Diabetes clinical trials at UCSF

The primary scientific question of this proposal is to investigate whether youth with T2D will wear and interact with a continuous glucose monitor (CGM) system and whether this will influence behavior and management decisions. There will be 30 participants enrolled in the study. 20 in the treatment arm and 10 in the control. The length of study participation will be 6 months for each participant.

This study aims to evaluate whether the use of an extended bolus will improve glucose control with high-fat high protein meals using a closed-loop system. The new knowledge gained from this study may provide a method to allow for the proper administration of insulin over an extended period to mitigate the risk of prolonged hyperglycemia or early hypoglycemia.

This is a randomized, parallel group, double-blind Phase 2 study with a 52-week blinded extension evaluating the safety and efficacy of 3 dose levels of frexalimab in comparison with placebo in participants with newly diagnosed T1D on insulin treatment. Study details include: Screening period: at least 3 weeks and up to 5 weeks Double-blind treatment period (104 weeks): - Main treatment period: 52 weeks - Blinded extension: 52 weeks Safety follow-up: up to 26 weeks The treatment duration will be up to 104 weeks, the total study duration will be up to 135 weeks.

Protocol Overview/Synopsis This study will be conducted at 3 sites, with each site performing a session with up to 6 participants with a lower HbA1c (<8.0%) in one of 3 age categories (26-60, 18-25, or 14-17 years) followed by a session of up to 6 additional participants with a higher HbA1c (8.0-12.0%) with the same age categories (26-60, 18-25, or 14-17 years). The trial will aim to complete a total of 36 participants: 12 total participants within each age category and 18 participants within each HbA1c category; 12 participants at each site. The study may enroll up to 70 participants to account for dropouts across the study. The study will be performed for 5 days and 4 nights at a local hotel/rental. Following the hotel session, participants will undergo a 7 day/6-night remote monitored at-home use session. The study will also conduct a two-week control period gathering data on glycemic control and insulin administration with the participants usual care therapy. Participants will be randomized 1:1, stratified by age cohort, to either group A (control period prior to AIDANET use) or group B (control period after AIDANET use).

A multi-center, placebo-controlled, double blind, 1:1:1 randomized control clinical trial testing two different JAK Inhibitors abrocitnib, ritlecitinib, and placebo in subjects with recent onset Stage 3 Type 1 Diabetes within 100 days of diagnosis.

The study is a two-arm, multicenter, double-blinded clinical trial testing sequential therapy with rituximab-pvvr followed by abatacept versus rituximab-pvvr alone in new onset T1D. The primary objective is to test whether the C-peptide response to a 2-hour mixed meal tolerance test, will be improved in participants with new onset T1D who are treated with Abatacept after Rituximab-pvvr compared to those treated with Rituximab-pvvr and placebo 24 months after enrollment.

This is a multi-center, prospective, non-interventional study that focuses on the long- term effects following participation in selected ITN new-onset Type1 Diabetes Mellitus studies with immunomodulatory agents (T1DM, T1D). This observational study will: - follow participants to determine how long they continue to produce insulin, and - will also assess how changes in the immune system over time relate to the ability to produce insulin. This information could help design better therapies for type 1 diabetes in the future.
