• Participants who have stopped using metformin and/or GLP-1/GIP have done so at least 8 weeks prior to screening.
• Participants currently taking metformin and/or GLP-1/GIP must be on a steady dose and remain on the same dose during study participation until the end of the study period.
• During continued access, starting/stopping the medication and/or modifying doses will be permitted.
• Dose changes and reasons for changes will be documented throughout the study.
• T2D: Is using non-insulin anti-hyperglycemic medication, other than metformin, GLP-1 /GIP containing medications (e.g., Mounjaro), DPP-4 Inhibitors, thiazolidinedione (TZD), or Sodium-Glucose Cotransporter 2 (SGLT2) inhibitors, in the 8 weeks prior to screening.
• Participants who have stopped using metformin, GLP-1/GIP, DPP-4 Inhibitors, TZD, or SGLT2 have done so at least 8 weeks prior to screening.
• Participants currently taking metformin, GLP-1/GIP, DPP-4 Inhibitors, TZD, or SGLT2 must be on a steady dose and remain on the same dose during study participation, until the end of the study period.
• During continued access, starting/stopping the medication and/or modifying doses will be permitted.
• Dose changes and reasons for changes will be documented throughout the study
• Is using sulfonylureas and meglitinides, e.g., repaglinide, in the 8 weeks prior to screening.
• Is using inhalable insulin in the 8 weeks prior to screening.
• Is using hydroxyurea at time of screening or plans to use it during the study
• Is participating in another pharmaceutical or device trial within 2 weeks of enrollment or anticipates participation in another trial during the course of the study.
• Is, at the discretion of the investigator, abusing drugs or alcohol.
• Is, in the opinion of the investigator, not able to perform all study procedures safely.
