About this study

Official title: Widening Treatment Options Among Adult Patients With HER2-overexpressing or Mutant Solid Cancers.

Alterations in the HER2 gene are involved in the development of cancer. These abnormalities are found at highly variable rates (from approximately 2% to 60%) in cancers of the lung, breast, stomach, bile ducts, salivary glands, colon, endometrium, uterus, bladder, bones, blood, etc. Zanidatamab is an anti-cancer drug that acts on cells with alterations in the HER2 gene. It is used in Europe to treat people with bile duct cancer.

However, in various clinical trials, zanidatamab has shown promising activity in a few patients with different cancers that have a HER2 gene alteration. This treatment could therefore be effective in several types of cancer once this gene alteration is detected.

The primary objective is to evaluate the efficacy of zanidatamab in patients with cancer in one of the following locations: endometrium, colorectal, head and neck, sarcoma or lung cancer. Efficacy will be measured by the number of patients in whom a reduction in tumour size was observed.

All patients included in the study will receive zanidatamab by intravenous infusion every 3 weeks. Treatment will continue as long as there is a benefit (stabilisation or regression of the disease). During treatment, participants will visit the hospital regularly for medical consultations to:

  • assess and treat potential adverse effects of zanidatamab. A dose reduction may be applied to improve tolerance.
  • monitor disease progression using scans and/or MRI, performed every 6 weeks for the first 18 months of treatment and then every 12 weeks.

After treatment is stopped (due to intolerance or disease progression), patients will be monitored according to hospital practices until the end of the trial, i.e. for 1 to 4 years, depending on when they were included in the clinical trial.

What is being measured

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

  1. Confirmed Objective Response Rate (ORR) by investigator

    Confirmed Objective Response Rate (ORR) for each cohort, based on best overall response, defined as the percentage of patients with a complete response (CR) or partial response (PR) during treatment or follow-up, assessed according to RECIST1.1, by investigator assessment and confirmed by a follow-up scan at ≥ 4 weeks from first response assessment.

    Measured: From Baseline to disease progression (up to 28 months)

Secondary outcomes (6)
  1. Confirmed ORR by the BICR

    Confirmed ORR for each cohort, based on best overall response as adjudicated by the BICR, defined as the percentage of patients with a CR or PR during treatment or follow-up, assessed according to RECIST1.1 and confirmed by a follow-up scan at ≥ 4 weeks from first response assessment

    Measured: From baseline to the progression (up to 28 months)

  2. Duration of Response (DoR)

    Duration of Response (DoR) for each cohort will be evaluated in patients with either a CR or PR. DoR is defined as the time from the first assessment of a confirmed CR or PR until the date of the first occurrence of progressive disease (PD) according to RECIST1.1 or death from any cause (if death occurs within predefined period), whichever occurs first. At the time of analysis, a patient alive and without disease progression will be censored at the date of the last valid tumor assessment. DoR will be provided as assessed by investigators and as adjudicated by the BICR.

    Measured: From baseline to the progression (up to 28 months)

  3. Progression Free Survival (PFS)

    Progression Free Survival (PFS) for each cohort is defined as the time from study registration until disease progression (per RECIST1.1) or death from any cause, whichever occurs first. At the time of analysis, a patient alive and without disease progression will be censored at the date of the last valid tumor assessment. PFS will be provided as assessed by investigators and as adjudicated by the BICR.

    Measured: From baseline to disease progression or death (up to 28 months)

  4. Clinical Benefit Rate (CBR)

    Clinical Benefit Rate (CBR) for each cohort is defined as the percentage of patients with a CR or PR or stable disease (SD) for more than 16 weeks from inclusion assessed according to RECIST1.1. CBR will be provided as assessed by investigators and as adjudicated by the BICR.

    Measured: From baseline to the progression (up to 28 months)

  5. Overall Survival (OS)

    Overall Survival (OS) for each cohort is defined as the time from study registration until death from any cause. Patients who are alive at last follow-up will be censored at this date.

    Measured: From baseline to death (up to 52 months)

  6. Incidence of treatment-Emergent Adverse Events [Safety and Tolerability of zanidatamab]

    The safety will be evaluated according to the incidence of adverse events (AEs) graded by NCI-CTCAE v5.0, per cohort and overall.

    Measured: From baseline to the end of treatment (up to 28 months)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Zanidatamab in people with Non-Small Cell Lung Cancer and Sarcoma, run by UNICANCER at 4 sites in France.

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 19 inclusion and 18 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: looking for participants now, as of the sponsor's last update on 19 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in France. 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 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Céline MAHIER AIT OUKHATAR (+33 (0)6 17 51 34 29, c-mahier@unicancer.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Confirmed Objective Response Rate (ORR) by investigator (time frame: From Baseline to disease progression (up to 28 months)). 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 19 Dec 2025.
