- 4. Life expectancy > 12 weeks

- 5. Eastern Cooperative Oncology Group (ECOG) performance status:
* Part 1: 0 or 1

- * Part 2 and 3: 0, 1, or 2
Exclusion Criteria:
1. Treatment with other investigational study drug for any indication for any reason, or receipt of anticancer medications within 21 days or 5 half-lives before first dose of study drug

- 2. Prior receipt of a selective FGFR inhibitor

- 3. History of a calcium/phosphate homeostasis disorder

- 4. History and/or current evidence of ectopic mineralization/calcification

- 5. Current evidence of corneal disorder/keratopathy
