Conditions

Claudin (CLDN)18.2-Positive, HER2-Negative, Locally Advanced Unresectable or Metastatic Gastric or Gastroesophageal Junction (GEJ) Adenocarcinoma

Brief summary

The primary endpoint is progression free survival (PFS), defined as the time from the date of randomization until the date of radiological progressive disease (PD) per Response Evaluation Criteria In Solid Tumors 1.1 (RECIST 1.1) by independent review committee (IRC) or death from any cause, whichever is earliest.

Detailed description

OS, defined as the time from the date of randomization until the date of death from any cause, "Time to confirmed deterioration (TTCD) using the PF, OG25-Pain and GHS/QoL scores as measured by EORTC QLQ-C30 and QLQ-OG25 plus STO22 Belching subscale. TTCD is defined as time to first confirmed deterioration, i.e., time from randomization to first clinically meaningful deterioration that is confirmed at the next scheduled visit.", ORR, defined as the proportion of subjects who have a best overall response of complete response (CR) or partial response (PR) as assessed by IRC per RECIST 1.1, DOR, defined as the time from the date of the first response (CR/PR) until the date of PD as assessed by IRC per RECIST 1.1 or date of death from any cause, whichever is earliest, Safety and tolerability, as measured by AEs, laboratory test results, vital signs, ECGs and ECOG performance status, HRQoL using the additional parameters as measured by EORTC QLQC30, QLQ-OG25 plus STO22 Belching subscale, GP and EQ5D-5L questionnaires, Pharmacokinetics of zolbetuximab, Ctrough, Immunogenicity of zolbetuximab as measured by the frequency of antidrug-antibody (ADA) positive subject
