Ixekizumab Diabetes Intervention Trial (I-DIT)

• Status: Not yet recruiting
• Trial end date: 2027-12-01
• Target enrollment: 0
• Participant gender: All

Summary

Although the clinical onset of type 1 diabetes (T1D) is acute, the progression of T1D occurs over many years often in a patchy manner with inflammation in certain lobes of the pancreas, leaving other lobes unaffected and long-lasting beta cells remain functional decades after diagnosis. Psoriasis share several aspects with T1D, e.g. the patchy inflammatory infiltrate consisting of tissue-resident memory (TRM) T cells, leaky blood vessels that facilitate leukocyte migration and the increased risk for systemic conditions. Moreover, interleukin (IL)-17 has shown to be increased in both persons with psoriasis and T1D. Activation of IL-17/IL-22 pathway is viewed to be both a hallmark of psoriasis and human T1D. Ixekizumab, an anti-IL17 biological agent, has shown marked therapeutic value in the treatment of subjects with psoriasis in several randomized trials and is currently an approved clinical therapy. Due to the many similarities in the current view of pathogenesis and manifestation of T1D and psoriasis it is possible that Ixekizumab can also influence the disease process of T1D.

Criteria

Inclusion criteria:

• Signed informed consent and expected cooperation of the patients for the treatment and follow up must be obtained and documented according to ICH GCP, and national/local regulations before trial activities are begun.

• Must be willing and capable of taking the study drugs and meet for tests and follow up as described.

• Diagnosed Type 1 Diabetes (E10.9) less than 8 weeks.

• First injection of insulin maximum 8 weeks prior to screening.

• Aged 18-35 years old.

• Presence of antibodies to at least one of the following antigens: insulin, GAD-65, IA-2 and ZnT8.

• Remaining stimulated peak C-peptide ≥ 0.20 nmol/L.

• Male subjects agree to use a reliable method of birth control during the study.

• Female subjects:

Participants of childbearing age or childbearing potential who are sexually active who test negative for pregnancy must be counseled and agree to use either 1 highly effective method of contraception or 2 acceptable methods of contraception combined for the duration of the study and for at least 12 weeks following the last dose of study drug or remain abstinent during the study and for at least 12 weeks following the last dose of study drug.

If the highly effective contraceptive methods are contraindicated or strictly declined by patient, acceptable birth control methods may be considered. These may include combination of both of the following methods:

• Male or female condom with spermicide

• Cap, diaphragm, or sponge with spermicide

1. Highly effective methods of contraception (use 1 form):

1. combined oral contraceptive pill and mini-pill

2. NuvaRing®

3. implantable contraceptives

4. injectable contraceptives (such as Depo-Provera®)

5. intrauterine device (such as Mirena® and ParaGard®)

6. contraceptive patch-ONLY women <198 pounds or 90 kg

7. abstinence from sex

8. vasectomy-for men in clinical studies

2. Effective methods of contraception (use 2 forms combined)

• male condom with spermicide

• female condom with spermicide

• diaphragm with spermicide

• cervical sponge

• cervical cap with spermicide

Females who are not of childbearing potential include those who have undergone or who have:

• female sterilization

• hysterectomy

• menopause

• Müllerian agenesis (Mayer-Rokitansky-Küster-Hauser syndrome [also referred to as congenital absence of the uterus and vagina])

Exclusion Criteria:

• Contraindications to Ixekizumab.

• Treatment with any oral or injected glucose-lowering agents other than insulin.

• A history of haemolytic anaemia or significantly abnormal haematology/coagulation results at screening.

• Participation in other clinical trials with a new chemical entity within the previous 3 months.

• Subjects with severe obesity (BMI>35 kg/m2).

• Active serious or chronic infections (ie: in case patient had a serious infection (eg pneumonia, cellulitis), has been hospitalized, has received intravenous antibiotics for an infection within 12 weeks prior to screening visit, had a serious bone or joint infection within 24 weeks before screening visit, has ever had an infection of an artificial joint.

• Tuberculosis.

• History of HIV, hepatitis B or C.

• Active or recurrent fungal infection.

• Subjects with myocardial infarction, stroke, unstable angina or heart failure last 6 months.

• Current clinically significant cardiac arrhythmias as verified by ECG.

• For female subjects: Positive pregnancy test, presently breast-feeding, or unwillingness to use effective contraceptive measures for the duration of the study and 3- months after discontinuation.

• For male subjects: intent to procreate during the duration of the study or within 3 months after discontinuation or unwillingness of their partner to use effective contraceptive measures for the duration of the study and 4 months after discontinuation.

• Any history of malignancy the last 5 years except for completely resected squamous or basal cell carcinoma of the skin.

• Administration of live attenuated vaccine(s) (LAV) within 2 months of enrolment. Or intended use of LAV during the treatment period.

• The investigator judges that the clinical diagnosis of T1D set is incorrect or uncertain (needs to be confirmed by discussion with experienced diabetologist if excluding due to this criterion).

• Allergy against ingredients of the investigational products.

• Known allergy or hypersensitivity to any biologic therapy (active substance or excipients) that would pose an unacceptable risk to the patient if participating in the study.

• Presence of serious disease or condition, which in the opinion of the investigator makes the patient non-eligible for the study.

• Liver injury criteria: patients with active hepatobiliary diseases or at screening having alanine aminotransferase (ALT) or aspartate aminotransferase (AST) > 2.5 times the upper limit of normal (>2.5 x ULN)

• Laboratory abnormalities at screening:

1. Neutrophil count < 1,500 cells/ μL (=1,5 *109 cells/ L)

2. Platelet count < 100,000 cells/ μL (= 100 *109 cells/ L)

3. Hemoglobin < 8.5 g/dL (= <85 g/L) (males) and <8g/dL (= <80 g/L) (women)
