Smart bomb for kidney cancer: imaging and radiation combo targets tough tumors
NCT ID NCT07688187
First seen Jul 07, 2026 · Last updated Jul 08, 2026 · Updated 1 time
Summary
This trial tests a two-part approach for advanced clear cell kidney cancer that has stopped responding to standard treatments. First, an imaging injection (PD-32766D) lights up cancer cells that have a specific marker (CA9). If the scan shows the marker is present, participants then receive up to six cycles of a radioactive therapy (PD-32766T) designed to deliver radiation directly to those cancer cells. The study aims to find a safe dose and see whether the treatment can shrink tumors.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- PD-32766D (imaging agent) and PD-32766T (radioactive peptide therapy)
- What this could lead to
- If successful, this could offer a new targeted treatment option for people with advanced kidney cancer who have run out of standard therapies.
- What could go wrong
- This is an early-phase trial with a small number of participants, so the treatment may not prove effective or safe. Radioactive therapy carries risks of side effects like damage to healthy tissues.

Inclusion Criteria: 1. Male or female participants aged ≥18 years. 2. Participants with confirmed diagnosis of ccRCC will be included based on the following characteristics: * Histological confirmed locally advanced, unresectable, or metastatic ccRCC, after all available standard therapy. * Presence of evaluable disease by Response Evaluation Criteria In Solid Tumors (RECIST) guideline (defined by RECIST v1.1). 3. Presence of positive tumor uptake 4. Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 to 1. 5. The participant's with adequate organ function 6. Life expectancy of at least 12 weeks as assessed by the Investigator. Exclusion Criteria: 1. Concurrent serious (as determined by the Investigator), uncontrolled medical conditions, or life-threatening or other significant comorbid conditions. 2. Any chemotherapy, radiotherapy, immunotherapy, major surgery, biologic, investigational or hormonal therapy for treatment of solid tumors within 28 days. 3. Participants who have not had resolution of clinically significant toxic effects of prior systemic cancer therapy, surgery, or radiotherapy. 4. Administration of a radiopharmaceutical with therapeutic intent within a period of 6 months. 5. Any previous CA9 targeting treatment. 6. Known hypersensitivity to the active substance or to any of the excipients of the PD-32766D and or T. 7. Clinically unstable CNS tumor at the time of screening. 8. History of bowel perforation or bowel infarction, history of active stomach or duodenum ulcer or fistula in the last 2 years, history of gastroesophageal reflux disease or enterocolitis Grade ≥3 according to NCI-CTCAE and/or known active gastrointestinal infection, any unresolved prior radiation-induced gastrointestinal injury. 9. Acute infection requiring IV antibiotics, antivirals, or antifungals within 14 days prior to the initiation of treatment (oral treatment are allowed). 10. Pregnant or breastfeeding women. 11. Known active infection with human immunodeficiency virus (HIV), hepatitis C virus (HCV), or hepatitis B virus (HBV). 12. Have been diagnosed with another primary malignancy. 13. Have significant, uncontrolled, or active cardiovascular disease 14. Bladder outflow obstruction or unmanageable urinary incontinence. 15. Inflammatory bowel disease (e.g., Crohn's disease, ulcerative colitis). 16. Any major surgery within 12 weeks before enrolment. 17. History of psychiatric illness or social situations likely to interfere with ability to comply with protocol required assessment or give informed consent.
