About this study

Official title: A Phase I Trial of p28 (NSC745104), a Non-HDM2 Mediated Peptide Inhibitor of p53 Ubiquitination in Pediatric Patients With Recurrent or Progressive CNS Tumors

This phase I trial studies the side effects and best dose of azurin-derived cell-penetrating peptide p28 (p28) in treating patients with recurrent or progressive central nervous system tumors. Drugs used in chemotherapy, such as azurin-derived cell-penetrating peptide p28, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To establish whether the adult recommended phase II dose of 3x/week bolus infusions of p28is safe for pediatric patients with recurrent/refractory central nervous system (CNS) tumors.

II. To describe dose-limiting toxicities of 3x/week bolus infusions of p28 in pediatric patients with recurrent/refractory CNS tumors.

III. To evaluate and characterize the plasma pharmacokinetics of p28 in children with recurrent/ refractory CNS tumors.

SECONDARY OBJECTIVES:

  1. To describe in the context of a phase I trial any observed antitumor activity of p28.

II. To investigate levels of p53 in clinical tumor specimens of patients with pediatric gliomas and other pediatric CNS tumors treated with p28.

III. To document the type/site(s) of p53 mutation in tumor tissue specimens. IV. To evaluate and characterize the intratumoral pharmacokinetics of p28 in children with recurrent/ refractory CNS tumors, if available.

OUTLINE: This is a dose-escalation study.

Patients receive azurin-derived cell-penetrating peptide p28 intravenously (IV) over 15 minutes thrice weekly for 4 weeks. Treatment repeats every 6 weeks for up to 10 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for at least 30 days.

What is being measured

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

  1. Number of patients experiencing dose-limiting toxicities (DLT) defined as any adverse event or grade 3 or 4 toxicity graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0

    Measured: Up to 6 weeks

Secondary outcomes (3)
  1. Percentage of patients whose tumors are p53 positive (greater than or equal to 10% of tumor cells staining for p53)

    Will be estimated with its exact 95% confidence interval (CI).

    Measured: Up to 30 days post-treatment

  2. Type and frequency of p53 mutations present in the tumor specimens analyzed

    Will be summarized.

    Measured: Up to 30 days post-treatment

  3. Change in tumor size

    The proportion (and 95% CI) of subjects with an on-treatment tumor response or with clinical benefit will be provided.

    Measured: Baseline to up to 30 days post-treatment

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing azurin-derived cell-penetrating peptide p28 in people with Teratoid Tumor, Atypical and Choroid Plexus Neoplasms, run by Pediatric Brain Tumor Consortium at 11 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 25 inclusion and 6 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 7 Aug 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 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?

Number of patients experiencing dose-limiting toxicities (DLT) defined as any adverse event or grade 3 or 4 toxicity graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 (time frame: Up to 6 weeks). 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 7 Aug 2017.
