Scientific titleA randomised controlled phase III trial comparing hyperthermia plus mitomycin to a second course of Bacillus Calmette-Guerin (BCG) or standard therapy in patients with recurrence of non-muscle invasive bladder cancer following induction or maintenace BCG therapy
Study acronymHYMN
Study hypothesisThe proposed trial is designed to answer the question whether hyperthermia plus intravesical mitomycin (HM) is effective in patients in whom urothelial cell carcinoma (UCC) has recurred following intravesical BCG induction or maintenance therapy.

Updated 22/02/2011: the anticipated end date for this trial was updated from 01/06/2012 to 30/04/2015.
Updated 04/11/2013: the trial recruitment has been on temporary halt since 19/07/2013.
Ethics approval(s)Added 04/11/2013: NRES Committee London - Brent, 19/10/2009, REC reference number: 09/H0717/56
ConditionNon-muscle invasive bladder cancer
InterventionCurrent interventions as of 11/02/2013:
Experimental Arm: Patients will receive six weekly induction instillations of hyperthermia plus mitomycin (HM) using the Synergo® System, followed by a 6 week pause and a cystoscopy assessment. If disease free then they will proceed to maintenance HM consisting of one instillation of HM every 6 weeks for the first year and one instillation every 8 weeks for the second year, with further treatment in those disease-free at 24 months at the discretion of the clinician.

Each instillation is divided into two 30 minute cycles each with 20 mg mitomycin dissolved in 50 ml of sterile water. Bladder hyperthermia (42 +/-2°C) will be delivered in combination with each instillation of mitomycin in accordance with the manufacturer's operational guidelines. At the end of the treatment the suspension should be maintained in the bladder for as long as possible up to a maximum of two hours.

Control Arm of patients who failed previous induction BCG: Patients will receive a second course of BCG therapy (BCG2)* (1). This will consist of six consecutive weekly instillations of BCG followed by maintenance therapy. Maintenance consists of three consecutive weekly instillations of BCG at 3, 6, 12, 18 and 24 months following the start of the BCG2 course, with further treatment for those disease-free at 24 months at the discretion of the clinician.

For each instillation:
Bacillus Calmette-Guérin reconstituted with normal saline to a total of 50ml instillation volume. The suspension will be instilled in the bladder and maintained for as long as possible up to two hours.

OR

Control Arm of patients who failed previous maintenance BCG: Patients will receive institutional standard treatment* (1) the best standard therapy for BCG-failure chosen at the discretion of the treating clinician on a case-by-case basis and which have been defined prior to patient randomisation.
Standard treatment can include:
1. Intravesical mitomycin (This may be given via Electromotive Drug Administration)
2. Intravesical epirubicin alone
3. Intravesical Gemcitabine alone - with approval for its use in NMIBC at your centre as it is not currently licensed in this indication
4. Intravesical BCG alone (concentration and schedule may differ from BCG2 treatment)
5. Intravesical BCG plus Interferon alpha (INFa) with prior approval for its use in NMIBC at your centre as it is not currently licensed in this indication
6. Active monitoring with 3-monthly white-light or PDD cystoscopies and urine cytology tests followed by transurethral resection if a bladder tumour is detected

The dosing regime and duration of treatment will be according to local practice and defined prior to patient randomisation.

* BCG is the standard therapy for recurrent NMIBC. However if the patient has already received induction and maintenance BCG prior to entering the trial it may not be beneficial for them to receive further BCG. Therefore if the patient has received BCG maintenance previously and is allocated to the control arm they will receive the standard therapy for BCG failure as defined by their treating centre.
(1) Note: A small proportion of patients experience intolerance to BCG during induction therapy and these patients will not benefit from further BCG treatment. In these cases, patients will be randomised between Hyperthermia plus mitomycin and Institutional Standard.

Maintenance consists of three consecutive weekly instillations of BCG at 3, 6, 12, 18 and 24 months following the start of the BCG2 course, with further treatment for those disease-free at 24 months at the discretion of the clinician.

For each instillation:
81 mg BCG, Connaught strain or Tice strain (12.5 mg per instillation), reconstituted with normal saline to a total of 50 ml instillation volume. The suspension will be instilled in the bladder and maintained for as long as possible up to two hours.

OR

Control Arm of patients who failed previous maintenance BCG: Patients will receive institutional standard treatment* that is currently used by the treating investigators' hospital and which have been defined prior to patient recruitment. Standard treatment can include:
1. Intravesical BCG plus Interferon alpha (INFa)
2. Intravesical mitomycin (This may be given via Electromotive Drug Administration)
3. Intravesical epirubicin

The dosing regime and duration of treatment will be according to local practice and defined prior to patient randomisation.

Primary outcome measureCurrent primary outcome measures as of 11/02/2013:
1. Disease-free survival. For patients without CIS at baseline and those with CIS at baseline but not at the 3-month surveillance visit, this is defined as the interval in whole days between the date of randomisation into the trial and the earliest of date of detection of recurrent disease, or date of death from any cause. For patients with CIS at baseline and at the 3-month surveillance visit, this is defined as the interval in whole days between the date of randomisation and the date of their 3-month surveillance visit. Disease recurrence is defined as the presence of urothelial cell carcinoma or positive cytology. Disease progression is defined as T2 disease or evidence extravesical disease. For those patients who do not have recurrent disease or die during the course of the trial, disease-free survival times will be censored at the last follow-up date. Patients who experience a distant upper-tract recurrence will be censored at the last available assessment. Disease-free survival will be followed-up for 2 years from the first treatment.
2. Complete-response rate at 3 months. For patients with CIS at randomisation, complete response at 3 months is defined as absence of visible tumour recurrence at cystoscopy, negative cytology and no evidence of CIS on random (4 quadrant) biopsy of the bladder.

Previous primary outcome measures until 11/02/2013:
1. Disease-free survival. Defined as the interval in whole days between the date of randomisation into the trial and the earliest of date of detection of recurrent disease, or date of death from any cause. This will also include the interval in whole days between the date proved tumour free (by cystoscopy, negative cytology and biopsy) and the earliest of date of detection of recurrent disease, or date of death from any cause in patients with CIS at randomisation. Disease recurrence is defined as the presence of urothelial cell carcinoma or positive cytology. Disease progression is defined as T2 disease or evidence extravesical disease. For those patients who do not have recurrent disease or die during the course of the trial, disease-free survival times will be censored at the last follow-up date. Patients who experience a distant upper-tract recurrence will be censored at the last available assessment. Disease-free survival will be followed-up for 2 years from the first treatment.
2. Complete-response rate at 3 months. For patients with CIS, complete response at 3 months is defined as absence of visible tumour recurrence at cystoscopy, negative cytology and no evidence of CIS on random (4 quadrant) biopsy of the bladder.
Secondary outcome measures1. Progression-free survival. Defined as the interval in whole days between the date of randomisation into the trial and the earliest of date of detection of disease progression, or date of death from any cause. Disease progression is defined as stage T2 disease or greater confirmed by histopathology following TUR (>=pT2). For those patients who do not experience disease progression or die during the course of the trial, progression-free survival times will be censored at the last follow-up date. Patients who experience a distant upper-tract recurrence will be censored at the last available assessment.
2. Overall survival. Defined as the interval in whole days between the date of randomisation into the trial and date of death from any cause; patients who do not die during the course of the trial will be censored at the last follow-up date.
3. Disease-specific survival. Defined as the interval in whole days between the date of randomisation into the trial and date of death due to bladder cancer. Patients who do not die during the course of the trial will be censored at the last follow-up date. Patients who die of other causes will be censored at date of death due to other cause.
4. Recurrence-free survival. Recurrence-free survival will be measured in patients with papillary disease only. It is defined in the same way as disease-free survival, with the important distinction that CIS at the first three-month post-treatment visit will not be included as an event, but rather considered a treatment failure and will be censored. Patients who entered with CIS, became negative at first control, will be also followed up for recurrence free from first control.
5. Safety and tolerability of HM. Safety and tolerability will be reported in terms of the frequency, severity and nature of adverse events, and the treatment received.
6. Quality of life. Quality of life will be assessed at trial entry and every three months using the questionnaires European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire for Cancer patients (EORTC QLQ-C30), EORTC-QLQ-BLS24 (a 24-item questionnaire for patients with superficial bladder cancer) and Euroqol EQ-5D.
7. Cost effectiveness. Patient costs will be calculated and cost-effectiveness assessed. The economic analysis will be based on both a principal outcome cost-per-survivor (disease-free) at 24 months; and a secondary outcome, cost-per-QALY.

All secondary outcomes will be followed-up for 2 years from first treatment.

Reason abandoned (if study stopped)Recruitment into the trial was temporarily halted on 19th July 2013 and later terminated on 7th October 2013 at the joint request of the independent Data Monitoring (DMC) and Trial Steering Committees (TSC) following concern identified by the DMC that hyperthermia treatment may have led to misinterpretation of the pathology, particularly for participants with carcinoma in situ (CIS) at trial entry. The joint DMC/TSC decided to close the trial following their request for a central pathology review for participants who failed to respond to treatment or recurred on treatment and updated statistical analysis of the trial data. In the intervening period the TSC recommended that all trial participants remain on trial treatment.
