Oesophageal Squamous Cell Carcinoma
Conditions
Brief summary
The purpose of this trial is to assess if ifinatamab deruxtecan (I-DXd) can treat esophageal squamous cell carcinoma (ESCC). I-DXd is an antibody-drug conjugate (ADC). An ADC attaches to a protein on cancer cells and delivers treatment to destroy those cells. The goal of this trial is to learn how many participants who receive I-DXd have the cancer respond, which means the cancer gets smaller or goes away.

Inclusion criteria
* Has a histologically or cytologically confirmed diagnosis of unresectable locally advanced or metastatic esophageal squamous cell carcinoma (ESCC) * Has disease progression after 1 or 2 prior lines of systemic therapy for unresectable locally advanced or metastatic ESCC * Has measurable disease * If infected with human immunodeficiency virus (HIV), has well-controlled HIV on antiretroviral therapy * Has adequate organ function
Exclusion criteria
* Has histologically or cytologically confirmed adenocarcinoma or adenosquamous carcinoma subtype * Has uncontrollable pleural effusion, pericardial effusion, or ascites requiring frequent drainage or medical intervention * Has clinically significant corneal disease * Has any of the following within 6 months before screening: cerebrovascular accident, transient ischemic attack, other arterial thromboembolic event * If infected with HIV, has a history of Kaposi's sarcoma and/or Multicentric Castleman's Disease * Has uncontrolled or significant cardiovascular disease * Has a known additional malignancy that is progressing or has required active treatment within the past 3 years * Has known active central nervous system metastases and/or carcinomatous meningitis * Has a history of (noninfectious) pneumonitis/interstitial lung disease irrespective of requiring steroids or has any current pneumonitis/interstitial lung disease or has suspected pneumonitis/interstitial lung disease * Has active infection requiring systemic therapy other than those permitted. * Has clinically severe pulmonary compromise resulting from intercurrent pulmonary illnesses, including, but not limited to, any underlying pulmonary disorder (ie, pulmonary emboli within 3 months of the study enrollment, severe asthma, severe chronic obstructive pulmonary disease, restrictive lung disease, pleural effusion, etc), and potential pulmonary involvement caused by any autoimmune, connective tissue, or inflammatory disorders (eg, rheumatoid arthritis, Sjögren's syndrome, sarcoidosis, etc), prior pneumonectomy, or requirement for supplemental oxygen
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Objective Response Rate (ORR) | Up to approximately 15 months | ORR is defined as the percentage of participants with Complete Response (CR: disappearance of all target lesions) or Partial Response (PR: at least a 30% decrease in the sum of diameters of target lesions) per Response Evaluation Criteria In Solid Tumors Version 1.1 (RECIST 1.1). The percentage of participants who experience CR or PR as assessed by Blinded Independent Central Review (BICR) will be presented. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Duration of Response (DOR) | Up to approximately 18 months | For participants who demonstrate a confirmed CR (disappearance of all target lesions) or (at least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1, DOR is defined as the time from first documented evidence of CR or PR until progressive disease (PD) or death. Per RECIST 1.1, PD is defined as at least a 20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 millimeters (mm). The appearance of one or more new lesions is also considered PD. DOR as assessed by BICR will be presented. |
| Progression-Free Survival (PFS) | Up to approximately 18 months | PFS is defined as the time from randomization to the first documented progressive disease (PD) or death due to any cause, whichever occurs first as assessed by RECIST 1.1. PD is defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. The appearance of one or more new lesions is also considered PD. PFS as assessed by BICR will be presented. |
| Overall Survival (OS) | Up to approximately 27 months | OS is defined as time from randomization to death due to any cause. |
| Number of Participants Who Experience an Adverse Events (AEs) | Up to approximately 18 months | An AE is defined as any unfavorable and unintended sign, symptom, disease, or worsening of preexisting condition temporally associated with study treatment and irrespective of causality to study treatment. |
| Number of Participants Who Discontinue Study Treatment Due to an AE | Up to approximately 18 months | An AE is defined as any unfavorable and unintended sign, symptom, disease, or worsening of preexisting condition temporally associated with study treatment and irrespective of causality to study treatment. |
