About this study

Official title: A Multicenter, Randomized, Double-Blind, Placebo-Controlled Phase 2 Clinical Study to Evaluate the Efficacy and Safety of MWX203 Injection Alone or in Combination With Inclisiran Sodium Injection in Participants With Mixed Dyslipidemia and Inadequate Lipid Control

This is a multicenter, randomized, blinded, placebo-controlled Phase 2 study designed to preliminarily evaluate the efficacy, safety, pharmacokinetic (PK), and immunogenicity profiles of MWX203 Injection alone or in combination with Inclisiran Sodium Injection in participants with mixed dyslipidemia who have inadequate lipid control despite stable statin therapy.

The study includes 5 parallel arms with a planned enrollment of 216 Chinese participants. The study drug is administered subcutaneously once every 12 weeks for a total of 2 doses. The double-blind treatment period lasts 36 weeks, and participants whose lipid levels do not return to baseline will enter a 12-week extended follow-up period. The primary endpoint is the percentage change in serum triglyceride (TG) level from baseline at Week 24.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing MWX203 and Inclisiran Sodium Injection in people with Mixed Dyslipidemia, run by Shanghai Minwei Biotechnology Co., Ltd at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 8 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Wanxiang Chen (+86 13359015677, chenwanxiang@minweibiotech.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage change in serum TG from baseline at Week 24. (time frame: Baseline, Week 24.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Sep 2026; AzTrials last refreshed its copy on 7 Nov 2026.
