This is a pre-surgical study involving subjects with muscle invasive bladder cancer, or urothelial cancer, who are candidates for neoadjuvant therapy. It is is a two-part trial with a one-arm phase Ib portion followed by a two-arm phase II portion. The study treatment is stratified into two cohorts based on cisplatin eligibility.

Brief Title
Neoadjuvant Pembrolizumab in Combination With Gemcitabine Therapy in Cis-eligible/Ineligible UC Subjects
Official Title
Phase Ib/II Study of Neoadjuvant Pembrolizumab With Gemcitabine-Cisplatin (Cisplatin-Eligible) or Gemcitabine (Cisplatin-Ineligible) in Subjects With T2-4aN0M0 Urothelial Cancer: HCRN GU14-188
Brief Summary
This is a pre-surgical study involving subjects with muscle invasive bladder cancer, or <br /> urothelial cancer, who are candidates for neoadjuvant therapy. It is is a two-part trial with <br /> a one-arm phase Ib portion followed by a two-arm phase II portion. The study treatment is <br /> stratified into two cohorts based on cisplatin eligibility.
Detailed Description
OUTLINE: This is a multi-center study.
INVESTIGATIONAL TREATMENT:
Phase Ib Dose-Finding Cohort I Cisplatin-Eligible:
Phase Ib is a 3+3 design for the cisplatin-eligible group only. Cisplatin-eligible subjects
receive: gemcitabine 1000mg/m2 IV D1 and D8 every 21 days repeated for 4 cycles; cisplatin
70mg/m2 IV D1 and D8 every 21 days, repeated for 4 cycles. (Subjects with Ccr of 50-59 mL/min
must follow split dosing of cisplatin over two days). Pembrolizumab will be given every 3
weeks for 5 doses, with a starting dose of 200 mg. NOTE: the last dose of pembrolizumab falls
on what would be D8 of a 5th 'chemo' cycle, however gemcitabine/cisplatin is NOT GIVEN.
Phase II Arm A: Cohort I Cisplatin-Eligible:
Cisplatin-eligible subjects receive: gemcitabine 1000mg/m2 IV D1 and D8 every 21 days
repeated for 4 cycles; cisplatin 70mg/m2 IV D1 and D8 every 21 days, repeated for 4 cycles.
(Subjects with Ccr of 50-59 mL/min must follow split dosing of cisplatin over two days).
Pembrolizumab at recommended phase II dose (RP2D) is given every 3 weeks for 5 doses starting
with C1D8. NOTE: the last dose of pembrolizumab falls on what would be day 8 of a 5th 'chemo'
cycle, however gemcitabine/cisplatin is NOT GIVEN. Cohort I treatment with gemcitabine and
cisplatin will continue for a maximum of 4 cycles (cycle = 21days).
Phase II Arm B: Cohort II:
Cisplatin-ineligible subjects receive gemcitabine 1000mg/m2 IV D1, D8 and D15 every 28 days,
repeated for 3 cycles. Pembrolizumab at RP2D is given every 3 weeks for 5 doses starting with
C1D8. NOTE: due to the timing of gemcitabine cycles every 4 weeks, and every three week
dosing of pembrolizumab, there are two doses of pembrolizumab given during cycle 2: D1 and
D22. Additionally, the last dose of pembrolizumab falls on what would be D8 of a 4th 'chemo'
cycle; however gemcitabine is NOT GIVEN. Cohort II treatment with gemcitabine will continue
for a maximum of 3 cycles (cycle = 28 days)
Subjects will then have surgery to remove their primary tumor within 2-7 weeks after their
last dose of neoadjuvant therapy.
Eastern Cooperative Oncology Group (ECOC) performance status: 0-1 for cisplatin-eligible
subjects; 0-2 for cisplatin-ineligible subjects.

Treatments and/or Procedures
Pembrolizumab
In this dose-finding cohort, pembrolizumab (MK-3475) will be administered (cisplatin-eligible patients only) at starting dose 200mg IV every 21 days for 4 cycles to determine RP2D. Once MTD is established in phase Ib, pembrolizumab will be administered on phase II cohorts I and II at RP2D every 21 days for 5 cycles.
Gemcitabine
For cisplatin-eligible patients on phase Ib and phase II cohort 1, gemcitabine 1000mg/m2 IV, D1 and D8 every 21 days for 4 cycles. For cisplatin-ineligible patients on phase II cohort II, gemcitabine 1000mg/m2 will be administered D1, D8 and D15 every 28 days for 3 cycles.
Cisplatin
For cisplatin-eligible patients, cisplatin 70mg/m2 IV will be administered D1 every 21 days for 4 cycles.
Consolidative surgery
Following completion of treatment, subjects will then have surgery to remove their primary tumor within 2-7 weeks after their last dose of neoadjuvant therapy.
Outcome Measures
Outcome measures are the tests that investigators perform to prove whether or not a treatment being tested in a clinical trial is having any effect.
Primary

To assess PaIR rate, i.e., ypT0, Tis, Ta, T1 ypN0, per RECIST 1.1 criteria, at radical cystectomy, following combination therapy.
Secondary
Relapse-Free Survival (RFS)
Determine relapse free survival (RFS) 18 months post completion of therapy, per RECIST 1.1 criteria
Secondary
Overall Survival (OS)
After 18 months, patients will be followed for survival every 6 months for 5 years from end of treatment.
Secondary

For subjects who have tumors limited to the upper tract including renal pelvis or ureters, muscle invasive disease does not need to be pathologically proven, and a CT urogram must be performed (MRI is not acceptable to meet this criterion). To be eligible, subjects with upper tract tumors of the renal pelvis and ureter(s) must meet a high risk assessment defined as: tumor ≥ 1cm and/or hydronephrosis and/or high grade pathology and/or multifocal disease, where a radical NU approach to treat localized disease is warranted. - Histology must be urothelial carcinoma (transitional cell carcinoma) or urothelial carcinoma with mixed histology/features. - Clinical stage cT2-4aN0M0.

NOTE on surgical intent: Criteria for acceptable surgical risk are not defined and per treating urologist. Minimum guidance on surgical intent includes subjects who do not have significant cardiovascular disease such as NHYA class III or IV heart failure, unstable arrhythmias or angina, active CAD, and/or EF<25%. Specific diagnostic testing to determine surgical intent is not required and per treating urologist or oncologist discretion. - Having an archived tumor block available to submit 11 unstained slides for PD-L1 expression, basal and luminal subtype analysis is MANDATORY for subjects with bladder cancer (optional for those with tumors limited to the upper tract if sufficient tissue is not available). If slides are not available, a biopsy is strongly encouraged to obtain tissue for submission (See Study Procedures Manual for collection, labeling and shipping instructions). - Subjects on full dose anticoagulants must be on a stable regimen of warfarin or low molecular weight heparin (LMWH) for at least two weeks. - Demonstrate adequate organ function as defined below: All screening labs should be performed within 28 days of study registration. - System - Hematological - Absolute neutrophil count (ANC): ≥1500 / mcL - Absolute lymphocyte count: ≥350 mcL - Platelets: ≥100,000/mcL - Hemoglobin: ≥9 g/dL or ≥5.6 mmol/L - Renal ---Measured or calculated creatinine clearance: ≥30 mL/min - Hepatic - Serum total bilirubin: ≤1.25 X ULN OR ≤2.5xULN for subjects with Gilbert's disease - AST(SGOT) and ALT(SGPT): ≤2 X ULN - Coagulation - International Normalized Ratio (INR) or Prothrombin Time (PT): ≤1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants - Activated Partial Thromboplastin Time (aPTT): ≤1.5 X ULN unless subject is receiving anticoagulant therapy and as long as PT or PTT is within therapeutic range of intended use of anticoagulants - Female subjects of childbearing potential must have a negative urine or serum pregnancy test within 72 hours prior to study registration.

NOTE: Subjects of childbearing potential are those who have not been surgically sterilized or have not been free from menses for > 1 year. - Male subjects must agree to use a barrier method of male contraception starting with the first dose of study therapy and through 120 days after the last dose of study therapy. COHORT I - CISPLATIN-ELIGIBLE: In addition to the inclusion criteria listed above, Cohort I subjects must satisfy all of the following criteria: - Glomerular filtration rate (GFR) or creatinine clearance (Ccr) ≥ 50 mL/min. (24 hour urine preferred). The cisplatin dose will be split over two days for values between 50-59 mL/min - ECOG PS 0, 1 (and not 2) - Hearing impaired ≤ grade 1 (may or may not be enrolled in a monitoring program) - Peripheral neuropathy ≤grade 1 COHORT II - CISPLATIN-INELIGIBLE: In addition to the inclusion criteria listed above, Cohort II subjects must also meet any ONE of the following criteria: - GFR or Ccr: 30-49 (24 hour urine preferred). - ECOG PS 2 - Hearing impaired ≥grade 2 as assessed by treating physician (may or may not be enrolled in a monitoring program). - Peripheral neuropathy of Grade 2-4 Exclusion Criteria: Subjects may not have any of the following: - A non-surgical approach recommended by the treating urologist due to any reason.
