About this study

Official title: A Phase 1, Open-label, Dose Escalation Study of MGA271 in Pediatric Patients With B7-H3-Expressing Relapsed or Refractory Solid Tumors

This study is a Phase 1, open-label, dose escalation and cohort expansion trial designed to characterize the safety, tolerability, PK, PD, immunogenicity and preliminary antitumor activity of enoblituzumab administered IV on a weekly schedule for up to 96 doses (approximately 2 years) in children and young adults with B7-H3-expressing relapsed or refractory malignant solid tumors.

Read the detailed description

This study is a Phase 1, open-label, dose escalation and cohort expansion trial designed to characterize the safety, tolerability, PK, PD, immunogenicity and preliminary antitumor activity of enoblituzumab administered IV on a weekly schedule for up to 96 doses (approximately 2 years) in children and young adults with B7-H3-expressing relapsed or refractory malignant solid tumors.

The study consists of a Dose Escalation Phase to determine the MTD (or MAD) of enoblituzumab followed by a Cohort Expansion Phase to further define the safety and initial antitumor activity of enoblituzumab. In the cohort expansion phase, 5 cohorts of 10 patients each will be enrolled to further evaluate the safety and potential efficacy of enoblituzumab administered at the MTD/MAD in patients with:1) neuroblastoma - measurable disease, 2) neuroblastoma - non-measurable disease, 3) rhabdomyosarcoma, 4) osteosarcoma, and 5) Ewing's sarcoma, Wilms' tumor, desmoplastic small round cell tumors, or malignant solid tumors of any other histology that test positive for B7-H3.

All tumor evaluations will be carried out by both Response Evaluation Criteria in Solid Tumors (RECIST) and immune-related response criteria (irRC). Disease assessment in patients with neuroblastoma will use neuroblastoma overall response criteria.

What is being measured

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

  1. Safety and tolerability of enoblituzumab.

    Adverse events, SAEs, incidence of treatment-emergent AE

    Measured: Time of first dose through end of treatment (up to 2 years)

Secondary outcomes (3)
  1. Peak plasma concentration

    PK of enoblituzumab

    Measured: Time of first dose through end of treatment (up to 96 weeks)

  2. Number of participants that develop anti-drug antibodies

    Proportion of patients who develop anti-MGA271 antibodies, immunogenicity

    Measured: Time of first dose through end of treatment (up to 96 weeks)

  3. Antitumor activity of enoblituzumab

    Anti-tumor activity of enoblituzumab using conventional RECIST 1.1 and immune related RECIST criteria

    Measured: Time of first dose through end of treatment (up to 96 weeks)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Enoblituzumab in people with Neuroblastoma and Rhabdomyosarcoma, run by MacroGenics at 6 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 0 inclusion and 14 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 8 Feb 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 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?

Safety and tolerability of enoblituzumab. (time frame: Time of first dose through end of treatment (up to 2 years)). 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 8 Feb 2022.
