Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of MWX205

Starting soon · Phase 1 · Has a placebo group

Conditions studied: Dyslipidemias

In brief

This study is being done to test a new injection called MWX205 in people with high cholesterol or fat levels in the blood (dyslipidemia). Researchers will check if a single dose of MWX205 is safe and how the body reacts to it. They will also measure how quickly the drug enters the bloodstream and how long it stays in the body, and compare it with a placebo (inactive treatment). The study will help decide the right dose and understand how this medicine could be used in future treatments. The main questions this study aims to answer are: 1. Is MWX205 safe after a single dose? 2. How does the body process MWX205? 3. Does MWX205 show any effect on the body related to cholesterol levels?

You may qualify if…

• Adult participants with dyslipidemia will be enrolled in this study.
• The absence of clinically significant illness and surgery within 4 weeks prior to study drug administration.
• Participants must have fasting triglycerides greater than or equal to 150 mg/dL (1.7 mmol/L) and less than 500 mg/dL (5.7 mmol/L), and LDL-C greater than or equal to 70 mg/dL (1.8 mmol/L) at pre-screening and confirmation within 7 days before randomization.

• Females of childbearing potential and males who are not surgically sterile (> 90 days since vasectomy with no viable sperm) will agree to use contraception from Screening until 6 months after the administration, OR females of non-reproductive potential

You may not qualify if…

• Positive pregnancy test or lactating female participant.
• Systolic BP lower than 90 or over 140 mmHg, diastolic BP lower than 40 or over 90 mmHg, HR less than 40 or over 100 bpm at screening.

• History of intolerance to SC injection or relevant abdominal scarring (surgical, burns, etc.), or any skin conditions, including infections or open wounds, or dermatitis at the injection site that could interfere with the evaluation of injection reaction.
• Have taken any prescription medications that are specifically indicated for lowering serum TGs (e.g., fibric acid derivatives, niacin, and omega-3 fatty acids [>1 g/day]) or medications that interfere with absorption of dietary cholesterol or fats (e.g., bile acid sequestrants, orlistat) within 2 months prior to screening.
• Have received treatment with any liver-targeted siRNA therapy or ASO (Antisense Oligonucleotide) within12 months prior to screening.
• Use of ANGPTL3 or PCSK9-inhibiting monoclonal antibodies within 90 days prior to screening.
• Use of systemic glucocorticoid therapy for more than 14 consecutive days in the past year, or any glucocorticoid therapy (excluding topical, intra-ocular, intra-articular, intranasal, or inhaled preparations) within 1 month before screening.
