"New therapies are urgently needed to prevent recurrent C. diff., a debilitating, costly and potentially life-threatening infection," said Dr. Sahil Khanna, Assistant Professor of Medicine, Department of Gastroenterology and Hepatology, Mayo Clinic, who is leading the study. "RBX7455 not only provides standardized and stabilized human microbes orally, but may provide several advantages in terms of patient dosing and therapy accessibility since no freezing or refrigeration is needed when the patient takes the product home."
The initiation of the Phase 1 study of RBX7455 enhances Rebiotix's clinical pipeline of human microbiome-directed drug candidates. The Company's lead drug candidate, RBX2660, recently completed a Phase 2b randomized, double-blind placebo-controlled trial examining the efficacy and safety of the microbiota restoration therapeutic as a prevention for recurrent C. diff. infection after a standard of care course of antibiotics (PUNCH™ CD2).
"Dosing the first patient in the Phase 1 study of RBX7455 is a significant milestone for Rebiotix as it solidifies our position as the most clinically advanced microbiome company in the industry, while showcasing the potential of our MRT platform to create new solutions for challenging diseases through standardized microbiota-based drug development," stated Lee Jones, president and CEO of Rebiotix. "RBX7455 is a potentially ground-breaking product for Rebiotix and the entire microbiome industry in that the lyophilized oral capsules do not need to be kept frozen and thus can be stocked in a pharmacy with no special handling or storage needs. As such, RBX7455 offers the unique opportunity to introduce live microbial therapy as a potential treatment for numerous diseases where chronic or repeat dosing is required."
About Clostridium difficile Infection
Clostridium difficile infection is a serious and potentially fatal disease, characterized by severe diarrhea, fever, and loss of appetite. It is a leading healthcare acquired infection. Some patients with C. diff. go on to experience more than one episode of the disease, which is known as recurrent C. diff. infection.2 Recurrent C. diff. infection is especially challenging to treat as the standard of care therapy may lead to recurrence.
