– Study Met the Primary Endpoint Demonstrating Clinically Significant Systolic Blood Pressure Reductions at Month 3 When Zilebesiran Was Added to a Diuretic, Calcium-Channel Blocker or Angiotensin Receptor Blocker –
– Zilebesiran Demonstrated an Encouraging Safety and Tolerability Profile When Added to Standard of Care Antihypertensives –
– Study Results Support Potential for Biannual Dosing of Zilebesiran –
– Full Study Results to Be Presented as a Late-Breaking Clinical Trial at the 2024

“We are thrilled that a single dose of zilebesiran achieved clinically significant, additional reductions in systolic blood pressure when administered to patients
The KARDIA-2 Phase 2 study is a randomized, double-blind (DB), placebo-controlled study designed to evaluate the efficacy and safety of zilebesiran, when added to standard of care antihypertensive medications, in adults with mild-to-moderate hypertension. This global, multicenter study enrolled 672 adults with hypertension. Patients
The primary endpoint is the change from baseline in mean SBP at Month 3, assessed by 24-hour ABPM. Additional endpoints include the change in 24-hour mean SBP after six months of treatment assessed by ABPM, change in office SBP at Month 3 and Month 6, and change in diastolic blood pressure (DBP) measured by ABPM and office blood pressure at Month 3 and Month 6. Safety will be assessed throughout the study.
The primary endpoint is the change from baseline at Month 3 in mean seated office SBP. Additional endpoints include change from baseline at Month 3 in 24-hour mean SBP assessed by ABPM, change from baseline at Month 6 in mean seated office SBP and in 24-hour mean SBP assessed by ABPM. Safety will be assessed throughout the study.
About Zilebesiran
Zilebesiran is an investigational, subcutaneously administered RNAi therapeutic targeting angiotensinogen (AGT) in development for the treatment of hypertension in high unmet need populations. AGT is the most upstream precursor in the Renin-Angiotensin-Aldosterone System (RAAS), a cascade which has a demonstrated role in blood pressure (BP) regulation and its inhibition has well-established anti-hypertensive effects. Zilebesiran inhibits the synthesis of AGT in the liver, potentially leading to durable reductions in AGT protein and ultimately, in the vasoconstrictor angiotensin (Ang) II. Zilebesiran utilizes Alnylam’s Enhanced Stabilization Chemistry Plus (ESC+) GalNAc-conjugate technology, which enables infrequent subcutaneous dosing with increased selectivity and the potential to achieve tonic blood pressure control demonstrating consistent and durable blood pressure reduction throughout a 24-hour period, sustained up to six months after a single dose of zilebesiran. The safety and efficacy of zilebesiran have not been established or evaluated by the FDA, EMA or any other health authority. Zilebesiran is being co-developed and co-commercialized by
About Hypertension
Uncontrolled hypertension is the chronic elevation of blood pressure (BP), defined by the 2017 ACC/AHA guidelines as ≥130 mmHg systolic blood pressure (SBP) and ≥80 mmHg diastolic blood pressure (DBP). More than one billion people worldwide live with hypertension.i Approximately one in three adults are living with hypertension worldwide, with up to 80% of individuals remaining uncontrolled despite the availability of several classes of oral anti-hypertensive treatments. Despite the availability of anti-hypertensive medications, there remains a significant unmet medical need, especially given the poor rates of adherence to existing daily oral medications, resulting in inconsistent BP control and an increased risk for stroke, heart attack and premature death.ii In particular, there are a number of high unmet need settings where novel approaches to hypertension warrant additional development focus, including patients with poor medication adherence and in patients with high cardiovascular risk.
About RNAi
RNAi (RNA interference) is a natural cellular process of gene silencing that represents one of the most promising and rapidly advancing frontiers in biology and drug development today. Its discovery has been heralded as “a major scientific breakthrough that happens once every decade or so,” and was recognized with the award of the 2006 Nobel Prize for Physiology or Medicine. By harnessing the natural biological process of RNAi occurring in our cells, a new class of medicines known as RNAi therapeutics is now a reality. Small interfering RNA (siRNA), the molecules that mediate RNAi and comprise
