A New 222nm-Illuminator for the Suppression of Airborne Viral Epidemic Spread

The Covid-19 epidemic has been the most consequential global health crisis since the era of the influenza pandemic of 1918 [1]. Due to its high spreading rate, the virus disseminated across the world in a very short time span, forcing the World Health Organization to declare Covid-19 a global pandemic after just 3 months from the first reported case in China. At the beginning of the pandemic, when no vaccines were available, people entrust their safety to very few devices such as personal protective equipment (face masks, shields, and gloves), lock-down, and social distancing. The lack of alternative and not conventional techniques to suppress the spread of airborne epidemics among humans has pushed the research to develop new antiviral devices. The SAVE-US project (Suppression of Airborne Viral Epidemic Spread by UV-Light Barriers) aims at developing and demonstrating an innovative antimicrobial device based on 222nm-radiation. As known from the literature, the UVC radiation (200-280 nm) is the most effective wavelength for the inactivation of viruses and bacteria, corresponding to the DNA and RNA absorption peaks, but may also be mutagenic. For this reason, UVC-light sterilization is commonly performed in the absence of living organisms. Radiation in the far-UVC, especially at 222 nm, has been recently investigated because it shows a good antimicrobial efficacy, tested already on both bacteria [2] and virus [3] models including coronavirus, with very limited risks to human health. The low risk is associated to the small penetration depth of 222 nm light (a few mum): the energy is absorbed by the superficial stratum corneum of the skin that contains dead cells, with negligible irradiation of the underlying live tissue [4]. We will present the first version of a new prototype of 222 nm-illuminator and some preliminary results on its characterization;the presented device will be used in successive in vitro and in vivo experiments with SARS-CoV-2 virus. The device embeds a far-UVC lamp emitting at 222 nm, optical filters, and the controlling electronics. We show results on the spatial homogeneity of the emission intensity and the dependence on the lamp-virus distance. We also report on the ozone production due to absorption of far-UVC light from molecular oxygen naturally present in the air in order to evaluate its safety for human being and to properly evaluate its photo-killing efficacy.Copyright © 2023

SAVES US: Suppression of Airborne Viral Epidemic Spread by Ultraviolet light barriers

Despite the gradual return to pre-pandemic conditions, the spreading of COVID-19 (SARS-CoV-2) left several open issues. Nowadays it is know that airborne infections, including COVID-19, are conveyed by particles having the size of >5 mum (droplets) and <5 mum (droplets nuclei), ejected by coughing and sneezing [1]. While droplets undergo to dehydration and precipitation, droplet nuclei persist in air for long time after their ejection, contributing to infection spreading. Actual prevention strategies are based on non-pharmaceutical interventions act to reduce droplets diffusion and spacing from Personal Protective Equipment, such as facial masks, and social distancing measure. Nevertheless, for the new endemic phase of COVID-19 the development of new strategies for airborne infections' containment becomes unavoidable. In this project, we propose a new device for the suppression of Airborne Viral Aerosols designed to work in situations with constrained geometries (e.g. public transportation, offices, waiting rooms etc.) not allowing social distancing. The device, devised to perform photokilling of viral aerosols in air in presence of humans, has its core in an UV illumination system operating at 222 nm. It is know from literature that UV radiation alters the genetic material of viruses and bacteria whose maximum absorption wavelengths are in the far-UV range (UVC, 100-280 nm), the most effective for sterilization [2]. Differently from the operative wavelength of most commercial systems (254 nm), the higher tissue absorption prevents the 222 nm radiation to travel over the very first epidermal layers [3] constituting a minor health risk for applications in presence of people. The device combines the UV illumination system with a vertical flux of air that conveys exhaled particles to the light source and controls humidity and temperature, crucial parameters for virus diffusion. After its development, the device prototype will be tested in model experiments. Initially, its safety will be verified by monitoring in particular the UVC-induced ozone production. Then, in vitro photokilling experiments will be performed in two steps: (i) on a layer of immobilized SARS-Cov-2 virus act to obtain optimal UV doses for an effective sterilization;(ii) on SARS-Cov-2 aerosol models. For this last experiment, a model viral aerosol miming the characteristics of cough and sneeze particles will be preliminary studied and supported by synthetic data to characterize the optical properties of the reference scenario. The resulting information will be crucial for the final design of the device itself. As a last step, we will test the device in in vivo experiments. An air flux, harvesting exhaled air by infected mice, will be illuminated by the device and will be sent to healthy mice. Finally, the infectiveness of exhaled air after the UV treatment will be evaluated, providing more information for further applications in the presence of humans.Copyright © 2023

Directed evolution of human Adenoviruses to improve vectored vaccines properties

Replication incompetent human Adeno (hAd)-based vectors are able to induce potent adaptive immune responses in animal models and humans, being of interest for both infectious diseases and cancer therapy or prevention. Different Adenovirus-based vaccines have been approved for human use, including those developed to contrast Covid-19 pandemic. Immunological potency of hAdvectors based on different serotypes can be influenced by the extent of pre-existing host immunity, different cell tropism and intracellular trafficking, also impacting the extent of innate immunity induction. Vaccines based on species C hAd are among the most potent, yet significant seroprevalence in humans limits their application into the clinic, with pre-existing neutralizing antibodies negatively affecting vectored vaccine immunogenicity and efficacy. Error prone PCR represents an efficient method to introduce random mutations by reducing the DNA polymerase fidelity, allowing directed evolution and improvement of target proteins. Since the majority of hAd neutralization determinants are located in the hypervariable regions (HVR) of the hexon, the major capsid protein, we generated seven different hexon-variant libraries with mutations in single or multiple HVRs from Group C hAd, through error prone PCR. Such libraries have been used to produce complex repertoires of hAd vectors potentially including variants with novel properties such as lower recognition by anti-hAd antibodies present in humans or reduced unwanted side effects in the vaccinees. These libraries will be surveyed with different screening strategies to identify novel variants with improved properties for both prophylactic and therapeutic vaccine applications.

Net treatment benefit of OSE2101 in HLA-A2+ non-small cell lung cancer (NSCLC) patients after failure to immune checkpoint inhibitors (IO) in phase III Atalante-1 randomized trial

Background: OSE2101 (Tedopi) is an anticancer vaccine that increased overall survival (OS) (HR 0.59, p=0.017) versus Standard of Care Chemotherapy in the population of interest (PoI N=118) of patients with IO secondary resistance after sequential CT-IO (ESMO 2021 #47LBA). The Net Treatment Benefit (NTB) is an original method combining efficacy and safety endpoints to test the overall improvement in health outcome between 2 treatments (Buyse M. Stat Med 2010). NTB was assessed in the overall population (N=219) from whom OS improvement of OSE2101 (HR 0.86, p=0.35) was lower than in PoI. Methods: NTB was tested by comparing prioritized outcomes using Generalized Paired Wise Comparisons (GPC). The prioritized outcomes were OS, then time to worsening ECOG (threshold=2 months) followed by severe adverse events, progression free survival (shorter vs. longer than 2 months) and Quality of Life (threshold=5 points on Global Health Status of EORTC-QLQC30). Analysis was stratified using the 3 strata of the study (histology, best response to 1rst line, line of prior IO) and enrollment time (before vs during COVID-19). Sensitivity analyses used no stratification, different thresholds of clinical relevance and PoI. Results: In the primary analysis (1088 pairs), NTB was 19% and reached statistical significance in favor of OSE2101 (p=0.035). In unstratified analysis (11120 pairs), NTB was 11% (p=0.188). In the PoI (388 pairs), NTB was 22% (p stratified=0.074) and 28% (p=0.014) in unstratified analysis (3040 pairs). Although the primary analysis was statistically positive, results were not consistent in some sensitivity analyses due to the limited sample size and the impact of stratification factors. Conclusions: An overall improvement in health outcome was observed with OSE2101 in the overall population of advanced NSCLC after IO failure with a NTB of 19% over SoC. In PoI with IO secondary resistance after CT-IO, the NTB was 22%. Post-hoc analyses are ongoing intended to explain the variability of NTB and will be detailed.

DE NOVO DOUBLE GLOMERULOPATHY (MEMBRANOUS NEPHROPATHY, MN AND COLLAPSING FOCAL SEGMENTAL GLOMERULOSCLEROSIS, CFSGS) ASSOCIATED TO POSITIVE MYELOPEROXIDASE-O (MPO) ANTIBODY FOLLOWING PFIZER - BIONTECH MRNA VACCINATION COVID 19

BACKGROUND AND AIMS: In the COVID 19 pandemic era, anti SARS-CoV-2 vaccination showed high efficacy at preventing the infection and its most severe complications. The aim of this report is to describe an unusual double glomerulopathy related to anti SARS-CoV-2 vaccination and the good results obtained with the immunosoppressive treatment. METHOD: An 80-year-old caucasian woman developed a nephrotic syndrome, progressive renal insufficiency and microhematuria. The patient presented a medical history of thrombocytopenic purpura treated and resolved by steroids in 2013, hypothyroidism, hypertension, ischaemic heart disease treated with surgical bypass in 2019 and pacemaker in 2020 for atrial ventricular block. Due to pandemic COVID 19 status, she received two doses of the Pfizer BioNTech mRNA COVID-19 vaccine in March 2021. Two weeks after the second dose her weight increased of 23 kg. The family physician added furosemide to her therapy for generalized edema with no diuretic effect. In April, creatinine was 1.38 mg/dL (versus 0.8 mg/dL 1 year before);urinalysis showed proteinuria (300 mg/dL) and microscopic hematuria;serum total cholesterol level was 218 mg/dL and triglycerides 178 mg/dL;then it was suggested to increase the doses of furosemide. In May 2021, creatinine resulted 2 mg/dL, serum albumin 2 g/dL, and urinalysis confirmed proteinuria and microscopic hematuria;proteinuria was 10 g/day. Abdomen ultrasound showed normal liver, kidneys and spleen, not ascites. Lower limb eco-Doppler showed right superficial femoral artery stenosis of 60% and absence of venous thrombosis. The physical examination evidenced anasarca. The patients were admitted to the nephrology unit;hepatitis B surface antigen, hepatitis C antibody and human immunodeficiency virus antigen and antibody were negative. Both complement C3 and C4 levels resulted within the normal range. Cryoglobulins were absent. Urinary Bence Jones, antinuclear antibody (ANA), anti-extractable nuclear antigen (ENA), anti-double stranded DNA (nDNA) antibodies were negative. Antineutrophil cytoplasm antibodies (ANCA) were 1:2560 with Perinuclear pattern and anti-MPO positivity (716 UA/mL);anti-proteinase-3 antibodies (PR3) were negative. Antiphosholipase A2 receptor antibody (PLA2R Ab) was positive with high titre. A kidney biopsy was performed showing a double nephropathy: a focal segmental glomerulosclerosis (FSGS) with some collapsing features, superimposed on membranous glomerulonephritis (Fig. 1). RESULTS: We started the Ponticelli regimen (alternate months steroids and cyclophosphamide). After the first month of therapy, blood tests revealed creatinine 1.7 mg/dL, haemoglobin 11.7 g/dL;serum albumin 2.7 g/dL and urinalysis without microscopic haematuria. At the third month of therapy, the patient developed atrial fibrillation and started anticoagulation;blood tests were as follows: creatinine 1.1 mg/dL, serum albumin 3.0 g/dL, Ab anti-MPO 7 UA/mL and PLA2R Ab was absent. A left ocular, frontal and parietal herpes zoster induced a short discontinuation of therapy and responded well to Acyclovir;then we concluded the fourth month of therapy. At the fifth month, a SARS CoV 2 RT PCR unexpectedly resulted positive;the patient remained asymptomatic, but we stopped definitively the therapy. One month later, blood tests showed: creatinine 1 mg/dL, serum albumin 4 g/dL, proteinuria 0.7 g/die, MPO 2 UA/mL and PLA2R Ab absent. CONCLUSION: To our knowledge, this is the first case of nephrotic sindrome secondary to a De novo MN and FSGS, associated with positive MPO antibody, following Pfizer-BioNTech mRNA vaccination COVID 19;the patient responded well to immunosoppression going in remission and regaining renal function.

LBA47 Activity of OSE-2101 in HLA-A2+ non-small cell lung cancer (NSCLC) patients after failure to immune checkpoint inhibitors (IO): Final results of phase III Atalante-1 randomised trial

Background: OSE2101 (Tedopi®) is an anticancer vaccine (modified epitopes restricted to HLA-A2+ from 5 tumor-associated antigens). Atalante-1 is a randomized phase 3 trial of OSE2101 vs Standard of Care (SoC docetaxel or pemetrexed) in pretreated HLA-A2+ patients with advanced NSCLC, with IO as last treatment. Methods: EGFR and ALK negative NSCLC patients, ECOG PS 0-1 were randomized 2:1 to receive OSE2101 subcutaneously Q3W for 6 cycles, followed by maintenance Q8W for 1 year and Q12W until progression, versus SoC (docetaxel or pemetrexed Q3W). Primary endpoint was OS (initial hypothesis of HR 0.7 for 401 pts). Secondary endpoints were disease control rate (DCR), quality of life (QoL - EORTC QLQ-C30/LC13), and Progression free survival (PFS). Toxicities were reported using CTCAE 5.0. Positive pre-specified analyses (ESMO 2020 #1260MO) identified a Population of Interest (PoI) comprised by patients with IO secondary resistance defined as failure after a minimum of 12 weeks IO in sequential CT-IO patients. Due to the risk of COVID-19 pandemic on data integrity, the study was stopped prematurely following IDMC recommendations. PoI was chosen as primary population for the final analysis. Results: 219 pts were enrolled: median age 65 years, 29% female, 10% never-smoker, 70% non-squamous. 183 (84%) pts received sequential CT-IO from whom 118 pts (54%) complied with the definition of PoI, with otherwise similar characteristics that the overall population. In PoI, mOS was 11.1 mo for OSE2101 vs 7.5 for SoC [HR 0.59 (0.38-0.91) p= 0.02]. 6 mo-DCR 25% vs 24% (NS), mPFS 2.7 mo vs 3.4 (NS), ORR 8% vs 18% (p=0.07). Post progression survival was 7.7 mo vs 4.6 [HR 0.46 p= 0.004], time to worsening ECOG PS 8.6 mo vs 3.3 [HR 0.45 p= 0.0005]. In the total population, HR for OS was 0.86 (0.62-1.19) p=0.36. QoL Global Health Status was maintained for OSE2101 (p<0.05). Severe Adverse Events were 38% vs 68% (p<0.001). There was no TEAE of concern in the OSE2101 group. Conclusions: OSE2101 had a favorable benefit/risk of versus SoC in advanced HLA-A2+ NSCLC patients. HR for OS improved from 0.86 to 0.59 in patients with secondary resistance to IO with a meaningful gain of median OS of 3.6 months with OSE2101.

Covid-19 laryngectomized patients care, on field experience, and considerations

Laryngectomized patients showed an unconventional response to SARS-CoV-2 viral infection. Here, we describe five different patient cases along with our interpretation of the phenomena and suggestions for their safe management.

Activity of OSE-2101 in HLA-A2+ non-small cell lung cancer (NSCLC) patients after failure to immune checkpoint inhibitors (ICI): Step 1 results of phase III ATALANTE-1 randomised trial

Background: Tedopi® is an anticancer vaccine with modified neoepitopes restricted to HLA-A2+ targeting five tumor-associated antigens frequently expressed in lung cancer: CEA, HER2, MAGE2, MAGE3 and P53. ATALANTE-1 was a randomized, open-label, 2-Step phase 3 study comparing the efficacy of Tedopi® with standard treatment (SoC) in HLA-A2+ NSCLC patients in 2nd or 3rd line treatment after progression on ICI. Methods: HLA-A2+ NSCLC patients, EGFR and ALK negative, having progressed to platinum-based chemotherapy (CT) and anti-PD(L)1, ECOG PS 0-1 were randomized 2:1 to receive Tedopi® subcutaneously Q3W for 6 cycles, followed by maintenance Q8W up to first year, then Q12W, or SoC (docetaxel 75 mg/m2 Q3W or pemetrexed 500 mg/m2 Q3W). The Step-1 hypotheses were based on the evaluation of 1y-OS rate (Fleming design: H0 futility boundary at 25%;H1 alternative efficacy: 40% of OS rate at 12 months). Step-2 was a superiority study with OS as primary endpoint. Results: At cutoff of February 2020, 99 patients (Tedopi® n=63;SoC n=36) were randomized and analyzable for Step-1. The 1y-OS was 29/63 (46%) [95%CI 33-59]) in Tedopi® group and 13/36 (36%) [95%CI 21-54] in SoC. The Step-1 endpoint has shown a lower limit of the 95% confidence interval above the futility boundary (25%) with an OS estimate of 10% above the estimate of SoC. Secondary endpoints and subgroup data will be further presented. Grade 3-4 related TEAEs were 11 % in Tedopi® group and 43 % in SoC. There was no related grade 5 TEAE. Related TEAE leading to withdrawal from the study were also less frequent in Tedopi® group (6%) versus SoC (14%). Due to the risk of COVID-19 pandemic on data integrity, following recommendation of the Independent Data Monitoring Committee and Steering Committee, the decision was taken to early terminate the study at Step-1 and definitely stop new accrual while continuing the OS follow-up in all patients. Conclusions: The Step-1 primary endpoint was positively achieved with a 1y-OS rate of 46% and a good safety profile. Step-1 results shown a favorable benefit/risk of Tedopi® over SoC as 2nd or 3rd line treatment in advanced HLA-A2+ NSCLC patients after failure to ICI.
