Aim: To evaluate the equivalence of immunogenicity, safety and efficacy of Gan & Lee (GL) Glargine (Basalin®; Gan & Lee Pharmaceutical) with that of the reference product (Lantus®) in adult participants with type 2 diabetes mellitus.

Methods: This was a phase 3, multicenter, open-label, equivalence trial conducted across 57 sites. In total, 567 participants with type 2 diabetes mellitus were randomized in a 1:1 ratio to undergo treatment with either GL Glargine or Lantus® for 26 weeks.

Importance: The effects of tirzepatide, a dual glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 receptor agonist, as an addition to insulin glargine for treatment of type 2 diabetes have not been described.

Objective: To assess the efficacy and safety of tirzepatide added to insulin glargine in patients with type 2 diabetes with inadequate glycemic control.

Design, Setting, And Participants: Randomized phase 3 clinical trial conducted at 45 medical research centers and hospitals in 8 countries (enrollment from August 30, 2019, to March 20, 2020; follow-up completed January 13, 2021) in 475 adults with type 2 diabetes and inadequate glycemic control while treated with once-daily insulin glargine with or without metformin.

Ultra rapid lispro (URLi) is a new insulin lispro formulation that has accelerated absorption and improved postprandial glucose control compared with insulin lispro (Humalog). The compatibility and safety of URLi versus lispro were evaluated in patients with type 1 diabetes using continuous subcutaneous insulin infusion (insulin pump). In this phase 3, double-blind, crossover study, 49 patients were randomized to two 6-week treatment periods, after a 2-week lead-in period on lispro.

Context: Combination therapy with insulin and glucagon-like peptide-1 receptor agonists (GLP-1RAs) is important for treating type 2 diabetes (T2D). This trial assesses the efficacy and safety of semaglutide, a GLP-1RA, as an add-on to basal insulin.

Objective: To demonstrate the superiority of semaglutide vs placebo on glycemic control as an add-on to basal insulin in patients with T2D.

Importance: Hypoglycemia, a serious risk for insulin-treated patients with type 2 diabetes, negatively affects glycemic control.

Objective: To test whether treatment with basal insulin degludec is associated with a lower rate of hypoglycemia compared with insulin glargine U100 in patients with type 2 diabetes.

Design, Setting, And Participants: Randomized, double-blind, treat-to-target crossover trial including two 32-week treatment periods, each with a 16-week titration period and a 16-week maintenance period.

Many patients with type 2 diabetes require high basal insulin doses, necessitating multiple injections, increasing patient burden, and resulting in reduced treatment adherence. This randomized, controlled, crossover trial compared the efficacy, safety, and patient-reported outcomes for a concentrated formulation of insulin degludec (200 units/mL) to those of insulin glargine in patients requiring high doses of basal insulin. By offering equivalent glycemic control while reducing the rate of confirmed hypoglycemia and the number of injections required for administration, insulin degludec 200 units/mL may be preferred by patients with type 2 diabetes who require high basal insulin doses.

Aims: To re-analyse, using a series of alternative hypoglycaemia definitions, the data from 2 trials, DUAL I and V, in which the once-daily, fixed ratio combination of insulin degludec/liraglutide (IDegLira) was compared with basal insulin therapy.

Material And Methods: Post hoc analyses of the DUAL I (patients uncontrolled on oral antidiabetic drugs) and DUAL V (patients uncontrolled on insulin glargine (IGlar) U100) trials were carried out using different definitions of hypoglycaemia and according to whether treatments were administered in the morning or afternoon. Rates of hypoglycaemia for the definitions of confirmed and American Diabetes Association (ADA)-documented symptomatic hypoglycaemia were compared according to age, gender and body mass index (BMI).

Aim: To compare the addition of weekly dulaglutide vs the addition of placebo to titrated glargine in patients with type 2 diabetes (T2D) with sub-optimum glycated haemoglobin (HbA1c) concentration.

Materials And Methods: Patients (N = 300) from this phase III, double-blind, parallel-arm, placebo-controlled study were randomized to weekly subcutaneous injections of dulaglutide 1.5 mg or placebo with titrated daily glargine (mean ± standard deviation baseline dose: 39 ± 22 U), with or without metformin (≥1500 mg/d).

Importance: Achieving glycemic control remains a challenge for patients with type 2 diabetes, even with insulin therapy.

Objective: To assess whether a fixed ratio of insulin degludec/liraglutide was noninferior to continued titration of insulin glargine in patients with uncontrolled type 2 diabetes treated with insulin glargine and metformin.

Design, Setting, And Participants: Phase 3, multinational, multicenter, 26-week, randomized, open-label, 2-group, treat-to-target trial conducted at 75 centers in 10 countries from September 2013 to November 2014 among 557 patients with uncontrolled diabetes treated with glargine (20-50 U) and metformin (≥1500 mg/d) with glycated hemoglobin (HbA1c) levels of 7% to 10% and a body mass index of 40 or lower.

Introduction: Little is known about the effect of body mass index (BMI) on the efficacy and safety of testosterone therapy in hypogonadal men. A prior noncomparative trial demonstrated that testosterone 2% gel restored testosterone levels in hypogonadal men and was generally well tolerated.

Aim: This post hoc analysis evaluated the influence of BMI on the pharmacokinetics of testosterone therapy in men with low testosterone.

Background: Patients with type 2 diabetes mellitus are routinely treated with combinations of glucose-lowering agents. The adverse event (AE) profile and effects on glycemic control have not been assessed for the glucagon-like peptide-1 receptor agonist exenatide once weekly in combination with a thiazolidinedione (TZD) with or without metformin.

Objective: This study was conducted to examine the long-term safety profile and changes in glycemic control and weight for exenatide once weekly with TZD with or without metformin in patients with type 2 diabetes mellitus over 2 years.

Testosterone replacement therapy (TRT) can improve the symptoms, signs, and well being of hypogonadal men by restoring serum testosterone concentrations to physiologic levels. This multicenter, open-label noncomparative trial of men with hypogonadism evaluated the pharmacokinetic profile and safety of a novel testosterone 2% gel (Fortesta™ Gel), administered once daily to the front and inner thighs at starting doses of 40 mg/d. The metered-dose delivery system allowed dose adjustments in 10-mg increments between 10 and 70 mg/d.

There is a Type 2 diabetes epidemic; however, unfortunately, even though insulin is an effective therapy, it is mostly used late and as a last resort. Type 1 diabetics find it difficult to administer extra insulin injections when needed owing to the inconvenience and, although most cope well, many dislike injecting themselves so frequently. The newly approved EXUBERA inhaled insulin should help counteract the resistance of patients and physicians in instituting insulin in the Type 2 diabetic, and the Type 1 diabetic can take more than 1000 fewer injections per year, making their diabetes easier to live with.

Objective: Previous studies with inhaled human insulin [Exubera (EXU); insulin human (recombinant DNA origin) Inhalation Powder, Pfizer Inc., New York, NY; Nektar Therapeutics, San Carlos, CA) show comparable efficacy to sc insulin and small declines in pulmonary function in type 1 and 2 diabetes. This is a detailed characterization of short-term efficacy and pulmonary safety profile of EXU.

Objective: We sought to evaluate the effects of muraglitazar, a dual (alpha/gamma) peroxisome proliferator-activated receptor (PPAR) activator within the new glitazar class, on hyperglycemia and lipid abnormalities.

Research Design And Methods: A double-blind, randomized, controlled trial was performed in 1,159 patients with type 2 diabetes inadequately controlled with metformin. Patients received once-daily doses of either 5 mg muraglitazar or 30 mg pioglitazone for a total of 24 weeks in addition to open-label metformin.
