Tirzepatide for the Treatment of Concurrent Type 1 Diabetes and Overweight or Obesity

"Tirzepatide will be self-administered subcutaneously by study participants via an injection. The drug will be taken weekly following the schedule: 4 weeks at 2.5 mg QW, 4 weeks at 5.0 mg QW, 4 weeks at 7.5 mg QW, 4 weeks at 10.0 mg QW, 4 weeks at 12.5 mg QW, 12 weeks at 15 mg QW.~Modification of study drug will be performed if the participant is experiencing significant side effects and cannot tolerate the higher dosage of the study drug. In this instance, the study drug dosage will be reduced to the previously tolerated dosage and held at this dose for a further 4 weeks. One further attempt at dose escalation will be undertaken after 4 weeks, at the discretion of the participant and the study investigator. If recurrent side effects are experienced by the participant, the study drug will be returned to the previously tolerated dosage, and the prescription continued at this dosage for the remainder of the study."
