Study of the Safety and Efficacy of Intravenous Alpha-1 Antitrypsin in Type 1 Diabetes Mellitus

Open Label, Proof of Concept, Phase I/II Study of the Safety, Tolerability and Efficacy of Intravenous Alpha-1 Antitrypsin (AAT) [Trade Name Glassia™] in Type 1 Diabetes Mellitus

Alpha-1 Antitrypsin (AAT), trade name (Glassia ®), is being explored in this phase I/II trial as a potential disease modifying agent in Type 1 Diabetes Mellitus (T1DM) based on its anti-inflammatory properties. AAT is an acute stress reactant protein that increases during inflammation. In T1DM inflammation serves a major role in disease progression.

Study Overview

• Status: Completed
• Conditions: Type 1 Diabetes Mellitus
• Intervention / Treatment: Drug: Alpha-1 Antitrypsin 40mg (AAT, Glassia®); Drug: Alpha-1 Antitrypsin 60mg (AAT, Glassia®); Drug: Alpha-1 Antitrypsin 80mg (AAT, Glassia®)

Detailed Description

AAT is a protein produced by the human liver and secreted into the blood circulation. AAT, which belongs to a group of serine protease inhibitors (SERPINS) is an acute stress reactant protein that increases during stress conditions, including inflammation. AAT blocks serine proteases that enhance pro-inflammatory mediators (i.e. IL-1 alpha, IL-6, IL-8, TNFalpha) as well as induces production of anti-inflammatory mediators (i.e. IL-10 and IL-1-receptor antagonist).

In Type 1 Diabetes Mellitus (T1DM) inflammation serves a major role in disease progression. The inflammatory signature pattern in these patients appears to have been present years before clinical onset.

Although circulating levels of AAT in T1DM are normal, in majority of cases, the activity of AAT is severely compromised by non-enzymatic glycations, supporting the conclusion that serum protease inhibitory capacity is reduced in T1DM.

It has been shown in different studies, including in vivo and in vitro that AAT has a protective affect on pancreatic islets. This has been demonstrated in both decrease in progression of diabetes in the non-obese diabetic (NOD) mouse as well as during transplantation of islets which presented viability and activity (insulin production) in the presence of AAT. More specifically, islet cells are protected by human AAT from apoptosis, as shown by reduced caspase-3 activity after the addition of human AAT to islet culture media.

Based on the mentioned anti-inflammatory properties of AAT sided to in vivo and in vitro studied indicating that AAT may serve as a disease modifying agent in T1DM, the presented study is suggested.

• Planned major surgery within the study period
• Clinically significant intercurrent illnesses, including(but not limited to): cardiac, hepatic, renal,neurological, hematological, neoplastic, immunological, skeletal or other) that in the opinion of the investigator, could interfere with the safety, compliance or other aspects of this study. Patients with well-controlled, chronic diseases could be possibly included after consultation with the treating physician and the sponsor.
• Pregnant or lactating women at entry to study and those who are unwilling to agree to continue to use acceptable methods of contraception throughout the study.

• Participation in another interventional clinical trial within 30 days prior to baseline visit.
• Inability to attend scheduled clinic visits and/or comply with the study protocol.
• Any other factor that, in the opinion of the investigator, would prevent the patient form complying with the requirements of the protocol.
• Current use of any medication known to influence glucose tolerance (e.g., beta-blockers, angiotensin-converting enzyme inhibitors, interferons, quinidine anti-malarial drugs, lithium, niacin).
• Current or prior (within the last 30 days prior to screening visit) use of metformin, sulfonylureas, glinides, thiazolidinediones, exenatide, liraglutide, DPP-IV inhibitors or amylin.
