NewAmsterdam Pharma Company N.V. (NASDAQ: NAMS) has released positive topline data from its pivotal phase 3 Brooklyn clinical trial evaluating obicetrapib in patients with heterozygous familial hypercholesterolemia (HeFH). The trial achieved its primary endpoint of LS mean reduction in low-density lipoprotein cholesterol (LDL-C) on top of maximally tolerated lipid-modifying therapies at day 84 with a statistically significant reduction (p<0.0001), which was sustained at day 365 (p<0.0001). Obicetrapib lowered LDL-C by 36.3% at day 84 and 41.5% at day 365, compared to placebo.
The trial demonstrated that obicetrapib was generally 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.
In terms of adverse events, the incidence of treatment-emergent adverse events, study-drug related adverse events, and treatment-emergent serious adverse events were all lower in the obicetrapib arm compared to placebo. Additionally, the observed reductions in other biomarkers, including high-density lipoprotein cholesterol, non-HDL-C, lipoprotein(a), and apolipoprotein B, met statistical significance and were consistent with data reported from the company’s prior clinical trials.
The pivotal phase 3 Brooklyn clinical trial was a 52-week, global, randomized, double-blind, placebo-controlled multicenter study that 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.
NewAmsterdam's CEO, Michael Davidson, expressed excitement about the results from the Brooklyn trial and emphasized the potential of obicetrapib to significantly reduce LDL-C in a challenging patient population over a duration of one year. He also highlighted that adverse events and discontinuations due to side effects were similar to placebo, consistent with observations from phase 2 studies.
The company plans to present full results from the Brooklyn trial at an upcoming medical conference and to publish the data in a major medical journal.
Obicetrapib is part of NewAmsterdam’s global pivotal phase 3 program, which consists of four studies in over 12,250 patients, including the Brooklyn trial, and upcoming trials such as Broadway and Tandem.
