Brief summary
Phase III study to test the hypothesis that treatment with pelacarsen (TQJ230) 80 mg Q4W compared to placebo significantly reduces the rate of lipoprotein apheresis in patients with hyperlipoproteinemia (a) and established cardiovascular disease currently undergoing lipoprotein apheresis in Germany on a weekly schedule.
Detailed description
Lipoprotein apheresis to date is the only approved therapeutic option for cardiovascular (CV) risk reduction in patients with severely elevated Lp(a) levels in Germany. Lipoprotein apheresis is an expensive, burdensome, and time-consuming procedure. The current study (CTQJ230A12302) investigated if treatment with pelacarsen (TQJ230) 80 mg Q4W vs placebo reduces the rate of lipoprotein apheresis in patients with hyperlipoproteinemia(a) and established CV disease

Eligibility
Inclusion criteria
* Patients currently undergoing lipoprotein apheresis for isolated Lp(a) on a weekly schedule in Germany for ≥ 12 months prior to screening with at least 40 sessions within the past 52 weeks prior to randomization * Lipoprotein(a) (Lp(a))\> 60 mg/dL at screening * Spontaneous prior myocardial infarction (MI): ≥ 3 months from screening visit to ≤ 10 years prior to the screening visit, and/or * Ischemic stroke: ≥ 3 months from screening visit to ≤ 10 years prior to the screening visit, and/or * Clinically significant symptomatic peripheral artery disease (PAD) * Clinically significant symptomatic coronary artery disease (PAD)
Exclusion criteria
* Uncontrolled hypertension * Heart failure New York Heart Association (NYHA) class IV * History of malignancy of any organ system * History of hemorrhagic stroke or other major bleeding * Platelet count \<140,000 per mm3 at screening * Active liver disease or hepatic dysfunction * Significant kidney disease * Pregnant or nursing women
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Rate of Lipoprotein Apheresis Sessions Performed Over 52 Weeks Normalized to the Weekly Lipoprotein Apheresis Schedule | Up to Week 52 | Rate (proportion) of apheresis sessions was calculated as the number of actual lipoprotein apheresis (LA) sessions received, divided by the number of planned LA sessions during the 52-week period, which is 52 for patients who completed all study visits, or pro-rated for those who discontinued early. This rate could range from 0 to 1, with 0 indicating that the patient had skipped all planned LA sessions, and 1 indicating that the patient had received all planned sessions. Multiple imputation for missing Lp(a) data was performed, and missing apheresis data was imputed. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Time to Lipoprotein Apheresis Avoidance | From randomization up to Week 52 | Lipoprotein apheresis avoidance is defined as at least 24 consecutive weeks of no lipoprotein apheresis until end of study. |
| Number of Participants With Total Lipoprotein Apheresis Avoidance From Week 12 to Week 52 | Week 12 up to Week 52 | Total lipoprotein apheresis avoidance is defined as no apheresis performed from Week 12 to Week 52. |
| Change From Baseline to Week 52 in the Log-transformed Lp(a) Reported as mg/dL | Baseline, week 52 | Week 52 / Baseline ratio in Lp(a) of pelacarsen (TQJ230) vs placebo reported as particle mass (mg/dL). Baseline Lp(a) was defined as the last non-missing pre-lipoprotein apheresis assessment prior to the first dose of randomized study drug. |
| Change From Baseline to Week 52 in the Log-transformed Lp(a) Reported as Nmol/L | Baseline, week 52 | Week 52 / Baseline ratio in Lp(a) of pelacarsen (TQJ230) vs placebo reported as molar concentration (nmol/L). Baseline Lp(a) was defined as the last non-missing pre-lipoprotein apheresis assessment prior to the first dose of randomized study drug. |
