What this phase means
Phase 2: researchers already know a roughly safe dose (from phase 1). This stage asks whether the treatment actually helps the condition, and watches side effects more closely.
Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.
What the registry says happens
If you join, the listed intervention(s) are Tamibarotene, or Placebo. The registry lists allocation as randomized. This study will measure the effect of 12 weeks of treatment with tamibarotene compared with dummy treatment (placebo) on N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels in patients with heart failure with preserved ejection fraction (HFpEF).
They plan to enroll about 90 people at 4 sites. Taking part typically means taking a study drug (or dummy pill) plus check-ins.
