Abstract
Background:Risankizumab (RZB) is a humanized immunoglobulin G1 monoclonal antibody that specifically inhibits interleukin 23 by binding to its p19 subunit. RZB is being investigated as a treatment for adults with psoriatic arthritis (PsA).Objectives:To compare the efficacy and safety of RZB vs placebo (PBO) for the treatment of active PsA in patients who have had inadequate response or intolerance to ≥ 1 conventional synthetic disease modifying antirheumatic drug (csDMARD-IR).Methods:In KEEPsAKE 1 (NCT03675308), eligible adults (csDMARD-IR with ≥ 5 swollen joints [SJC] and ≥ 5 tender joints [TJC]) were randomized (1:1) to receive blinded subcutaneous RZB 150 mg or PBO at weeks 0, 4, and 16. The primary endpoint was the proportion of patients achieving 20% improvement in American College of Rheumatology score (ACR20) at week 24. Ranked secondary and other secondary endpoints are shown in the Table 1. Safety was assessed throughout the study. Results reported here are from the 24-week double-blind period; the open-label period with all patients receiving RZB is ongoing.Results:964 patients (RZB, N = 483; PBO, N = 481) were evaluated at week 24. Demographics and baseline characteristics were generally balanced between treatment groups (mean duration of PsA: 7.12 years; mean SJC: 12.2; mean TJC: 20.6; mean body surface area involved with psoriasis [BSA] in patients with BSA ≥ 3%: 16.7%). A significantly greater proportion of RZB- vs PBO-treated patients (57.3% and 33.5%, respectively) achieved the primary endpoint of ACR20 at week 24 (P < .001; Table 1). Significant differences were also observed for RZB vs PBO for the first 8 ranked secondary endpoints (P < .001 for all; Table 1). Serious adverse events were reported for 2.5% and 3.7% of RZB- and PBO-treated patients, respectively; serious infections were reported for 1.0% and 1.2%. There was 1 death in the RZB group.Conclusion:RZB resulted in significantly greater improvements in signs and symptoms of PsA compared with PBO and was well tolerated in patients who were csDMARD-IR.Disclosure of Interests:Lars Erik Kristensen Speakers bureau: LK has received honoraria or fees for serving as a speaker or consultant from AbbVie, Amgen, Biogen, Bristol-Myers Squibb, Gilead, Janssen, Lilly, Merck, Novartis, Pfizer, and UCB., Consultant of: LK has received honoraria or fees for serving as a speaker or consultant from AbbVie, Amgen, Biogen, Bristol-Myers Squibb, Gilead, Janssen, Lilly, Merck, Novartis, Pfizer, and UCB., MAURO KEISERMAN Speakers bureau: MK has received honoraria or fees for serving on advisory boards, as a speaker or as a consultant, and grants as a principal investigator from AbbVie, Amgen, Bristol-Myers Squibb, Celgene, GlaxoSmithKline, Janssen, Novartis, Pfizer, Roche, and UCB., Consultant of: MK has received honoraria or fees for serving on advisory boards, as a speaker or as a consultant, and grants as a principal investigator from AbbVie, Amgen, Bristol-Myers Squibb, Celgene, GlaxoSmithKline, Janssen, Novartis, Pfizer, Roche, and UCB., Grant/research support from: MK has received honoraria or fees for serving on advisory boards, as a speaker or as a consultant, and grants as a principal investigator from AbbVie, Amgen, Bristol-Myers Squibb, Celgene, GlaxoSmithKline, Janssen, Novartis, Pfizer, Roche, and UCB., Kim Papp Speakers bureau: KP has received honoraria or fees for serving on advisory boards, as a speaker, and as a consultant, as well as grants as principal investigator from AbbVie, Amgen, Astellas, Bausch Health (Valeant), Baxalta, Baxter, Boehringer Ingelheim, Bristol-Myers Squibb, Celgene, Coherus, Dermira, EMD Serono, Forward Pharma, Galderma, Genentech, GlaxoSmithKline, Janssen, Kyowa Kirin, LEO Pharma, Lilly, MedImmune, Merck, Novartis, Pfizer, Regeneron, Roche, Sanofi Genzyme, Stiefel, Sun Pharma, Takeda, and UCB., Consultant of: KP has received honoraria or fees for serving on advisory boards, as a speaker, and as a consultant, as well as grants as principal investigator from AbbVie, Amgen, Astellas, Bausch Health (Valeant), Baxalta, Baxter, Boehringer Ingelheim, Bristol-Myers Squibb, Celgene, Coherus, Dermira, EMD Serono, Forward Pharma, Galderma, Genentech, GlaxoSmithKline, Janssen, Kyowa Kirin, LEO Pharma, Lilly, MedImmune, Merck, Novartis, Pfizer, Regeneron, Roche, Sanofi Genzyme, Stiefel, Sun Pharma, Takeda, and UCB., Grant/research support from: KP has received honoraria or fees for serving on advisory boards, as a speaker, and as a consultant, as well as grants as principal investigator from AbbVie, Amgen, Astellas, Bausch Health (Valeant), Baxalta, Baxter, Boehringer Ingelheim, Bristol-Myers Squibb, Celgene, Coherus, Dermira, EMD Serono, Forward Pharma, Galderma, Genentech, GlaxoSmithKline, Janssen, Kyowa Kirin, LEO Pharma, Lilly, MedImmune, Merck, Novartis, Pfizer, Regeneron, Roche, Sanofi Genzyme, Stiefel, Sun Pharma, Takeda, and UCB., Leslie McCasland Speakers bureau: LM has received fees for serving on an advisory board from Lilly., Douglas White Speakers bureau: DW has received honoraria or fees for serving on advisory boards, as a speaker, and as a consultant from AbbVie, Merck, Novartis, and Roche., Consultant of: DW has received honoraria or fees for serving on advisory boards, as a speaker, and as a consultant from AbbVie, Merck, Novartis, and Roche., Lisa Barcomb Shareholder of: LB is a full-time employee of AbbVie, and may hold AbbVie stock or stock options., Employee of: LB is a full-time employee of AbbVie, and may hold AbbVie stock or stock options., Wenjing Lu Shareholder of: WL is a full-time employee of AbbVie, and may hold AbbVie stock or stock options., Employee of: WL is a full-time employee of AbbVie, and may hold AbbVie stock or stock options., Zailong Wang Shareholder of: ZE is a full-time employee of AbbVie, and may hold AbbVie stock or stock options., Employee of: ZE is a full-time employee of AbbVie, and may hold AbbVie stock or stock options., Ahmed M.

Abstract
With the rapid development of industrialization and urbanization in China, energy and vehicle consumption have continued to increase in recent years and air pollution has become serious. In early 2020, Corona Virus Disease 2019 broke out in Wuhan, China. From January 29, 2020, several sources of the air pollution almost all stopped working, including gasoline burning vehicles, dust producing building sites, coal-fired factories, etc. Five indicators of the atmospheric environmental quality were observed from December 19, 2019 to April 30, 2020 in nine cities and 1-h average concentrations, 24-h average concentrations and Air Quality Index were assessed. The 1-h average concentrations of the nitrogen dioxide, the ozone and the sulfur dioxide showed obvious difference though the closure did not change the sequence of the five pollutants' concentrations in the air at diverse sampling moments. The changing of the 24-h average concentrations of the five pollutants indicated the amount of pollutants in the air were greatly affected by human activities. The nitrogen dioxide, the sulfur dioxide and the particulate matters decreased obviously in the closure. The air in the metropolis and the south-east cities were relatively clean and the pollutants' concentrations decreased slightly during the closure period. The northern and the heavy industrial cities showed significant drop on air pollution indicators and the air quality of the two city groups could be greatly improved if some effective measures could be taken of environmental management and regional development.

Abstract
A high-temperature oven based on the inductive heating technology was developed successfully at the Institute of Modern Physics in 2019. This oven features a durable operation temperature of over 2000 °C inside the tantalum susceptor. By carefully designing the oven structure, the material compatibility issue at high temperature has been successfully solved, which enables the production and routine operation of refractory metal ions with SECRAL-II (Superconducting Electron Cyclotron Resonance ion source with Advanced design in Lanzhou No. 2). To further apply this type of oven to the room temperature ECR ion sources LECR4 and LECR5 (Lanzhou Electron Cyclotron Resonance ion source No. 4 and 5), a mini-inductive heating oven has been fabricated and tested in 2020. By directly evaporating calcium oxide, some high charge state calcium beams have been produced successfully, such as 52 euA of 40Ca16+, 30 euA of 40Ca17+, and 12 euA of 40Ca18+. The detailed design and testing results will be presented and discussed.

Abstract
OBJECTIVE The aim of this study was to explore the association between the expression of adenosine monophosphate-activated protein kinase (AMPK) pathway and adiponectin (APN), leptin, and vascular endothelial function in rats with coronary heart disease (CHD). MATERIALS AND METHODS Experimental rats were divided into three groups, including: control (Col) group, CHD model (CHD) group, and CHD+AMPK activator (CHD+AICAR) group. Except those in Col group, all rats were fed with high-fat diet and intraperitoneally injected with pituitrin to establish the CHD model. The levels of serum APN, leptin, and endothelin-1 (ET-1) were determined via enzyme-linked immunosorbent assay (ELISA). The content of serum nitric oxide (NO) was detected using the nitrate reductase method. Meanwhile, the expression of AMPK pathway-related protein AMPKα in vascular endothelial tissues was detected via Western blotting (WB). Aortic vascular endothelial cells (VECs) were cultured with AICAR or ET-1 in vitro. Subsequently, the expressions of AMPK pathway and protein kinase B (AKT) pathway-related proteins were determined through co-immunoprecipitation and WB. Moreover, the expression level of NO in VECs was determined using the DAF-FM DA fluorescence probe. RESULTS Compared with Col group, CHD group showed significantly decreased levels of serum APN and NO (p<0.05), significantly increased the levels of leptin and ET-1 (p<0.05), as well as remarkably decreased protein expression of p-AMPKα in vascular endothelial tissues (p<0.05). After injection of AMPK activator AICAR (200 mg/kg), the protein expression of p-AMPKα in CHD rats was significantly activated (p<0.05). The levels of serum APN and NO were remarkably upregulated (p<0.05), while the levels of leptin and ET-1 were significantly reduced (p<0.05). Besides, AICAR could evidently activate the activity of AMPK pathway in VECs in vitro, upregulate the protein levels of p-eNOS (Ser1177) and p-AMPKα, and promote the secretion of NO (p<0.05). In addition, AICAR remarkably inhibited ET-1-induced expression of AKT pathway (p<0.05). CONCLUSIONS Activating the AMPK pathway may play a positive role in the normal function of VECs and exert a certain curative effect on CHD in rats.

Abstract
CASES Three patients with knee-level complex regional pain syndrome type 1 (CRPS1), recalcitrant to conservative interventions, elected for transfemoral amputation and osseointegration. Two patients gained independent ambulation; the third remains on crutches after a disrupted sciatic nerve targeted reinnervation. One uses no pain medication, one is weaning off, and one requires a reduced regimen after revision nerve innervation. CONCLUSION Osseointegration seems suitable to optimize rehabilitation after amputation for CRPS1.

Abstract
We present results from the SPring-8 Angstrom Compact free electron LAser facility, where we used a high intensity (∼10^{20} W/cm^{2}) x-ray pump x-ray probe scheme to observe changes in the ionic structure of silicon induced by x-ray heating of the electrons. By avoiding Laue spots in the scattering signal from a single crystalline sample, we observe a rapid rise in diffuse scattering and a transition to a disordered, liquidlike state with a structure significantly different from liquid silicon. The disordering occurs within 100 fs of irradiation, a timescale that agrees well with first principles simulations, and is faster than that predicted by purely inertial behavior, suggesting that both the phase change and disordered state reached are dominated by Coulomb forces. This method is capable of observing liquid scattering without masking signal from the ambient solid, allowing the liquid structure to be measured throughout and beyond the phase change.

Abstract
Objective: To evaluate the consistency of different measurement methods of saliva 1,5-anhydroglucitol (1,5-AG) in different glucose metabolism populations. Methods: From January 2018 to June 2019, 175 healthy volunteers (21-65 years, 58 males and 117 females) with normal glucose tolerance (NGT) and 80 diabetic patients (18-70 years, 44 males and 36 females) were enrolled in Shanghai Jiao Tong University Affiliated Sixth People's Hospital. Saliva was collected by saliva collection tube, and 1,5-AG was measured using both enzymatic and mass spectrometry methods. Serum 1,5-AG was determined by enzymatic method. Results: In NGT subjects, both serum and saliva 1,5-AG levels detected by enzymatic method were positively correlated with the saliva 1,5-AG levels detected by liquid chromatography-mass spectrometry (r=0.247 and 0.523, respectively, both P<0.05). However, there was no significant correlation between saliva and serum 1,5-AG levels detected by enzymatic method (r=-0.074, P=0.333). In diabetic patients, both serum and saliva 1,5-AG levels detected by enzymatic method were positively correlated with the saliva 1,5-AG levels detected by gas chromatography-mass spectrometry (r=0.284 and 0.423, respectively, both P<0.05). However, there was no significant correlation between saliva and serum 1,5-AG levels detected by enzymatic method (r=-0.079, P=0.487). Conclusions: Both serum and saliva 1,5-AG levels detected by enzymatic method have a good consistency with saliva 1,5-AG levels detected by mass spectrometry method. The saliva and serum 1,5-AG levels detected by enzymatic method are not well correlated, and thus the enzymatic detection of saliva 1,5-AG needs further improvement in clinical practice.

Abstract
Abstract
Introduction/Objective
Transfusion of blood components is one of the most common medical procedures with transfusion reactions being the greatest associated risk. Acute pain transfusion reaction (APTR) is one such under- recognized and under-reported risk, likely due to scarcity of literature and lack of criteria for diagnosis.
Methods
A literature review was performed using PubMed to search for the keywords: “acute pain transfusion reaction”. This searched revealed two articles, from which one abstract and a book chapter were also identified.
Results
A 58-year-old female with chronic myeloid leukemia and pre-existing pain received 44 leukoreduced irradiated blood components [7 pooled platelets, 17 apheresis platelets, 20 red blood cells (RBCs)] over two months. Four platelet (one pooled, three apheresis) transfusions resulted in chest and lower back pain starting an average of 15 minutes after initiation of transfusion and resolving following cessation of transfusion. Laboratory evaluations were negative for hemolysis. Despite the patient’s history of pain, these reactions were most consistent with APTRs.
APTRs are rare, most often associated with leukoreduced RBCs and characterized by severe pain in the abdomen, back, flank, or proximal extremities typically occurring within 30 minutes of starting transfusion and abating within 30 minutes following cessation of transfusion. All of our patient’s reported reactions occurred in association with leukoreduced platelets. These reactions may be associated with the leukoreduction, but reports of APTR appeared when leukoreduction became standard practice. Therefore, the etiology remains unknown.
Conclusion
This case aids in the argument that APTR is a complication of transfusion, despite the absence of a clear etiology or diagnostic criteria. Additional research and improved surveillance are necessary to elucidate potential etiology and improve patient care by identifying prevention and treatment options. A diagnostic criterion would aid efforts to harmonize reporting in the United States and collect the hemovigilance data required to improve transfusion outcomes.

Abstract
Objective: To investigate the appropriate cut-off point of time in range (TIR) for evaluating glucose control in type 2 diabetes mellitus (T2DM) patients, and analyze the prevalence of abnormal carotid intima-media thickness (CIMT) and diabetic retinopathy (DR) in different TIR categories. Methods: A total of 2 161 subjects with T2DM (1 183 males) were enrolled from hospitalized patients at the Department of Endocrinology and Metabolism of the Sixth People's Hospital Affiliated to Shanghai Jiao Tong University from January 2005 to February 2012. The age of the enrolled participants was (60.4±11.9) years. Each patient underwent continuous glucose monitoring (CGM) for three consecutive days, then TIR (3.9-10.0 mmol/L), time above range (TAR) and time below range (TBR) were calculated. Fundus photography and carotid artery Doppler ultrasound were performed to diagnose DR and abnormal CIMT (defined as CIMT≥1.0 mm), respectively. Multivariate logistic regression models were used to examine the independent association of different TIR groups with CIMT and DR. Results: All subjects were divided into 4 groups according to TIR:≤40%, 41%-70%, 71%-85% and>85%. Significant linear trends in age, diabetes duration, body mass index (BMI), total cholesterol, glycated hemoglobin A1c (HbA1c), TAR and mean glucose (MG) existed among the 4 groups (all P(trend)<0.05). However, there was only a weak correlation between TIR and TBR (<3.9 mmol/L) (r=0.087, P<0.001), and no significant association was observed between TBR (<3 mmol/L) and the TIR categories (P(trend)=0.378). The overall prevalence of abnormal CIMT and DR was 12.1% and 23.8%, respectively. The prevalence of abnormal CIMT in the 4 groups with ascending levels of TIR was 16.9% (59/349), 12.9% (96/746), 11.2% (57/510) and 9.0% (50/556) (P(trend)<0.001), respectively. And the prevalence of DR was 30.7% (107/349), 29.4% (219/746), 20.8% (106/510) and 14.9% (83/556), respectively (P(trend)<0.001). In the binary logistic regression model by adjusting confounding factors, compared with TIR≤ 40%, the risk of abnormal CIMT was reduced by 33.8% (OR=0.662, 95%CI: 0.456-0.963, P=0.031), 40.8% (OR=0.592, 95%CI: 0.390-0.899, P=0.014), and 45.0% (OR=0.550, 95%CI: 0.358-0.846, P=0.006) in the other three groups, respectively. And the risk of DR was reduced by 2.9% (OR=0.971, 95%CI: 0.725-1.301, P=0.844), 33.4%(OR=0.666, 95%CI: 0.479-0.924, P=0.015) and 53.3% (OR=0.467, 95%CI: 0.331-0.657, P<0.001), respectively. Conclusion: Using 40%, 70% and 85% as cut-off point of TIR helps stratify the risk of diabetic complications, and assess the glucose control (Poor: TIR≤40%; Unsatisfactory: TIR≤70%; Satisfactory: TIR>70%; Optimal: TIR>85%) in patients with T2DM.

Abstract
OBJECTIVE Bladder cancer is considered as the fifth most common cancer in the whole world. This study aimed to investigate the anti-tumor effects of Nanoscale bubbles delivered yeast cytosine deaminase thymidine kinase/connexin 26 (YCD-TK/Cx26) on tumor cell proliferation and tumor growth. MATERIALS AND METHODS Nanoscale bubble was prepared using thin-film hydration-sonication method. Nanoscale bubble-LV5-YCD-TK+PCD-Cx26 was generated and transfected into BIU-87 cells. MTT assay was employed to detect cell viability. Apoptosis was determined using a flow cytometry assay. YCD-TK and Cx26 expressions were detected using Western blot and Real Time-PCR (RT-PCR). BIU-87 cells were transplanted into mice to establish Xenograft models. The tumor volume was recorded. HE staining was used to examine necrosis areas in tumor tissues. RESULTS Nanoscale bubble (Nanoscale bubble-LV5-YCD-TK+PCD-Cx26) successfully mediated YCD-TK and Cx26 gene expression in BIU-87 cells. Nanoscale bubble delivered YCD-TK/Cx26 expression significantly inhibited cell viability and induced apoptosis compared to Nanoscale bubble-LV5-YCD-TK and Nanoscale bubble group (p<0.05). Nanoscale bubble delivered YCD-TK/Cx26 expression triggered significantly higher levels of bystander effect compared to single YCD-TK or single Cx26 gene (p<0.05). Nanoscale bubble delivered YCD-TK/Cx26 expression significantly reduced tumor volume in mouse Xenograft bladder cancer model compared to LV5-YCD-TK and 5-FC+GCV group (p<0.05). Nanoscale bubble delivered YCD-TK/Cx26 expression significantly reduced the necrosis of tumor tissues in mouse Xenograft bladder cancer model compared to LV5-YCD-TK group and 5-FC+GCV group (p<0.05). CONCLUSIONS Nanoscale bubble delivered YCD-TK/Cx26 gene therapeutic system efficiently reduced BIU-87 cell proliferation in vitro, and suppressed tumor growth by inducing necrosis of tumor tissues in mouse Xenograft bladder cancer models.

Abstract
By engineering an anti-parity-time (anti-PT) symmetric cavity magnonics system with precise eigenspace controllability, we observe two different singularities in the same system. One type of singularity, the exceptional point (EP), is produced by tuning the magnon damping. Between two EPs, the maximal coherent superposition of photon and magnon states is robustly sustained by the preserved anti-PT symmetry. The other type of singularity, arising from the dissipative coupling of two antiresonances, is an unconventional bound state in the continuum (BIC). At the settings of BICs, the coupled system exhibits infinite discontinuities in the group delay. We find that both singularities coexist at the equator of the Bloch sphere, which reveals a unique hybrid state that simultaneously exhibits the maximal coherent superposition and slow light capability.

Abstract
The atmosphere contains an abundance of fresh water, but this resource has yet to be harvested efficiently. To date, passive atmospheric water sorbents have required a desorption step that relies on steady solar irradiation. Since the availability and intensity of solar radiation vary, these limit on-demand desorption and hence the amount of harvestable water. Here, we report a polymer-metal-organic framework that provides simultaneous and uninterrupted sorption and release of atmospheric water. The adaptable nature of the hydro-active polymer, and its hybridization with a metal-organic framework, enables enhanced sorption kinetics, water uptake, and spontaneous water oozing. We demonstrate continuous water delivery for 1440 hours, producing 6 g of fresh water per gram of sorbent at 90% relative humidity (RH) per day without active condensation. This leads to a total liquid delivery efficiency of 95% and an autonomous liquid delivery efficiency of 71%, the record among reported atmospheric water harvesters.

Abstract
OBJECTIVE To determine the protective effect of nicotinamide on chronic hypoxic myocardial cells and its underlying mechanism. MATERIALS AND METHODS The H9C2 cell lines were taken as objects of study, and were divided into blank group, hypoxia group and nicotinamide treatment group. The cell viability, apoptosis level, autophagy level and mammalian target of rapamycin (mTOR) pathway activity in each group were detected via Cell Counting Kit-8 (CCK8) assay, Hoechst staining, immunofluorescence staining, Polymerase Chain Reaction (PCR) and Western blotting, respectively. RESULTS Nicotinamide could protect the viability of normoxic and chronic hypoxic myocardial cells. Besides, it could also inhibit the expression of caspase3 messenger ribonucleic acid (mRNA) in chronic hypoxic myocardial cells, and reduce the expression of apoptosis-related proteins. Furthermore, it could induce the mRNA expression of autophagy-associated gene 5 (ATG5) and increase the expression of autophagy-related proteins. Further study on the mechanism of nicotinamide showed that nicotinamide could inhibit the activity of the mTOR pathway, thus regulating the autophagy. CONCLUSIONS Nicotinamide induces the autophagy of chronic hypoxic myocardial cells by regulating the mTOR pathway, thereby protecting cells from apoptosis.

Abstract
Acceleration of ultrathin foils by the laser radiation pressure promises a compact alternative to the conventional ion sources. Among the challenges on the way to practical realization, one fundamental is a strong transverse plasma instability, which develops density perturbations and breaks the acceleration. In this Letter, we develop a theoretical model supported by three-dimensional numerical simulations to explain the transverse instability growth from noise to wave breaking and its crucial effect on stopping the acceleration. The wave-broken nonlinear mode triggers rapid stochastic heating that finally explodes the target. Possible paths to mitigate this problem for getting efficient ion acceleration are discussed.

Abstract
Artificial insemination (AI) with frozen or cooled-stored semen plays a key role in the widespread distribution of germplasm of elite livestock resources and the protection of endangered species. Cryopreservation provides long-term preservation of sperm and also encourages a greater exchange of genetic material between distant populations. However, freezing has some detrimental effects on sperm, including premature induction of acrosome response, reduced sperm motility, reduced viability, and impaired sperm DNA integrity and fertility. The transition of the membrane phase occurs when the sperm cools down, and lipid accumulation damages the micro-domain, thereby impairing membrane functions, leaving a gap between the gel and the liquid membrane region. Coenzyme Q10 (CoQ10) is a vital lipophilic molecule found in all respiratory eukaryotic cells, including spermatozoa. When such a lipophilic antioxidant is added to the sperm, it can directly diffuse into the polyunsaturated lipid chain present in the plasma membrane, thereby affecting the structure and function of the sperm by generating energy and preventing reactive oxygen. Coenzyme Q10 treatment of sperm from various species improves sperm quality during cryopreservation and cooled-stored condition. It is, however, unclear how this antioxidant affects sperm to improve survival during freezing or cooled-stored condition. Thus, this review highlights the potential protective mechanisms of coenzyme Q10 action during the sperm freezing process.

Abstract
Abstract
Recent advances in gene editing have enabled the targeted engineering of primary cells to insert entire transgenes without the use of viral vectors. Using these methods, novel genes can be inserted in a seamless manner into the specified genomic locus, realizing the goal of precise targeted genomic modifications. Non-viral modification of primary cells holds potential to significantly reduce costs and time needed for the generation of therapeutic cell products. It has also allowed the generation of personalized cell therapies involving patient-specific manufacturing of DNA constructs, such as for the developed of patient-derived, neoepitope-specific TCR-T cells.
Proof-of-concept experiments have shown that non-viral genome engineering methods can integrate small genetic elements such as GFP, while the delivery of larger therapeutically relevant payloads at high efficiency has previously been challenging. Here we describe a proprietary single-step, DNA-mediated method developed for seamlessly engineering fully natural neoepitope-specific TCRs (neoTCR) into the endogenous TCR locus of primary human T cells at high efficiencies (i.e. >50% gene editing efficiency). This method allows the delivery of the two genes comprising the neoTCR without the need for selection necessitated by less efficient approaches.
To further evaluate this approach, fresh human donor T cells were engineered to express the patient-specific neoTCR plus two additional gene products, CD8α and CD8β (i.e. precise genome engineering of four ectopic genes). The data shows that these modifications were made at high efficiency, resulting in fully functional CD8 and CD4 T cells. Surface expression of CD8 coreceptor together with the neoE-targeted TCR increased T cell signaling sensitivity of the engineered neoTCR-T cells by 10-100 fold.
The potential for off-target cleavage or unexpected genomic outcomes was assessed using multiple methods, including a newly developed primary T cell GUIDE-seq assay. Despite multi-locus editing, no evidence of off-target insertion or unexpected genomic rearrangements were observed.
In summary, these results demonstrate the applicability of a single step, highly efficient method for manufacturing fresh human T cells into neoTCR-T cell therapies, engineered with multiple functionalities. This proprietary precision genome engineering technology supports the on-going Phase 1 clinical trial of personalized autologous, NeoTCR-P1 engineered T cell therapies for patients with solid tumors (NCT03970382).
