Effect of Canagliflozin on Blood Pressure and Adverse Events Related to Osmotic Diuresis and Reduced Intravascular Volume in Patients With Type 2 Diabetes Mellitus
Bibliographic record
Abstract
The effects of canagliflozin, a sodium glucose co-transporter 2 inhibitor, on blood pressure (BP) and osmotic diuresis- and intravascular volume reduction-related adverse events (AEs) were evaluated using pooled data from four placebo-controlled, phase 3 studies in patients with type 2 diabetes mellitus (T2DM; N=2313). At baseline, 1332 (57.6%) patients were taking an antihypertensive medication. Canagliflozin 100 mg and 300 mg provided reductions (95% confidence interval [CI]) from baseline in systolic BP (SBP) compared with placebo (-4.3 mm Hg [-5.0 to -3.5], -5.0 mm Hg [-5.8 to -4.2], and -0.3 mm Hg [-1.2 to 0.5], respectively) and in diastolic BP (DBP; -2.5 mm Hg [-2.9 to -2.0], -2.4 mm Hg [-2.9 to -1.9], and -0.6 mm Hg [-1.1 to -0.02], respectively). Placebo-subtracted reductions (95% CI) in SBP with canagliflozin 100 mg and 300 mg were -4.0 mm Hg (-5.1 to -2.8) and -4.7 mm Hg (-5.8 to -3.5) and reductions in DBP were -1.9 mm Hg (-2.6 to -1.2) and -1.9 mm Hg (-2.6 to -1.1), respectively. Compared with the overall population, patients with elevated baseline SBP (≥140 mm Hg) had numerically greater absolute SBP reductions (95% CI) with canagliflozin 100 mg and 300 mg and placebo (-12.8 mm Hg [-15.2 to -10.5], -14.2 mm Hg [-16.4 to -12.0], and -6.8 mm Hg [-9.1 to -4.5], respectively). Numerically greater DBP reductions were seen in patients with DBP ≥90 mm Hg at baseline (-5.9 mm Hg [-8.2 to -3.6], -9.0 mm Hg [-11.1 to -6.9], and -7.4 mm Hg [-9.6 to -5.1], respectively). In patients with elevated SBP at baseline, placebo-subtracted reductions (95% CI) in SBP with canagliflozin 100 mg and 300 mg were -6.0 mm Hg (-9.1 to -2.9) and -7.4 mm Hg (-10.4 to -4.4), respectively. Placebo-subtracted changes in DBP were 1.5 mm Hg (-1.6 to 4.5) and -1.6 mm Hg (-4.5 to 1.2), respectively, in those with elevated DBP at baseline. Canagliflozin 100 mg and 300 mg were associated with increased incidence of osmotic diuresis-related AEs (e.g., pollakiuria [increased urine volume] and polyuria [increased urine frequency]) vs placebo (6.7%, 5.6%, and 0.8%). The incidence of intravascular volume reduction-related AEs (eg, orthostatic hypotension and postural dizziness) was low across groups (1.2%, 1.3%, and 1.1%). In summary, canagliflozin was associated with reduced BP in patients with T2DM across a range of baseline BPs, with increased incidence of AEs related to osmotic diuresis but not intravascular volume reduction.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
