PCSK9 Inhibitors Market Summary

• PCSK9 Inhibitors Market Size in the 7MM was accounted for ~USD 2,000 Millions and the United States accounted for the highest market (~USD 900 Million) in 2023.
• PCSK9 Inhibitors Market Growth is driven by factors like increasing PCSK9 Inhibitors Prevalence of cardiovascular diseases, a growing focus on preventive healthcare, and the wider adoption of innovative therapies. Ongoing research and development efforts aimed at broadening the therapeutic applications of PCSK9 inhibitors are also anticipated to drive market expansion further. 

PCSK9 Inhibitors Market Analysis

• Proprotein convertase subtilisin Market/Kexin type 9 (PCSK9) is an enzyme that binds to low-density lipoprotein receptors (LDL receptors), which stops LDL from being removed from the blood, leading to an increase in blood levels of LDL. The PCSK9 inhibitor blocks the PCSK9 enzyme, resulting in more LDL receptors available to remove LDL from the blood, which produces a decrease in LDL blood levels. 
• PCSK9 inhibitors are recommended for patients with cardiovascular disease at very high risk with LDL-C levels remaining ≥70 mg/dL, those with severe primary hypercholesterolemia (LDL-C level ≥190 mg/dL), individuals aged 30 to 75 with heterozygous familial hypercholestrolemia (FH) and LDL-C levels of 100 mg/dL or higher, and patients aged 40 to 75 with baseline LDL-C levels of 220 mg/dL or higher. 
• Across the 7MM, an estimated 640,000 Familial Hypercholesterolemia Diagnosed Cases were reported in 2023 out of which homozygous cases were very rare.
• In 2023, Peripheral Artery Disease accounted for the highest number in the total risk factor-specific cases of PCSK9 Inhibitors in prophylactic/preventive settings in the 7MM.
• There are currently two FDA-approved monoclonal antibodies that inhibit the action of PCSK9: PRALUENT (alirocumab) and REPATHA (evolocumab). Recently the European Union and FDA have approved LEQVIO (Inclisiran) a small interfering mRNA that inhibits the intracellular synthesis of PCSK9.
• In August 2023, Merck announced the initiation of the company’s Phase III clinical program, CORALreef, for MK-0616, an investigational, oral proprotein convertase subtilisin Market/kexin type 9 (PCSK9) inhibitor, being evaluated for the treatment of adults with hypercholesterolemia.
• The PCSK9 inhibitors Pipeline is robust, with major pharmaceutical companies such as AstraZeneca, LIB Therapeutics, Merck, Amgen, and others actively developing improved treatment options. LIB’s LIB003 is anticipated to garner the highest market share in the coming decade due to its greater efficiency and only once a month dosage.
• Increasing recognition of the role of LDL cholesterol in cardiovascular disease has bolstered demand for PCSK9 inhibitors., thus resulting in substantial market growth in the upcoming time.

PCSK9 Inhibitors Treatment Market

Proprotein convertase Subtilisin Market/Kexin type 9 serine protease (PCSK9) plays a vital role in cholesterol metabolism by regulating low-density lipoprotein (LDL) receptor degradation, which reduces the clearance of circulating LDL particles. PCSK9 activity is inversely related to LDL cholesterol (LDL-C) level: Gain-of-function PCSK9 gene mutations are one cause of elevated LDL-C and cardiovascular risk in familial hypercholesterolemia (FH), whereas loss-of-function mutations cause low LDL-C and reduced risk of atherosclerotic cardiovascular disease (ASCVD).

PCSK9 inhibitor plays a vital role in cholesterol metabolism by regulating low-density lipoprotein (LDL) receptor degradation and reducing the clearance of circulating LDL particles. Hepatocytes are the predominant site for PCSK9 production, with other sites being the intestines and kidneys. PCSK9 reduces the number of LDLR in hepatocytes by promoting their metabolism and subsequent degradation, preventing it from breaking down the receptors and allowing these to continue to reduce blood cholesterol. Three classes of LDL-C-lowering medications, i.e., statins, ezetimibe, and PCSK9 inhibitors, beneficially affect cardiovascular risk and lead to a higher density of LDL receptors on the hepatocyte surface and subsequently enhance LDL uptake. 

PCSK9 Inhibitors Treatment

PCSK9 inhibitors are currently involved in the treatment of familial hypercholesterolemia patients who are intolerant to statins or have an elevated LDL-C level despite being on maximally tolerated statin therapy. The inhibitors are also approved for an established cardiovascular disease to reduce the risk of myocardial infarction, stroke, and coronary revascularization. PCSK9 can be inhibited pharmacologically by using monoclonal antibodies that bind and neutralize PCSK9 or by RNA-targeting drugs, which contain an RNA strand complementary to PCSK9 mRNA. It leads to the assembly of an RNA-induced silencing complex (RISC), which degrades PCSK9 mRNA for a prolonged period and thereby inhibits the production of PCSK9. 

PCSK9 Inhibitors Recent Developments

• In March 2025, AstraZeneca announced that positive results from the PURSUIT Phase IIb trial for AZD0780 showed a statistically significant reduction in low-density lipoprotein cholesterol (LDL-C) when added to standard statin therapy, compared to placebo. AZD0780 is an  once-daily oral PCSK9 inhibitor for patients not reaching their LDL-C lowering goal with statins.

PCSK9 Inhibitors Marketed Drugs

• PRALUENT (Alirocumab): Sanofi/Regeneron Pharmaceuticals

PRALUENT is a human monoclonal antibody that binds to proprotein convertase Subtilisin Market/Kexin type 9 (PCSK9). PCSK9 binds to the low-density lipoprotein receptors (LDLR) on the surface of hepatocytes to promote LDLR degradation within the liver. By inhibiting the binding of PCSK9 to LDLR, alirocumab increases the number of LDLRs available to clear LDL, thereby lowering LDL-C levels.

In the US, PRALUENT is approved for use as an adjunct to diet and maximally tolerated statin therapy to treat adults with Heterozygous Hypercholesterolemia (HeFH) or clinical atherosclerotic cardiovascular disease (ASCVD) who require additional lowering of LDL-C. PRALUENT has received Orphan Drug designation for the treatment of HoFH.

• REPATHA (Evolocumab/AMG 145): Amgen 

Evolocumab is a human monoclonal IgG2 directed against PCSK9, which binds to the low-density lipoprotein receptor (LDLR) on the surface of hepatocytes to promote LDLR degradation within the liver. By inhibiting the binding of PCSK9 to LDLR, evolocumab market increases the number of LDLRs available to clear LDL from the blood, thereby lowering LDL-C levels. The US FDA granted Orphan Drug designation to REPATHA for the treatment of HoFH.

PCSK9 Inhibitors Emerging Drugs

• MK-0616: Merck Sharp & Dohme

MK-0616 is Merck’s investigational PCSK9 inhibitor, which is expected to be a breakthrough, despite having competition from several approved agents that lowers elevated cholesterol levels by targeting the same protein. The drug is being studied in its Phase II (NCT05261126) trial to determine the efficacy and safety of oral MK-0616 in lowering low-density lipoprotein cholesterol (LDL-C) in participants with hypercholesterolemia and yielded a positive result and significantly reduced LDL-C compared to placebo and the placebo-adjusted reduction.

• LIB003 (Lerodalcibep): LIB Therapeutics

Lerodalcibep is a novel, third-generation, PCSK9 inhibitor in development to overcome the limitations of current low-density lipoprotein-cholesterol (LDL-C) lowering treatments, including statins and ezetimibe, to achieve lower LDL-C targets. Lerodalicibep is being developed as a convenient, small-injection volume, once-monthly dose with long-ambient stability. Currently, it is under Phase III clinical trial.
