Renal Retention in High Grade Upper Tract Urothelial Cancer
What this study is about
This trial will evaluate the use of combination pembrolizumab and enfortumab vedotin for patients with high grade non-metastatic (cN0/NxMx, no measurable regional lymph nodes, no metastases) upper tract urothelial cancer (UTUC), preferring to forego the usual treatment radical nephroureterectomy (RNU) surgery.
View original scientific description
This trial will evaluate the use of combination pembrolizumab and enfortumab vedotin for patients with high grade non-metastatic (cN0/NxMx, no measurable regional lymph nodes, no metastases) upper tract urothelial cancer (UTUC), preferring to forego standard of care radical nephroureterectomy (RNU) surgery. Currently these patients would not be suitable candidates for neoadjuvant trials, as the patients intention is to forego surgery.
Interventions
DRUG
Enfortumab vedotin
Enfortumab vedotin 1.25mg/kg on Days 1 and 8 every 3 weeks for up to 35 weeks (each cycle = 21 days)
DRUG
Pembrolizumab
Pembrolizumab 200mg on Day 1 every 3 weeks for up to 35 weeks (each cycle = 21 days)
Primary outcome measures
Event free survival (EFS)
Time frame: 12 months
Time to relapse or death based on 12 months.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Male/female participants who are at least 18 years of age on the day of signing informed consent with histologically confirmed diagnosis of histologically documented, high grade upper tract urothelial cancer, (UTUC can be diagnosed by direct visualization and biopsy, or by 3 dimensional imaging and positive urine cytology) will be enrolled in this study. 2. Patients must refuse definitive radical nephroureterectomy (RNU), or be medically ineligible for surgery. To be medically ineligible, patients must, in the opinion of the clinical team, be at high risk of complications intra or perioperative which would adversely impact morbidity and mortality, including risk of CKD and ESRD. 3. Subjects must not have received prior systemic therapy for locally advanced or metastatic urothelial carcinoma (in other locations such as the bladder or contralateral ureter or renal pelvis) with the following exceptions: 1. Subjects who received neoadjuvant chemotherapy with rec

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
