NAARDEN, the Netherlands and MIAMI, Nov. 18, 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 additional results from the Company’s Phase 3 BROOKLYN clinical trial (NCT05425745) evaluating obicetrapib in adult patients with heterozygous familial hypercholesterolemia (“HeFH”), whose LDL-C is not adequately controlled, despite being on maximally tolerated lipid-lowering therapy. The data were presented today in an oral late-breaker presentation at the American Heart Association (AHA) Scientific Sessions.

“We believe the additional data presented today underscore obicetrapib’s potential to significantly reduce not only LDL-C but also Lp(a), LDL particles, both total and small, along with several other biomarkers in HeFH patients when compared to treatment with placebo. Within the HeFH patient community, it is common for patients to be on multiple lipid-lowering therapies, and given the efficacy and safety profile observed to date, we believe obicetrapib has the potential, if approved, to provide physicians with a new tool to address unmet need in these patients,” said Stephen Nicholls, M.B.B.S., Ph.D., Director, Monash Victorian Heart Institute and Professor of Cardiology, Monash University.

“Despite the availability of lipid lowering therapies, CVD risk remains high and many people suffering from HeFH fail to meet their target cholesterol levels. We believe these additional results from the BROOKLYN pivotal trial further highlight obicetrapib’s potential to meaningfully reduce LDL-C, while also significantly improving additional CVD risk parameters including Lp(a), non- HDL-C, ApoB, and HDL-C,” said Michael Davidson, M.D., Chief Executive Officer of NewAmsterdam. “Together with the supportive data generated to date, these results reinforce our belief that, if approved, obicetrapib has the potential to meaningfully improve treatment for CVD patients worldwide. We look forward to building on these results with topline data from our TANDEM and BROADWAY studies expected in the fourth quarter of 2024.”

Phase 3 BROOKLYN Trial Results
The BROOKLYN trial met its primary endpoint, achieving an LS mean reduction of 36.3% (p < 0.0001) compared to placebo at day 84, which was sustained at day 365 with an LS mean LDL-C reduction of 41.5% (p < 0.0001). Secondary efficacy endpoints, including lipoprotein(a) (“Lp(a)”), which was 45.9% (p<0.0001) compared to placebo at day 84 and 54.3% (p=0.16) at day 365, apolipoprotein B (“ApoB”), high-density lipoprotein cholesterol (“HDL-C”) and non-HDL-C met statistical significance and results were consistent with data reported from NewAmsterdam’s prior clinical trials. The p-value for the LS mean for all secondary endpoints compared to placebo was <0.0001 following 84 days of treatment with obicetrapib.

“We are very encouraged by these additional results from BROOKLYN, where we observed obicetrapib’s lipid- and lipoprotein-lowering capabilities in a difficult to treat patient population that, despite being on multiple lipid-lowering therapies, still has elevated LDL-C,” said John Kastelein, M.D., Ph.D., FESC, Chief Scientific Officer of NewAmsterdam. “We are also pleased with the overall tolerability profile, including adverse events of special interest.”

Obicetrapib was observed to be well tolerated, with safety results comparable to placebo and no increase in blood pressure. The treatment discontinuation rate for the obicetrapib arm was 7.6% versus 14.4% for placebo. Adverse events of special interest are summarized in the table below.

Design of the Pivotal Phase 3 BROOKLYN Clinical Trial
The 52-week, global, pivotal, Phase 3, randomized, double-blind, placebo-controlled multicenter study evaluated the efficacy and safety of 10 mg obicetrapib compared to placebo as an adjunct to maximally tolerated lipid-lowering therapies in patients with HeFH whose LDL-C is not adequately controlled. The study was conducted at sites in North America, Europe and Africa. A total of 354 patients were randomized 2:1 to receive 10 mg obicetrapib or placebo dosed as a once-daily oral treatment, with or without food. The mean baseline LDL-C for enrolled patients in the obicetrapib arm was 123 mg/dL despite high intensity statin use reported by approximately 79% of patients during screening, with 54% on ezetimibe and 14% on PCSK9 inhibitors. Females comprised approximately 53% of the study population and the median age of participants at baseline was 57 years.

The primary endpoint was percent change from baseline in LDL-C of obicetrapib 10 mg compared to placebo after 84 days. Secondary endpoints also included percent changes from baseline of obicetrapib 10 mg compared to placebo after 84 days in HDL-C, non- HDL-C, ApoB, and Lp(a). 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 studies 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 from BROOKLYN in the third quarter of 2024.
• BROADWAY is evaluating obicetrapib in adult patients with established atherosclerotic cardiovascular disease (“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 expects to report topline data in the fourth quarter of 2024.
• TANDEM is evaluating obicetrapib as part of a FDC tablet with ezetimibe, a non-statin oral LDL-lowering therapy, in patients with established 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 completed enrollment of over 400 patients in July 2024 and expects to report 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 trial, 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 conducting an additional Phase 3 pivotal trial BROADWAY, 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 fixed-dose combination. The Company began enrolling patients in BROADWAY in January 2022 and in TANDEM in March 2024; completing enrollment of BROADWAY in July 2023, and TANDEM in July 2024. 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. 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.
