An International Randomized Study to Compare SPIES Versus WLI

July 27, 2021 updated by: Clinical Research Office of the Endourological Society

The SPIES Non-Muscle-Invasive Bladder Cancer Study - A Multicenter Randomized Controlled Study; A Multicenter International Randomized Controlled Study to Compare the Outcome Using the Storz Professional Image Enhancement System (SPIES) Versus White Light Imaging (WLI) During TURB of Non-Muscle-Invasive Bladder Cancer (NMIBC).

This study is a multicenter randomized controlled trial in which the efficacy between SPIES assisted and WLI assisted TURB are compared. Subjects in the experimental arm (Arm A) will undergo SPIES assisted TURB, whereas subjects in the control arm (Arm B) will receive treatment with WLI assisted TURB only. Baseline characteristics will be recorded, as well as short and long-term follow up.

Detailed Description

This study is a multicenter randomized controlled trial in which the recurrence rates of cancer between SPIES assisted and WLI assisted TURB are compared. Randomization is stratified by tumor multiplicity (single or multiple), tumor status (primary or recurrent) and macroscopic findings (papillary or flat, where CIS is scored as flat lesion). Patients randomized into the experimental arm (Arm A) will undergo SPIES and WLI assisted TURB, whereas the patients in the control arm (Arm B) will undergo WLI only assisted TURB. WLI is chosen as control, since it is considered the gold standard for detecting bladder tumors. Short and long term follow up will be recorded in order to evaluate the health gains for patients over a longer period. Perioperative (30 days) complications will be compared between the two treatment arms to evaluate the safety of SPIES.

Eligibility Criteria

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Has signed informed consent
  • Is scheduled for treatment of a primary or recurrent NMIBC
  • Is aged 18 years or older
  • Has or has had no tumors in the upper urinary tract
  • Has had no previous irradiation of the pelvis

Exclusion Criteria:

  • Gross haematuria at the time of TURB (i.e. heavy bladder bleeding resulting in marked amounts of blood in the urine which may interfere with cystoscopy)
  • Participation in other clinical studies with investigational drugs either concurrently or within the last 30 days
  • Pregnancy or breast-feeding (all women of child-bearing potential must document a negative serum or urine pregnancy test at screening and are suggested to use the contraceptive pill or an intrauterine device (IUD) during the treatments and for at least one months thereafter)
  • Conditions associated with a risk of poor protocol compliance
  • Has had instillation therapy in the six months prior to the screening visit
