NCT07440290
This clinical trial is looking at two drugs called dabrafenib and trametinib. Dabrafenib and trametinib are approved as standard of care treatment for adult patients with melanoma (a type of skin cancer) or lung cancer and in children with glioma (a type of brain tumour). This means they have gone through clinical trials and been approved by the Medicines and Healthcare products Regulatory Agency (MHRA) in the UK. Dabrafenib and trametinib work in patients with a particular mutation in their cancer known as BRAF V600. Investigators now wish to find out if they will be useful in treating patients with other cancer types which have the same mutation. If the results are positive, the study team will work with the NHS and the Cancer Drugs Fund to see if these drugs can be routinely accessed for patients in the future. This trial is part of a trial programme called DETERMINE. The programme will also look at other anti-cancer drugs in the same way, through matching the drug to rare cancer types or ones with specific mutations.
NCT07410676
This Phase 1/2 study evaluates the safety, tolerability, and preliminary anti-tumor activity of EBNK-001 (allogeneic NK cells) given after lymphodepleting cyclophosphamide/fludarabine (CY/FLU) and supported with low-dose IL-15, administered either alone or in combination with pembrolizumab in adults with advanced/metastatic solid tumors. The study will determine a recommended Phase 2 dose (RP2D) and explore signals of clinical activity using RECIST-based response criteria.
NCT07361666
Non-melanoma skin cancers (NMSC), particularly basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC), are the most common malignancies in Caucasians, with the majority of tumors located in the head and neck due to chronic ultraviolet exposure. Although BCC has very low metastatic potential, while cSCC carries a higher risk of nodal spread, both can cause significant local tissue destruction and functional and cosmetic impairment. Complete excision with histologically clear margins remains the standard treatment; however, incomplete or close excision margins are reported in a substantial proportion of cases and are associated with increased risk of local recurrence, need for additional treatment, and higher healthcare costs. Preoperative dermoscopy improves delineation of lateral tumor borders but does not assess depth of invasion. High-frequency ultrasound (HFUS) is a rapid, non-invasive imaging modality that can visualize superficial skin structures and estimate tumor thickness. Previous studies have suggested good agreement between HFUS and histopathologic depth of invasion, but results are not fully consistent, and HFUS has not yet been incorporated into major guideline recommendations for preoperative assessment of NMSC. Further prospective data are needed to clarify whether HFUS can improve surgical planning and margin control. This prospective study is designed to assess the impact of adding preoperative HFUS to standard dermoscopic evaluation in head and neck BCC and cSCC. The primary objectives are: (1) to compare the frequency of positive or inadequate (\<1 mm) histopathologic excision margins between lesions assessed with dermoscopy alone and those assessed with both dermoscopy and HFUS; and (2) to evaluate 5-year local recurrence rates in relation to preoperative assessment method, histopathologic margin status, and subsequent management of inadequate margins (observation, non-surgical treatment, or scar excision). Secondary and additional objectives include: assessing concordance between HFUS-measured and histopathologic depth of invasion; determining the frequency of residual tumor in scars excised after inadequate margins; evaluating recurrence rate according to the site of inadequate margins (lateral vs deep); and identifying patient-related, tumor-related, surgical, and histopathologic predictors of inadequate margins and recurrence. Approximately 400 lesions (BCC or cSCC of the head and neck) qualified for curative surgical excision will be included. Each lesion will constitute an independent study case. All lesions will undergo preoperative assessment, including clinical evaluation with detailed medical history and dermoscopy; in one cohort, lesions will additionally be evaluated with HFUS. HFUS will be performed with an 18-MHz linear probe, using superficial B-mode and color Doppler. Maximum tumor depth will be recorded from the epidermal surface (or granular layer) to the deepest hypoechoic point, with assessment of potential infiltration of deeper structures when visible. Surgical excision and postoperative care will follow standard clinical practice. Postoperative histopathologic assessment of FFPE tumor samples will record tumor histologic type and subtype, margin status, width, depth of invasion, differentiation, inflammation, elastosis, perineural or vascular invasion, and other routinely assessed diagnostic features. In the event of positive or inadequate excision margins, patients will be referred, after consultation with a dermatologist, for further management (observation, non-surgical treatment, or scar excision), depending on clinical indications and patient preferences. Participation in the study will not influence the primary surgical treatment or any decisions regarding subsequent management. Patients will be followed for at least 5 years according to current clinical guidelines, with dermoscopic skin examination and documentation of local recurrence and its management. The study aims to determine whether incorporating HFUS into preoperative assessment can reduce the frequency of inadequate histologic margins and improve long-term local control in head and neck NMSC.
NCT02636569
This research study will test how well one topical medications work to prevent the development of non-melanoma skin cancers by reversing certain biomarkers in the skin. This study is also looking at the optimal dose of a medication in a small number of people. Biomarkers are molecules that are found in the body and inside of cells. Some biomarkers are associated with specific diseases such as skin cancer. In this study, one topical medication will be evaluated; diclofenac. Diclofenac and is approved by the Food and Drug Administration (FDA) for other uses. 24 patients will be enrolled in this study by University of Alabama at Birmingham.
NCT07347392
The goal of this observational study is to learn about the long-term effects of radiotherapy for people who were treated for non-melanoma skin cancer (NMSC) in the head and neck area. The study focuses on adults who finished radiotherapy at least two years ago. The main questions we aim to answer are: How satisfied are participants with the cosmetic result of their treatment? What skin changes do healthcare professionals observe at the treated area? How many participants have experienced a recurrence or developed a new skin cancer, since treatment? Participants will be invited to: Attend one extra hospital visit at least two years after they finished radiotherapy Answer a short questionnaire about their cosmetic satisfaction Have their skin examined, including photos and dermatoscopy The results may help improve future treatment guidelines for people with non-melanoma skin cancer.professional, and any local recurrences will be identified through national health registries. This nationwide study (DOSCA-2) will provide real-world data to help guide future treatment recommendations for NMSC.
NCT04091022
This is a single institution, randomized, placebo-controlled, double-blind phase IIB trial of 1) topical diclofenac and topical DFMO, or 2) placebo in participants with a history of non melanoma skin cancer/ keratinocytic cancers.
NCT04844528
This is a randomized, phase II, double-blind, placebo-controlled trial with planned crossover to the intervention arm after 1 year. Consenting patients with CLL who have had at least one NMSC diagnosed in the past year will be randomized to receive either oral nicotinamide 500 mg twice daily (BID) for 1 year or oral placebo 1 tablet twice daily for 1 year. Patients will be stratified according to CLL therapy and the number of prior NMSC. At the end of 1 year, patients will undergo dermatologic examination and the number of new NMSC will be quantified. The number of patients who develop new NMSC in each arm will be documented. At this time, patients will be unblinded and all patients will receive Nicotinamide 500 mg BID for an additional year. At the end of this second year, patients will again undergo dermatologic examination, and the number of new NMSC will be quantified. The number of patients who develop NMSC will be documented. Skin biopsies will be taken for correlative studies. Enrollment will be split into two parts separated by an interim analysis. Part 1 will accrue 40 patients: 20 to each arm. After 40 patients have completed their 12 month visit an interim futility analysis will be conducted prior to recruiting more patients. The study will stop if the difference in the number of patients with NMSC between control and treatment arms is 0 or less (i.e., absolutely no evidence that the treatment is better than control). If the trial is not stopped, the investigators will proceed with Part 2 and recruit 46 more patients.
NCT03906253
This study is following up on previous studies that have demonstrated that geriatric subjects respond different to ultraviolet B (UVB) light than young subjects. The treatment of geriatric skin with dermal rejuvenation therapies (dermabrasion, fractionated laser resurfacing) restores the appropriate UVB response. Ongoing studies have tested the ability of fractionated laser resurfacing (FLR) to assess how long this wounding effect lasts-and have found that this appears to be a durable response which lasts for at least two years. The findings that FLR protects geriatric skin at two years is the impetus for this study. This study is an interventional study to assess if FLR treatment of one forearm of geriatric subjects with multiple actinic keratosis will result in the short-term removal of actinic keratosis, and the long-term decrease in levels of future actinic keratosis and other non-melanoma skin cancers in comparison to the untreated arm. Study length and visit: The first part of the study is completed in 1 day then there are follow up visits at 90 days and every 6 months for 5 years.
NCT05955924
As patients live longer after receiving an organ transplant, there is a need to reduce the long-term side effects of the drugs used to prevent organ rejection. In particular, long-term use of these drugs increases the risk of skin cancer. Skin cancer is now a leading cause of illness and disfigurement after kidney, liver, heart, and lung transplantation. Given the increased risk and burden of skin cancer in transplant recipients, prevention is critical. Nicotinamide is a form of Vitamin B3 that has been shown to protect against skin cancer in the general population. However, it is unclear whether nicotinamide is effective among immune-suppressed transplant recipients. Investigators will conduct a clinical trial involving multiple transplant centres in Canada to evaluate whether oral nicotinamide (500 mg twice daily) is effective and safe for preventing skin cancer. Investigators will recruit 396 high-risk adult kidney, liver, heart, and lung transplant patients who have previously had at least one skin cancer. Patients will receive nicotinamide or sham tablets for up to 4 years. The results will inform efforts to improve the long-term health of transplant recipients.
NCT04160065
In this clinical phase I, non-randomized, open-label, uncontrolled, interventional, multi-center trial, 20 adult subjects (≥ 18 years of age) with advanced non-melanoma skin cancers will receive a fixed dose of 0.1 mg of IFx-Hu2.0 intralesionally as monotherapy in up to three lesions at up to three time points. Subjects will be observed for any acute adverse events (AEs) post injection and for any delayed AEs at Day 28, 35 and/or 42 ± 7 days, depending on the cohort (exposure escalation and expansion design).
NCT03327064
This is a randomized, double-blind, placebo-controlled biomarker study in renal transplant recipients with actinic damage and a history of basal cell carcinomas and/or cutaneous squamous cell carcinomas. There will be two arms to the study: 1) daily oral UAB30 for 28 days; and 2) daily oral placebo for 28 days. The total duration of the study is anticipated to be 5 years. The hypothesis being tested is that a significantly greater percentage of subjects randomized to oral UAB30 over a period of 28 days will achieve ≥30% reduction in biomarkers of proliferation and ≥30% increase in apoptosis biomarkers than those who receive placebo. Cyclin D1 will serve as the primary biomarker. This investigation will determine whether subjects randomized to UAB30 have an increase in all trans-retinoic acid responsive genes in the skin compared to those receiving placebo. This will include an examination of target effects of UAB30 by evaluating its effects in vivo in humans on the DNA damage response and Src signaling pathways.
NCT06523816
The main aim of the study is to investigate the relation between dermoscopic findings in pre-operative diagnosis of non-melanocytic skin tumors and post-operative histopathology findings .
NCT06428721
The purpose of this study is to determine if the Fractionated Laser Resurfacing (FLR) procedure can protect one forearm/wrist from precancerous actinic keratosis (AKs) as well as prevent skin cancer in older subjects with active AKs. This study builds on a similar study ongoing at the Dayton Veterans Administration dermatology clinic. This study is also testing if a photograph of the skin can be used to predict where the AKs and an skin cancers will form.
NCT03110159
This is a pilot, phase 2, prospective, comparative study to evaluate the safety and efficacy of the combination of Levulan® Kerastick® for Topical Solution and blue light illumination using the BLU-U® Blue Light Photodynamic Therapy Illuminator (LevulanPDT). The study hypothesis is that post solid organ transplantation patients, highly susceptible to non-melanoma skin cancer, can be treated safely and effectively through clinical cyclic application of PDT, lessening morbidity and possible mortality for this immunosuppressed patient population.
NCT03246412
The study investigates if a computer-based clinical decision support tool for skin cancer may improve the diagnostic accuracy of general practitioners (GPs). The aim of the program is to help GPs increase their diagnostic accuracy, in particular regarding the selection of suspicious skin lesions that need biopsy or referral to specialist health care for further assessment. Half of the physicians in the trial will have the clinical decision support tool available during consultations, while the other half has no such tool available. We hypothesize that general practitioners using the clinical decision support tool will have a higher number of correct classifications of skin lesions compared to doctors without the tool.
NCT05932511
Randomized comparative trial of a 30% solution of ascorbic acid in 95% dimethylsulfoxide applied topically twice a day for 8 weeks vs 5% imiquimod cream in the treatment of biopsy proven squamous cell carcinomas of the skin in otherwise healthy adult patients. Outcome measure was biopsy proven resolution of the carcinoma.

ONCR-177-101 is a phase 1, open-label, multi-center, dose escalation and expansion study of ONCR-177, an oncolytic Herpes Simplex Virus for intratumoral injection, alone and in combination with PD-1 blockade in adult subjects with advanced and/or refractory cutaneous, subcutaneous or metastatic nodal solid tumors or with Liver Metastases of Solid Tumors. The purpose of this study is to determine the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D), as well as to evaluate preliminary efficacy.
NCT05842421
Prospective, unicentric study that examines if imaging devices like total body photography, dermoscopy, optical coherence tomography and in vivo reflectance confocal microscopy as an addition to clinical examination lead to a benefit for patients in the diagnosis of non-melanoma skin cancer and their precursors
NCT00392561
The purpose of this study is to evaluate whether selenium and/or vitamin E are effective in preventing non-melanoma skin cancers.
NCT03769285
A common long-term side effect of anti-rejection (immunosuppressant) medications is skin cancer. This pilot clinical trial evaluates the feasibility of conducting a larger pivotal trial to examine the efficacy and safety of nicotinamide for prevention of keratinocyte carcinoma in solid organ transplant recipients. This pilot trial will transition into the pivotal trial if all feasibility targets are met.
