Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The drug being studied is called VRS-859, and it is administered subcutaneously (into tissue under the skin).
It is being studied for its effectiveness in the treatment of Type 2 Diabetes Mellitus.
a) There are 5 potential dose groups (12.5mg, 25mg, 50mg, 100mg and 150mg) of VRS-859. There is also a placebo (a simulated medical intervention) that patients may receive.
b) Patients will be assessed in groups of 11, beginning with the lowest dose of VRS-859 or placebo.
c) Doses will be administered once only. Patients will receive either one, two or three injections depending on the cohort.
d) Each patient will be monitored at regular intervals for a period of 30 days after treatment and then followed-up 60 days after treatment.

Only 1 dose group will be dosed at a time, once safety and tolerability are assessed for that group and it is deemed safe to continue, the next dose group will be dosed.
Intervention code [1] 257340 0
Treatment: Drugs
Comparator / control treatment
Each patient that enters will have roughly a 28% percent chance of receiving non-active drug (placebo). The active drug will be administered in the same fashion as the placebo to maintain blinding. The placebo will be composed of normal saline (0.9% w/v Sodium Chloride-NaCl) and 20 mm L-Histidine (0.154M2) at pH 5.5. The placebo will be dosed as a single administration (may be more than one injection), as per VRS-859.
All follow-up assessments and patient monitoring will be identical to that of patients who receive VRS-859.
Control group
Placebo

Outcomes
Primary outcome [1] 259348 0
Primary Outcome 1: To determine the safety and tolerability of a single dose of VRS-859 in Type 2 Diabetes Mellitus patients.
Timepoint [1] 259348 0
Timepoint 1: VRS-859 is administered as a single dose on Day 1. Safety and tolerability will be regularly assessed with the patient confined to the site for 48 hrs after administration. Out-patient follow-up visits will then be performed on Days 4, 8, 11, 15, 18, 22, 25 and 30. A follow-up visit will then take place at Day 60 after study drug is administered.
Safety and Tolerability will be measured by vital signs, an electrocardiogram (ECG), a physical exam, blood and urine tests performed through-out all visits.
Secondary outcome [1] 265814 0
Secondary Outcome 1: To determine the single dose pharmacokinetics of VRS-859 administered subcutaneous(SC) in patients with Type 2 diabetes mellitus.
Timepoint [1] 265814 0
Timepoint 1: Pharmacokinetics and pharmacodynamics will be assessed via blood samples taken at multiple times throughout the study (Pre dose: 24 and 2 hrs; Post dose: 30mins, 1hr, 2hr, 4hr, 8hr, 12hr, 24hr, 36hr, 48hr and Days: 4, 8, 11, 15, 18, 22, 25 and 30).
Secondary outcome [2] 265815 0
Secondary Outcome 2: To assess the activity of VRS-859 by measurement of fasting plasma glucose (FPG) and response to oral Glucose Tolerance Test (GTT) at selected times post-dose in patients with Type 2 diabetes mellitus.
Timepoint [2] 265815 0
Timepoint 2: Glucose Tolerance Test (GTT) will be assessed via blood samples taken multiple times throughout the study (Pre dose and at 15min intervals post-dose for 2 hours)
Secondary outcome [3] 265816 0
Secondary Outcome 3: To evaluate post-Glucose Tolerance Test (GTT) glucose excursions following administration of a single SC dose of VRS-859.
Timepoint [3] 265816 0
Timepoint 3: Glucose Tolerance Test (GTT) will be assessed via blood samples taken multiple times throughout the study (Pre dose and at 15min intervals post-dose for 2 hours)

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Eligible patients will already have been diagnosed with Type 2 Diabetes Mellitus. Providing patients meet most of the eligibility criteria, the site principal study doctor or delegate will approach them regarding the study.
Patients will be given information and the informed consent form and will be asked to take this home and discuss it with whoever they choose. If patients are happy to participate, they will be brought back to see the principal study doctor who will sign the consent form with them, and then the patient can be screened.
The site staff will log in to an interactive web response system called IWRS. The patient who will be screened will be entered into the system (date of birth, gender, initials). This IWRS system will randomly assign them (like flipping a coin) to a cohort (treatment group) and will also assign them a study number.
This information will be emailed to the site staff that logged the call. This IWRS system will also allocate the specified drug vials to be administered to the patient. The site staff will not know whether active drug or placebo is being given, they will however know which vials to select for treatment.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The site will know which dose level the patient will receive, though not study drug versus placebo.
Once all screening procedures have been completed and results obtained, the information is put into an automated system which will assign the patient a number and will randomly assign them (like flipping a coin) to treatment or placebo.
