Investigational / China-only dosing: once-weekly subcutaneous injection, dose-escalated over several weeks. Trial maintenance doses studied were 4 mg, 6 mg, and 9 mg once weekly (lower doses used during titration to limit GI effects). There is no FDA-approved regimen.
Any time of day
Once-weekly subcutaneous injection (investigational; China-approved as Xinermei)
Investigational — NO approved dose. Phase-2 trials used once-weekly subcutaneous injection with stepwise escalation up to 4.8-6.0 mg maintenance. There is no approved regimen; do not self-dose an unapproved drug.
