Long-Term Outcomes of Teplizumab in Routine Clinical Care
(AL1GN)
What this study is about
This is an observational, forward-looking group of participants study designed to evaluate the outcomes after teplizumab treatment in participants with Stage 2 Type 1 Diabetes (T1D) for delaying the onset of Stage 3 T1D. The study will monitor participants receiving teplizumab as part of routine clinical care across multiple sites.
View original scientific description
This is an observational, prospective cohort study designed to evaluate the outcomes after teplizumab treatment in participants with Stage 2 Type 1 Diabetes (T1D) for delaying the onset of Stage 3 T1D. The study will monitor participants receiving teplizumab as part of routine clinical care across multiple sites. Additionally, patient-reported outcomes (PROs) will be evaluated to further assess the treatment's impact on participant's quality of life including emotional and psychosocial aspects associated with T1D. This approach will provide a more comprehensive understanding of how the treatment performs over time and across diverse patient populations, providing valuable insights into the sustained effects of teplizumab and offering a real world picture of its impact on the long-term management of T1D.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Participants who have received at least 1 teplizumab infusion within 6 weeks prior to enrollment.
- Participants must have a confirmed diagnosis of Stage 2 T1D according to the treating physician at the time of the first infusion of teplizumab. (Note: Participants who progress to Stage 3 T1D by Week 6 will still be eligible, provided they were in Stage 2 at the time of the first teplizumab infusion.) • Participants (or their legal guardians, as applicable) who provide appropriate written or electronic informed consent/assent as applicable for the age of the participant and as per local regulations.
Exclusion criteria
- Participants who had participated in a previous clinical trial for teplizumab.
- Participants enrolled in a clinical trial within 6 months prior to study enrollment. (Note: Participants enrolled in other observational studies may be included.) The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
