OBESITY – INSULIN RESISTANCE – DIABETES PRECLINICAL CRO SERVICES
Our common goal with our clients is to tackle the worldwide obesity and type 2 diabetes epidemic. Physiogenex offers preclinical CRO services using innovative and benchmarked animal models of obesity, insulin resistance and type 2 diabetes. Along with these services, our clients take advantage of our great experience and consultancy expertise to optimize and accelerate their drug development programs.
Our clients benefit from our experts capabilities, which include classical in vivo test experiments (OGTT, ITT) and our innovative and gold standard radio-tracer based experiments: euglycemic – hyperglycemic – hyperinsulinemic clamp with 3H-glucose (for glucose turnover, hepatic glucose production, etc.) and 14C-2-deoxyglucose (glucose tissue uptake in muscle, adipose fat pads, etc.).
Our clients developing incretin-based therapies also benefit from our GLP-1 expertise.
Our integrative approach provides mechanistic understanding of your drug candidates’ efficacy for better translation to the clinical setting.
