Hydroxychloroquine (Plaquenil) Starts a Phase-II? Trial To Prevent Type-1 In Presymptomatics

This study is testing a medication, called hydroxychloroquine (HCQ) to assess safety and effectiveness to prevent individuals at risk of type 1 diabetes from progressing to type 1 diabetes.

HCQ is approved by the U.S. Food and Drug Administration as a treatment (not a cure) for malaria, lupus, and rheumatoid arthritis.  It operates through several pathways, including as an anti-inflammatory.  HCQ has been used for over 60 years, but has not previously been studied as a treatment to prevent T1D.

This Study

These researchers are recruiting 200 people who are at least 3 years old and test positive for 2 or more autoantibodies as part of TrialNet.  2/3s will get the drug and 1/3 will get a placebo and will be a control group.   The study involves 5 visits in the first 6 months, then 1 visit every 6 months for the remainder of the study (about six years).

The primary end point is the number of people who progress to having abnormal blood glucose numbers or to being diagnosed with type-1 diabetes.  (The hope is that few people getting the treatment will make this progression, as compared to the placebo group.)  The study started in Aug-2018 and they hope to finish in 2024.  Prevention studies take a long time, because the onset of type-1 takes a long time, so the researchers need to wait a long time to see if fewer people get the disease.

This trial is part of TrialNet and is being funded by JDRF.
