Hummingbird: This study is evaluating the effectiveness of a new targeted therapy (called HMBD-001) in combination with chemotherapy, with or without additional targeted therapy, in people with advanced squamous non-small cell lung cancersA Phase 1b Study to Evaluate HMBD-001 in Combination With Docetaxel With or Without Cetuximab in Participants With Advanced Squamous Non-small Cell Lung Cancers
