What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to determine if TAK-881 (Human normal immunoglobulin IgG combined with recombinant human hyaluronidase) is safe and well-tolerated for individuals with primary immunodeficiency (PIDD), a condition where the immune system malfunctions. Participants will receive TAK-881 through a regular infusion, which delivers medicine by slowly injecting it into the body. This trial is open to those who participated in an earlier study with TAK-881 and wish to continue. As a Phase 3 trial, it represents the final step before FDA approval, allowing participants to contribute to the potential availability of a new treatment.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the study doctor to understand how your current medications might interact with the trial requirements.

Is there any evidence suggesting that TAK-881 is likely to be safe for humans?

Research has shown that TAK-881 was well-tolerated in earlier studies. In one study, healthy adults received a similar treatment and reported it as generally safe, with most experiencing no serious side effects.

Although this information comes from healthy participants, TAK-881 resembles treatments already approved for other uses, suggesting it might be safe for many people. However, individual experiences can vary. Always consult a doctor with any concerns. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Unlike the standard treatments for primary immunodeficiency, which often involve regular intravenous or subcutaneous immunoglobulin infusions, TAK-881 is delivered via a subcutaneous infusion using investigational needle sets. Researchers are particularly excited because TAK-881 may offer a more convenient dosing schedule—every 12 weeks—compared to the more frequent dosing required by current therapies. Additionally, TAK-881 targets the condition with a potentially improved safety profile by adjusting the dose and interval based on individual patient needs, which could enhance the overall treatment experience.

What evidence suggests that TAK-881 might be an effective treatment for primary immunodeficiency?

Research has shown that TAK-881, also known as hyaluronidase-facilitated subcutaneous immunoglobulin, is designed to help people with primary immunodeficiency (PIDD). This treatment combines immunoglobulin (IgG), a type of antibody, with an enzyme called rHuPH20, which helps the IgG spread more easily under the skin. Studies indicate that IgG replacement therapy, like TAK-881, is crucial for treating PIDD because it helps replace missing or low levels of antibodies. Participants in this trial will receive TAK-881, and previous users have experienced positive results in managing their condition. The treatment is generally well-tolerated and has a safety profile similar to other IgG therapies. ^{2 3 6 7 8}

What Are the Treatments Tested in This Trial?

Interventions

• TAK-881

Trial Overview The safety and tolerance of long-term use of TAK-881 are being tested in this trial. Patients will start with the same dose they ended on in a previous study and can adjust dosage or interval between doses every 2, 3, or 4 weeks as directed by their doctor.

How Is the Trial Designed?

Group I: TAK-881 Experimental Treatment 2 Interventions

Epoch 1: Participants who completed study TAK-881-3001 (NCT05755035) and met eligibility criteria will receive TAK-881 subcutaneous (SC) infusion using investigational needle sets at the same dose and same treatment interval as at the last infusion in TAK-881-3001 (NCT05755035) at Week 1 and at Weeks 13 and Week 25 of study TAK-881-3002. Epoch 2: Participants with anti-rHuPH20 antibody titer \>=1:160 at any time point during Study TAK-881-3001 (NCT05755035) and/or Study TAK-881-3002 Epoch 1, will continue receiving TAK-881 every 12 weeks for up to Week 121. After the first TAK-881 infusion in study TAK-881-3002, the interval and/or the dose may be adjusted only at scheduled site visits at the investigator's discretion.

In a long-term study involving children with primary immunodeficiency diseases, recombinant human hyaluronidase-facilitated subcutaneous immunoglobulin (Ig) showed low rates of serious bacterial infections (0.08/patient-year) and minimal adverse reactions, indicating its safety and tolerability.

The study, which lasted up to 3.3 years, demonstrated that 97.2% of infusions required no changes due to adverse drug reactions, and a significant majority of patients preferred this subcutaneous method over traditional intravenous administration.

Recombinant human hyaluronidase facilitated subcutaneous immunoglobulin treatment in pediatric patients with primary immunodeficiencies: long-term efficacy, safety and tolerability. Wasserman, RL., Melamed, I., Kobrynski, L., et al.[2022]

Both subcutaneous immunoglobulin (SCIG) and hyaluronidase-facilitated SCIG (fSCIG) effectively maintained serum immunoglobulin G (IgG) levels above the protective threshold of 7 g/L in patients with primary immunodeficiency diseases after switching from intravenous immunoglobulin (IVIG).

The study found that while mean IgG trough values were higher in obese patients and lower in pediatric patients compared to adults, these differences (up to 22%) do not necessitate dose adjustments based solely on BMI or age; instead, dosing should be tailored based on previous IVIG doses and individual monitoring.

Subcutaneous immunoglobulin therapy, enhanced with recombinant human hyaluronidase, allows for larger infusion volumes and faster administration rates, making it comparable to intravenous therapy while improving patient comfort.

A phase III clinical trial demonstrated that this enzyme-enhanced subcutaneous method is well tolerated, potentially increasing patient adherence and quality of life compared to traditional intravenous immunoglobulin therapy.

A 31-year-old woman with common variable immunodeficiency (CVID) successfully switched from intravenous immunoglobulin (IVIg) to subcutaneous immunoglobulin (SCIg) administration facilitated by recombinant human hyaluronidase during her pregnancy, allowing for effective treatment every 3-4 weeks.

The treatment was well tolerated and maintained sufficient immunoglobulin G (IgG) levels for both the mother and her newborn, highlighting the importance of patient preference and medical needs in choosing immunoglobulin administration methods during pregnancy.

Recombinant human hyaluronidase (rHuPH20) enhances the absorption and distribution of subcutaneous immunoglobulin G (SCIG) in patients with primary immunodeficiency diseases (PIDD), allowing for fewer and less frequent infusions.

Clinical studies indicate that SCIG facilitated with rHuPH20 (IGHy) is effective in preventing infections and is well-tolerated, significantly reducing the number of infusion sites needed compared to traditional SCIG therapy.

In a study of 30 patients with immunodeficiency diseases, the use of recombinant human hyaluronidase-facilitated subcutaneous immunoglobulin (fSCIG; HyQvia) significantly reduced the rate of infections compared to pre-treatment levels, indicating its efficacy in managing these conditions.

The treatment was found to be safe and well-tolerated, with only mild to moderate adverse events reported, none of which led to treatment discontinuation, allowing patients to self-administer the therapy at home.

Subcutaneous infusions of IgG combined with recombinant human hyaluronidase (rHuPH20) were found to be safe and effective for treating primary immunodeficiency diseases (PIDD) in 83 subjects over a long-term period, with a low rate of adverse events (AEs) and stable infection rates.

The study showed that local adverse events decreased significantly over time, from 3.68 per subject-year in the first year to about 1.50 per subject-year after 30 months, indicating improved tolerance to the treatment with continued use.
