Title: A Multicenter, Randomized, Double-Blind, Phase 3 Trial to Evaluate the Efficacy and Safety of Saxagliptin Added to Insulin Monotherapy or to Insulin in Combination With Metformin in Subjects With Type 2 Diabetes Who Have Inadequate Glycemic Control on Insulin Alone or on Insulin in Combination With Metformin
Brief Summary: The purpose of this study is to compare the effects of saxagliptin with those of placebo as add-on therapy to insulin and insulin with metformin in improving glycemic control at 24 and 52 weeks.


Options:
A: Inclusion Criteria:

* Type 2 diabetes
* Treated with oral anti-diabetic (OAD) drugs for at least 3 months
* Treated with one or more OAD and in moderate to poor glycemic control
* Body Mass Index (BMI) less than or equal to 45.0 kg/m2

Exclusion Criteria:

* Treatment with insulin within the last three months prior to the trial except due to intercurrent illness, at the discretion of the Investigator
* Any serious medical condition
* Treatment with any drug that could interfere with glucose level
B: Inclusion Criteria:

* Subjects diagnosed with type 2 diabetes and treated with oral anti-diabetic drugs (OADs) for at least 3 months
* HbA1c: 7.0-11.0 % (both incl.) in subjects on OAD monotherapy. 7.0-10.0 % (both incl.) in subjects on OAD combination therapy
* Body Mass Index (BMI) less than or equal 40 kg/m2

Exclusion Criteria:

* Subjects treated with insulin within the last three months
* Subjects with any serious medical condition
* Females of child bearing potential who are pregnant, breast-feeding or have the intention of becoming pregnant or not using adequate contraceptive methods
* Subjects using any drug (except for OADs), which in the Investigator's opinion could interfere with the glucose level (e.g. systemic corticosteroids)
C: Inclusion Criteria:

* Type 2 diabetes mellitus
* Must have been taking a stable dose of basal or premixed insulin for 8 weeks or longer prior to screening
* If taking metformin, must have been taking the same daily dose for 8 weeks or longer prior to screening
* Insulin type should be intermediate- or long-acting (basal) or premixed (premixed formulation may include short- or rapid-acting insulin as 1 component).
* Inadequate glycemic control (A1C of 7.5% to 11.0%, inclusive)
* Body mass index of 45 kg/m² or lower
* Fasting C-peptide level of 0.8 ng/mL or higher

Exclusion Criteria:

* Symptoms of poorly controlled diabetes, including but not limited to marked polyuria and polydipsia with greater than 10% weight loss during the last 3 months prior to screening or other signs and symptoms
* History of diabetic ketoacidosis or hyperosmolar nonketotic coma
* Women of childbearing potential unable or unwilling to use acceptable birth control
* Women who are pregnant or breastfeeding
* Active liver disease
* Anemia
* Chronic or repeated intermittent corticosteroid treatment (participants receiving stable doses of replacement corticosteroid (except dexamethasone) therapy may be enrolled)
* Use of short- or rapid-acting insulin
* Significant cardiovascular history defined as: myocardial infarction, coronary angioplasty or bypass graft, valvular disease or repair, unstable angina pectoris, transient ischemic attack, or cerebrovascular accident
* Congestive heart failure
* Unstable or rapidly progressing renal disease
* History of alcohol or drug abuse within the previous year
* History of hemoglobinopathies
* Unstable major psychiatric disorders
* Immunocompromised status
D: Inclusion Criteria: Main Inclusion Criteria:

1. Is male or female and ≥18 and \<75 years old at time of informed consent.
2. Has a HbA1c of ≥7.5% and ≤10.5% based on central laboratory results from Visit 1, with individual need for therapy escalation.
3. Currently treated with a stable maximum tolarated dose (MTD) (≥1500 mg/day) of metformin therapy for at least 8 weeks prior to Enrolment visit.
4. Has a BMI of ≤45 kg/m2 at Enrolment visit.
5. Has a C-peptide laboratory value of ≥1.0 ng/mL (0.33 nmol/L; 333.3 pmol/L) based on central laboratory results from Visit 1.

Main, Exclusion Criteria:

1. Clinically diagnosed with Type I diabetes, known diagnosis of maturity onset diabetes of the young (MODY), or secondary diabetes mellitus or known presence of glutamate decarboxylase 65 (GAD65) antibodies.
2. Patients who, in the judgment of the Investigator, may be at risk for dehydration or volume depletion that may affect the patient's safety and/or the interpretation of efficacy or safety data.
3. Clinically significant cardiovascular disease or procedure within 3 months prior to Enrolment or expected to require coronary revascularization procedure during the course of the study.
4. Concomitant treatment with loop diuretics
