- ≥ 40 mIU/mL). Males will agree to use contraception and refrain from sperm donation.

Key exclusion criteria (35 listed)
- Any clinically important illness, medical/surgical procedure, or trauma within 4 weeks prior to dose administration on Day 1.
- Significant history or clinical manifestation of any metabolic, allergic, dermatological, hepatic, renal, hematological, pulmonary, cardiovascular, gastrointestinal, neurological, respiratory, endocrine, or psychiatric disorder, as determined by the Investigator (or designee).
- Obesity induced by known endocrine or genetic disorders (eg, Cushing syndrome, hypothyroidism, Prader Willi syndrome).
- Any previous surgical treatment or procedures with medical devices (such as insertion of lap band or gastric balloons) for obesity (excluding liposuction if performed > 1 year prior to Check-in).
- History of significant hypersensitivity, intolerance, or allergy to any drug compound, food, or other substance, which would increase the subject's risk of participation.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing ERX1000 in people with Obesity, run by ERX Pharmaceuticals 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 11 inclusion and 35 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 24 Oct 2023. 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. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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?
Part A (Single Dose Group A9): Incidence and severity of adverse events (AEs) (time frame: Day 1 up to end of study (Day 10)). The study lists 13 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 24 Oct 2023.
