Verve Therapeutics Reports New Preclinical Data Demonstrating Potent and Durable Editing of ANGPTL3 Gene with VERVE-201 in Wild-type and LDLR-deficient Non-Human Primates

Mar 3, 2023

VERVE-201 Preclinical Data Supports Advancement of Drug Candidate Toward Clinical Development for Homozygous Familial Hypercholesterolemia, with Initiation of Clinical Trial Anticipated in 2024

Data to be Presented During an Oral Presentation at the 2023 American College of Cardiology’s Annual Scientific Sessions Meeting

BOSTON, March 03, 2023 (GLOBE NEWSWIRE) -- Verve Therapeutics, Inc., a clinical-stage biotechnology company pioneering a new approach to the care of cardiovascular disease with single-course gene editing medicines, today reported new preclinical data in non-human primates (NHPs) demonstrating potent, durable and well-tolerated editing of the ANGPTL3 gene following administration of VERVE-201.

The VERVE-201 development candidate is composed of messenger RNA for an adenine base editor and a guide RNA designed to target the ANGPTL3 gene packaged in Verve’s proprietary lipid nanoparticle (LNP) technology, GalNAc-LNP. Delivered via a one-time intravenous infusion, VERVE-201 is designed to permanently inactivate the ANGPTL3 gene in liver cells, turn off liver production of blood ANGPTL3, and thereby durably reduce blood levels of disease-driving low-density lipoprotein cholesterol (LDL-C) and triglyceride-rich lipoproteins (TRLs). VERVE-201 is initially being developed for the treatment of homozygous familial hypercholesterolemia (HoFH), a rare and often fatal genetic subtype of premature atherosclerotic cardiovascular disease (ASCVD) characterized by extremely high blood LDL-C. VERVE-201 aims to reduce the heavy treatment burden associated with available therapies for HoFH including the requirement for multiple oral, injectable, and intravenous infusions in each patient, often administered over decades. Ultimately, beyond HoFH, Verve may develop VERVE-201 for a broader population of patients with refractory hypercholesterolemia, defined as ASCVD patients with LDL-C that is refractory to treatment with available oral and injectable options for LDL-C lowering, such as PCSK9 inhibitors.

“We are highly encouraged by the data that continue to emerge for our second program, VERVE-201, which aims to address multiple ASCVD indications through inactivation of the ANGPTL3 gene,” said Andrew Bellinger, M.D., Ph.D., chief medical and scientific officer of Verve. “ASCVD is not only a devastating but also a challenging group of indications to treat, requiring multiple treatment options for patients. Targeting the ANGPTL3 gene is a key component of our strategy to address ASCVD broadly by designing medicines to reduce each of the three known causal drivers of ASCVD – LDL-C, TRLs and lipoprotein(a). With VERVE-201, further supported by today’s data, we believe we may be able to impact two of these pathways—LDL-C and TRLs—by creating a precise edit in the ANGPTL3 gene without making a double-stranded DNA break. With these findings, we continue to progress VERVE-201 toward clinical development, with plans to initiate a first-in-human clinical trial in 2024 in people with HoFH, so that we may ultimately offer these patients a potential safe and effective, once-and-done treatment option for their disease.”

To support advancement of VERVE-201 toward clinical development, Verve is evaluating the candidate in numerous preclinical studies and today, reported preclinical data in NHPs. VERVE-201cyn, the NHP surrogate of VERVE-201, was studied in 34 wild-type NHPs, across three groups: control (n=12), 1.5 mg/kg dose (n=6) and 3.0 mg/kg dose (n=16). Key results showed:

  • Mean whole liver DNA editing at the ANGPTL3 gene of 55% and 63% and mean blood ANGPTL3 protein reduction from baseline of 89% and 96%, at 1.5mg/kg (n=6) and 3.0mg/kg doses (n=16), respectively, with durable effects observed out to six months following treatment
  • Decreased liver triglyceride mass, a nonclinical surrogate for hepatic fat accumulation, in NHPs treated with either 1.5 mg/kg or 3.0 mg/kg of VERVE-201cyn as compared to vehicle control, when assessed six months following treatment
  • VERVE-201cyn was well-tolerated with only transient impacts on alanine aminotransferase (ALT) and aspartate aminotransferase (AST) that resolved by day 14 and there was no observed impact on total bilirubin levels
  • On-target ANGPTL3 editing was detected primarily in the liver, with a lower degree of ANGPTL3 editing in adrenal and spleen tissues and minimal ANGPTL3 editing elsewhere, consistent with the biodistribution of LNPs

In an additional study, Verve evaluated VERVE-201’s potential in an LDL receptor (LDLR)-deficient NHP model designed to mimic the physiology of patients with HoFH. Patients with HoFH have severe or complete LDLR deficiency, which limits the ability of traditional LNPs to deliver base editing medicines to the liver. Verve has developed its proprietary GalNAc-LNP to allow for uptake via an additional receptor, the asialoglycoprotein receptor (ASGPR), which is expected to enable delivery independent of LDLR. Verve first developed LDLR-deficient NHPs (n=4), resulting in an increase in mean LDL-C from 55 to 458 mg/dL. Subsequent treatment in these NHPs with VERVE-201cyn at a dose of 3.0 mg/kg led to:

  • Mean whole liver DNA editing at the ANGPTL3 gene of 60% and a mean 84% reduction in blood ANGPTL3 protein
  • Mean 46% decrease in LDL-C (from 458 to 247 mg/dL) and a mean 54% decrease in circulating triglycerides

Verve also reported preclinical findings in Ldlr-knockout mice fed a high-fat Western diet, in which administration of VERVE-201mu, as compared to control, led to a 97% reduction in blood ANGPTL3 protein, a 47% reduction in LDL-C and a 72% reduction in triglycerides.

About Verve Therapeutics
Verve Therapeutics, Inc. (Nasdaq: VERV) is a clinical-stage genetic medicines company pioneering a new approach to the care of cardiovascular disease, potentially transforming treatment from chronic management to single-course gene editing medicines. The company’s initial two programs – VERVE-101 and VERVE-201 – target genes that have been extensively validated as targets for lowering low-density lipoprotein cholesterol (LDL-C), a root cause of cardiovascular disease, in order to durably reduce blood LDL-C levels. VERVE-101 is designed to permanently turn off the PCSK9 gene in the liver and is being developed initially for heterozygous familial hypercholesterolemia (HeFH) and ultimately to treat atherosclerotic cardiovascular disease (ASCVD) patients not at goal on oral therapy. VERVE-201 is designed to permanently turn off the ANGPTL3 gene in the liver and is initially being developed in homozygous familial hypercholesterolemia (HoFH) and ultimately to treat patients with refractory hypercholesterolemia.
