This study is researching a new medicine called MORAb-202 for people with a type of lung cancer called metastatic non-small cell lung cancer adenocarcinoma (NSCLC AC). Metastatic means the cancer has spread to other parts of the body. The study will check if MORAb-202 is safe and how well it works. To be part of this study, you must have a specific type of lung cancer confirmed by tests. Also, your cancer should be measurable, meaning it can be seen and tracked by doctors. You need to be in good health, able to do daily activities, and not have other types of lung cancer or recent serious fluid build-up in your chest. You should not have had certain lung surgeries or recent chest radiation. The study involves regular visits to the clinic to monitor your health and the cancer's response to MORAb-202.

• The study involves regular clinic visits.
• Participants must have specific lung cancer type.
• Recent chest surgeries or radiation may disqualify you.
