New radioactive drug aims to shrink hard-to-treat prostate cancer
NCT ID NCT07537010
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early study tests a new drug called 3D1015 in men with a type of advanced prostate cancer that no longer responds to hormone therapy. The drug delivers radiation directly to cancer cells. The main goals are to check safety and find the best dose. About 8 men will take part.

Inclusion Criteria: 1. Capable of understanding and providing written informed consent. Willing and able to comply with all study requirements, treatments, and scheduled visits. 2. Male, aged 18 years or older. 3. Histologically or cytologically confirmed prostate adenocarcinoma. 4. Castrate levels of serum/plasma testosterone (\< 50 ng/dL or \< 1.7 nmol/L). 5. Must be 68Ga-PSMA PET/CT scan positive. 6. ECOG performance status of 0 to 2. 7. Confirmed progressive metastatic castration-resistant prostate cancer (mCRPC) that is refractory to or has progressed following prior treatments. 8. Presence of at least one metastatic lesion at baseline. 9. Adequate Organ Function. 10. Resolution of all prior treatment-related toxicities to Grade ≤ 2 (excluding alopecia). Exclusion Criteria: 1. Receipt of other systemic anti-cancer therapies within 4 weeks prior to study entry. 2. Life expectancy of \< 6 months, as assessed by the investigator. 3. A superscan as seen in the baseline bone scan. 4. Presence of clinically significant, uncontrolled, or unstable concurrent medical conditions that may compromise patient safety or study assessments. 5.
