Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.

Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This study tests an experimental oral drug, ERX1000, for weight loss in 80 adults with obesity (BMI 30-50). Participants will take the drug or a placebo daily for 24 weeks. The main goals are to check safety and see how much weight is lost. This is an early-phase trial, so the drug is not yet proven or available.

Significant cardiovascular disease including history of congestive heart failure (CHF), coronary artery disease, myocardial infarction (MI), second degree or greater heart block, prolonged time from electrocardiogram Q wave to the end of the T wave corresponding to electrical systole (QT) syndrome, or clinically significant arrhythmias. 2. Fridericia-corrected QT interval (QTcF) \>460 msec for males and QTcF \>480 msec for females pre-dose on Day 1. 3.
