Alpha Radiation Emitters Device (DaRT) for the Treatment of Non-Metastatic Locally Recurrent Prostate Cancer.

Recruiting now · Not applicable

Conditions studied: Non-metastatic Prostate Cancer, Locally Recurrent Prostate Cancer

In brief

This is a multi-center clinical study enrolling up to 10 participants. The purpose of this study is to assess the feasibility and safety of intratumoral DaRT seeds implantation for the treatment of locally recurrent prostate cancer. Secondary objectives are to 1. To evaluate feasibility of interstitial radiotherapy using DaRT seeds. Feasibility will be determined according to the rate of successful placement of DaRT seeds via imaging \[Timeframe: immediately following the insertion procedure 2. To assess the impact of DaRT seeds on patient reported quality of life.

Who can join

Age: 18 and older, up to 120. Sex: male. Healthy volunteers: not accepted.

You may qualify if…

• Histologically confirmed locally recurrent prostate adenocarcinoma cancer confined to at least 1 hemi-gland with concordant pathology and imaging findings within 6 months prior to consenting
• Targetable lesion by either PSMA PET-CT according to PERCIST v1.0 or by multiparametric MRI according RECIST v1.1
• Patient being considered for focal salvage brachytherapy
• Lesion size ≤ 3 cm in the longest diameter
• Target lesion technically amenable for full tumor coverage with the Alpha DaRT seeds
• Pre-salvage PSA level (rPSA) below <10 ng/ml
• Age ≥ 18 years old
• ECOG Performance Status Scale ≤ 2
• Subjects' life expectancy is more than 6 months
• Negative metastatic workup on at least standard imaging (CT CAP and bone scan). Other metastatic screening studies allowed in lieu of standard imaging including multiparametric MRI prostate/whole body, PSMA PET, F18 PET or Axumin PET within 3 months before visit 0
• Platelet count ≥100,000/mm3
• Subjects are willing and able to sign an informed consent form.

You may not qualify if…

• N1 or M1 disease
• Prior TURP or prostate surgery
• Inability to undergo multiparametric MRI (i.e. permanent implanted device incompatible with MRI)
• Inability to undergo general or spinal anesthesia
• Prior androgen deprivation therapy or systemic chemotherapy for prostate cancer within 3 months before visit 0.
• Previous diagnosis of other malignancy < 3 years of enrollment (excluding non-melanomatous skin cancer)
• Volunteers participating in another interventional study in the past 30 days which might conflict with the endpoints of this study or the evaluation of response or toxicity of DaRT
• High probability of protocol non-compliance (in opinion of investigator)
• Subjects not willing to sign an informed consent
• Patients with significant comorbidities that the treating physician deems may conflict with the endpoints of the study (e.g., poorly controlled autoimmune diseases, vasculitis, etc.)
