Adjuvant Sequential Intravesical BCG (Bacillus Calmette-Guérin) and Electromotive Mitomycin-C (EMDA/MMC) After Transuretheral Resection (TUR) in Patients With Primary High Risk Non-Muscle Invasive Transitional Cell Carcinoma of the Bladder
The primary objective of the study is to assess the bladder cancer recurrence free rate,
according to a phase II pilot study, of intravesical instillation of sequential BCG and
EMDA/MMC after TUR. The study is designed as a one-sample investigation: the outcome measure
is disease recurrence rate. Follow up will continue up to 5 years.
For sample size determination, disease recurrence rate will be compared with literature data
of recurrence rate obtained in standard BCG alone administration (Lamm's protocol).

TURBT (TransUrethral Resection of Bladder Tumor)
Prior to enrolment, all patients must sign a consent form and will have a Complete Blood
Count (CBC), Basic Metabolic Panel (BMP) and a Urinalysis (UA) performed. The patients White
Blood Count (WBC) must be greater than 4.0 10^9/L and platelet count greater than 150 10^9/L
to receive drug.
Week 1, 2, 4, 5, 7 and 8: BCG instillation: 50 mg wet weight (10•2±9•0x108 colony-forming
units) BCG Connaught substrain. Lyophilised (ie, freeze-dried) BCG are suspended in 50 ml
bacteriostatic-free 0.9% Sodium Chloride (NaCl) solution. After bladder draining, the
suspension is infused intravesically through a 14 Fr Foley catheter and retained in the
bladder for 60-90 min; bladder emptying is followed by catheter removal.
Week 3, 6 and 9: A Foley catheter is inserted and the bladder is carefully drained. 40 mg
MMC dissolved in 100 ml NaCl 0.9% solution are instilled intravesically through the
electrode catheter by gravity and retained in the bladder for 30 min, while 23 mA for 30 min
pulsed electric current is given externally. Two dispersive cathode electrodes are placed on
lower abdominal skin after degreasing with alcohol. The bladder is then emptied and the
catheter removed. Patients are assigned one course of treatment per week for 6 weeks with
sequential BCG and EMDA/MMC. Two BCG instillations and one EMDA/MMC instillation constitute
one cycle for a total of two cycles.
A CBC and basic metabolic panel (BMP) will be performed weekly and at the beginning of each
cycle. Prior to dosing with mitomycin C at week 3, a CBC will be performed and also at weeks
4 and 5 if the CBC has changed. A UA will be performed prior to each intravesicular
instillation.
Maintenance treatment of eMMC will be given at month 3, 4, 6, 7, 9 and 10 (after last dose
of BCG of the initial treatment). Maintenance of BCG will be given around month 5, 8, and
11. CBC, BMP, UA, and a history/physical (H&P) will be performed before each EMDA/MMC
procedure. UA and a H&P will be performed before each BCG.

Inclusion Criteria:
- After a restaging TURBT patients with histologically proven primary high grade
(grade3) and/or pT1 transitional cell carcinoma of the bladder, with or without pTis
and pTis alone are regarded as being at high risk for tumour recurrence and
progression.
- Patients may enroll in this study if they are thought to have no residual disease
after TURBT.
- Age 18 years or over
- Adequate bone-marrow reserve- ECOG performance status between 0 and 2
- Patients who are known PPD positive will be screened for active tuberculosis prior to
starting treatment with BCG.
Exclusion Criteria:
- known allergy to BCG or MMC
- prior systemic infection with BCG
- prior or concomitant urothelial tumours of the upper urinary tract or urethra
- previous muscle-invasive (ie, stage T2 or higher) transitional-cell carcinoma of the
bladder
- bladder capacity of less than 200 ml
- untreated urinary-tract infection
- severe systemic infection (ie, sepsis)
- known HIV-positivity; therapy with immunosuppressive agents
- urethral strictures that would prevent endoscopic procedures and repeated
catheterisation
- upper urinary tract disease (eg, vesicoureteral reflux or urinary-tract stones) that
would make multiple transurethral procedures a risk
- previous radiotherapy to the pelvis
- other concurrent chemotherapy
- treatment with radiotherapy-response or biological-response modifiers
- history of tuberculosis;
- other malignant diseases within 5 years of trial registration (except for adequately
treated basal-cell or squamous cell skin cancer, in situ cervical cancer and any
other cancer from which patients has been disease-free for 3 years);
- pregnancy or nursing
- psychological, familial, sociological, or geographical factors that would preclude
study participation.
- Patients with implantable or wearable electrical devices will be excluded from this
study.
- Patients with active tuberculosis
