Study Endpoints

Primary Endpoints

Change From Baseline in 2 Hour Mixed Meal-stimulated C-peptide Area Under Curve (AUC) (Normalized for 120-minute Time Interval) at Month 12
Baseline (Day 1) and Month 12

C-peptide is a protein that shows how much insulin the body is producing. For 3 days before the mixed meal tolerance test participants were asked to eat a balanced diet. The test was performed only when the finger-stick blood glucose level was above 70 mg per deciliter (mg/dL) and no higher than 200 mg/dL. Mixed meal-stimulated C-peptide AUC was the area under the C-peptide/time curve from time 0 to 120-minutes, calculated using the trapezoidal rule. This AUC was normalized for time interval by dividing it by 120-minutes (the number of minutes over which it was determined), and was adjusted by inclusion of Baseline C-peptide AUC as a covariate in the analysis. Baseline was defined at Day 1. Change from Baseline was calculated by subtracting the value at Month 12 from the Baseline value.

Number of Participants With Adverse Events (AEs) Related to Cytokine Release Syndrome (CRS)
Up to Day 14

An AE is any untoward medical occurrence in a participant or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. On treatment AEs have been reported. Safety Population comprised of all participants who received at least one dose of study treatment.

Epstein-Barr Virus (EBV) Viral Load Detection
Week 3, Week 6, Week 8, Week 12, Week 24 and Week 96

Blood samples were collected for analysis of EBV viral load and detection was done by polymerase chain reaction (PCR).

Number of Participants With Abnormal Laboratory Results
Up to Month 24

Blood samples were collected to analyze the laboratory parameters which included alanine aminotransferase (ALT), albumin, alkaline phosphatase (ALP), aspartate aminotransferase (AST), bilirubin, calcium, chloride, creatinine, direct bilirubin, glucose, potassium, protein, sodium, urate, urea nitrogen, basophil, eosinophil, mean corpuscular haemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), mean corpuscular volume (MCV), erythrocytes, haematocrit, haemoglobin, leukocytes, lymphocytes, monocytes, neutrophils, platelets and reticulocytes.

Number of Participants With Increase in QT Interval Corrected for Heart Rate (QTc)
Up to Month 24

12-lead electrocardiograms (ECGs) were obtained in semi-supine position after 5 minutes rest for the participants at indicated time points to measure QTc.

Number of Participants With Abnormal Vital Sign Results
Up to Month 24

Vital signs were measured in semi-supine position after 5 minutes rest for the participants at indicated time points. Vital signs included systolic, diastolic blood pressure, pulse rate and respiratory rate

Frequently asked questions about Otelixizumab

What is Otelixizumab used for?

Otelixizumab is an investigational monoclonal antibody being developed for Type 1 Diabetes Mellitus. It is designed to treat this autoimmune condition, which affects the body's ability to regulate blood sugar. The drug is currently in clinical development and has not been approved by regulatory authorities.

Who makes Otelixizumab?

Otelixizumab is being developed by GSK plc, a global pharmaceutical company listed on the stock exchange under the ticker GSK. The company is conducting clinical trials to evaluate the drug's safety and efficacy in patients with Type 1 Diabetes Mellitus.

What phase is Otelixizumab in?

Otelixizumab is in Phase 3 clinical development for Type 1 Diabetes Mellitus. It has completed a Phase 3 trial, known as DEFEND-2, which enrolled 179 participants. The drug remains investigational and is not yet approved for commercial use.

What clinical trials is Otelixizumab in?

Otelixizumab has been studied in three completed clinical trials. These include NCT00946257, a Phase 1 study in Belgium with 33 participants; NCT01123083, a Phase 3 trial in Italy with 179 participants; and NCT02000817, a Phase 1 study in Belgium with 30 participants. All trials focused on Type 1 Diabetes Mellitus.

How does Otelixizumab work?

Otelixizumab is a monoclonal antibody that targets specific immune cells involved in the autoimmune destruction of insulin-producing cells in Type 1 Diabetes Mellitus. By modulating the immune response, it aims to preserve remaining beta-cell function and potentially slow disease progression.
