Number of Participants With an HbA1c Reduction From Baseline of ≥0.50% (Absolute Difference) Without Episodes of Severe Hypoglycemia [1] | ||||||||||||
End point description |
The primary endpoint was defined as the proportion of participant with an HbA1c reduction from baseline of ≥0.50% (absolute difference) without episodes of severe hypoglycemia at Week 27/28 (Visit 4). No efficacy evaluation was conducted due to the low recruitment rate (out of the 24 participants screened, only 2 participants were enrolled, 1 in the ladarixin group and 1 in the placebo group), resulting in a sample size not adequate for any formal statistical analyses. The low recruitment rate led the Sponsor decide to close enrollment on 04th August 2023 and thus to early terminate the study. No participants experienced an HbA1c reduction from baseline of at least ≥0.50%

Number of participants With Treatment Emergent Adverse Events (TEAEs) of Any Kind From the Beginning of Study Treatment to up to the End of Study Participation | ||||||||||||
End point description |
This secondary endpoint was defined as the number of participants experiencing treatment emergent adverse events (TEAEs) of any kind from the beginning of study treatment administration to the end of study participation. An adverse event (AE) is any untoward medical occurrence after exposure to a medicine, which is not necessarily caused by that medicine. A serious AE (SAE) was any adverse event that results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in persistent or significant disability or incapacity, or is a birth defect. A non serious AE (nSAE) is any adverse drug experience associated with the use of the Product in humans, whether or not considered drug-related, which is not a SAE. TEAEs were defined as events with onset date or worsening during the on-treatment period.
