Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this research study is to learn about: 1) improving control of prostate cancer using an extra high dose radiation treatment to the MRI defined high risk tumor areas, in addition to the standard radiation treatment to the rest of the prostate; 2) preserving quality of life by reducing dose to the nearby organs at risk around the prostate; and 3) establishing the relationship of pre- and post-treatment MRI to MRI-directed biopsy results at 2-2.5 years after treatment.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

LEAD RT Group

Participants in this group will receive the Lattice Extreme Ablative Dose (LEAD) radiotherapy. Radiotherapy will begin within two months of fiducial marker placement. The therapy will consist of 39 fractions over approximately 8 weeks.

Group Type EXPERIMENTAL

LEAD RT

Intervention Type RADIATION

The multiparametric-MRI (MP-MRI) defined Gross Tumor Volume (GTV) will receive 12-14 Gy on the first day of treatment and then the prostate plus proximal seminal vesicles (SV), the Clinical Target Volume (CTV)1, will receive 76 Gy in 38 fractions (Fxs) at 2.0 Gy per Fx. For High Risk patients, the distal SVs may be treated to 56 Gy in 38 Fxs or full dose (CTV2), and the pelvic lymph nodes may be treated to 56 Gy in 38 Fxs (CTV3).

HEIGHT RT Group

Participants in this group will receive the Hypofractionated Extended Image-Guided Highly Targeted (HEIGHT) radiotherapy. Radiotherapy will begin within two months of fiducial marker placement. The therapy will consist of 39 fractions over approximately 7 and a half weeks.

Group Type EXPERIMENTAL

HEIGHT RT

Intervention Type RADIATION

The MRI defined GTV(s) will receive a higher dose per day than the CTV by dose painting. The GTV(s) will receive an absolute dose of 91.2 Gy. Assuming an α/β ratio of 3.0, this would be equivalent to 98.5 Gy in 2.0 Gy fractions. The prostate plus proximal seminal vesicles (CTV1) will receive 76 Gy in 38 fractions (Fxs) at 2.0 Gy per Fx. For High Risk patients, the distal SVs (CTV2) may be treated to 56 Gy in 38 Fxs or full dose, and the pelvic lymph nodes (CTV3) may be treated to 56 Gy in 38 Fxs.
