Portfolio by Design

Genetic medicines designed to be safe and specific forcardiometabolic disease (CMD)

We’re building a portfolio of genetic medicines for cardiometabolic disease (CMD) using our gene editing and epigenetic silencing platforms. We prioritize genetic targets with clinically-validated biology and demonstrated patient benefit from on-target modification, starting with targeting PCSK9 to address cardiovascular disease associated with LDL-C.

Programs listed include STX1100/1150 for elevated LDL-C targeting PCSK9, STX1400 for SHTG & FCS targeting APOC3, and several undisclosed cardiometabolic targets. Blue bars indicate current progress through development stages.

Why treat cardiometabolic disease (CMD)?

Despite availability of existing medications, CVD remains the leading cause of death globally.

It doesn’t have to be this way. For common conditions like CMD, genetic medicines have the potential to be once-in-a-lifetime therapies that fundamentally lower people’s major risks.

We’re addressing the greatest unmet need in healthcare by deliberately engineering therapeutics to become the standard of care for CMD.

Why target LDL-C?

Low-density lipoprotein cholesterol (LDL-C) is a key driver of dyslipidemia and cardiovascular risk. Elevated LDL-C levels in the bloodstream can promote the formation of plaques in arterial walls, restricting blood flow and increasing the risk of heart attacks and strokes. Lowering LDL-C effectively reduces the risk of major cardiovascular events.

Cardiovascular risk is cumulative, thus the unmet need for effective LDL-C-lowering treatments that start earlier in disease progression is even greater. Today’s standard of care is insufficient - the chronic care model is plagued with high treatment burden, safety concerns, and lack of early intervention, leading to suboptimal outcomes.

Our LDL-C lowering programs are starting with targeting PCSK9 to address cardiovascular disease associated with LDL-C. Our candidates are designed to be used earlier, with persistent durability, replicating the low lifetime risk profile of individuals with favorable PCSK9 genetics.

Today

Typical patient journey over time

A timeline visualization showing the traditional progression of heart disease treatment, displayed as mirrored red and blue bars. The progression moves from initial symptoms and statin prescription through increasingly intensive interventions including additional medications (ezetimibe, bempedoic acid, PCSK9), stents, and bypass surgery. Key events are marked including first heart attack, medication cessation, second heart attack, and ultimately fatal heart attack. Treatment interventions are shown in blue on the left while disease progression is shown in red on the right.

Tomorrow

With genetic medicine over time

A simplified treatment timeline visualization illustrating the potential future of genetic medicine, with three key concepts labeled in black boxes: 'PREVENTATIVE', 'UNIVERSAL', and 'LIBERATING'. The diagram includes explanatory text boxes highlighting early screening and prevention, CRISPR's universal applicability, and the benefit of one-time treatments replacing lifetime medication. The visualization uses minimal blue and red bars to contrast with the more complex traditional treatment timeline.

Partnerships

Our CRISPR-based platforms have the potential to create life-changing genetic medicines across a broad spectrum of disease. We’re leveraging collaborations with world-leading pharmaceutical companies to expand our patient impact.

In preclinical studies, we’ve observed gene editing at or near saturating levels across several major organ systems and tissue types, including the central nervous system, muscle, liver, and eye. We’ve similarly demonstrated high levels of editing in ex vivo applications.

Given these promising results, we are committed to broadening and accelerating the potential impact of our platforms into other therapeutic areas via strategic collaborations with leading partners.
