Multi-centre, open label, multiple ascending dose trial in patients with type 1 diabetes mellitus
This is a Phase 1, open-label, multiple dose trial with two parts in patients with type 1 diabetes mellitus (T1DM). Part 1 consists of four cohorts with multiple ascending doses of insulin Tregopil and comprises a sentinel dosing design. Part 2 consists of a randomised, 2-treatment, crossover design with mixed meal tests (MMTs) of different compositions followed by parallel design titrated treatment period. Both parts include dosing during an in-house period and during a subsequent outpatient period.

Insulin Tregopil is recombinant human insulin modified by a single amphiphilic oligomer covalently linked via an amide bond to lysine at position 29 of the B-chain. This alters the physicochemical characteristics of the molecule, leading to enhanced stability and resistance to intestinal degradation following oral administration.
