Treatment of Type 1 Diabetes With Anti-OX40L Bispecific With Anti-TNF Activity In a Single Nanobody® Molecule

Running, not enrolling · Phase 2 · Has a placebo group

Conditions studied: Type 1 Diabetes Mellitus

In brief

This is a randomized, placebo-controlled, parallel group, multicenter, double-blind Phase 2a, 2-arm study. The goal of this Phase 2a study is to assess safety and efficacy of brivekimig in comparison to placebo to preserve β-cell function in participants with recently diagnosed Stage 3 type 1 diabetes (T1D) on insulin therapy. The study design comprises 2 parts: in Part A adult participants (18 to 35 years of age at screening) and in Part B adolescent and young adult participants (age range 12 to 21 years) will be randomized into brivekimig and placebo groups. Approximately 84 participants will be included with randomization ratio 3:1 (active:placebo). The study includes a screening period (3 to 5 weeks), a double-blind treatment period of 52 weeks and a safety follow-up of 26 weeks.

Who can join

Age: 12 and older, up to 35. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Participant must be 18 to 35 y.o. inclusive, at the time of signing the informed consent in order to be enrolled in Part A. Participant must be 12 to 21 y.o. inclusive, at the time of signing the informed consent in order to be enrolled in Part B.
• Participants who meet the criteria of T1D according to American Diabetes Association (ADA 2024).
• Initiated exogenous insulin replacement therapy not longer than 90 days prior to Screening visit at which random C-peptide will be assessed.
• Receiving insulin hormone replacement therapy:
• Participants must be positive for at least 1 of the following T1D autoantibodies confirmed by medical history and/or obtained at study Screening:
• Glutamic acid decarboxylase (GAD-65)
• Insulinoma Antigen-2 (IA-2)
• Zinc-transporter 8 (ZnT8) or
• Insulin (if obtained not later than 10 days after exogenous insulin therapy initiation)
• Have random C-peptide levels ≥0.2 nmol/L determined at Screening.

You may not qualify if…

• Participants are excluded from the study if any of the following criteria apply:
• Serious systemic viral, bacterial or fungal infection (eg, pneumonia, pyelonephritis), infection requiring hospitalization or intravenous (IV) antibiotics or significant chronic viral (including history of recurrent or active herpes zoster, acute or active cytomegalovirus [CMV], Epstein-Barr Virus [EBV] as determined at Screening), bacterial, or fungal infection (eg, osteomyelitis) 30 days before and during Screening.
• History of invasive opportunistic infections, such as, but not limited to histoplasmosis, listeriosis, coccidioidomycosis, candidiasis, pneumocystis jirovecii, and aspergillosis, regardless of resolution.
• Evidence of active or latent tuberculosis (TB) as documented by medical history and examination, chest X-rays (posterior anterior and lateral), and/or TB testing.
• Evidence of any clinically significant, severe or unstable, acute or, chronically progressive, uncontrolled infection, medical or surgical condition (eg, but not limited to, cerebral, cardiac, pulmonary, renal, hepatic, gastrointestinal, neurologic, or any known immune deficiency), or any condition that may affect participant safety in the judgment of the Investigator (including vaccinations which are not updated based on local regulation).
• History of a systemic hypersensitivity reaction or significant allergies, other than localized injection site reaction, to any humanized mAb. Clinically significant multiple or severe drug allergies, intolerance to topical corticosteroids, or severe post-treatment hypersensitivity reactions (including, but not limited to, erythema multiforme major, linear IgA dermatosis, toxic epidermal necrolysis, and exfoliative dermatitis).
• History of moderate to severe congestive heart failure (New York Health Association [NYHA] Class III or IV), or recent cerebrovascular accident, or any other condition which, in the opinion of the Investigator, would put the participant at risk by participation in the protocol.
• History of demyelinating disease (including myelitis) or neurologic symptoms suggestive of demyelinating disease.
• Has other autoimmune or inflammatory conditions
• Diabetes of forms other than autoimmune T1D that include but are not limited to genetic forms of diabetes, maturity-onset diabetes of the young (MODY), latent autoimmune diabetes of the adult (LADA), secondary to medications or surgery, type 2 diabetes by judgment of the investigator.
• History of malignancy or lymphoproliferative disease other than adequately treated localized carcinoma in situ of the cervix or nonmetastatic squamous cell carcinoma, or nonmetastatic basal cell carcinoma of the skin that was excised and completely cured or any family history in two or more relatives (immediate family) of same cancer (ie, rare cancers, those manifesting at a young age in a parent or sibling, certain genetic-based inheritable cancers).
• Systemic corticosteroids (duration >7 days), adrenocorticotropic hormone 1 month prior to Screening.
• Any IV, intramuscular (IM) or SC administered biologic treatments (mono- or polyclonal antibodies affecting function of immune system), <3 months or <5 half-lives (whichever is longer), prior to randomization.
• Any live (attenuated or viral-vector) vaccine (including but not limited to varicella zoster, oral polio, nasal influenza, rabies) within 3 months prior to randomization or is scheduled in expected period of study (78 weeks after randomization) if this vaccination cannot be safely postponed.
• Any non-live (inactivated, mRNA, recombinant, conjugate, toxoid) vaccine administered less than 14 days prior to randomization.
• Any immunosuppressive therapy within 12 weeks prior to randomization and through 78 weeks after randomization
• Course of Thymoglobulin®, teplizumab or other immunomodulatory treatments at any time
• Any drugs that may be used for treatment of T1D and type 2 diabetes other than insulin including but not limited to metformin, glucagon-like peptide 1 (GLP-1) agonists, sodium-glucose co-transporter-2 and 1 (SGLT2/1) inhibitor, and verapamil within 2 weeks prior to Screening.
• Abnormal laboratory test(s) at Screening
• Participants who have impaired renal function with estimated glomerular filtration rate (eGFR) (using the Modification of Diet in Renal Disease [MDRD] formula) <60 mL/min/1.73 m2, or using the bedside Schwartz equation in the participants under the age of 18 y.o.
