Official title
Effect of Intravenous Alpha-1 Antitrypsin on Preserving Beta-cell Function in New-onset Type 1 Diabetes Mellitus (ITN041AI)- Part II
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Aralast NP (alpha-1 antitrypsin, AAT), an alpha-1 proteinase inhibitor (human), was the drug to be tested in this clinical trial. Aralast NP is an anti-inflammatory drug that affects the cells that are thought to be involved in the development of type 1 diabetes mellitus (T1DM, T1D). This study, known as RETAIN, was planned as a two-part trial to investigate the effect of Aralast NP on preserving beta cell function and to determine if the intervention would slow the progression of type 1 diabetes. Part I of this trial (NCT 01183468) was an open-label, safety and dose level study consisting of two groups. After completion of Part I, including a satisfactory safety review, enrollment in Part II was to begin. Part II was designed as a two-arm, double-blind, placebo-controlled clinical trial, and participants were to be randomly assigned to either the Aralast NP treatment or placebo group.
