3. Current major infection or >1 major infection in the previous 6 months before Baseline.

4. History of anaphylaxis or severe systemic response to immunoglobulin, blood or plasma-derived products or any Panzyga component.

5. History of a non-CLL malignancy or other medical condition with life-expectancy of less than two years.

6. Severe liver disease, with signs of ascites and/or hepatic encephalopathy.

7. Severe kidney disease (as defined by estimated glomerular filtration rate [eGFR] <30 mL/min/1.73 m2).

12. Patients found to be chronic carriers of hepatitis B virus (HBV), defined by positive surface antigen (HBsAg), positive Hepatitis B core antibodies (HBcAb) and/or low HBV titers, who will not receive targeted antiviral therapy while undergoing CLL therapy, and patients with active HBV, defined as high HBV titers.

13. Uncontrolled hepatitis C infection at Screening (defined for the study as positive hepatitis virus C [HCV] polymerase chain reaction [PCR]).

14. Pregnant and lactating women.

15. Subjects with a history of thromboembolic events (TEE) such as deep vein thrombosis, pulmonary embolism, myocardial infarction, ischemic stroke, transient ischemic attack, peripheral artery disease (Fontaine IV) within 6 months before Baseline.

16. Planned or ongoing immunosuppressive treatment (other than for CLL or corticosteroids) or other forbidden medication during the entire study duration after study enrollment.

17. Participation in another interventional clinical trial that is either blinded or involves an investigational (not approved) product within 3 months before Baseline or during the course of the clinical study. Participation in observational clinical trials or open-label trials involving an approved product may be permitted after consultation with the medical monitor.

18. Known IgA deficiency with antibodies to IgA.

19. Known blood hyperviscosity, or other hypercoagulable states.
