    Advancing Monogenic Diabetes Research and Clinical Care by Creating a Data Commons: The Precision Diabetes Consortium (PREDICT)
    (Sage, 2025-01-09) McCullough, Michael E.; Letourneau-Freiberg, Lisa R.; Naylor, Rochelle N.; Greeley, Siri Atma W.; Broome, David T.; Tosur, Mustafa; Kreienkamp, Raymond J.; Cobry, Erin; Rasouli, Neda; Pollin, Toni I.; Udler, Miriam S.; Billings, Liana K.; Desouza, Cyrus; Evans-Molina, Carmella; Birz, Suzi; Furner, Brian; Watkins, Michael; Ott, Kaitlyn; Volchenboum, Samuel L.; Philipson, Louis H.; Pediatrics, School of Medicine
    Monogenic diabetes mellitus (MDM) is a group of relatively rare disorders caused by pathogenic variants in key genes that result in hyperglycemia. Lack of identified cases, along with absent data standards, and limited collaboration across institutions have hindered research progress. To address this, the UChicago Monogenic Diabetes Registry (UCMDMR) and UChicago Data for the Common Good (D4CG) created a national consortium of MDM research institutions called the PREcision DIabetes ConsorTium (PREDICT). Following the D4CG model, PREDICT has successfully established a multicenter MDM data commons. PREDICT has created a consensus data dictionary that will be utilized to address critical gaps in understanding of these rare types of diabetes. This approach may be useful for other rare conditions that would benefit from access to harmonized pooled data.

    Safety and prescribing recommendations for verapamil in newly diagnosed pediatric type 1 diabetes (T1D): The CLVer experience
    (Elsevier, 2024-05-18) Ekhlaspour, Laya; Buckingham, Bruce; Bauza, Colleen; Clements, Mark; Forlenza, Gregory P.; Neyman, Anna; Norlander, Lisa; Schamberger, Marcus; Sherr, Jennifer L.; Bailey, Ryan; Beck, Roy W.; Kollman, Craig; Beasley, Shannon; Cobry, Erin; DiMeglio, Linda A.; Paprocki, Emily; Van Name, Michelle; Moran, Antoinette; CLVer Study Group; Pediatrics, School of Medicine
    Objectives: To report the safety and side effects associated with taking verapamil for beta-cell preservation in children with newly-diagnosed T1D. Research design and methods: Eighty-eight participants aged 8.5 to 17.9 years weighing ≥ 30 kg were randomly assigned to verapamil (N = 47) or placebo (N = 41) within 31 days of T1D diagnosis and followed for 12 months from diagnosis, main CLVer study. Drug dosing was weight-based with incremental increases to full dosage. Side effect monitoring included serial measurements of pulse, blood pressure, liver enzymes, and electrocardiograms (ECGs). At study end, participants were enrolled in an observational extension study (CLVerEx), which is ongoing. No study drug is provided during the extension, but participants may use verapamil if prescribed by their diabetes care team. Results: Overall rates of adverse events were low and comparable between verapamil and placebo groups. There was no difference in the frequency of liver function abnormalities. Three CLVer participants reduced or discontinued medication due to asymptomatic ECG changes. One CLVerEx participant (18 years old), treated with placebo during CLVer, who had not had a monitoring ECG, experienced complete AV block with a severe hypotensive episode 6 weeks after reaching his maximum verapamil dose following an inadvertent double dose on the day of the event. Conclusions: The use of verapamil in youth newly-diagnosed with T1D appears generally safe and well tolerated with appropriate monitoring. We strongly recommend monitoring for potential side effects including an ECG at screening and an additional ECG once full dosage is reached.
