* FGFR gene fusion, mutation, or rearrangement as determined by standard CLIA-certified FDA-approved genomic panel (e.g. Ashion, Caris, FoundationOne etc.).
* Radiographically measurable or evaluable disease according to RECIST 1.1 criteria.
* Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2.
* Life expectancy ≥ 12 weeks.
* Females of child-bearing potential (defined as a sexually mature woman who (1) has not undergone hysterectomy \[the surgical removal of the uterus\] or bilateral oophorectomy \[the surgical removal of both ovaries\] or (2) has not been naturally postmenopausal for at least 24 consecutive months \[i.e., has had menses at any time during the preceding 24 consecutive months\]) must:

  1.

  2. Have a negative serum pregnancy test (β -hCG) result at screening and agree to ongoing pregnancy testing during the course of the study, and at the end of study participation. This applies even if the subject practices true abstinence\* from heterosexual contact.
* Male subjects must practice true abstinence\* or agree to use a condom during sexual contact with a pregnant female or a female of childbearing potential while participating in the study, during dose interruptions and for 1 week following discontinuation from study treatment, even if he has undergone a successful vasectomy.

Exclusion Criteria:

* Patients that have received prior treatment with a selective FGFR inhibitor
* History of and/or current evidence of ectopic mineralization/calcification, including but not limited to soft tissue, kidneys, intestine, myocardia, or lung, excepting calcified lymph nodes and asymptomatic arterial or cartilage/tendon calcifications.
* Current evidence of clinically significant corneal or retinal disorder confirmed by ophthalmologic examination.
* Use of any potent CYP3A4 inhibitors or inducers within 14 days or 5 half-lives, whichever is shorter, before the first dose of study drug. Topical ketoconazole will be allowed.
* Exposure to any therapeutic or investigational agent(s) within 3 weeks prior to initiation of study treatment.
* Major surgery within 4 weeks prior to initiation of study treatment.
* Any condition in the opinion of the principal investigator that might interfere with the patient's participation in the study or in the evaluation of the study results.
