Faster Aspart Versus Insulin Aspart as Part of a Basal-Bolus Regimen in Inadequately Controlled Type 2 Diabetes: The onset 2 Trial.

OBJECTIVE: This multicenter, double-blind, treat-to-target, phase 3 trial evaluated the efficacy and safety of fast-acting insulin aspart (faster aspart) versus insulin aspart (IAsp) in adults with type 2 diabetes receiving basal insulin and oral antidiabetic agents. RESEARCH DESIGN AND METHODS: The primary end point was HbA1c change from baseline after 26 weeks' treatment. After an 8-week run-in to optimize basal insulin, subjects were randomized (1:1) to mealtime faster aspart (n = 345) or IAsp (n = 344), titrated using a simple daily patient-driven algorithm, plus insulin glargine U100 and metformin. RESULTS: HbA1c change was -1.38% (faster aspart) and -1.36% (IAsp); mean HbA1c was 6.6% for both groups. Faster aspart demonstrated noninferiority versus IAsp in reducing HbA1c (estimated treatment difference [ETD] [95% CI] -0.02% [-0.15; 0.10]). Both treatments improved postprandial plasma glucose (PPG) control; the PPG increment (liquid meal test) was statistically significant in favor of faster aspart after 1 h (ETD [95% CI] -0.59 mmol/L [-1.09; -0.09]; -10.63 mg/dL [-19.56; -1.69]; P = 0.0198), but not after 2-4 h. Change from baseline in fasting plasma glucose, body weight, and overall severe/blood glucose-confirmed hypoglycemia rates (rate ratio [RR] [95% CI] 1.09 [0.88; 1.36]) were similar between treatments. Postmeal hypoglycemia (0-2 h) rates were 2.27 (faster aspart) and 1.49 (IAsp) per patient-year of exposure (RR [95% CI] 1.60 [1.13; 2.27]). CONCLUSIONS: Faster aspart and IAsp were confirmed noninferior in a basal-bolus regimen regarding change from baseline in HbA1c. Faster aspart improved 1-h PPG with no differences in 2-4-h PPG versus IAsp. Overall hypoglycemia rates were similar except for an increase in 0-2-h postmeal hypoglycemia with faster aspart.

The effect of dose titration and dose tapering on the tolerability of desvenlafaxine in women with vasomotor symptoms associated with menopause.

OBJECTIVE: To determine whether titrating up and tapering down of desvenlafaxine (administered as desvenlafaxine succinate) improves its tolerability in postmenopausal women with vasomotor symptoms (VMS). METHODS: In the 1-week titration phase, participants received desvenlafaxine 100 mg/d (no titration), desvenlafaxine 50 mg/d, desvenlafaxine 25 mg/d (4 days) then 50 mg/d (3 days), or desvenlafaxine 25 mg/d. Participants then received open-label desvenlafaxine 100 mg/d for 15 weeks. In the 2-week taper phase, participants received placebo, desvenlafaxine 50 mg/d then placebo (7 days each), desvenlafaxine 50 mg/d then 25 mg/d (7 days each), or desvenlafaxine 50 mg/d every other day. Primary endpoints included nausea incidence during the first 2 weeks of treatment and Discontinuation-Emergent Signs and Symptoms (DESS) Checklist total scores after taper weeks 1 and 2. RESULTS: Nausea incidence was significantly lower for the desvenlafaxine 25 mg/d (19%) and 50 mg/d (22.6%) titration regimens vs. no titration (35.2%; p=0.004 and p=0.035, respectively). At taper week 1, mean DESS scores were significantly lower for desvenlafaxine 50 mg every other day (2.26, p<0.001), 50/25 mg/d (2.28, p<0.001), and 50 mg/d-placebo (1.84, p<0.001) taper regimens vs. no taper (7.07). At week 2, the mean DESS total score was significantly higher for the desvenlafaxine 50 mg/d-placebo regimen vs. no taper (4.46 vs. 2.44, respectively; p=0.009). Desvenlafaxine 50 mg every other day was the least tolerated of the taper regimens. CONCLUSIONS: Titration regimens may improve tolerability of desvenlafaxine 100 mg/d in postmenopausal women with VMS. Taper regimens of desvenlafaxine 50 mg/d-placebo or 50/25-mg/d, were better tolerated than abrupt discontinuation or desvenlafaxine 50 mg given every other day taper regimen.
