PCSK9 inhibitor treatment and outcomes
PCSK9i mAb therapy use was associated with a lower rate of ischaemic events and mortality rates vs. no PCSK9i* in a study of over 19,000 ASCVD patients without prior ischaemic events.1
Discover the findings from the methodologically advanced+ real-world OPTIMUS-CLASS study, part of the broader OPTIMUS (Outcomes and PrevenTlon Programme with PCSK9i Monoclonal Antibodies in ASCVD PopUlation without Prior ISchaemic Events) programme.1,2
Patients with ASCVD but no history of an ischaemic event who initiated a PCSK9i mAb‡ saw a:
30.9% 5-year relative risk reduction in ischaemic events and all-cause mortality vs. no PCSK9i* P<0.0001 (ARR 7.8%).1
- All patients with ASCVD are at very high or extreme risk of a potentially fatal CV event3
- LDL-C is the primary target for CV risk reduction and PCSK9 inhibitors can reduce LDL-C levels when used alone or in combination with statins3,4
- While clinical trials have established the effectiveness of PCSK9i mAbs across the different stages of ASCVD, real-world data remain limited1
- The OPTIMUS-CLASS study provides real-world evidence on the 5-year impact of PCSK9i mAbs‡ on ischaemic events and all-cause mortality in ASCVD patients without any prior ischaemic events1
The baseline characteristics for the PCSK9i mAb‡ group and no PCSK9i* group were well balanced.1

PCSK9i mAb‡ treatment was associated with a 30.9% relative reduction in the risk of nonfatal MI, nonfatal IS or all-cause mortality in ASCVD patients without a prior ischaemic event.1
The estimated 5-year event rate for the composite endpoint of nonfatal MI, nonfatal IS or all-cause mortality was significantly lower in the PCSK9i mAb‡ group vs. the no PCSK9i* group.1
The 5-year event rate was 17.5% (95% CI 15.5, 19.5) in the PCSK9i mAb‡ group (n=6,545) vs. 25.4% (95% CI 23.6, 27.1) in the no PCSK9i* group (n=13,125), resulting in a significant 30.9% relative reduction in the risk of first MACE (ARR 7.8%) (P<0.0001).1
Estimated event rates over time for the primary endpoint with parametric G-formula (ITT)1
A reduction in 5-year event rate was also seen in the PCSK9i mAb‡ group across each individual endpoint, with 28.3%, 26.4% and 28.5% RRR observed across nonfatal MI, nonfatal IS and all-cause mortality event rates, respectively, vs. the no PCSK9i* group.5

In the ITT population, patients in the PCSK9i mAb‡ group went from an LDL-C level of 117.8 mg/dL to 78.0 mg/dL at follow-up after 5 years.1 This resulted in a 39.8 mg/dL absolute reduction in LDL-C, representing a 33.8% percentage reduction.1 These findings are consistent with the CTT††, which demonstrated a strong association between RRR in MACE per 1 mmol/L reduction in LDL-C.6
Relationship between LDL-C reduction and relative risk reduction in ischaemic events compared to CTT meta-analysis1
When looking at patients who were treated with or without statins, both the with statins and without statins PCSK9i mAb‡ groups had lower cumulative event rates than their equivalent no PCSK9i* groups.5 Current study 30.9% (95% CI 22.3%, 38.1), CTT RRR 28.8% (95% CI 22.6%, 35.0%)
The falsification analysis, used to support the validity of data, found no significant difference between the PCSK9i mAb‡ and no PCSK9i* groups.1
To help determine whether the lower rate of MACE with PCSK9i mAbs‡ VS. no PCSK9i* was confounded by other factors, the study assessed whether PCSK9i mAbs‡ vs. no PCSK9i* was associated with any unexpected benefit in the falsification endpoint, defined as composite of cancer, hospitalised major bleeding or hospitalised sepsis.1 At 5 years, the incidence of the falsification endpoint was similar in the PCSK9i mAbs‡ group (9.1%) and no PCSK9i* group (10.2%), supporting the validity of the MACE data.1
Falsification analysis1
In ASCVD patients without prior ischaemic events, PCSK9i mAb‡ therapy compared with no PCSK9i* treatment was associated with a relative reduction in the risk of ischaemic events or mortality.1
*No PCSK9i represents no PCSK9 monoclonal antibodies (alirocumab or evolocumab) or PCSK9 small interfering RNA (inclisiran).1
+RWE studies can vary substantially in their methodological approaches, which may contribute to heterogeneity or unexpected findings across analyses. Ensuring that key epidemiological principles – such as appropriate time zero definition, new user design considerations, handling of open claims data, and assessment of potential time related biases – are rigorously applied remains essential to generate reliable insights. High quality RWE therefore depends on robust and methodically advanced approaches such as propensity score matching and G-computation used in the study.
