  • Patient population benefitting most from enibarcimab treatment in septic shock can clearly be defined by two biomarkers, as shown by data presented today

  • In the AdrenOSS-2 trial, the respective patient subgroup had a statistically significant >60% relative reduction in 28-day mortality vs. placebo. Adrenomed is preparing a confirmatory trial

  • Enibarcimab is targeting loss of vascular integrity, a previously unaddressed pathophysiological mechanism1

HENNIGSDORF, Germany and BERLIN, Sept. 08, 2023 (GLOBE NEWSWIRE) -- Adrenomed AG, the vascular integrity company, today announced new findings on the biomarker-guided treatment of septic shock with enibarcimab. New data analyses of the phase II clinical trial AdrenOSS-2 validate the precision medicine approach applied by Adrenomed in the development of its non-neutralizing antibody enibarcimab for the treatment of septic shock. It shows that the patient population benefitting most from enibarcimab can clearly be identified by the biomarkers Adrenomedullin (ADM) with elevated levels, and low levels of circulating dipeptidyl peptidase 3 (cDPP3).

During the 11th Weimar Sepsis Update3, the data were presented in a scientific talk4 given today by Prof. Matthijs Kox, Department of Intensive Care Medicine, Radboud University Medical Centre, Nijmegen, The Netherlands, and in a poster presentation5 from the working group of critical care physician Prof. Peter Pickkers, Nijmegen.

In preparation of a confirmatory clinical trial, the double-blind, randomized, placebo-controlled, biomarker-guided phase II trial AdrenOSS-2 (n = 301) included a prespecified analysis of the role of cDPP3 as a second biomarker (next to ADM) to exclude patients who are unlikely to respond to enibarcimab treatment. DPP3 is a cytosolic enzyme involved in the degradation of various cardiovascular and endorphin mediators. High levels of circulating DPP3 (cDPP3) indicate a high risk of organ dysfunction and mortality.6 This pathway is mechanistically independent from the loss of vascular integrity, which is known to be the main driver of mortality in septic shock and is indicated by elevated plasma levels of ADM (>70 pg/mL). Consequently, the aim of additional analyses was to investigate the impact of different cDPP3 levels on the treatment effect (28-day all-cause mortality) and to identify a suitable cut-off level. It was shown that the effect of enibarcimab on mortality improves with lower cDPP3 values and that the patients with elevated ADM, but non-elevated baseline cDPP3 (below the upper normal range, ≤ 30-50 ng/mL), benefitted the most from enibarcimab treatment.7 At 28 days, this patient subgroup had a statistically significant >60% relative reduction in mortality compared to placebo.8
