Measure
Supportive Care (Xisomab 3G3)
Patients receive xisomab 3G3 IV or via catheter within 48 hours of catheter placement. Patients then receive standard of care chemotherapy 2 days later. After approximately 2 weeks, patients undergo standard of care ultrasound for possible CAT. Xisomab 3G3: Given IV or via catheter

PRIMARY outcome

Timeframe: Up to end of treatment visit (day 18)

Population: Eight of nine participants underwent screening ultrasound for catheter thrombosis. One patient had their catheter removed prior to screening ultrasound.

The incidence of overall CAT (inclusive of both symptomatic and asymptomatic events) will be assessed and reported with 95% confidence interval.

Incidence of Catheter-associated Thrombosis (CAT)
1 Participants

SECONDARY outcome

Timeframe: Up to end of follow-up (60 days from time of administration)

Bleeding will be defined using the International Society of Thrombosis and Hemostasis definition of major bleeding for clinical investigations of anti-hemostatic medicinal products in nonsurgical patients (i.e., fatal bleeding, critical organ bleeding such as central nervous system bleeding, or bleeding causing a fall in hemoglobin of 20 g/L or more) and clinically relevant non-major bleeding (i.e., bleeding that does not fit the former definition of major bleeding but prompts medical attention). The incidence of major and clinically relevant non-major bleeding, along with 95% confidence interval, will be assessed using the safety analysis set (all patients who are exposed to the single dose of study drug).

SECONDARY outcome

Timeframe: Up to end of follow-up (60 days from time of administration)

Descriptive statistics of safety will be presented using Common Terminology Criteria for Adverse Events (CTCAE) version (v) 5.0 using the safety analysis set (all patients who are exposed to the single dose of study drug). All on-study AEs, treatment-related AEs, serious adverse events (SAEs), and treatment-related SAEs will be tabulated using worst grade per National Cancer Institute (NCI) CTCAE v5.0 criteria by system organ class and preferred term. On-study lab parameters including hematology, chemistry, liver function, and renal function will be summarized using worst grade NCI CTCAE v5.0 criteria.
