A Phase I/II Open Label Single Centre Trial to Assess the Safety, Tolerability and Efficacy of Single Dose Neoadjuvant Anti-CLEVER-1 Antibody Bexmarilimab in Localised Renal Cell and Colon Carcinoma

Bexmarilimab treatment has demonstrated tolerable safety profile and anticancer efficacy in some subjects with advanced malignancies. This is the first study to investigate the effect of single neoadjuvant dose of anti-CLEVER-1 antibody bexmarilimab prior to radical surgery of renal cell and colon cancers. We expect that the single dose will demonstrate measurable effects on the tumour immunological microenvironment as well as systemic effects on subject´s immunological status and that this evidence may be used to guide future neoadjuvant studies. There will be a dose escalation to investigate the effect of different doses of bexmarilimab. In addition to subjects receiving single neoadjuvant dose of bexmarilimab, there will be an observational cohort without Investigational Medicinal Product (IMP) for either cancer. All patients participating in the study (whether in investigational or observational cohort) will attend each visit and are assessed for the same endpoints.
