研究概览
简要总结
This study will be undertaken to evaluate the feasibility of replacing systemic Androgen Deprivation Therapy (ADT) with targeted local delivery of an anti-androgen agent alone in patients in whom ADT + radiation therapy is indicated for the treatment of localized prostate cancer.
详细描述
This study is a prospective, single-center, single-arm feasibility study. Up to 20 participants will be recruited to assess the safety and patient tolerance of Biolen for the localized delivery of bicalutamide into the prostate when delivered with radiotherapy.
At baseline, patients will undergo multiparametric MRI of the prostate. Study participants will have placement of the drug eluting Biolen implants. At the 8 week timepoint, participants will undergo repeat multiparametric MRI.
Participants will receive standard of care radiation therapy on weeks 9-11 and will be followed through 2 years post radiation. A third and fourth multiparametric MRI will be performed at 6 and 24 months after completion of radiation. Clinical labs and correlative sample collection and patient quality of life questionnaires will be administered at follow-up visits. Following completion of follow-up or removal from protocol, patients may be offered enrollment on long-term follow up protocols.
