Introduction
The drug lorlatinib (trade name EU: Lorviqua, U.S.: Lorbrena) has been approved in Germany since May 2019 for the treatment of advanced non-small-cell lung cancer. It can be used in adults who have already had treatment and who have certain mutated cancer cells that can lead to faster tumor growth.
Lung cancer is caused by the growth of malignant cells in the airways ( bronchi) and their branches (bronchioles). That is why this kind of cancer is also called bronchial carcinoma. There are two main types of lung cancer:
- Small-cell lung cancer (SCLC)
- Non-small-cell lung cancer (NSCLC)
NSCLC is surgically removed, if possible. But sometimes the tumor has already become too large or the cancer has spread to other parts of the body (metastasis) through the blood or lymphatic system. If this has happened, it is considered to be advanced lung cancer.
Some people with NSCLC have an abnormal enzyme in the tumor tissue called anaplastic lymphoma kinase (ALK). The full name of the cancer is then ALK-positive non-small-cell lung cancer. The enzyme ALK can lead to uncontrolled growth of the tumor tissue.
Lorlatinib is an ALK inhibitor. It is used to try to block the ALK enzyme and slow further tumor growth.
