CAM-H2 production at Evergreen marks the expansion of Precirix’ clinical trial to the US

Precirix is running a Phase I/II clinical trial in Canada to evaluate the safety, tolerability and efficacy of CAM-H2 in HER2-positive metastatic breast, gastric and gastroesophageal cancer, including patients with brain metastases. With Evergreen ready for the production of clinical trial batches, Precirix is significantly increasing its manufacturing capacity in anticipation of patient recruitment in the US.

Evergreen will produce CAM-H2 in therapeutic as well as imaging doses. Patients will receive a first imaging dose to evaluate HER2 expression in the lesions followed by therapeutic doses in case they qualify for CAM-H2 treatment.

Dimitrios Mantzilas, Chief Technology Officer of Precirix, comments: “We are proud to announce the first clinical batch production at Evergreen. The combination of Precirix’ innovative technology and know-how with Evergreen’s technical capabilities have resulted in a smooth technology transfer. We look forward to continuing our collaboration and to evaluate CAM-H2 in patients throughout North America”.

James Cook, Chief Executive Officer of Evergreen Theragnostics, said: “We are very excited to play a role in the development of CAM-H2 by making this important product broadly available for clinical trials. We have a great collaboration with Precirix and are committed to ensuring high quality and high reliability supply from our factory in Springfield, New Jersey.”

About Precirix

Precirix is a private, clinical-stage biopharmaceutical company dedicated to extending and improving the lives of cancer patients by designing and developing precision radiopharmaceuticals, using camelid single-domain antibodies labeled with radioisotopes. The company has a broad pipeline with one product candidate in a Phase I/II clinical trial and two in advanced preclinical stage. Research on multiple isotopes, linker technology and combination therapies further expand the platform. Precirix’ technology also allows for a theranostic approach, where patients can be selected using a low dose/imaging version of the product, followed by a therapeutic dose for treatment.

About CAM-H2

CAM-H2 comprises a single-domain antibody targeting HER2, covalently linked to iodine-131. Single-domain antibodies are ideally suited for targeted delivery of radiation to tumors given their size, specificity and pharmacokinetic characteristics. Imaging studies conducted with the HER2 targeting single-domain antibody labelled with gallium-68 have demonstrated specific uptake and retention in primary, metastatic and brain lesions in HER2-positive breast cancer patients. CAM-H2 is currently being evaluated in a Phase I/II clinical study including HER2-positive metastatic breast, gastric and gastroesophageal cancer patients.
