Dr Holcombe's Research Interests
1. Colon cancer prevention: Colon cancer is the third leading cause of cancer death for both men and women in the United States. Preventing this disease through the development of novel agents, many of them derived from naturally occurring compounds, is an area of specific interest. These compounds are undergoing testing both in the laboratory and in pilot clinical trials.
2. Wnt Signaling in Cancer: The Wnt signal transduction pathway is critical for the development and progression of many cancers but colon cancer in particular. Laboratory research is ongoing which will define the role of specific components of the Wnt signaling pathway in colon cancer and define mechanisms by which activation of this pathway contributes to a malignant phenotype. These studies are performed with an eye toward the development of new diagnostic tests, validation of new prognostic markers, and implementation and testing of novel targeted therapeutic interventions.
3. Clinical and Translational Research: Dr. Holcombe’s major focus has been on the development of hypothesis-driven, investigator-initiated trials in the area of gastrointestinal malignancies. Currently, Dr. Holcombe has several clinical trials in development for the treatment of patients with colon cancer and other gastrointestinal malignancies.
4. Health Services and Healthcare Quality: Transitioning oncology care to value-based paradigms is essential and an area of research focus over the past several years. Dr. Holcombe has published numerous manuscripts related to healthcare quality and novel models of care delivery.
A FIRST-IN-HUMAN STUDY OF REPEAT DOSING WITH REGN2810, A MONOCLONAL, FULLY HUMAN ANTIBODY TO PROGRAMMED DEATH – 1 (PD-1), AS SINGLE THERAPY AND IN COMBINATION WITH OTHER ANTI-CANCER THERAPIES, IN PATIENTS WITH ADVANCED MALIGNANCIES
The purpose of this study is to find a safe dose level of REGN2810 alone and in combination with 1 or more of the following agents: radiotherapy, cyclophosphamide, GM-CSF, carboplatin and docetaxel. Other purposes of this study are to measure the levels of REGN2810 and pote...
A phase 2 randomized multicenter study of PEGPH20 (hyaluronidase) combined with nab-paclitaxel plus gemcitabine compared with nab-paclitaxel plus gemcitabine in subjects with stage IV previously untreated pancreatic cancer
This study is testing an experimental drug called PEGPH20. Experimental means the United States Food and Drug Administration has not approved PEGPH20 for ...
A feasibility and adherence study of personalized therapeutic interventions targeting minimal residual disease following adjuvant colon cancer therapy
This study involved the administration of one of several commonly used medications, low dose aspirin, atorvastatin (Lipitor) or Lisinopril (Zestril), or education about and assignment to a program of physical activity, in order to reduce the risk of relapse for patients with colo...
The purpose of this study is to determine if the addition of genistein, a natural product derived from soy will increase the chance of responding to chemo...
