ML7710 for fluorescence imaging: Detection of colorectal polyps in humans using c-Met targeted fluorescent peptide

Motivation for the study Polyps are small growths on the inner lining of the colon or rectum, affecting around 1 in 4 people over the age of 50. Certain types of polyps may eventually become cancerous, and colon cancer prevention relies on colonoscopy using white light to detect and remove the polyps. However, small and flat polyps are difficult to detect and frequently missed with this technique. More precise methods to detect polyps before they progress to colorectal cancer are urgently needed. GE Healthcare’s patented EMI-137 Continue reading →Customer Case Research by: GE Healthcare is a manufacturer and distributor of diagnostic imaging agents and radiopharmaceuticals, R&D collaborations with Leiden University MC for early detection of colorectal tumors.

Loof, Pål Kristian Selbo, Hans Olivecrona, Sjoerd H. van der Burg, Anders Høgset    Published in: Frontiers in Immunology Authors: Tone Otterhaug, Sylvia Janetzki, Marij J. P. Welters, Monika Håkerud, Anne Grete Nedberg, Victoria Tudor Edwards, Sanne Boekestijn, Nikki M. Loof, Pål Kristian Selbo, Hans Olivecrona, Sjoerd H. van der Burg, Anders Høgset   Open-label phase 1 study to assess safety and local tolerance to PCI vaccination (fimaVACC). Peptide and protein-based vaccination coupled with PCI platform was safe in healthy volunteers (n=96) and significantly enhanced T-cell responses (over 10-fold compared to vaccination without PCI platform). The optimal and safe Continue reading →

Combination of ALA-induced fluorescence-guided resection and intraoperative open photodynamic therapy for recurrent glioblastoma: case series on a promising dual strategy for local tumor control

Published in: Journal of Neurosurgery Authors: Stephanie Schipmann, Michael Müther, Louise Stögbauer, Sebastian Zimmer, Benjamin Brokinkel, Markus Holling, Oliver Grauer, Eric Suero Molina, Nils Warneke, Walter Stummer    Published in: Journal of Neurosurgery Authors: Stephanie Schipmann, Michael Müther, Louise Stögbauer, Sebastian Zimmer, Benjamin Brokinkel, Markus Holling, Oliver Grauer, Eric Suero Molina, Nils Warneke, Walter Stummer   Report on results from intraoperative open PDT compassionate care of 20 recurrent glioblastoma patients. ML7710 was used only for PDT (Zeiss surgical microscope used for fluorescence visualization of PPIX). Results suggest that combining PDT with 5-ALA FGR (fluorescence-guided resection) is effective (effect of PDT was seen in 80% of patients) and safe (only one adverse event was Continue reading →

Disulfonated tetraphenyl chlorin (TPCS2a)-induced photochemical internalisation of bleomycin in patients with solid malignancies: a phase 1, dose-escalation, first-in-man trial

Published in: Lancet Oncology Authors: Ahmed A Sultan, Waseem Jerjes, Kristian Berg, Anders Høgset, Charles A Mosse, Rifat Hamoudi, Zaid Hamdoon, Celia Simeon, Dawn Carnell, Martin Forster, Colin Hopper    Published in: Lancet Oncology Authors: Ahmed A Sultan, Waseem Jerjes, Kristian Berg, Anders Høgset, Charles A Mosse, Rifat Hamoudi, Zaid Hamdoon, Celia Simeon, Dawn Carnell, Martin Forster, Colin Hopper   Photochemical internalization with bleomycin was studied in a Phase 1, first-in-man trial for local recurrent, advanced, or metastatic H&N cancer. Modulight laser was used for activation of TPCS2a photosensitizer at the surface of the target tumor. 12 patients completed the 3-month follow-up, with maximum tolerated dose of TPCS2a being established to 1.0 mg/kg.   Read Continue reading →
