This is a Phase I/II clinical trial.
- A Phase I clinical trial tests the safety of an investigational intervention and also
tries to define the appropriate dose(s) of the investigational intervention to use for
further studies.
- Phase II clinical trials test the safety and effectiveness of an investigational
intervention to learn whether the intervention works in treating a specific disease.
- "Investigational" means that the intervention is being studied.
- In this research study, the investigators are investigating the combination of two
study drugs: alectinib and bevacizumab. The FDA (the U.S. Food and Drug
Administration) has not approved alectinib as a treatment for any disease.
It has been found that some people with NSCLC have a change (mutation) in a certain gene
called the anaplastic lymphoma receptor tyrosine kinase (ALK) gene. This mutated gene helps
cancer cells grow.
-- Alectinib belongs to a class of drugs designed to inhibit ALK. This drug has been used in
other research studies. Information from those other research studies suggests that alectinib
may be effective in killing cancer cells that have changes in ALK. Only participants with
changes in the ALK gene will be allowed to participate in this study.
In this research study, Alectinib will be combined with Bevacizumab.
-- Bevacizumab (also called Avastin) works by slowing or stopping the growth of cells in
cancer tumors by decreasing the blood supply of the tumors. If blood supply is decreased,
oxygen and nutrients that are needed for tumor growth are decreased. The FDA has approved
Bevacizumab as a treatment option for your disease
The purpose of this study is to test the safety of Alectinib and Bevacizumab. The
investigators will also determine how effective this combination is in participants with
advanced, ALK-positive NSCLC with a focus on participants with brain metastases.
