Age-related Macular Degeneration (AMD)

Age-related Macular Degeneration (AMD) Age-related Macular Degeneration (AMD) is a disease causing choroidal neovascularization (CNV) and consequent irreversible damage in the macula. AMD is classified into dry (atrophic) and wet (exudative) forms, with the latter causing faster vision loss and being the leading cause of blindness in people over 65. Introduction to AMD Age-related Macular Degeneration (AMD) is one of the leading causes for  visual impairment. AMD is charactirized by development of Choroidal neovascularization (CNV) and consequent irreversible damage in the macula. CNV means abnormal Continue reading →

Modulight Spotlights: LASER-SHARP RESEARCH – April 2024

 Modulight Spotlights: LASER-SHARP RESEARCH – April 2024 First-in-human, phase 1 clinical trial results with ML7710 have been published in a renowned journal Radiology by Timothy Baran and team at University of Rochester Medical Center. The trial investigated treatment of deep tissue abscesses using photodynamic therapy with methylene blue and ML7710 laser. Abscesses are painful collection of pus, usually caused by a bacterial infection. Standard treatment is abscess drainage and antibiotics, however treatment responses vary widely and are linked to prolonged hospital stay, costs, and patient discomfort, as well as increasing concerns for antibiotic-resistance. The trial in 18 Continue reading →

Robey, Graeme F. Woodworth, Michael M. Gottesman, Huang-Chiao Huang University of Maryland Glioblastoma (GBM) is hard to treat due to cellular invasion into functioning brain tissues, limited drug delivery, and evolved treatment resistance. Recurrence is nearly universal even after surgery, chemotherapy, and radiation. Photodynamic therapy (PDT) involves photosensitizer administration followed by light activation to generate reactive oxygen species at tumor sites, thereby killing cells or Continue reading →

ML7710 for photoactivated treatment of lung cancer

Deadliest cancer Precision with photoactivation Photoimmunotherapy with ML7710 offers a clinical therapeutic option for NSCLC patients even with advanced disease stage. Besides laser light, this therapy involves photoactivated drug, which can be activated precisely at the tumor site with laser fibers, hence minimizing drug effects to healthy tissues. Smaller invasiveness compared to surgery can enable patients to stay less time recovering at the hospital. It can also be repeated if needed multiple times without cumulating toxicities, unlike radiation therapy. Some previously inoperable tumors can decrease Continue reading →Deadliest cancer Lung cancer is the leading cause of cancer deaths worldwide, with more than 2.2 million cases and 1.8 million deaths each year [1]. Lung cancer can be divided into two types, small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC), with the latter accounting for about 85% of all lung cancer cases. NSCL is usually less sensitive to chemo- and radiotherapy and in many cases tumor cannot be removed surgically or has spread from lungs to distant sites at the time Continue reading →

Photodynamic Therapy of an Abdominal Abscess at the Time of Percutaneous Drainage

Published in: Cardiovascular and Interventional Radiology Authors: Timothy M. Baran, Ashwani Kumar Sharma    Published in: Cardiovascular and Interventional Radiology Authors: Timothy M. Baran, Ashwani Kumar Sharma   This article presents a successful case study from an ongoing Phase 1 clinical trial where methylene blue together with ML7710 is used to eradicate bacteria and biofilm in the treatment of persistent abscesses. The potential of Photodynamic Therapy (PDT) is explored as an adjunct treatment for recurrent or challenging-to-manage abdominal abscesses during percutaneous drainage procedures. Despite advancements in abscess drainage techniques and antibiotics, some cases exhibit low response rates and recurrences, 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 →

Pharmaceutical nanotechnology applied to phthalocyanines for the promotion of antimicrobial photodynamic therapy: A literature review

Published in: Photodiagnosis and Photodynamic Therapy Authors: Luciana Betzler de Oliveira de Siqueira, Ana Paula dos Santos Matos, Marcio Robert Mattos da Silva, Suvene Rocha Pinto, Ralph Santos-Oliveira, Eduardo Ricci-Júnior  Published in: Photodiagnosis and Photodynamic Therapy Authors: Luciana Betzler de Oliveira de Siqueira, Ana Paula dos Santos Matos, Marcio Robert Mattos da Silva, Suvene Rocha Pinto, Ralph Santos-Oliveira, Eduardo Ricci-Júnior   Phthalocyanines are photosensitizers activated by light at a specific wavelength in the presence of oxygen and act through the production of Reactive Oxygen Species, which simultaneously attack several biomolecular targets in the pathogen agent and, therefore, have multiple and variable action sites. This nonspecific action site bypasses conventional resistance mechanisms. Antimicrobial Photodynamic Therapy (aPDT) is Continue reading →

Modulight Spotlights: LASER-SHARP RESEARCH – February 2022

   Modulight Spotlights: LASER-SHARP RESEARCH – February 2022 Photocure’s blue light cystoscopy is a routine procedure in the management of bladder cancer as it results in better tumor visualization and removal. However, this study found that the positive effects of blue light cystoscopy could extend beyond visualization and result in the induction of systemic antitumor immunity, which can be further boosted with immune checkpoint inhibitors. Modulight nominated this study because bladder cancer is highly recurring and progressive disease with more than 200,000 deaths worldwide annually. Thus, Continue reading →
