This study is for patients that have been diagnosed with non-small cell lung cancer. The purpose of this study is to treat patients with a drug called MK-3475 (pembrolizumab) with or without chemotherapy. Participants can expect to be on this study for up to 5 years.

This study is for patients that have been diagnosed with non-small cell lung cancer. The purpose of this study is to compare the usual treatment alone to using pembrolizumab plus the usual treatment. The investigational drug in this study is pembrolizumab. This drug, pembrolizumab is already approved by the FDA for use in patients with more advanced lung cancer. Participants can expect to be on treatment for up to a year. Participants will be followed for up to 10 years after completion of treatment.

This study is for patients that have been diagnosed with Metastatic EGFR-Mutant Lung Cancer. The purpose of this study is to compare the usual treatment of AZD9291 (osimertinib) alone to using bevacizumab plus AZD9291 (osimertinib). The drug, AZD9291 (osimertinib), is already approved by the FDA for use by itself to treat lung cancer. The drug, bevacizumab, is also already approved by the FDA when given with chemotherapy for treatment of advanced lung cancer. The addition of bevacizumab to other EGFR-targeting drugs has shown promise by delaying the time until progression on treatment for patients with EGFR-mutant lung cancers. Participants can expect to be on this study until their cancer returns or spreads, or the participant experiences unacceptable side effects, or until they decide to come off study. Participants will then be followed for 10 years after the date they enrolled to the study.

This study is for patients who have been diagnosed with solid tumor malignancy with KRAS G12C mutation. The investigational drug used in this study is MRTX849. The purpose of this study is to see if patients with cancer with a KRAS G12C mutation will benefit from treatment with MRTX849, what side effects occur and how often they occur and to see how quickly MRTX849 is absorbed into the blood stream and how fast it is removed by the body. Participants can expect to be in this study for as long as the disease does not get worse.

This study is for patients that have been diagnosed with non-squamous non-small cell lung cancer. The investigational drug used is MK-3475 (pembrolizumab). The purpose of this study is to compare any good and bad effects of using only the immunotherapy drug, MK-3475 (pembrolizumab), alone first versus the combination of the immunotherapy drug, MK-3475 (pembrolizumab), and chemotherapy. Participants can expect to be on this study for up to 2 years and followed for up to 5 years from when they began taking part in the study.
