Clinical trial: Buparlisib in Metastatic Transitional Cell Carcinoma of the Urothelium

Summary: The purpose of this study is to learn what effects, good and/or bad, Buparlisib has on advanced urothelial cancer. Buparlisib is a pill that works by shutting down some of the signals in cancer cells that make tumors grow. It is being tested in patients in research studies such as this one. As of 2010, more than 80 patients with various types of cancer have received treatment with Buparlisib in research studies.
  This clinical research study is divided into two parts. The goal of the first part of this study is to learn if the study drug Buparlisib can shrink or slow the growth of cancer in patients with urothelial tumors. The goal of the second part of this study is to learn if the study drug Buparlisib can shrink or slow the growth of urothelial tumors in patients known to have certain genetic alterations that cause these types of tumors. The study doctor will inform the patient which part of the study is currently enrolling participants. Participants in both parts of the study will receive the same treatment and tests.
  The safety of this drug will also be studied in both parts. The physical state, changes in the size of the tumor, and laboratory findings taken while on-study will help us decide if Buparlisib is safe and effective.


Eligibility: Inclusion Criteria:
  -  Age ≥ 18 years
  -  Karnofsky Performance Status (KPS) ≥60%
  -  Urothelial carcinoma of the bladder, urethra, ureter or renal pelvis, with histologic confirmation at MSKCC. Patients with unresected primary tumors may be enrolled as long as evidence of metastatic disease is also present.
  -  Patients must have progressive metastatic disease. Progressive disease will be defined as new or progressive lesions on cross-sectional imaging (RECIST Version 1.1).
  -  Patients must have been previously treated, as defined by the following:
  -  Patients must have received treatment with at least one prior cytotoxic chemotherapy agent but not more than four prior cytotoxic chemotherapy agents for urothelial carcinoma. Up to four prior chemotherapy agents are allowed, since conventional chemotherapy ranges from just one drug (e.g., gemcitabine) to regimens that contain four agents (e.g., M-VAC is a four-drug regimen containing methotrexate, vinblastine, doxorubicin, and cisplatin).
  The prior therapy must have consisted of at least one of the following: cisplatin, carboplatin, paclitaxel, docetaxel, or gemcitabine.
  o The prior cytotoxic agents may have been administered in the perioperative or metastatic setting and may have been administered sequentially (e.g., first-line treatment followed by second-line treatment at time of progression) or as part of a single regimen.
  -  Patients must have at least one site of measurable disease per RECIST 1.1 criteria that has not been previously irradiated. If the patient has had previous radiation to the marker lesion(s), there must be evidence of progression since the radiation.
  -  Patients enrolling in the Phase II study must have pre-treatment tumor tissue available for PI3K/Akt pathway marker analysis: One paraffin block, frozen curls or 10 freshly-prepared unstained slides from the most representative single paraffinembedded tumor tissue block should be submitted. Slides from the primary tumor are preferred. If both the primary and metastatic tumor blocks are available, 10 slides from each of the sites should be submitted. If tissue from the primary tumor is not available, a paraffin block or unstained slides from a metastatic site are acceptable. Fine needle aspirates (FNAs) have insufficient tumor tissue and are not permitted.
  -  Patients enrolling in the Expansion Cohort must have prior mutational testing demonstrating alterations within the PI3K/Akt/mTOR pathway predicted to result in pathway activation.
