What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The primary safety endpoint will be the determination of the maximum tolerated dose (MTD) / study maximum dose (SMD) based on the occurrence of dose-limiting toxicities (DLTs) during the 28-day DLT assessment period.

    Measured: Day28

Secondary outcomes (5)
  1. TB-403 total exposure (AUC∞) after single ascending dose

    Measured: Day 1, day 4, day 8, day 15, day 29, day 60, day 90, day 165 and day 195.

  2. TB-403 Dose/CL after single ascending dose

    Measured: Day 1, day 4, day 8, day 15, day 29, day 60, day 90, day 165 and day 195.

  3. TB-403 Volume of the central compartment (Vc) after single ascending dose

    Measured: Day 1, day 4, day 8, day 15, day 29, day 60, day 90, day 165 and day 195.

  4. TB-403 Volume of distribution at steady-state (Vss) after single ascending dose

    Measured: Day 1, day 4, day 8, day 15, day 29, day 60, day 90, day 165 and day 195.

  5. TB-403 terminal half-life (t½,z) after single ascending dose

    Measured: Day 1, day 4, day 8, day 15, day 29, day 60, day 90, day 165 and day 195.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing TB-403 20mg/kg, TB-403 50mg/kg and TB-403 100mg/kg in people with Relapsed or Refractory Medulloblastoma (MB), Neuroblastoma (NB), Ewing Sarcoma (ES) and Alveolar Rhabdomyosarcoma (ARMS), run by Oncurious NV at 10 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 20 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 13 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The primary safety endpoint will be the determination of the maximum tolerated dose (MTD) / study maximum dose (SMD) based on the occurrence of dose-limiting toxicities (DLTs) during the 28-day DLT assessment period. (time frame: Day28). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Jan 2021.
