The efficacy and safety of GP40081 (insulin aspart biphasic 30) compared with NovoMix® 30 in Type 2 diabetes patients.

Aim: To evaluate the safety and efficacy of insulin Aspart-Mix biosimilar candidate GP40081 (GP-Asp30) compared with NovoMix® 30 (NN-Asp30). Materials & methods: In a randomized open-label, active-controlled, 26-week non-inferiority clinical trial 264 patients with Type 2 diabetes mellitus were randomized 1:1 to receive once-daily GP-Asp30 or NN-Asp30. The primary safety end point was the immune response rate. Efficacy outcomes were a mean change in HbA1c (primary), frequency of achieving a glycemic g fasting plasma glucose levels, 7-point glucose profiles, and insulin doses. Results: The immune response developed in 10/126 (8%) participants in the GP-Asp30 group and in 10/125 (8%) participants in the NN-Asp30 group (p = 1.000). The mean difference in HbA1c change between groups was 0.12 (95%CI [-0.14, 0.38]). Other secondary efficacy and safety outcomes weren't statistically different between the two groups. Conclusion: GP-Asp30 demonstrated similar safety and efficacy compared with NN-Asp30 and may be considered a biosimilar insulin.

Clinical Pharmacology of Insulin Aspart Biosimilar GP40071: Pharmacokinetic/Pharmacodynamic Comparability in Hyperinsulinemic Euglycemic Clamp Procedure.

Insulin aspart is a short-acting insulin analogue that is used to control postprandial glycemia levels in diabetic patients. The aim of this clinical trial was to compare the pharmacokinetics and pharmacodynamics of GP40071 (GP-Asp) and NovoRapid Penfill (Novo-Asp) in a hyperinsulinemic euglycemic clamp (HEC). This trial was conducted as a part of a GP40071 biosimilar clinical development program. This was a phase I randomized, double-blind, two-period crossover study. Twenty-six healthy male volunteers aged 18 to 45 years who met the inclusion criteria underwent the procedure of an HEC following a single subcutaneous injection of 0.3 IU/kg of either GP-Asp or Novo-Asp into the abdomen. After doses, plasma glucose levels were monitored every 5 minutes for 8 hours. The adjustment of the glucose infusion rate (GIR) was based on the blood glucose measurements. The GIR values were used to evaluate the PD profiles of the studied drugs. Regular blood sampling was performed during the study to obtain sufficient pharmacokinetic data. The 90% confidence intervals for the geometric mean ratios of the pharmacokinetic (AUCins.0-t , Cins.max ) and pharmacodynamic (GIRmax , AUCGIR0-t ) parameters of GP-Asp were within the 80%-125% comparability limits. The safety profiles of the drugs were also comparable. Bioequivalence, similar PD, and safety of GP-Asp and Novo-Asp were demonstrated.

Low 25(OH)D Level Is Associated with Severe Course and Poor Prognosis in COVID-19.

We evaluated associations between serum 25-hydroxyvitamin D [25(OH)D] level and severity of new coronavirus infection (COVID-19) in hospitalized patients. We assessed serum 25(OH)D level in 133 patients aged 21-93 years. Twenty-five (19%) patients had severe disease, 108 patients (81%) had moderate disease, and 18 (14%) patients died. 25(OH)D level ranged from 3.0 to 97.0 ng/mL (median, 13.5 [25%; 75%, 9.6; 23.3] ng/mL). Vitamin D deficiency was diagnosed in 90 patients, including 37 with severe deficiency. In patients with severe course of disease, 25(OH)D level was lower (median, 9.7 [25%; 75%, 6.0; 14.9] ng/mL), and vitamin D deficiency was more common than in patients with moderate course (median, 14.6 [25%; 75%, 10.6; 24.4] ng/mL, p = 0.003). In patients who died, 25(OH)D was 9.6 [25%; 75%, 6.0; 11.5] ng/mL, compared with 14.8 [25%; 75%, 10.1; 24.3] ng/mL in discharged patients (p = 0.001). Severe vitamin D deficiency was associated with increased risk of COVID-19 severity and fatal outcome. The threshold for 25(OH)D level associated with increased risk of severe course was 11.7 ng/mL. Approximately the same 25(OH)D level, 10.9 ng/mL, was associated with increased risk of mortality. Thus, most COVID-19 patients have vitamin D deficiency; severe vitamin D deficiency is associated with increased risk of COVID-19 severity and fatal outcome.
