The Role of YAP1 in Fibrosis Explored Through Its Local Inhibition With Verteporfin in Surgical Wounds: A Randomized Controlled, Prospective, Evaluator-blinded Proof-of-concept Study.

When we get injured, our body naturally tries to heal. In adults, this healing often leads to scars - thick, stiff tissue known as fibrotic tissue. Unlike normal tissue, fibrotic tissue doesn't function properly and can cause serious health problems, depending on the affected organ. Once it forms, fibrosis is usually permanent.
A good example of the fibrosis process is the healing of our skin: after a cut or surgery, the resulting scar is a type of fibrosis. Special cells called fibroblasts are key players in this process.
Our study looks at a drug called verteporfin, which is already approved both in Europe and the U.S. Previous research on mice and human cells suggests it can reduce or even prevent fibrosis.
We are now testing, clinically, histologically and by scRNA-seq, whether injecting verteporfin into the skin during wound healing, specifically after surgical procedures, can prevent thick, rigid scars from forming. Since the skin is easy to observe and sample, it offers a great model for studying this.
Will verteporfin have an impact on how surgical wounds heal? That's what we aim to find out.

Open-label Clinical Phase 1/2 Study to Assess the Safety and Efficacy of the SpectraCure P18 System and Verteporfin for Injection for the Treatment of Primary Localized Prostate Cancer

The goal of this study is to obtain safety data, establish dose parameters, and effectiveness of treatment for the SpectraCure P18 System with IDOSE®, together with verteporfin for injection (VFI) as photosensitizer, for the treatment of primary localized prostate cancer.
The study will be divided into two parts, with Phase I, dose-escalation, to study safety and establish an effective light dose, followed by Phase II, cohort expansion, to evaluate clinical efficacy and confirm safety/tolerability. The subjects will be followed for a period of 18 months to determine the primary outcome. The long-term follow-up is an additional 18 months, i.e. a total of 36 months.
Interstitial Photodynamic Therapy (PDT) will be performed during general anesthesia. Optical fibers will be inserted into the prostate with a transperineal approach using transrectal ultrasound guidance. The intent is to deliver an adequate light dose throughout the prostate. Subjects will receive VFI intravenously, approximately 60-90 minutes prior to light delivery.

Photodynamic Priming to Facilitate Immunologic Activity of Anti-PD1 in Patients with Pancreatic Cancer

This phase II trial tests how well photoradiation with verteporfin and pembrolizumab plus standard of care chemotherapy works in treating patients with pancreatic cancer that cannot be removed by surgery (unresectable), that has spread to nearby tissue or lymph nodes (locally advanced) or to other places in the body (metastatic). Photoradiation uses light activated drugs, such as verteporfin, that become active when exposed to light. These activated drugs may kill tumor cells. Vertoporfin may also increase tumor response to immunotherapy. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as modified fluorouracil, leucovorin, irinotecan, and oxaliplatin (mFOLFIRINOX), work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Photoradiation with verteporfin and pembrolizumab plus standard of care chemotherapy may kill more tumor cells in patients with unresectable, locally advanced or metastatic pancreatic cancer.

Targeting breast cancer stem cells in ER-positive breast cancer by repurposing the benzoporphyrin derivative verteporfin as a YAP/TAZ small molecule inhibitor

Article

Author: Roy, Himansu ; Chatterji, Urmi ; Talukdar, Priyanka Dey

BACKGROUND:

Current treatment strategies for hormone-dependent breast cancers, including adjuvant endocrine therapy, often fail due to persistence of breast cancer stem cells (brCSCs), which are significant contributors to tumor recurrence and treatment resistance. Therefore, gaining deeper insights into the molecular regulators driving breast cancer aggressiveness is important. Moreover, given the complexities and expenses involved in developing new pharmacological agents, the strategic repurposing of existing FDA-approved drugs to target these key molecular pathways presents a compelling approach for identifying novel therapeutic interventions aimed at mitigating tumor refractoriness.

METHODS:

The study employs survival analysis from TCGA database, protein expression analyses alongside aldefluor assays, sphere formation efficiency tests to evaluate cellular stemness, and DCFDA analysis combined with antioxidant enzyme assays to investigate redox imbalance in brCSCs. These analyses were conducted following the genetic deletion of YAP/TAZ and pharmacological treatment with verteporfin.

RESULTS:

The study demonstrated that transcriptional co-activators YAP/TAZ are significantly upregulated in chemotreated ER⁺ patient breast tumors and MCF-7 mammospheres, where it was found to interact with the transcription factor SOX2 within the nuclear compartment. Genetic ablation and pharmacological inhibition of YAP/TAZ markedly impaired stemness properties and disrupted redox homeostasis in the mammospheres. Additionally, treatment with verteporfin led to a substantial reduction in the frequency and viability of brCSCs, suggesting their effective eradication.

CONCLUSION:

This study highlights the potential of repurposing verteporfin, an FDA-approved drug originally formulated for age-related macular degeneration, as a therapeutic agent for targeting YAP/TAZ-mediated stemness and redox balance in brCSCs, thereby reducing their viability in ER-positive breast cancers.

Long-Term retrospective analysis of retinal pigment epithelium atrophy and secondary hyperplasia following verteporfin photodynamic therapy

Article

Author: Hsu, Sung-Ting ; Chen, Lee-Jen ; Tsai, Hsiang-Ling ; Chiu, Ning ; Lai, Yung-Jen ; Chiu, Fang-Yi ; Chan, Wei-Chun

PURPOSE:

To identify risk factors for retinal pigment epithelium (RPE) atrophy associated with verteporfin photodynamic therapy (PDT), with or without secondary RPE hyperplasia, and to evaluate long-term visual outcomes.

MATERIALS AND METHODS:

This retrospective study analyzed 197 eyes of 180 patients who underwent verteporfin PDT between 2000 and 2023. Baseline demographic and clinical characteristics were evaluated.

RESULTS:

Among 197 eyes that underwent one or more sessions of PDT, PDT-induced RPE atrophy was observed in 2 eyes (2.4 %) with wet age-related macular degeneration (wet AMD) or polypoidal choroidal vasculopathy (PCV) and in 1 eye (3.8 %) with central serous chorioretinopathy (CSC). In contrast, 18 eyes (22.2 %) with myopic choroidal neovascularization (mCNV) developed PDT-induced RPE atrophy. Subgroup analysis revealed that in the mCNV group, patients with PDT-induced RPE atrophy were significantly younger (36.5 ± 13.7 years vs. 46.3 ± 12.8 years; P < 0.001) and underwent more PDT sessions (2.6 ± 1.8 vs. 1.5 ± 0.8; P < 0.001) than those without atrophy. Five patients developed secondary RPE hyperplasia, all from the mCNV group.

CONCLUSION:

Verteporfin PDT rarely induces RPE atrophy in patients with wet AMD, PCV, and CSC. However, in patients with myopic CNV, PDT may occasionally cause alterations in the RPE, including both atrophy and secondary hyperplasia. While PDT-induced RPE atrophy was not a statistically significant predictor of best-corrected visual acuity at the final follow-up in the mCNV and wet AMD/PCV groups in the linear regression analysis, it was a significant factor in the CSC group.

Protoporphyrin IX-Derived Ruthenium(II) Complexes for Photodynamic Therapy in Gastric Cancer Cells

Article

Author: Gómez Vidales, Virginia ; Mellitzer, Georg ; Gaiddon, Christian ; Orvain, Christophe ; Verget, Lucas ; Thibaudeau, Chloé ; Le Lagadec, Ronan ; Recberlik, Sevda ; Murillo, María Isabel ; Restrepo-Acevedo, Andrés

In recent years, photodynamic therapy (PDT) has emerged as a promising alternative to classical chemotherapy for treating cancer. PDT is based on a nontoxic prodrug called photosensitizer (PS) activated by light at the desired location. Upon irradiation, the PS reacts with the oxygen present in the tumor, producing cytotoxic reactive oxygen species (ROS). Compounds with highly conjugated π-bond systems, such as porphyrins and chlorins, have proven to be excellent light scavengers, and introducing a metal atom in their structure improved the generation of ROS. In this work, a series of tetrapyrrole-ruthenium(II) complexes derived from protoporphyrin IX and the commercial drug verteporfin were designed as photosensitizers for PDT. The complexes were almost nontoxic on human gastric cancer cells under dark conditions, revealing remarkable cytotoxicity upon irradiation with light. The ruthenium atom in the central cavity of the chlorin ligand allowed combined mechanisms in photodynamic therapy, as both singlet oxygen and superoxide radicals were detected. Additionally, one complex produced large amounts of singlet oxygen under hypoxic conditions. Biological assays demonstrated that the ruthenium derivatives caused cell death through a caspase 3 mediated apoptotic pathway and via CHOP, an endoplasmic reticulum stress-inducible transcription factor involved in apoptosis and growth arrest.

Research Funded by Bay Area Lyme Foundation Identifies New Investigational Therapy Regimen Capable of Irreversibly Damaging Lyme Bacteria in Laboratory Tests

Inspired by research that targets cancer tumors, these new findings in Lyme could also lead to novel R&D strategies for other diseasesPORTOLA VALLEY, Calif., Nov. 01, 2023 (GLOBE NEWSWIRE) -- Bay Area Lyme Foundation, a leading sponsor of Lyme disease research in the US, today announced the development of a potential new drug, HS-291, that targets and destroys Borrelia burgdorferi, the bacterium that causes Lyme disease. Published in the peer-reviewed journal Cell Chemical Biology, this laboratory study represents a novel paradigm shift for anti-microbial treatment research as it is the first to target and inhibit Borrelia burgdorferi HtpG (high temperature protein G), a specific type of enzyme within the bacteria that causes Lyme disease— a condition affecting nearly 500,000 new patients annually. The research was conducted at Duke University School of Medicine, with collaboration from University of North Carolina, Tulane University, and Stanford University, and HS-291 is currently in preclinical stage testing at UC Davis. “As Lyme disease is currently treated with broad spectrum antibiotics and there are no targeted treatments, we are particularly excited about this discovery, and hopeful that our novel Lyme disease therapeutic HS-291 will specifically destroy the Lyme bacterium without off-target effects or antibiotic resistance,” said Timothy Haystead, PhD, professor of Pharmacology and Cancer Biology, Duke University School of Medicine, Bay Area Lyme Foundation grantee, and co-lead author. “This research has been an incredible opportunity to leverage knowledge from oncology to Lyme disease in order to design an investigational therapeutic that could one day benefit hundreds of thousands of patients with Lyme.” This new discovery has implications beyond Lyme disease as it demonstrates that using the drug HS-291 to deliver cellular toxins to HtpG, a type of non-essential enzyme that assists the folding or unfolding of large and complex proteins, greatly expands what can be considered druggable within any pathogen and opens a whole new area of infectious disease research. When activated, HS-291, an inhibitor of HtpG tethered to the photoactive cellular toxin verteporfin, causes discrete protein modifications, which wreaks havoc on the Lyme disease bacterium’s DNA. This impacts multiple processes including nucleoid collapse and cell wall disruptions. A single dose of HS-291, when activated by light, irreversibly damages Borrelia proteins in close proximity of Bb HtpG in vitro. “Antibiotics used to treat Lyme disease do not always work for all patients, which causes many to suffer for years with extreme symptoms including neurocognitive issues, disabling fatigue and sleep disruption,” said Linda Giampa, executive director of the Bay Area Lyme Foundation. “Bay Area Lyme concentrates on funding innovative research, including projects where knowledge can be deployed from other areas of medicine. We hope that this discovery will inspire others to join us in investing in impactful, translational research to bring relief to patients.” This research was made possible by a 2020 Bay Area Lyme Foundation grant of more than $2 million to Duke University School of Medicine in honor of Neil Spector, MD, a renowned oncologist who passed away from complications of Lyme disease that had been misdiagnosed for years. He encouraged scientists to take cancer staging techniques and immunotherapy learnings from oncology and apply them to Lyme research. Dr. Spector was the Sandra Coates associate professor in the Duke University Department of Medicine and also served on Bay Area Lyme Foundation’s Scientific Advisory Board. Haystead and Spector joined forces as Spector sought to leverage his knowledge of oncology to help better understand Lyme disease, and Haystead’s research is focused on the use of chemical biology approaches to define novel drug targets focused on the treatment of hypertension, obesity, cancer, inflammatory and infectious disease. Bay Area Lyme Foundation also funded University of North Carolina collaborator, Matt Redinbo, PhD’s research on HS-291; his lab’s crystallography work was instrumental in the discovery process. Bay Area Lyme Foundation’s research grant program was made possible by the support from the Fairbairn Family, the Younger Family Fund, and Project Lyme. About Lyme disease The most common vector-borne infectious disease in the US, Lyme disease is a potentially disabling infection caused by bacteria transmitted through the bite of an infected tick to people and pets, and may also be passed from a pregnant mother to her unborn baby. If caught early, most cases of Lyme disease can be effectively treated, but it is commonly misdiagnosed due to lack of awareness and inaccurate diagnostic tests. There are approximately 500,000 new cases of Lyme disease each year, according to statistics released in 2018 by the CDC. As a result of the difficulty in diagnosing and treating Lyme disease, up to two million Americans may be suffering from the impact of its debilitating long-term symptoms and complications, according to Bay Area Lyme Foundation estimates. About Bay Area Lyme Foundation Bay Area Lyme Foundation, a national organization committed to making Lyme disease easy to diagnose and simple to cure, is the leading public not-for-profit sponsor of innovative Lyme disease research in the US. A 501c3 organization based in Silicon Valley, Bay Area Lyme Foundation collaborates with world-class scientists and institutions to accelerate medical breakthroughs for Lyme disease. It is also dedicated to providing reliable, fact-based information so that prevention and the importance of early treatment are common knowledge. A pivotal donation from The LaureL STEM FUND covers overhead costs and allows for 100% of all donor contributions to the Bay Area Lyme Foundation to go directly to research and prevention programs.

Hypersensitivity reactions may manifest as severe intraocular inflammation WARNINGS AND PRECAUTIONS Endophthalmitis and Retinal Detachments: Intravitreal injections, including those with ranibizumab products, have been associated with endophthalmitis and retinal detachments. Proper aseptic injection technique should always be utilized when administering CIMERLI®. Patients should be monitored following the injection to permit early treatment, should an infection occur Increases in Intraocular Pressure: Increases in intraocular pressure (IOP) have been noted both pre-injection and post-injection (at 60 minutes) with ranibizumab products. Monitor intraocular pressure prior to and following intravitreal injection with CIMERLI® and manage appropriately Thromboembolic Events: Although there was a low rate of arterial thromboembolic events (ATEs) observed in the ranibizumab clinical trials, there is a potential risk of ATEs following intravitreal use of VEGF inhibitors. ATEs are defined as nonfatal stroke, nonfatal myocardial infarction, or vascular death (including deaths of unknown cause) Neovascular (wet) age-related macular degeneration The ATE rate in the 3 controlled neovascular AMD studies during the first year was 1.9% (17 of 874) in the combined group of patients treated with 0.3 mg or 0.5 mg ranibizumab compared with 1.1% (5 of 441) in patients from the control arms. In the second year of Studies AMD-1 and AMD-2, the ATE rate was 2.6% (19 of 721) in the combined group of ranibizumab-treated patients compared with 2.9% (10 of 344) in patients from the control arms. In Study AMD-4, the ATE rates observed in the 0.5 mg arms during the first and second year were similar to rates observed in Studies AMD-1, AMD-2, and AMD-3 In a pooled analysis of 2-year controlled studies (AMD-1, AMD-2, and a study of ranibizumab used adjunctively with verteporfin photodynamic therapy), the stroke rate (including both ischemic and hemorrhagic stroke) was 2.7% (13 of 484) in patients treated with 0.5 mg ranibizumab compared to 1.1% (5 of 435) in patients in the control arms (odds ratio 2.2 [95% confidence interval (0.8-7.1)]) Macular edema following retinal vein occlusion The ATE rate in the 2 controlled RVO studies during the first 6 months was 0.8% in both the ranibizumab and control arms of the studies (4 of 525 in the combined group of patients treated with 0.3 mg or 0.5 mg ranibizumab and 2 of 260 in the control arms). The stroke rate was 0.2% (1 of 525) in the combined group of ranibizumab-treated patients compared to 0.4% (1 of 260) in the control arms Diabetic macular edema and Diabetic Retinopathy In a pooled analysis of Studies D-1 and D-2, the ATE rate at 2 years was 7.2% (18 of 250) with 0.5 mg ranibizumab, 5.6% (14 of 250) with 0.3 mg ranibizumab, and 5.2% (13 of 250) with control. The stroke rate at 2 years was 3.2% (8 of 250) with 0.5 mg ranibizumab, 1.2% (3 of 250) with 0.3 mg ranibizumab, and 1.6% (4 of 250) with control. At 3 years, the ATE rate was 10.4% (26 of 249) with 0.5 mg ranibizumab and 10.8% (27 of 250) with 0.3 mg ranibizumab; the stroke rate was 4.8% (12 of 249) with 0.5 mg ranibizumab and 2.0% (5 of 250) with 0.3 mg ranibizumab Fatal events in patients with diabetic macular edema and diabetic retinopathy at baseline: A pooled analysis of Studies D-1 and D-2 showed that fatalities in the first 2 years occurred in 4.4% (11 of 250) of patients treated with 0.5 mg ranibizumab, in 2.8% (7 of 250) of patients treated with 0.3 mg ranibizumab, and in 1.2% (3 of 250) of control patients. Over 3 years, fatalities occurred in 6.4% (16 of 249) of patients treated with 0.5 mg ranibizumab and in 4.4% (11 of 250) of patients treated with 0.3 mg ranibizumab. Although the rate of fatal events was low and included causes of death typical of patients with advanced diabetic complications, a potential relationship between these events and intravitreal use of VEGF inhibitors cannot be excluded ADVERSE REACTIONS Serious adverse events related to the injection procedure have occurred in <0.1% of intravitreal injections, including endophthalmitis, rhegmatogenous retinal detachment, and iatrogenic traumatic cataract In ranibizumab-treated patients compared with the control group, the most common ocular side effects included conjunctival hemorrhage, eye pain, vitreous floaters, and intraocular pressure. The most common non-ocular side effects included nasopharyngitis, anemia, nausea, and cough As with all therapeutic proteins, there is the potential for an immune response in patients treated with ranibizumab products. The clinical significance of immunoreactivity to ranibizumab products is unclear at this time Postmarketing Experience The following adverse reaction has been identified during post-approval use of ranibizumab products: Ocular: Tear of retinal pigment epithelium among patients with neovascular AMD *An interchangeable product (IP) is a biological product that is approved based on data demonstrating that it is highly similar to an FDA-approved reference product (RP) and that there are no clinically meaningful differences between the products; it can be expected to produce the same clinical result as the RP in any given patient; and if administered more than once to a patient, the risk in terms of safety or diminished efficacy from alternating or switching between use of the RP and IP is not greater than that from the RP without such alternation or switch.

ATEs are defined as nonfatal stroke, nonfatal myocardial infarction, or vascular death (including deaths of unknown cause) Neovascular (wet) age-related macular degeneration The ATE rate in the 3 controlled neovascular AMD studies during the first year was 1.9% (17 of 874) in the combined group of patients treated with 0.3 mg or 0.5 mg ranibizumab compared with 1.1% (5 of 441) in patients from the control arms. In the second year of Studies AMD-1 and AMD-2, the ATE rate was 2.6% (19 of 721) in the combined group of ranibizumab-treated patients compared with 2.9% (10 of 344) in patients from the control arms. In Study AMD-4, the ATE rates observed in the 0.5 mg arms during the first and second year were similar to rates observed in Studies AMD-1, AMD-2, and AMD-3 In a pooled analysis of 2-year controlled studies (AMD-1, AMD-2, and a study of ranibizumab used adjunctively with verteporfin photodynamic therapy), the stroke rate (including both ischemic and hemorrhagic stroke) was 2.7% (13 of 484) in patients treated with 0.5 mg ranibizumab compared to 1.1% (5 of 435) in patients in the control arms (odds ratio 2.2 [95% confidence interval (0.8-7.1)]) Macular edema following retinal vein occlusion The ATE rate in the 2 controlled RVO studies during the first 6 months was 0.8% in both the ranibizumab and control arms of the studies (4 of 525 in the combined group of patients treated with 0.3 mg or 0.5 mg ranibizumab and 2 of 260 in the control arms). The stroke rate was 0.2% (1 of 525) in the combined group of ranibizumab-treated patients compared to 0.4% (1 of 260) in the control arms Diabetic macular edema and Diabetic Retinopathy In a pooled analysis of Studies D-1 and D-2, the ATE rate at 2 years was 7.2% (18 of 250) with 0.5 mg ranibizumab, 5.6% (14 of 250) with 0.3 mg ranibizumab, and 5.2% (13 of 250) with control. The stroke rate at 2 years was 3.2% (8 of 250) with 0.5 mg ranibizumab, 1.2% (3 of 250) with 0.3 mg ranibizumab, and 1.6% (4 of 250) with control. At 3 years, the ATE rate was 10.4% (26 of 249) with 0.5 mg ranibizumab and 10.8% (27 of 250) with 0.3 mg ranibizumab; the stroke rate was 4.8% (12 of 249) with 0.5 mg ranibizumab and 2.0% (5 of 250) with 0.3 mg ranibizumab Fatal events in patients with diabetic macular edema and diabetic retinopathy at baseline: A pooled analysis of Studies D-1 and D-2 showed that fatalities in the first 2 years occurred in 4.4% (11 of 250) of patients treated with 0.5 mg ranibizumab, in 2.8% (7 of 250) of patients treated with 0.3 mg ranibizumab, and in 1.2% (3 of 250) of control patients. Over 3 years, fatalities occurred in 6.4% (16 of 249) of patients treated with 0.5 mg ranibizumab and in 4.4% (11 of 250) of patients treated with 0.3 mg ranibizumab. Although the rate of fatal events was low and included causes of death typical of patients with advanced diabetic complications, a potential relationship between these events and intravitreal use of VEGF inhibitors cannot be excluded ADVERSE REACTIONS Serious adverse events related to the injection procedure have occurred in <0.1% of intravitreal injections, including endophthalmitis, rhegmatogenous retinal detachment, and iatrogenic traumatic cataract In ranibizumab-treated patients compared with the control group, the most common ocular side effects included conjunctival hemorrhage, eye pain, vitreous floaters, and intraocular pressure. The most common non-ocular side effects included nasopharyngitis, anemia, nausea, and cough As with all therapeutic proteins, there is the potential for an immune response in patients treated with ranibizumab products. The clinical significance of immunoreactivity to ranibizumab products is unclear at this time Postmarketing Experience The following adverse reaction has been identified during post-approval use of ranibizumab products: Ocular: Tear of retinal pigment epithelium among patients with neovascular AMD *An interchangeable product (IP) is a biological product that is approved based on data demonstrating that it is highly similar to an FDA-approved reference product (RP) and that there are no clinically meaningful differences between the products; it can be expected to produce the same clinical result as the RP in any given patient; and if administered more than once to a patient, the risk in terms of safety or diminished efficacy from alternating or switching between use of the RP and IP is not greater than that from the RP without such alternation or switch. Interchangeability of CIMERLI® has been demonstrated for the condition(s) of use, strength(s), dosage form(s), and route(s) of administration described in its Full Prescribing Information. To report SUSPECTED ADVERSE REACTIONS, contact Coherus BioSciences, Inc. at 1-800-483-3692 or FDA at 1-800-FDA-1088 or .
