Purpose:

This phase II trial studies how well paclitaxel and pembrolizumab works in treating patients with urothelial cancer that has not responded to previous treatment and has spread to other places in the body. Drugs used in chemotherapy, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibodies, such as pembrolizumab, may interfere with the ability of tumor cells to grow and spread. Giving paclitaxel together with pembrolizumab may be an effective treatment for urothelial cancer.


Study summary:

PRIMARY OBJECTIVES: I. To estimate the overall response rate (ORR) of pembrolizumab combined with paclitaxel. SECONDARY OBJECTIVES: I. To determine the safety and tolerability of pembrolizumab combined with paclitaxel. II. To calculate the progression-free survival (PFS) rate at 6 months. TERTIARY OBJECTIVES: I. To determine the immune effects of pembrolizumab combined with paclitaxel. II. To associate immune effects with tumor response. III. To explore changes in immune-regulatory micro ribonucleic acids (RNAs) as biomarkers of response. OUTLINE: Patients receive pembrolizumab intravenously (IV) over 30 minutes on day 1 and paclitaxel IV over 60 minutes on day 1 and 8. Treatment repeats every 21 days for 8 courses in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up within 30 days and then every 3 months for 1 year.

Inclusion Criteria: - Patients diagnosed with platinum-refractory metastatic urothelial cancer that is measureable based on Response Evaluation Criteria in Solid Tumors (RECIST) criteria 1.1.36 Platinum-refractory disease is defined as progressive disease on cisplatin or carboplatin therapy or within 12 months of prior platinum treatment (last dose.) - At least 1 prior chemotherapy regimen containing cisplatin or carboplatin - Patient must be willing to provide tissue from a newly obtained core or excisional biopsy of a tumor lesion.

Prior therapy with paclitaxel or docetaxel - Hypersensitivity to pembrolizumab, any of its excipients, paclitaxel, or any of its excipients - Diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of trial treatment - Known history of active TB (Bacillus tuberculosis) - Known additional malignancy that is progressing or requires active treatment; exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy or in situ cervical cancer - Known active central nervous system (CNS) metastases and/or carcinomatous meningitis; subjects with previously treated brain metastases may participate provided they are stable (without evidence of progression by imaging for at least four weeks prior to the first dose of trial treatment and any neurologic symptoms have returned to baseline), have no evidence of new or enlarging brain metastases, and are not using steroids for at least 7 days prior to trial treatment; this exception does not include carcinomatous meningitis which is excluded regardless of clinical stability - Active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs); replacement therapy (eg., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment - Known history of, or any evidence of active, non-infectious pneumonitis - Active infection requiring systemic therapy - History or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator - Known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial - Pregnancy or breastfeeding, or expecting to conceive or father children within the projected duration of the trial, starting with the pre-screening or screening visit through 120 days after the last dose of trial treatment - Known history of human immunodeficiency virus (HIV) (HIV 1/2 antibodies) - Known active hepatitis B (e.g., hepatitis B virus surface antigen [HBsAg] reactive) or hepatitis C (e.g., hepatitis C virus [HCV] ribonucleic acid [RNA] [qualitative] is detected) - Received a live vaccine within 30 days of planned start of study therapy - Note: Seasonal influenza vaccines for injection are generally inactivated flu vaccines and are allowed; however intranasal influenza vaccines (e.g., Flu-Mist®) are live attenuated vaccines, and are not allowed
