About this study

Official title: A Phase 2, Single-Arm, Open-Label Study to Evaluate the Safety and Tolerability of PBI-4050 and of Its Effects on the Inflammatory, Fibrosis, Diabetes and Obesity Biomarkers in Subjects With Alström Syndrome

This is a Phase 2, single-centre, single-arm, open-label study of the safety, tolerability, and effects on biomarkers of PBI-4050 in subjects with Alström syndrome for a treatment duration of 24 weeks.

Subjects who complete the initial 24 weeks of treatment may continue treatment for an additional 36 or 48 weeks, provided the subject signs informed consent.

Read the detailed description

This is a Phase 2, single-centre, single-arm, open-label study of the safety, tolerability, and effects on biomarkers of PBI-4050 in subjects with Alström syndrome. Approximately 18 subjects will be enrolled. The duration of study participation is approximately 35 weeks for each subject and comprises of 9 on site visits and telephone contacts in between visits.

Subjects who complete the initial 24 weeks of treatment may continue treatment for an additional 36 or 48 weeks (Extension Period [EP]), provided the subject signs informed consent. The extension period includes a further 3 on site visits and telephone contacts in between visits. The total duration of the study participation is extended to approximately 71 or 83 weeks. The Data Safety Monitoring Board (DSMB) will determine if the safety data continue to support treatment for an additional 36 or 48 weeks.

At the completion of the EP End of Treatment, subjects will be allowed to enrol in the Alström Rollover Study PBI-4050-CT-9-10 and continue ongoing study medication without any break in treatment.

What is being measured

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

  1. Description and number of abnormal laboratory values and adverse events that are related to treatment.

    Measured: Primary on 24 weeks; Final on all data (including Extension Period)

Secondary outcomes (4)
  1. Change from baseline in metabolic syndrome parameters over time.

    Change from baseline in fasting plasma glucose over time. Change from baseline in fasting plasma insulin over time. Change from baseline in glycated hemoglobin (HbA1c) over time. Change from baseline in Homeostasis Model Assessment for steady state beta cell function (HOMA-B) and insulin sensitivity (HOMA-S) over time.

    Measured: 24 weeks and end of Extension Period

  2. Change from baseline in biomarkers in blood and urine over time

    Percentage of reduction and/or increase of level of biomarkers

    Measured: 24 weeks and end of Extension Phase

  3. Change from baseline in cardiac function parameter: NT-proBNP

    Measured: 24 weeks and end of Extension Phase

  4. Change from baseline of antidiabetic treatment

    Dosing change, new medication added or treatment discontinuation

    Measured: 24 weeks and end of Extension Phase

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing PBI-4050 in people with Inflammation and Fibrosis and Diabetes, run by Liminal BioSciences Ltd. at 1 site in United Kingdom.

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 10 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 29 Aug 2018. 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 United Kingdom. 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. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Description and number of abnormal laboratory values and adverse events that are related to treatment. (time frame: Primary on 24 weeks; Final on all data (including Extension Period)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02739217, which also lists 1 linked publication.

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 29 Aug 2018.
