How this study is set up

The points below are drawn from the public registry record for this study. Each one cites the field or sentence it came from. A dash (—) means the record does not state something — not that it is missing or wrong. Many well-run studies, especially small ones, leave some of these blank.

  • Present: Registered before enrolment beganFirst posted 2024-08-23; recorded start 2024-09-16
  • Present: Has a defined primary outcomeA primary outcome measure is listed in the record
  • Present: The primary outcome states a time frameThe primary outcome measure records a time frame
  • Present: Participants are randomly assignedAllocation is recorded as randomised
  • Present: Has a comparison groupThe record lists a placebo or comparator arm, or more than one study arm
  • Not stated: Open label (no blinding)Masking is recorded as none (open label)
  • Not stated: An ethics committee is not stated in the registry recordThis registry's ingested record has no ethics-committee field
  • Not stated: Regulatory oversight (such as an IND or IDE) is not stated in the registry recordThis registry's ingested record has no regulatory-authorisation field
  • Not stated: A data monitoring committee is not stated in the registry recordThis registry's ingested record has no data-monitoring-committee fieldA data monitoring committee is not required for many smaller studies, and its absence here is not unusual.
  • Present: No cost to participants is mentioned in the recordChecked the summary, description and eligibility text; no cost-to-participant phrase found
  • Present: Sponsor has 3 other studies in this databaseCounted from the lead sponsor named in the record (CG Oncology, Inc.)
  • Not stated: No posted results from this sponsor are in this database yetBased on the sponsor’s studies in this database
  • The record lists 1 condition.
  • Lead sponsor type recorded as: industry.
  • Intervention regulatory context: investigational, within a phased regulatory pathway.

Trial stature

Three independent measures of this study, described from its registry record — not a recommendation about it. A rigorous study by investigators nobody has heard of is better evidence than a weak study led by a famous one. How these are scored.

Methodological rigourMODERATE

A moderately rigorous design for a phase 2 study, judged from its ClinicalTrials.gov record.

Investigator standingUNKNOWN

We have no verifiable track record for the investigator named on this trial. That is common for early-career investigators and for records held outside ClinicalTrials.gov — it is not a negative signal.

How this score is built
  • Investigator standing0/100

    No investigator recorded in the registry for this trial

These describe the registry record only, and today we hold ClinicalTrials.gov data. Absent fields lower a score, and absence often reflects registration practice rather than study quality. A high-stature trial is not necessarily safer or a better choice for you — enrolling in a large definitive trial can mean a higher chance of receiving placebo, while a small early-phase study may be the only route to a new therapy.

תקציר

This is a Phase 2, Multi-Arm, Multi-Cohort, Open-Label Study to Evaluate the Safety and Efficacy of Cretostimogene Grenadenorepvec in Participants with High-Risk Non-Muscle-Invasive Bladder Cancer.

In Cohort A, up to 125 participants will be enrolled with pathologically confirmed, high-risk high-grade non-muscle invasive bladder cancer (NMIBC) NMIBC (i.e., CIS with or without concomitant Ta or T1 disease OR HG Ta/T1 disease without CIS) which is naïve to Bacillus Calmette-Guerin (BCG) treatment. Participants with CIS with or without concomitant Ta/T1 NMIBC at baseline will be randomized 1:1 to receive cretostimogene via the current (Arm 1) or an alternative instillation procedure (Arm 2). Participants with papillary-only high-risk NMIBC (i.e., HG Ta/T1 without CIS) at baseline (Arm 3) will receive cretostimogene via the alternative instillation procedure. In Cohort B, up to 150 participants will be enrolled with pathologically confirmed, high-risk high-grade NMIBC (i.e., CIS with or without concomitant Ta or T1 disease OR HG Ta/T1 disease without CIS) which has previously been exposed to BCG treatment. Participants with CIS-containing pathology at baseline will be recruited into Arm 1 and participants with papillary-only pathology at baseline will be recruited into Arm 2. Both Cohort B Arms 1 and 2 will receive cretostimogene via the alternative instillation procedure. In Cohort CX, up to 50 participants will be enrolled with pathologically confirmed, high-risk high-grade NMIBC (i.e., CIS with or without concomitant Ta or T1 disease OR HG Ta/T1 disease without CIS) which has previously been exposed to or is unresponsive to BCG treatment. Participants will be randomized 1:1 to receive cretostimogene and gemcitabine either concurrently or sequentially. In all cohorts, study treatment will be administered as a weekly induction course for the first 6 weeks with a reinduction course administered to patients who have CIS and/or high-grade Ta disease at the 3-month evaluation. Following induction, if no high-grade disease is detected, maintenance treatment will begin. This consists of a cycle of three weekly treatments every three months during the first year, and every six months during the second year, with an optional extension to the third year following the same six-month schedule. Disease status will be assessed using urine cytology, complete bladder visualization (e.g., cystoscopy), upper tract assessment and directed resection/biopsy (if indicated) every 3 months for the first 2 years and then every 6 months for a further 2 years or until disease recurrence.
