– Marketing Authorization Applications for obicetrapib and FDC of obicetrapib plus ezetimibe accepted for review by European Medicines Agency – – BROOKLYN and BROADWAY pooled MACE analysis published in the Journal of the American College of Cardiology, while the BROADWAY pre-specified Alzheimer’s substudy was published in the Journal of Prevention of Alzheimer’s Disease – – $756.0 million in cash, cash equivalents and marketable securities at September 30, 2025 – NAARDEN, the Netherlands and MIAMI, Nov. 05, 2025 (GLOBE NEWSWIRE) — 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 financial results for the quarter ended September 30, 2025 and provided a corporate update. “We remain acutely focused on our mission to deliver obicetrapib, as a novel, well-tolerated, and conveniently administered therapy for millions of patients with cardiometabolic disease who continue to struggle to reach their LDL-C goals,” said Michael Davidson, M.D., Chief Executive Officer of NewAmsterdam. “In the third quarter, we achieved a significant regulatory milestone with the European Medicines Agency’s (“EMA”) acceptance for review of the marketing authorization applications (“MAAs”), by our partner Menarini, for both obicetrapib monotherapy and the fixed-dose combination (“FDC”) with ezetimibe. These submissions, supported by data from our pivotal BROADWAY, BROOKLYN and TANDEM trials, represent an important step toward bringing obicetrapib to patients across Europe.” “In parallel, we continue to advance our broader clinical development strategy, including PREVAIL, our ongoing cardiovascular outcomes trial (“CVOT”), and REMBRANDT, our Phase 3 imaging trial,” continued Dr. Davidson. “We are also making meaningful progress building our global infrastructure to support the potential launch of obicetrapib, if approved. As we engage with the investment and medical communities through upcoming conference and medical meetings, we look forward to sharing new pooled efficacy and safety data and to further highlighting our strategic vision for obicetrapib as a differentiated therapy in a large and growing market.” Clinical Development Updates NewAmsterdam is developing obicetrapib, an oral, low-dose and once-daily investigational 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 July 2025, NewAmsterdam announced additional results from the prespecified Alzheimer’s disease (“AD”) biomarker analysis in the Phase 3 BROADWAY trial, presented at the 2025 Alzheimer’s Association International Conference (“AAIC”), which NewAmsterdam believes further support the potential of obicetrapib to modify key biomarkers of AD pathology over a 12-month period in patients with atherosclerotic cardiovascular disease (“ASCVD”). In ApoE4/E4 carriers, the highest risk category for Alzheimer’s disease, obicetrapib was observed to reduce p-tau217 levels by 20.5%, over 12 months, compared to placebo (p=0.010, n=29).In October 2025, the data was published in the Journal of Prevention of Alzheimer’s Disease. In August 2025, NewAmsterdam presented pooled efficacy and safety data from its pivotal Phase 3 BROADWAY and BROOKLYN trials at the European Society of Cardiology Congress (“ESC”) 2025, along with the simultaneous publication in the Journal of the American College of Cardiology, highlighting obicetrapib’s performance across diverse lipid-lowering backgrounds observed in these trials. The presentation and publication underscore the Company’s continued momentum in advancing obicetrapib as a differentiated oral therapy for patients with elevated LDL-C.In November 2025, NewAmsterdam expects to present additional data at the American Heart Association’s Scientific Sessions 2025, highlighting obicetrapib’s impact on LDL particles observed in BROADWAY and BROOKLYN. Upcoming Milestones and Ongoing Trials: Following the successful completion and positive topline results of the Phase 3 BROADWAY, TANDEM, and BROOKLYN trials, NewAmsterdam plans to announce additional data from these trials relating to obicetrapib and the FDC of obicetrapib plus ezetimibe. The following Phase 3 trials are currently ongoing: PREVAIL Phase 3 trial: PREVAIL is a CVOT evaluating obicetrapib in patients with a history of ASCVD, whose LDL-C is not adequately controlled despite being on maximally tolerated lipid-lowering therapy. NewAmsterdam completed enrollment of over 9,500 patients in April 2024.REMBRANDT Phase 3 trial: The trial will utilize coronary computed tomography angiography imaging to evaluate the effect of obicetrapib plus ezetimibe FDC on coronary plaque. The placebo-controlled, double-blind, randomized, Phase 3 trial is being conducted in adult participants with high-risk ASCVD with evidence of coronary plaque who are not adequately controlled by their maximally tolerated lipid-modifying therapy, to assess the impact of the obicetrapib 10 mg plus ezetimibe 10 mg FDC daily on coronary plaque and inflammation characteristics. The trial is expected to enroll 300 patients. NewAmsterdam also plans to initiate the RUBENS Phase 3 clinical trial to evaluate obicetrapib in combination with ezetimibe in patients with type 2 diabetes or metabolic syndrome that require additional lowering of LDL-C despite treatment with available therapy. The RUBENS trial is expected to initiate in the fourth quarter of 2025. Corporate Updates In August 2025, the EMA accepted for review the MAAs for obicetrapib 10 mg monotherapy and the FDC of 10 mg obicetrapib plus 10 mg ezetimibe for the treatment of primary hypercholesterolemia, including heterozygous familial and non-familial or mixed dyslipidemia. The EMA’s validation of the submissions, made by NewAmsterdam’s partner, A. Menarini International Licensing S.A. (“Menarini”), represents a key regulatory milestone. The submissions are supported by data from the BROADWAY, BROOKLYN, and TANDEM pivotal Phase 3 trials. Third Quarter Financial Results Cash Position: As of September 30, 2025, NewAmsterdam recorded cash, cash equivalents and marketable securities of $756.0 million, compared to $834.2 million as of December 31, 2024. The decrease was primarily driven by ongoing operating expenditures.Revenue: NewAmsterdam recognized $0.3 million in revenue for the quarter ended September 30, 2025, compared to $29.1 million in the same period in 2024. The decrease was primarily attributable to the recognition of $27.3 million of revenue from a license agreement with Menarini related to a clinical development milestone which was earned in the quarter ended September 30, 2024 while there were no clinical milestones earned in the quarter ended September 30, 2025.Research and Development (“R&D”) Expenses: R&D expenses were $31.0 million in the quarter ended September 30, 2025, compared to $35.7 million for the same period in 2024. This decrease was primarily due to a decrease in clinical expenses and manufacturing expenses, partially offset by an increase in personnel expenses, including share-based compensation and non-clinical expenses related to pipeline expansion and product lifecycle management. Share-based compensation expenses included with R&D expenses totaled $5.0 million in the quarter ended September 30, 2025, compared to $3.0 million for the same period in 2024.Selling, General and Administrative (“SG&A”) Expenses: SG&A expenses were $24.5 million in the quarter ended September 30, 2025, compared to $18.4 million for the same period in 2024. This increase was primarily due to an increase in personnel expenses, including share-based compensation. Share-based compensation expenses included with SG&A expenses totaled $10.0 million in the quarter ended September 30, 2025, compared to $5.0 million for the same period in 2024.Net loss: Net loss for the quarter ended September 30, 2025, was $72.0 million, compared to net loss of $16.6 million for the same period in 2024. The individual components of the change are described above in addition to non-cash losses related to changes in the fair value of our derivative liabilities. About Obicetrapib Obicetrapib is a novel, oral, low-dose CETP inhibitor that NewAmsterdam is developing to overcome the limitations of current LDL-lowering treatments. In each of the Company’s Phase 2 trials, ROSE2, TULIP, ROSE, and OCEAN, as well as the Company’s Phase 3 BROOKLYN, BROADWAY and TANDEM trials, 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. The Company commenced the Phase 3 PREVAIL cardiovascular outcomes trial in March 2022, which is designed to assess the potential of obicetrapib to reduce occurrences of MACE. The Company completed enrollment of PREVAIL in April 2024 and randomized over 9,500 patients. Commercialization rights of obicetrapib in Europe, either as a monotherapy or as part of a fixed-dose combination with ezetimibe, have been exclusively granted to the Menarini Group, an Italy-based, leading international pharmaceutical and diagnostics company. About Cardiovascular Disease Cardiovascular disease remains the leading cause of death globally, despite the availability of lipid-lowering therapies (“LLTs”). By 2050 more than 184 million U.S. adults are expected to be affected by CVD and hypertension, including 27 million with coronary heart disease and 19 million with stroke. In the United States from 2019 through 2022, CVD age-adjusted mortality rates increased by 9%, reversing the trend observed since 2010 and undoing nearly a decade of progress. Despite the availability of high-intensity statins and non-statin LLTs, LDL-C target level attainment remains low, contributing to residual cardiovascular risk, and underscoring a significant clinical need for improved therapeutic regimens. Even with 269 million LLT prescriptions written over the last 12 months, 30 million under-treated US adults are not at their risk-based LDL-C goal, of which 13 million have ASCVD. Less than 1 in 4 patients with ASCVD achieve an LDL-C goal of less than 70 mg/dL and only 10% of very high risk ASCVD patients achieve the goal below 55 mg/dL. In addition to the 30 million under-treated U.S. adults, there are 10 million patients diagnosed with elevated LDL-C who are not taking any LLTs including statins. Beyond LDL-C, additional factors are at play, such as lifestyle choices, tobacco use, and obesity, as well as inflammation, thrombosis, triglyceride levels, elevated Lp(a) levels, and type 2 diabetes. Alzheimer’s Analysis In BROADWAY, a pre-specified analysis was designed to assess plasma biomarkers of Alzheimer’s disease (“AD”) in patients enrolled in the BROADWAY trial and evaluated the effects of longer duration of therapy (12 months) with a prespecified ApoE population, based on phenotypic analysis. The analysis included 1,535 patients, including 367 ApoE4 carriers (ApoE3/E4 or ApoE4/E4), whose ApoE status was able to be determined. Because this analysis was based on a subset of patients from BROADWAY (which was designed to evaluate LDL-C reductions in an ASCVD and/or HeFH population), the AD analysis was not controlled for baseline differences between the treatment and placebo populations, but statistical analyses were adjusted for baseline biomarker values and age. The absolute and percent change over 12 months in p-tau217, a key biomarker of AD pathology, was measured among patients with baseline and end of study datapoints above the lower limit of quantitation. Additional outcome measures included NFL, GFAP, p-tau181, and Aβ42/40 ratio absolute and percent change over 12 months. NewAmsterdam observed statistically significant lower absolute changes in p-tau217 compared to placebo over 12 months in both the full analysis set (p=0.025; n= 1,535) and in ApoE4 carriers (p=0.022; n=367) as well as favorable trends in the other AD biomarkers. Although a safety analysis was not performed in the AD analysis population, in BROADWAY obicetrapib was observed to be well-tolerated, with safety results comparable to placebo. About NewAmsterdam NewAmsterdam Pharma (Nasdaq: NAMS) is a late-stage clinical 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 trials, NewAmsterdam is investigating obicetrapib, an oral, low-dose and once-daily CETP inhibitor, alone or as a fixed-dose combination with ezetimibe, as 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.
