Abstract

Insulin icodec is a long-acting basal insulin analog under development that can be administered once weekly. The main purpose of this article is to provide an appraisal on insulin icodec based on available data published in a series of phase 3 clinical trials collectively called the ONWARDS Program. In 3 of the 4 published ONWARDS trials, reductions in glycated hemoglobin (HbA1c) levels were slightly superior with insulin icodec compared with once-daily insulin glargine or degludec with a difference of approximately 0.2 percentage points. In the 4th trial, insulin icodec was not inferior to degludec in decreasing HbA1c values. Data analysis of continuous glucose monitoring (CGM) showed greater or similar time spent in range (TIR) with insulin icodec versus insulin glargine or degludec. Incidence of level 1 hypoglycemia [blood glucose (BG) levels 54-69 mg/dl] was higher with insulin icodec compared with insulin glargine or degludec with estimated rate ratio (ERR) ranging from 1.25 to 1.88. Incidence of combined level 2 hypoglycemia (clinically significant hypoglycemia with BG < 54 mg/dl) and level 3 hypoglycemia (severe hypoglycemia with cognitive impairment requiring external assistance) was approximately 2-3 times higher with insulin icodec versus insulin glargine or degludec.  Preliminary data in patients with type 1 diabetes showed approximately doubling rates of combined level 2 or 3 hypoglycemia with insulin icodec [(19.9 hypoglycemic events per person-year-exposure (PYE)] versus insulin degludec (10.3 hypoglycemic events per PYE).  Time spent below range (TBR) in CGM was similar between insulin icodec and insulin glargine or degludec. Weight gain was generally similar with use of insulin icodec and insulin glargine or degludec. Yet, in one trial, weight gain was significantly greater with insulin icodec versus degludec, with an estimated treatment difference (ETD) of 1.7 kg. Allergic reactions were not increased with use of insulin icodec compared with glargine or degludec. In conclusion, insulin icodec may be a convenient basal insulin that is administered once weekly. It is at least as effective as insulin glargine or degludec. Yet, it is associated with increased incidence of all levels of hypoglycemia. 

Introduction

The once-weekly insulin icodec was engineered in an attempt to improve adherence to basal insulin intake. The half-life of insulin icodec is 196 hours (8.1 days) making it suitable for once-weekly administration [1]. Insulin icodec reaches a steady state after 3-4 weeks, then exhibits an evenly distributed glucose-lowering activity throughout the week [1]. The long duration of action of insulin icodec is attributed to 2 main factors. First, binding to albumin through addition of a C20 fatty acid-containing side chain to form an albumin-binding depot from which icodec is slowly released in the circulation. Second, 3 amino acid substitutions that decreases affinity of icodec to insulin receptors leading to its decreased rate of clearance. Normally, insulin clearance occurs primarily through internalization following binding of insulin to its receptors at cell surface. Thus, reduced binding of insulin icodec to insulin receptors will lead to its reduced clearance and further prolongation of its action [1]. Importantly, the reduced affinity of icodec to insulin receptor does not compromise its potency but slows its action [1]. The concentration of formulation of insulin icodec is 7 times higher than that of the standard insulin U100 formulation. It follows that the volume of insulin icodec administered once weekly is similar to other basal insulin dosing volumes given once daily [1]. To support its approval, insulin icodec is being evaluated in a program called ONWARDS. The latter consists of 6 phase 3 clinical trials [2]. The idea of this program is to assess efficacy and safety of insulin icodec in different clinical situations in patients with diabetes. Four of these 6 trials have been recently published and summarized in table 1 [3-6]. The main objective of this article is to review the advantages and limitations of insulin icodec based on results of the ONWARDS program.

Overview of the ONWARDS trials

There are several common features in trials of the ONWARD Program. All included studies were randomized, multinational and treat-to target phase 3a clinical trials [3-6]. All trials were open-label except ONWARDS 3 trial, which was double masked [5].  The primary endpoint was the change in HbA1c levels from baseline to the end of the study. The target of fasting self-measured BG was 80-130 mg/dl. To achieve that target, doses of insulin icodec, glargine and degludec were adjusted weekly based on 3 pre-breakfast BG readings (measured on 2 days prior to and on the day of the weekly titration [3]. Thus, if the mean of the 3 BG values are > 130 mg/dl, insulin icodec dose is increased by 20 units weekly and doses of glargine or degludec are increased by 3 units daily. On the other hand, if the lowest of the 3 fasting BG values is < 80 n=984)>

Effects of insulin icodec on glycemic control

In ONWARDS 1, 2, and 3, insulin icodec was shown to be slightly but statistically superior to both glargine glargine and degludec in lowering HbA1c levels, with estimated treatment difference (ETD) of approximately 0.2 percentage points (table 1) [3-5]. In ONWARDS 4, insulin icodec was non-inferior to insulin degludec (table 1) [6].  In the 4 trials, the mean reduction in HbA1c levels by insulin icodec was approximately 1.5 percentage points compared with baseline [3-6]. Inspection of time curves of HbA1c values of insulin icodec revealed that reductions in HbA1c values were evident 10 weeks following its initiation, then reached a trough at week 26 followed by a plateau [3-6]. Similar trajectory was observed with insulin glargine and degludec [3-6]. Data from CGM was used for a duration of 4 weeks in ONWARDS 1 and 2 trials to identify the diurnal pattern of BG [3,4]. Overall, no significant differences in time spent in range (70-180 mg/dl) was identified between icodec groups and glargine or degludec groups [3,4]. Yet, in ONWARDS 1 trial, the percentage of time spent with BG levels above the range (ie. > 180 mg/dl) was approximately 1 hour less with insulin icodec than with insulin glargine [3].

Patient satisfaction with insulin icodec 

Patient satisfaction with insulin icodec versus degludec was evaluated in ONWARDS 2 trial using the “Diabetes Treatment Satisfaction Questionnaire” (DTSQ) with higher score indicating greater satisfaction [4]. At week 26, the DTSQ was slightly but significantly higher in patients randomized to insulin icodec 4.22 versus insulin degludec 2.96, ETD 1.25 (95% CI, 0.41 to 2.10, P=0.003) (table 1) [4].

Safety of insulin icodec

Hypoglycemia

Given the long duration of action of insulin icodec, there is a major concern about increased risk of prolonged hypoglycemia, slow recovery and recurrence of hypoglycemic episodes. In a short-term (7 weeks) cross-over trial including selected patients with type 2 diabetes (n=43, mean age 56 years) without co-morbidities, Pieber et al [7] compared the frequency and severity of hypoglycemia in patients randomized to insulin icodec versus glargine. These authors induced hypoglycemia to a target plasma glucose levels of 54 mg/dl by doubling and tripling the doses of insulin icodec and glargine. Overall, they observed no significant differences between insulin icodec and glargine in the proportions of patients who developed hypoglycemia, hypoglycemic symptoms, time to recovery, and in the extent of rise in insulin counterregulatory hormones in response to hypoglycemia [7]. Despite these preliminary reassuring findings, results of clinical trials including higher number of patients who were followed for longer duration clearly showed increased risk of hypoglycemia with insulin icodec versus either insulin glargine or degludec.   Thus, in ONWARDS 1 trial, at week 83, the rates of combined clinically significant (level 2) or severe hypoglycemia (level 3) were significantly greater with insulin icodec compared with glargine, 0.30 and 0.16 hypoglycemic events per PYE, respectively, ERR 1.63 (95% CI, 1.02 to 2.61) [3]. Furthermore, the difference in these rates between insulin icodec and glargine widened with duration of use [3]. Interestingly, the increased rates of hypoglycemia associated with use of insulin icodec was largely attributed to 3 patients who experienced 105 clinically significant hypoglycemic episodes [3]. Unfortunately, the authors did not mention any possible causes for clustering and recurrent hypoglycemia in these 3 patients such as kidney dysfunction, intermittent sickness with decreased oral intake, medications errors, use of a sulfonylurea, etc) [3]. Rates of level 1 hypoglycemic events were also higher with insulin icodec versus glargine in ONWRDS 1 trial, 3.02 events per PYE versus 1.39 events per PEY at 83 weeks [3]. In ONWARDS 3 trial, combined level 2 and 3 hypoglycemia from baseline to week 26 was approximately 3-fold higher with insulin icodec versus degludec; ERR 3.012 (95% 1.30 to 7.51, P=0.01) [5]. Furthermore, increased risk of hypoglycemia (level 1, and combined level 2 and 3) with insulin icodec was observed compared with insulin degludec in ONWARS 2 and 3 trials (table 1) [4,5]. As mentioned earlier, ONWARDS 4 trial was the only study that compared insulin icodec with insulin glargine on a background of pre-meal bolus insulin aspart [6]. Again, the latter trial showed increased risk of level 1 hypoglycemia with insulin icodec versus glargine, ERR 1.25 (95% CI, 1.03 to 1.52) P=0.025 (table 1) [6]. In ONWARDS 4 study, combined level 2 and 3 hypoglycemia as well as nocturnal hypoglycemia were not increased in the insulin icodec group compared with the insulin glargine group. However, there was numerical increase in event rate of level 3 hypoglycemia in the insulin icodec group versus glargine group, 0.04 event per PYE vs 0.02 event per PYE, ERR 2.19, 95% CI 0.2 to 24.4, P=0.53) [6]. In type 1 diabetes, preliminary results of ONWARDS 6 trial showed that rates of level 2 and 3 hypoglycemia with insulin icodec were approximately double the rates with degludec at 26 weeks, 19.9 versus 10.3 events per person-year [8]. Meanwhile, the use of CGM for 4 weeks during the ONWARDS 1 and 2 trials revealed similar time spent under BG levels of 54 mg/dl in patients receiving insulin icodec versus glargine or degludec [3,4]. 

Weight gain

There was a trend towards more weight gain associated with use of insulin icodec versus glargine or degludec in ONWARDS 1, 3, and 4 trials (table 1). In ONWARDS 2 trial, patients randomized to insulin icodec had a mean weight gain of 1.4 kg, whereas those randomized to insulin degludec had 0.3 kg weight loss, ETD 1.7 kg (95% CI, 0.76 to 2.63, P=0.0004) (table 1) [4]. 

Advantages of insulin icodec

The major advantage of insulin icodec is the convenience and simplicity of administration once weekly avoiding 6 extra injections per week compared with traditional basal insulins. In addition, if necessary, the day of administration may be changed by up to 3 days ensuring a minimum of 4 days between injections [6]. Moreover, a single dose-study showed that pharmacokinetics and pharmacodynamics of icodec did not change significantly whether injected in the thigh, abdomen or upper arm [9]. In terms of efficacy, insulin icodec proved to be at least as effective, if not slightly more effective, as once-daily insulin glargine and degludec in patients with long duration of type 2 diabetes. However, the mean difference in HbA1c levels of 0.2 percentage points between insulin icodec and glargine or degludec is unlikely to have any major clinical significance. It also reassuring that available evidence do not suggest that insulin icodec is more immunogenic than other basal insulins as reflected by the low number of allergic and injection site reactions that were generally similar to insulin glargine and degludec [3-6]. 

Limitations of insulin icodec

The main limitation of insulin icodec is the increased incidence of all levels of hypoglycemia as detailed above. When expressed in absolute terms, this high risk of hypoglycemia can be substantial as illustrated by the difference in rates of combined level 2 and 3 hypoglycemia in patients with type 1 diabetes between insulin icodec and insulin degludec, 19.9 events per PYE and 10.4 events per PYE, respectively [8]. In fact, in the latter study, the absolute difference in hypoglycemic episodes between insulin icodec and degludec is sufficiently high to question the safety of use of insulin icodec in patients with type 1 diabetes. Unfortunately, insulin icodec was not studied in patients with end-stage kidney disease and those with baseline HbA1c levels > 11.0

Conclusions and current needs

Insulin icodec represents a new class of long-acting basal insulin analogs that can be administered once weekly. Available evidence suggest insulin icodec may have similar or slightly higher efficacy than once-daily insulin glargine or degludec. However, the use of insulin icodec is associated with increased risk of hypoglycemia. The latter may be due to its prolonged duration of action and possibly aggressive dose titration. In fact, the titration schedule of the ONWARDS trials was based on an earlier study by Lingvay et al [10]. This study showed that insulin icodec dose adjustment by ±20 units weekly to attain the fasting BG target of 80-130 mg/dl achieved the best balance between efficacy and hypoglycemia compared with 2 other more aggressive titration regimens [10]. It is possible that less aggressive titration of insulin icodec might result in less frequency of hypoglycemia, e.g. an increase of its dose by 10 units per week instead of 20 units.  The combination of once-weekly icodec with once weekly glucagon-like peptide-1 receptor agonist (GLP-1 RA) in one single formulation may be an attractive treatment strategy that potentially lowers icodec doses and therefore incidence of hypoglycemia. In addition, the weight loss-inducing effect of the GLP-1 may help attenuate or even override the weight gain induced by insulin icodec. In fact, multiple phase 3 clinical trials are underway to compare the combination of insulin icodec with semaglutide (called icosema) with each component alone and with glargine in patients with type 2 diabetes [11-13].  Although data derived from the ONWARDS trials was useful in demonstrating the short-term efficacy and safety profile of insulin icodec, well-designed studies are needed to establish its long-term efficacy and safety.
