NAMSW NewAmsterdam Pharma Company NV

NewAmsterdam Pharma Company N.V. (Nasdaq: NAMS or “NewAmsterdam” or the “Company”), a late-stage, clinical biopharmaceutical company developing oral, non-statin medicines for patients at risk of cardiovascular disease (“CVD”) with elevated low-density lipoprotein cholesterol (“LDL-C”), for whom existing therapies are not sufficiently effective or well-tolerated, today announced that it will present additional data from the Phase 2 ROSE2 clinical trial at the 2024 American College of Cardiology Congress (“ACC”) in Atlanta, Georgia, being held April 6-8. ROSE2 evaluated obicetrapib in combination with ezetimibe as an adjunct to high-intensity statin therapy; full results from the trial were previously presented at the National Lipid Association Scientific Sessions in June 2023. At ACC, NewAmsterdam will share new data demonstrating obicetrapib and ezetimibe’s impact on small dense LDL-C, a robust predictor of residual risk of future cardiovascular events.

NewAmsterdam recently initiated TANDEM, a pivotal Phase 3 clinical trial to evaluate obicetrapib and ezetimibe FDC (‘fixed-dose combination”) in adult patients with Heterozygous Familial Hypercholesterolemia (“HeFH”) and/or Atherosclerotic Cardiovascular Disease (“ASCVD”) or multiple risk factors for ASCVD, whose LDL-C is not adequately controlled despite being on maximally tolerated lipid-modifying therapies.

Details of the presentation are as follows:

Presentation at the 2024 American College of Cardiology (ACC) Congress:Session Title: 1433: Prevention and Health Promotion: Lipids 12Session Date/Time: Sunday, April 7, 2024, 1:15 p.m. EDTSession Location: Hall B4-5, World Congress CenterPresentation Title: 211 - Synergistic Effect of Obicetrapib and Ezetimibe on Circulating LDL ParticlesLocation: Atlanta, Georgia, U.S.

About ObicetrapibObicetrapib is a novel, oral, low-dose CETP inhibitor that NewAmsterdam is developing to overcome the limitations of current LDL-lowering treatments. The Company believes that obicetrapib has the potential to be a once-daily oral CETP inhibitor for lowering LDL-C, if approved. In the Company’s Phase 2b ROSE trial, obicetrapib demonstrated a 51% lowering of LDL-C from baseline at a 10 mg dose level on top of high-intensity statins and, in the Company’s Phase 2 ROSE2 trial, the combination of a 10 mg dose of obicetrapib and a 10 mg dose of ezetimibe demonstrated a 63% lowering of LDL-C from baseline. In each of the Company’s Phase 2 trials, ROSE2, TULIP, ROSE, and OCEAN, evaluating obicetrapib as monotherapy or combination therapy, the Company observed statistically significant LDL-lowering combined with a side effect profile similar to that of placebo, including no increase in blood pressure or muscle related side effects. Obicetrapib has demonstrated strong tolerability in more than 800 patients with elevated lipid levels (“dyslipidemia”) in NewAmsterdam’s clinical trials to date. The Company is conducting two Phase 3 pivotal trials, BROADWAY and BROOKLYN, to evaluate obicetrapib as a monotherapy used as an adjunct to maximally tolerated lipid-lowering therapies to provide additional LDL-lowering for CVD patients and TANDEM, to evaluate obicetrapib and ezetimibe as a FDC. The Company began enrolling patients in BROADWAY in January 2022, in BROOKLYN in July 2022, and in TANDEM in March 2024; completing enrollment of BROOKLYN in April 2023 and BROADWAY in July 2023. The Company also commenced the Phase 3 PREVAIL cardiovascular outcomes trial in March 2022, which is designed to assess the potential of obicetrapib to reduce occurrences of major adverse cardiovascular events, including cardiovascular death, non-fatal myocardial infarction, non-fatal stroke and non-elective coronary revascularization.

About NewAmsterdamNewAmsterdam Pharma (Nasdaq: NAMS) is a late-stage biopharmaceutical company whose mission is to improve patient care in populations with metabolic diseases where currently approved therapies have not been adequate or well tolerated. We seek to fill a significant unmet need for a safe, well tolerated and convenient LDL-lowering therapy. In multiple phase 3 studies, NewAmsterdam is investigating obicetrapib, an oral, low-dose and once-daily CETP inhibitor, alone or as a fixed-dose combination with ezetimibe, as preferred LDL-C lowering therapies to be used as an adjunct to statin therapy for patients at risk of CVD with elevated LDL-C, for whom existing therapies are not sufficiently effective or well tolerated.
