The primary objective of this exploratory meta-analysis is to evaluate the frequencies, incidence rates, and hazard ratios of lower-limb amputation (LLA) events (primary outcome) and of adverse events related to amputation (secondary outcome) in patients treated with empagliflozin compared with placebo in the pooled population of the long-term studies 1245.25, 1245.110, and 1245.121 (SAF-M1), in the pooled population of studies 1245.110 and 1245.121 (SAFM2), and in each of the 3 studies separately.

Primary | Incidence Rate of Lower Limb Amputation (LLA) | Incidence rate of lower limb amputation (LLA). Incidence rate were provided as rate per 100 patients-years (pt-yrs) calculated as the observed number of patients with event divided by observed time-at-risk over all patients. Time at risk was derived as followed: Patient with event: time at risk in days = date of start of first event - treatment start date + 1. Patients without event: time at risk in days = last date on treatment + 7 days - treatment start date + 1. Abbreviation: pt-yrs = patient-years. |
From first to last dose of study medication plus 7 days to account for the residual drug effect, up to 1639 days. | |
Secondary | Incidence Rate of Adverse Events Related to Amputation | Incidence rate of adverse events (AEs) related to amputation. Incidence rate were provided as rate per 100 patients-years (pt-yrs) calculated as the observed number of patients with event divided by observed time-at-risk over all patients. Time at risk was derived as followed: Patient with event: time at risk in days = date of start of first event - treatment start date + 1. Patients without event: time at risk in days = last date on treatment + 7 days - treatment start date + 1. A search with a pre-defined list of MedDRA preferred terms was performed to identify all AEs related to amputation. These AE included vascular disorders, diabetic-foot-related events, wound/infections, nervous system disorders and volume depletion events. Abbreviation: pt-yrs = patient-years. |
From first to last dose of study medication plus 7 days to account for the residual drug effect, up to 1639 days. |
