· Senior Scientist/Research Scientist, Basic Pharmaceutics Section 1976 – 1979
· Member of multiple Lead Compound Project Development Teams and Task Forces
· Managed Section consisting of 2 Senior (Ph.D.) level supervisors and junior (2 B.S.) level Chemists in the Preformulation / Physical Pharmacy Group; and one senior (Ph.D.) level supervisor and 4 junior (B.S.) level Chemists in the Dissolution Group.
· The Dissolution Group was heavily dependent upon the use of in house developed robotics. They supported Formulation, Packaging and Clinical Supplies Development with Initial and Stability determinations.
· Managed the integration of the Physical-Pharmacy/ and Dissolution Groups from the Pharmaceutical Development Dept into the Analytical Development Dept.
· Physical-Pharmacy
· Providing relevant experimental studies to create data characterizing NCEs and APIs in support of Research and Development with primary responsibility to support formulation development and remediation of problematic properties of NCEs,
· Evaluation and feasibility of novel drug delivery systems and analytical methods,
· Providing Numbered Departmental Reports and documents for IND/NDA regulatory submissions
· Method Development
o Developed, validated and published model methods for
· Evaluation and selection of final salt and polymorphic forms of lead NCEs for formulation, clinical and commercial development.
· Studying corrosivity and filming of APIs, API-excipient compatibilities.
§ Determination of the vapor pressures of API solids.
§ Conducting API-Drug Excipient Compatibilities simulating wet granulation
· Discovery: Medicinal Chemistry and Pharmacology Support
o Determined and published reliable experimental pKa and log P values for intramural structure SAR by CVS, CNS, Endocrine and NSAID Medicinal-Chemistry and Pharmacology Discovery Teams that led to the discovery and selection of lead NCEs.
· Clinical and Pre-Clinical (Drug Safety and Pharmacokinetics/Drug Metabolism) Support
o Determined NCE solubilities to support/create novel preclinical and clinical delivery systems for animal safety, animal and human Bioavailability (BA), Metabolism and Pharmacokinetic studies. Delivery systems included drug laden oil/water iv emulsion, in situ solubilization, and softgel delivery systems for practically insoluble NCEs.
· Chemical Development Support
o Initiated in house practice utilizing X-ray Powder Diffraction (XRD) for qualitative/quantitative polymorphic analyses of every new batch of each NCE in development from project initiation to commercialization, to identify, study, and control polymorphic form (pedigree) and quantity
· Line Extensions
o Developing less soluble salt forms of haloperidol for i.m. administration and linogliride oral extended release; highly (5000 x more) soluble salts of zomepirac for i.m administration; and log P – SAR models for selection of an optimal form of an API for transdermal delivery.
· Dissolution Laboratory
· Developed dissolution methods for immediate (IR), controlled (CR), sustained (SR), extended (ER) dosage forms and topical drug delivery systems (TDDS).
· Provided Dissolution data for all formulations of NCEs, competitor’s products and reference compounds and reformulated/encapsulated reference products for Formulation Development and Clinical Development.
· Provided data for Dissolution Stability Program for dosage forms and packaging stability studies.
cGMP Compliance, SOPs Numbered Regulatory Reports, CMC Submissions
· Maintained cGMP compliant laboratories by developing and training staff, establishing SOPs for preformulation activities; developing expertise within staff, rational development and validation of dissolution methods; evaluation and incorporation of new methodologies, and delegating to responsible staff members.
· Wrote / Reviewed Numbered Reports and Pharm. Dev. CMC Sections for IND and NDA submissions for 5 NCEs and 6 API supplier or commercial synthesis procedure changes. Set/reviewed/authorized changes to specifications for particle size and dissolution, polymorphic form and responded to regulatory questions.
