What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests CTX310, a new treatment for individuals with high cholesterol unresponsive to standard treatments. The goal is to assess how the body processes different doses of CTX310 through IV infusion. Participants should have struggled with high cholesterol levels despite using other medications for at least 12 weeks. This trial may suit those with persistent high cholesterol that hasn't improved with other treatments. As a Phase 1 trial, participants will be among the first to receive this new treatment, aiding researchers in understanding its effects in people.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, it mentions that participants should be refractory to standard lipid-lowering therapies, which suggests you might need to continue your current treatment.

Is there any evidence suggesting that CTX310 is likely to be safe for humans?

Research has shown that CTX310 is generally safe for people. In a previous study, participants who took CTX310 did not experience harmful reactions, even at higher doses, indicating the treatment did not cause serious medical problems.

Administered as a single intravenous (IV) infusion, the treatment has demonstrated promising safety results. Specifically, no participants experienced serious side effects in the studies reviewed. These findings suggest that CTX310 might be a safe option for individuals with high cholesterol that does not improve with other treatments.12345

Why do researchers think this study treatment might be promising?

CTX310 is unique because it is designed to lower high cholesterol through an intravenous (IV) infusion, which is different from the oral medications like statins that are typically used. Most treatments for high cholesterol work by inhibiting cholesterol production in the liver, but CTX310 may have a different mechanism of action that targets cholesterol in a novel way. Researchers are excited about CTX310 because this innovative delivery method could offer an alternative for patients who cannot tolerate oral medications or do not respond well to current therapies.

What evidence suggests that CTX310 might be an effective treatment for high cholesterol?

Research has shown that CTX310, the investigational treatment in this trial, could be promising for high cholesterol. Studies indicate that CTX310, which uses the gene-editing technology CRISPR, safely reduced LDL cholesterol (often called "bad" cholesterol) by up to 60%. It also lowered triglycerides (a type of fat in the blood) by about 55%. These improvements appeared just two weeks after a single treatment. The treatment targets a protein called ANGPTL3, which is linked to cholesterol and triglyceride levels. Although these findings are early, they suggest that CTX310 might offer a new way to manage difficult-to-control cholesterol levels.13567

Are You a Good Fit for This Trial?

This trial is for adults aged 18–75 with high cholesterol or abnormal blood fats that haven't improved despite using the strongest available treatments. Participants must have stable organ function, not be pregnant, and agree to use birth control if needed.
