A Study of TAK-881 in Healthy Adults

Phase 1

Completed

• Conditions: Healthy Volunteers
• Interventions: Biological: TAK-881

• Registration Number: NCT05059977
• Lead Sponsor: Takeda

Brief Summary

The main aims of this study are to check for side effects from TAK-881 in healthy adults and to learn how much TAK-881 they can receive without getting side effects from it.

During the study, participants will receive one infusion of TAK-881 under the skin (subcutaneous infusion) on Day 1 at a lower dose level followed by participants receiving one infusion of higher dose levels with ongoing safety monitored by the doctor to ensure optimal tolerability and safety.

Participants will stay in the clinic for 4 days and will come back after 4 weeks. A follow up visit will take place 12 weeks after the TAK-881 infusion.

• Known history of alcohol or other substance abuse within the last year.

• Donation of blood within 60 days, or blood products (e.g., plasma or platelets) within 2 weeks prior receiving the first dose of IP.

• Participants will be excluded if abnormal hematology, chemistry, and other laboratory values are greater than (>)10% above the upper limit of normal (ULN) or >10% below the lower limit of normal (LLN) except for liver function tests and absolute neutrophils. Participants will be excluded if any of the following laboratory parameters meet the criteria below:

  • Absolute neutrophil count less than (<) 1.5* 10^9 cells/liter
  • Liver function: alanine aminotransferase (ALT) greater than or equal to (>=) 1.5* ULN, aspartate aminotransferase (AST) >=1.5* ULN, alkaline phosphatase (ALP) >=1.5* ULN, or total bilirubin >=1.5 milligram per deciliter (mg/dL)

• Participants will be excluded if any other laboratory values are outside the reference range and are clinically significant per investigator's judgment.

• Participants who, within 30 days prior to the first dose of IP:

  • Have participated in another clinical study involving IG products within 12 months of screening.
  • Have used an IP (or 5 half-lives, whichever is longer).
  • Have been enrolled in a clinical study (including vaccine studies or has been vaccinated with approved product) that, in the investigator's opinion, may impact this study. Participants who have received any vaccine (including live attenuated vaccines and COVID-19 vaccines) during the last 30 days before dosing will be excluded. No live attenuated virus vaccines are allowed during the study until the end of the follow-up period.
  • Have had any substantial changes in eating habits, as assessed by the investigator.

• Confirmed systolic blood pressure >139 millimeter of mercury (mmHg) or <89 mmHg and diastolic blood pressure >89 mmHg or <49 mmHg.

• A positive screen for alcohol or drugs of abuse at screening or Day -1 (D-1).

• A positive human immunodeficiency virus (HIV), hepatitis C virus (HCV), or ongoing/active hepatitis B infection at screening. Participants with immunity to hepatitis B from either active vaccination or from previous natural infection are eligible to participate in the study.

• Smoking more than 5 cigarettes or equivalent per day, unable to stop smoking during confinement in the clinical research center (CRC).

• Severe dermatitis or anatomical abnormality that would interfere with TAK-881 administration or endpoint assessments. Note: The skin at the administration site should not be covered by tattoos.

• Current use of any herbal or homeopathic preparations is not permitted.

• Unable or unwilling to discontinue antihistamines or medications with antihistamine properties, sedatives, anxiolytics, systemic steroids, or topical steroids or antibiotics on any area below the chest for a minimum of 48 hours prior to infusion visit and through 72 hours post infusion.

• Current or relevant history of hypercoagulable conditions (e.g., Protein C, Protein S, and antithrombin III deficiency), thrombotic/thromboembolic events or venous thrombosis.

Arm && Interventions

Group	Intervention	Description
TAK-881 0.4 g/kg (in-line warmed)	TAK-881	Participants will receive a single dose of TAK-881 comprising of 0.4 gram per kilogram (g/kg) (in-line warmed) Immune Globulin Subcutaneous (IGSC), 20 percent (%) at progressively increased infusion rates and Recombinant Human Hyaluronidase (rHuPH20) dose of 80 unit per gram (U/g) immunoglobulin G (IgG) on Day 1 of the study treatment period.
TAK-881 1.0 g/kg (un-warmed)	TAK-881	Participants will receive a single dose of TAK-881 comprising of 1.0 g/kg (un-warmed) IGSC, 20% at progressively increased infusion rates and rHuPH20 dose of 80 U/g IgG on Day 1 of the study treatment period.
TAK-881 1.0 g/kg (in-line warmed)	TAK-881	Participants will receive a single dose of TAK-881 comprising of 1.0 g/kg (in-line warmed) IGSC, 20% at progressively increased infusion rates and rHuPH20 dose of 80 U/g IgG on Day 1 of the study treatment period.

Primary Outcome Measures

Name	Time	Method
Number of Participants With Tolerability Events Related to Infusion of TAK-881 Per Infusion Site	Up to Day 4	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 any treatment-emergent adverse event (TEAE) related to TAK-881. Number of participants with tolerability events related to infusion of TAK-881 per infusion sites (1 and 2) were reported.

Secondary Outcome Measures

Name	Time	Method
Number of Participants With Positive Binding Anti-Drug Antibodies (ADA) and Neutralizing Antibodies to rHuPH20	Baseline up to Week 13	Positive binding ADA was defined as titer greater than or equal to (\>=) 1:160. Neutralizing antibodies were only tested if binding ADA titer was \>= 1:160. Number of participants with positive binding ADA and neutralizing antibodies to rHuPH20 were reported.
Number of Participants Who Achieved Maximum Tolerable Infusion Rate Per Infusion Site	Day 1 up to Day 4	The maximum tolerable infusion rate achieved referred to the administration of IGSC, 20% at progressively increasing infusion rates and was defined as the highest infusion rate achieved at which the infusion was tolerable (i.e., no stopping, interruption, or infusion rate reduction due to a TAK-881-related TEAE). The maximum tolerable infusion rate for Infusion Site 2 depended on the planned volume according to the stepwise infusion rate escalation regimen. Number of participants who achieved maximum tolerable infusion rate per infusion sites (1 and 2) for each infusion rate (30, 60, 120, 180, and 300 milliliter per hour \[mL/hour\]) were reported.
Number of Participants With TEAEs	From the start of study drug administration up to Week 13	A TEAE was defined as any event emerged or manifested at or after the initiation of treatment with an Investigational product (IP) or medicinal product or any existing event that worsened in either intensity or frequency following exposure to the IP or medicinal product. Any clinically significant treatment-emergent changes in clinical laboratory measurements and vital signs were recorded as TEAEs. Number of participants with TEAEs were reported.
Time to Deliver the Total Infused Volume Per Infusion Site	At Day 1	Time to deliver (in minutes) the total infused volume was calculated as (stop date/time of IGSC 20% administration) - (start date/time of rHuPH20 administration). Time to deliver the total infused volume per infusion sites (1 and 2) were reported.
Total Volume Infused Per Infusion Site for rHuPH20 and IGSC	At Day 1	Total volume infused per infusion sites (1 and 2) for rHuPH20 and IGSC were reported.
