Brief Summary:

This study will test a drug called enfortumab vedotin in participants with a type of bladder cancer called non-muscle invasive bladder cancer (NMIBC).

This study will also evaluate what the side effects are and if the drug works to treat NMIBC. A side effect is anything a drug does to your body besides treating your disease.

In this study enfortumab vedotin will be put into the bladder using a catheter. A catheter is a thin tube that can be put into your bladder.


Condition or disease Intervention/treatment Phase
Urinary Bladder Neoplasms Carcinoma in Situ Carcinoma Transitional Cell Non-muscle Invasive Bladder Cancer NMIBC Drug: Enfortumab vedotin Phase 1

Detailed Description:

The study will be comprised of 2 parts. The first part (dose escalation) will find the highest dose of enfortumab vedotin that does not cause unacceptable side effects in participants. The second part (dose expansion) will use the dose found in the first part to test how well the drug works.

All participants will receive enfortumab vedotin. Treatment on the study will occur during the induction and maintenance phases, and participants will enter a follow-up period after completion of the maintenance phase.

Primary Outcome Measures :
  1. Incidence of adverse events (AEs) [ Time Frame: Approximately 1 year ]
    An AE is any untoward medical occurrence in a subject or clinical investigational subject administered a medicinal product and which does not necessarily have a causal relationship with this treatment.

  2. Incidence of laboratory abnormalities [ Time Frame: Approximately 1 year ]
    To be summarized using descriptive statistics.

  3. Incidence of dose limiting toxicities (DLTs) [ Time Frame: Approximately 7 weeks ]
    To be summarized using descriptive statistics.


Secondary Outcome Measures :
  1. Pharmacokinetics (PK) of enfortumab vedotin: Area under the concentration-time curve (AUC) [ Time Frame: Approximately 1 year ]
    AUC will be recorded from the PK blood samples collected.

  2. PK of enfortumab vedotin: Maximum concentration (Cmax) [ Time Frame: Approximately 1 year ]
    Cmax will be recorded from the PK blood samples collected.

  3. PK of enfortumab vedotin: Time to maximum concentration concentration (tmax) [ Time Frame: Approximately 1 year ]
    Tmax will be recorded from the PK blood samples collected.

  4. PK of enfortumab vedotin: Apparent terminal half-life (t1/2) [ Time Frame: Approximately 1 year ]
    T1/2 will be recorded from the PK blood samples collected.

  5. PK of enfortumab vedotin: Trough concentration (Ctrough) [ Time Frame: Approximately 1 year ]
    Ctrough will be recorded from the PK blood samples collected.

  6. Incidence of antitherapeutic antibodies (ATAs) to enfortumab vedotin [ Time Frame: Approximately 1 year ]
    Blood samples for ATA analysis will be collected.

  7. Complete response (CR) rate [ Time Frame: Up to 24 months ]
    CR rate is defined as the proportion of subjects achieving CR.

  8. Duration of CR [ Time Frame: Up to 5 years ]
    The time from first documented CR to the first evidence of recurrence, progression, or death due to any cause.

  9. Rate of cystectomy [ Time Frame: Up to 5 years ]
    The proportion of subjects who subsequently undergo cystectomy.

  10. Progression-free survival [ Time Frame: Up to 5 years ]
    The time from start of study treatment to the first evidence of progression or death due to any cause.

  11. Cystectomy-free survival [ Time Frame: Up to 5 years ]
    The time from start of study treatment to cystectomy or death due to any cause.
