Long-Term Safety and Efficacy of Teneligliptin in Elderly Patients with Type 2 Diabetes: Subgroup Analysis of a 3-Year Post-Marketing Surveillance in Japan

Introduction Teneligliptin, a dipeptidyl peptidase 4 inhibitor, was approved for the treatment of type 2 diabetes mellitus (T2DM) in Japan in 2012. However, clinical trials of teneligliptin involved limited numbers of elderly patients. Therefore, we investigated the safety and efficacy of teneligliptin in elderly patients with T2DM. Methods This 3-year follow-up RUBY surveillance registered patients with T2DM who started treatment with teneligliptin between May 2013 and February 2015 in Japan. Collected data included demographics, treatments, adverse drug reactions (ADRs), and laboratory variables. Data were analysed for patients in three age subgroups (
Plain Language Summary Teneligliptin is an oral drug taken once daily to manage blood glucose levels in people with type 2 diabetes. A number of studies of teneligliptin have investigated its safety and efficacy, but these studies included limited numbers of elderly people, aged 75 years or older. Following the approval of teneligliptin in Japan, post-marketing surveillance was started to monitor its safety and efficacy when prescribed by doctors to people in actual clinical practice. We analysed data from the surveillance to check if the safety and efficacy of teneligliptin differ in younger and older people separately. We found that there was no clear difference in the number of adverse drug reactions among three age subgroups
