The M1Pram is an injectable aqueous composition containing 3.45 mg/mL (100 U/mL) of human insulin A21G, 0.6 mg/mL of pramlintide and 18 mM of acetate buffer at pH 4.
This composition can be obtained by analogous process than those disclosed in WO2019020820A2.
A phase 2 clinical trial was conducted to confirm the efficacy and safety of M1Pram in subjects with type 1 diabetes (NCT04816890).
The M1Pram is intended to be injected by the subcutaneous route. In such a formulation, Human insulin A21G shows the pharmacokinetic and pharmacodynamic characteristics of a rapid-acting mealtime insulin, not those of a basal insulin.
The primary objective of the trial was to compare the efficacy of prandial use of M1Pram to Humalog® (insulin lispro) on body weight change after 16 weeks of optimised titration, in combination with a basal insulin.
In addition, exploratory objectives included the comparison of the efficacy of prandial use of M1Pram with Humalog® in subgroups of subjects with a body mass index (BMI) and HbA1c above and below the median at screening.
A post-hoc analysis also included the comparison of the efficacy of prandial use of M1Pram with Humalog® in subgroups of subjects with a body mass index (BMI)>=30 kg/m2.
The primary endpoint was the body weight change from baseline to week 16 of treatment.
In addition, exploratory endpoints included analysis of the subgroups of the primary endpoint according to BMI and HbA1c below and above the median.
A post-hoc analysis was also performed to analyze the subgroups of the primary endpoint according to BMI>=30 kg/m2.
This was a multicentric, open-label, randomized, two-arm parallel, active-comparator controlled phase 2 clinical trial evaluating the efficacy and safety of M1Pram in subjects with type 1 diabetes.
Key inclusion criteria included subjects
80 patients were randomized 1:1 to M1Pram or Humalog®.
The trial consisted in 4 periods:
The trial design is shown in
37 subjects completed the trial in the Humalog® arm and 34 in the M1 Pram arm. The body weight change after 16 weeks of treatment for all completers and for subgroups are presented in the table 1. The subgroups were selected depending on the patients' metrics at screening.
The results indicate that the patients with a higher BMI (above 28 kg/m2 or above or equal to 30 kg/m2) benefited more from the M1 Pram treatment in terms of body weight control than the whole population of patients above 25 kg/m2.
Similarly, patients that had a worse glycemic control (HbA1c >7.6%) benefited more from the treatment in terms of body weight control.
