Osel’s LACTIN-V is a live biotherapeutic product addressing women’s health disorders. LACTIN-V is under IND for preventing BV and rUTI. It contains Lactobacillus crispatus CTV-05, a single strain of hydrogen peroxide-producing vaginal Lactobacillus that is part of the natural vaginal microbiome of many healthy women. It was selected for features that restore the vaginal microbiota, prevent urogenital infections and promote reproductive health. LACTIN-V targets clinical indications associated with dysbiosis of the vaginal microbiota where hydrogen peroxide-producing lactobacilli are depleted, such as bacterial vaginosis (BV) and recurrent urinary tract infections (rUTI). LACTIN-V is delivered vaginally with a proprietary applicator.
CBM588 is an orally-administered Clostridium butyricum strain with a long history of clinical use and safety in all age groups in Japan. In Japan, CBM588 has primarily been used to treat infectious and noninfectious diarrheal disorders associated with dysbiosis of the human gastrointestinal microbiome. CBM588 inhibits certain enteric pathogens and supports colonic homeostasis by producing butyric acid. The strain also possesses novel immunomodulatory activities. CBM588 is being developed in the U.S. under an IND for prevention of antibiotic associated diarrhea, including Clostridium difficile infection. It is currently being tested in two investigator-sponsored Phase 1 studies at the City of Hope Medical Center to improve clinical outcomes in hematopoietic stem cell transplant and advanced renal cell carcinoma.
MucoCept Technology Platform
Most viruses enter the body via mucosal surfaces. The natural microbiota at these sites, may neutralize some viral particles before infection of the host can occur. Using a proprietary technology, MucoCept harnesses the human microbiome and enhances it to further virus neutralization. In the current MucoCept platform technology, we have modified a commensal Lactobacillus to express a potent inhibitor of Human Immunodeficiency Virus type 1 (HIV-1). Proof of concept has been demonstrated in an animal model.
