About this study

Official title: Central Mechanisms and Predictors of Lorcaserin-Induced Weight Loss

This two-phase study aims to explore ways to predict who will respond well to the weight loss drug lorcaserin and to understand the mechanisms that develop which limit drug efficacy. Subjects will be recruited for a 5-week crossover study (phase 1) with lorcaserin and placebo followed by treatment with lorcaserin for 24 weeks (phase 2).

Read the detailed description

In phase 1, at Weeks 1 and 5, participants will take the weight loss drug lorcaserin or placebo for 7 days. At Week 5 participants will receive whichever treatment they did not receive at Week 1. At the end of Weeks 1 and 5, participants will have a lumbar puncture (spinal tap) to collect cerebrospinal fluid (CSF) for neuropeptide and hormone analyses, including proopiomelanocortin (POMC), Agouti-related protein (AgRP) and cortisol. Blood will also be obtained for neuropeptide and hormone analyses. Breakfast will be served to participants who will then complete an eating behavior profile. A laboratory test meal will be performed 4h after breakfast.

After completing both the 7 day lorcaserin and placebo studies, participants will then continue on Phase 2 of the study, which includes treatment with lorcaserin for 24 weeks. Subjects will receive nutritional counseling to reduce their daily caloric intake to 600 kcal below their calculated caloric requirement and will be encourage to exercise moderately for 30 minutes daily. Participants will visit the clinic monthly during the 24 week study period for nutritional counseling, review of food diaries, vital signs and safely labs. Blood will also be obtained for neuropeptide peptide and hormone analyses. At the end of the 24 week period subjects will come for a final study visit, including a lumbar puncture, blood sample, breakfast, an eating behavior profile and a test meal.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • BelviqDrug

    Also called Lorcaserin

    Belviq is an oral drug

  • PlaceboDrug

    The placebo is made to mimic Belviq, but does not contain any active drug

What is being measured

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

  1. Mean Differences in Food Intake During a Laboratory Test Meal After Lorcaserin for One Week Compared to Placebo

    This is designed to measure food Intake (average calories consumed during test meal), in order to determine if long-term lorcaserin induced weight loss is predicted by the short-term differences in calories consumed during the test meal.

    Measured: First test meal and follow-up test meal (approximately up to 5 weeks)

  2. Mean Differences in POMC Concentrations (Fmol/ml) in CSF After Lorcaserin for One Week Compared to Placebo

    This is designed to measure mean CSF proopiomelanocortin (POMC) concentrations (fmol/ml), in order to determine if long-term lorcaserin induced weight loss can be predicted by differences in CSF POMC concentrations.

    Measured: Baseline, up to 5 weeks

Secondary outcomes (5)
  1. CSF Concentrations of ß-endorphin

    Mean differences in levels of ß-endorphin, a POMC-derived peptide, in CSF after lorcaserin for one week compared to placebo in order to determine if long-term lorcaserin induced weight loss can be predicted using short-term differences in CSF concentrations of ß-endorphin.

    Measured: Baseline, up to 5 weeks

  2. Mean Differences in AgRP Concentrations (pg/ml) in CSF After Lorcaserin for One Week Compared to Placebo

    This is designed to measure mean mean Agouti-related protein (AgRP) concentrations (pg/ml) in CSF in blood in order to determine if long-term lorcaserin induced weight loss can be predicted by short-term differences in AgRP concentrations.

    Measured: Baseline, up to 5 weeks

  3. Mean Differences in AgRP Concentrations (Fmol/ml) in Blood After Lorcaserin for One Week Compared to Placebo

    This is designed to measure mean Agouti-related protein (AgRP) concentrations (fmol/ml) in blood in order to determine if long-term lorcaserin induced weight loss can be predicted by short-term differences in AgRP concentrations.

    Measured: Baseline, up to 5 weeks

  4. Mean Differences in Cortisol Concentrations (ng/ml) in CSF After Lorcaserin for One Week Compared to Placebo

    This is designed to measure mean Cortisol concentrations (ng/ml) in CSF in order to determine if long-term lorcaserin induced weight loss can be predicted by short-term differences in cortisol concentrations.

    Measured: Baseline, up to 5 weeks

  5. Insulin Level

    This is designed to determine effects of lorcaserin on glucose homeostasis by measuring changes in insulin levels after 1 week of lorcaserin versus placebo.

    Measured: Changes in fasting serum insulin after 1 week of lorcaserin compared to placebo.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Belviq in people with Overweight and Obesity, run by Columbia University at 1 site 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 1 inclusion and 13 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 27 Mar 2024. 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 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. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 23 Sep 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?

Mean Differences in Food Intake During a Laboratory Test Meal After Lorcaserin for One Week Compared to Placebo (time frame: First test meal and follow-up test meal (approximately up to 5 weeks)). The study lists 2 primary outcomes in all. 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 NCT03353220, 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 27 Mar 2024.
