Translational Challenges in Preclinical Research

Despite major progress in biology and technology, preclinical research still struggles to predict what will happen in humans. This affects development time, cost, and clinical success.

90%

Clinical Failure Rate

Most drug candidates that perform well in preclinical models fail in human trials, showing clear limits in current models.

$2.6B

Average cost per approved drug

Late-stage failures caused by poor early prediction significantly increase R&D costs and financial risk.

10-15

Years from lab to market

Long development timelines delay patient access and increase scientific and business risk.

Our Approach

To address this problem, Asemblis is developing a new in vitro modelling concept based on a simple idea: increase biological relevance without increasing operational complexity. Our approach is shaped by real needs and constraints observed in R&D labs and aims to combine bioengineering and fluidics to provide:

Human Relevance

Bioengineered tissue models designed to reflect key human biological interactions needed for disease research and drug testing.

Operational Simplicity

A design approach that avoids complex or expensive equipment, supporting easy integration into existing laboratory workflows.

3Rs alignment

An integrative framework that supports New Approach Methodologies (NAMs), in line with the FDA Modernization Act 2.0.

De-risk Early

The goal is to generate more informative preclinical data earlier, helping teams make clearer go / no-go decisions.

*Our solution is currently in early development and is being advanced in collaboration with the Zurich University of Applied Sciences (ZHAW). At this stage, we are actively engaging with industry partners to define relevant biological readouts/endpoints and to explore feasibility studies and pilot projects.
