NewAmsterdam Pharma Announces Publication in Nature Medicine Discussing Clinical Potential of Obicetrapib

— Full data support the potential of obicetrapib to address unmet medical need for millions of patients who cannot achieve their LDL-C targets with high-intensity statin therapy (HIS) alone —

— Treatment with obicetrapib in patients on high-intensity statin therapy was observed to have statistically significant impact on LDL-C, as well as significant impacts on ApoB, non-HDL-C, HDL-C and Lp(a), additional key measures of cardiovascular disease risk —

— Publication also details obicetrapib’s unique physiochemical properties, which enable the potential for improved potency over first-generation CETP inhibitors —

Naarden, the Netherlands and Miami, USA; August 11, 2022 – NewAmsterdam Pharma (NewAmsterdam), a clinical-stage company focused on the research and development of transformative oral therapies for metabolic diseases, today announced the publication of full results from the Phase 2b Randomized Study of Obicetrapib as an Adjunct to Statin Therapy (ROSE) clinical trial in the peer-reviewed journal, Nature Medicine. The article, titled “Lipid lowering effects of the CETP inhibitor obicetrapib in combination with high-intensity statins: a randomized phase 2 trial,” is available online at: https://www.nature.com/articles/s41591-022-01936-7. Obicetrapib is NewAmsterdam’s next-generation oral, low-dose and once-daily cholesteryl ester transfer protein (CETP) inhibitor, initially in development for patients at high risk for cardiovascular disease as an adjunct to maximally tolerated statin therapy, both as a monotherapy and in a fixed-dose combination with ezetimibe.

In addition to the previously announced data, in which it was observed that obicetrapib significantly lowered low density lipoprotein cholesterol (LDL-C) in patients on high-intensity statins (HIS), data published in the Nature Medicine manuscript included significant observations for other lipid changes in the treatment arm, which are believed to be clinically meaningful. As compared to placebo, treatment with obicetrapib led to statistically significant changes from baseline in apolipoprotein B (ApoB), non-high density lipoprotein cholesterol (non-HDL-C) concentration, HDL-C concentration and lipoprotein(a) (Lp(a)), with all effects observed in a dose-dependent manner. The data below illustrates the median percent change in lipid levels against baseline as follows:

Obicetrapib was well tolerated in the trial, with adverse event rates similar across placebo and obicetrapib arms. Treatment emergent adverse events (TEAEs) were reported by 15 subjects in the 5 mg group and eight subjects in the 10 mg group, compared with 19 subjects in the placebo group. TEAEs that were considered by the investigator to be related to study treatment were reported by two subjects (one subject in the 5 mg and 10 mg groups, respectively), compared with four subjects in the placebo group. The majority of TEAEs were mild and moderate in severity; one subject in the placebo group had a severe TEAE. The publication also highlights obicetrapib’s unique structural scaffold and physiochemical properties that enables the potential for it to be a significantly more potent CETP inhibitor than prior investigational compounds in the

class. A previously completed multiple ascending dose Phase 1 study of obicetrapib showed that CETP activity was inhibited by 90.9% and 97.6%, respectively, for the 5 and 10 mg doses. Although head-to-head clinical trials have not been conducted to date, these results are markedly greater than the CETP inhibition observed with anacetrapib and evacetrapib. A potential and partial explanation for this improved potency is the unique hydrophilic structure of obicetrapib, which is the most polar of all CETP inhibitors that have been in the clinic. It also has been observed to have better bioavailability and greater LDL-C lowering activity at lower doses.

Finally, the publication discusses evidence that the ApoB and LDL-C lowering effect of CETP inhibitors functions through increased clearance of ApoB-containing lipoproteins through the liver, the same mechanism of action as most other lipid lowering therapies. This further supports the belief that LDL-C lowering via obicetrapib will translate into improved cardiovascular outcomes for patients.

“The data published in Nature Medicine provide additional evidence that obicetrapib is a next-generation molecule that is clearly differentiated from prior CETP inhibitors, with the potential to overcome the safety and efficacy challenges that have historically limited the potential of the drug class,” said John Kastelein, M.D., Ph.D., FESC, chief scientific officer of NewAmsterdam Pharma and author on the Nature Medicine manuscript. “Together, the full results of ROSE demonstrate that obicetrapib has the potential to provide significant reductions in LDL-C as an adjunct to high intensity statins, while also improving other lipid biomarkers, like ApoB and Lp(a), which are increasingly recognized as important targets in cardiovascular disease. These data reinforce our confidence that we are advancing a potentially transformative cardiometabolic therapy, which if approved, could change the treatment paradigm for millions of patients who are inadequately managed on HIS therapy alone.”

“There is an urgent need to deliver a new convenient and cost-effective oral medicine for dyslipidemia, which delivers strong efficacy with a favorable safety profile,” said Michael Davidson, M.D., Chief Executive Officer at NewAmsterdam Pharma. “The new data published in Nature Medicine represent a growing consensus among the medical and research community that obicetrapib may fulfill this unmet need. We continue to enroll our ongoing Phase 3 studies and look forward to sharing additional data with the clinical community as we complete our BROADWAY and BROOKLYN trials, which is expected in 2024.”

NewAmsterdam Pharma is currently evaluating obicetrapib in three Phase 3 clinical trials, BROADWAY (LDL-lowering capability in patients on maximum tolerated lipid-modifying therapies with established atherosclerotic cardiovascular disease or heterozygous familial hypercholesterolemia (HeFH) with LDL-C ≥ 70 mg/dL), BROOKLYN (LDL-lowering capability in HeFH patients on maximum tolerated lipid-modifying therapies with LDL-C ≥ 70 mg/dL), and PREVAIL (CVOT in patients on maximum tolerated lipid-modifying with atherosclerotic cardiovascular disease with LDL-C ≥ 70 mg/dL), and a Phase 2b trial, ROSE2, which is examining obicetrapib as a fixed-dose combination therapy with obicetrapib 10 mg and ezetimibe 10 mg in patients on high-intensity statin therapy with LDL-C ≥ 70 mg/dL.

About NewAmsterdam Pharma

NewAmsterdam Pharma is a private clinical-stage biopharmaceutical company whose mission is to improve patient care in populations with metabolic diseases where traditional therapies have not been sufficiently successful or well-tolerated. NewAmsterdam Pharma is investigating obicetrapib, a next-generation oral, low-dose and once-daily CETP inhibitor, as the preferred LDL-C-lowering therapy for high-risk cardiovascular disease (“CVD”) patients. Results from NewAmsterdam Pharma’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 by 51% versus baseline in patients on statin therapy (vs. a 7% reduction in the placebo arm). Based in the Netherlands, NewAmsterdam Pharma was founded in 2019 by the venture capital firm Forbion and John Kastelein, Chief Scientific Officer of the NewAmsterdam Pharma, and closed a $196 million (€160 million) Series A financing in January 2021 led by Forbion, Morningside Ventures and Ascendant BioCapital. In June 2022, NewAmsterdam Pharma 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.
