Biomarker-directed Neoadjuvant Therapy for Cisplatin-ineligible or Cisplatin-refusing Muscle-invasive Bladder Cancer: Phase I Bladder Cancer Signal Seeking Trial

INTRODUCTION

  • Org Study ID: 21-162
  • Secondary ID: N/A
  • NTC ID: NCT04972253
  • Sponsor: Guru P. Sonpavde

DESCRIPTION

Cisplatin-based chemotherapy is considered the gold standard treatment prior to surgery in patients with invasive bladder cancer. In this trial, we are testing whether using an oral pill targeting a mutated receptor in bladder and urothelial cancers is safe and effective when given for 2 months before surgery in patients who have invasive bladder or urothelial cancer and are planned for surgery but cannot receive cisplatin-based chemotherapy.

BRIEF SUMMARY

The aim of this research is to see whether using a drug that blocks a protein called FGFR (fibroblast growth factor receptor) prior to surgery is safe and effective in patients with bladder cancer that have mutations in FGFR3 or FGFR2 and who cannot receive chemotherapy with cisplatin prior to surgery

The name of the study drug involved in this study is:

- Infigratinib

DETAILED DESCRIPTION

This is a single-center (DF/HCC) prospective feasibility study to assess biomarker-directed neoadjuvant therapy in patients with cT2-T4aN0 MIBC who are candidates for radical cystectomy (RC) and ineligible for, or refuse, cisplatin-based neoadjuvant chemotherapy (NAC).

This research study involves using a drug that inhibits FGFR in patients with bladder cancer (that have mutations in FGFR) prior to surgery.

The name of the study drug involved in this study is:

- Infigratinib

The research study procedures include pre-screening for eligibility and study treatment including evaluations and follow up visits. This pre-screening is already done as clinical care. Study participants will receive study treatment for 2 months prior to surgery and will be followed for at least 1 year after undergoing surgery.

It is expected that about 12 people will take part in this research study.

This research study is a Phase I clinical trial, which tests the safety of an investigational drug (infigratinib) and also tries to define the appropriate dose of the investigational drug to use for further studies. "Investigational" means that the drug is being studied.

This research study is also a Feasibility Study, which is the first time investigators are examining this drug in patients with bladder cancer that has not spread to other organs. The U.S. Food and Drug Administration (FDA) has not approved infigratinib as a treatment for any disease.

Ineligibility for cisplatin-based chemotherapy, defined by any of the following:
Creatinine clearance (CL) <60 mL/min. GFR should be calculated from serum/plasma creatinine using the Cockcroft-Gault formula. - CTCAE v5.0 Grade > 1 hearing loss

- CTCAE v5.0 Grade > 1 neuropathy

- NYHA Class > II cardiac dysfunction

- Patients not meeting the above criteria are eligible if he/she declines neoadjuvant cisplatin-based chemotherapy after specific informed consent describing the known benefits of cisplatin-based chemotherapy. The reason for cisplatin-ineligibility based on the above criteria or cisplatin refusal should be documented on the case report form.
Adequate organ function laboratory values as defined below:
Hemoglobin ≥ 9.0 g/dL

- Absolute neutrophil count (ANC) 1.5 x (> 1500 per mm3)

- Platelet count ≥100 x 109/L (>75,000 per mm3)

- International Normalized Ratio (INR) or activated partial thromboplastin time (aPTT) < 1.5 x ULN, unless the patient is receiving anticoagulation therapy provided INR or PTT is within the therapeutic range of the intended anticoagulant therapy.
Serum bilirubin ≤1.5 x institutional upper limit of normal (ULN)
-- This will not apply to patients with confirmed Gilbert's syndrome (persistent or recurrent hyperbilirubinemia that is predominantly unconjugated in the absence of hemolysis or hepatic pathology), who will be allowed only in consultation with their physician.
AST (SGOT)/ALT (SGPT) ≤1.5 x institutional upper limit of normal
Measured creatinine CL >30 mL/min or Calculated creatinine CL>30 mL/min by the Cockcroft-Gault formula or by 24-hour urine collection for determination of creatinine clearance:
Males: Creatinine CL (mL/min) = Weight (kg) x (140 - Age)/72 x serum creatinine (mg/dL)
