despite the availability of a large number of therapeutic agents for the management of type 2 diabetes ( t2d ) , patients continue to present with high levels of glycated hemoglobin a1c ( hba1c ) in actual clinical practice . insulin is the most potent therapy for t2d ; however , physicians often take a conservative approach to insulin dose optimization citing lack of familiarity and the risks of hypoglycemia and weight gain as some of the main concerns associated with its use . it is acknowledged that insulin therapy tailored towards the requirements of individual patients would be more effective in helping patients manage hyperglycemia , while mitigating the risks of hypoglycemia and weight gain . a study by riddle et al . suggests that basal ( fasting ) glucose , rather than postprandial plasma glucose ( pppg ) , tends to contribute more towards overall hyperglycemia at higher hba1c levels in t2d patients . basal insulin therapy could therefore help decrease hyperglycemia in t2d patients by providing additional glycemic control . insulin detemir ( idet ) is a basal insulin analogue with a protracted duration of action compared to neutral protamine hagedorn ( nph ) insulin . idet remains soluble in the subcutaneous depot following injection , which may contribute to its lower within - subject variability with regard to nph insulin and another basal analogue , insulin glargine ( iglar ) . studies have found that idet provides hba1c reductions in t2d patients comparable to those provided by iglar and nph insulin . idet therapy is also associated with significantly less weight gain compared to iglar and nph insulin in t2d management . it has also been noted that glycemic control improved following idet therapy in t2d patients previously treated with other basal insulins in combination with oral glucose - lowering drugs ( oglds ) . in india , the t2d epidemic is widespread with a reported diabetes prevalence of 9.0% in 2011 . by 2030 , the diabetes prevalence is set to increase to 10.6% , marking the urgent need to improve t2d management in the country . in developing nations such as india where diabetic complications are common and a large segment of the population is of working age , the high t2d prevalence can have serious economic implications as well . evidence from randomized controlled trials however , the patient populations of these trials are selected based on restrictive criteria and may not be truly representative of the patients seen in actual clinical practice . large observational studies such as a1chieve , on the other hand , can provide relevant and timely data that would help in gauging patient responses to different therapies in a heterogeneous setting . this sub - analysis of the a1chieve study aimed to determine the clinical safety and effectiveness of insulin detemir in indian patients switched from previous nph insulin or iglar therapy . in the open - label , 24-week , non - interventional a1chievestudy , the clinical safety and effectiveness of the novo nordisk insulin analogs , idet ( levemir ) , biphasic insulin as part 30 ( novomix 30 ) and insulin as part ( novorapid ) in the treatment of t2d was evaluated in routine clinical care . here , the clinical safety and effectiveness of idet was explored in indian patients switched from either iglar or nph insulin . have described the methods and procedures of the a1chieve study in detail . in brief , the prescription of idet was determined by the local physicians , who also supervised all aspects of the patients treatment . the physicians performed all evaluations at routine visits to the local clinics , following which the data were transferred to standard case report forms . indian patients switching therapy from either pre - study iglaror nph insulin to idet were included in this sub - analysis . patients were excluded if they had received treatment with any of the study insulins for more than 4 weeks before the start of the study . pregnant or breastfeeding women were excluded as were those who intended to become pregnant within 6 months from the start of the study . study approval was obtained from the relevant local authorities and signed informed consent was obtained from all patients . the primary outcome measure was the incidence of serious adverse drug reactions ( sadrs ) , including major hypoglycemic events , from baseline to week 24 . secondary outcomes included the number of serious adverse events ( saes ) and the changes in the proportion of patients reporting hypoglycemic events in the 4 weeks before baseline and week 24 . additional outcomes comprised the change from baseline to week 24 in hba1c , fasting plasma glucose ( fpg ) , pppg , systolic blood pressure ( sbp ) , body weight , lipids ( total cholesterol , triglycerides , high - density lipoprotein [ hdl ] cholesterol , and low - density lipoprotein [ ldl ] cholesterol ) and quality of life ( qol ) . qol was determined using the euroqol visual analogue scale ( eq - vas ) that rates an individual 's current health state on a scale of 0 ( worst score ) to 100 ( best score ) . local laboratories were used for laboratory measurements and followed local standardization and quality control procedures . statistical analyses were performed for indian patients switching from pre - study iglar and nph insulin . descriptive statistics ( mean , sd ) and frequency tables ( n , % ) were used to summarize continuous and discrete variables , respectively . the change from baseline to week 24 in the proportion of patients reporting at least one event of hypoglycemia the change from baseline to week 24 for hba1c , fpg , pppg , sbp , body weight , lipids , and qol was analyzed using a paired t - test . no p values are presented as the number of patients analyzed was less than 100 for all endpoints . in the open - label , 24-week , non - interventional a1chievestudy , the clinical safety and effectiveness of the novo nordisk insulin analogs , idet ( levemir ) , biphasic insulin as part 30 ( novomix 30 ) and insulin as part ( novorapid ) in the treatment of t2d was evaluated in routine clinical care . here , the clinical safety and effectiveness of idet was explored in indian patients switched from either iglar or nph insulin . have described the methods and procedures of the a1chieve study in detail . in brief , the prescription of idet was determined by the local physicians , who also supervised all aspects of the patients treatment . the physicians performed all evaluations at routine visits to the local clinics , following which the data were transferred to standard case report forms . indian patients switching therapy from either pre -

optimal at baseline in patients previously treated with iglar and nph insulin . in the gla group , patients had a mean baseline hba1c of 9.9  1.8% , diabetes duration of 9.0  5.7 years and had been taking insulin for an average of 2.6  2.0 years . in the neu group , the mean baseline hba1c level was 9.1  1.2% , diabetes duration was 8.9  6.3 years and patients had been on insulin therapy for an average of 2.5  2.9 years . switching to idet therapy was seen to be well - tolerated in the gla and neu groups with no sadrs , saes , or major hypoglycemic events reported during the study . clinical trials have not identified any difference between idet and iglar with regard to the risk of hypoglycemia . in this sub - analysis , the incidence rate of overall hypoglycemia was 2.80 events per patient - year at baseline and 1.36 events per patient - year at week 24 in the gla group . no nocturnal hypoglycemic events were reported at week 24 in the gla group against an incidence rate of 1.91 events per patient - year at baseline . idet has been noted to have a significantly lower risk association for hypoglycemia than nph insulin in 2 randomized controlled trials in patients with t2d . in the neu group in this study , no events of hypoglycemia were reported at week 24 against a baseline incidence rate of 2.33 events per patient - year . glycemic parameters appeared to improve after 24 weeks in both the gla and neu groups . at week 24 , the mean hba1c was 7.6  0.9% in the gla group and 7.3  0.7% in the neu group . however , these levels still fall short of the internationally recommended hba1c target of < 7.0% . also , the number of patients meeting the hba1c target of < 7.0% at week 24 was low in both groups . most patients ( > 60% ) in both the gla and neu groups followed qd dosing of idet at week 24 , with the remaining patients following bid dosing . in the gla group , the mean daily insulin dose by weight was 0.23  0.09 u / kg at baseline and 0.25  0.12 u / kg at week 24 . in the neu group also , the difference in mean dose between baseline and week 24 was small ( 0.24  0.09 and 0.28  0.09 , respectively ) , suggesting that perhaps the physicians were overly cautious in applying dose titration . it is possible that a more aggressive approach to dose titration may have led to more effective reductions in glycemic levels and more patients achieving the recommended hba1c target at week 24 . a general lack of insulin dose optimization in clinical practice in india has also been identified in the prospective 26-week impact study , which evaluated the effectiveness of the indian insulin guideline on premixed insulin . mean body weights remained very similar from baseline to week 24 in both the gla and neu groups , in line with the known weight - sparing effect of idet therapy . the mean qol also appeared to improve with idet therapy in both groups , in line with the overall a1chieve study results that showed a significant improvement in qol in patients treated with idet . this study may have been limited by the lack of a control group and the possible introduction of recall bias in the reporting of safety data , particularly hypoglycemic events . the small number of patients in this sub - analysis was also a limiting factor . concomitant medication and diet were not restricted ; hence , it was not possible to determine the effect , if any , of non - pharmacological treatment on the study outcomes . the heterogeneity of the local healthcare systems meant that there was no standardization across sites . however , this study provided the opportunity to study the effect of switching therapy from nph insulin and iglar to idet in the routine clinical setting in india . all measurements made by the laboratories followed local standardization procedures and the 24-week duration of the study was considered adequate to determine the preliminary clinical trend following therapy change . data from non - interventional studies such as a1chieve can help bridge the gap between recommended healthcare policies for t2d and actual clinical practice . also , patient education can play a key role in improving compliance to blood glucose monitoring , weight control , diet and exercise . a holistic approach to the treatment of t2d , involving increased patient education , recommendations for diet and exercise and therapeutic strategies that target glycemic levels without increasing the risk of hypoglycemia and weight gain , may be indicated to improve patient compliance and facilitate disease management . in this sub - analysis , idet therapy was noted to be well - tolerated with minimal change in weight and a low risk of hypoglycemia in patients switched from nph insulin and iglar . it would be interesting to note the effect of additional dose titration with idet over a further period of evaluation in a larger patient group .
aim : to explore the clinical safety and effectiveness of insulin detemir ( idet ) in a subgroup of indian patients with type 2 diabetes ( t2d ) switched from either insulin glargine ( iglar ) or neutral protamine hagedorn ( nph ) insulin in the 24-week , non - interventional a1chieve study.materials and methods : indian patients with t2d switching from pre - study iglaror nph insulin to idet were included . 
 safety and effectiveness outcomes were evaluated by the physicians in local clinical settings.results:a total of 102 patients switched from iglar to idet ( gla group ) and 39 patients switched from nph insulin to idet ( neu group ) . at baseline , 
 the mean glycated hemoglobin a1c ( hba1c ) levels were 9.9  1.8% in the gla group and 9.1  1.2% in the neu group . 
 no serious adverse drug reactions , serious adverse events , or major hypoglycemic events were reported in either group throughout the study . at baseline and week 24 , 11.8% and 7.5% of patients , respectively , reported overall hypoglycemic events in the gla group . 
 no hypoglycemic events were reported at week 24 in the neu group . at week 24 , the mean hba1c levels were 7.6  0.9% in the gla group and 7.3  0.7% in the neu group . 
 the mean fasting plasma glucose , postprandial plasma glucose and quality of life also appeared to improve over 24 weeks.conclusion:switching to idet therapy from iglar and nph insulin was well - tolerated and appeared to be associated with improved glycogenic control in indian patients .
