Ages Eligible for Study: | 18 Years to 99 Years (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Participant has provided informed consent/assent prior to initiation of any study specific activities/procedures
- Age ≥ 18 years old (or legal adult within country, whichever is older) at the time that the Informed Consent Form (ICF) is signed
- Pathologically confirmed squamous cell lung carcinoma
- Disease that is unresectable, locally advanced or metastatic (not amenable to curative therapy)
- Participants must have archived tumor tissue sample (formalin fixed, paraffin embedded [FFPE] sample [FFPE of excisional, or core needle]) taken within last 5 years or be willing to undergo pre-treatment tumor biopsy (excisional, or core needle) for tissue prior to enrollment
- Participant must have progressed on, or recurred after at least 1 prior systemic therapy (Part 1 and 2 only) or at least 2 prior systemic therapies (Part 3 only) for locally advanced and unresectable or metastatic disease. Prior treatment must include a platinum-based doublet chemotherapy and checkpoint inhibitor for advanced or metastatic disease, either given as one line of therapy or as individual lines of therapy, unless the participant has a medical contraindication to one of the required therapies (which must be documented in the electronic case report form [eCRF]). Additionally, if the participant's tumor was previously identified as having a driver mutation (according to local standard of care or guidelines, e.g., Kirsten rat sarcoma [KRAS] G12C, neurotrophic tyrosine receptor kinase [NTRK]), which has an approved therapy for which the participant is eligible and available, the participant must have received the approved therapy in a prior line of treatment.
- For Part 4, participants may not have received prior systemic therapy for their locally advanced and unresectable or metastatic disease. For Part 4, participants who received peri-operative systemic therapy are eligible if that adjuvant/neoadjuvant therapy was completed at least 12 months prior to diagnosis of locally advanced and unresectable or metastatic disease.
- Measurable disease per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1) criteria
- Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1

Exclusion Criteria:
- Mixed small-cell lung cancer or mixed non-small cell lung cancer (NSCLC) histology
- Untreated or symptomatic central nervous system (CNS) metastases or leptomeningeal disease
- Uncontrolled pleural effusion, pericardial effusion, or ascites requiring recurrent drainage procedures at a frequency greater than monthly
- Impaired cardiac function or clinically significant cardiac disease including: unstable angina within 6 months prior to first dose of study treatment, acute myocardial infarction < 6 months prior to first dose of study treatment, New York Heart Association (NYHA) class II-IV congestive heart failure, uncontrolled hypertension (defined as an average systolic blood pressure >160 mmHg or diastolic >100 mm Hg despite optimal treatment (measured following European Society for Hypertension/European Society of Cardiology [ESH/ESC] 2013 guidelines; Section 11.11), uncontrolled cardiac arrhythmias requiring anti-arrhythmic therapy other than beta blockers or digoxin, active coronary artery disease, Fridericia's correction formula (QTc) ≥ 470
- Evidence of any ongoing ophthalmologic abnormalities or symptoms that are acute (within 4 weeks) or actively progressing
- Recent (within 6 months) corneal surgery or ophthalmic laser treatment or recent (within 6 months) history of, or evidence of, corneal defects, corneal ulcerations, keratitis, or keratoconus, or other known abnormalities of the cornea that may pose an increased risk of developing a corneal ulcer
- Part 1 and Part 2: participants that experienced toxicity or hypersensitivity requiring discontinuation of prior docetaxel treatment
- Part 1 only: participants that had disease progression on prior therapy with docetaxel
- Part 2 only: participants have received prior docetaxel in unresectable or metastatic setting (including participants who received prior docetaxel in first line for metastatic disease, but not including participants who received prior docetaxel neoadjuvantly or adjuvantly and did not progress within 6 months of end of therapy)
- Prior treatment with any selective inhibitor of the fibroblast growth factor-fibroblast growth factor receptor (FGF-FGFR) pathway
