The purpose of this study is to evaluate the combined remission of complex perianal fistulas, defined as the clinical assessment at Week 24 of closure of all treated external openings that were draining at baseline despite gentle finger compression, and absence of collections greater than (>) 2 centimeter (cm) (in at least 2 dimensions) confirmed by blinded central magnetic resonance imaging (MRI) assessment at Week 24.

The purpose of this randomised, multicentre, double-blind, placebo-controlled, phase Ib/IIa study is to assess the safety, tolerability and efficacy of eASCs (Cx611) administered intravenously as adjunctive therapy, therefore in addition to standard of care (SoC) therapy, to patients with severe community-acquired bacterial pneumonia (sCABP).
The completion of this study will contribute to the basic knowledge on stem cells and their mode-of-action, and has a large translational character, i.e. to document the safety and explore the efficacy of Cx611 in patients with sCABP.

Phase I, randomized, parallel group, placebo control, unicentric, interventional study. Thirty two healthy male volunteers aged between 18-35 years will be randomized into the eASCs or placebo group if they meet all the inclusion criteria at a 3:1 ratio.
The treatment administration will be infused intravenously to the following groups after randomization:
First arm: 250,000 cells/kg
Second arm: 1 million cells/kg
Third arm: 4 million cells/kg
Fourth arm: placebo according to their weight.
An hour after the end of the eASCs administration, all subjects will be given an intravenous dose of LPS. Subjects will be allowed to leave in the evening once deemed clinically stable by the investigator.
