Research Associate - Protein CMC

Precirix is a clinical-stage biopharmaceutical company dedicated to extending and improving the lives of cancer patients by designing and developing novel radiopharmaceuticals, using camelid-derived single-domain antibodies (sdAb) labeled with radioisotopes. The company’s lead product, CAM-H2, is being evaluated in a Phase I/II trial targeting metastatic HER2-positive cancer. In addition, the company has two product candidates in preclinical stage and is further broadening its platform through research on new targets, different isotopes, linker technology and combination therapies.
