PCSK9 Inhibitors Market Size, Target Population, Competitive Landscape & Market Forecast - 2034

Key Highlights:

• PCSK9-targeted therapies block the PCSK9 protein in the liver, preventing the breakdown of LDL receptors on hepatocytes. This increases receptor availability to clear LDL (bad) cholesterol from the blood, lowering LDL-C levels by ~50-60%.
• Currently marketed PCSK9-targeted therapies are approved for treating hypercholesterolemia, mixed dyslipidemia, primary hyperlipidemia, Heterozygous and Homozygous Familial Hypercholesterolemia (HeFH, HoFH), Atherosclerotic Cardiovascular Disease (ASCVD), and for preventing myocardial infarction, stroke, unstable angina requiring hospitalization, and coronary revascularization.
• PCSK9-targeted therapies not only lower LDL-C but also reduce the risk of cardiovascular events in patients with prior heart attack, stroke, or peripheral artery disease. They are indicated for both primary prevention and secondary prevention. In practice, they are prescribed alongside statins to maximize cholesterol reduction, or as alternatives for patients who are statin-intolerant or unresponsive, particularly those at high or very high cardiovascular risk.
• PCSK9-targeted therapies innovation spans multiple molecule classes, including IgG1/IgG2 monoclonal antibodies, siRNA, small molecules, recombinant fusion proteins, and synthetic cyclic peptides.
• In 2024, the United States accounted for the largest market size for PCSK9 targeted therapies among the 7MM, accounting for approximately USD 1,766 million, which is further expected to increase by 2034.
• Among current marketed PCSK9-targeted therapies, REPATHA, PRALUENT, and LEQVIO, monoclonal antibodies (REPATHA, PRALUENT) remain the dominant class, delivering ~58-63% LDL-C reduction with proven cardiovascular benefits but limited real-world access. LEQVIO, a siRNA-based therapy, offers ~50-52% LDL-C reduction with twice-yearly dosing and growing adoption potential, especially following its FDA label expansion for statin-intolerant patients.
• The emerging pipeline for PCSK9-targeted therapies includes several potential drugs in the late and early stages, which include Enlicitide decanoate (MK-0616), Lerodalcibep (LIB-003), Laroprovstat (AZD0780), VERVE-102, and others, which can bring about significant change in the market during the forecast period.
• The PCSK9-targeted therapies pipeline is shifting toward more convenient and disruptive modalities. Lerodalcibep, a monthly SC small-binding protein, is on track for US approval in 2025. Oral candidates MK-0616 and Laroprovstat, expected in the late 2020s, aim to eliminate injection-related barriers. Longer-term, one-time gene-editing therapy VERVE-102 could replace chronic treatment models, while preclinical oral AQR-008 targets the LDLR EGF-A domain to enable sustained LDL-C clearance.
• In the United States in 2024, approximately 1.3 million individuals experience ACS each year, encompassing both myocardial infarction and unstable angina. Additionally, around 825,508 people suffer a stroke annually in 2024.
• In 2024, the total number of familial hypercholesterolemia treatment-eligible cases for PCSK9-targeted therapies in the 7MM was 325,880. Within this population, approximately 324,816 cases were attributed to HeFH, while around 1,065 cases were associated with the much rarer HoFH.

PCSK9-targeted therapies: Disease Understanding and Treatment Algorithm

PCSK9-targeted therapies Overview

PCSK9 (Proprotein Convertase Subtilisin/Kexin Type 9) is a serine protease that regulates cholesterol levels by binding to LDL receptors on hepatocytes and promoting their degradation, which reduces the liver's ability to clear LDL-C ("bad" cholesterol) from the blood. PCSK9-targeted therapies block this process, preserving LDL receptors and enabling greater clearance of LDL-C, lowering levels by up to 50-60%. Beyond cholesterol reduction, they significantly reduce cardiovascular risk in patients with prior heart attack, stroke, or peripheral artery disease, and are used in both primary and secondary prevention. Typically given alongside statins for enhanced efficacy or as an alternative for statin-intolerant or high-risk patients, PCSK9-targeted therapies represent a key advancement in cardiovascular risk management.

PCSK9-targeted therapies: Target Population

The PCSK9-targeted therapies epidemiology chapter in the report provides historical as well as forecasted epidemiology segmented by total cases of selected indications, total treatment eligible cases of selected indications, and total statin-intolerant/uncontrolled LDL cases for PCK9-targeted therapies in the 7MM covering the United States, EU4 (Germany, France, Italy, and Spain) and the United Kingdom, and Japan from 2020 to 2034.

• Within the familial subtype, HeFH is considerably more prevalent than HoFH. In the US, there were approximately 229,500 diagnosed prevalent cases of HeFH and 861 diagnosed prevalent cases of HoFH in 2024.
• In the US, ACS has 1.3 million cases in 2024, which are expected to increase by 2034. Similarly, stroke also accounts for 825,508 cases in 2024 in the 7MM.
• In EU4 and the UK, the largest pool of treatment-eligible patients is represented by those with ASCVD in the secondary prevention setting, including individuals with prior myocardial infarction, stroke, or peripheral arterial disease.
• Within this pool, approximately 2.3 million cases were attributed to patients with peripheral arterial disease - treated pool, 624,930 cases were associated with ACS, including acute myocardial infarction and unstable angina - treated pool, and 617,280 cases were linked to stroke treated pool in 2024.
• In 2024, the total number of familial hypercholesterolemia treatment-eligible cases for PCSK9-targeted therapies in Japan was estimated at 49,848. Within this population, approximately 49,607 cases were attributed to HeFH, while around 241 cases were associated with the much rarer HoFH.
• In the 7MM, approximately 336,472 cases were associated with HeFH, and 1,043 with HoFH. These subgroups collectively represent a substantial treatment pool where conventional lipid-lowering strategies remain insufficient, highlighting the clinical need and commercial opportunity for PCSK9-targeted therapies.

PCSK9 Treatment

Multiple clinical studies have demonstrated the efficacy of PCSK9-targeted therapies across diverse high-risk patient populations. In HeFH, PCSK9-targeted therapies reduce LDL-C by ~60% in up to 80% of patients. Among individuals with ASCVD, LDL-C reductions of 60% have been reported, translating into a 20% relative risk reduction in major adverse cardiovascular events. In statin-intolerant patients, PCSK9-targeted therapies provide consistent LDL-C lowering of ~50%, offering a well-tolerated alternative to standard therapy. For very high-risk populations, such as those with prior myocardial infarction, stroke, or peripheral artery disease, PCSK9-targeted therapies have been associated with significant event reduction, including ~20% fewer myocardial infarctions, ~20% fewer ischemic strokes, and improved outcomes in secondary prevention settings. Across primary prevention cohorts, early data also indicate meaningful LDL-C lowering and risk reduction in high baseline LDL-C patients who are unable to achieve targets with statins alone. Collectively, PCSK9-targeted therapies demonstrate robust and consistent benefit across multiple subgroups, positioning them as a cornerstone of next-generation lipid management.

Marketed Drugs

PRALUENT (alirocumab): Sanofi/Regeneron Pharmaceuticals

PRALUENT is a fully humanized monoclonal antibody used for individuals with cardiovascular diseases to reduce the risk of heart attack, stroke, and certain types of chest pain conditions. It is also indicated, along with diet and statin therapy, to reduce LDL-C in adults with primary hyperlipidemia, including HeFH and HoFH. Further, it is used for children aged 8 years and older with HeFH to reduce LDL-C levels. The drug has been approved in more than 60 countries and launched in more than 30 countries, including the US, Japan, Germany, the UK, Spain, and some other countries.

REPATHA (evolocumab): Amgen

REPATHA is a human Immunoglobulin G2 (IgG2) monoclonal antibody directed against human PCSK9. REPATHA has an approximate molecular weight of 144 kDa and is produced in genetically engineered mammalian cells. It binds to PCSK9 and inhibits circulating PCSK9 from binding to the LDL receptor, preventing PCSK9-mediated LDL receptor degradation and permitting the LDL receptor to recycle back to the liver cell surface. By this inhibition, REPATHA increases the number of LDL receptors available to clear LDL from the blood, thereby lowering LDL-C levels.

Emerging Drugs

Enlicitide Decanoate: Merck Sharp & Dohme

Enlicitide decanoate is an investigational, potentially first oral PCSK9-targeted therapy designed to lower LDL-C via the same biological mechanism as currently approved monoclonal antibody injectable PCSK9-targeted therapies, but in a daily pill form. It is a novel oral macrocyclic peptide that binds to PCSK9 and inhibits the interaction of PCSK9 with LDL receptors. The global drug discovery community has voted it as their top molecule of 2023.

In June 2025, Merck announces positive top-line results from the first two Phase III CORALreef trials evaluating enlicitide decanoate for the treatment of adults with hyperlipidemia.

Lerodalcibep (LIB-003): LIB Therapeutics

Lerodalcibep is a novel, third-generation, PCSK9-targeted therapy in development to overcome the limitations of current LDL-C lowering treatments. Lerodalicibep is being developed as a convenient, small-injection volume, once-monthly dose with long-ambient stability. Combined with sustained LDL-C reductions demonstrated in clinical trials, lerodalcibep is expected to expand treatment options for the millions of patients around the world with ASCVD, and those at very high and high risk for ASCVD. Currently, the drug is being studied in Phase III of clinical trials.

LIB received a formal filing by the FDA in February with an anticipated PDUFA (Prescription Drug User Fee Act) target action date of December 12, 2025.

PCSK9-targeted therapies Market Outlook

PCSK9-targeted therapies represent a high-growth opportunity in the cardiovascular space, driven by increasing patient demand, large target population size, and a heightened sensitivity to statins, proven clinical efficacy, and a robust clinical pipeline. Although pricing pressures and competitive dynamics remain key risks, improving affordability and expanding access are expected to support sustained adoption and create significant long-term value.

The current PCSK9 market is dominated by injectable (Amgen's REPATHA). However, this dominance is expected to be challenged by Novartis's LEQVIO, which is expected to become a blockbuster in 2025. In addition to this, in the next few years launch of oral PCSK9-targeted therapies is also expected, followed by the highly anticipated approval of Verve's gene therapy. Emerging therapies (oral and gene therapy) are going to redefine cardiovascular treatment paradigms, owing to the critical advantage in a market where patients often struggle to maintain adherence to injectable therapies. Merck (enlicitide decanoate), AstraZeneca (laroprovstat), and others are developing oral PCSK9-targeted therapies; however, Merck is leading this space, as pivotal Phase III data are available for their asset. We expect oral PCSK9 therapies to expand the total PCSK9 market by two to three times.

• The market size of PCSK9-targeted therapies in the 7MM was USD 2,413 million in 2024 and is expected to grow over the forecast period (2025-2034).
• The United States is set to remain the largest and fastest-growing PCSK9-targeted therapies market, supported by relaxed access controls and early adoption of novel agents, while EU4 and the UK growth is expected to be driven by structured reimbursement frameworks. In Japan, uptake is expected to accelerate with oral launches, aligning with a strong preference for noninjectable therapies.
• REPATHA and PRALUENT are expected to experience a sales decline during the forecast period. This downward trend reflects competition from next-generation emerging therapies, including oral PCSK9-targeted therapies and pricing pressures across key markets.
