Brief Summary:
This phase II trial studies how well xisomab 3G3 works in preventing catheter-associated blood clots (thrombosis) in patients with cancer receiving chemotherapy. Many patients with cancer develop blood clots from their catheters and can have pain, swelling, and other symptoms. They also often require blood thinners, which can increase the risk of bleeding. Xisomab 3G3 is type of drug called a monoclonal antibody that may prevent blood clots caused by a catheter in patients receiving chemotherapy.

Condition or disease Intervention/treatment Phase
Lymphoma Malignant Solid Neoplasm Plasma Cell Myeloma Drug: Xisomab 3G3 Phase 2

Detailed Description:

PRIMARY OBJECTIVE I. To determine the efficacy of xisomab as measured by the incidence of catheter-associated thrombosis (CAT) in individuals with a central venous catheter.

SECONDARY OBJECTIVE:

I. To evaluate the safety and tolerability of xisomab 3G3 in cancer patients with a PICC or indwelling catheter.

EXPLORATORY OBJECTIVE:

I. Assessment of drug exposure and catheter occlusions leading to medical intervention.

OUTLINE:

Patients receive xisomab 3G3 intravenously (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.

After completion of study, patients are followed up for 60 days.

Primary Outcome Measures :
  1. Incidence of catheter-associated thrombosis (CAT) [ Time Frame: Up to end of treatment visit (day 18) ]
    The incidence of overall CAT (inclusive of both symptomatic and asymptomatic events) will be assessed and reported with 95% confidence interval.


Secondary Outcome Measures :
  1. Incidence of major and clinically-relevant bleeding [ Time Frame: 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).

  2. Incidence of xisomab 3G3-associated adverse events (AEs) [ Time Frame: 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.


Other Outcome Measures:
  1. Quantification of coagulation measures: platelet count [ Time Frame: Up to end of treatment visit (day 18) ]
    Presented with descriptive statistics.

  2. Quantification of coagulation measures: Prothrombin time/international normalized ratio (PT/INR) [ Time Frame: Up to end of treatment visit (day 18) ]
    Presented with descriptive statistics.

  3. Quantification of coagulation measures: Activated partial thromboplastin time (aPTT) [ Time Frame: Up to end of treatment visit (day 18) ]
    Presented with descriptive statistics.

  4. Xisomab 3G3 pharmacokinetics [ Time Frame: Up to end of treatment visit (day 18) ]
    Presented with descriptive statistics.

  5. Time to detection of thrombosis [ Time Frame: From xisomab 3G3 infusion up to end of treatment visit (day 18) ]
    Will be reported for those (expected few) subjects with symptomatic CAT.

  6. Time to clot symptoms [ Time Frame: From xisomab 3G3 infusion up to end of treatment visit (day 18) ]
    Will be reported for those (expected few) subjects with symptomatic CAT.

  7. Proportion of patients that had a catheter occlusion requiring medical intervention [ Time Frame: Up to end of treatment visit (day 18) ]
    Results will be presented with descriptive statistics.
