The NIH Awards Allele with Grant for the Development of a New Antibody Therapy for Treating Alzheimer’s Disease

SAN DIEGO–(BUSINESS WIRE)–

The National Institute on Aging of the NIH has awarded a grant to Allele Biotechnology and Pharmaceuticals (“Allele”) to develop a new antibody therapy for treating Alzheimer’s disease. Alzheimer’s disease is the most common cause of dementia, but there are currently no treatments to stop or reverse its progression.

Alongside academic collaborators, scientists at Allele have revealed a strong correlation between a previously uncharacterized target gene and Alzheimer’s disease. They discovered that expression of the gene reduces beta-amyloid production and tau phosphorylation, two components of plaque formation in Alzheimer’s disease. Furthermore, high levels of this protein in the brain can counteract loss of synapses and cognitive impairments in mice.

Allele will generate a panel of antibodies that recognize this protein with the goal of employing one of these antibodies as a therapeutic drug candidate. The antibodies’ unique size and shape allow them to pass the blood-brain barrier to reach crucial regions of the brain, and each antibody can be easily modified and engineered to heighten its therapeutic potential. Researchers at Allele hope that an antibody treatment will improve the function of its target protein in the brains of Alzheimer’s patients and ultimately reduce pathogenesis of the disease.

Recombinant antibodies represent one of the most important classes of biological therapeutics: 80% of the best selling drugs on the market are antibodies; immune checkpoint therapies and CAR-T cell therapies rely on antibodies. Continuously seeking unique antibodies against high value targets is a key focus of Allele, along with its induced pluripotent stem cell (iPSC) programs and iPSC-based drug screening projects. With the support of the new NIH grant, Allele will not only move closer to finding antibody drug candidates in fighting one of the most devastating diseases, but also generate long-needed research tools for other scientists to further study Alzheimer’s disease. For example, fusion of these antibodies to fluorescent proteins such as mNeonGreen can be used to image Alzheimer’s disease-related factors in cultured neurons, astrocytes, oligodendrocytes, or “minibrain”-like organoids derived from human iPSCs.

Allele Receives NIH Award to Fund the Development of Large-Scale Stem Cell Production

SAN DIEGO–(BUSINESS WIRE)–

The NIH’s National Heart, Lung, and Blood Institute has awarded Allele Biotechnology and Pharmaceuticals (“Allele”) a Phase 1 SBIR grant to develop a novel manufacturing system to produce stem cell-derived human tissue and cells for clinical therapy. By increasing the scale of production and reducing the cost of manufacturing, Allele is confident that this system will overcome a considerable roadblock for clinical applications of stem cells, which is to produce a sufficient amount of therapeutic material at a manageable cost.

At the core of translating this potentially game-changing technology into medically-beneficial applications is the use of induced pluripotent stem cells (iPSCs), which hold unprecedented promise of providing any type of immune-matched cells of unlimited quantity. Allele has already developed a patented method of reprogramming somatic cells into iPSCs, secured industrial licensees using this technology, and initiated cGMP procedures for clinical applications.

Further moving iPSCs into commercially viable clinical cell therapies still requires overcoming one major barrier: the prohibitive cost of manufacturing iPSC-derived cells, mostly due to the need of expensive clinical-grade growth factors and cytokines. For example, the estimated cost of the growth factors and cytokines needed to produce a typical transfusion of platelets is $87,252.

Ultimately, Allele’s goal is to create clinical-grade iPSCs and control their differentiation into specific cell types at a scale large enough to satisfy the clinical demand. “We have been diligently working on removing the use of protein factors through our own proprietary protocols to generate many clinically-relevant cell types, including beta cells, mesenchymal stem cells, neural progenitor cells, oligodendrocytes, liver, and heart cells,” said Dr. Jiwu Wang, Allele’s CEO and the Principle Investigator of the new NIH grant. “By developing a recombinant protein-independent, real-time adjusted culture system under this project, we are confident that—as many groundbreaking technologies such as genome sequencing have done—the manufacturing process will mature and the costs will come down to eventually benefit everybody.”

Allele’s plan gained trust from the NIH scientific review panel, which gave it a near-perfect score. With this funding, Allele’s researchers will move even faster towards the goal of bringing iPSC products to clinical applications. Successful efforts will also likely provide a vehicle for genome-editing technologies such as CRISPR to be delivered into patients.
