Assessment of Clinical Response Following Atezolizumab and Bevacizumab Treatment in Patients With Neuroendocrine Tumors: A Nonrandomized Clinical Trial
Background Well differentiated NETs have been described as an "immunological desert" in recent years mainly due to the poor response rate data coming out of clinical trials of immunotherapy drugs. Poorly differentiated NEC has favoured better but mainly in the more obscure types. Which is why these data of a combo treatment containing one immunotherapy drug caught my eye. What is atezolizumab? It is a type of monoclonal antibody and a type of immune checkpoint inhibitor. It's a Programmed cell death protein -1 (PD-1)/ Ligand 1 (PD-L1) inhibitor. A drug that binds to the protein PD-L1 to help immune cells…
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…
Surufatinib for Neuroendocrine Cancer
UPDATE 2nd May 2022.US FDA did not approve. Commentary from Healthcare New company Global Data. "On 2 May, the US Food and Drug Administration (FDA) rejected HUTCHMED’s new drug application (NDA) for its lead candidate, Sulanda (surufatinib), for the treatment of advanced neuroendocrine tumours (NETs). Issues pertaining to trial populations were raised in a complete response letter (CRL) and GlobalData expects this case to have wide implications for the whole field of oncology therapeutics.China-based HUTCHMED received approval for its multi-receptor tyrosine kinase inhibitor Sulanda in China for the treatment of pancreatic and extra-pancreatic NETs in June last year and December 2020,…
Clinical Trials: Lenvatinib Efficacy in Advanced Neuroendocrine Tumours
Lenvatinib (LENVIMA) in Neuroendocrine Cancer — Updated January 2026 What is Lenvatinib? Lenvatinib is a targeted therapy known as a multikinase inhibitor. The brand name is LENVIMA. These drugs work by inhibiting multiple intracellular and cell‑surface kinases involved in tumour growth, angiogenesis, and metastatic progression. Targets include: VEGFR PDGFR FGFR c‑KIT Flt3 Because tumour progression typically involves multiple signalling pathways rather than a single driver, multikinase inhibition is a logical therapeutic strategy. How does it compare with other targeted therapies used in NETs? Sunitinib (Sutent) – a multikinase inhibitor targeting VEGF pathways; approved for pancreatic NETs. Everolimus (Afinitor) – an…
