About this study

Official title: A 12-Week, Phase 2 Randomized, Placebo-Controlled, Double-Blind Study to Assess the Efficacy, Safety and Tolerability of Gemcabene in Subjects With Hypercholesterolemia Not Adequately Controlled on High-Intensity or Moderate-Intensity Stable Statin Therapy

The purpose of this study was to assess the efficacy, safety, and tolerability of multiple doses of gemcabene 600 mg QD compared to placebo in patients with hypercholesterolemia not adequately controlled on high-intensity or moderate-intensity stable statin therapy. Patients with HeFH, ASCVD, or otherwise uncontrolled, may be included with baseline LDL-C value ≥ 100 mg/dL. Subjects were randomized 1:1 to gemcabene 600 mg once daily (QD) or placebo.

  40. Change From Baseline in Framingham Risk Score

    Framingham Risk Score was an estimate of a participant's 10-year risk of developing cardiovascular disease which was computed using sex-specific algorithms based on total point score (range less than negative 3 [best] to greater than or equal to 14 [worst] for men; less than or equal to negative 2 [best] and greater than or equal to 17 [worst] for women) : which was derived of participant's age, systolic blood pressure , smoking status, TC, HDL-C, treatment for hypertension, and diabetes status. Reported score is a percentage. Change from baseline calculated as mean at week 12 minus mean at baseline. Negative scores indicate less risk of developing cardiovascular disease.

    Measured: Baseline, Week 12

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Gemcabene in people with Hypercholesteremia, run by NeuroBo Pharmaceuticals Inc. at 24 sites in United States.

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 0 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: finished, as of the sponsor's last update on 25 Jun 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 24 sites in United States. 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?

Yes. Results are posted in the registry (first posted 25 Jun 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percent Change From Baseline in LDL-C at Week 12 (time frame: Baseline, Week 12). 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 25 Jun 2020.
