First-in-human may be further away than you think
Teams that believe they are ready for first-in-human can still be 12 to 18 months away. The gap is rarely in the science. Formulation, manufacturing, stability work or the toxicology package may not yet support the clinical design. Clarenta identifies these gaps early and helps you build a practical path towards first-in-human.

Strengthen your biotech programme at every critical step
If you already have a development plan, internal expertise or selected partners, you may need additional capacity or specialist guidance at a critical stage. Clarenta can strengthen specific parts of your programme, challenge assumptions and connect strategy with execution, without disrupting the model you already have in place.

What our clients say


Case study: First-in-Human immuno-oncology across Europe and the US
A European immuno-oncology biotech needed to deliver its first Phase I/IIa study across Europe and the US while building its internal Clinical Operations capability. Clarenta supported study design, led European submissions and delivery, coordinated specialist partners, and oversaw the US CRO.
The European submission was completed within two weeks of the final protocol, with the first patient enrolled on schedule. Clarenta recruited 262 patients across Europe and was subsequently awarded a second study.
