Unlocking the full potential
of highly potent anticancer drugs
We aim to enhance the best anticancer treatments by increasing their tumor accumulation.
Despite all the efforts in the fight against cancer, some tumors are still resistant to currently available treatments. Highly active pharmaceutical ingredients (HPAPI) are drugs 100 to 1000 times more active than traditional chemotherapies. Unfortunately, patients cannot benefit from HPAPIs as they distribute homogeneously throughout the body after administration. This limits the dose that can be administered, due to toxicities, and hampers their full potential.
At Imescia we tackle this problem by leveraging our unique polymer prodrug technology that allows an increased tumor accumulation of HPAPIs therefore enhancing their efficacy.
Delivering the HPAPIs at the tumor site for efficacy with limited side effects.
Our technology consists in a prodrug polymer approach combining three essential elements:
- Drug: we work with the most promising HPAPI that did not reach the clinic due to a limited maximal tolerated dose.
- Polymer: our innovative highly hydrophilic polymer has been tailored to accumulate at the tumor site thanks to its physico-chemical properties.
- Linker: the polymer prodrug as a whole is inactive and does not induce toxicities. The linker is designed to specifically release the drug into the tumor microenvironment, sparing the healthy tissues.
The combination of these three elements limit the toxicities of the HPAPI and allow increasing the maximal tolerated dose. The improvement of the tumor accumulation increases drug concentration inside the tumor thus leading to a better anticancer effect.
Our solution is unique and beyond the state of the art based on 3 criteria:
- Our innovative polymer is non toxic (> 10 000 times less toxic than the drug). No risk of toxicities due to the polymer.
- Our polymers are extremely hydrophilic, we can solubilize even the most insoluble small molecules with short polymer chains. Our vector is smaller than nanoparticles which allows a penetration within the deeper layers of the tumor.
- Our approach is receptor agnostic compared with the antibody drug conjugate technology. We can address a wide range of cancers and most importantly those that do not express a specific receptor and which are still unmet medical needs.
Side effects stem from unspecific drug distribution
Preferential tumor accumulation with Imescia's approach
HPAPI are limited by their maximal tolerated dose
Imescia's technology increases HPAPI's maximal tolerated dose at least 10-fold
Low maximal tolerated dose → low efficacy in vivo
Significantly increased tumor growth inhibition with Imescia's prodrug
We are advancing in the preclinical development of our lead product IMA-01, based on a highly potent anticancer drug.
With IMA-01 we seek to address tumors with an important unmet medical need. We have a strong in vivo proof-of-concept and are gathering efficacy results on several cancer models.
We are actively looking for partnership opportunities to adapt our technology to the best HPAPIs
Our prodrug polymer technology is a platform that can be adapted to a wide variety of small molecules, peptides and oligonucleotides.
We improve API solubility, stability, pharmacokinetics (enhanced half-life) and do not need to use additional surfactants or lipids for the formulation. This is particularly of interest for small molecules HPAPI, peptides and oligonucleotides. Get in touch with us to learn more about the technology.
