Benefits of technology

The patent text describes methods for treating a specific type of neuroendocrine tumor (NET) in individuals with the disease. These methods involve administering a therapeutic agent that targets a protein called tropomyosin receptor kinase (Trk). The NETs are associated with a fusion protein that contains Trk, which is a protein that has been found to be constitutively active in some cases. The methods may involve administering an agent that inhibits the activity of Trk, which is a protein that plays a role in cell signaling. The patent text also describes specific fusion proteins that can be targeted with the therapeutic agent. Overall, the patent text provides a technical solution for treating NETs that are driven by a specific fusion protein.

Problems solved by technology

With a median survival of only 33 months, patients with metastatic neuroendocrine tumors (NETs) have a poorer prognosis than previously realized.

Treatment of a NET with the Trk Inhibitor Entrectinib

[0070]A 28 year-old previously healthy male patient presented with progressive low back pain and 11 kg weight loss over the previous year. He was a never-smoker, occasional alcohol drinker, and an avid runner. The patient had no relevant family history of cancer. The patient's laboratory analysis revealed elevated levels of alkaline phosphatase (406 U / liter; normal range 38-126 U / liter), with serum chromogranin A (29 ng / ml; normal range <95 ng / ml), 24 hour urine 5-hydroxyindoleacetic acid (5-HIAA) (7 mg / day; normal range 0-15 mg / day), and serotonin (117 ng / ml; normal range 50-200 ng / ml) all found to be normal.

[0071]A right upper quadrant ultrasound noted echogenic masses present in the liver. A computed tomography (CT) scan identified low-density liver lesions, adrenal masses, bulky retroperitoneal and pelvic lymphadenopathy, and diffuse bony disease. Lumbar magnetic resonance imaging (MRI) revealed a diffusely abnormal marrow sig...

Identification of NTRK Fusion Genes in NETs using an Illumina® Next-Generation Sequencing (NGS) Platform

[0075]Tumor biopsies are taken from a patient having, or suspected of having, a NET. Formalin-fixed paraffin embedded (FFPE) tumor samples are prepared and tested using immunohistochemistry to identify patients potentially having an NTRK gene fusion or translocation. Patients with tumor samples indicating elevated levels of NTRK protein expression are then further tested by next-generation sequencing for confirmation and more detailed analysis of the NTRK genes.

[0076]The Archer® FusionPlex® NTRK Panel is a targeted sequencing assay that detects and identifies NTRK1, NTRK2, and NTRK3 fusions without prior knowledge of fusion partners or breakpoints. FusionPlex® panels utilize Anchored Multiplex PCR (AMP™) to generate target-enriched libraries for NGS. Designed for low nucleic acid input, AMP utilizes unidirectional gene-specific primers (GSPs) that enrich for both known and unknown...

Abstract

Disclosed herein, are methods of treating a neuroendocrine tumor (NET) in an individual in need thereof, comprising administering to the individual a therapeutically effective amount of an agent that inhibits a tropomyosin receptor kinase (Trk) protein, wherein the NET is associated with a Trk protein that has undergone a genetic translocation or is an NTRK gene fusion protein. Also disclosed herein are methods of treating a neuroendocrine tumor (NET) in an individual in need thereof, comprising: (a) obtaining a sample of NET genetic material from the individual; (b) determining whether the NET tumor comprises a NTRK translocation or gene fusion; and (c) administering to the individual a therapeutically effective amount of an agent that inhibits a tropomyosin receptor kinase (Trk) protein.

Description

CROSS-REFERENCE[0001]This application is a continuation of U.S. Application No. 15 / 683,630, filed on Aug. 22, 2017, which is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION[0002]With a median survival of only 33 months, patients with metastatic neuroendocrine tumors (NETs) have a poorer prognosis than previously realized. With a reported five-fold increase in incidence over the past thirty years and a prevalence of 35 per 100,000, the diagnosis and treatment of NETs have become an important unmet medical need.SUMMARY OF THE INVENTION[0003]Disclosed herein, in some embodiments, are methods of treating a neuroendocrine tumor (NET) in an individual in need thereof, comprising administering to the individual a therapeutically effective amount of an agent that inhibits a tropomyosin receptor kinase (Trk) protein, wherein the NET is associated with a Trk protein that has undergone a genetic translocation or is an NTRK gene fusion protein. In some embodiments, ...
