Study Description

Brief Summary:

This is a phase 2, single arm, two-stage study of abraxane with an anti-PD1/PDL1 (pembrolizumab) in cisplatin-ineligible patients with advanced urothelial cancer.

Each cycle last 21-days. All subjects will receive pembrolizumab via IV on day 1, and abraxane via IV on Day 1 and Day 8 of each cycle. Subjects may continue to receive the study regimen until they experience disease progression or unacceptable toxicity.

Outcome Measures

Primary Outcome Measures :

1. Percentage of patients that respond to treatment [ Time Frame: 24 months post treatment ]

   The Overall Response Rate (ORR) will be the percentage of patients that achieve either complete response (CR) or partial response (PR).

   CR is defined as the disappearance of all target lesions, determined by two separate observations conducted not less than 4 weeks apart. There can be no appearance of new lesions.

   PR is defined as at least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD. There can be no appearance of new lesions.

Secondary Outcome Measures :

1. Duration of response [ Time Frame: 24 months post treatment ]

   The duration of response (DOR) is measured from the time that response (PR or CR) criteria are met until the first date that recurrent or progressive disease is objectively documented.

   CR is defined as the disappearance of all target lesions, determined by two separate observations conducted not less than 4 weeks apart. There can be no appearance of new lesions.

   PR is defined as at least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD. There can be no appearance of new lesions.

2. Progression free survival time [ Time Frame: 24 months post treatment ]

   Progression-free survival (PFS) is defined as the duration of time from start of treatment to time of progression or death.

   Progressive disease (PD) is defined as at least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started, or the appearance of one or more new lesions.

3. Median number of patients alive at 12 and 24 months [ Time Frame: 12 and 24 months post treatment ]
   Overall survival will be documented as the median number of patients alive at 12 and 24 months.
4. Median duration of therapy [ Time Frame: 24 months post treatment ]
5. Percentage of patients that completely respond to treatment [ Time Frame: 24 months post treatment ]
   The percentage of patients that achieve complete response to treatment. Complete response is defined as the disappearance of all target lesions, determined by two separate observations conducted not less than 4 weeks apart. There can be no appearance of new lesions.

• Male subjects must practice true abstinence or agree to use a condom during sexual contact with a pregnant female or a female of childbearing potential while participating in the study, during dose interruptions and for 6 months following drug discontinuation, even if he has undergone a successful vasectomy.
• Patients must have < Grade 2 pre-existing peripheral neuropathy
• Be ≥18 years of age as of date of signing informed consent
• Voluntarily agree to participate by providing written informed consent/assent for the trial

Exclusion Criteria:

• History of allogenic organ transplantation that requires ongoing use of immunosuppressive agents is NOT permitted
• Active or prior documented autoimmune or inflammatory disorders are NOT permitted
• Current or prior use of immunosuppressive medication(s) within 14 days before study treatment is NOT permitted.
• Brain metastases or spinal cord compression are NOT permitted unless they have been treated with the patient's condition being stable clinically and radiologically for 28 calendar days and off steroids for at least 14 days prior to the start of study treatment.
• Active infection including tuberculosis, hepatitis B, hepatitis C, or human immunodeficiency virus (HIV) is NOT permitted.
• Receipt of live attenuated vaccine within 30 days prior to the first study treatment is NOT permitted.

  3. Subjects (both males and female) should practice effective contraception during study and for 6 months after the last dose of study medication (Section 3.1.8 i, ii).
• Patients with biliary obstruction or biliary stent are excluded.
