Phase 3 CABINET Clinical Trial – Cabozantinib for Advanced Neuroendocrine Tumours

BREAKING NEWS - 24TH AUG 2023 Exelixis Announces Remarkable Efficacy in CABINET Trial for Advanced Neuroendocrine Tumors On August 24, 2023, Exelixis made an exciting announcement regarding the Phase 3 CABINET pivotal trial. This trial focused on evaluating the effectiveness of cabozantinib in treating advanced pancreatic and extra-pancreatic neuroendocrine tumors. The CABINET trial was a significant undertaking, involving multiple centers and enrolling a total of 290 patients who were divided into two groups. The trial progressed smoothly, but to everyone’s surprise, it was stopped early. The reason for this premature conclusion was the remarkable improvement in efficacy observed. The Alliance for Clinical Trials in Oncology independent Data and Safety Monitoring Board unanimously recommended ending the trial due to these unprecedented results. "CABINET trial will be unblinded and stopped early due…

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

Clinical Trials and Research

BackgroundWell 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 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…

Targeted Therapy for Neuroendocrine Cancer – Sunitinib (Sutent)

Clinical Trials and Research, Treatment

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…

Surufatinib for Neuroendocrine Cancer

Clinical Trials and Research, Treatment

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, respectively. Following the submission to Chinese authorities, NDAs were also submitted to the FDA and European Medicines Agency (EMA). Two large Phase III studies formed the basis…

Clinical Trial: Lenvatinib Efficacy in Metastatic Neuroendocrine Tumors (TALENT)

Clinical Trials and Research

"Interestingly, the ORR in pancreatic NETs was 44%, a rate not seen before with targeted agents," Jonathan Strosberg, MD, head of the neuroendocrine tumor division at Moffitt Cancer Center in Tampa Tweet Lenvatinib has completed a Phase 2 trial in Gastrointestinal (GI) and Pancreatic Neuroendocrine Tumours. The trial was sponsored by Grupo Espanol de Tumores Neuroendocrinos (Spanish NET scientific organisation) and the manufacturers. A European venture with sites in Austria, Italy, Spain, UK. Headline: The responses are better than Everolimus (Afinitor) and Sunitinib (Sutent).What is Lenvatinib?It is a type of targeted therapy known as a multikinase inhibitor. The brand name is 'LENVIMA'. These work by inhibiting multiple intracellular and cell surface kinases, some of which are implicated in tumour growth and metastatic progression of cancer, thus decreasing tumour growth…
