Kyoto University Hospital Starts First Human Trial of TRG-035 in 30 Men
3 articles · Updated · Boing Boing · May 29
Thirty adult men missing a tooth have entered the first human trial of TRG-035 at Kyoto University Hospital, a study designed to test safety rather than trigger tooth regrowth.
TRG-035 works by blocking a protein that keeps dormant tooth buds switched off; researchers say one antibody shot previously produced functional teeth in mice and ferrets without serious safety problems.
The first round began in late 2024 and followed participants for 11 months, with researchers saying actual tooth regrowth in these adults is unlikely.
If the drug clears this stage, the next trial will target children aged 2 to 7 born without teeth—a condition affecting about 1 in 1,000 people missing six or more teeth.
Toregem BioPharma aims to commercialize the treatment by 2030, potentially expanding later to people who lost teeth to decay or accidents.
A new drug can regrow teeth. Is this the beginning of the end for the dental implant industry?
If we can conquer tooth loss, how will this technology reshape our fundamental relationship with aging and natural decay?
By 'flipping a switch' to grow new teeth, what prevents this drug from causing unwanted growths elsewhere in the body?
TRG-035 Tooth Regeneration Drug Enters Human Trials: Safety Results and the Future of Dental Care
Overview
TRG-035, a groundbreaking tooth-regeneration drug, has entered its first human trials at Kyoto University Hospital. This innovative treatment is designed to stimulate the growth of new teeth by blocking a specific protein that acts as a natural off-switch for tooth development. By inhibiting this protein, TRG-035 aims to reactivate dormant tooth buds in adults who have lost teeth. The initial phase of the trial, which began in late 2024 and tracked participants for 11 months, focuses on evaluating the drug’s safety. This marks a major step forward in the quest to naturally restore lost teeth.
