DRUG TRIALS SNAPSHOT SUMMARY:

What is the drug for?

LYNKUET is a prescription medicine used to reduce moderate to severe hot flashes (also known as vasomotor symptoms or VMS) due to menopause.

How is this drug used?

LEROCHOL is a prescription medicine (proprotein convertase subtilisin kexin type 9 [PCSK9] inhibitor) that is used as an adjunct to diet and exercise to reduce low-density lipoprotein cholesterol (LDL-C) in adults with hypercholesterolemia, including heterozygous familial hypercholesterolemia (HeFH).

How is this drug used?

LEROCHOL is a subcutaneous injection that is taken once monthly.

Who participated in the clinical trials?

The FDA approved LEROCHOL based on evidence from two clinical trials of 1,844 adults with atherosclerotic cardiovascular disease (ASCVD) or at increased risk for ASCVD events (Trial 1, NCT04797247; Trial 2, NCT04806893), and a single trial of 478 patients with heterozygous familial hypercholesterolemia (HEFH) (Trial 3; NCT04797104). The trials were conducted at 65 sites in 11 countries, including the United States, Canada, Germany, Spain, India, New Zealand, United Kingdom, South Africa, Norway, Israel, and Turkey.

The benefits and side effects of LEROCHOL for patients with ASCVD or at increased for risk for ASCVD events and HeFH were evaluated in the same trials.All trials enrolled patients who were already using other treatments to lower LDL-C, including a low-fat, low-cholesterol diet and a maximally tolerated dose of statin with or without other lipid lowering medications. Patients in all three trials were randomly assigned to receive LEROCHOL or placebo every four weeks. Patients in Trials 1 and 2 received LEROCHOL or placebo for one year, and patients in Trial 3 received LEROCHOL or placebo for 24 weeks. Neither the patients nor the health care providers knew which treatment was being given.

How were the trials designed?

All trials enrolled patients who were already using other treatments to lower LDL-C, including a low-fat, low-cholesterol diet and a maximally tolerated dose of statin with or without other lipid lowering medications. Patients in all three trials were randomly assigned to receive LEROCHOL or placebo every four weeks. Patients in Trials 1 and 2 received LEROCHOL or placebo for one year, and patients in Trial 3 received LEROCHOL or placebo for 24 weeks. Neither the patients nor the health care providers knew which treatment was being given.

All three trials measured percent change in LDL-C from baseline (before treatment) to end of treatment (52 weeks for Trials 1 and 2; 24 weeks for Trial 3) and compared LEROCHOL to placebo.

How were the trials designed?

The efficacy of LEROCHOL was demonstrated in two randomized, placebo-controlled, double-blind clinical trials (Trial 1, NCT04797247; Trial 2, NCT04806893) in adult patients with ASCVD or at increased risk of ASCVD with LDL-C ≥70 mg/dL and triglyceride ≤400 mg/dL while on stable lipid-lowering oral drug therapy. Patients were stable on a low-fat, low-cholesterol diet, maximally tolerated dose of statin with or without other oral lipid modifying therapy. Patients were randomly assigned to receive doses every four weeks of LEROCHOL 300 mg (n=1,229) or placebo (n=615) via subcutaneous injection over a 52-week treatment period. The primary endpoint was percent change in LDL-C from baseline to Week 52 in patients receiving LEROCHOL compared to placebo.

The efficacy of LEROCHOL in adult patients with HEFH was demonstrated in one randomized, placebo-controlled, double-blind clinical trial (Trial 3; NCT04797104). Patients were stable on diet, maximally tolerated dose of statin, with or without other oral lipid modifying therapy. Patients were randomly assigned to receive doses every four weeks of LEROCHOL 300 mg (n=319) or placebo (n=159) via subcutaneous injection over a 24-week treatment period. The primary endpoint was percent change in LDL-C from baseline to Week 24 in patients receiving LEROCHOL compared to placebo.

Most common side effects include injection site reactions, nasopharyngitis, diarrhea, nausea, and peripheral edema.

What are the possible side effects (results of trials used to assess safety)? 

Common sides effects were nasopharyngitis and injection site reactions. Serious adverse events were generally balanced between LEROCHOL-treated patients and placebo-treated patients in Trials 1 and 2.

GLOSSARY

CLINICAL TRIAL: Voluntary research studies conducted in people and designed to answer specific questions about the safety or effectiveness of drugs, vaccines, other therapies, or new ways of using existing treatments.
COMPARATOR: A previously available treatment or placebo used in clinical trials that is compared to the actual drug being tested.
EFFICACY: How well the drug achieves the desired response when it is taken as described in a controlled clinical setting, such as during a clinical trial.
PLACEBO: An inactive substance or “sugar pill” that looks the same as, and is given the same way as, an active drug or treatment being tested. The effects of the active drug or treatment are compared to the effects of the placebo.
SUBGROUP: A subset of the population studied in a clinical trial. Demographic subsets include sex, race, and age groups.
