Cell-based therapies have already shown tremendous promise in terms of treating leukemia, lymphoma, and certain types of blindness. These therapies are now expanding significantly into the treatment of chronic, non-cancerous diseases, such as heart disease, diabetes, and neuro-degenerative disorders.
A New Approach To Treat
Diabetes
For diabetes, traditional approaches, such as whole pancreas transplantations come with many barriers including the high cost, the scarcity of donor organs and invasive nature of transplant procedures. There is a great need for more scalable and cost-effective solutions.
Diabetes affects 537 million people globally. While type 1 diabetes (T1D) and type 2
diabetes (T2D) differ in their etiology, they share an important common feature, a marked reduction in the number of functional, insulin-producing pancreatic beta cells.
For over 15 years, researchers at the Icahn School of Medicine at Mount Sinai in New York City have been at the forefront of diabetes research, striving to develop a drug capable of inducing the regeneration of human beta cells. In a significant breakthrough in 2015, they
discovered harmine, a small molecule that is capable of stimulating beta cell replication. These cells are crucial for regulating blood sugar levels. The team’s latest in vitro study involved harmine increasing and converting alpha cells to beta cells. This is a significant breakthrough as alpha cells are abundant in individuals with diabetes.
Esra Karakose, assistant professor in the Department of Medicine, is now
forging ahead with studies on the molecular pathways involved for this regeneration process.
Artificial intelligence (AI) is also playing a major role in advancing these developments. For diabetes management, a new clinical trial at the University of Virginia aims to assess an AI-powered insulin delivery system. This system is called the Bolus Priming System with Reinforcement Learning (BPS_RL). It automates
the dosing process based on glucose history and meal detection. This is particularly important for children and young adults. Current insulin delivery systems require user input to adjust insulin dosages, which leads to errors and risks.
Stem Cell Transplant Developments For Blood Cancers Set To Change 40 Years Of Standard Practice
This week, Australian researchers demonstrated that the use
of a new, less toxic drug combination after stem cell transplants for leukemia significantly improves patient outcomes post-transplant, reducing the risk of the life-threatening complication of Graft Versus Host Disease (GVHD).
The trial, led by Monash University and the Australasian Leukemia & Lymphoma Group (ALLG) will transform global blood stem cell transplant outcomes for people with high-risk blood
cancers.
“This new treatment triples the chances of a patient being alive, healthy and free of GVHD three years after stem cell transplant,” said lead researcher, Professor David Curtis, Director of Malignant Haematology Research at the Australian Centre for Blood Diseases, Monash University, and Clinical Haematologist and senior bone marrow transplant physician at The Alfred.
Blood stem cell
transplants are often lifesaving for leukemia patients, but they come with a high risk of life-threatening complications, especially in the first 100 days after transplant. Common side effects include infections, organ damage, and the often-debilitating Graft-versus-host disease (GVHD), an irreversible, lifelong complication.
“The trial showed the new treatment combination is simple, safe and more effective than current methods
in preventing GVHD, which contributes to death or life-long illness in 20% of patients undergoing a blood stem cell transplant,” Professor Curtis said.
“The trial has established a new benchmark for treatment in matched related donor transplantation.”
Results were published in the New England Journal of Medicine and presented at the European Hematology Association Meeting in Milan,
Italy.
These results are game-changing for stem cell transplant patients, with cyclosporin and cyclophosphamide offering a new standard of care for prevention of GVHD for patients with aggressive blood cancers undergoing transplant from a match-related blood stem cell donor.
The Medical Research Future Fund (MRFF) trial was a five-year, phase 3 randomized controlled trial that was
conducted across eight hospital sites in Australia and New Zealand. It tested a new drug combination in 134 patients aged 18–70, most of whom were living with acute myeloid leukemia (AML) or acute lymphoblastic leukemia (ALL).
Researchers compared the standard drug combination used for the last 40 years with a new combination of cyclophosphamide and cyclosporin. The new drug combination tripled the number of patients that were
alive, cured of blood cancer and not suffering from GVHD three years after transplant (49.1% vs 14.2% for the standard drug combination). Additionally, the risk of serious side effects was reduced to 19.7% from 32.4%.
Due to the success of the trial, the integration of this new treatment procedure is to be integrated immediately as the new standard of care in matched sibling transplants.
