Secondary Objectives:

  • To assess safety and tolerability
  • To assess durability of response (DOR)
  • To assess progression-free survival (PFS)
  • To assess the disease control rate (DCR)
  • To assess the pharmacokinetics (PK)

Tusamitamab ravtansine+RamucirumabExperimentalParticipants received ramucirumab 8 milligram/kilogram (mg/kg) via intravenous (IV) infusion followed by tusamitamab ravtansine loading dose at 170 mg/meter square (m^2) via IV infusion on Cycle 1 Day 1 (each cycle was 2 weeks); and then ramucirumab 8 mg/kg via IV infusion followed by tusamitamab ravtansine 100 mg/m^2 via IV infusion at Cycle 2 and every 2 weeks (Q2W) in all subsequent cycles until disease progression, unacceptable adverse event (AE), death, initiation of a new anticancer therapy, or the participant's or investigator's decision to stop the treatment.
Receives: Drug: Ramucirumab (CYRAMZA®); Drug: Tusamitamab ravtansine (SAR408701)

What is being measured

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

  1. Part 1: Number of Participants With Study-Drug Related Dose Limiting Toxicities (DLTs)

    The following AEs occurred during the first 2 cycles of treatment, unless due to disease progression or to a cause obviously unrelated to study drug, were considered DLTs:

    • Grade 4 neutropenia for 7 or more consecutive days.
    • Grade 3 to 4 neutropenia complicated by fever (temperature >=38.5 degree Celsius on more than 1 occasion) or microbiologically or radiographically documented infection.
    • Grade >=3 thrombocytopenia associated with clinically significant bleeding requiring clinical intervention.
    • Grade 4 non-hematologic AE.
    • Grade >=3 keratopathy. In addition, any other AE that the Investigators and sponsor deemed to be dose limiting, regardless of its grade, was also considered as DLT.

    Measured: From Cycle 1 Day 1 to Cycle 2 Day 14; approximately 28 days

  2. Objective Response Rate (ORR)

    The ORR was defined as percentage of participants with confirmed complete response (CR) or partial response (PR) as best overall response (BOR) determined per Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1. The CR was defined as disappearance of all target lesions. The PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.

    Measured: Tumor assessments performed at Baseline (Day 1), then every 6 weeks (±7 days) thereafter, approximately 88.1 weeks

Secondary outcomes (7)
  1. Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Treatment Emergent Serious Adverse Events (TESAEs)

    An AE was any untoward medical occurrence in a participant or clinical study participant, temporally associated with the use of study drug, whether or not considered related to the study drug. A SAE was defined as any untoward medical occurrence that, at any dose: resulted in death or was life-threatening or required inpatient hospitalization or prolongation of existing hospitalization or resulted in persistent disability/incapacity or congenital anomaly/birth defect. TEAE was defined as AEs that developed, worsened, or became serious during the treatment-emergent period.

    Measured: From the first study drug administration (Day 1) up to 30 days after the last study drug administration, approximately 120 weeks

  2. Duration of Response (DOR)

    The DOR was defined as the time from first documented evidence of CR or PR until progressive disease (PD) determined per RECIST v1.1 or death from any cause, whichever occured first. The PD was defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study.

    Measured: Tumor assessments performed at Baseline (Day 1), then every 6 weeks (±7 days) thereafter, approximately 88.1 weeks

  3. Progression-free Survival (PFS)

    The PFS was defined as the time from the first study drug administration to the date of the first documented disease progression or death due to any cause, whichever came first as per RECIST v1.1.

    Measured: Tumor assessments performed at Baseline (Day 1), then every 6 weeks (±7 days) thereafter, approximately 88.1 weeks

  4. Disease Control Rate (DCR)

    The DCR was defined as the percentage of participants who achieved confirmed CR, confirmed PR or stable disease (SD) as per RECIST v1.1. The SD was defined as neither sufficient shrinkage from the baseline study to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study.

    Measured: Tumor assessments performed at Baseline (Day 1), then every 6 weeks (±7 days) thereafter, approximately 88.1 weeks

  5. Individual Observed Predose Concentrations (Ctrough) of Tusamitamab Ravtansine

    Blood samples were collected for the measurement of Ctrough of tusamitamab ravtansine.

    Measured: Pre-infusion on Cycle 2 Day 1

  6. Individual Observed Predose Concentrations (Ctrough) of Ramucirumab

    Blood samples were collected for the measurement of Ctrough of concentrations of ramucirumab.

    Measured: Pre-infusion on Cycle 2 Day 1

  7. Number of Participants With Antitherapeutic Antibodies (ATAs) Against Tusamitamab Ravtansine

    Blood samples were collected to assess the presence of ATA against tusamitamab ravtansine in plasma from all participants. ATA incidence was defined as the number of participants found to have seroconverted (treatment-induced ATAs) or boosted their pre-existing ATA response (treatment-boosted ATAs) at any time after first study drug administration.

    Measured: Upto 92.1 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Ramucirumab (CYRAMZA®) and Tusamitamab ravtansine (SAR408701) in people with Adenocarcinoma Gastric and Gastrooesophageal Cancer, run by Sanofi at 21 sites in 6 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 8 inclusion and 21 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 22 Aug 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 21 sites in Japan, South Korea, Spain, Turkey (Türkiye), Belgium and 1 more country. 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?

Yes. Results are posted in the registry (first posted 5 Dec 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Part 1: Number of Participants With Study-Drug Related Dose Limiting Toxicities (DLTs) (time frame: From Cycle 1 Day 1 to Cycle 2 Day 14; approximately 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?
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 22 Aug 2025.
