IP Storage Concerns Survey

Please use the link below to report any concerns for IP storage your site may have regarding the autoinjector rollout. If you do NOT have any concerns, please complete the form noting no concerns.

  • Responses are required as soon as possible and no later than end of the day, 06Feb2026.  
  • As a reminder, IRT will begin to dispense on a 30-day supply strategy. This will result in sites receiving IP on a once-a-week basis.

Visit Guidance

If a participant visit falls out of the visit window, every effort should be made to get them back on schedule. If however, the participant is in Part A of the study, and their subsequent weekly visit is less than 5 days away, the visit should be skipped and considered a missed visit.  If the missed visit occurs at V4, V8, V12, V16, V20, V24, V28, or V32 all missed safety assessments from that visit should be collected at the subsequent visit as unscheduled procedures.

Concomitant Medication

A friendly reminder, participants should NOT be taking other weight loss medications while on the trial.  

IP Dose Modification

The release of the new protocol amendment includes updated guidance on dose modifications for two different subsets of participants.

  • Participants with a BMI <24
  • Participants with GI tolerability issues at week 10

This guidance for implementing changes in IRT is below for easy reference. Should you have a participant meeting these criteria please follow the process outlined below:
