Research Focus - Pharmacology and Experimental Therapeutics
A successful drug development program requires a complete understanding of the pharmacology of the agents being evaluated.
Molecular Pharmacology Section
The Molecular Pharmacology Section (MPS) within the Medical Oncology Branch, CCR, NCI (the independent research section of Dr. Figg's) has, as its primary focus, understanding the pharmacology of new anticancer agents, using prostate cancer as the target disease and angiogenesis as the target pathway. The research within the MPS is focused on four major areas: development of anti-angiogenic agents, understanding the androgen regulatory pathway in prostate cancer, assessment of pharmacogenetic/pharmacodynamic biomarkers, and developing new treatments for castration-resistant prostate cancer (CRPC).
My laboratory has developed preclinical angiogenesis models (e.g., rat aorta, human saphenous vein) and high throughput screening assays to identify potential angiogenesis inhibitors and characterize their molecular pharmacology. We have a strong interest in developing targeted therapies against CRPC with a particular emphasis on the rational design and development of small molecule inhibitors of angiogenesis and of protein-protein interactions that have therapeutic potential for cancer therapy. The MPS has embarked upon an evaluation of several anticancer agents that appeared to inhibit tumor growth through novel mechanisms. Currently, in collaboration with several pharmaceutical/biotechnology companies, we are screening for compounds that inhibit angiogenesis. We are also designing new agents to hit key targets in this pathway. Using in vitro models optimized in our laboratory, we have identified several potential agents and are currently proceeding with preclinical testing that involve extensive dose-finding studies in the SCID model, mouse efficacy studies using PC3 and LNCaP prostate cancer xenografts as well as in mouse models of prostate cancer metastases. We have conducted phase I or phase II clinical trials of these agents in patients with prostate cancer.
For the past 15 years, we have been studying thalidomide and its analogs both in the laboratory and the clinic with encouraging results using rational therapeutic design. The antiangiogenic properties of thalidomide reported by D'Amato and colleagues prompted its clinical evaluation in various solid tumors, including prostate cancer. My laboratory subsequently determined that a metabolite of thalidomide was responsible for its antiangiogenic acitivity. The development of novel thalidomide analogs with better activity/toxicity profiles has been one of our ongoing research efforts, and in collaboration with several academic universities, we have synthesized over 187 thalidomide analogs and have screened them for activity as angiogenesis inhibitors. Based on the chemical structure of thalidomide, we synthesized several additional analogs including the N-substituted and tetrafluorinated thalidomide analogues as well as the glutarimide-derived metabolite of thalidomide, 5'-hydroxythalidomide. We have identified several extremely potent compounds in four different model systems and are moving those forward through clinical testing. We have also clinically evaluated thalidomide and lenalidomide as single agents and in treatment combinations with chemotherapy and other antiangiogenic agents in patients with CRPC.
We have integrated pharmacogenetics research in our drug development efforts by studying how germline genetic variants can alter pharmacokinetics, response, and toxicity of various anticancer agents, thereby contributing to inter-individual variation in clinical outcomes in therapies with an already narrow therapeutic window. We have established a molecular link between these polymorphisms and their phenotype as it relates to drug treatment. Our research has focused on genetic variations in drug metabolism and transporting candidate genes. We have characterized genetic polymorphisms that regulate androgens to better understand the associations between important androgen regulatory gene variants and prostate cancer progression.
Additionally, we have evaluated the impact of selected genetic polymorphisms in the androgen regulatory pathway on clinical outcomes in patients with prostate cancer. Several studies on the pharmacogenetics of membrane transporters, including adenosine triphosphate-binding cassette (ABC) transporters and organic anion transporting polypeptide (OATP) transporters, have linked transporter genotypes with clinical outcomes. Specifically, my laboratory has been studying OATP1B3, encoded by the SLCO1B3 gene, and its involvement in steroid hormone transport. We characterized its role in prostate cancer and the molecular mechanisms controlling its expression for future drug discovery efforts. We determined that the common SLCO1B3 334GG/699AA haplotype is associated with impaired testosterone transport and improved survival in patients with prostate cancer. Our findings further demonstrated that the specific polymorphism (334T>G) in SLCO1B3 increases testosterone import and is associated with a shorter time to androgen independence in patients with prostate cancer who are treated with androgen deprivation therapy (ADT). We are therefore interested in examining whether germline polymorphisms in other androgen regulatory pathways have the potential to be useful for prognosticating the response to ADT, designing clinical trials for patients who have poor germline prognostic features, and designing novel therapies targeted against genes that influence the response to ADT.
Clinical Pharmacology Program
The mission of the Clinical Pharmacology Program (CPP) within the Office of the Clinical Director, CCR, NCI, is to fully characterize the clinical pharmacology of new anticancer agents entering the CCR clinics. Today, the CPP is the only group available for clinical pharmacology collaboration. This program is divided into five cores: the Blood Processing Core, Bioanalytical Core, Preclinical Pharmacokinetics Core, Pharmacometrics Core and Pharmacogenetics Core. Dr. Figg has headed the CPP for the past 22 years.
The CPP is directly responsible for the pharmacokinetic (PK) analysis of numerous Phase I and II clinical trials conducted within the NCI. In addition, the CPP provides direct PK support for many studies performed elsewhere in the extramural community. The program provides bioanalytical support (LC-MS) and pharmacokinetic-pharmacodynamic (PK/PD) modeling and simulation of investigational agents or combination therapies to predict exposure-response in future trials (Pharmacometrics Core). The CPP can also assist with determining protein binding, drug-drug interactions, concentration-effect analysis, drug metabolism and routes of elimination for new anticancer agents.
The Blood Processing Core (BPC) can assist investigators within the NIH Clinical Center in the collection and processing of biological specimens (biological fluids). All samples will be processed according to the clinical protocol, bar-coded, and then entered into a database for sample handling and storage purposes. The BPC handles the shipment of samples to intramural or extramural laboratories.
The Preclinical Pharmacokinetics Core is open to collaboration for new anticancer agents that are being introduced into preclinical models and can develop bioanalytical assays to quantitate and characterize preclinical drug metabolism and pharmacokinetics in preclinical models.
The Pharmacogenetics Core is responsible for correlating outcome observations (side effects, efficacy, survival, and/or PK results) with genetic variance (mutations or somatic) to identify key genetic determinants and biomarkers that predict response to specific treatments.
