Real-world Effectiveness and Safety of Trastuzumab Deruxtecan in Patients With Locally Advanced or Metastatic HER2-positive Gastric or Gastroesophageal Junction Adenocarcinoma in China: A Nation-wide, Multi-center, Prospective, Non-interventional Study

Trastuzumab deruxtecan's (T-DXd's) efficacy and safety has been confirmed in traditional clinical trials, there is a lack of real-world evidence, especially among Chinese patients. The objective of this study is to evaluate real-world effectiveness and safety profile of T-DXd by collecting real-world data treating in patients with locally advanced or metastatic HER2-positive gastric or gastroesophageal junction adenocarcinoma.

Detailed Description

The primary objective of this study is to evaluate the effectiveness of T-DXd in real-world setting (real-word time to treatment failure).

The secondary objectives of this study are to assess the safety profile of T-DXd (treatment related adverse events [TRAE] regardless of grade, and physician reported adverse events of special interest [AESI] regardless of grade, etc.) and to evaluate effectiveness of T-DXd (real-world time to next treatment). This is an non-interventional, observational study. No drug will be provided or administered as part of this protocol; however, participants on T-DXd will be enrolled in this study.

Sampling Method

Non-Probability Sample

Study Population

Eligible participants for this study include participants with HER2-positive local advanced or metastatic GC/GEJA.

Description

Participants must meet all the following inclusion criteria to be eligible for the study:

  1. Participants with pathologically diagnosed locally advanced unresectable or metastatic gastric cancer/gastroesophageal junction adenocarcinoma (GC/GEJA).
  2. ≥18 years of age at the time of starting the first dose of T-DXd and signing informed consent form (ICF), capable of providing informed consent.
  3. HER2-positive status (IHC 3+ or IHC 2+/ISH +).
  4. Received prior anti-cancer treatment regimens according to National Medical Products Administration indication or clinical judgement of physician.

Design Details

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
HER2-positive gastric/gastroesophageal junction adenocarcinoma
Patients who are diagnosed with locally advanced or metastatic HER2-positive gastric or gastroesophageal junction adenocarcinoma who made a decision (prior to enrolling in this study) to receive T-DXd treatment in a clinical practice setting.
Drug: Trastuzumab deruxtecan (T-DXd)
This is an non-interventional, observational study. No drug will be provided or administered as part of this protocol; however, participants on T-DXd (starting dose 6.4 mg/kg IV Q3W) will be enrolled in this study as part of clinical routine or the clinical judgement of physician.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Real-world Time to Treatment Failure (rwTTF)
Time Frame: T-DXd treatment initiation date (index date) to date of treatment discontinuation due to disease progression, physician decision, adverse events or death, whichever occurs first, up to approximately 2 years
rwTTF is defined as time from T-DXd treatment initiation date to the earliest date of treatment discontinuation due to disease progression, physician decision, adverse events or death.
T-DXd treatment initiation date (index date) to date of treatment discontinuation due to disease progression, physician decision, adverse events or death, whichever occurs first, up to approximately 2 years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Real-world Time to Next Treatment (rwTTNT)
Time Frame: T-DXd treatment initiation date (index date) to the date of receiving next line anti-cancer treatment or death, whichever occurs first, up to approximately 2 years
rwTTNT is defined as time from T-DXd treatment initiation date to the earliest date of receiving next line anti-cancer treatment, or death.
T-DXd treatment initiation date (index date) to the date of receiving next line anti-cancer treatment or death, whichever occurs first, up to approximately 2 years
Number of Participants Reporting Treatment Related Adverse Events (TRAE) and Physician-reported Adverse Event of Special Interest (AESI), Regardless of Grade
Time Frame: T-DXd treatment initiation date (index date) until end of study, or death, or withdrawal of consent, or loss to follow-up (LTFU), or study closure, whichever occurs first, up to approximately 2 years
A TRAE is defined as a harmful reaction, resulting from the normal usage and dosage to a medicinal product, which is unrelated to the purpose of medication. Physician-reported AESIs are defined as interstitial lung disease/pneumonitis and left ventricular ejection fraction decrease.
T-DXd treatment initiation date (index date) until end of study, or death, or withdrawal of consent, or loss to follow-up (LTFU), or study closure, whichever occurs first, up to approximately 2 years
