What was measured

EQ-5D-5L is a standardized instrument for use as a measure of health outcomes consisting of 6 items that cover 5 main domains (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression) and a general visual analog scale for health status.It was developed by the EuroQol Group for use as a generic, preference-based measure of health outcomes. Each dimension comprises 5 levels (no problems, slight problems, moderate problems, severe problems, extreme problems). A unique EQ-5D-5L health state is defined by combining 1 level from each of the 5 dimensions. This questionnaire also records the respondent's self-rated health status on a vertical graduated (0 = the worst health a participant can imagine to 100 = the best health a participant can imagine) visual analogue scale. Responses to the 5 items will also be converted to a weighted health state index (utility score) based on values derived from general population samples.

Analysis population: FAS with available data was analyzed.

Groups in this outcome

mFOLFOX6 + Zolbetuximab

Participants received an IV infusion (as a minimum of 2-hour infusion) of zolbetuximab at a loading dose of 800 mg/m\^2 on C1D1 followed by subsequent doses of 600 mg/m\^2 every 3 weeks starting from C1D22 until participant meets study treatment discontinuation criteria. Participants also received up to 12 treatments of 5-fluorouracil, folinic acid and oxaliplatin (mFOLFOX6) (or components of mFOLFOX6 if some components were discontinued due to toxicity) over 4 or more cycles in which mFOLFOX6 was administered on Days 1, 15 and 29 of each cycle (5-fluorouracil administered by IV bolus 400 mg/m\^2 over 5 to 15 minutes followed by 2400mg/m\^2 over 46-48 hours continuous IV infusion every 2 weeks for 4 cycles. Folinic acid administered 400 mg/m\^2 IV infusion over 2 hours; oxaliplatin administered 85 mg/m\^2 IV infusion over 2 hours). A maximum of 12 doses of oxaliplatin was permitted. After mFOLFOX6 treatments, participants could continue to receive 5-FU and folinic acid on Days 1, 15 and 29 of each cycle at the investigator's discretion or until the participant met the study treatment discontinuation criteria. Each cycle was approximately 42 days.

mFOLFOX6+ Placebo

Participants received an IV infusion (minimum 2-hour infusion) of placebo matched to zolbetuximab on C1D1, followed by subsequent doses every 3 weeks starting from C1D22 until study treatment discontinuation criteria were met. Participants also received up to 12 treatments of mFOLFOX6 (or components if some were discontinued due to toxicity) over 4 or more cycles. mFOLFOX6 was administered on Days 1, 15, and 29 of each cycle (5-fluorouracil: 400 mg/m\^2 IV bolus over 5-15 minutes followed by 2400mg/m\^2 over 46-48 hours continuous IV infusion every 2 weeks for 4 cycles. Folinic acid: 400 mg/m\^2 IV infusion over 2 hours; oxaliplatin: 85 mg/m\^2 IV infusion over 2 hours). A maximum of 12 doses of oxaliplatin was permitted. After mFOLFOX6 treatments, participants could continue to receive 5-FU and folinic acid on Days 1, 15, and 29 of each cycle at the investigator's discretion or until study treatment discontinuation criteria were met. Each cycle was approximately 42 days.
