Heart disease is the leading cause of death worldwide and in the U.S. Lowering LDL-C levels helps reduce health risks, leading to improved outcomes. Although cholesterol-lowering treatments like statins exist, many people with heart disease or those at risk struggle to achieve recommended cholesterol levels. About 1 in 200 people are born with the genetic condition called familial hypercholesterolemia (FH), which causes very high LDL-C levels from birth, requiring lifelong care.
Lerochol belongs to a group of medicines known as PCSK9 inhibitors. PCSK9 is a protein that limits how many LDL receptors your liver has, affecting the liver’s ability to remove LDL-C from the blood. By blocking PCSK9, Lerochol increases the number of LDL receptors in your liver, helping it to remove more LDL-C from your blood, leading to lower LDL-C levels.
Lerochol’s design makes it a more convenient option than other PCSK9 inhibitors, which often require more frequent dosing. It’s a small recombinant fusion protein that combines parts of a human antibody (PCSK9-binding domain) with a protein called albumin; this helps it stay in your body longer, so that you only need one injection under the skin each month. Being a self-injected medicine that remains stable at room temperature for up to three months, Lerochol offers patients the flexibility to take it anytime, anywhere.
Why Was It Approved?
Lerochol was approved by the FDA based on clinical studies, which showed that it was well tolerated and effective in lowering LDL-C levels in adults with high cholesterol levels (including those with HeFH and homozygous FH).
Lerochol’s effectiveness was tested in three clinical trials with 2,017 adults with HeFH, heart disease (Atherosclerotic Cardiovascular Disease or ASCVD), or high risk for ASCVD, all following a low-fat, low-cholesterol diet and taking the highest statin dose they could tolerate but still not reaching the recommended LDL-C levels.
The most common side effects were mild and included a stuffy nose, swelling in the arms or legs, nausea, diarrhea, and reactions at the injection site, such as itching, swelling, redness, or pain. No serious treatment-related side effects were reported in long-term studies.
No major safety concerns were noted in the studies, which helped support the FDA’s decision to approve the medicine.
What Do I Need to Know?
Lerochol is meant for adults who haven’t reached their cholesterol goals with diet, exercise, and other treatments like statins. It’s not approved for children. It is given as a 300-milligram injection under the skin once a month. You or a caregiver can inject it into your belly (at least 2 inches away from the belly button) or thigh after proper training. A caregiver or health care provider can also give it in the upper arm. Do not inject Lerochol along with other injections in the same area.
The medicine comes in a prefilled syringe and should be stored in the refrigerator. It should be allowed to warm up to room temperature for 30 minutes before it is used. If needed, you can keep it at room temperature (up to 77 F) for up to three months, as long as it stays in its original packaging. Do not freeze or shake.
If you miss a Lerochol dose, take it as soon as you remember within seven days and continue your regular schedule. If more than seven days have passed, take the dose and start a new monthly schedule from that day or check with your doctor or pharmacist if unsure. Do not stop using Lerochol without consulting your health care provider, as this can raise your cholesterol levels.
Before starting Lerochol, tell your health care provider about any medical conditions and about all medications, including over-the-counter products, vitamins, and herbal supplements, you take, so your provider can ensure that the medicine is safe for you.
Lerochol is expected to be available in the U.S. in the spring of 2026. A new autoinjector version may also be released later that year, which could make it easier to use.
