Tolerability and Safety of Immune Globulin Subcutaneous Solution (IGSC) and rHuPH20 in PID

The original purpose of the study is to assess the long-term safety, tolerability, and practicability of the subcutaneous (SC) treatment with Immune Globulin Subcutaneous Solution (IGSC), 10% facilitated with recombinant human hyaluronidase (rHuPH20) in participants with Primary Immunodeficiency Diseases (PID) who have completed Baxter Clinical Study Protocol No. 160603.

Following a discussion with the FDA, all participants still active in the study stopped treatment with rHuPH20 to assure safety of the participants participating in the study and went into a safety follow-up.

During this safety follow-up period, participants underwent either intravenous (IV) or SC treatment with IGSC, 10%. The IV or SC administration route was at the discretion of the participant and the investigator.

Treatment and study plan

SC treatment with IGSC, 10% with rHuPH20 followed by SC/IGSC, 10% only (safety)

Biological

Participants are to continue on the same doses and treatment intervals of IGSC, 10% adjusted for body weight, and rHuPH20 that were used for the last infusions in Study epoch 2 of Study 160603 (NCT00814320).

After 3 infusions, participants are to change treatment to a 2-week interval, if agreed with participant and investigator.

During this safety follow-up period, participants are treated with IGSC, 10% via the SC route. Treatment occurred once every week. The dose was the weekly equivalent of the most recent IV dose (adjusted per body weight) and multiplied by 1.37.

Primary outcomes

  1. Annual Rate of Serious Bacterial Infections

    Time frame: Throughout the efficacy period only (from 60 to 729 days)

    The point estimate of the annual rate of validated acute serious bacterial infections (VASBIs) per participant per year was provided during subcutaneous (SC) administration of Immune Globulin Subcutaneous Solution (IGSC), 10%, after SC administration of human recombinant hyaluronidase (rHuPH20). This efficacy outcome measure was only applicable prior to the safety follow-up i.e. before discontinuation of rHuPH20.

  2. Annual Rate of All Infections

    Time frame: Throughout the efficacy period only (from 60 to 729 days)

    Annualized rate of infections per participant as defined by MedDRA system organ class (SOC) "infections and infestations". The point estimate of the annual rate of all infections was provided during subcutaneous (SC) administration of Immune Globulin Subcutaneous Solution (IGSC), 10%, after SC administration of human recombinant hyaluronidase (rHuPH20). This efficacy outcome measure was only applicable prior to the safety follow-up i.e. before discontinuation of rHuPH20.

  3. Trough Levels of IgG Maintained During the Study Period in Relation to Dose Frequency

    Time frame: Throughout the efficacy period only (from 60 to 729 days)

    Immunoglobulin (IgG) steady state trough levels were measured in relation to dose frequency by measuring in relation to treatment interval (2-, 3- or 4-week intervals). Initially participants were administered subcutaneous (SC) infusions of Immune Globulin Subcutaneous Solution (IGSC), 10%, after SC administration of human recombinant hyaluronidase (rHuPH20) [or IV infusions of IGSC, 10% only] at the treatment intervals and dose determined by epoch 2 of study 160603 (3- or 4-week intervals). After 3 treatment intervals (either 3- or 4- week intervals), participants changed to a 2-week treatment interval, if agreed with participant and investigator, with the dose adjusted to 1/2 of the 4-week dose or 2/3 of the 3-week dose, whichever was applicable. The rHuPH20 dose was adjusted relative to the new IGSC, 10% dose in order to achieve a dose ratio of 75 U/g IgG. This efficacy outcome measure was only applicable prior to the safety follow-up i.e. before discontinuation of rHuPH20.
