Telotristat Ethyl: A Novel Therapy for Carcinoid Syndrome—Not a Panacea but a Step in the Right Direction
The multihumoral manifestations of neuroendocrine tumors include diarrhea, cutaneous flushing, wheezing, and right-sided valvular heart disease.1 Serotonin, a biogenic amine and product of tryptophan metabolism,2 mediates several of these symptoms.3,4 Diarrhea is a cardinal and often disabling...
Telotristat Ethyl Reduces Frequency of Bowel Movements in Patients With Metastatic Neuroendocrine Tumors and Carcinoid Syndrome

Personalized Dosimetry Optimizes Radiotherapy Dose in Patients With Neuroendocrine Tumors
Researchers at the 2016 Annual Meeting of the Society of Nuclear Medicine and Molecular Imaging (SNMMI) presented a molecular imaging methodology that allows the increase of the radiotherapy dose to the tumor while protecting vulnerable vital organs.1 The delicate balance of administering the...
FDA Approves New Diagnostic Imaging Agent to Detect Rare Neuroendocrine Tumors
The U.S. Food and Drug Administration (FDA) has approved Netspot, the first kit for the preparation of Ga-68 dotatate injection, a radioactive diagnostic agent for positron-emission tomography (PET) imaging. This radioactive probe will help locate tumors in adult and pediatric patients with...

Heinz-Josef Lenz, MD, of the University of Southern California, and Jonathan R. Strosberg, MD, of the H. Lee Moffitt Cancer Center and Research Institute, discuss efficacy and safety results in patients with midgut neuroendocrine tumors treated with lutetium Lu-177 dotatate (Abstract 4005).
Everolimus Improves Progression-Free Survival in Advanced Neuroendocrine Tumors of the Lung or Gastrointestinal Tract
In a phase III trial (RADIANT-4) reported in The Lancet, James C. Yao, MD, of the University of Texas MD Anderson Cancer Center, and colleagues found that everolimus (Afinitor) and supportive care significantly prolonged progression-free survival vs placebo and supportive care in patients with...
Everolimus Effective in Neuroendocrine Tumors of Gastrointestinal Origin
In a subgroup analysis of the phase III RADIANT-4 trial, focusing on neuroendocrine tumors of gastrointestinal origin, the mTOR inhibitor everolimus (Afinitor) essentially doubled the median progression-free survival time, compared with placebo, researchers reported at the 2016 Gastrointestinal...
Extended-Release Lanreotide Significantly Delays Disease Progression in Patients With Neuroendocrine Tumors in Large Phase III CLARINET Trial
A strong antiproliferative response was shown for the somatostatin analog lanreotide (subcutaneous, extended-release formulation, Somatuline Autogel [Somatuline Depot in the United States]) in patients with gastroenteropancreatic neuroendocrine tumors, in the large multinational prospective phase...
Radiopharmaceutical Receives Orphan Drug Designation
The radiopharmaceutical gallium-68 dotatate has been given orphan drug designation by the U.S. Food and Drug Administration and the European Medicines Agency for use as a diagnostic agent for the management of gastroenteropancreatic neuroendocrine tumors (GEP-NETs). Gallium-68 dotatate is owned by...
For Progressive Neuroendocrine Tumors, Clinical Benefit Is High With Capecitabine Plus Temozolomide
In an interim analysis of a phase II trial, 97% of patients with progressive metastatic neuroendocrine tumors achieved clinical benefit with the combination of capecitabine and temozolomide (CAPTEM). The results were reported at the 2014 Gastrointestinal Cancers Symposium by Robert L. Fine, MD,...
FDA Grants Priority Review to Lanreotide Injection for Gastroenteropancreatic Neuroendocrine Tumors
The U.S. Food and Drug Administration (FDA) has accepted and granted priority review to Ipsen’s supplemental New Drug Application (sNDA) for the somatostatin analog lanreotide (Somatuline Depot) 120 mg injection in the treatment of gastroenteropancreatic neuroendocrine tumors. The FDA designates...
Clinically Relevant Survival Benefit Seen for Everolimus in Pancreatic Neuroendocrine Tumors
Final results from the RADIANT-3 trial showed a 6-month difference in overall survival favoring everolimus (Afinitor) plus best supportive care over placebo plus best supportive care in patients with well-differentiated advanced and progressive pancreatic neuroendocrine tumors.1 Although the...
Lanreotide in Gastroenteropancreatic Neuroendocrine Tumors
In the Clinic provides overviews of novel oncology agents, addressing indications, mechanisms, administration recommendations, safety profiles, and other essential information needed for the appropriate clinical use of these drugs. On December 16, 2014, lanreotide (Somatuline depot injection) was ...
Lanreotide Evaluated in Pancreatic Neuroendocrine Subgroup
The somatostatin analog lanreotide (Somatuline) depot extended the time to disease progression in patients with pancreatic neuroendocrine tumors, in a planned subgroup analysis of the CLARINET trial, Alexandria T. Phan, MD, of The Houston Methodist Hospital in Texas, reported at the 2015...
Treatment Options Expanding for Neuroendocrine Tumors
Patients with advanced neuroendocrine tumors have two promising new treatment options, according to studies that earned spots in the Presidential Session of the 2015 European Cancer Congress, held recently in Vienna, Austria. The phase III studies evaluated the mTOR inhibitor everolimus (Afinitor)...
Telotristat Etiprate Added to Standard Therapy for Carcinoid Syndrome Shows Clinical Benefit in Patients With Metastatic Neuroendocrine Tumors
The investigational drug telotristat etiprate was shown to have clinical benefit when added to somatostatin analog therapy for carcinoid syndrome not adequately controlled by long-acting somatostatin analog therapy, the current standard of care, in patients with metastatic neuroendocrine tumors....
