Details and patient eligibility

About

The purpose of this study is to evaluate the safety, pharmacokinetics (PK) and preliminary efficacy of XOMA 052 in subjects with active Type 2 Diabetes Mellitus (T2D).

IV administration of XOMA 052 is likely to improve glycemic control in subjects with T2D by blocking certain receptors.

Inclusion criteria

American Diabetes Association (ADA) diagnostic criteria for T2D: Fasting blood glucose concentration ≥ 126 mg/dL (≥ 7.0 mmol/L) (must be measured within 28 days prior to Day 0) OR Symptoms of hyperglycemia (e.g., thirst, polyuria, weight loss, visual blurring) AND a casual/random plasma glucose value of ≥ 200 mg/dL (≥ 11.1 mmol/L) (must be measured within 28 days prior to Day 0)
HbA1c ≥ 7.5% and ≤ 12% (DCCT standard)
Current T2D of duration > 3 months and ≤ 10 years at Screening
T2D and other diseases must be stable. Stable disease is defined as disease that is judged stable by the investigator and which did not require a change in medications or dosing level on 4 or more consecutive days or 7 days in total within 28 days prior to Day 0.
Age ≥ 18 and ≤ 70 at Screening
Weight ≥ 80 lbs (36.3 kg) and ≤ 325 lbs (147.4 kg)
BMI ≥ 23 and ≤ 36 kg/m2
For female subjects of child-bearing age, a negative serum pregnancy test. For subjects with reproductive potential, a willingness to utilize adequate contraception and not become pregnant (or have their partner[s] become pregnant) during the study.
Agrees not to change diet and exercise regimen during the trial

Exclusion criteria

Use of the following medications: Anti-inflammatory therapy other than aspirin ≤ 100 mg/day; Immunosuppressive treatment; Beta 2 and non-selective adrenergic blockers (Note: selective beta 1 blockers are permitted); Thiazolidinediones; Glucagon-like peptide (GLP) agonists including DPP4 inhibitors
Change in medication for diabetes within 28 days prior to Day 0, defined as a change in dosing level on 4 or more consecutive days or 7 days in total
Fasting C-peptide < 400 pM (< 1.20 μg/L)
Hemoglobin < 8.0 g/dL, WBC < 3.0 × 103/mm3, platelet count < 125 × 103/mm3, creatinine > 1.5 mg/dL, AST/ALT > 2 × ULN, alkaline phosphatase > 2 × ULN
Positive for GAD65 or IA-2 auto-antibodies
History or evidence of thyroid abnormalities, including active hyperthyroidism needing medication. Subjects with hypothyroidism will not be excluded if their TSH level has been normal during the 3 months prior to Screening.
Abnormal T3, T4, thyroglobulin, or TSH levels
Known HIV antibody, hepatitis B surface antigen, and/or hepatitis C antibody
History of malignancy within 5 years prior to study entry other than carcinoma in situ of the cervix, or adequately treated, non-metastatic squamous or basal cell carcinoma of the skin
History of severe allergic or anaphylactic reactions to humanized or murine monoclonal antibodies
History of tuberculosis, positive PPD test, active atopic disease requiring medication, or asthma
Infectious disease: CRP > 30 mg/L, fever, or infection requiring treatment with antibiotics within 3 weeks prior to Screening; History of recurrent infection or predisposition to infection; Active leg or foot ulcer
Immunodeficiency
Female subjects who are pregnant, planning to become pregnant during the course of the study, or breast-feeding
History or symptoms of a demyelinating disease
Clinically significant diabetic macular edema and/or proliferative diabetic retinopathy by history or fundoscopy
Receipt of a live (attenuated) vaccine within 3 months prior to Screening
Major surgery within 28 days prior to Day 0
Participation in an investigational drug or device trial within 30 days prior to Screening
Use of a therapeutic monoclonal antibody within 90 days prior to Screening
Any condition which, in the opinion of the investigator, would jeopardize the subject's safety following exposure to the study drug
