NAARDEN, The Netherlands and MIAMI, Dec. 10, 2024 (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 positive topline data from the Company’s Phase 3 BROADWAY clinical trial (NCT05142722) evaluating obicetrapib in adult patients with established atherosclerotic cardiovascular disease (“ASCVD”) and/or heterozygous familial hypercholesterolemia (“HeFH”), whose LDL-C is not adequately controlled, despite being on maximally tolerated lipid-lowering therapy.

“We initiated four Phase 3 trials with obicetrapib in December 2021, with the hope that obicetrapib would become the therapeutic option of choice to add to statin therapy to further reduce cardiovascular (“CV”) risk,” said Michael Davidson, M.D., Chief Executive Officer of NewAmsterdam. “Our aspiration was that our Phase 3 trials would not only confirm the efficacy and tolerability observed in Phase 2 but also clearly demonstrate a safety and clinical profile that would differentiate obicetrapib from other LDL-C lowering therapies. We are proud to have observed in our Phase 3 trials to date not only durable LDL-C reduction in both the monotherapy obicetrapib group and the obicetrapib combination with ezetimibe group, but also a safety and tolerability profile that exceeded our expectations. We have observed obicetrapib, an oral, once-a-day, low-dose tablet, to be clinically differentiated from other lipid lowering therapies by lowering Lp(a) and small LDL-particles as well as potentially improving glycemic measures that are linked to high CV risk. Although exploratory at this point, the difference in major adverse cardiovascular events (“MACE”) at one year in BROADWAY supports our belief that obicetrapib could provide greater than expected CV risk reductions through mechanisms beyond LDL-C lowering. In 2025, we look forward to presenting additional BROADWAY and TANDEM data at upcoming scientific sessions and meeting with regulatory authorities to discuss filings for this important therapy to address the global unmet need for effective LDL-C lowering therapies.”

The primary endpoint was the least-squares mean of the percent change in LDL-C from baseline to day 84 for obicetrapib 10 mg compared to placebo, using imputation for missing data. The primary endpoint was achieved with statistical significance with an LDL-C reduction of 33% (p<0.0001).

LDL-C percentage change at day 84:

As part of the safety analysis, the trial adjudicated MACE, including death, non-fatal myocardial infarction, non-fatal stroke and coronary revascularization. In addition, a 21% reduction in MACE favoring obicetrapib was observed.

“I have provided leadership to cardiovascular drug development since the early statin days and was thrilled to see a safety profile as clean as obicetrapib, which has been comparable to placebo. Having lived and witnessed the accumulation of efficacy and safety data for obicetrapib from early Phase 1 through Phase 3, this moment is an exciting milestone,” said John Kastelein, M.D., Ph.D., FESC, Chief Scientific Officer of NewAmsterdam. “The unexpected magnitude of difference in MACE and early separation in the Kaplan-Meier curves that we observed may indicate obicetrapib’s potential benefit above LDL-C lowering alone. MACE risk is multifaceted and obicetrapib has shown consistent benefit in our clinical trials across a variety of drivers but ultimately, getting patients’ LDL-C to target is what I care about. I am optimistic that obicetrapib monotherapy and in combination with ezetimibe each could help most patients reach these goals, if approved.”

The observed changes in other biomarkers, including high-density lipoprotein cholesterol (“HDL-C”), non-HDL-C, lipoprotein(a) (“Lp(a)”), apolipoprotein B (“ApoB”), and Apolipoprotein A1 (ApoA1) were consistent with data reported in the Company’s prior clinical trials.

As part of the safety analysis, key adverse events (“AE”) of special interests were monitored. Among these AEs, glycemic control and renal function were monitored and each of the events favored obicetrapib. Overall, obicetrapib was also observed to be well-tolerated, with safety results, including blood pressure, comparable to placebo. The treatment discontinuation rate for the obicetrapib arm was 11.1% versus 12.4% for placebo. The incidence of treatment-emergent adverse events (“TEAEs”), trial-drug related TEAEs, and treatment-emergent serious adverse events (“TESAEs”) are summarized in the table below.

“Despite the widespread availability of lipid-lowering therapies, patients are still struggling to achieve target LDL-C levels and CVD-related death rates continue to rise,” said Stephen Nicholls, M.B.B.S., Ph.D., Director, Monash Victorian Heart Institute and Professor of Cardiology, Monash University. “The BROADWAY clinical trial highlights the transformative potential of obicetrapib — a powerful, well-tolerated, and convenient treatment option for millions with dyslipidemia, if approved, could help them reach their LDL-C goals and significantly reduce the risk of life-threatening cardiovascular events.”

NewAmsterdam plans to present additional results from BROADWAY at an upcoming medical conference and to publish the data in a major medical journal.

Design of the Pivotal Phase 3 BROADWAY Clinical Trial

The 52-week, global, pivotal, Phase 3, randomized, double-blind, placebo-controlled multicenter trial evaluated the efficacy and safety of 10 mg obicetrapib compared to placebo as an adjunct to maximally tolerated lipid-lowering therapies in patients with ASCVD and/or HeFH whose LDL-C is not adequately controlled. The trial was conducted at sites in North America, Europe, Asia and Australia. A total of 2,530 patients were randomized 2:1 to receive 10 mg obicetrapib or placebo dosed as a once-daily oral treatment, with or without food for 52 weeks. The mean baseline LDL-C for enrolled patients in the obicetrapib arm was approximately 100 mg/dL despite high intensity statin use reported by nearly 70% of patients during screening. Females comprised approximately 34% of the trial population and the median age of participants at baseline was 65 years.

The primary endpoint was LS mean percent change from baseline in LDL-C of obicetrapib 10 mg compared to placebo after 84 days which showed a reduction of 33% with imputation. Secondary endpoints also included percent changes from baseline of obicetrapib 10 mg compared to placebo in ApoB, Lp(a), ApoA1, HDL-C, non-HDL-C, total cholesterol, and triglycerides at day 84, and on LDL-C levels at days 180 and 365 (mean -34% and imputed LS mean of -24%, respectively with p<0.0001). Other exploratory outcome measures included time from randomization until the first confirmed occurrence of MACE in the obicetrapib arm compared to placebo. The trial also evaluated the safety and tolerability profile of obicetrapib.

About NewAmsterdam’s Global Pivotal Phase 3 Program

NewAmsterdam’s global, pivotal Phase 3 clinical development program consists of four trials in over 12,250 patients, three for obicetrapib monotherapy and one for a fixed-dose combination (“FDC”) of obicetrapib and ezetimibe:

• BROOKLYN evaluated obicetrapib in patients with HeFH, whose LDL-C is not adequately controlled despite being on maximally tolerated lipid-lowering therapy. NewAmsterdam reported topline data in the third quarter of 2024 and presented additional data at the American Heart Association Scientific Sessions 2024 in November.
• TANDEM evaluated obicetrapib as part of a FDC tablet with ezetimibe, a non-statin oral LDL-lowering therapy, in patients with established atherosclerotic cardiovascular disease (“ASCVD”) or multiple risk factors for ASCVD and/or HeFH, whose LDL-C is not adequately controlled despite being on maximally tolerated lipid-lowering therapy. NewAmsterdam reported topline data in November 2024.
• BROADWAY evaluated obicetrapib in adult patients with established ASCVD and/or HeFH, whose LDL-C is not adequately controlled despite being on maximally tolerated lipid-lowering therapy. NewAmsterdam completed enrollment of over 2,500 patients in July 2023 and reported topline data in the fourth quarter of 2024.
• PREVAIL is a cardiovascular outcomes trial 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.

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 is currently conducting 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. NewAmsterdam 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, for cardiovascular diseases have been exclusively granted to the Menarini Group, an Italy-based, leading international pharmaceutical and diagnostics company.

About Cardiovascular Disease

Cardiovascular disease (CVD) remains the leading cause of death globally, despite the availability of lipid-lowering therapies (LLTs). By 2050 more than 184 million US adults are expected to be affected by CVD and hypertension, including 27 million with coronary heart disease and 19 million with stroke. In the US from 2019 through 2022, CVD age-adjusted mortality rates increased 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, low-density lipoprotein cholesterol (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 70mg/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 US 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.

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 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.
