Who are we ?


ALTEXA Development, a consultancy company established in Monaco in 2008, provides expert services for pharmaceutical, medical device, biotech and cosmeceuticals companies to assist in the pre-clinical development of compounds (drugs, raw materials and finished products), focussing on the use of 3D human tissue models. In addition, we offer similar services for the veterinary market using 3D animal tissue models (canine, rodent).

ALTEXA Development strongly advocates the use of (advanced) 3D tissue models for pre-clinical research, as opposed to monolayer cell-based assays, as they provide more relevant data that correlate much better with human clinical responses.
