About this study

Official title: Metro-PD1: a Phase I/II Trial Evaluating Anti-PD1 (Nivolumab) in Combination With Metronomic Chemotherapy in Children and Teenagers With Refractory / Relapsing Solid Tumors

The study is a two-stage trial:

  1. First stage (closed - 16 patients recruited in France): Phase I feasibility trial to evaluate the safety of the combination of Nivolumab + metronomic chemotherapy considering three possible metronomic chemotherapy regimens
  2. Second stage (opened - 86 patients expected in France and Belgium): Phase II randomized controlled balanced 1:1 open-label trial comparing the efficacy of the metronomic chemotherapy regimen selected at the end of the previous stage (arm C: cyclophosphamide, capecitabine, vinblastine), with or without nivolumab.
  3. "Trans-MetroPD1" ancillary sub-study is partially implemented since April 2022, and proposed to patients participating to second stage
Read the detailed description
  1. First stage (closed):
  • Arm A: Nivolumab + Cyclophosphamide-Vinblastine
  • Arm B: Nivolumab + Capecitabin
  • Arm C: Nivolumab + Cyclophosphamide-Vinblastine + Capecitabin Arm A and Arm B have been allocated sequentially (A/B/A/B/A/B). Arm C has been opened, since arm A and Arm B were deemed safe. In each arm, the second patient was not recruited before the first patient has been observed for a 28-day duration.
  1. Second stage (opened): Following the analysis of safety data from first stage, and according to IDMC's recommendations on December 2020, the metronomic chemotherapy selected for second stage was arm C: cyclophosphamide, capecitabine, vinblastine Randomization will be balanced 1:1, controlling for:
  • histological type: embryonal brain tumor, ependymoma, low-grade glioma, rhabdomyosarcoma, neuroblastoma, Ewing sarcoma, and other solid tumors after approval from coordinators,
  • and treating center, using a dynamic allocation of treatment (minimization program) with a random factor set at 0.8.
  1. Trans-MetroPD1 is divided into 3 axes:
  • to evaluate the health-related quality of life
  • to measure the kinectis of progastrin/hPG80, a biomarker over-expressed in a wide range of cancers
  • to determine the distribution of immune cells within blood tissue
Being tested
Vinblastine, Cyclophosphamide, Capecitabine, Nivolumab

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Vinblastine, Cyclophosphamide and Capecitabine in people with Childhood Solid Tumor, run by Centre Oscar Lambret at 11 sites in 2 countries.

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 37 inclusion and 31 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: stopped early, as of the sponsor's last update on 17 Sep 2026. 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 France, Belgium. 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 combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 was stopped early (reason given: Analysis conducted on spring 2025, according to the provisional schedule: the results were sufficient to conclude about all endpoints, and the sponsor defined a new end of trial on 27 Dec 2025 (modification approved on CTIS on May 26, 2026).). Results are not available in the source record.

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?

Dose Limiting Toxicities according to the NCI-CTCAE V5 (time frame: Over the first chemotherapy cycle (28 days)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03585465.

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 17 Sep 2026.
