About this study

Funding Source - FDA OOPD

This study is being done to find out whether an investigational (not approved by FDA ) drug called SLx-4090 or Orlistat (FDA approved medication for weight loss) when given alone or in combination can treat the high blood fat (elevated triglycerides)levels found in the condition Type 1 Hyperlipoproteinemia (T1HLP) better or more safely than low fat diet alone, the current standard medical care.

It is also not clear whether Orlistat, that is FDA approved for weight loss, is effective in lowering blood fat levels in patients with Type 1 hyperlipoproteinemia (T1HLP). The researchers are interested in learning whether any one of these drugs when given alone or in combination is more effective and safe in treating T1HLP.

Read the detailed description

Type I hyperlipoproteinemia is a rare, autosomal recessive metabolic disorder characterized by extreme hypertriglyceridemia due to a deficiency in lipoprotein lipase or related proteins. Treatment of these patients is challenging as triglyceride-lowering medications are ineffective. A low fat diet is helpful, however, despite good dietary compliance, some patients continue to have severe hypertriglyceridemia and recurrent pancreatitis which can be life threatening. Therefore, we wish to investigate whether inducing dietary fat malabsorption or inhibiting chylomicron formation will cause further lowering of serum triglycerides (TG) beyond the effect of limiting dietary fat intake.

We will study the efficacy and safety of an inhibitor of intestinal lipase (Orlistat) and an intestinal-specific inhibitor of microsomal triglyceride transport protein (MTP) involved in the assembly and secretion of chylomicrons (SLx-4090), alone and in combination, for reducing serum triglyceride levels in patients with Type I hyperlipoproteinemia. We plan to enroll 20 patients with Type I hyperlipoproteinemia in a randomized, double-blind, placebo-controlled, cross-over trial. After a baseline evaluation, the subjects will be randomly assigned to placebo/placebo, Orlistat/placebo, SLx-4090/placebo or Orlistat/SLx-4090 for the duration of four weeks followed by a one week wash out period. During the last week of each study period, fasting blood samples will be drawn for three consecutive days for serum lipids and chemistry panel. The primary endpoint will be serum triglycerides; the secondary endpoint variables will be fasting and postprandial serum chylomicron-TG levels, postprandial serum TG levels during a meal tolerance test and retinyl palmitate levels during a meal tolerance test. Repeated measures analysis of variance will be used for statistical comparisons.

Our results may help in designing novel therapeutic approaches for patients with Type 1 hyperlipoproteinemia.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Serum Triglycerides at First Intervention Period

    Serum triglyceride level will be measured after taking each assigned intervention at first intervention period.

    Measured: 4 weeks after the assigned treatment (first intervention period)

  2. Serum Triglycerides at Second Intervention Period

    Serum triglyceride level will be measured after taking each assigned intervention at second intervention period

    Measured: 4 weeks after the assigned treatment (Second Intervention Period)

  3. Serum Triglycerides at Third Intervention Period

    Serum triglyceride level will be measured after taking each assigned intervention at intervention period

    Measured: 4 weeks after the assigned treatment (Third Intervention Period)

  4. Serum Triglycerides at Fourth Intervention Period

    Serum triglyceride level will be measured after taking each assigned intervention at fourth intervention period

    Measured: 4 weeks after the assigned treatment (Fourth Intervention Period)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Orlistat and Slx-4090 in people with Type 1 Hyperlipoproteinemia, run by University of Texas Southwestern Medical Center at 2 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 3 inclusion and 14 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: stopped early, as of the sponsor's last update on 19 Aug 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 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 19 Aug 2021). 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?

Serum Triglycerides at First Intervention Period (time frame: 4 weeks after the assigned treatment (first intervention period)). The study lists 4 primary outcomes in all. 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 19 Aug 2021.
