NAARDEN, the Netherlands and MIAMI, June 03, 2023 (GLOBE NEWSWIRE) -- NewAmsterdam Pharma Company N.V. (Nasdaq: NAMS or “NewAmsterdam” or the “Company”), a clinical-stage biopharmaceutical company developing oral, non-statin medicines for patients at high risk of cardiovascular disease (“CVD”) with residual elevation of low-density lipoprotein cholesterol (“LDL-C” or “LDL”), for whom existing therapies are not sufficiently effective or well-tolerated, today announced the full results of ROSE2, a Phase 2 clinical trial evaluating obicetrapib, the Company’s oral, low-dose and once-daily cholesteryl ester transfer protein (“CETP”) inhibitor, in combination with ezetimibe as an adjunct to high-intensity statin therapy. The data are being presented in an oral late-breaker presentation today at the National Lipid Association (“NLA”) Scientific Sessions 2023 and will be published concurrently in the Journal of Clinical Lipidology.
ROSE2 met its primary and secondary endpoints, with statistically significant and clinically meaningful reductions in LDL-C and apolipoprotein B (“ApoB”) observed. Statistically significant improvements in lipoprotein(a) (“Lp(a)”), non-HDL cholesterol (“non-HDL-C”) and total and small LDL particles were also observed. In addition, the combination of obicetrapib and ezetimibe was observed to be well-tolerated, with a safety profile observed to be comparable to placebo. With these data in hand, the Company has selected a formulation for a fixed-dose combination tablet and intends to advance the compound into a Phase 3 trial in the first quarter of 2024.
“The 2022 ACC Expert Consensus Decision Pathway has recommended that very high risk patients with LDL-C above 55mg/dl need additional therapy to maximize proven risk reduction. With these new recommendations, many more patients will fail to achieve guideline-mandated LDL-C goals, demonstrating the limitations of existing therapeutics and the critical need for new options,” said Christie M. Ballantyne, M.D., Chief of Cardiovascular Research and Professor at Baylor College of Medicine and principal investigator on the clinical trial. “The data presented today are highly encouraging, showing that the combination of obicetrapib and ezetimibe delivers robust impacts on multiple atherogenic lipid parameters. I believe the observed reductions in LDL-C, ApoB, Lp(a) and total and small LDL particles are potentially predictive of profound reductions in the risk of cardiovascular events and look forward to further characterizing the combination obicetrapib and ezetimibe regimen in a Phase 3 trial.”
“The ROSE2 data build on our prior clinical experience, supporting the potential for obicetrapib to become a new standard-of-care combined safely with existing options to deliver improved outcomes to the millions of very high-risk patients in need. We are particularly encouraged by the new goal attainment data announced today, through which we observed that 87 percent of patients treated with the combination regimen of obicetrapib and ezetimibe met the most aggressive guideline-mandated LDL-C target of <55 mg/dL,” said Michael Davidson, M.D., Chief Executive Officer of NewAmsterdam, “We have selected a fixed-dose combination tablet formula and look forward to advancing it into a Phase 3 trial, targeted to commence in the first quarter of 2024. In addition, we continue to progress our ongoing BROADWAY, BROOKLYN and PREVAIL trials according to plan. We believe that clinicians and patients are seeking oral options in addition to maximally tolerated statin therapy to reduce the risk of cardiovascular disease. Obicetrapib 10mg as monotherapy and in a fixed dose combination with ezetimibe, if successful in our Phase 3 trials, could well be the therapeutic solution that is so sorely needed.”
Full Data from the Phase 2 ROSE2 Clinical Trial of Obicetrapib and Ezetimibe
ROSE2 (NCT05266586) was designed as a placebo-controlled, double-blind, randomized Phase 2 clinical trial to evaluate the efficacy, safety and tolerability of obicetrapib 10 mg in combination with ezetimibe 10 mg as an adjunct to high-intensity statin therapy. Patients were randomized to receive combination therapy, obicetrapib 10 mg or placebo for a 12 week treatment period. A total of 119 patients enrolled in ROSE2, of which 97 were included in the on-treatment analysis. Patients presented at baseline with a fasting LDL-C greater than 70 mg/dL and triglycerides (“TG”) less than 400 mg/dL and all were receiving a stable dose of high-intensity statin therapy.
The primary endpoint was the percent change from baseline to week 12 in Friedewald-calculated LDL-C for the obicetrapib plus ezetimibe combination treatment group compared with placebo. Secondary efficacy endpoints included the percent changes from baseline to week 12 in LDL-C for obicetrapib monotherapy compared with placebo and in ApoB for the obicetrapib plus ezetimibe combination compared with placebo and the obicetrapib monotherapy compared with placebo. Exploratory endpoints included the percent changes from baseline to week 12 in Lp(a), non-HDL-C, HDL-C, total and small LDL particles assessed by NMR, and the proportion of patients at the end of treatment who achieved LDL-C levels below 100 mg/dL, 70 mg/dL and 55 mg/dL for the obicetrapib plus ezetimibe combination and obicetrapib monotherapy groups compared with placebo.
The p-value for the LS mean for each endpoint compared to placebo was <0.0001. The table below shows the median percent change from baseline in patients receiving the combination of obicetrapib and ezetimibe, obicetrapib monotherapy and placebo.
|Median percent change from baseline
mg + Ezetimibe 10
|Total LDL particles
|Small LDL particles
|LDL particle size
The combination of obicetrapib plus ezetimibe resulted in significantly more patients achieving LDL-C levels of less than 100, less than 70 and less than 55 mg/dL than the placebo group (100%, 93.5% and 87.1% vs. 66.7%, 16.7% and 0.0%, respectively) (p<0.05 vs. placebo for all). In addition, we observed a median reduction in Lp(a) of 47.2% and 40.2% in the monotherapy and combination arms, respectively.
Treatment with the combination of obicetrapib and ezetimibe was observed to be generally well-tolerated, with a safety profile comparable to placebo. Adverse events were generally mild to moderate, with the most prevalent adverse events being nausea, urinary tract infection and headache, and no drug-related, treatment-emergent serious adverse events were observed.
“We are particularly encouraged by the new lipid particle analysis, in which we observed reductions in Lp(a) and both total and small LDL particles in patients who received the combination of obicetrapib and ezetimibe,” said John Kastelein, M.D., Ph.D., FESC, Chief Scientific Officer of NewAmsterdam. “An observed reduction of almost 50% in Lp(a) levels and associated reduction of 95% in the highly atherogenic small LDL particles are potentially clinically relevant, as LDL particles are believed to be one of the most robust predictors of cardiovascular disease risk. Together, these data further reinforce the potential for obicetrapib to transform the treatment landscape.”
Under the terms of NewAmsterdam’s licensing agreement with the Menarini Group, data from the ROSE2 trial triggered a clinical success milestone payment to NewAmsterdam, which was received in April 2023.

Obicetrapib is a next-generation, oral, low-dose CETP inhibitor that NewAmsterdam is developing to potentially 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 all three of the Company’s Phase 2 trials, TULIP, ROSE and OCEAN, evaluating obicetrapib as a monotherapy or a combination therapy, the Company observed statistically significant LDL-lowering activity combined with generally moderate side effects and no drug-related, treatment-emergent serious adverse events. Obicetrapib has demonstrated strong tolerability in more than 600 patients with low or 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 potentially enhance LDL-lowering for high-risk CVD patients. The Company began enrolling patients in BROADWAY in January 2022 and in BROOKLYN in July 2022 and completed enrollment of BROOKLYN ahead of schedule in April 2023. The Company also commenced the Phase 3 PREVAIL CVOT in March 2022, which is designed to assess the potential of obicetrapib to reduce occurrences of MACE, including cardiovascular death, non-fatal myocardial infarction, non-fatal stroke and non-elective coronary revascularization.
NewAmsterdam (Nasdaq: NAMS) is a clinical-stage biopharmaceutical company whose mission is to improve patient care in populations with metabolic diseases where currently approved therapies have not been sufficiently successful or well tolerated. NewAmsterdam is investigating obicetrapib, an oral, low-dose and once-daily CETP inhibitor, as the preferred LDL-C lowering therapy to be used as an adjunct to maximally tolerated statin therapy for high-risk cardiovascular disease (“CVD”) patients. Results from NewAmsterdam’s ROSE Phase 2b trial (presented at AHA Scientific Sessions in 2021) included observations that patients receiving obicetrapib 10 mg experienced a median reduction in LDL-C of 51% versus baseline in patients on high-intensity statin therapy (vs. a 7% reduction in the placebo arm). In addition, results from NewAmsterdam’s ROSE2 trial evaluating the combination of 10 mg obicetrapib and 10 mg ezetimibe demonstrated a median reduction in LDL-C levels of 63% versus baseline in patients on high-intensity statin therapy (vs. a 6% reduction in the placebo arm). Based in the Netherlands, NewAmsterdam recently completed a business combination with Frazier Lifesciences Acquisition Corporation (“FLAC”), a special purpose acquisition company sponsored by an affiliate of Frazier Healthcare Partners. Proceeds from this transaction were approximately $328 million, prior to deducting transaction expenses. In June 2022, NewAmsterdam entered into an exclusive licensing agreement with the Menarini Group for the commercialization of obicetrapib in Europe, while retaining all rights to commercialize obicetrapib, if approved, in the rest of the world, as well as rights to develop certain forms of obicetrapib for other diseases such as Alzheimer’s disease.
