Single-Arm Phase II Combination Study of Low-Dose Paclitaxel With Pembrolizumab in Platinum-Refractory Urothelial Carcinoma
Study Overview
Status
Conditions
Intervention / Treatment
Detailed Description
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.

- Serum total bilirubin =< 1.5 X ULN OR direct bilirubin =< ULN for subjects with total bilirubin levels > 1.5 ULN

- Female subject of childbearing potential should have a negative urine or serum pregnancy within 72 hours prior to receiving the first dose of study medication; if the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required
- Female subjects of childbearing potential should be willing to use 2 methods of birth control or be surgically sterile, or abstain from heterosexual activity for the course of the study through 120 days after the last dose of study medication; subjects of childbearing potential are those who have not been surgically sterilized or have not been free from menses for > 1 year

Exclusion Criteria:
- Currently receiving or has had treatment with an investigational agent or used an investigational device within 4 weeks of study day 1

Chemotherapy, targeted small molecule therapy, or radiation therapy within 2 weeks prior to study day 1 or who has not recovered (i.e., =< grade 1 or at baseline) from adverse events due to a previously administered agent
- Note: Subjects with =< grade 2 neuropathy are an exception to this criterion and may qualify for the study
- Note: If subject received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy
- Prior therapy with an anti-programmed cell death 1 (PD-1), anti-programmed cell death-ligand 1 (PD-L1), or anti-programmed cell death-ligand 2 (PD-L2) agent. Prior therapy with paclitaxel or docetaxel

- 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

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Overall Response Rate
Time Frame: Up to 6 months
|
The overall response rate will be performed in all patients that are evaluable for efficacy and will have one interim analysis.
Overall response is complete response (CR) = Disappearance of all target lesions (PR) = at least a 30% decrease in sum of diameters, taking as reference the baseline sum diameters; stable disease (SD) = neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference smallest sum diameters while on study; and progressive disease (PD) = at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study based on all target lesions recorded since the treatment started.
|
Up to 6 months
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Adverse Events Graded According to the National Cancer Institute Common Terminology Criteria for Adverse Events Version 4.0
Time Frame: Up to 1 year
|
All adverse events will be tabulated and presented by preferred term and/or system organ class and grade.
All deaths and serious adverse events will be tabulated.
|
Up to 1 year
|
Progression Free Survival (Kaplan Meier Method)
Time Frame: At 6 months
|
The Kaplan Meier methods will be used to estimate progression free survival.
The 6-month PFS will be compared to historical rates using a chi-square test.
Progressive disease is at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study based on all target lesions recorded since the treatment started.
The sum must also demonstrate an absolute increase of at least 5 mm.
(Note: the appearance of one or more new lesions is also considered progression)
|
At 6 months
