Abstract Background The management of COVID-19 in organ transplant recipients is among the most imperative, yet less discussed, issues based on their immunocompromised status along with their vast post-transplant medication regimens. No conclusive study has been published to evaluate proper anti-viral and immunomodulator medications effect in treating COVID-19 patients to this date. Method This retrospective study was conducted in Shiraz Transplant Hospital, Iran from March 2020 to May 2021 and included COVID-19 diagnosed patients based on SARS-CoV-2 RT-PCR positive test who had been hospitalized for at least 48 h before enrolling in the study. Clinical and demographic information of patients, along with their treatment course and the medication used were evaluated and analyzed using multiple regression analysis. Results A total of 245 patients with a mean age of 49.59 years were included with a mortality rate of 8.16%. The administration of Remdesivir as an anti-viral drug (P value < 0.001) and Tocilizumab as an immunomodulator drug (P value < 0.001) could reduce the hospitalization period in the hospital and the intensive care unit, as well as the mortality rates significantly. Meanwhile, the patients treated with Lopinavir/Ritonavir experienced a lower chance of survival (OR < 1, P value = 0.04). No significant difference was observed between various therapeutic regimens in clinical complications such as bacterial coinfections, cardiovascular and gastrointestinal adverse reactions, and liver or kidney dysfunctions. Conclusion The administration of Remdesivir as an anti-viral and Tocilizumab as an immunomodulatory drug in solid-organ transplant recipients could be promising treatments of choice to manage COVID-19.

Abstract Introduction: Patients with relapsed/refractory multiple myeloma (RRMM) resistant to multiple drug classes remain a high unmet need population, despite advances in MM patient care. The objective of this study was to assess real-world treatment patterns and outcomes in patients with RRMM who had failed multiple prior lines of therapy (LOT) and were refractory to multiple drug classes to identify gaps in their treatment pathways. Methods: This longitudinal retrospective cohort study utilized the COTA de-identified real-world database derived from US electronic health records of partnered healthcare providers from Q3 1988 through Q1 2020. Adults with active RRMM previously exposed to a proteasome inhibitor (PI) and an immunomodulatory drug and who received ≥3 prior LOTs were identified. Patients were further categorized as refractory to a PI and an immunomodulatory drug (double-class refractory [DCR]) or additionally to an anti-CD38 monoclonal antibody (i.e. daratumumab; triple-class refractory [TCR]). Determining refractory status was based on International Myeloma Working Group criteria. Index LOT was a new LOT after evidence of DCR or TCR status following ≥3 (DCR) or ≥4 (TCR) prior LOTs. Patient characteristics described included Eastern Cooperative Oncology Group (ECOG) performance status, International Staging System (ISS) stage, cytogenetic risk, age, index date, sex, and follow up time. Treatment pattern assessments included treatments received before/during/after index LOT, reasons for discontinuation, refractory status, and retreatment characteristics. Patient outcomes (overall survival [OS], duration of treatment [DOT], and time to next therapy [TTNT]) were analyzed using Kaplan-Meier survival analysis methods. Results: After excluding patients who were aged &lt;18 years at start of index LOT with no evidence of clinical activity and who participated in a clinical trial during index LOT, 381 (DCR) and 173 (TCR) patients were available for analysis. Median follow-up from index LOT initiation through end of data availability/death was 14 (DCR) and 8 (TCR) months. Demographic characteristics were consistent between DCR and TCR patients. Approximately half were aged ≥65 years (49% DCR; 53% TCR), majority had high-risk cytogenetics (56% DCR; 66% TCR) or prior autologous stem cell transplantation (&gt;62%), and 14-16% had ISS stage III. Patients had a median of 3 (DCR) and 6 (TCR) prior LOTs. Prior to index LOT, bortezomib and lenalidomide were the most commonly received PI and immunomodulatory drug (received by &gt;98% of DCR or TCR patients) and the most common PI and immunomodulatory drugs to which patients were refractory (71% and 84% DCR; 76% and 83% TCR, respectively). At index LOT, PI/immunomodulatory drug-based and daratumumab-based therapies remained the most common therapies. Bortezomib and lenalidomide had the longest time to refractory status and highest retreatment rates among DCR or TCR patients. Approximately 40% of TCR patients were retreated with daratumumab-based therapies after becoming refractory (Table). After index LOT, 70% of DCR and 58% of TCR patients continued to a subsequent LOT. Patients most frequently discontinued index LOT due to disease progression (59% DCR; 60% TCR), toxicity (23% DCR; 25% TCR), or doctor preference (14% DCR; 10% TCR). Median duration of gaps between LOTs generally were shorter than 1 month (Table). Median OS was 22.3 (DCR) and 11.6 (TCR) months. Median DOT was 3.3 (DCR) and 2.8 (TCR) months, and median TTNT was 4.1 (DCR) and 3.2 (TCR) months. In multivariate statistical analyses, inferior baseline ECOG performance scores, and high-risk cytogenetic abnormalities were associated with worse prognosis (higher risk of death, shorter DOT, and shorter TTNT) in DCR and TCR patients. Age was not a significant factor after adjusting for other baseline factors. Conclusions: Treatment options are limited for US patients with DCR and TCR RRMM. DCR and TCR patients were frequently retreated with a PI, an immunomodulatory drug, or daratumumab, despite refractoriness to these agents. Many DCR and TCR MM patients stopped active MM treatment after discontinuing index treatment. Patients with DCR and TCR MM have poor prognosis, especially among high cytogenetic risk and poor performance status patients. This study provides the benchmark for new therapies, like BCMA-targeted agents, to be tested in this population. Funding: GSK (Study 217353). Figure 1 Figure 1.

Abstract Background: Multiple myeloma (MM) is a hematological B-cell malignancy that remains incurable for most patients. Almost all patients, including those who initially respond to treatment, are expected to relapse and subsequently cycle through multiple lines of treatment. The addition of proteasome inhibitors, immunomodulatory drugs and monoclonal antibodies has improved patient outcomes; however, survival of patients after these agents is very poor and highlights an unmet medical need in the relapsed/refractory MM population. Elranatamab (PF-06863135) is a humanized bi-specific antibody that targets both BCMA-expressing MM cells and CD3-expressing T cells, with binding resulting in T-cell mediated cytotoxicity. Elranatamab preclinical studies have demonstrated anti-tumor activity and delayed tumor progression. A Phase 1 study, MagnetisMM-1 (ClinicalTrials.gov ID: NCT03269136), with the aim of characterizing the efficacy, safety, pharmacokinetics, and pharmacodynamics of elranatamab as single agent and in combination with immunomodulatory agents for patients with relapsed/refractory MM is ongoing. Study Design and Methods: MagnetisMM-3 is an open-label, multicenter, non-randomized, Phase 2 study to evaluate the efficacy and safety of elranatamab monotherapy in patients with relapsed/refractory MM who are refractory to at least one proteasome inhibitor, one immunomodulatory drug, and one anti-CD38 antibody (ClinicalTrials.gov ID: NCT04649359). Approximately 150 patients will be enrolled to one of two independent parallel cohorts: those naïve to BCMA-directed therapies (Cohort A) and those with previous exposure to BCMA-directed therapy (Cohort B). The primary endpoint is objective response rate, according to International Myeloma Working Group [IMWG] response criteria. Secondary endpoints include duration of response, cumulative complete response (CR) rate, duration of cumulative CR, progression-free survival, time to response, minimal residual disease negativity rate, overall survival, safety, plasma concentrations, and immunogenicity of elranatamab. Key inclusion criteria are age ≥18 years, MM diagnosis according to IMWG criteria and with measurable disease based on IMWG criteria as defined by at least 1 of the following: Serum M-protein ≥0.5 g/dL by SPEP, Urinary M-protein excretion ≥200 mg/24 hours by UPEP; Serum immunoglobulin free light chain ≥10 mg/dL (≥100 mg/L) and abnormal serum immunoglobulin kappa to lambda free light chain ratio (&lt;0.26 or &gt;1.65). Eligible patients should also have ECOG performance status ≤2, be refractory to at least one proteasome inhibitor, one immunomodulatory drug, and one anti-CD38 antibody and be relapsed/refractory to their last treatment regimen. Key exclusion criteria are smoldering MM, active plasma cell leukemia, amyloidosis, POEMS syndrome, active, uncontrolled bacterial, fungal or viral infections, stem cell transplant within 12 weeks of enrollment, any other active malignancy within 3 years prior to enrollment (except for adequately treated basal cell or squamous cell skin cancer, or carcinoma in situ), or having received previous administration of an investigational drug within 30 days or 5 half-lives (whichever is longer) of the first dose of elranatamab. This study is, or is planned to be, open at centers in the USA, Australia, Canada, Belgium, France, Germany, Japan, Poland, Spain, and the UK.

Numerous treatment options are available for patients with early relapsed multiple myeloma. Clinicians should consider using a monoclonal antibody for patients who have not yet received one, or changing either the immunomodulatory drug, the proteasome inhibitor, or both. Clinical trials are another option, or clinicians can refer transplant-naïve patients for autologous stem cell transplantation (ASCT). For patients with late relapse, a clinical trial is recommended, if possible, but many patients are ineligible due to poor blood cell counts or other factors. Additional treatment options include selinexor combinations, belantamab mafodotin-blmf, melflufen, or CAR T-cell therapy. Salvage ASCT should also be considered for this challenging population.

Abstract Vaccination is a primary way to prevent infectious disease in poultry. The quality of immune response depends on the immune status of the body which, in turn, depends on many endogenous and exogenous factors. This study analyzed the effect of the immunomodulatory drug Azoxivet on the immune response in laying hens after vaccination against Newcastle Disease and Infectious Bursal Disease. There were 4 groups of Loman White cross laying hens (n=20). At age 120 days, all hens habitated in individual cages with an area of 0,15 m2. The conditions of keeping and feeding matched breed requirements. All groups were vaccinated against Newcastle Disease (NDV) (LaSota strain) and Infectious Bursal Disease (IBD) (Winterfield 2512 strain). All groups received Azoxivet (Az) at a dose of 0,3 mg/kg in water three times daily. Blood sera were collected weekly for serological studies using BioChek IBD and NDV test systems. The antibody level of all hens before and after vaccination: 1378 (IBD+Az) vs. 1674,93 (IBD) (P &lt; 0,05), 5194,75 (NDV+Az) vs. 5612,87 (NDV) (P &lt; 0,05). After one week of vaccination: 5931,25 (IBD+Az) vs. 5006,14 (IBD) (P &lt; 0,05), 6207,58 (NDV+Az) vs. 5765,21 (NDV) (P &lt; 0,05). Two weeks: 11086,00 (IBD+Az) vs. 10485,83 (IBD) (P &lt; 0,05), 11255,25 (NDV+Az) vs. 8478,75 (NDV) (P &lt; 0,05). Three weeks: 11478 (IBD+Az) vs. 8286 (IBD) (P &lt; 0,05), 14725 (NDV+Az) vs. 12677 (NDV) (P &lt; 0,05). Four weeks: 12999 (IBD+Az) vs. 1009,67 (IBD) (P &lt; 0,05), 17399 (NDV+Az) vs. 16373,17 (NDV) (P &lt; 0,05). Five weeks: 13601,15 (IBD+Az) vs. 9021,30 (IBD) (P &lt; 0,05), 19671 (NDV+Az) vs. 16309 (NDV) (P &lt; 0,05). Thus, Azaxul had a positive influence on the post-vaccination immune response in laying hens when used after Newcastle Disease and Infectious Bursal Disease vaccines. The results of the study can be used to improve disease prevention in poultry farming.

Background: Immunomodulatory drugs have been used in patients with severe COVID-19. The objective of this study was to evaluate the effects of two different strategies, based either on an interleukin-1 inhibitor, anakinra, or on a JAK inhibitor, such as baricitinib, on the survival of patients hospitalized with COVID-19 pneumonia. Methods: Individuals admitted to two hospitals because of COVID-19 were included if they fulfilled the clinical, radiological, and laboratory criteria for moderate-to-severe disease. Patients were classified according to the first immunomodulatory drug prescribed: anakinra or baricitinib. All subjects were concomitantly treated with corticosteroids, in addition to standard care. The main outcomes were the need for invasive mechanical ventilation (IMV) and in-hospital death. Statistical analysis included propensity score matching and Cox regression model. Results: The study subjects included 125 and 217 individuals in the anakinra and baricitinib groups, respectively. IMV was required in 13 (10.4%) and 10 (4.6%) patients, respectively (p = 0.039). During this period, 22 (17.6%) and 36 (16.6%) individuals died in both groups (p = 0.811). Older age, low functional status, high comorbidity, need for IMV, elevated lactate dehydrogenase, and use of a high flow of oxygen at initially were found to be associated with worse clinical outcomes. No differences according to the immunomodulatory therapy used were observed. For most of the deceased individuals, early interruption of anakinra or baricitinib had occurred at the time of their admission to the intensive care unit. Conclusions: Similar mortality is observed in patients treated with anakinra or baricitinib plus corticosteroids.

Nitric oxide (NO), as a free radical, is produced by inflamed microglia cells and is one of the destructive factors of the immune system and a factor in myelin degradation. Therefore, inhibition of microglia activity is a chief strategy in reducing neurotoxic damage to the central nervous system. In this study, an herbal Immunomodulatory Drug (IMOD) was used to evaluate the effects of this drug in controlling the amount of nitric oxide. Nitric oxide induction was performed by bacterial lipopolysaccharide (LPS) in rat inflamed microglial cell line, CHME-5. ELISA test was used to measure the produced nitric oxide at 24, 48, and 72 hours. The results showed that the high concentrations of IMOD (1.2, and 4% V/V) had anti-inflammatory effects on microglial cells and were able to reduce the amount of nitric oxide in these cells but the effective dose of IMOD was in the range of 1.2% V/V. Therefore, the safest dose and the best time for the effect of IMOD on inflammatory cell groups are 1.2% V/V and 72h, respectively. Hence, with further studies, IMOD can be considered as an herbal anti-inflammatory drug that is effective in controlling neurodegenerative diseases.
