With its wholly owned subsidiary, Marvel Biotechnology Inc, announces it has initiated its 10-day, dose-ranging toxicology study, using dogs, for its lead drug candidate MB-204. To date, the Company's MB-204 has shown positive and promising data addressing depression, anxiety as well as its potential benefit in protecting patient's vital organs while going through chemotherapy treatments. As the maximum tolerated single-dose studies have been completed, FDA guidelines for drug development next prescribe an approximately one-week multiple dosing study required to run the industry standard 4-week good lab practise (GLP) toxicology studies. The studies are all required by the FDA prior to entering FDA Phase I human trials. Marvel Biosciences Corp shares V.MRVL are trading unchanged at $0.14.
