Precision T1D Platform - New Therapies for Cardio-Renal Complications

This is a multicenter, open label pilot platform study to evaluate the impact of allocating patients with T1D and early signs of HF/DKD to targeted therapies based on their disease pathway activation signatures. The hypothesis is that stratifying T1D patients by molecularly-defined endophenotypes enables the use of targeted therapies that can more effectively prevent or slow cardio-renal complications. There is no randomized allocation to treatment arms; rather, the eligible participant's clinical and biomarker data will be reviewed by the Molecular T1D Board which will adjudicate each participant to a treatment arm based on their based on their disease pathway activation signatures. Activation of different treatment arms may be initiated at different time points during the study. The following sections describe the master protocol, outlining the requirements across all treatment arms, including the study-wide inclusion and exclusion criteria and study-wide procedures. Appendix A outlines any treatment arm/investigational agent specific information, including defining additional treatment-specific eligibility criteria and required study procedures. The study schema can be found in Section 1.2 and the Schedule of Activities (SoA) in Section 1.3. Potential participants will undergo a two-part consent and screening process. The initial consent and screening visit will be limited to activities necessary for assessment by the Molecular T1D Board. Following review by the Molecular T1D Board, participants will be adjudicated to one treatment arm. At this time, participants will undergo the second consent and screening step, which will include information about specific requirements for their assigned investigational arm and, if in agreement, a complete eligibility assessment via a full screening visit. If the participant is deemed eligible, they will be notified and investigational product will be mailed to them directly. The screening visit results will also serve as the baseline results provided the first dose of study drug is taken within 14 (target) to 21 (limit) days of the screening visit. If more than 21 days, a retest of all laboratory measures will be performed. Participants will receive open label treatment for 26 weeks, with planned study visits at weeks 2, 6, 12, 26, and 30. The total study duration of participation will be up to 36 weeks, inclusive of the screening period. Active study participation will conclude at Week 30 visit. Following completion of active study participation, participants will enter a passive follow-up period during which the study team may collect information on vital status, survival, hospitalizations, and other relevant clinical outcomes through review of medical records and other authorized data sources for up to 12 months after study participation ended. No additional protocol-required visits, procedures, or interventions will be conducted during the passive follow-up period. Participants will be enrolled in this study at Oregon Health \& Science University and the University of Michigan. The currently planned number of study arms is three, with 15-19 participants enrolled in each arm. The study sponsors will have the option to increase the number of study arms and potential targeted therapies, which would be documented in the appendices and this master protocol.
