study, up to 95% of people treated with Mim8 experienced zero bleeds.”
Mim8 is a next-generation Factor VIIIa (FVIIIa) mimetic bispecific antibody designed with the potential to deliver sustained haemostasis. It is currently in development for once-weekly or once-monthly prophylaxis treatment for people living with haemophilia A, with and without inhibitors. Administered subcutaneously, Mim8 bridges Factor IXa/X (FIXa/FX), thereby replacing missing FVIII. This restores the body’s thrombin generation capacity, helping blood to clot.1 In this trial, Mim8 was well-tolerated, and no safety concerns (thromboembolic events or related serious adverse events) were observed, in line with previous findings.
“The FRONTIER2 efficacy and safety data is very encouraging,” said Martin Holst Lange, Executive Vice President of Development at Novo Nordisk. “With Mim8, we have the potential of offering a substantial proportion of patients the prospect of zero bleeds and convenient dosing flexibility to fit their lifestyles and needs. We look forward to discussing these data with regulatory authorities.”
Contingent on regulatory interactions, Novo Nordisk aims to submit Mim8 for the first regulatory approval towards the end of 2024. Data from the ongoing phase 3 FRONTIER programme will continue to be disclosed at upcoming congresses and in publications in 2024 and 2025.
