What was measured

The GP instrument is a single assessment of overall pain and participants were assessed in global pain according to the following response categories: 1= no pain (anymore), 2 = less pain, 3 = no change and 4 = more pain. Low pain scores are considered a better outcome than a high pain score.

Analysis population: FAS with available data was analyzed.

Groups in this outcome

CAPOX+ Zolbetuximab

Participants received an intravenous (IV) infusion (as a minimum of 2-hour infusion) of zolbetuximab at a loading dose of 800 milligrams per square meter (mg/m\^2) on cycle 1 day 1 (C1D1) followed by subsequent doses of 600 mg/m\^2 every 3 weeks starting from C2D1 until participant met study treatment discontinuation criteria. Participants also received up to 8 treatments of capecitabine and oxaliplatin (CAPOX) treatment. Oxaliplatin was administered 130 mg/m\^2 IV on day 1 of each cycle over 2 hours for a maximum of 8 treatments; Capecitabine was administered orally at 1000 mg/m\^2 twice daily (bid) on days 1 through 14 of each cycle until the participant met study treatment discontinuation criteria. After a maximum of 8 treatments of oxaliplatin, participants may have continued to receive capecitabine taken twice daily on days 1 through 14 of each cycle at the investigator's discretion until the participant met study treatment discontinuation criteria. Each cycle was approximately 21

CAPOX+ Placebo

Participants received an IV infusion (as a minimum of 2-hour infusion) of placebo matched to zolbetuximab on C1D1 followed by subsequent doses every 3 weeks starting from C2D1 until participant met study treatment discontinuation criteria. Participants also received up to 8 treatments of CAPOX. Oxaliplatin was administered 130 mg/m\^2 IV on day 1 of each cycle over 2 hours for a maximum of 8 treatments; Capecitabine was administered orally at 1000 mg/m\^2 bid on days 1 through 14 of each cycle until the participant met study treatment discontinuation criteria. After a maximum of 8 treatments of oxaliplatin, participants may have continued to receive capecitabine taken twice daily on days 1 through 14 of each cycle at the investigator's discretion until the participant met study treatment discontinuation criteria. Each cycle was approximately 21 days.
