The study was a Phase 2, multicounty, multicenter, non-confirmatory, investigator- and subject masked, randomized, placebo-controlled study to evaluate the safety, tolerability, pharmacokinetics, and efficacy of CFZ533 on preservation of residual pancreatic β-cell function in new onset T1DM in pediatric and young adult subjects.

Inclusion criteria
. Written informed consent, and if needed assent from the child on the trial, must be obtained before any assessment is performed.
. Males and females aged between 12 and 21 years (inclusive, and enrolled in stages) at screening.
. Body weight range from 30 to 125 kg (inclusive).
. Evidence of one or more type 1 diabetes autoantibody(ies) against: glutamic acid decarboxylase (anti-GAD), protein tyrosine, phosphatase-like protein (anti-IA-2); zinc transporter 8 (anti-ZnT8); islet cell (cytoplasmic) (anti-ICA) at screening or baseline in the central laboratory OR historical clinical record of one or more of the T1DM diabetes autoantibodies. As part of the historical record insulin autoantibodies (IAA) may have been used as part of the autoantibody panel but the blood sample must have been obtained prior to or within one week of starting exogenous insulin treatment.
. Able to receive first dose of study drug within 56 days of diagnosis of T1DM (which may be extended to within 100 days of diagnosis in the event a screening assessment needs to be confirmed or vaccine administered).
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Number of Participants With Treatment Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs) During the On-treatment Period
Timeframe: Adverse events were reported from first dose of study treatment to 98 days after last dose, up to a maximum duration of approximately 65 weeks.
2
Normalized Stimulated C-peptide Area Under the Curve (AUC) at Week 52
Timeframe: At Week 52, 10 min prior to ingestion, at start of ingestion, and at 15, 30, 60, 90, and 120 min after consumption of the liquid meal.
. Peak stimulated C-peptide levels ≥0.2 nmol/L (0.6 ng/mL) following standard liquid mixed meal tolerance test (MMTT), to be conducted when the subject is metabolically stable, at least 2 weeks from diagnosis and within 56 days prior to randomization (or within 100 days of diagnosis in the event a screening assessment needs to be confirmed or vaccine is required).
. Study participants are to complete all recommended immunizations with live, attenuated vaccine at least eight weeks prior and killed, inactivated vaccine at least two weeks prior to first dose with study drug and in accordance with local immunization guidelines. In the event a subject has not had all vaccinations recommended according to local guidance, the screening period may be extended beyond 56 days to allow these vaccinations to be administered, but first dose of study drug must be administered within 100 days of diagnosis of T1DM.
. Must be willing to comply with the standard of care for diabetes management.
Exclusion criteria
. Diabetes forms other than auto immune type 1 such as maturity-onset diabetes of the young (MODY), latent autoimmune diabetes of the adult (LADA), acquired diabetes (secondary to medications or surgery), type 2 diabetes by judgement of the investigator.
. Diabetic ketoacidosis within 2 weeks of the baseline MMTT test.
. Polyglandular auto immune disease, Addison's disease, pernicious anemia, celiac sprue. Note: Investigators are not mandated to test for Celiac disease (also known as Sprue). Subjects suspected of having Celiac disease should be tested for the presence of disease, as part of good medical care, as treatment would differ. Treated, stable Hashimoto's thyroiditis is not exclusionary.
. Any of the following abnormal laboratory values at screening: total white blood cell count (WBC) outside the range of 1,500-15,000/mm3 (1.5-15.0 x 109/L), neutrophil count (\<1500/mm3) (\<1.5 X 109 / L), lymphocyte count \<500/mm3 (\<0.5 X 109 / L), hemoglobin (Hgb) \<8.0 g/dL, platelets \<100,000/mm3 (\<100 x 109/L) 5. History of immunodeficiency disorders, such as HyperIgM syndrome; history of recurrent infections suggestive of immunodeficiency disorders.
