About this study
Official title: An Open-label Dose Finding Study Followed by a Parallel Group, Randomized, Double-blind Study to Evaluate the Safety, Tolerability and Pharmacodynamics of 12 Week BGS649 Treatment in Obese, Hypogonadotropic Hypogonadal Men

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Investigational new drug company code: BGS649Drug
PlaceboDrug
| Study group | Role | What they receive |
|---|---|---|
| BGS649 (Part 1) | Experimental | BGS649 1mg and 0.1mg in hard gelatin capsules. In part 1 there was individualised dosing to titrate the subject's testosterone into the normal range. If the dose was lower than 0.1mg then specific instructions for dilution of an oral solution of BGS649 were provided. Receives: Drug: Investigational new drug company code: BGS649 |
| Placebo to BGS649 (Part 2) | Placebo comparator | Matching placebo to BGS649 (0.3 and 0.1mg). 0.3mg placebo capsule given on Day 1 and 0.1mg placebo capsule on other treatment visits (week 1 to 11). Receives: Drug: Placebo |
| BGS649 (Part 2) | Experimental | 0.3 or 0.1mg hard gelatin capsules of BGS649 given orally. 0.3mg on Day 1 and 0.1 on all other treatment visits (week 1 to 11). Receives: Drug: Investigational new drug company code: BGS649 |
What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of Patients Achieving Normal Testosterone Levels
Percentage of patients achieving normal testosterone (2.50 - 9.50 ng/mL) levels at Week 4 and Week 12
Measured: At Week 4 and 12
Part 2: Change From Baseline at Homeostatic Model Assessment of Insulin Resistance (HOMA-IR & QUICKI Scores) at Week 4 and 12
Pharmacodynamic change from baseline in HOMA-IR. Score at week 4 and week 12 as an assessment of insulin resistance. Low score representing high insulin sensitivity and a high score representing low insulin sensitivity or insulin resistance. HOMA-IR is a ration of Fasting insulin (mIU/L) : Fasting glucose (mmol). Pharmacodynamic change in QUICKI score at week 4 and week 12 as an assessment of insulin resistance. The QUICKI scale is a log score and a high score representing high insulin sensitivity and low score indicating low insulin sensitivity. Patients with a score below 0.3 are considered diabetic. Week 12 data is missing because there were inaccuracies in dosing of patients and so the study was terminated, only safety data was collected.
Measured: Baseline, Week 4 and Week 12
Secondary outcomes (4)
Part 2: Area Under the Concentration-time Curve From Time Zero to Time 't' (AUC0-168)
PK sampling was performed at 0hr (pre-dose), 1 hr, 8 hr, 24 hr, 72 hr, and 168 hr on the following occasions Week 1, Week 4 and week 11. The AUC 0-168 measures the amount of drug within the subjects blood over the 168h post-dosing at these timepoints.
Measured: 11 weeks
Part 2: Pharmacokinetics of BGS649: Maximum (Peak) Observed Blood Drug Concentration After Single Dose Administration (Cmax)
PK sampling was performed at 0hr (pre-dose), 1 hr, 8 hr, 24 hr, 72 hr, and 168 hr on the following occasions Week 1, Week 4 and week 11.
Measured: Week 1 to Week 11
Part 2: Pharmacokinetics of BGS649: Time to Reach Maximum (Peak) Blood Drug Concentration After Single Dose Administration (Tmax)
PK sampling was performed at 0hr (pre-dose), 1 hr, 8 hr, 24 hr, 72 hr, and 168 hr on the following occasions Week 1, Week 4 and week 11.
Measured: Week 1 to Week 11
PK of BGS649 Elimination Half-life Associated With the Terminal Slope of a Semi Logarithmic Concentration-time Curve (T1/2)
PK sampling was performed at 0hr (pre-dose), 1 hr, 8 hr, 24 hr, 72 hr, and 168 hr on the following occasions Week 1, Week 4 and week 11.
Measured: Week 1 to Week 11

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Investigational new drug company code: BGS649 in people with Obese Hypogonadotropic Hypogonadism, run by Mereo BioPharma at 5 sites in 2 countries.
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 12 inclusion and 3 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 8 Oct 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 5 sites in United States, Canada. 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 8 Oct 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?
Percentage of Patients Achieving Normal Testosterone Levels (time frame: At Week 4 and 12). 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?
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 Oct 2020; AzTrials last refreshed its copy on 8 Nov 2026.
