Design outcomes

Primary

MeasureTime frame
Main Objective: The primary objective of the research project is to determine the change in the psoriasis area and severity index (?PASI) during 16 weeks of treatment with a dipeptidyl peptidase-4 inhibitor (Januvia®, 100mg daily) in psoriasis patients with type 2 diabetes. This will be compared to the ?PASI in psoriasis patients with type 2 diabetes during 16 weeks of treatment with a comparator (Diamicron®, 80mg to 320mg daily).;Secondary Objective: To determine, and compare, the effects of: 1.16 weeks tmt with Januvia® with Diamicron® on the: a.Incidence of AEs and d/c of one of the IMPs b.Change in QOL scores c.Incidence of achievement of > than 50% reduction in PASI from baseline d.Incidence of PASI-75 & PASI-90 e.Time to achieve PASI-50, PASI-75 & PASI-90 f.Changes in levels of CVD risk factors g.Changes in serum concentrations of cytokines and hormones h.Changes in mononuclear cell expression of immune proteins 2. 32 weeks tmt with Januvia® with 16 weeks Diamicron® followed by 16 weeks Januvia® tmt on the: a.Change in PASI b.Incidence of AEs and d/c of one of the IMPs c.Change in QOL scores d.Incidence of achievement > than 50% reduction in PASI from baseline e.Incidence of PASI-75 & PASI-90 f.Time to achieve PASI-50, PASI-75 & PASI-90 g.Changes in levels of CVD risk factors h.Changes in serum concentrations of cytokines and hormones j.Changes in mononuclear cell expression of immune proteins ;Primary end point(s): The primary efficacy endpoint of the study is the change in the psoriasis area and severity index in psoriasis patients with type 2 diabetes after sixteen weeks of treatment. ;Timepoint(s) of evaluation of this end point: After a 16 week treatment period

Secondary

MeasureTime frame
Secondary end point(s): The secondary efficacy endpoints are: 1. Change in psoriasis area and severity index after 32 weeks of treatment; 2. Incidence of adverse events within 16 and 32 weeks of treatment commencement; 3. Incidence of discontinuation of one of the study investigational medicinal products (IMPs) within 16 and 32 weeks of treatment commencement; 4. Changes in validated quality of life scores (DLQI, EQ-5D, HADS, and HAQ-8) after 16 and 32 weeks; 5. Proportion of patients who achieve a greater than 50% reduction in PASI from baseline (PASI-50) within 16 and 32 weeks; 6. Proportion of participants who achieve PASI-75 and PASI-90 within 16 and 32 weeks; 7. Times taken to achievement of PASI-50, PASI-75 and PASI-90; 8. Changes in levels of cardiovascular disease risk factors (blood pressure, glycaemic measures lipid fractions, weight etc) after 16 and 32 weeks; 9. Changes in serum concentrations of cytokines (CRP, IL-6, TNFa, IL-1ß, IL-10 etc) after 16 and 32 weeks; 10. Changes in serum concentrations of hormones (GLP-1, PYY etc) after 16 and 32 weeks; and 11. Changes in peripheral blood mononuclear cell expression of immune proteins (IL-6, TNFa, IL-10, IL-27, IFN?, IL-17, TLR-4, TLR-2, JNK-1 MCP-1 etc) after 16 and 32 weeks. ;Timepoint(s) of evaluation of this end point: After 16 and 32 weeks treatment.
