atbtherapeutics, a biopharmaceutical company building an oncology pipeline using its antibody–toxin-bioengineered “atbody,” has entered a long-term manufacturing agreement with iBio CDMO, a global leader in plant-based biologics manufacturing located in the US.

In this agreement, atbtherapeutics and iBio CDMO will work together for the industrialization of the GMP manufacturing process of atbtherapeutics’ atbodies – game-changer biologics of targeted antibody-based therapy in development for the treatment of haematological malignancies and solid tumors.

What Makes atbody Unique

atbody novel biologic is differentiated by a unique composition and novel mechanism of action, together aiming to extend the therapeutic window of current targeted therapies. The atbody is a single entity composed of an antibody that delivers a potent peptide payload, unlocked into the cancer cell following a peptide linker cleavage.

The novelty of this sophisticated atbody results from atbtherapeutics’ truly distinct method of production, the atbiofarm technology. This patented technology leverages plant expression systems to manufacture biologics that classic systems cannot achieve, in a single-step process. atbiofarm technology is transferable within the FastPharming technology developed by iBio CDMO for years. Therefore, iBio CDMO’s plant system knowledge and cutting-edge facility will allow atbtherapeutics to rapidly scale up the production of atbodies at industrial level.

The agreement with iBio CDMO will ensure the manufacturing of two main programs for pre-clinical and clinical trials and will allow atbtherapeutics to focus on the development of its oncology pipeline.

Bertrand Magy, CEO of atbtherapeutics, commented, “iBio’s proven expertise in plant-based manufacturing will be highly valuable as we prepare for the first pre-clinical trials for our lead atbody program. With the support of iBio, we are confident that we will be able to rapidly progress towards the clinic with our lead product candidates for the treatment of cancer. We are thrilled to be working with such a well-established plant molecular farming company.”

Tom Isett, chairman & CEO of iBio, added: “We are pleased to be chosen as the process development and manufacturing partner for atbtherapeutics, whose platform technology offers a unique approach for hard-to-treat hematological malignancies and solid tumors. We are looking forward to helping atbtherapeutics rapidly build a scalable manufacturing process so that its atbody drug candidates may quickly reach the clinic and begin to realize their potential in oncology.”
