An update on the first clinical trial evaluating a pluripotent stem cell-derived neural stem cell therapy for Huntington’s disease was presented today at the ISSCR 2026 Annual Meeting. The Phase 1b/2a REGEN4HD study represents a significant translational milestone following years of preclinical research, pivotal safety studies, regulatory engagement, and clinical trial development.

Huntington’s disease is a progressive neurodegenerative disorder with no currently available disease-modifying treatment. Regenerative medicine approaches using human stem cell-derived products are being investigated as a potential strategy to modulate disease pathology in the brain and address this substantial unmet medical need. The presentation at ISSCR 2026 highlights the launch of the first clinical trial of a pluripotent stem cell-derived therapy for Huntington's disease, marking an important step in translating regenerative medicine research toward potential new treatment approaches for this devastating neurodegenerative disorder.

A landmark study led from Lund, Sweden, has shown that transplanting stem-cell derived dopamine progenitor cells into the brain is feasible. Eight patients were transplanted in the first clinical trial, and no serious side effects linked to the transplanted cells were seen during the first year of follow‑up. The results are published in Nature Medicine.

A Team of Russian scientists have successfully developed a new series of oxazol-5(4H)-one derivatives  that function as potent and selective TrxR1 inhibitors. Led by Dr. Evgeny Chupakhin at Immanuel Kant Baltic Federal University in Kaliningrad the team used rational drug design to identify and synthesize the new compounds.

The research was led by corresponding author Dr. Amit Kumar of the Department of Public Health Dentistry, Santosh Dental College, Santosh Deemed to be University, Ghaziabad, Uttar Pradesh, India. Many dentists have never managed a haemophilia patient and lack the training to do so safely, leading to treatment delays, inconsistent practices, and — in the worst cases — uncontrolled bleeding after procedures that could easily have been managed with proper preparation. A new mini-review published in The Open Medicine Journal, authored by Dr. Sanjeev Kumar Singh and Dr. Abhilasha Smith (Department of Dentistry, SMMH Government Medical College, Saharanpur), Dr. Ajit Vishwakarma (Department of Dentistry, Government Medical College, Azamgarh), and Dr. Meena Jain (Department of Public Health Dentistry, Santosh Dental College, Ghaziabad), pulls together the current evidence and clinical guidance on this topic with the aim of equipping dental professionals with what they need to manage these patients confidently and safely.
