A Study of Pembrolizumab+ sEphB4 in Metastatic Urothelial Carcinoma

Conditions

Quick Navigation

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

sEphB-HSA may prevent tumor cells from multiplying and blocks several compounds that promote the growth of blood vessels that bring nutrients to the tumor. The purpose of this study is to evaluate the combination of Pembrolizumab + sEphB4-HSA in the population of patients with previously untreated advanced (metastatic or recurrent) urothelial carcinoma who are chemotherapy ineligible or who refuse chemotherapy.

Official Title

A Phase II Trial of Pembrolizumab as Standard of Care + sEphB4-HSA in Chemotherapy Ineligible or Chemotherapy Refusing Patients With Metastatic Urothelial Carcinoma

Standard Ages:ADULT, OLDER_ADULT

Inclusion Criteria	Exclusion Criteria
* Be willing and able to provide written informed consent/assent for the trial. * Age ≥ 18 years. * Be treatment naïve and have advanced (metastatic or recurrent) pathologically proven urothelial carcinoma. Patients progressing more than 12 months of their last dose of platinum-based neoadjuvant or adjuvant chemotherapy are eligible. * Have a performance status of 0 or 1 on the ECOG Performance Scale. * Demonstrate adequate organ function as defined in Table 1., all screening labs should be performed within 10 days of treatment initiation. * Be ineligible for chemotherapy in the assessment of the treating physician or refusing chemotherapy in frontline setting. Cisplatin ineligibility is defined as Cresatinine Clearance (CrCl) \< 60cc/min, NYHA class III hear failure, grade II neuropathy and grade II hearing loss, the latter two also apply to carboplatin-based chemotherapy. * Be approved to begin treatment with pembrolizumab per standard of care and pembrolizumab must be available to the patient. Patient must enroll on this study prior to the receiving the second dose of pembrolizumab and prior to having restaging imaging after receiving pembrolizumab. Other PD1/PDL1 antibodies are now allowed. * Have measurable disease based on RECIST 1.1. We request an OPTIONAL core biopsy from an accessible metastatic site after a minimum of 2 cycles of treatment AND prior to progression of disease to help the investigators better understand the activity of these drugs in tumor tissue.	* Has a known history of Human Immunodeficiency Virus (HIV) (HIV 1/2 antibodies). * Has a 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. * Has known active Hepatitis B (e.g., HBsAg reactive) or Hepatitis C (e.g., HCV RNA \[qualitative\] is detected). * Has a known history of active TB (Bacillus Tuberculosis) * Has 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. * Has a known additional malignancy that is progressing or requires active treatment. Exceptions include basal cell carcinoma potentially cured after surgery or prostate cancer that is under control by hormonal agents. * Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Treated brain metastases are allowed. * Is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the trial, starting with the screening visit through 120 days after the last dose of trial treatment. * Has New York Heart Association (NYHA) class 3 or 4, myocardial infarction, acute coronary syndrome, diabetes mellitus with ketoacidosis or chronic obstructive pulmonary disease (COPD) requiring hospitalization in the preceding 6 months; or any other intercurrent medical condition that contraindicates treatment with sEphB4HSA or pembrolizumab or places the patient at undue risk for treatment related complications. * Has 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. * Uncontrolled hypertension is excluded- systolic blood pressure \>140mmHg or diastolic \>90mmHg. Patients experiencing white coat hypertension the office, may be considered eligible if blood pressure log at home is within acceptable limits AND upon review and agreement from the Sponsor.
