Targeted Therapy for Neuroendocrine Cancer – Sunitinib (Sutent)

Click here to see the A to Z of Neuroendocrine Cancer What is Sunitinib (Sutent)? Manufactured by Pfizer, this is a targeted biological therapy or more accurately, a multitargeted tyrosine kinase inhibitor (TKI). You may also see it described as an anti-angiogenic agent on the basis that these tumor types are highly vascularized and show high expression of something called vascular endothelial growth factor (VEGF), a key driver of angiogenesis in neuroendocrine tumors. Because NETs are generally hypervascularized tumors, treatment with antiangiogenic drugs seems a rational approach. A complex process but in the simplest of terms, sunitinib blocks a particular enzyme and keeps tumors from making their own blood vessels, which are needed to deliver oxygen and other nutrients to help them survive and grow. In clinical trials, SUTENT was…

Clinical Trials – Surufatinib for Neuroendocrine Cancer

Clinical Trials, Treatment

What is Surufatinib?Surufatinib is a novel, oral angio-immuno kinase inhibitor that selectively inhibits the tyrosine kinase activity associated with vascular endothelial growth factor receptors (VEGFR) and fibroblast growth factor receptor (FGFR), which both inhibit angiogenesis, and colony stimulating factor-1 receptor (CSF-1R), which regulates tumor-associated macrophages, promoting the body’s immune response against tumor cells. Its unique dual mechanism of action may be very suitable for possible combinations with other immunotherapies, where there may be synergistic anti-tumor effects. Update 17th November 2021. Interim findings from a phase 1 dose-escalation and dose-expansion study, which were presented during the 2021 NANETS Symposium, demonstrated antitumor activity with surufatinib in heavily pretreated, United States-based patients with progressive NETs. Moreover, the data were consistent with 2 completed phase 3 studies that were performed with surufatinib in Chinese…

Neuroendocrine Tumor Drug Clinical Trial – Cabozantinib (includes news on Pheochromoctyoma and Paraganglioma)

Clinical Trials

What is Cabozantinib?Cabozantinib is an oral drug which works by blocking the growth of new blood vessels that feed a tumour. In addition to blocking the formation of new blood cells in tumours, Cabozantinib also blocks pathways that may be responsible for allowing cancers cells to become resistant to other "anti-angiogenic" drugs. It is a type of drug called a growth blocker. Cabozantinib has been studied or is already in research studies as a possible treatment for various types of cancer, including prostate cancer, ovarian cancer, brain cancer, thyroid cancer, lung cancer, and kidney cancer. During my research, I found that it has a connection to Medullary Thyroid Cancer (MTC) which is a type of Neuroendocrine Cancer, frequently associated with Multiple Endocrine Neoplasia (MEN). Cabozantinib, under the brand name of 'Cometriq'…
