Bottom Line: Reducing dosing frequency was statistically significantly important to patients; however, it was relatively less important than medication cost or clinical outcomes.On average, patients preferred once-weekly to once-daily dosing.For younger patients and patients not currently on treatment, once-weekly dosing may provide additional incentive to initiate and adhere to antihyperglycemic treatment; however, additional research will be required to confirm this hypothesis.

ABSTRACT

Introduction: Previous research has demonstrated a correlation among patient preferences, dosing burden, and medication nonadherence, a well-recognized challenge in type 2 diabetes mellitus (T2DM). The objective of this study was to elicit preferences for alternative dosing regimens for oral antihyperglycemic therapies among patients with T2DM and to quantify differences in dosing preferences among patients with different characteristics.

Methods: Preferences for dosing of oral antihyperglycemic drugs (OAD) were evaluated by surveying patients with T2DM in the United States (US). Survey participants were adult US patients with T2DM who were taking no or only 1 OAD and no injectable therapies. Each patient completed a web-enabled discrete-choice experiment (DCE) including a series of 8 pairs of hypothetical OAD profiles. Each profile was defined by reductions in average glucose, dosing schedule (e.g., once-weekly, once-daily, or twice-daily dosing), chance of mild-to-moderate gastrointestinal side effects, frequency of hypoglycemia, weight change, incremental risk of congestive heart failure, and cost. Each participant also answered a direct question about dosing preference. Random-parameters logit was used to analyze the DCE data. Prespecified subgroups were analyzed.

Results: Of 2,262 patients invited to participate, 923 were included in the analysis (mean age 63 years, 45% male, 79% white). Reducing dosing frequency was statistically significantly important to patients; however, it was relatively less important than medication cost or clinical outcomes. On average, patients preferred once-weekly to once-daily dosing. Patients not currently taking an OAD had a stronger preference for once-weekly dosing than patients on treatment (P = 0.012). Patients younger than 45 years had a stronger preference for weekly dosing than older patients (P < 0.075).

Conclusions: For younger patients and patients not currently on treatment, once-weekly dosing may provide additional incentive to initiate and adhere to antihyperglycemic treatment; however, additional research will be required to confirm this hypothesis.

Mentions: Following the choice questions, each patient was presented with a direct question about dosing preference (Fig. 2). Specifically, each patient was asked to indicate his or her preferred dosing schedule from four possible dosing schedules, assuming all other treatment characteristics were constant across alternatives.Fig. 2
