Expert in Medicinal Chemistry/ Synthetic Organic Chemistry-Research and Patent Litigation
Expert ID: 736259 New Jersey, USA
1) Inventor of saxagliptin at BMS that was a breakthrough drug for type II diabetes as a sole therapy.
2) Inventor of lead molecule for bcl-2 inhibitor program venetoclax at Abbott Labs that caused the regression of solid tumors in preclinical oncology studies.
3) As Lexicon director of med chem, led team of 16 medicinal chemists in small molecule effort to IND and Phase IIb clinical trials for rheumatology, arthritis, and psoriasis.
4) Seven INDs (investigational new drugs) in oncology, immunology, metabolic and antiinfectives areas during career.
5) Eight years of consulting experience, beginning in Jan. 2012, writing expert reports following patent analysis covering obviousness, claims validation, enablement; depositions given. Expert was on a ANDA Hatch Waxman case as expert consultant; a case dedicated to claims validation and enablement that went on for two years, monthly reports; another ANDA case where obviousness was a crucial factor.
