简要总结
RESEARCH HYPOTHESIS
- In subjects with T2DM and HF, effect of canagliflozin will be superior to placebo for the change from baseline in PCWP after a single dose (6 hours post-dose) and after 4 weeks.
- Treatment with canagliflozin will be well tolerated over 4 weeks.
详细描述
This is a randomized, double-blind, placebo-controlled, parallel-group, single-center study (Figure 1). Thirty subjects will be randomized in a 3:2 randomization ratio to canagliflozin 300 mg once daily (QD) or placebo. The study will include a 3-week pretreatment screening phase and a 4-week double-blind treatment phase.
