Imagine if… there was a …safely and permanently Such a medicine has “once-and-done” lowered blood LDL cholesterol potential to treat and treatment that… and/or triglycerides. ultimately eradicate coronary heart disease. 2
Pioneering a pipeline of “once-and-done” gene editing medicines to treat coronary heart disease DEVELOPMENT STATUS PROGRAM INDICATION Research Lead optimization IND-Enabling Phase 1 Phase 2/3 Low-density lipoprotein (LDL) VERVE-101 Heterozygous familial ABE-PCSK9 hypercholesterolemia Triglyceride-rich lipoprotein (TRL) ANGPTL3 Undisclosed Lipoprotein(a) Lp(a) LPA Undisclosed 3
Coronary heart disease (CHD) is a leading health problem worldwide, with blood LDL cholesterol (LDL-C) clogging heart arteries Atherosclerotic Plaque Caused by LDL-C #1 cause of death globally 24 million with CHD in US/Europe 1.6 million with monogenic subtype: familial hypercholesterolemia Site of Blockage 5
Familial hypercholesterolemia is a life-threatening genetic disease with high cumulative exposure to LDL-C causing early CHD and stroke High genetic risk: • Familial hypercholesterolemia (FH) • Genetic disease, high blood LDL-C • Early coronary disease, stroke, death • 1.6 million people in U.S & Europe 6
Targets to treat FH and CHD: genes that harbor resistance mutations which lower LDL-C lifelong Low genetic risk: • Resistance mutation lowers LDL-C • Turns off any of 8 genes • All expressed in liver • Include ANGPTL3 and PCSK9 7
Individuals who naturally lack ANGPTL3 gene have lifelong low blood lipids, are healthy and resistant to heart attack Target gene de-risked by human genetics Human knockout: Extremely low blood lipids, healthy mg/dl Triglycerides: 19 LDL-C: 37 mg/dl By Gina Kolata May 24, 2017 Anna Feurer learned she had unusually low triglyceride levels after having bloodwork at a Heterozygous deficiency: corporate health fair. The discovery prompted researchers to recruit Low lipids her and her family for a research study of their Resistant to heart attack genetic makeup. Credit. Jess T. Dugan for The New York Times Musunuru et al., N Engl J Med 2010 8
Individuals who naturally lack PCSK9 gene have lifelong low blood LDL-C, are healthy and resistant to heart attack Low genetic Target gene de-risked Human knockout: risk population by human genetics Extremely low LDL-C, healthy 14 mg/dl By Gina Kolata July 9, 2013 Heterozygous deficiency: Low LDL-C Her cholesterol was Resistant to heart attack astoundingly low. Her low-density lipoprotein, or LDL, the form that promotes heart disease, was 14, a level unheard- of in healthy adults, whose normal level is over 100. The reason was a rare gene mutation she had inherited from both her mother and her father. Cohen et al., N Engl J Med 2006; 354:1264-1272 9
Can we transform care of coronary heart disease from daily pills/intermittent injections to “once-and-done?”
Gene editing technologies to permanently turn off either PCSK9 or ANGPTL3 in the liver: Cas9 vs base editing editing domain A DNA PAM DNA PAM ≈20 nucleotides ≈20 nucleotides guide RNA guide RNA Cas protein catalytically impaired Cas9 Cas protein Cpf1/Cas12a base editors C2c1/Cas12b double-strand break (modified from gene deamination of CRISPR systems) cytidine to uridine or adenosine to inosine non-homologous end-joining repair process (error-prone) G disruption of gene introduction of CàT or AàG change 11
Prioritized DNA adenine base editing (ABE) technology to precisely & permanently turn off PCSK9 or ANGPTL3 in liver More potent Better safety profile due to absence of double-strand breaks Base editing of liver cells Exclusive IP access from Beam turns off a gene and lowers LDL-C in the blood 12
VERVE-101 is a lipid nanoparticle (LNP) containing mRNA for ABE & a guide RNA targeting PCSK9 1. mRNA for ABE 2. guide RNA targeting PCSK9 Electron 3. Amino lipid micrograph of 4. Cholesterol Lipid VERVE-101 5. DSPC components 6. PEG-lipid 60 nm • Single course treatment • Intravenous infusion over ~60 min 13

Why a “once-and-done” medicine when there is a standard of care for cholesterol lowering?
FH: high cumulative exposure to blood LDL-C is the problem 200 Patient with 150 heterozygous FH: LDL-C LDL-C in 200s mg/dl starting at birth 100 50 40 45 50 55 60 65 70 Age 28
Current care model: cumulative LDL-C exposure remains high over life-course Stent Fatal heart attack 200 Standard of care: lifestyle + statin Patient with heterozygous FH & 150 first heart attack at age 44: LDL-C standard of care mg/dl 100 in the real world Add PCSK9i mAb or siRNA Lost job, lost health insurance 50 ”Feeling well”: self-stopped all medicines Missed MD appointment, failed to re-fill prescription for 1y 40 45 50 55 60 65 70 Age 29
