Single-arm Study of IgPro20 in Adults With Secondary Immune Deficiencies Due to Hematologic Malignancies Treated With B-cell Targeting Chimeric Antigen Receptor T-cell and T-cell Redirecting Therapies

This is a prospective, multicenter, open-label, single-arm study to assess the efficacy, safety, and pharmacokinetics (PK) of IgPro20 in adults with hematologic malignancies treated with B-cell targeting Chimeric antigen receptor T-cell (CAR T-cell) and T-cell redirecting therapies (such as T-cell engager bispecific antibody \[TCE BsAb\] therapy). The primary objective is to demonstrate that true annualized rate of serious bacterial infection (SBIs) is less than (\<) 1.0. This study includes two cohorts: 1. Loading Cohort: Participants with serum immunoglobulin G (IgG) \< 500 milligrams per deciliter (mg/dL) at Screening, with or without ongoing immunoglobulin replacement therapy (IgRT) during Screening, who must have received five doses of IgPro20 during the Initial Treatment Period. 2. Maintenance-only Cohort: Participants with serum IgG greater than or equal to (≥) 500 mg/dL and ongoing IgRT at Screening, who must have received one dose of IgPro20 during the Initial Treatment Period.

Observational Study of Subcutaneous Immunoglobulin (Cutaquig) in Patients With Primary and Secondary Immunodeficiency.

This study will assess the relative safety, tolerability, and participant satisfaction in participants using the rapid manual push method with Cutaquig®. The hypothesis being that treatment with Cutaquig® by rapid manual push method will improve the safety, tolerability and patient satisfaction of participants with PID or SID. Cutaquig® by rapid push is already approved in Canada and has proven to be efficacious in preventing significant infection. However, relative safety, tolerability, and patient satisfaction have not been studied in these patients. The information gained from this study will improve the safety and tolerability knowledge database and will support the optimal use of Cutaquig® - thus benefitting both physicians and patients.
