Assessment of Clinical Response Following Atezolizumab and Bevacizumab Treatment in Patients With Neuroendocrine Tumors: A Nonrandomized Clinical Trial

Assessment of Clinical Response Following Atezolizumab and Bevacizumab Treatment in Patients With Neuroendocrine Tumors: A Nonrandomized Clinical Trial

Clinical Trials
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's a Programmed cell death protein -1 (PD-1)/ Ligand 1 (PD-L1) inhibitor i.e. it's a classic immunotherapy treatment.  A drug that binds to the protein PD-L1 to help immune cells kill cancer cells better and is used to treat many different types of cancer, including cancers that express PD-L1. Atezolizumab is used alone or with other drugs to treat certain types of melanoma, hepatocellular carcinoma (a type of…

Clinical Trial: Dostarlimab, anti–PD-1 monoclonal antibody in Neuroendocrine Carcinoma

Clinical Trials, Treatment
Whenever I post about a new trial or study, some people get excited without understanding that these new treatments and capabilities can very often take years to come to fruition and it's also possible that clinical trials can be halted, or that national approval agencies will not approve the final product.  Please bear that in mind when reading studies/clinical trials posted on RonnyAllan.NETBackgroundFollowing the Americal Society of Clinical Oncology (ASCO) conference in June 2022 (ASCO is the biggest Oncology event in the world), the media widely featured the results of the Phase 2 clinical trial of the drug Dostarlimab, an anti–PD-1 monoclonal antibody. The media often looks for headline-grabbing stories and this was one of them.  One UK TV outlet said they may have found the cure for cancer, which…

Immunotherapy: Studies with Neuroendocrine Neoplasms

Immunotherapy: Studies with Neuroendocrine Neoplasms

Clinical Trials, Treatment
IntroductionThere's a lot of Immunotherapy stuff out there! However, I also wanted to break it down and perhaps see if I can pick up the what, when, why, where and how in regard to Neuroendocrine Cancer. It's difficult, not least because the picture is not clear and there is no general roadmap printed, let alone one for Neuroendocrine disease. Immunotherapy for NETs was discussed at ENETS 2017 in Barcelona. The presentation that sticks out was one given by Dr Matthew Kulke, a well-known NET Specialist in Boston. My reaction to the presentation was one of 'expectation management' and caution i.e. it's too soon to know if we will get any success and when we will get it. He also hinted that it's more likely that any success will first be…
