A Phase 1 Open-label Trial to Evaluate the Safety, Tolerability, Pharmacodynamics, Pharmacokinetics, and Immunogenicity of Subcutaneous VIS171 in Participants With Autoimmune Disease(s)

Sponsor

Otsuka Pharmaceutical Development & Commercialization, Inc.

Enrollment

30 participants

Start Date

Mar 17, 2025

Study Type

INTERVENTIONAL

Conditions

Systemic Lupus Erythematosus (SLE)Alopecia Areata (AA)Immune-mediated Focal Segmental Glomerulosclerosis (FSGS)

Summary

The purpose of this trial is to measure safety and tolerability of subcutaneous (SC) VIS171 in combination with standard of care in participants with autoimmune disease(s). The total duration of the clinical trial for each participant will be up to approximately 9 to 12 months.

Eligibility

Min Age: 18 YearsMax Age: 75 Years

Inclusion Criteria10

Estimated glomerular filtration rate (eGFR) \>30 milliliters/minute/1.73 square meters (mL/min/1.73 m\^2) at the screening visit.
For SLE participants:
Participant has a confirmed diagnosis of SLE according to European League Against Rheumatism/American College of Rheumatology SLE classification criteria ≥ 24 weeks prior to signing the informed consent form (ICF).
For AA participants:
Current scalp involvement between 25% and 95%, inclusive (Severity of Alopecia Tool \[SALT\] score between 25 and 95, inclusive), at screening.
Current episode of AA is of duration \> 24 weeks (without evidence of spontaneous terminal hair regrowth at the time of screening and first treatment, i.e., no more than 10% regrowth), but ≤ 5 years from onset of current episode of severe scalp hair loss.
For FSGS participants:
Prior biopsy (no time limit) showing histologic minimal change disease (MCD), FSGS, or MCD/FSGS spectrum.
History of at least one prior episode of nephrotic syndrome, defined as 24-hour urine protein \> 3.5 grams per day (g/day) and serum albumin \< 3.5 grams per deciliter (g/dL).
History of steroid responsive nephrotic syndrome, including participants who achieved complete remission, partial remission, had a course of steroid dependent nephrotic syndrome or relapsing nephrotic syndrome (all defined as per the managing physician at the time of the episode).

Exclusion Criteria11

Receipt of high-dose corticosteroid therapy within 4 weeks prior to screening as either (a) intravenous (IV) pulse corticosteroid therapy or (b) daily oral corticosteroid therapy of ≥ 1 milligrams per kilogram (mg/kg) or up to 40 milligrams per day (mg/day) prednisone (or equivalent).
Receipt of blood products within 6 months prior to screening.
Previous exposure to VIS171 or any other drug targeting interleukins (IL)-2 or the IL-2 receptor or T regulatory cells.
History of or current diagnosis of catastrophic or severe anti-phospholipid syndrome (APS) within 1 year prior to signing ICF. SLE participants with APS adequately controlled by anticoagulant are eligible. SLE participants who are found to be triple positive for anti-phospholipid antibodies at screening (without clinical APS) will be excluded unless they are on stable anti-thrombotic therapy.
Known primary immunodeficiency disorder.
Participant has a history of Class V lupus nephritis.
Receipt of anifrolumab, tumor necrosis factor-alpha monoclonal antibodies (\[TNF\]-α mAb), immunoglobulins (IV/SC) plasmapheresis, or any other immunosuppressants (calcineurin inhibitors, Janus kinase \[JAK\] inhibitors or other kinase inhibitors), other than hydroxychloroquine, mycophenolic acid (MPA)/mycophenolate mofetil (MMF) and corticosteroids, within 6 months prior to screening.
Participant has concomitant hair loss of another form, including but not limited to traction alopecia, central centrifugal cicatricial alopecia, lichen planopilaris, frontal fibrosing alopecia, or androgenetic alopecia.
Participant has received (1) Within 12 weeks prior to Day 1: Systemic therapies (oral or injection), such as corticosteroids, JAK inhibitors, methotrexate, calcineurin inhibitors, oral minoxidil, low-dose IL-2 and topical immunotherapies such as psoralen plus UVA (PUVA) , diphenylcyclopropenone (DPCP), dinitrochlorobenzene (DNCB), intralesional steroids or (2) Within 4 weeks prior to Day 1: Other topical therapies, such as topical minoxidil, clobetasol etc. These therapies will also not be allowed during this trial.
Steroid resistant nephrotic syndrome defined as absence of history of at least 1 episode of complete or partial remission following at least 12 weeks of full dose corticosteroid therapy.
Receipt of anifrolumab, TNF-α mAb, immunoglobulins (IV/SC) plasmapheresis, or any other immunosuppressants (JAK inhibitors or other kinase inhibitors).
