Significant results has been shown in a genetically predefined subgroup in the Company’s European Phase IIb trial DIAGNODE-2, where the diabetes vaccine is administered directly into a lymph node in children and young adults with newly diagnosed type 1 diabetes. GAD/alum vaccine in LADA and new-onset type 1 diabetes. Clinical trials of GAD/alum vaccination were first conducted in individuals with LADA, a slowly progressing form of type 1 diabetes . Subjects received placebo or GAD/alum (4, 20, 100, or 500 μg) subcutaneously, twice. Only the 500-μg dose boosted GAD autoantibody levels.
We have previously shown that GAD-alum has a specific immunomodulatory effect, indicated by enhanced GAD autoantibodies (GADA) and specific in vitro cytokine secretion upon GAD 65 stimulation [15, 16]. Thus, in hydroxide (G AD-alum) is an anti gen-specif ic immunother apy intended to induce specific i mmunological tolerance to preserve the pa ncreatic beta ce lls that are target ed in type 1 diabetes by A European Phase III trial of GAD formulated with aluminium hydroxide (GAD-alum) failed to reach its primary endpoint (preservation of stimulated C-peptide secretion from baseline to 15 months in type 1 diabetes patients), but subgroup analysis showed a clinical effect when participants from Nordic countries were excluded, raising concern as to whether the mass vaccination of the Swedish and Finnish populations with the Pandemrix influenza vaccine could have influenced the study outcomes. Glutamic acid decarboxylase (GAD)-alum (Diamyd (®), Diamyd Medical, Stockholm, Sweden) is an adjuvant-formulated vaccine incorporating recombinant human GAD65, the specific isoform of GAD Aims/hypothesis: GAD is a major target of the autoimmune response that occurs in type 1 diabetes mellitus. Randomised controlled clinical trials of a GAD + alum vaccine in human participants have so far given conflicting results. De första immunologiska resultaten från DIAGNODE-2 visar att immunsvaret skiljer sig signifikant mellan genetiskt definierade patientgrupper för flera immunologiska parametrar efter behandling med diabetesvaccinet Diamyd ® (GAD-alum). In the group that received two doses of GAD-alum, levels of several GAD65-induced cytokines were higher in participants who received the H1N1 vaccination and the first GAD-alum injection at least 150 days apart, and the change in fasting and stimulated C-peptide at 15 months was associated with the relative time between vaccines.

"These results support decades of research on GAD-alum as a safe, specific and efficacious treatment for type 1 diabetes, says Johnny Ludvigsson, Professor at Linköping University. Several trials betted on GAD65 as key Ag and on different routes: Dyamid, a GAD-Alum vaccine, was administered subcutaneous in recent onset T1D (15, 16) and in adults with latent autoimmune diabetes (LADA) without achievement of clinically desirable results . Combination of Dyamid with vitamin D in LADA is currently being tested in a Phase II trial (NCT04262479). The GACVS reviewed 2 published papers alleging that aluminium in vaccines is associated with autism spectrum disorders 3, 4 and the evidence generated from quantitative risk assessment by a US FDA pharmacokinetic model of aluminium-containing vaccines. GACVS considers that these 2 studies 3, 4 are seriously flawed. The core argument made in

Although GAD vaccine was ineffective in recent onset diabetes,
Type 1 diabetes mellitus (T1D) is characterized by a heightened antibody (Ab) response to pancreatic islet self-antigens, which is a biomarker of progressive islet pathology. We recently identified a novel antibody to clade B serpin that reduces islet-associated T cell accumulation and is linked to the delayed onset of T1D. As natural immunity to clade B arises early in life, we hypothesized

The results show, in line with comprehensive insights from previous trials and scientific publications, that the diabetes vaccine Diamyd ® (GAD-alum) has a positive and significant disease-modifying effect on the preservation of endogenous insulin production compared to placebo in a genetically predefined patient group.
History of Changes for Study: NCT00723411 - Clinical Trials
Combination of Dyamid with vitamin D in LADA is currently being tested in a Phase II Protocol Description. The goal of this multi-center TrialNet study is to learn if recombinant human glutamic acid decarboxylase (rhGAD65) formulated in alum (GAD-alum) can help people with newly diagnosed type 1 diabetes by delaying or stopping further destruction of insulin-producing beta cells. This therapeutic pathway provides a safe treatment to preserve beta cell function in new-onset diabetic individuals with the GAD-Alum vaccine being the most extensively studied therapy. Insulin is being used in many forms to prevent diabetes and stop the underlying autoimmune process. TrialNet is planning a GAD-Alum Prevention Study, with a primary objective to determine GAD-Alum vaccine will prevent or delay the development of clinical T1D in non-diabetic relatives of patients with T1D, age 3–45, who are positive for GAD autoantibodies but not insulin autoantibodies. While NOD studies and smaller early clinical trials showed promise with the GAD-alum vaccine, a phase 2 trial and an industry sponsored phase 3 trial did not show effects on the rate of β-cell decline compared to placebo groups(36, 37).
GAD-Alum is Recombinant human (rhGAD65) and is used as an antigen-specific immune modulator. Previous studies have shown that it may slow or prevent autoimmune destruction of pancreatic islet cells by introducing "immune tolerance". By administering excess autoantigen, the body may stop its attack on its own cells that produce insulin.
