What was measured
Observed serum concentrations of mezagitumab was reported.
Analysis population: Safety analysis set included participants who received at least 1 dose, even if incomplete, of study drug. Here "number analyzed" signifies participants evaluable at specified time-point.
Groups in this outcome
Phase 1b, Part 1: TAK-981 60 mg BIW + Mezagitamab 600 mg
Participants received TAK-981 60 mg, infusion, intravenously, twice weekly on Days 1, 4, 8, 11 and 15, and mezagitamab 600 mg, injection, subcutaneously, once weekly on Days 1, 8, 15 and 22 during Cycles 1 and 2, then once every 2 weeks during Cycles 3 through 6, further once every 4 weeks, until disease progression or unacceptable toxicity, or until any other discontinuation criterion is met, whichever occurs first. Each Cycle length was 28 days.

Each Cycle length was 28 days.
Phase 1b, Part 1: TAK-981 120 mg BIW + Mezagitamab 600 mg
Participants received TAK-981 120 mg, infusion, intravenously, twice weekly on Days 1, 4, 8, 11 and 15, and mezagitamab 600 mg, injection, subcutaneously, once weekly on Days 1, 8, 15 and 22 during Cycles 1 and 2, then once every 2 weeks during Cycles 3 through 6, further once every 4 weeks, until disease progression or unacceptable toxicity, or until any other discontinuation criterion is met, whichever occurs first. Each Cycle length was 28 days.
Phase 1b, Part 1: TAK-981 120 mg QW + Mezagitamab 600 mg
