Scientific title | Primary intervention with mucosal insulin for prevention of type one diabetes in infants at high genetic risk to develop diabetes |
Study acronym | Pre-POINT (Primary Oral INsulin Trial) |
Study objectives | Oral application of insulin induces a protective immune response for the purpose of vaccination in infants at high risk of developing type one diabetes mellitus (T1DM). Please note that as of 18/02/2010 this record has been extensively updated. 1. The intranasal arm of this trial has been removed. Italy and Switzerland have been removed from the countries of recruitment, and Canada has been added. 2. The overall trial start and end date were changed from 01/04/2007 and 30/09/2008 to 01/11/2008 and 30/06/2011, respectively. 3. The target number of participants has been reduced to 25. 4. The sponsor and contact information for this trial has changed. Previous sponsor: Institute for Diabetes Research at the Paediatric Clinic (Institut für Diabetesforschung an der Kinderklinik) Munich Techical University (Technische Universität München) Kölner Platz 1 Munich (München) Germany Previous contact: Prof Anette-G Ziegler On 09/07/2013 the overall trial end date was changed from 30/06/2011 to 31/12/2013. |

Health condition(s) or problem(s) studied | Type 1 diabetes-associated development of autoimmunity |
Intervention | Current information as of 18/02/2010: Active arm: insulin given orally at 2.5 mg, 7.5 mg, 22.5 mg, or 67.5 mg daily Control arm: placebo administered orally Initial information at time of registration: Active arm A: insulin given orally at 2.5 mg, 7.5 mg, 22.5 mg, or 67.5 mg daily Active arm B: insulin given intra-nasally at 0.28 mg, 0.83 mg, 2.5 mg, or 7.5 mg daily for ten days and twice weekly thereafter Control arm A: placebo administered orally Control arm B: placebo administered intra-nasally Children will be treated for the duration of the Pre-POINT study or until becoming Glutamic Acid Decarboxylase (GAD) or IA-2 auto-antibody positive or until diabetes onset. Average expected duration of treatment: 11 months (minimum three months; maximum 18 months corresponding to expected Pre-POINT study duration). |
