Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This phase III clinical trial is designed to compare the safety of a standard pelvic external beam radiation therapy (EBRT) combined with a high dose rate brachytherapy (HDRB) boost (direct insertion of radiation source over a period of minutes via flexible needles temporarily inserted in the prostate) to a shorter course of hypofractionated dose escalation radiotherapy (larger radiation dose per daily treatment) in patients with high risk prostate cancer.
The investigators plan to recruit 296 patients across Quebec who will be randomized in either treatment plan.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This phase III clinical trial is designed to compare the safety of a conventional pelvic EBRT combined with a HDRB boost (i.e. 46 Gy in 23 fractions followed by a 15-Gy HDRB boost) to a shorter course of hypofractionated dose escalation radiotherapy (i.e. 68 Gy in 25 fractions) in patients with high risk prostate cancer. The patients will be randomized to either of the two different courses of treatment. All the patients will be also treated with hormonal therapy for a total duration of 28 months (2 months before radiation therapy (RT), 2 months during RT and for 24 months after RT). The patients will undergo different test before the treatment, such as bone scan, blood test, CT scan and bone density. The patient's follow-up will be the first month after start of RT, every 4 months for the first 2 years, then every 6 months the third year and then annually for 10 years. On every visit, the patient will undergo digital rectal examination (DRE) as well as evaluation of testosterone and prostate specific antigen (PSA) levels.
The safety of the new course of radiation therapy will be evaluated by the acute (at and before 90 days) and delayed toxicities (at 90 days, at 180 days and after) measured by Common Terminology Criteria for Adverse Events (CTCAE version 4). We will also determine Biochemical Failure Free Survival, Distant Metastasis Free Survival, Disease Specific Survival, Overall Survival and the Health-related Quality of Life using the Expanded Prostate Cancer Index Composite (EPIC). We will also monitor the development of gastrointestinal and genitourinary toxicities and establish the predictive value of PTEN deletion and TMPRSS2ETS fusion (genetic markers to predict the nature and progression of prostate tumors).
This study will be conducted through the Genitourinary Radiation Oncology Group of Quebec (GROUQ) in 12 selected radiation oncology centers. We plan to recruit 296 patients across Quebec and the recruitment should be completed within 24 months of activation.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
ADT+EBRT+ HDR brachytherapy boost
Standard fractionation radiotherapy: 46 Gy in 23 fractions (EBRT) and a 15-Gy HDRB boost in conjunction with 28 months of androgen deprivation therapy (ADT).

Hypofractionated dose escalation radiotherapy: 68 Gy in 25 fractions in conjunction with 28 months of androgen deprivation therapy (ADT).
Hypofractionated Dose Escalation Radiotherapy
Radiation therapy (higher radiation dose per treatment) will be given once a day, five days a week, over approximately 5 weeks.
Androgen deprivation therapy
28 months of androgen deprivation therapy (injections every 4 months for a total of 28 months)

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Clinical stage including at least one of the following: T3 or T4, Gleason Score \> 8, and/ or Prostate-specific antigen (PSA) \> 20 (ng/ml or μg/L).
* Pelvic and para-aortic lymph nodes must be negative on CT scan or MRI of the abdomen and pelvis performed within 12 (recommended time limit, may exceed in certain cases) weeks prior to randomization. For patients who have started androgen suppression prior to randomization, CT or MRI may be done after start of therapy, provided it is done no more than 28 days following start of androgen suppression therapy (any lymph node appearing \> 1.5 cm on CT or MRI must be histologically negative by either needle aspirate or lymph node dissection performed within 12 weeks prior to randomization).
* Investigations, including chest x-ray (CXR is recommended and not mandatory) CT scan and bone scan (with radiographs of suspicious areas) have been performed within 12 weeks (recommended time limit) prior to randomization and are negative for metastases. For patients who have started androgen suppression prior to randomization, bone scan may be done up to and including 28 days after the commencement of therapy.
* Patients will have had a PSA test done at the time of diagnosis. This PSA test could be repeated within 28 days prior to randomization. The PSA value used to confirm high risk disease and the value to be entered on the eligibility checklist must be the higher of these two values. These criteria will be the same regardless of whether or not the patient has initiated hormone therapy prior to randomization.
* The patient may have received prior androgen suppression therapy provided that androgen suppression therapy commenced no more than 28 days prior to randomization.
* The patient must not have received any cytotoxic anticancer therapy for prostate cancer prior to randomization. Patients may have received treatment with a 5-alpha-reductase inhibitor (e.g. Finasteride) for benign prostatic hypertrophy (BPH), which must have been discontinued prior to the randomization.
* ECOG performance status must be 0 or 1.
* Hematology and Biochemistry: Laboratory requirements have been done within 28-42 days prior to randomization: hemoglobin \> 100 g/L, absolute Neutrophils \> 1.5 x 109/L, platelets \> 100 x 109/L, serum creatinine \< 1.5 x ULN
Exclusion Criteria
* The presence of small-cell or transitional-cell carcinoma in the biopsy specimen.
* Patients who had previous chemotherapy for carcinoma of the prostate.
* Patients who had prior surgical treatment for carcinoma of the prostate apart from trans-urethral resection, including bilateral orchiectomy.
* Patients with any contraindication to pelvic radiotherapy: including, but not limited to, previous pelvic radiotherapy. Inflammatory bowel disease (at the discretion of the treating oncologist) or severe bladder irritability.
* Patients with serious non malignant disease resulting in a life expectancy less than 3 years.
* Other serious illness, psychiatric or medical condition that would not permit the patient to be managed according to the protocol including active uncontrolled infection and significant cardiac dysfunction. Patients with medical conditions that would contraindicate the treatment regimen outlined in the protocol \[e.g. intake of study drugs\].
* Known hypersensitivity to any protocol-indicated study medications.
* Presence of bilateral hip replacement prostheses.
* Patients with history of severe congestive heart failure will not be eligible.
* Patients with congenital long QT syndrome or patients taking Class IA, Class III or Class IC anti-arrhythmic medications will require a cardiologist's evaluation prior to eligibility assessment. Patients with cardiovascular diseases can be included as long as the benefits of androgen deprivation therapy outweigh the potential risk of cardiovascular events.
