Monoclonal Antibodies: Experienced in the development, production, purification, and PKPD characterization of monoclonal antibody drugs.
Ovarian Cancer Chemotherapy: A main objective of our research is to improve the safety and efficacy of ovarian cancer chemotherapy. Two main strategies are under investigation.
Develop mathematical models capable of characterizing the tremendous protocol-dependencies often observed in relationships between chemotherapeutic dosing and selectivity. Computer simulations are then utilized to predict optimal dosing strategies for the treatment of individuals.
Utilizes anti-drug antibodies to alter the distribution and elimination kinetics of chemotherapeutics as a means to provide targeted drug therapy of peritoneal metastases of ovarian cancer.
Our approach combines intraperitoneal administration of antineoplastic agents with systemic administration of anti-drug antibodies. The presence of anti-drug antibodies in the systemic circulation leads to rapid binding of drug diffusing out of the peritoneum and entering the blood, thereby reducing the extravascular distribution of the chemotherapeutic.
Pharmacokinetic and Pharmacodynamic: The utilization of pharmacokinetic and pharmacodynamic analyses and mathematical modeling to develop and evaluate rational approaches of optimizing drug therapy.
