The platelet derived growth factor receptor-α (PDGFRα) monoclonal antibody, olaratumab (IMS-3G3) by Eli Lilly, received Priority Review from the FDA on the strength of data from its Phase II trial in patients with soft tissue sarcoma (STS). The drug already received Orphan Drug, Breakthrough Therapy, and Fast Track designations from the agency. Continue reading
In the 1920’s Otto Warburg first discovered that tumor cells bypass normal cellular respiration i.e. glucose converted to pyruvate through glycolysis, and the sequential oxidation of pyruvate through the Krebs Cycle in the mitochondria. Instead tumor cells divert pyruvate to lactate dehydrogenase (LDH), which reduces pyruvate into lactate. This type of metabolism, referred to as The Warburg Effect, is normally observed in cells in hypoxic or anaerobic environments, in cells that are proliferating, or in cells in which the accumulation of pyruvate exceeds the capacity of the mitochondria.

A collaboration between Bristol-Myers Squibb and Kyowa Hakko Kirin to test a combination of Kyowa’s Poteligeo (mogamulizumab), an anti-CCR4 antibody, and BMS’ Opdivo (nivolumab) in a Phase I/II trial in advanced or metastatic solid tumors was announced. Also, Merck announced the acquisition of cCAM Biotherapeutics for $605MM for its CM-24 monoclonal antibody that target CEACAM1. Continue reading
Opdivo (nivolumab – BMS) and Cometriq (cabozantinib -Exelixis) demonstrated positive results in studies of patients with kidney cancer. Renal cell carcinoma is the most common type of kidney cancer in adults, accounting for more than 100,000 deaths annually. Globally, the five-year survival rate for those diagnosed with metastatic, or advanced kidney cancer, is 12.1 percent. Continue reading
The best way to cure cancer is to catch it early when surgical removal of a localized mass can successfully rid the patient of all cancer cells and cancer stem cells. This is no more important than in pancreatic cancer for which late stage therapies have not been shown to be very effective. (Thank you, Elaine, for sending me this article to discuss on the blog.)

Colony Stimulating Factor (CSF-1) is an essential growth factor for cells of the monocyte-macrophage lineage, including osteoclasts.
Cancers are tumors that cross the basement membrane and develop invasiveness, the ability to intravasate into blood vessels, and then to colonize and grow at distant sites. Complex heterotypic cellular interactions inside the tumor are responsible for this.
In a Phase 3 study of 929 patients with previously treated multiple myeloma, two proteasome inhibitors, Velcade (bortexomib – Johnson & Johnson and Takeda) ) and Kyprolis (carfilzomib – Amgen), in combination with dexamethasone, were compared. Patients treated with Kyprolis had a median progression-free survival of 18.7 months, versus 9.4 months for those treated with Velcade.
Angiopoietin inhibitor, trebananib, did not extend overall survival (OS) in a Phase 3 study in ovarian cancer. In the TRINOVA-1 trial of 900 women with recurrent ovarian cancer following platinum-based chemotherapy, patients receiving trebananib plus paclitaxel had a 19.3 month overall survival versus 18.3 months OS for women receiving paclitaxel, alone. The difference was not statistically significant. Continue reading
