93. Non-clinical in vitro evaluation of antibiotic resistance gene-free plasmids encoding human or murine IL-12 intended for first-in-human clinical studyŠpela Kos, Maša Omerzel, Tanja Jesenko, Boštjan Markelc, Urška Kamenšek, Katarina Žnidar, Urška Matkovič, Andrej Renčelj, Gregor Serša, Rosana Hudej, Aneja Tuljak, Matjaž Peterka, Maja Čemažar, 2021, original scientific article Abstract: Interleukin 12 (IL-12) is a key cytokine that mediates antitumor activity of immune cells. To fulfill its clinical potential, the development is focused on localized delivery systems, such as gene electrotransfer, which can provide localized delivery of IL-12 to the tumor microenvironment. Gene electrotransfer of the plasmid encoding human IL-12 is already in clinical trials in USA, demonstrating positive results in the treatment of melanoma patients. To comply with EU regulatory requirements for clinical application, which recommend the use of antibiotic resistance gene-free plasmids, we constructed and developed the production process for the clinical grade quality antibiotic resistance gene-free plasmid encoding human IL-12 (p21-hIL-12-ORT) and its ortholog encoding murine IL-12 (p21-mIL-12-ORT). To demonstrate the suitability of the p21-hIL-12-ORT or p21-mIL-12-ORT plasmid for the first-in-human clinical trial, the biological activity of the expressed transgene, its level of expression and plasmid copy number were determined in vitro in the human squamous cell carcinoma cell line FaDu and the murine colon carcinoma cell line CT26. The results of the non-clinical evaluation in vitro set the basis for further in vivo testing and evaluation of antitumor activity of therapeutic molecules in murine models as well as provide crucial data for further clinical trials of the constructed antibiotic resistance gene-free plasmid in humans.

94. Vismodegib in locally advanced basal cell carcinoma in SloveniaTanja Mesti, Maša Sever, Janja Ocvirk, 2022, original scientific article Abstract: Background: Vismodegib is a first-in-class inhibitor of the hedgehog pathway for treatment of locally advanced basal cell carcinoma (laBCC) and metastatic BCC. Objectives: The purpose of this study is to report outcomes of patients with laBCC, with basal cell carcinoma nevus syndrome (Gorlin Goltz syndrome [G-G Syn]) treated with vismodegib in routine clinical practice in Slovenia in 8.3-year period. Methods: In this retrospective cohort study, we analyzed baseline characteristics, outcomes, and treatment-related adverse events from locally advanced BCC. The patients were divided into two cohorts: 39 laBCC or multiple BCC patients and 7 patients with G-G Syn who were treated with vismodegib from November 2012 till January 2021. Results: During 100-month period, 46 patients were diagnosed with laBCC (26), multiple BCC (13), and G-G Syn (7), all inappropriate for surgery or radiotherapy. Baseline characteristics: median age was 72.8 years in laBCC + multiple BCC cohort and 47.4 years in G-G Syn cohort. The objective response rate was 80% in laBCC + multiple BCC and 86% in G-G Syn cohort. Disease control rate (DCR) was 95% in laBCC + multiple BCC and 100% in G-G Syn cohort. Median duration of treatment was 9.9 months (range: 1.5-43.1) in laBCC and multiple BCC cohort and 19.5 months (range: 3.6-94.1) in G-G Syn cohort. Majority of treatment-emergent adverse events (TEAEs) in laBCC or multiple BCC cohort were grade 1 or 2 (96%), only 4% of AEs were grade 3. Majority of TEAEs in G-G Syn cohort were also grade 1 or 2 (87%), 13% of AEs were grade 3. No grade 4 or 5 vismodegib-related AEs were reported. Conclusion: Vismodegib has shown meaningful efficacy with DCR from 95% to 100% in patients with laBCC, multiple BCC, and G-G Syn in Slovenia. TEAEs were successfully alleviated with multidisciplinary approach and early supportive care.

96. In vitro and in vivo correlation of skin and cellular responses to nucleic acid deliveryMaša Omerzel, Katarina Žnidar, A. Sales Conniff, Tanja Jesenko, Boštjan Markelc, Jared Tur, Nina Semenova, Kristopher Kohena, Simona Kranjc Brezar, Loree C. Heller, Maja Čemažar, 2022, original scientific article Abstract: Skin, the largest organ in the body, provides a passive physical barrier against infection and contains elements of the innate and adaptive immune systems. Skin consists of various cells, including keratinocytes, fibroblasts, endothelial cells and immune cells. This diversity of cell types could be important to gene therapies because DNA transfection could elicit different responses in different cell types. Previously, we observed the upregulation and activation of cytosolic DNA sensing pathways in several non-tumor and tumor cell types as well in tumors after the electroporation (electrotransfer) of plasmid DNA (pDNA). Based on this research and the innate immuno- genicity of skin, we correlated the effects of pDNA electrotransfer to fibroblasts and keratinocytes to mouse skin using reverse transcription real-time PCR (RT-qPCR) and several types of protein quantification. After pDNA electrotransfer, the mRNAs of the putative DNA sensors DEAD (AspGlu-Ala-Asp) box polypeptide 60 (Ddx60), absent in melanoma 2 (Aim2), Z-DNA binding protein 1 (Zbp1), interferon activated gene 202 (Ifi202), and interferon-inducible protein 204 (Ifi204) were upregulated in keratinocytes, while Ddx60, Zbp1 and Ifi204 were upregulated in fibroblasts. Increased levels of the mRNAs and proteins of several cytokines and chemokines were detected and varied based on cell type. Mouse skin experiments in vivo confirmed our in vitro results with increased expression of putative DNA sensor mRNAs and of the mRNAs and proteins of several cytokines and chemokines.

99. Epidemiology and risk factors of self-reported systemic allergic reactions to a Hymenoptera venom in beekeepers worldwide : a protocol for a systematic review of observational studiesTanja Carli, Igor Locatelli, Mitja Košnik, Andreja Kukec, 2022, review article Abstract: Introduction Systemic allergic reaction (SAR) to a Hymenoptera venom is a potentially life-threatening disorder. The rate of SAR between beekeepers in comparison with a healthy individual is different. The risk for an SAR is particularly high in beekeepers due to their persistent or seasonal exposure to the stinging Hymenoptera. We aim to provide a critical appraisal and a synthesis of evidence-based data from epidemiological observational studies, focusing on SARs to a Hymenoptera venom and the associated risk factors for SARs in beekeepers worldwide. Methods and analysis Searching will include seven electronic databases for published studies without language restrictions, from inception up to 3 August 2021, and it will be rerun for all electronic databases prior publication. Only epidemiological observational studies in beekeepers will be included. The risk of bias in the included studies will be appraised by using the Joanna Briggs Institute Critical Appraisal Checklist for Analytical Cross-Sectional Studies and the Newcastle-Ottawa Scale, adapted for cross-sectional studies. For the certainty of evidence, the Grading of Recommendations Assessment, Development and Evaluation approach will be used. Qualitative synthesis will be presented in a tabulated format with the selected characteristics across primary studies and the main outcome of interest. A meta-analysis is planned to be performed if there will be a sufficient number of homogeneous studies with complete data. The Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols 2015 statement will guide the reporting of this systematic literature review. Ethics and dissemination No ethics approval is needed to conduct the systematic literature review since it will be solely based on the published literature. Findings will be disseminated through the relevant conferences, peer-review and open-access journals.
Keywords: systemic allergic reaction (SAR), Hymenoptera venom, systematic literature review
