6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

Adverse Reactions in Adults with Primary Hypercholesterolemia Adverse Reactions in Two Pooled 52-week Controlled Trials In two pooled 52-week, double-blind, randomized, placebo-controlled trials (Trials 1 and 2), 1,229 patients received 300 mg of LEROCHOL subcutaneously every 4 weeks [see Clinical Studies ( 14 )] .

The mean age was 64 years (range 25 to 90 years), 52% were 65 years of age or older, 37% female, 79% White, 18% Black or African American, 4% Asian; 7% identified as Hispanic or Latino ethnicity.

At baseline, 9% of patients had a diagnosis of HeFH, 74% had established atherosclerotic cardiovascular disease (ASCVD), and 26% were at increased risk for ASCVD.

Adverse reactions reported in at least 2% of LEROCHOL-treated patients and more frequently than in placebo-treated patients are shown in Table 1 .

Adverse reactions led to treatment discontinuation in 4% of LEROCHOL-treated patients and placebo-treated patients.

The most frequent adverse reaction leading to treatment discontinuation was injection site reactions, with a higher frequency in the LEROCHOL-treated group compared to placebo-treated patients (1% vs.

0%).
