resTORbio Completes Dosing of Patients in Phase 2b Study to Reduce the Incidence of Respiratory Tract Infections in the Elderly
“RTIs are a leading cause of hospitalizations and death among the elderly and are mainly caused by viruses that lack effective treatments,” said
The randomized, double-blind placebo-controlled Phase 2b trial was initiated to evaluate the safety, tolerability and efficacy of RTB101 alone or in combination with everolimus in reducing the incidence of RTIs. The study enrolled 652 subjects at increased risk of RTI-associated morbidity and mortality, defined as aged 85 and over or 65-84 with comorbidities. The study consists of two parts during which elderly subjects were enrolled during the winter cold and flu seasons in the southern (Part 1) and northern (Part 2) hemispheres. Part 2 of the study commenced in the U.S. in the fourth quarter of 2017 following an interim analysis of Part 1 results. Part 2 is a 4-arm study comparing placebo to 10 mg of RTB101 dosed once daily (QD), 10 mg of RTB101 dosed twice daily (BID), or 10 mg of RTB101 and 0.1 mg of everolimus dosed QD. All subjects were treated with study drug for 16 weeks, followed by eight weeks of follow-up.
resTORbio, Inc. is a clinical-stage biopharmaceutical company focused on helping people live healthier longer through the development and commercialization of novel therapeutics for the treatment of aging-related diseases. resTORbio’s lead program is targeting the selective inhibition of TORC1 - an evolutionary conserved pathway that contributes to the decline in function of multiple organ systems, including the immune, cardiac and neurologic systems. RTB101, resTORbio’s lead drug candidate, is a selective, orally administered, TORC1 inhibitor currently being investigated in a Phase 2b clinical trial as a first in-class immunotherapy for reducing the incidence of respiratory tract infections in the elderly by enhancing the function of the immune system. The company expects to develop RTB101 for additional aging-related indications such as heart failure or neurodegenerative diseases.
