About NewAmsterdam Pharma

NewAmsterdam Pharma Company B.V. (“NewAmsterdam Pharma”) is a private clinical-stage biopharmaceutical company whose mission is to improve patient care in populations with metabolic diseases where traditional therapies have not been sufficiently successful or well-tolerated. NewAmsterdam Pharma is investigating obicetrapib, a next-generation oral, low-dose and once-daily CETP inhibitor, as the preferred LDL-C-lowering therapy for high-risk cardiovascular disease (“CVD”) patients. Results from NewAmsterdam Pharma’s ROSE Phase 2b trial (presented at AHA Scientific Sessions in 2021) included observations that patients receiving obicetrapib 10mg experienced reduced LDL-C by 51% versus baseline in patients on statin therapy (vs. a 7% reduction in the placebo arm). Based in the Netherlands, NewAmsterdam Pharma was founded in 2019 by the venture capital firm Forbion and John Kastelein, Chief Scientific Officer of NewAmsterdam Pharma, and closed a $196 million (€160 million) Series A financing in January 2021 led by Forbion, Morningside Ventures and Ascendant BioCapital. In June 2022, NewAmsterdam Pharma entered into an exclusive licensing agreement with the Menarini Group for the

commercialization of obicetrapib in Europe, while retaining all rights to commercialize obicetrapib, if approved, in the rest of the world, as well as rights to develop certain forms of obicetrapib for other diseases such as Alzheimer’s disease. For more information, please visit:
