Naarden, the Netherlands and Miami, USA; February 28, 2024 – 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 with elevated low-density lipoprotein cholesterol (“LDL-C”), for whom existing therapies are not sufficiently effective or well-tolerated, today announced financial results for the fourth quarter and full year ended December 31, 2023 and provided a corporate update.

“2023 was a year of remarkable progress for NewAmsterdam, marked by consistent clinical execution and substantial corporate development. We reported multiple encouraging datasets and expanded our team with key hires, underscoring our commitment to revolutionizing patient outcomes, building a fully integrated company with the potential to deliver obicetrapib globally, if approved, and continue creating significant value for our shareholders,” said Michael Davidson, M.D., Chief Executive Officer of NewAmsterdam. “We enter 2024 in a position of strength, with multiple upcoming milestones and a healthy balance sheet to support our operations. In the near-term, we look forward to topline results from BROOKLYN and BROADWAY in the third and fourth quarters of 2024, respectively, which we expect will build on the promising datasets generated from our prior Phase 2 trials and support obicetrapib’s ability to positively impact key lipid and lipoprotein measurements associated with risk for cardiovascular disease.”

Dr. Davidson continued, “In addition, in the first quarter of this year, we anticipate completing enrollment in PREVAIL, our cardiovascular outcomes trial, and launching TANDEM, our fourth pivotal Phase 3 trial, which will evaluate a fixed-dose combination of obicetrapib and ezetimibe. As we advance our clinical program, we continue to invest strategically in our commercial organization to lay the foundation for obicetrapib’s successful global launch, pending necessary regulatory approvals. We believe we are on the precipice of delivering a transformative solution to improve outcomes for over 30 million patients impacted by cardiovascular disease in the U.S., and we eagerly anticipate sharing further progress and achievements in the upcoming year.”

2023 Highlights and Recent Progress

Clinical Development Updates:

NewAmsterdam is developing obicetrapib, an oral, low-dose and once-daily cholesteryl ester transfer protein (“CETP”) inhibitor, as the preferred LDL-C lowering therapy to be used in patients at risk of CVD for whom existing therapies are not sufficiently effective or well-tolerated. In 2023, NewAmsterdam reported positive, statistically significant and clinically meaningful data from two Phase 2 clinical trials of obicetrapib: the Phase 2 ROSE2 trial, which evaluated obicetrapib in combination with ezetimibe, and a Phase 2b dose-finding trial, which evaluated obicetrapib in Japanese patients. In total, the Company has completed six Phase 1 or 2 clinical trials and tested obicetrapib in over 800 patients. Statistically significant LDL-lowering was observed in each of the Company’s completed Phase 2 clinical trials, combined with a side effect profile similar to placebo.

The Company is currently conducting three pivotal Phase 3 clinical trials of obicetrapib: BROOKLYN, BROADWAY and PREVAIL. In addition, the Company plans to initiate a fourth Phase 3 trial, TANDEM, evaluating a fixed-dose combination (“FDC”) of obicetrapib and ezetimibe.

In 2023, NewAmsterdam reported positive initial data from a Phase 2a clinical trial evaluating obicetrapib in patients with early Alzheimer’s disease who carry at least one copy of the apolipoprotein E4 mutation. NewAmsterdam anticipates sharing the full results from this Phase 2a clinical trial in a forthcoming publication or in a presentation at a medical meeting.

About Obicetrapib

Obicetrapib 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 high-risk cardiovascular disease (“CVD”) patients. The Company began enrolling patients in BROADWAY in January 2022 and in BROOKLYN in July 2022 and completed 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 NewAmsterdam

NewAmsterdam 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.
