A Study of Biomarker-Directed, Pembrolizumab (MK-3475) Based Combination Therapy for Advanced Non-Small Cell Lung Cancer (MK-3475-495/KEYNOTE-495)


Brief Summary

The purpose of this study is to test the safety and effectiveness of the study drug, pembrolizumab with specific drugs, to see how well these drugs work in combination and to see how the body handles these drugs in combination. This is a study to test a combination of investigational drugs for the treatment of non-small cell lung cancer (NSCLC). Both pembrolizumab and lenvatinib are approved for sale for the treatment of various types of cancers. MK-4280 is an investigational product and therefore has not been approved for sale. Using a combination of any of the study drugs is investigational.

Pembrolizumab, which is approved in the USA and some other countries, is available by prescription to treat several different cancers, but may not be approved to treat your type of cancer. Pembrolizumab works by helping your immune system to fight your cancer. Pembrolizumab is given IV through a vein.

MK-4280 is being developed by the Sponsor to treat cancer.

As of January 2018, MK-4280 has been given to about 84 adults with advanced cancer, both alone and in combination with pembrolizumab (MK-3475). The dose of MK-4280 was gradually increased in the study in order to find a dose that is safe and tolerable for people. For the 84 people dosed in the main portion of the study, 38 people have discontinued study treatment: 24 discontinued because their cancer continued to progress; 3 discontinued based on the decision of their doctor; 2 discontinued because they died due to disease progression, 7 discontinued because of a side effect related to study treatment; and 2 people chose to withdraw from the study. MK-4280 is given IV through a vein.

Lenvatinib is approved in the US, Europe and Japan for use in the treatment of progressive or advanced thyroid cancer in adults when radioactive iodine treatment has not helped to stop the disease. Lenvatinib is approved in the US and Europe for treating patients with advanced kidney cancer. Lenvatinib is also being tested for the treatment of other types of cancer and in this setting is considered to be an investigational drug. Lenvatinib has been given to approximately 2400 subjects in research studies. Lenvatinib belongs to a type of anti-cancer treatment known as receptor tyrosine kinase inhibitors (RTKIs). Tyrosine kinases are proteins involved in the growth of cells and the development of new blood vessels that supply them and can be present in high amounts in cancer cells. By blocking their action on cell receptors lenvatinib may slow the rate at which the cancer cells grow and help to cut off the blood supply that feeds the cancer. Lenvatinib is taken by mouth.

Patients will be followed for safety (exams, labs) monthly, and will have scans every 9 weeks.

About 3 people will take part in this study at UCLA. Up to 192 people are expected to participate in this study.
