MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Pancreatic cancer is a deadly disease and will soon be the second leading cause of cancer-related death.
We have made some progress in the last few years....but despite this, patients with advanced, inoperable pancreatic cancer (which represents about 80% of pancreatic cancer patients) still only live 12 months, on average. We desperately need new therapies, AND to think "outside the box" for the treatment of pancreatic cancer.
In that context, we have been learning that there are subgroups of patients with cancer whose tumors are particularly susceptible to certain therapies - either new therapies, or in some cases, approved therapies that would have not normally been used for that disease. These specific patient subgroups with "actionable" findings have been identified through extensive genetic and molecular characterization of a patient's tumor.
In the past there was a cynical perspective that pancreatic cancer did not harbor any "actionable" molecular abnormalities.
We have now demonstrated that:
1) There are clearly and undeniably patients with pancreatic cancer whose tumors do indeed harbor "actionable" findings. This represents at least 27% of pancreatic cancer patients, but may represent up to 50% as new therapies evolve. These percentages are also highly consistent with similar publications in the pancreatic cancer field over the last few years; and
2) Importantly, we have been following our patients longitudinally for outcomes, and while it is still early, there is a statistically significant improvement in progression-free survival when a patient with a specific actionable molecular abnormality is treated with the appropriately "targeted" therapy. This finding is also consistent with findings that have been observed in other cancer types.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: The best outcome of inflammatory breast cancer (IBC) is dependent on achieving a pathological completed response after neoadjuvant chemotherapy for primary inflammatory breast cancer, which is the most aggressive type of breast cancer.
We have conducted extensive preclinical work, which showed that EGFR is a potential therapeutic targets of IBC.
Based on this preclinical data, we have conducted a phase II study to determine the pathological complete response rate of panitumumab plus neoadjuvant chemotherapy for HER2 negative primary inflammatory breast cancer.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Organ transplant recipients (OTR) are at 100-fold higher risk to develop certain skin cancers compared to the general population due to immunosuppression, and thus preventing skin cancer in this population is critical.
Our study found that in a high-risk Australian OTR population, only half of patients practiced multiple measures of sun protection regularly.
However, after participating in a research study that required dermatology visits, patients were over 4-times more likely to report using multiple measures of sun protection regularly. Patients were more likely to have a positive behavioral change if they did not already undergo annual skin cancer screening prior to study participation.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: BOLERO-6 was conducted to fulfill postapproval regulatory commitments to the FDA and EMA to estimate treatment benefit with EVE + EXE vs EVE alone or CAP for ER+, HER2− ABC that had progressed on an NSAI. Everolimus plus exemestane has not previously been compared with everolimus alone or capecitabine in a randomized setting.Data describing everolimus alone are limited to a single phase 2 study of just 19 patients. Thus, the FDA deemed it important to ascertain the efficacy of everolimus alone for ER+ breast cancer, and to determine the contribution of exemestane to combination therapy with everolimus. Capecitabine is often the first chemotherapeutic agent given for ER+ breast cancer that has progressed on anti-estrogen therapy. It has a reported PFS of 4.1–7.9 months among patients with HER2-negative advanced breast cancer. However, it has a different safety profile to everolimus or exemestane, and a comparison of endocrine-based combination therapy with single-agent chemotherapy was yet to be conducted.
The median PFS with EVE + EXE (8.4 months) was consistent with BOLERO-2 (7.8 months), and compared to EVE alone here (6.8 months) corresponded to an estimated 26% reduction of risk of disease progression or death (HR 0.74).
A numerical median PFS difference was observed for CAP over EVE + EXE (9.6 vs 8.4 months), which may be attributed to various baseline characteristics favoring CAP and potential informative censoring. The median PFS with capacitabine was longer than expected based on previous trials. Interpretation of the results of BOLERO-6 must consider the limited sample size and open-label design.
