Patient-reported outcomes in transition from high-dose U-100 insulin to human regular U-500 insulin in severely insulin-resistant patients with type 2 diabetes: analysis of a randomized clinical trial.

ABSTRACT: Initiation and titration of human regular U-500 insulin (U-500R) with a dosing algorithm of either thrice daily (TID) or twice daily (BID) improved glycemic control with fewer injections in patients with type 2 diabetes treated with high-dose, high-volume U-100 insulin. The objective of this analysis was to compare patient-reported outcomes between U-500R TID and BID treatment groups in this titration-to-target randomized, clinical trial.In this 24-week, open-label, parallel trial, 325 patients were randomized to TID (n?=?162) or BID (n?=?163) U-500R after a 4-week lead-in period (screening). The Treatment Related Impact Measure-Diabetes (TRIM-D) and EQ-5D-5L questionnaires were administered at screening, baseline/randomization, and endpoint (24 weeks). The Visual Analog Scale-Injection Site Pain (VAS-ISP) was assessed at baseline/randomization, 12 weeks, and endpoint.The TRIM-D showed statistically significant improvements in overall scores from baseline to endpoint for both BID and TID groups, most domains in the TID group, and all domains in the BID group. The BID group achieved better scores than the TID patients in overall and in treatment burden, daily life, and compliance domains (p?

Project description:OBJECTIVE | Human regular U-500 insulin (U-500R) is concentrated insulin with basal and prandial activity that can be used as insulin monotherapy. The goal of this study was to better understand treatment patterns (total daily dose [TDD] and concomitant medications), adherence, and persistence in real-world patients treated with U-500R. DESIGN AND METHODS | We selected patients from the Truven Health MarketScan database who initiated U-500R between 2010 and 2013. We collected data for three periods: pre-index (12 months before initiation), post-index (12 months after initiation or until a gap of ≥60 days in U-500R claims), and follow-up (12 months after post-index). Data were analyzed using descriptive statistics and a regression model as appropriate. RESULTS | We identified 1,582 patients who met the selection criteria. The median TDD of U-500R during the post-index period was 333 units/day, with 70.0% of patients using 300-400 units/day. During the post-index period, 74.1% of patients had U-500R claims that did not overlap with prescriptions for other insulins, interpreted as U-500R monotherapy. Among patients with ≥1 U-500R fill in the post-index period (n = 1,208), 54.4% had a medication possession ratio (MPR, a measure of adherence) ≥80%. Although 849 patients had a gap of ≥60 days in U-500R claims in the post-index period, 602 of those resumed U-500R in the follow-up period. Of the 733 patients who had no gap in U-500R claims in the post-index period, 286 had a gap of ≥60 days in claims in year 2, and 447 continued with U-500R treatment beyond 2 years. CONCLUSION | These results demonstrate that U-500R was commonly used as insulin monotherapy, with a median TDD >300 units/day. Compared with published, relevant studies of other insulins, U-500R showed similar or greater adherence and persistence rates. These new data may help guide clinical decision-making when choosing insulin therapy for patients requiring high doses of insulin.

Project description:BackgroundPatient-reported outcome measures (PROMs) are commonly-used surrogates for clinical outcomes in cancer research. When researching severe diseases such as cancer, it is difficult to avoid the problem of incomplete questionnaires from drop-outs or missing data from patients who pass away during the observation period. The aim of this exploratory study was to explore patient characteristics and the patient-reported outcomes associated with the time-to-dropout.MethodsIn an Oncological Social Care Project (OSCAR) study, the condition of the participants was assessed four times within 12 months (t0: baseline, t1: 3 months, t2: 6 months, and t3: 12 months) by validated PROMs. We performed competing-risk regressions based on Fine and Gray's proportional sub-distribution hazards model for exploring factors associated with time-to-dropout. Death was considered a competing risk.ResultsThree hundred sixty-two participants were analyzed in the study. 193 (53.3%) completed a follow-up after 12 months, 67 (18.5%) patients dropped out, and 102 patients (28.2%) died during the study period. Poor subjective social support was related to a higher risk of drop-out (SHR = 2.10; 95%CI: 1.01-4.35). Lower values in health-related quality of life were related to drop-out and death. The sub-scales global health status/QoL, role functioning, physical functioning, and fatigue symptom in the EORTC QLQ-C30 were key characteristics of early drop-out.ConclusionSeverely affected cancer patients with poor social support and poor quality of life seem more likely to drop out of studies than patients with higher levels of social support and a better quality of life. This should be considered when planning studies to assess advanced cancer patients. Methods of close continued monitoring should be actively used when patient experiences a substantial deterioration in their health-related quality of life and symptoms during the study. Results for such studies have to be interpreted with caution in light of specific drop-out mechanisms.Trial registrationOSCAR study was registered to the German Clinical Trials Register (DRKS-ID: DRKS00013640 ). Registered 29 December 2017.
