Scientific titleA randomised phase II trial of Prostate and pelvIs Versus prOsTate Alone treatment for Locally advanced prostate cancer
Study acronymPIVOTAL
Study objectivesPIVOTAL is a non-comparative randomised study which aims to determine the feasibility and toxicity of treating locally advanced prostate cancer with escalated doses of radiotherapy to the prostate and pelvic nodes using intensity modulated radiotherapy (IMRT).
Ethics approval(s)MREC, 25/08/2010, ref: 10/H1208/54
Health condition(s) or problem(s) studiedTopic: National Cancer Research Network; Subtopic: Prostate Cancer; Disease: Prostate
Intervention1. Pelvis and prostate IMRT: 74 Gray to prostate and 60 Gray to pelvis in 37 fractions over 7.5 weeks
2. Prostate alone IMRT: 74 Gray in 37 fractions over 7.5 weeks

Follow-up length: 24 months
Study entry: single randomisation only
Intervention typeOther
Primary outcome measureAcute gastrointestinal (GI) Radiation Therapy Oncology Group (RTOG) grade greater than or equal to 2 toxicity, measured 18 weeks from start of radiotherapy
Secondary outcome measures1. Biochemical progression, measured throughout follow up
2. Compliance with dose volume constraints, measured throughout follow up
3. Disease-specific survival, measured throughout follow up
4. Local progression, measured throughout follow up
5. Lymph node (regional) progression, measured throughout follow up
6. Overall survival, measured throughout follow up
7. Patient reported outcomes, measured at baseline (pre-randomisation and pre-radiotherapy treatment), week 10, week 18 and at 6, 12, 18 and 2 years
8. Patterns of recurrence, measured throughout follow up
9. Time to distant progression, measured throughout follow up
Overall study start date01/03/2011
Completion date28/02/2013

Eligibility

Participant type(s)Patient
Age groupAdult
Lower age limit18 Years
SexMale
Target number of participantsPlanned sample size: 110; UK sample size: 110
Key inclusion criteria1. Histologically confirmed, non-metastatic adenocarcinoma of the prostate, previously untreated (other than by neoadjuvant hormonal treatment)
2. National Collaborative Cancer Network locally advanced disease (T3b or T4) or estimated risk of pelvic lymph node involvement greater than or equal to 30% and either:
2.1. Gleason 9 or 10, or
2.2. Gleason 8 and one other high risk feature (T3 disease or prostate specific antigen [PSA] greater than 20), or
2.3. Gleason 7 and 2 high risk features (T3 disease and PSA greater than or equal to 30)
3. World Health Organization (WHO) performance status 0 or 1
4. Normal blood count (Hb greater than 11 g/dl, white blood cell count [WBC] greater than 4000/mm3, platelets greater than 100,00/mm3)
5. Hormonal therapy for 6 - 9 months duration prior to proposed radiotherapy treatment and PSA less than 4 ng/ml prior to randomisation
6. Testosterone level less than 20 ng/dL (0.7 nmol/L)
8. Patients must be prepared to attend follow up. All patients participating in the Patient Reported Outcomes (PRO) Study must have adequate cognitive ability to complete the PRO questionnaires.
9. Written informed consent
10. Male, aged 18 years or older
Key exclusion criteria1. Prior pelvic radiotherapy
2. Prior major pelvic surgery (e.g. colectomy, colostomy, cystectomy, prostatectomy)
3. Radiologically suspicious (short axis diameter greater than or equal to 1.0 cm unless biopsied and negative) or pathologically confirmed lymph node involvement
4. Life expectancy less than 5 years
5. Castrate resistant prostate cancer (rising PSA after LHRHa and anti-androgen)
6. Previous active malignancy within the last 5 years other than basal cell carcinoma
7. Co-morbid conditions likely to impact on the decision to treat with radiotherapy (e.g. previous inflammatory bowel disease, previous colo-rectal surgery, significant bladder instability or urinary incontinence)
8. Bilateral hip prosthesis or fixation which would interfere with standard radiation beam configuration

IPD sharing plan summaryAvailable on request
Publication and dissemination planNot provided at time of registration
IPD sharing planThe datasets generated during and/or analysed during the current study are/will be available upon request. Contact details are the same as in the contact information section. Clinical data are available for sharing subject to completion of a data sharing application form, approval by the trial oversight committees and completion of a data sharing agreement. As part of the review the trialists would consider whether the existing trial consent covers the application, what anonymisation will be required and whether separate ethics approval would be required.
