Brief summary: This phase II trial studies how well infigratinib works in treating solid tumors that have spread to other places in the body (advanced or metastatic) in patients with FGFR gene mutations such as FGFR1-3 gene fusions or other FGFR genetic alterations. Mutations are any changes in the genetic material (DNA) of a cell. FGFR proteins are involved in cell division, cell maturation, formation of new blood vessels, wound healing, and bone growth, development, and maintenance. FGFR mutations can cause the FGFR protein to become over-active in diseases such as cancer. Infigratinib may stop the growth of tumor cells by blocking FGFR proteins in these tumors.

Detailed description: PRIMARY OBJECTIVES:

I. To evaluate the efficacy of single agent infigratinib in patients with advanced or metastatic solid tumors of any histologic classification with FGFR1-3 gene fusions/translocations or other FGFR genetic alterations (with and without prior therapy with different FGFR inhibitor).

II. To understand response rate and potential for infigratinib to benefit patients who have FGFR alterations including point mutations, insertions/deletions and amplifications in different solid tumor types.

SECONDARY OBJECTIVES:

I. To further evaluate the efficacy of single agent infigratinib. II. To characterize the safety and tolerability of single agent infigratinib. II. To evaluate benefit of infigratinib in patients who have received one prior FGFR inhibitor.

EXPLORATORY OBJECTIVES:

I. To detect biomarkers of resistance to infigratinib treatment through tumor sequencing.

II. To develop a circulating tumor deoxyribonucleic acid (DNA) (ctDNA) or liquid biopsy assay optimized for monitoring response to infigratinib and detecting emerging resistance mutations to infigratinib.

OUTLINE:

Patients receive infigratinib orally (PO) once daily (QD) on days 1-21. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Patients who complete study treatment for any reason other than disease progression are followed for 30 days, every 8 weeks until disease progression, and then every 4 months for 1 year. All other patients are followed for 30 days, and then every 4 months for 1 year.

Eligibility criteria: Inclusion Criteria:

* Patients with histologically or cytologically confirmed advanced or metastatic solid tumors of any histologic classification at the time of diagnosis
* Written documentation of local or central Clinical Laboratory Improvement Act (CLIA)-certified laboratory determination of FGFR gene fusions/translocations or activating mutations
* The study is open to solid tumors in the following cohorts:

  * Cohort 1: Solid tumor patients with FGFR1-3 fusion/translocation (n=10) who have progressed on or are intolerant to standard of care (SOC) therapies and received treatment with a different FGFR inhibitor. Cholangiocarcinoma patients are permitted in this cohort
  * Cohort 2: Solid tumor patients with FGFR1-3 fusion/translocation (n, up to 30) who have progressed on or are intolerant to SOC therapies. Prior therapy with a different FGFR inhibitor is not permitted. Cholangiocarcinoma patients are excluded from this cohort (there are multiple competing studies and opportunities for patients to get treatment in other trials)
  * Cohort 3: Solid tumor patients with genetic alterations such as point mutations, insertions/deletions, or amplifications in any FGFR gene family member (n=10). Prior therapy with a different FGFR inhibitor is not permitted. Cholangiocarcinoma patients are permitted in this cohort
* Evidence of measurable or evaluable disease according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1
* Patients must have received at least one prior SOC regimen for advanced/metastatic cancer. Patient should have had evidence of progressive disease following their prior regimen, or if prior treatment was discontinued due to toxicity must have continued evidence of measurable or evaluable disease. Patients who have received prior treatment with an alternate FGFR inhibitor are still eligible for the study
* Patients with primary central nervous system (CNS) cancer or CNS metastases are excluded (because it is unclear how much CNS penetration the drug has). However, asymptomatic patients with history of successfully treated CNS metastases with surgery or radiation and follow up imaging showing stability, can be eligible

Women are considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least 6 weeks ago.
