Piflufolastat F 18 PET/CT for Kidney Cancer
(HARRIER Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores a new imaging technique called piflufolastat F 18 PET/CT to improve the diagnosis of kidney cancer, specifically clear cell Renal Cell Carcinoma (ccRCC). Researchers aim to determine the optimal dose and timing for the scan and assess its effectiveness in detecting cancer that has spread beyond the kidney. This trial is suitable for individuals with ccRCC who have suspected or known metastatic cancer, or those at high risk, such as patients who have recently undergone kidney surgery and are concerned about cancer spreading. Participants will receive an injection, followed by scans, and will be monitored for any reactions or disease progression. As a Phase 2 trial, this research measures the effectiveness of the imaging technique in an initial, smaller group, offering participants an opportunity to contribute to advancements in cancer diagnosis.
Do I need to stop my current medications for the trial?
Yes, if you are on active systemic therapy for metastatic kidney cancer, you will need to stop it and wait for a 30-day period (or 12 weeks if it's immunotherapy) before participating in the trial.
What prior data suggests that the piflufolastat F 18 PET/CT imaging technique is safe for diagnosing kidney cancer?
Research has shown that piflufolastat F 18 is generally safe for use in PET scans. Studies have used this imaging agent to help detect and understand kidney cancer. The FDA has not requested additional safety tests for this agent, indicating it is usually well-tolerated by patients.
Piflufolastat F 18 attaches to a protein often found on cancer cells, aiding doctors in locating cancer within the body. While further testing continues, previous studies have not raised new safety concerns, which is reassuring. Participants in this trial will have their health monitored closely to ensure safety.12345Why are researchers excited about this trial?
Unlike the standard treatments for kidney cancer, which typically include surgery, targeted therapies, and immunotherapy, Piflufolastat F 18 offers a unique and non-invasive imaging approach. Researchers are excited because this treatment uses a radiotracer that targets specific cancer cells, allowing for highly precise PET/CT scans. This precision helps in detecting metastatic lesions more accurately and could potentially lead to better treatment planning and outcomes for patients. Additionally, Piflufolastat F 18's ability to provide clear imaging in a short time frame is a significant advantage over traditional imaging methods.
What evidence suggests that this imaging technique is effective for diagnosing kidney cancer?
Research has shown that piflufolastat F 18 PET/CT scans are promising for detecting kidney cancer that has spread beyond the kidney. This trial includes a Phase 2 dose optimization arm to determine the optimal dose and scan timing window for piflufolastat F 18 PET/CT. Following this, a Phase 3 single-arm expansion will further evaluate its effectiveness. This imaging method helps doctors identify where the cancer has spread, allowing for more effective treatment planning. While specific data on piflufolastat F 18 is still being collected, similar PET/CT scans have successfully detected cancer in other types. They excel at identifying cancerous areas that other scans might miss, enabling doctors to make better decisions about cancer management.12567
Are You a Good Fit for This Trial?
This trial is for adults over 18 with clear cell Renal Cell Carcinoma (ccRCC), either newly diagnosed or post-surgery with suspected metastases. Participants should be able to follow the study plan, have a life expectancy of at least 6 months, and an ECOG status of 0-2, indicating they are fully active or ambulatory.Inclusion Criteria

Single-arm Expansion
Phase 3 involves assessing the diagnostic performance of piflufolastat F 18 PET/CT in 274 patients.
Follow-up
Participants are monitored for safety and effectiveness after treatment, including assessment of adverse events and clinical management impact.
What Are the Treatments Tested in This Trial?
Interventions
- Piflufolastat F 18
Trial Overview
The trial tests piflufolastat F 18 PET/CT scans in diagnosing and assessing the spread of ccRCC. It will determine the best dose and timing for the scan and evaluate its ability to detect metastatic lesions, potentially influencing patient management.
How Is the Trial Designed?

Treatment groups
Experimental Treatment
Phase 3 will commence once the optimal dose and optimal timing window from Phase 2, dose optimization, are determined. Phase 3 will be a single-arm study that will enroll 274 patients with radiographically suspected metastatic disease by conventional imaging or at high risk for metastatic ccRCC at the time of enrollment.
The dose-optimization, or Phase 2, part of the study will enroll 6-12 ccRCC patients, with at least one metastatic lesion identified by conventional imaging at the time of enrollment, to define the optimal dose and scan timing window for piflufolastat F18 PET/CT. Piflufolastat F18 will be administered at a target dose of 9 mCi \[+/-1 mCi\]) after which patients will be scanned at 60-90 minutes and again at 3-4 hours.
