What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This phase 2b trial tests frexalimab, an antibody that calms the immune system, in 192 adults and teens newly diagnosed with type 1 diabetes. The goal is to see if it can preserve the body's ability to produce insulin, reducing reliance on injections. Participants receive frexalimab or placebo for up to 104 weeks, with regular monitoring of insulin production and blood sugar control.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
frexalimab (a monoclonal antibody that blocks CD40L to calm the immune system)
What this could lead to
If it works, this could help people with newly diagnosed type 1 diabetes keep making some of their own insulin longer, reducing how much insulin they need to inject.
What could go wrong
This is a mid-stage trial with only 192 people, so results may not apply to everyone. The drug may not preserve insulin production better than placebo, and there are risks from immune suppression, such as infections.

Inclusion Criteria: * Participants who meet the criteria of T1D according to American Diabetes Association * Initiated exogenous insulin replacement therapy not longer than 90 days prior to screening visit at which random C-peptide will be assessed (V1). * Receiving at least one of the following T1D standard of care (SOC), insulin hormone replacement therapy * one or multiple daily injections (MDI) of basal insulin, prandial insulin and/or premixed insulin, or * continuous subcutaneous insulin infusion (CSII) * 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 visit. * Be vaccinated according to the local vaccination schedule. Any vaccinations should take place at least 28 days prior to randomization for non-live vaccines and at least 3 months prior to randomization for live vaccines. * Contraceptive use by men and women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies * Participants body weight at screening must be at least 20kg. Exclusion Criteria: * Serious systemic viral, bacterial or fungal infection (eg, pneumonia, pyelonephritis), infection requiring hospitalization or 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. * Participants with a 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. Blood testing (eg, QuantiFERON® TB Gold test) is strongly preferred; if not available, any local approved TB test is allowed. * 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, acquired or inherited bone/skeletal disorders including repeated bone fractures for unknown reason, juvenile osteoporosis, osteogenesis imperfecta, osteochondropathies, 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 or current hypogammaglobulinemia. * 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). * Has other autoimmune diseases (eg, rheumatoid arthritis \[RA\], polyarticular juvenile idiopathic arthritis \[pJIA\], psoriatic arthritis \[PsA\], ankylosing spondylitis \[AS\], MS, SLE), that require treatment with biologic drugs (mono or polyclonal antibodies) or systemic corticosteroid therapy (at discretion of investigator). * History, clinical evidence, suspicion or significant risk for thromboembolic events, as well as myocardial infarction, stroke, antiphospholipid syndrome, other prothrombotic disorders and/or participants requiring antithrombotic treatment. * Diabetes of forms other than autoimmune T1D that include but is 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 judgement of the investigator. * History of malignancy of any organ system, treated or untreated, within 5 years of screening, regardless of whether there is evidence of local recurrence or metastases. * Systemic corticosteroids (duration \> 7 days), adrenocorticotropic hormone 1 month prior to screening. * Any IV, IM or SC administered biologic treatments, \< 3 months or \< than 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. * Any non-live (inactivated, mRNA, recombinant, conjugate, toxoid) vaccine administered less than 28 days prior to randomization. * Other medications not compatible or interfering with IMP at discretion of investigator. * Any immunosuppressive therapy within 12 weeks prior to 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 and sodium-glucose co-transporter-2 and 1 (SGLT2/1) inhibitor and verapamil within 2 weeks prior to screening. * Abnormal laboratory test(s) at screening.
