BRIEF TITLE: Futibatinib (TAS 120) Plus Pembrolizumab in the Treatment of Advanced or Metastatic Urothelial Carcinoma

Brief Summary

The purpose of the trial is to evaluate a response to combination of Fibroblast Growth Factor Receptor (FGFR) inhibitor futibatinib and anti-programmed cell death-1 (PD-1) antibody pembrolizumab in patients with advanced or spreading urothelial cancer who are not candidates to receive a platinum-based treatment regimens. It also will help us to learn about the side effects of this combination therapy. This study will also help us to find the futibatinib and pembrolizumab predictive markers of response (i.e. benefit from specific treatment; helps to select particular treatment over another). Another objective is to evaluate the supposed futibatinib and pembrolizumab combination's immunomodulatory effects (i.e. Drug that modifies the immune response or the functioning of the immune system as by the stimulation of antibody formation or the inhibition of white blood cell activity). By conducting this study, we will learn about the variability in drug concentrations within a patient population receiving clinically relevant doses of a futibatinib and pembrolizumab. Pharmacokinetics allows us to examine how the body processes a drug.

Detailed Description

This study is an open-label, nonrandomized, multicenter Phase 2 study evaluating the
combination of futibatinib and pembrolizumab in patients with advanced or metastatic UC who
are not candidates to receive a platinum-based treatment regimen.

Approximately 46 subjects advanced or metastatic Urothelial Cancer (UC) will be enrolled in
the trial at approximately 15-17 sites worldwide:

- 6 patients in the safety lead-in

- 20 patients with tumors characterized by specific genetic abnormalities (Cohort A)

- 20 patients with tumors not characterized by specific genetic abnormalities (Cohort B).

A treatment cycle is defined as 21 days. All enrolled participants will receive the same

- Futibatinib at an oral (PO) dose of 20 mg daily (5 tablets) (QD); and

- Pembrolizumab at an intravenous (I.V.) dose of 200 mg every 3 weeks (Q3W).

Treatment will continue until disease progression, unacceptable side effects, or any other of
the criteria for treatment discontinuation is met; of note, pembrolizumab may be administered
for a maximum of 35 doses or a maximum duration of 2 years, whichever is earlier. The study
will begin with a safety lead-in period. During this period, a total of 6 patients with
advanced or metastatic urothelial carcinoma will be enrolled and treated for at least one
21-day cycle. Patients will be enrolled into this initial safety lead-in period without
regard for FGFR alteration status.

Primary Outcomes:

Primary Outcome 1 - Measure: To evaluate the objective response rate (ORR) of futibatinib in combination with pembrolizumab in patients with advanced or metastatic UC who are not candidates to receive a platinum-based treatment regimen

Primary Outcome 1 - Time Frame: Approximately 12 months


  • Advanced and Metastatic Urothelial Cancer


Inclusion Criteria:

1. Histologically confirmed advanced or metastatic urothelial carcinoma who have not
received systemic treatment for advanced metastatic disease. For patients who received
prior adjuvant/neoadjuvant chemotherapy or chemo-radiation for urothelial carcinoma, a
treatment-free interval >12 months between the last treatment administration and the
date of recurrence is required in order to be considered treatment-naïve in the
metastatic setting.

1. Cohort A: must have an FGFR3 mutation or FGFR1-4 fusion/rearrangement.

2. Cohort B: all other patients with UC (including patients with other FGFR or
non-FGFR genetic aberrations and patients with wild-type [non-mutated] tumors)

2. Unfit for or intolerant to standard platinum-based chemotherapy as defined by any one
of the following criteria:

a. Chronic kidney disease characterized by the estimated creatinine clearance rate
(eCCr) per Cockcroft-Gault formula of <60 mL/min or estimated glomerular filtration
rate (eGFR) of <60 mL/min/1.73 m2, corresponding to NCI-CTCAE v.5.0 Grade ≥2

b. Impaired hearing (measured by audiometry) of >25 decibel (dB) at two contiguous
test frequencies in at least one ear, corresponding to NCI-CTCAE v.5.0 Grade ≥2

c. Peripheral sensory neuropathy Grade ≥2 by NCI-CTCAE v.5.0

e. In the opinion of the Investigator, the patient is considered ineligible to receive
any platinum-based chemotherapy

3. Be willing and able to provide written informed consent for the trial.

4. Be ≥ 18 years of age.

5. Have an Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 to 1.

6. Adequate organ function as defined by the following criteria:

1. Absolute neutrophil count (ANC) ≥ 1.5 × 109/L

2. Platelet count ≥ 100,000/mm3

3. Hemoglobin ≥ 9.0 g/dL

4. Alanine transaminase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 × upper
limit of normal (ULN); if liver function abnormalities are due to underlying
liver metastasis, AST and ALT ≤ 5.0 × ULN.

5. Total bilirubin ≤ 1.5 × ULN, or ≤ 3.0 × ULN for patients with Gilbert's syndrome.

6. Creatinine clearance (Ccr) (calculated or measured value): ≥30 mL/min. For
calculated Ccr, use the Cockcroft-Gault formula.

7. International normalized ratio (INR) OR prothrombin time (PT) ≤1.5 × ULN unless
participant is receiving anticoagulant therapy as long as PT or Activated partial
thromboplastin time (aPTT) is within therapeutic range of intended use of

8. Phosphorus <1.5 ULN

7. Have a measurable disease per RECIST 1.1, as assessed by the local site
Investigator/radiology. Lesions situated in a previously irradiated area are
considered measurable if progression has been demonstrated in such lesions.

Exclusion Criteria:

1. Have received prior therapy with anti-PD-1, anti-PD-L1/L2 agent or FGFR inhibitor.

2. History and/or current evidence of any of the following disorders:

1. Non-tumor related alteration of the calcium-phosphorus homeostasis that is
considered clinically significant in the opinion of the Investigator
