Brief summary
The purpose of the study is to assess the tolerability, safety, and pharmacokinetics of HYQVIA with ramp-up and no ramp-up dosing in healthy adult participants.
Detailed description
This study will comprise of Part 1 and Part 2. Each study part will consist of three treatment arms (Part 1 \[approximately 24 participants\]: Treatment Arms 1-3 and Part 2 \[approximately 24 participants\]: Treatment Arms 4-6). Treatment arms will be initiated in parallel within each study part. Each participant will participate in only one treatment arm. After participants in Treatment Arms 1-3 (Study Part 1) will complete Week 9, the tolerability and, safety data through Week 9 will be reviewed by a safety review team. (Participants in arms 1-3 will continue in the study as the safety review is being completed.) Once the safety review for Arms 1-3 (Study part 1) will be completed and approved, Treatment Arms 4-6 (Study Part 2) will begin.

|---|---|---|
| Number of Participants Who Tolerated All Initiated HYQVIA Infusion | From start of the study drug administration up to Week 9 | A tolerability event was considered to have occurred if an infusion was tolerable. An infusion was considered tolerable if the infusion rate was not reduced, or the infusion was not interrupted or stopped, due to an adverse event (AE) related to HYQVIA infusion.

Outcome results
Primary
Number of Participants Who Tolerated All Initiated HYQVIA Infusion
A tolerability event was considered to have occurred if an infusion was tolerable. An infusion was considered tolerable if the infusion rate was not reduced, or the infusion was not interrupted or stopped, due to an adverse event (AE) related to HYQVIA infusion. Tolerability was measured in terms of the number of participants for which the infusions was tolerable. Number of participants who tolerated all initiated HYQVIA Infusion were reported.
Time frame: From start of the study drug administration up to Week 9
Population: The safety set included all enrolled participants who received at least 1 dose of HYQVIA.

Number of Participants Who Developed Binding and Neutralizing Antibodies to Recombinant Human Hyaluronidase PH20 (rHuPH20)
Binding antibodies are responsible for binding to a pathogen and alerting the immune system to its presence so white blood cells can be sent to destroy it. The antibody level (titer) in the blood tells health care provider whether or not participant been exposed to an antigen, or something that the body thinks is foreign. A neutralizing antibody (NAb) is an antibody that is responsible for defending cells from pathogens, which are organisms that cause disease. The number of participants who developed binding and neutralizing antibodies to rHuPH20 were reported.
Time frame: From start of the study drug administration up to Week 25
Population: The safety set included all enrolled participants who received at least 1 dose of HYQVIA.
