Selective bone targeting, local drug release and improved therapeutic index.

Active Pharmaceutical Ingredient (API) – Vectorization of molecules with different functional groups

Custom linkers

– Selective local drugs release (pH, enzymes, …)
– Modulation of drug’s LogP, solubility, transport, …

Innovative Bone Targeting Vectors

– Improved drug distribution Vectors
– Modulation of retention in the bone
– Modulation of antiresorptive action

API releasing group

– Key for API liberation
– Modulates API release rate and cleavage conditions

Engineering innovative HBP vectors for targeting bones and joints

OUR STORY

With strong internal capabilities in Chemistry and Biology, Atlanthera has built a unique R&D know-how in the vectorization of APIs through its innovative flagship technology «bifunctional HBP molecules» over the last 13 years

Development of specific and custom “linkers”
Development of new vectorized
APIs (bone and joints local sustained release)
Improved compliance to treatment
Repositioning of drugs already on the market, salvage of a drug that has been served a Clinical Hold order, find a new indication for a drug
Generation of new patentable entities Reducing systemic toxicity/

OUR COMMITMENT

We are a biotechnology company that develops new treatments for people with bone/joint diseases such as osteosarcoma, bone metastases from various primary cancers, inflammatory diseases such as arthritis and osteoarthritis, bone microbial such as osteomyelitis and septic arthritis.

We have developed a portfolio of new entities (Human and/or Veterinary use) that stand out from conventional therapies by targeting the active ingredient as closely as possible to the tissues to be treated (bone and/or joints), locally sustained and thus reducing systemic adverse effects.
