up to 21 days following a single IV infusion of XTX202 on Cycle 1
Systemic Clearance (CL) of Intact XTX202
時間枠：up to 21 days following a single IV infusion of XTX202 on Cycle 1

Systemic clearance (CL) of intact XTX202 following a single IV infusion of XTX202.

In the analysis set used for PK, participants are assigned to a treatment group based on the initial dose received.

In the Participant Flow module, participants are assigned to a treatment group based on the highest dose received. One participant in Phase 2 Part 2B initially received XTX202 1.4 mg/kg, then increased the dose to 4.0 mg/kg at a later cycle and was therefore included in the XTX202 4.0 mg/kg dose group. One participant in Phase 1 Part 1B initially received XTX202 2.8 mg/kg, then increased the dose to 4.0 mg/kg at a later cycle and was therefore included in the XTX202 4.0 mg/kg dose group.
up to 21 days following a single IV infusion of XTX202 on Cycle 1
