NCT07758881

Brief Summary

The goal of this clinical trial is to evaluate the safety and performance of the Eight Medical Hyperthermia System IV 1.0 when used to deliver recirculating hyperthermic intravesical chemotherapy (HIVEC) with mitomycin C (MMC) in adult patients with non-muscle invasive bladder cancer (NMIBC). The main questions it aims to answer are:

  • Is the Eight Medical Hyperthermia System IV 1.0 safe when used to deliver HIVEC with MMC in adult patients with NMIBC?
  • Does the Eight Medical Hyperthermia System IV 1.0 perform as intended by successfully delivering HIVEC with MMC? Participants will:
  • Receive HIVEC treatment with MMC using the Eight Medical Hyperthermia System IV 1.0 according to the study treatment schedule.
  • Attend scheduled study visits for safety assessments, clinical evaluations, and follow-up.

Outcome Measures

Primary Outcomes (1)

  • To assess the safety profile of the Eight Medical Hyperthermia System IV 1.0, used to deliver recirculating hyperthermic intravesical chemotherapy (HIVEC) with mitomycin C (MMC) in patients diagnosed with NMIBC.

    Safety will be assessed by documenting all peri- and post-treatment (serious) adverse events, from the treatment onwards up to 30 days post-treatment (defined as the date of last intravesical instillation). This will include assessment of the frequency, severity, and nature of the (serious) adverse events and the treatment received.

    Visit 1 (week 1), visit 2 (week 2), visit 3 (week 3), visit 4 (week 4), visit 5 (week 5), visit 6 (week 6), visit 7 (week 10), visit 8 (week 14), visit 9 (week 18), visit 10 (week 22), visit 11 (week 26), visit 12 (week 30), study exit visit (week 34)

Secondary Outcomes (16)

  • To evaluate the performance of the Eight Medical Hyperthermia System IV 1.0, used to deliver recirculating HIVEC with MMC in patients diagnosed with NMIBC.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • ≥ 18 years of age at study entry.
  • Histologically confirmed intermediate-risk or high-risk NMIBC, as defined by the 2025 version of the European Association of Urology (EAU) guidelines.
  • ECOG Performance Status of 0-2.
  • Candidate for HIVEC according to clinical judgment and the device and medicinal product labeling/contra-indications.
  • The participant and investigator signed and dated the informed consent form prior to the treatment.
  • Available, willing, and with sufficient cognitive awareness to comply with the protocol or proposed follow-up visits.

You may not qualify if:

  • A small bladder capacity (\<150 ml), based on site standard assessment and investigator judgment.
  • Active or uncontrolled Urinary Tract Infection (UTI), defined as clinical signs/symptoms and/or microbiological evidence requiring treatment per investigator judgment.
  • Positive urine culture prior to the instillation that indicates active infection not adequately treated or controlled.
  • Inability to hold urine for more than 1 hour.
  • Gross hematuria that precludes safe catheterization or intravesical therapy.
  • Severe bladder wall damage or other bladder pathology that increases the risk of complications or prevents safe instillation.
  • Non-controlled bladder overactivity that prevents completion of the planned dwell time.
  • Urethral strictures or other anatomical/functional conditions that complicate or prevent safe catheterization.
  • Known vesico-ureteral reflux that increases risk with intravesical chemotherapy.
  • Inability to remain in the supine position for at least 60 minutes.
  • Known allergy or hypersensitivity to Mitomycin C.
  • Current or history of clinically significant hematologic disorder that may increase risk of bleeding, infection, or systemic toxicity, or confound safety assessment.
  • Autoimmune disease, systemic inflammatory disease or other medical conditions that will likely affect study outcomes or participant safety.
  • Tumor tissue in the bladder containing \<50% urothelial cancer.
  • (A history of) muscle-invasive bladder cancer (≥ T2) or metastatic disease.
  • +6 more criteria
