Activity of Lorlatinib Based on ALK Resistance Mutations Detected on Blood in ALK Positive NSCLC Patients

2019-10-21 12:45:36 | BioPortfolio


This study includes patients diagnosed with a metatastatic non small cell lung cancer with ALK translacation. The standard treatment for patients with metastatic non small cell lung cancer with ALK translocation is represented by personalized treatment with drugs called ALK inhibitors. During the treatment with an ALK inhibitor, the tumour can start to grow again, because the tumour adapts to the drug and develops escape mechanisms, becoming resistant. At the tumour cells level, the mechanisms underlying resistance can include the development of other alterations, mainly mutations, including in the ALK gene. The alterations that developed depend on the drug the tumour has been exposed to.

The alterations can be identified by analysing tumour tissue obtained through a biopsy, however, repeating a tumour biopsy is difficult and risky and might not be able to provide sufficient tissue for the test. Therefore in the last years, new tests have been developed to identify the mutations in the blood.

Lorlatinib is a drug that inhibits ALK and has already been identified to be able to control the tumour growth when ALK mutations are identified and is already approved as standard treatment after progression to a previous treatment with ALK inhibitors.

The purpose of this study is to identify which patient populations may benefit most from treatment with lorlatinib, based on the alterations found in their genes.

Medical and Biotech [MESH] Definitions

Malignant neoplasm arising from the epithelium of the BRONCHI. It represents a large group of epithelial lung malignancies which can be divided into two clinical groups: SMALL CELL LUNG CANCER and NON-SMALL-CELL LUNG CARCINOMA.

A form of highly malignant lung cancer that is composed of small ovoid cells (SMALL CELL CARCINOMA).

A heterogeneous aggregate of at least three distinct histological types of lung cancer, including SQUAMOUS CELL CARCINOMA; ADENOCARCINOMA; and LARGE CELL CARCINOMA. They are dealt with collectively because of their shared treatment strategy.

A quinazoline derivative and ANTINEOPLASTIC AGENT that functions as a PROTEIN KINASE INHIBITOR for EGFR associated tyrosine kinase. It is used in the treatment of NON-SMALL CELL LUNG CANCER.

A cell adhesion molecule that contains extracellular immunoglobulin V and C2 domains. It mediates homophilic and heterophilic cell-cell adhesion independently of calcium, and acts as a tumor suppressor in NON-SMALL-CELL LUNG CANCER (NSCLC) cells. Its interaction with NATURAL KILLER CELLS is important for their cytotoxicity and its expression by MAST CELLS plays a role in their interaction with neurons; it may also function in synapse assembly, nerve growth and differentiation.
