Treatment of Locally Recurrent Prostate Cancer

This is a multi-center clinical study enrolling up to 12 participants . The primary objective of the study is to evaluate the safety of Alpha DaRT for the treatment of locally recurrent prostate cancer . The secondary objectives of the study is to evaluate the efficacy of the Alpha DaRT sources in locally recurrent prostate cancer patients assessed by biochemical and clinical evaluation of disease progression as well as overall survival

This study will be a prospective, interventional, open label, single arm, multiple center study to assess the safety efficacy of Alpha DaRT . Eligible patients with Locally Recurrent Prostate Cancer will be categorized into the study. The "Diffusing Alpha-emitter Radiation Therapy (DaRT)", based on the interstitial intratumoral placement of an encapsulated Radium-224 source (3.7 days half-life), is described in this study. These sources release short-lived alpha-emitting atoms into the tumor microenvironment by recoil. DaRT seeds will be inserted into the tumor according to a pre-determined plan.The delivery of the DaRT Sources into the prostate tumor is done by using the Alpha DaRT Alpha Prostate Applicator.
