A Study for Treatment of Superficial Bladder Cancer Using OGX-427

Status Recruiting

Clinical Trial Summary

This is a single centre, open label, phase I dose escalation trial using a modified accelerated titration design. Patients with superficial bladder tumour (Ta or T1) or CIS and candidates for transurethral resection or muscle invasive disease (>T2) and candidates for radical cystectomy will be enrolled.

OGX-427 will be given neoadjuvantly over 8 days, followed by a transurethral resection (for superficial disease) or radical cystectomy (for muscle invasive disease).

Baseline Hsp27 levels will be determined from pre-treatment cytological samples from bladder washings and tumour biopsies performed prior to therapy.

Post-treatment PK and PD data will be determined from TUR (for Ta, T1 tumours) or radical cystectomy (for T2 tumours) specimens. A recommended phase II dose will be determined from the toxicity, tissue pK, and percentage of Hsp27 knockdown. Effects of treatment on Hsp27 client protein levels and apoptotic index will also be evaluated.

Evaluation during protocol treatment will take place to assess toxicity. Assessments will occur on various visits as per Evaluation Schedule. Adverse event evaluation based on NCI CTCAEv3.0. For quality of life assessment during treatment, the EORTC QLC-BLS24 will be used before first treatment (day 1) and prior to surgery (TURBT or radical cystectomy). The Day 1 QOL assessment will serve as baseline.

After removal from protocol treatment, all subjects will be followed for toxicity related to study drug for 30 days.

After the study, subjects will be followed according to standard of care. Follow-up for tumour recurrence or superficial tumours will be assessed every three months by cystoscopic examination for two years, then every six months for the next two years, and then yearly thereafter.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
