A Study of GNTI-122 in Adults Recently Diagnosed With T1D
This is a 78-week single arm, multi-center, Phase 1 study to evaluate the safety, tolerability, cellular kinetics, and biomarker changes in C-peptide over time of GNTI-122, an investigational cell therapy manufactured from a participant's own blood cells in adult participants with recently diagnosed T1D. After assessment of eligibility, participants who qualify for the study will be enrolled sequentially in 1 of 3 cohorts. Cohort 1 participants (n=3) receive a low dose of GNTI-122 . Cohort 2 participants (n=3) receive a high dose of GNTI-122. Cohort 3 participants (n=10) receive a high dose of GNTI-122 in combination with rapamycin. Participants are followed for 78 weeks after the administration of GNTI-122 during which safety and efficacy assessments are made, including vital signs, ECG, physical exam, clinical labs, and monitoring of adverse events and concomitant medications. Disease markers (e.g., MMTT-stimulated C-peptide, HbA1c) and pharmacodynamic activity (e.g., lymphocyte subsets and phenotypes, effector T cell responses to islet antigens ex vivo, T1D autoantibodies) will be monitored serially throughout the study. The study will include sentinel dosing and a Safety Review Committee to ensure participant safety. Visit https://www.polarisstudy.com to learn more!
