Introduction
Statin therapy has dominated cholesterol management for decades, but the field continues to evolve. New medications offer different mechanisms and administration schedules. Therapies targeting lipoprotein(a)—previously untreatable—are advancing through clinical trials. Precision medicine approaches promise more individualized treatment. Understanding these developments helps patients anticipate how cardiovascular prevention may change.
This article examines emerging therapies and future directions in lipid management. While none of this information should influence current treatment decisions (which should be based on proven therapies), understanding the research landscape provides context for the evolving field.
New LDL-Lowering Approaches
What is inclisiran and how is it different from current treatments?
Inclisiran is a small interfering RNA (siRNA) that targets PCSK9 production at the genetic level. Unlike PCSK9 inhibitor antibodies (evolocumab and alirocumab) that block the PCSK9 protein after it’s made, inclisiran prevents PCSK9 from being produced in the first place by silencing the gene (Ray et al., 2020).
The practical difference is dosing frequency. Current PCSK9 inhibitors require injection every two weeks or monthly. Inclisiran requires only two injections per year (after initial loading doses). This dramatically reduces the burden of therapy and may improve adherence for patients who find frequent injections challenging.
Inclisiran achieves approximately 50 percent LDL reduction, similar to PCSK9 antibodies (Gaine et al., 2022). It is now FDA-approved for patients with atherosclerotic cardiovascular disease or familial hypercholesterolemia who need additional LDL lowering. The long-term cardiovascular outcomes trial (ORION-4) is ongoing.
Are there other new LDL-lowering drugs in development?
Several novel approaches are advancing through development. Oral PCSK9 inhibitors would provide the LDL lowering of current injectables without the injection requirement. Early-stage compounds are being studied, though none are close to approval.
Gene therapy approaches that permanently disable PCSK9 production are being explored. A single treatment could potentially provide lifelong LDL lowering, though this raises questions about irreversibility and long-term safety that will require careful evaluation.
Bempedoic acid, while already approved, represents a relatively recent addition that provides an oral non-statin option. Its outcomes trial results strengthened its position as a proven alternative for statin-intolerant patients. Combination pills pairing bempedoic acid with ezetimibe simplify regimens for patients needing multiple non-statin therapies.
Will these new treatments replace statins?
Unlikely for most patients. Statins remain effective, well-tolerated, inexpensive, and backed by decades of outcomes evidence. For the majority of patients, generic statins will continue to be first-line therapy. Cost and accessibility advantages make statins difficult to displace.
New therapies will primarily serve patients who cannot tolerate statins, need additional LDL lowering beyond statins, or have special circumstances (like familial hypercholesterolemia) requiring aggressive treatment. They expand options rather than replace the foundation.
The future likely involves layered therapy: statins for most patients, with newer agents added for those needing more aggressive LDL lowering or unable to use statins. Rather than replacement, think of new therapies as additions to the toolkit.

Lipoprotein(a) Therapies
What is Lp(a) and why does it matter?
Lipoprotein(a) is a genetically determined particle that contributes to cardiovascular risk independent of LDL cholesterol. Unlike LDL, Lp(a) levels are largely fixed by genetics and do not respond to lifestyle changes (Emdin et al., 2016). Statins do not lower Lp(a) and may slightly increase it.
Approximately 20 percent of the population has elevated Lp(a), putting them at increased cardiovascular risk that current therapies do not address (Kronenberg et al., 2022). These individuals have residual risk even when LDL is well controlled. Until recently, no effective treatment existed for elevated Lp(a).
Measuring Lp(a) helps identify this hidden risk. A patient with “normal” LDL but very high Lp(a) has different risk than one with normal levels of both. Current guidelines recommend measuring Lp(a) at least once in adults to assess this genetically determined risk factor.
What Lp(a)-lowering therapies are being developed?
Multiple RNA-based therapies targeting Lp(a) are in development (Tsimikas et al., 2021). Pelacarsen is an antisense oligonucleotide that has shown 80+ percent Lp(a) reduction in phase 2 trials (Tsimikas et al., 2020). It requires monthly subcutaneous injection and is now in a large phase 3 cardiovascular outcomes trial.
Olpasiran, an siRNA similar to inclisiran, targets Lp(a) rather than PCSK9 and achieves similar dramatic reductions with less frequent dosing (Koren et al., 2022). Other siRNA compounds are also advancing through development. The approach of silencing gene expression appears highly effective for Lp(a) lowering.
These therapies address a previously untreatable risk factor. If outcomes trials confirm that lowering Lp(a) reduces cardiovascular events, they will represent a genuine advance for the substantial population with elevated Lp(a).
When might Lp(a) therapies become available?
The critical question is whether lowering Lp(a) actually reduces cardiovascular events. Genetic evidence strongly suggests it should—people with genetically low Lp(a) have reduced cardiovascular risk (Clarke et al., 2009). But definitive proof requires outcomes trials showing that pharmacologically lowering Lp(a) translates to fewer heart attacks and strokes.
Phase 3 outcomes trials are underway for pelacarsen (expected completion 2025) and olpasiran. If these trials are positive, FDA approval could follow within a year or two of results. Negative or inconclusive results would delay or prevent approval.
Assuming positive trials, widespread availability will depend on cost and insurance coverage decisions. Initial pricing for RNA-based therapies is typically high. Access will likely be restricted to highest-risk patients initially, with broader availability developing over time as with PCSK9 inhibitors.
Precision Medicine Approaches
How might genetic testing change statin prescribing?
Pharmacogenomic testing can identify patients at higher risk for statin side effects or with variations affecting drug metabolism. The SLCO1B1 gene affects statin transport; certain variants increase side effect risk with simvastatin specifically. Genetic testing can guide statin selection and dosing for patients with relevant variants (Ference et al., 2017).
Currently, routine genetic testing before starting statins is not recommended. The cost-benefit calculation favors empirical prescribing with dose adjustment based on clinical response. Testing is most valuable for patients who have failed multiple statins due to side effects, where genetic guidance might identify better-tolerated options.
Future developments may shift this calculus. As testing costs decrease and evidence for clinical utility grows, preemptive pharmacogenomic testing (done once and applied throughout life) may become more common. This would allow upfront identification of patients needing modified approaches.
What about polygenic risk scores for cardiovascular disease?
Polygenic risk scores combine information from many genetic variants to estimate overall cardiovascular risk. These scores can identify individuals at elevated risk even when traditional risk factors appear favorable. Someone with low LDL but high genetic risk might benefit from earlier or more aggressive treatment.
The discovery of PCSK9’s role in cholesterol regulation came from studying individuals with naturally occurring mutations (Cohen et al., 2005). This genetic approach—identifying people with extreme phenotypes and studying their genes—has proven powerful for drug development and continues to yield insights.
Clinical implementation of polygenic risk scores remains limited. Questions about how to integrate them with traditional risk assessment, which populations they work best in, and how to communicate results to patients need resolution. Research is active, and clinical applications are expanding gradually.
Will treatment become more individualized in the future?
The trend is clearly toward more individualized approaches. Understanding genetic risk factors, measuring biomarkers beyond LDL (like Lp(a) and apoB), and using imaging to assess subclinical atherosclerosis all enable more precise risk stratification and treatment targeting.
Patients with high genetic risk but currently low LDL might be identified for earlier intervention. Those with low genetic risk might reasonably defer treatment that population-based guidelines would recommend. Imaging showing absence of atherosclerosis might reassure patients with borderline indications.
The challenge is implementing individualization at scale. Current healthcare systems are optimized for standardized approaches. More individualized care requires more testing, more complex decision-making, and more time. The transition will be gradual, with precision approaches initially reserved for complex or uncertain cases.

What This Means for Patients Today
Should I wait for new therapies before treating my cholesterol?
No. Current therapies are proven effective and widely available. Waiting for future treatments while untreated risk accumulates makes no sense. Cardiovascular events prevented today by current therapy cannot be prevented retroactively by future treatments.
New therapies will primarily benefit patients inadequately served by current options: those with true statin intolerance, those with elevated Lp(a), those who cannot achieve adequate LDL lowering with available medications. If you can achieve your treatment goals with current therapy, new options add little.
Think of emerging therapies as expanding options rather than replacing current ones. If current treatment works for you, continue it. If it doesn’t, new options may eventually help. But don’t forgo proven benefit today in anticipation of uncertain future alternatives.
How can I stay informed about developments?
Discuss emerging research with your physician at regular appointments. Major developments that change clinical practice will reach your healthcare team. You don’t need to track scientific literature yourself to receive up-to-date care.
Be cautious about hype. Media coverage of early-stage research often overstates implications. A promising phase 1 result is not a breakthrough available next year. Most drugs that enter development never reach approval. Maintain appropriate skepticism about dramatic claims.
The fundamentals of cardiovascular prevention—LDL lowering, blood pressure control, not smoking, healthy lifestyle—remain unchanged regardless of future developments. Focus on what you can control today while remaining open to future advances that may enhance care.
Conclusion
The lipid management field continues advancing with new therapies and approaches. Inclisiran provides PCSK9 inhibition with twice-yearly dosing. Lp(a)-lowering therapies address a previously untreatable risk factor. Precision medicine promises more individualized care. These developments expand options for patients who need them.
For most patients, these advances will complement rather than replace current therapy. Statins remain the foundation of LDL management for the foreseeable future. New therapies fill gaps for patients with special needs—statin intolerance, inadequate response, elevated Lp(a), or very high risk requiring aggressive treatment.
Stay focused on current treatment while remaining aware of future possibilities. Work with your healthcare team to optimize your care using available therapies. Future advances will build on current foundations, and patients who manage their risk factors today will be best positioned to benefit from tomorrow’s innovations.
