About Devonian

Devonian is a late stage botanical pharmaceutical company with novel therapeutic approaches
targeting unmet medical needs. Devonian’s core strategy is to develop prescription botanical drugs.
This strategy is supported by US-FDA set of regulatory guidelines favouring a more efficient drug
development pathway versus traditional prescription medicines. Devonian is based on a
broad-based platform originating from over ten years of research. This platform provides a unique
process of extraction, purification, stabilization and conditioning of a molecular complex
responsible for the photosynthetic process in plants and algae: The Supra Molecular Complex
Extraction and Stabilisation Technology (SUPREX). The “Thykaminetm” is the first product issued
from this platform. The potent anti-inflammatory and anti-oxidative activities of “Thykaminetm” have been demonstrated in several pre-clinical experiments as well as in a Phase 2a ‘‘proof of
concept’’ clinical study in patients with mild-to-moderate distal ulcerative colitis. The product is
now moving into large phase 2 clinical trials in two therapeutic areas: Ulcerative Colitis and
Atopic Dermatitis. While the development of prescription botanical drugs is its core business,
Devonian is also involved in the development of high value derma-cosmeceutical products as part
of a secondary strategy to generate short-term revenues and optimize manufacturing efficiency.
