Radiopharm Theranostics Ltd.’s radiotracer RAD-101 met the primary endpoint in 92% of patients in the phase IIb imaging trial in brain metastases, according to interim results. To date, 11 of the 12 patients treated with RAD-101 (F18-Pivalate) achieved concordance with MRI (the primary endpoint) as assessed by PET imaging of brain metastases. The results showed significant and selective tumor uptake, and images confirm metabolic activity in brain metastases compared to equivocal MRI findings.
One of the functions of tumor-associated macrophages (TAMS) is to protect the tumor against the immune system, inhibiting T-cell engagement and reducing the efficacy of checkpoint inhibitors. Polyamidoamine hydroxyl dendrimers (HDs) target TAM without the need of a targeting ligand and are retained by TAMs for up to 1 month allowing radiation to deposit in the tumor.
Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by inflammation and damage of the joints. PET/CT imaging is a useful tool for early disease assessment and monitoring treatment efficacy.
Researchers from Universidad Carlos III de Madrid presented the development and preclinical characterization of a novel specific radiotracer for the diagnosis of Clostridioides difficile infection (CDI).
Fibroblast activation protein (FAP) is absent or expressed at a very low level in normal tissues. However, it is overexpressed in around 80% of solid tumor stroma.
Monoacylglycerol lipase (MAGL) is a key regulator of the endocannabinoid system (ECS), which has a critical neuromodulatory involvement in numerous functional mechanisms in the CNS. Based on this, MAGL is considered a promising therapeutic target in neuroinflammation and neurodegeneration. Researchers from ETH Zürich and affiliated organizations have recently presented their work on (R)-[18F]YH-134, a novel reversible radiotracer for imaging MAGL in the brain.
Researchers from Helmholtz-Zentrum Dresden-Rossendorf presented the discovery of novel small molecule-based radiotracers for PD-L1 PET or SPECT imaging.
