Outcome Measures

Primary Outcome Measures

  1. Occurrence of major infections [52 weeks]

    Major infection for this trial is defined as: Bacterial and/or viral infections resulting in death Bacterial and/or viral infections, which are microbiologically documented (MDI) or clinically documented (CDI) requiring treatment with anti-infectives; upper respiratory tract infections, bronchitis, lower urinary tract infections, bacterial skin infections and stomatitis (MDI or CDI) are considered major only if they require treatment with antiinfectives AND hospitalization or hospitalization prolongation. Fever of unknown origin (FUO) requiring hospitalization or hospitalization prolongation

Secondary Outcome Measures

  1. Overall infection rate [52 weeks]

    Infection rate for all infections

  2. Frequency of prophylaxis with anti-infectives [52 weeks]

    Inclusive of antibacterials and antivirals

  3. Duration of prophylaxis with anti-infectives [52 weeks]

    Inclusive of antibacterials and antivirals

Exclusion Criteria:
  1. IgG treatment within 3 months prior to Screening.

  2. Antibiotic prophylaxis and/or treatment within 7 days prior to current CLL treatment start (with the exception of trimethoprim-sulfamethoxazole [TMP/SMX], diaminodiphenyl sulfone [dapsone] and pentamidine inhalation).

  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 with life-expectancy of less than two years.

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

  8. Body weight >140 kg.

  9. Eastern Cooperative Oncology Group (ECOG) performance score of >2 (Appendix 1).

  10. Female patients of childbearing potential unwilling to use a protocol-required method of contraception (as per protocol section 7.3.9 b) from the Screening Visit throughout the study treatment period and for 30 days following the last dose of study drug.

  11. Human immunodeficiency virus (HIV) infection at Screening (defined for the study as positive HIV antibody test).

  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.
