A Multicenter Prospective Phase II Study of Modified FOLFIRINOX for 1st Line Treatment for Advanced Urachus Cancer

Study Overview
=================
Brief Summary
-----------------
This study aims to assess objective response rate of modified FOLFIRINOX in advanced urachaus cancer. Patients with locally advanced, recurrent, or metastatic urachal carcinoma of bladder, urachal will be enrolled this study. Modified version of FOLFIRINOX(Oxaliplatin 85 mg/m 2, Leucovorin 400mg/m2 , irinotecan 150mg/m2 and 5-FU 2400mg/m2) with prophylactic pegateograstim will be continued till progression, unacceptable toxicity, or till 12 cycles (24 weeks). Study drugs can be administered after 12 cycles to the subjects with benefit from study medication. Response evaluation will be done every 6 weeks.

Eligibility Criteria
-----------------
Inclusion Criteria: Histologically confirmed adenocarcinoma of bladder/urachal remnant that is clinically consistent with urachal cancer. Origin in the anterior wall or dome of the bladder Predominant invasion of muscularis or deeper tissues No obvious origin from the overlying urothelium (relative normal-looking urothelial mucosa) No primary adenocarcinoma elsewhere Patients with locally advanced, recurrent, or metastatic disease not amenable to surgery, radiotherapy, or combined modality therapy with curative intent No prior systemic therapy for advanced urachal cancer. For recurrent disease, previous 5-FU, oxaliplatin, or irinotecan chemotherapy as neoadjuvant and/or adjuvant aim is allowed if it ended more than 6 months before enrollment.

Exclusion Criteria: Age > 65 Previous radiotherapy to the only measurable lesion: but previous radiotherapy will be permitted unless the lesion is the only measurable lesion Uncontrolled CNS metastasis (brain and/or leptomeningeal metastasis) Grade 2 or more peripheral neuropathy Diagnosis of any serious secondary malignancy within the last 2 years, except for adequately treated basal cell or squamous cell carcinoma of skin, or in situ carcinoma of cervix uteri or prostate cancer and curatively treated thyroid cancer of any stage. Pregnancy or breast feeding, or intention of becoming pregnant during study treatment or within 6 months after final dose Other severe acute or chronic medical or psychiatric condition Chronic diarrhea Clinically significant cardiac disease (heart failure, coronary artery disease, and/or arrhythmia) Hypersensitivity to study medication treatment with a prohibited medication or anticipation of need for prohibited medication ( section 5.5 )
