Investigators are evaluating the combination of telotristat ethyl and Lutathera with a goal to improve progression-free survival in patients with well-differentiated neuroendocrine tumors in a randomized, phase 2 study that was highlighted during the 2020 NANETs Virtual Symposium.

Longer-term data demonstrated that treatment with the radiopharmaceutical Lutathera continued to show low rates of toxicity among patients with somatostatin receptor–positive neuroendocrine tumors.

Although chemotherapy remains the benchmark for drug development in pancreatic cancer, signals seen with selective KRAS-targeted agents, PARP inhibitors, and metabolic agents suggest that novel approaches do have the ability to prolong survival in the advanced setting.

Over the past decade in gastrointestinal cancer treatment, the acknowledgement that cancer is heterogeneous and likely polyclonal has prompted a shift from gene testing for some patients, to many patients.

The Japanese Ministry of Health, Labor, and Welfare has approved the antibody-drug conjugate trastuzumab deruxtecan for the treatment of patients with HER2-positive unresectable advanced or recurrent gastric cancer that has progressed following chemotherapy.
