Verve Therapeutics Announces 2022 Anticipated Milestones and Preclinical Data on Potential Additional Dosing Regimens for its Novel Base Editing Programs
01/10/2022 - 06:30 AM
VERVE-101 Regulatory Submissions and First Patient Treated On-track for Second Half of 2022
ANGPTL3 Program Initiation of IND-Enabling Studies Expected in the Second Half of 2022
Preclinical Data in Non-Human Primates Demonstrate Potential to Re-Dose or Sequentially Dose Base Editing Programs
CAMBRIDGE, Mass., Jan. 10, 2022 (GLOBE NEWSWIRE) -- Verve Therapeutics , Inc., (Nasdaq: VERV), a biotechnology company pioneering a new approach to the care of cardiovascular disease with single-course gene editing medicines, today highlighted key milestones anticipated in 2022 and announced new preclinical data in non-human primates (NHPs) on additional potential dosing regimens for its base editing programs for the treatment of atherosclerotic cardiovascular disease (ASCVD) indications.
“2021 was a year of remarkable progress across all aspects of our company, with data demonstrating robust and durable gene editing and well-tolerated safety profiles with both VERVE-101 and our ANGPTL3 base editor in NHP studies. We successfully executed our IPO and further strengthened our team with several highly talented individuals,” said Sekar Kathiresan, M.D., co-founder and chief executive officer of Verve. “As we look ahead, we expect 2022 will be a transformative year, with additional data expected at scientific and medical meetings throughout the year, leading to our planned transition to a clinical-stage organization in the second half of 2022. As pioneers in the industry for the treatment of cardiovascular disease, we have the opportunity to fundamentally shift how patients with ASCVD are treated and look forward to reporting more progress in the coming months.”
2022 Anticipated Milestones Previously reported data in NHPs demonstrated that a single administration of VERVE-101 led to robust, durable editing of the PCSK9 gene. Key program milestones anticipated in 2022 include:
Clinical trial application (CTA) and investigational new drug (IND) submissions in the second half of 2022, and First HeFH patient treated in a Phase 1 clinical trial in the second half of 2022. Verve’s second program is designed to permanently turn off the ANGPTL3 gene, a key regulator of cholesterol and triglyceride metabolism. Verve plans to develop this program initially for the treatment of both homozygous familial hypercholesterolemia (HoFH) and HeFH. Previously reported data have demonstrated that a single administration of Verve’s ANGPTL3-targeting base editor led to potent reductions in blood ANGPTL3 protein levels and LDL-C in a novel NHP model of HoFH. Key program milestones anticipated in 2022 include:
Development candidate selection in the second half of 2022, and IND-enabling studies to begin in the second half of 2022. Preclinical Re-Dosing and Sequential Dosing Data
“The best way to treat ASCVD in a patient is to lower circulating LDL-C as much as possible and for as long as possible,” said Andrew Bellinger, M.D., Ph.D., chief scientific officer and chief medical officer of Verve. “We’ve generated preclinical data in NHPs that support our ability to potentially re-dose our PCSK9 base editor. We have also generated data in NHPs that supports our ability to potentially sequentially dose our PCSK9 base editor followed by our ANGPTL3 base editor, which may expand the number of patients who are able to benefit from our therapies. We believe these data are among the first demonstration in NHPs of re-dosing as well as in vivo sequential editing of multiple targets and highlight one of the potential key advantages of lipid nanoparticles (LNPs) as a delivery approach for gene editing medicines.”
To assess the potential for repeat dosing, Verve conducted a study in NHPs (n=4), in which 0.5 mg/kg of a VERVE-101 precursor was dosed on days 1, 30 and 60 in a 90-day study. Editing of PCSK9 was measured in liver biopsy after each dose on days 14, 46 and 75, and in liver necropsy on day 90. Verve observed an increase in PCSK9 editing over the course of the study, with an average of 29% at day 14, 36% at day 46, 53% at day 75 and 59% at day 90. These data suggest that repeat low doses of a PCSK9 base editor could achieve a high level of liver editing. Importantly, no evidence of liver injury was observed following any of the doses, which provides evidence of the low immunogenicity of LNPs in NHPs.
Patients with very high LDL-C or those with combined hyperlipidemia with high LDL-C and high triglycerides may benefit from gene editing medicines that target two lipid pathways, such as PCSK9 and ANGPTL3. To assess the potential for sequential dosing, Verve conducted a 90-day study in NHPs (n=4), in which 1.0 mg/kg of a VERVE-101 precursor was administered on day 1, followed by administration of 1.0 mg/kg of an ANGPTL3 base editor on day 30. PCSK9 editing was measured by liver biopsy on day 15, showing an average of 71% editing, and ANGPTL3 editing was measured in a second liver biopsy on day 45, showing an average of 52% editing. In liver necropsy on day 90, an average of 69% PCSK9 editing and 63% ANGPTL3 editing was observed. Verve monitored plasma PCSK9 and ANGPTL3 protein levels during the study and observed a greater than 90% reduction of plasma PCSK9 protein after the first dose and a greater than 90% reduction of plasma ANGPTL3 protein after the second dose, with both reductions remaining durable to the conclusion of the study. These data suggest that sequential dosing of a PCSK9 base editor followed by an ANGPTL3 base editor may be administered to efficiently edit two genes that control key lipid pathways.
