Novartis Touts Positive Lutathera Phase 3 Data

Share

Novartis says the Phase 3 NETTER-2 trial met its primary endpoint of improvement in progression-free survival and the key secondary endpoint of objective response rate in patients with Grade 2 and 3 advanced gastroenteropancreatic neuroendocrine tumors (GEP-NETs) who received first-line treatment with Lutathera in combination with long-acting octreotide, versus high-dose octreotide alone. The company says the results will be discussed with FDA to determine whether it should seek the drug’s approval in newly diagnosed patients living with advanced GEP-NETs.

FDA approved Lutathera (lutetium Lu 177 dotatate) in 2018 for treating GEP-NETs that are positive for the hormone receptor somatostatin, including GEP-NETs in the foregut, midgut, and hindgut. The agency at the time said it was the first radiopharmaceutical approved for treating the tumors. The drug works by binding to a part of a cell called a somatostatin receptor, which may be present on certain tumors, according to the agency. After binding to the receptor, the drug enters the cell allowing radiation to cause damage to the tumor cells.
