Brief Title: Neoadjuvant Infigratinib, an Inhibitor of FGFR, in Upper Tract Urothelial Carcinoma

Tolerability and Activity of Neoadjuvant Infigratinib, an Inhibitor of FGFR, in Upper Tract Urothelial Carcinoma


  • Org Study ID: 2019-0557
  • Secondary ID: N/A
  • NCT ID: NCT04228042
  • Sponsor: M.D. Anderson Cancer Center


This phase Ib trial studies the side effects of infigratinib before surgery in treating patients with upper tract urothelial cancer. Infigratinib may stop the growth of tumor cells by blocking the activities of a gene called FGFR needed for cell growth. Giving infigratinib before surgery may cause the tumor to shrink, which may make the surgical procedure easier and/or reduce the need for more extensive surgery.



I. Evaluate the tolerability of infigratinib in patients with low-grade and high-grade platinum ineligible upper tract urothelial carcinoma (UTUC).


I. Assess tolerability in those with GFR 30-49. II. Evaluate the objective response rate (complete response [CR] + partial response [PR]) of infigratinib after 2 cycles in UTUC with and without FGFR3 alterations.

III. Correlate tumor tissue FGFR3 alteration (presence/absence, alteration type, and clonal status) with response and occurrence/severity of adverse events (AEs) such as hyperphosphatemia.

IV. Evaluate upper tract, bladder and local/distant recurrence within 12 months.

V. Evaluate renal function pre-treatment and after two treatments. VI. Evaluate patient-reported quality of life (QOL) outcomes during treatment.


I. Explore intra-tumor heterogeneity, gene expression profiles, and changes in tumor microenvironment using single cell ribonucleic acid (RNA) sequencing (scRNA-seq) and mass cytometry by time-of-flight (CyTOF) pre and post treatment to identify potential mechanisms of response and/or resistance, and correlation with the occurrence/severity of AEs.

II. Explore urinary/upper tract washing FGFR3 alterations as potential biomarker for detection and response.

III. Explore cell free deoxyribonucleic acid (cfDNA) for detection of FGFR3 alterations and as a predictor of response.


Patients receive infigratinib orally (PO) once daily (QD) on days 1-21. Treatment repeats every 28 days for up to 2 cycles in the absence of disease progression or unacceptable toxicity. During weeks 8-9 (at least 48 hours after last dose of infigratinib), patients undergo surgery.

After completion of study treatment, patients are followed up at 30 days, then every 3 months for up to 1 year after surgery.

Primary Outcome 1 - Timeframe: N/A


  • Renal Pelvis and Ureter Urothelial Carcinoma


Inclusion Criteria:
* Have low grade UTUC undergoing nephroureterectomy or ureterectomy, or high grade UTUC and not eligible for cis-platin neoadjuvant chemotherapy either due to medical comorbidities (e.g., cardiac dysfunction, hearing loss, glomerular filtration rate [GFR] < 50), or based on < 49% risk prediction of non-organ confined disease by clinical nomogram - * Have adequate biopsy tissue available for mutational analysis, as determined by the study pathologist, prior to enrollment. Any biopsy of index UTUC tissue available within 6 weeks of enrollment may be used - * Calculated or measured creatinine clearance >= 30 mL/min

- * Have an Eastern Cooperative Oncology Group (ECOG) performance status =< 2 - * Are able to read and/or understand the details of the study and provide written evidence of informed consent as approved by Institutional Review Board (IRB)/Independent Ethics Committee (IEC) - * Have recovered from AEs of previous systemic anti-cancer therapies to baseline or grade 1, except for alopecia - * Are able to swallow and retain oral medication - * Are willing and able to comply with scheduled visits, treatment plan and laboratory tests - * If a woman of childbearing potential (WOCBP), must have a negative pregnancy test within 7 days of the first dose of study drug. A woman is not of childbearing potential if she has undergone surgical sterilization (total hysterectomy, or bilateral tubal ligation or bilateral oophorectomy at least 6 weeks before taking study drug) or if she is post-menopausal and has had no menstrual bleeding of any kind including menstrual period, irregular bleeding, spotting, etc., for at least 12 months, with an appropriate clinical profile, and there is no other cause of amenorrhea (e.g., hormonal therapy, prior chemotherapy). WOCBP and males whose sexual partners are WOCBP must agree to use barrier contraception and a second form of highly effective contraception (Clinical Trials Facilitation Group, 2014) while receiving study drug and for 3 months following their last dose of study drug. Alternatively, total abstinence is also considered a highly effective contraception method when this is in line with the preferred and usual lifestyle of the subject. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception. Sexually active males must use a condom during intercourse while taking drug and for 3 months after the last dose of the study drug and should not father a child during this period. A condom is required to be used also by vasectomized men as well as during intercourse with a male partner to prevent delivery of the drug via seminal fluid
Exclusion Criteria:
* Have a history of another primary malignancy within 3 years except:
* Adequately treated in situ carcinoma of the cervix, non-melanoma carcinoma of the skin

- * Any other untreated cancer deemed by treating physician to be at low risk for progression during the study period (such as low or intermediate risk prostate cancer)

- * Curatively treated malignancy that is not expected to have recurrence or require treatment during the course of the study

- * Have uncontrolled bladder cancer. Patients with bladder cancer must have bladder cleared of disease by transurethral resection prior to initiating treatment and must not be at need for systemic therapy

- * Have any other medical condition that would, in the investigator's judgment, prevent the subject's participation in the clinical study due to safety concerns or compliance with clinical study procedures

- * Have current evidence of corneal or retinal disorder/keratopathy including, but not limited to, bullous/band keratopathy, corneal abrasion, inflammation/ulceration, keratoconjunctivitis, confirmed by ophthalmologic examination. Subjects with asymptomatic ophthalmologic conditions assessed by the investigator to pose minimal risk for study participation may be enrolled in the study
