Targeted radiation therapy for high-risk prostate cancer using advanced imaging

Single-Arm Phase II Study of PSMA PET/MR Guided Stereotactic Body Radiation Therapy With Simultaneous Integrated Boost (SBRT-SIB) for High-Intermediate and High Risk Prostate Cancer

Phase 2 Interventional Weill Medical College of Cornell University · NCT04402151

This study is testing a new type of targeted radiation therapy using advanced imaging to see if it can help men with high-risk prostate cancer have better treatment outcomes and lower chances of the cancer coming back.

What this trial studies

This clinical trial evaluates the effectiveness of PSMA PET/MR guided stereotactic body radiation therapy (SBRT) with simultaneous integrated boost for patients with high-intermediate and high-risk prostate cancer. The study aims to enroll 50 male participants who will receive personalized radiation treatment based on advanced imaging techniques that enhance tumor visualization and treatment precision. By utilizing real-time adaptive planning during radiation delivery, the trial seeks to improve clinical outcomes and reduce recurrence rates in aggressive prostate cancer cases. The approach combines novel imaging with innovative radiation technology to better target areas at risk of cancer recurrence.

Who should consider this trial

Good fit: Ideal candidates are males aged 21 and older with pathologically confirmed high-risk adenocarcinoma of the prostate.

Not a fit: Patients with evidence of metastatic disease or contraindications to the proposed treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve survival rates and reduce recurrence in patients with high-risk prostate cancer.

How similar studies have performed: While the use of PSMA PET/MR imaging is novel, similar approaches in radiation therapy have shown promise in improving treatment outcomes for localized cancers.

Eligibility criteria

Inclusion Criteria:

* Male aged 21 years or older.
* Ability to provide signed informed consent and willingness to comply with protocol requirements.
* Pathologic confirmation of high-risk adenocarcinoma of the prostate gland as follows: a. Gleason 8-10 or tertiary component 5 disease and/or b. PSA of 20 ng/ml or greater and/or c. Tumor stage of T2c or greater; OR Unfavorable intermediate risk (Gleason 4+3=7, \>50% of cores involved, or 2 or more intermediate risk factors which include Gleason 7 disease, PSA 10-20, or T2b disease)
* Participants must agree to use an acceptable form of birth control and utilize condoms for a period of seven days after each PSMA injection, if engaged in sexual activity.
* No evidence of metastatic disease, including pelvic lymph nodes.

Exclusion Criteria:

* Clinical and/or technical factors that would compromise statistical analysis of the PET and/or MR.
* Contraindications to PSMA IV administration
* Contraindications to prostate SBRT (history of transurethral resection of prostate; prostate size greater than 150 cc; AUA score greater than 20; history of prior radiation to the prostate)
* Other unspecified reasons that, in the opinion of investigators, make the subject unsuitable for enrollment
