ATONCO S.A.S. (‘ATONCO’) announced today that it has entered into a clinical research partnership agreement with the Institut de Cancérologie de l’Ouest (ICO Nantes Angers) regarding the clinical study of its CA-IX-binding antibody, ⁸⁹Zr-girentuximab, with PET imaging to document the absence of extravasation of radioactivity into the systemic circulation after intravesical instillation, and to visualize targeted papillary tumors.

This imaging and dosimetry study using ⁸⁹Zr-girentuximab is considered a “clinical proof of concept” prior to the subsequent therapeutic use of astatine-211 in a Phase I/II clinical development.

The clinical project will include 6 patients (3 men and 3 women), and is based on the license and development agreement between Telix and ATONCO for ATONCO to investigate the use of Telix’s Molecularly Targeted Radiation (MTR) intellectual property for the treatment of non-muscle-invasive bladder cancer resistant to standard therapies.

Under the agreement, ATONCO has a license to conduct R&D activities on girentuximab, radiolabeled with At-211, for the intravesical treatment of chemotherapy- or BCG-resistant bladder cancer, and subsequent commercialization of this product, if successful.

ATONCO will accelerate its therapeutic development targeting BCG-resistant bladder cancer. Dr. Caroline Rousseau, Head of Nuclear Medicine at the ICO (Institut de Cancérologie de l’Ouest) in Nantes, the clinical site and sponsor of the study, will lead the feasibility study as principal investigator.

Jean-François Chatal, ATONCO’s founder and medical director, said: “The unmet clinical need for non-muscle-invasive bladder cancer refractory to BCG or chemotherapy fits well with the radiophysical characteristics of astatine-211 with tumor targets rapidly accessible after intravesical instillation of girentuximab and consisting of thin superficial tumor layers corresponding to the short path length of the alpha particles. This alpha-immunotherapy should make it possible to avoid very uncomfortable radical cystectomies and thus prolong the life and improve the quality of life of our bladder cancer patients. We are confident that this is the first successful step in our partnership with ICO.”

Sylvain Fanier, President of ATONCO, said, “We are delighted to partner with ICO, one of the most respected clinical institutions in the field of oncology, and to develop with our local academic and preclinical CRO partners in Nantes an innovative Molecular Targeted Radiation (MTR) solution to improve the management of patients with non-muscle-invasive bladder cancer.”

In 2018, bladder cancer was the fifth most common cancer in the United States, with an estimated 82,501 new cases diagnosed and 17,755 deaths resulting from bladder cancer.

Australian biopharmaceutical company Telix Pharmaceuticals Limited (ASX: TLX) has signed an agreement with France’s ATONCO S.A.S to investigate the use of Telix’s Molecularly Targeted Radiation (MTR) technology.

The license and development agreement will allow ATONCO to study the use of MTR technology for the treatment of non-muscle-invasive bladder cancer that is resistant to standard therapies.

Under the agreement, ATONCO will receive a license to select components of Telix’s antibody portfolio for use with astatine-211, an alpha-emitting radioisotope, to treat bladder cancer that is no longer responsive to standard therapies.

Dr. Christian Behrenbruch, CEO of Telix, said astatine-211 emits alpha particles with a favorable emission profile that is well suited for bladder cancer because it delivers highly localized antitumor radiation with minimal impact on surrounding tissue.

Under the agreement, Telix may receive development milestone payments of approximately A$30 million, as well as royalties upon successful commercialization. Telix retains a right to reacquire the program if clinical data are conclusive.

This collaboration with ATONCO represents a new milestone for Telix, as it is the first time we have licensed our intellectual property to a third party,” said Dr. Behrenbruch. “While we maintain a disciplined focus on our prostate, kidney and brain cancer programs, this collaboration demonstrates the attractiveness of Telix’s technology to our customers, this collaboration demonstrates the attractiveness of our intellectual property to other companies and allows our assets to be developed for new cancer indications beyond Telix’s core focus areas, while giving us the opportunity to re-annex the program if promising clinical data warrant.”

ATONCO CEO Professor Jean-Francois Chatal said the collaboration with Telix Pharmaceuticals is driven by the clinical potential of alpha immunotherapy for non-muscle-invasive refractory bladder cancer.

“This is truly a clinical indication with currently unmet therapeutic efficacy that could benefit from a new treatment through the antibody-targeted features of astatine-211.”

In 2018, bladder cancer was the fifth most common cancer in the United States, with an estimated 82,501 new cases diagnosed and 17,755 deaths resulting from bladder cancer. ATONCO is a privately held French company that develops radiopharmaceuticals for oncology applications. A spin-off of the world-class radiochemistry cluster that includes Nantes University Hospital and the ARRONAX Public Interest Group (GIP), ATONCO and its academic collaborators are dedicated to the clinical use of astatine-211.
