About this study

Official title: Phase II Multiple Dose Treatment of Type 1 Diabetes Mellitus With hOKT3gamma1(Ala-Ala)

This is a phase II study to examine the clinical and immunological effects of humanized FcR non-binding anti-CD3 mAb in participants with Type 1 diabetes mellitus (T1DM), and to develop this therapy to prevent the immune destruction leading to β cell loss.

Read the detailed description

This is a 2-arm, open-label phase II trial involving 0 or 3 cycles of treatment 6 months apart with hOKT3γ1 (Ala-Ala), over the first year of disease in participants with new onset T1DM. Each cycle consists of 12 daily doses of hOKT3γ1 (Ala-Ala).

Participants will be randomized in a ratio of 2:1 to either the experimental arm or the control arm and will be stratified by study site.

To be eligible, participants must be: male or female between 7-30 years of age, diagnosed with T1DM within the past 6 weeks, have a body weight ≥26 kg at the time of enrollment and have detectable anti-GAD, anti-ICA512/IA-2, or insulin autoantibodies (if the participant has been on insulin ≤10 days).

Participants randomized to the experimental group will start the first cycle of hOKT3γ1 (Ala-Ala) within 4-8 weeks of T1DM diagnosis. Each participant randomized to the experimental group will receive 3 cycles of drug treatment, separated by 6 months each. Each cycle consists of 12 days of drug treatment.

Both groups will undergo the Mixed Meal Stimulated C-Peptide Test and receive blood draws for mechanistic studies on the same schedule.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing hOKT3gamma1(Ala-Ala) in people with Diabetes Mellitus, Type 1, run by National Institute of Allergy and Infectious Diseases (NIAID) at 3 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 8 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Adverse events related to drug lot). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

4-hour C-peptide AUC (time frame: 24 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00806572, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Feb 2017.
