Transient fluid flow improves photoimmunoconjugate delivery and photoimmunotherapy efficacy

Published in: iScience Authors: Aaron J. Sorrin, Keri Zhou, Katherine May, Cindy Liu, Kathryn McNaughton, Idrisa Rahman, Barry J. Liang, Imran Rizvi, Dana M. Roque, Huang-Chiao Huang    Published in: iScience Authors: Aaron J. Sorrin, Keri Zhou, Katherine May, Cindy Liu, Kathryn McNaughton, Idrisa Rahman, Barry J. Liang, Imran Rizvi, Dana M. Roque, Huang-Chiao Huang   The study showed that fluid flow induced shear stress increased the photocytotoxicity of different photosensitizers tested (BPD, PIC, PIC-coated liposome) against ovarian cancer cells. The cellular delivery of photosensitizers doubled compared to static conditions. Modulight laser was used for PDT activation together with photosensitizer(s). Circulating drugs in the peritoneal cavity is an effective strategy for advanced ovarian Continue reading →

Laser platform and light delivery optimization for bladder cancer treatment with a novel photosensitive drug

Presented in: SPIE BIOS 2023 Authors: Zoe Ylöniemi, Elias Kokko, Visa Kaivosoja, Ana Colucci, Eerika Suokas, Jukka-Pekka Alanko, Petteri Uusimaa, Modulight Corp.    Presented in: SPIE BIOS 2023 Authors: Zoe Ylöniemi, Elias Kokko, Visa Kaivosoja, Ana Colucci, Eerika Suokas, Jukka-Pekka Alanko, Petteri Uusimaa, Modulight Corp.   Non-muscle invasive bladder cancer (NMIBC) is a form of cancer with a relatively high 5-year survival rate but also very high recurrence rate. Photodynamic diagnosis is commonly used in standard clinical practice to visualize bladder cancer lesions as part of a TURBT procedure but photodynamic treatments utilizing photosensitive drugs have had limited success in clinical setting partly because of limitations in light Continue reading →

Towards Photodynamic Image-Guided Surgery of Head and Neck Tumors: Photodynamic Priming Improves Delivery and Diagnostic Accuracy of Cetuximab-IRDye800CW

Published in: Frontiers in Oncology Authors: Chanda Bhandari, John Fakhry, Menitte Eroy, Jane Junghwa Song, Kimberley Samkoe, Tayyaba Hasan, Kenneth Hoyt, Girgis Obaid    Published in: Frontiers in Oncology Authors: Chanda Bhandari, John Fakhry, Menitte Eroy, Jane Junghwa Song, Kimberley Samkoe, Tayyaba Hasan, Kenneth Hoyt, Girgis Obaid   The study showed that photodynamic priming (subtherapeutic doses of light using ML6500) of tumor microenvironment with nanoliposomal BPD is highly beneficial for delivery of antibodies (Cet-IR800) to H&N tumor in mice. Priming significantly improved the tumor accumulation of Cet-IR800 and diagnostic accuracy of tumor detection, as monitored with fluroescence imaging.   Read the article here

Breaking the selectivity‑uptake trade‑off of photoimmunoconjugates with nanoliposomal irinotecan for synergistic multi‑tier cancer targeting

Published in: Journal of Nanobiotechnology Authors: Barry J. Liang, Michael Pigula, Yan Baglo, Daniel Najafali , Tayyaba Hasan, Huang‑Chiao Huang    Published in: Journal of Nanobiotechnology Authors: Barry J. Liang, Michael Pigula, Yan Baglo, Daniel Najafali , Tayyaba Hasan, Huang‑Chiao Huang   The ML6600 laser was used to test the PDT efficacy of a novel photoimmunoconjugate-nanoliposome (PIC-Nal) comprising of EGFR-targeted Cetuximab, BPD photosensitizer and irinotecan chemoterapy inside a liposome. Different cancer cell lines were used and cell viability was determined after PDT.   Read the article here
