Particle Beam Radiobiology Status and Challenges: A PTCOG Radiobiology Subcommittee Report.

Particle therapy (PT) represents a significant advancement in cancer treatment, precisely targeting tumor cells while sparing surrounding healthy tissues thanks to the unique depth-dose profiles of the charged particles. Furthermore, their linear energy transfer and relative biological effectiveness enhance their capability to treat radioresistant tumors, including hypoxic ones. Over the years, extensive research has paved the way for PT's clinical application, and current efforts aim to refine its efficacy and precision, minimizing the toxicities.

Single-center, double-blind, randomized, placebo-controlled pilot study of Canoxidin® for prevention of catheter encrustation in patients with indwelling catheters.

Introduction And Objectives: Long-term use of an indwelling catheter is associated with complications such as catheter encrustation and infection. Canoxidin® is a novel oral treatment that can potentially prevent catheter encrustation, as it contains a urine acidifier and a combination of two crystallization inhibitors. This study aimed to evaluate the effects of Canoxidin® on catheter encrustation in patients with indwelling Foley catheters.

Target engagement of an anti-MT1-MMP antibody for triple-negative breast cancer PET imaging and beta therapy.

Purpose: Triple-negative breast cancer (TNBC) is a highly aggressive subtype of breast cancer that lacks effective diagnostic and therapeutic options. Membrane type 1 matrix metalloproteinase (MT1-MMP) is an attractive biomarker for improving patient selection. This study aimed to develop a theranostic tool using a highly tumour-selective anti-MT1-MMP antibody (LEM2/15) radiolabelled with Zr for PET and Lu for therapy in a TNBC murine model.

Pharmacokinetics and safety of LEAD-452, an EGFR-specific 4-1BB-agonistic trimerbody in non-human primates.

LEAD-452 is a humanized bispecific EGFR-targeted 4-1BB-agonistic trimerbody with a unique trimeric configuration compared to other 4-1BB-specific antibodies that are currently in development. Indeed, enhanced tumor-specific costimulation and very remarkable safety and efficacy profiles have been observed in mouse models. Here, we conducted for the first time a preclinical pharmacokinetic and toxicity study in non-human primates (NHP) (Macaca fascicularis).

In Vivo Detection of Infections Using Radiolabeled Antibodies Specific for Bacterial Toxins.

Purpose: The Gram-positive bacterium is one of the leading causes of infection in humans. The lack of specific noninvasive techniques for diagnosis of staphylococcal infection together with the severity of its associated complications support the need for new specific and selective diagnostic tools. This work presents the successful synthesis of an immunotracer that targets the -toxin released by .
