^aStudy coordinator/research nurse will inquire about pain medications including names, dosage and frequency; this person also is required to fill out pain medication list form during every clinic visit

^bPre-treatment daily baseline pain and analgesic use for 7 days (at least 4 out of 7 days) is required before treatment initiation. Patients will be asked to report their pain at its worst in the last 24 h, and analgesic use (stable/reduced/increased) by digital version every 2 weeks through Week 28, followed by routine clinic follow up or when they experience new pain during off-visit. A full short version of brief pain inventory (BPI) will be asked at baseline, after Cycle 1, after Cycle 2, and at Week 24

^cPRO-CTCAE survey items will be assessed by digital instruments. Beginning at Week 28, surveys are requested every 3 months for 6 months after the last study treatment administration

^dFollow-up visit evaluation. Every 3 months or as clinically indicated up to one year from the first dose injection or disease progression
