NCT04937816

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • 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 Outcomes (1)

  • Incidence Rate of Adverse Events Related to Amputation

    From first to last dose of study medication plus 7 days to account for the residual drug effect, up to 1639 days.

Limitations and Caveats

For study NCT01131676, events leading to LLA were not prespecified but were identified during unblinded medical review of data. Also, since both empagliflozin arms (10 and 25 mg) of study NCT01131676 were combined for the pooled SAF-M1 analysis, this led not only to a different sample size, but also to different patient populations for placebo and empagliflozin, respectively.

Data Sharing

IPD Sharing
Will not share

Clinical studies sponsored by Boehringer Ingelheim, phases I to IV, interventional and non-interventional, are in scope for sharing of the raw clinical study data and clinical study documents. Exceptions might apply, e.g. studies in products where Boehringer Ingelheim is not the license holder; studies regarding pharmaceutical formulations and associated analytical methods, and studies pertinent to pharmacokinetics using human biomaterials; studies conducted in a single center or targeting rare diseases (in case of low number of patients and therefore limitations with anonymization).
