Author Interviews, Breast Cancer, Brigham & Women's - Harvard, Chemotherapy, NEJM / 24.02.2019

MedicalResearch.com Interview with: Aditya Bardia, MBBS, MPH Director, Precision Medicine, Center for Breast Cancer, Attending Physician Massachusetts General Hospital Cancer Center Harvard Medical School Boston, MA 02114 MedicalResearch.com: What is the background for this study? Response: Metastatic triple negative breast cancer is associated with aggressive tumor biology, and tends to affect younger patients and African Amerians. The response rate with standard chemotherapy regimens in patients with pre-treated metastatic TNBC ranges from 10-15%, and median progression-free survival ranges from 3-4 months. The median survival of metastatic TNBC is around 12 months and has not changed in the past 20 years. Thus, treatment of metastatic triple negative breast cancer represents an unmet clinical need.   (more…)

MedicalResearch.com Interview with: Dr. Giuseppe Del Priore, MD, MPH Chief Medical Officer of Tyme Inc. MedicalResearch.com: What is the background for this study? What are the main findings? Response: Metastatic breast cancer, sometimes also called “stage IV” or “advanced breast cancer,” is the most extensive stage of breast cancer. It is an invasive cancer that has spread to other parts of the body, most often bones, lungs, liver, and brain. The current standard of care for metastatic breast cancer is systemic drug therapies, such as hormone therapy, chemotherapy, targeted drugs or a combination of these.  Because they reach every cell in the body, they have side effects that can worsen the patient’s quality of life. Existing treatments cannot cure metastatic breast cancer and are palliative in intent. This presents a great unmet need and challenge in treating patients with metastatic breast cancer. SM-88 is a novel relatively non-toxic combination therapy that harnesses cancer’s unique cell metabolism and oxidative stress to selectively drive cancer cell death. Earlier studies with SM-88 therapy demonstrated its potential efficacy in breast and other metastatic cancers. In this current report, we assessed the efficacy of SM-88 in patients with metastatic breast cancer from the first in human “Phase 1” and compassionate use programs from 2012 to 2017. Data demonstrated the potential efficacy of SM-88 in metastatic breast cancer with favorable safety and quality of life profiles. In addition, there were no indications of cross-resistance based on hormone profile, previous treatments or metastatic site. This is an extremely important finding since most cancer deaths are due to resistance to subsequent therapies.  As predicted by the SM-88 mechanism of action, we could not detect this problem with SM-88 use.

MedicalResearch.com Interview with: Judith A. Malmgren, PhD President, HealthStat Consulting, Inc Epidemiology Department University of Washington MedicalResearch.com: What is the background for this study? What are the main findings? Response: Metastatic breast cancer (MBC) has two types, de novo stage IV MBC discovered to be metastatic at initial diagnosis as advanced disease and recurrent MBC found on follow up after diagnosis and treatment for initial invasive breast cancer. Our institutional breast cancer registry tracks both de novo metastatic breast cancer and invasive breast cancer for distant metastases. With this information we were able to compare the presentation, treatment and outcomes of both types, something that is not possible in national SEER data as recurrent MBC is not tracked. We found a remarkable improvement in 5-year survival from 28% to 55% over time among the de novo metastatic breast cancer patients.  Recurrent MBC 5-year survival did not improve in the same time period (23% to 13%) although incidence of recurrent MBC fell from 18% to 7% from 1990 to 2010. Incidence of recurrent metastatic breast cancer hormone receptor and HER2 positive breast cancer declined the most, leaving a large number of triple-negative recurrent metastatic breast cancer cases in the most recent time period. Worse metastatic breast cancer survival was associated with recurrent vs. de novo MBC, hormone receptor negative disease, older age (70+) and visceral dominant disease. HER2 positive disease was associated with better outcomes. (more…)
