Introduction: Timing of clinical grading has not been fully studied in patients with aneurysmal subarachnoid hemorrhage (aSAH). Our primary objective was to identify at which time point the clinical assessment using the World Federation of Neurological Surgeons Scale (WFNS) and the Glasgow Coma Scale (GCS) is most predictive of poor functional outcome. Methods: Retrospective cohort study on the association of clinical grading determined at presentation, nadir and post-resuscitation, and poor outcome. Poor functional outcome was defined as Glasgow Outcome Scale score of 1-3 at 6 months. The study was approved by our Institutional Review Board. Results: We identified 186 consecutive patients admitted to a teaching hospital between January 2002 and June 2008. Patients’ mean age was 56.9±13.7 years and 63% of the patients were women. Twenty-four percent had poor functional outcome (mortality was 17%). On univariable logistic regression analyses, GCS determined at presentation (OR=0.80; p<0.0001), nadir (OR=0.73; p<0.0001) and post-resuscitation (OR=0.53; p<0.0001), modified Fisher Scale (OR=2.21;p=0.0013), WFNS assessed at presentation (OR=1.92;p<0.0001), nadir (OR=3.51; <0.0001) and post-resuscitation (OR=3.91; <0.0001), intracerebral hematoma on initial CT (OR=4.55;p<0.0002), acute hydrocephalus (OR=2.29;p=0.0375), and cerebral infarction (OR=4.84; <0.0001) were associated with poor outcome. On multivariable logistic regression analysis, only cerebral infarction (OR=5.80; 0.0013) and WFNS grade post-resuscitation (OR=3.43;<0.0001) were associated with poor outcome. Receiving operating characteristics/area under the curve (AUC) analysis demonstrated that WFNS determined post-resuscitation had a stronger association with poor outcome (AUC=0.90) than WFNS assessed upon admission or at nadir. Conclusions: Timing of WFNS assessment affects its prognostic value. Outcome after aSAH is best predicted by rating WFNS after neurological resuscitation.
Electrodiagnostic Characteristics Suggestive of Muscle-Specific Kinase Myasthenia Gravis
Objective: To analyze insulin delivery and glycemic metrics throughout the menstrual cycle for women with type 1 diabetes using closed loop control (CLC) insulin delivery. Methods: Menstruating women using a CLC system in a clinical trial were invited to record their menstrual cycles through a cycle-tracking application. Sixteen participants provided data for this secondary analysis over three or more complete cycles. Insulin delivery and continuous glucose monitoring (CGM) data were analyzed in relation to reported cycle phases. Results: Insulin delivery and CGM metrics remained consistent during cycle phases. Intraparticipant variability of CGM metrics and weight-based insulin delivery did not change through cycle phases. Conclusions: For this sample of menstruating women with type 1 diabetes using a CLC system, insulin delivery and glycemic metrics remained stable throughout menstrual cycle phases. Additional studies in this population are needed, particularly among women who report variable glycemic control during their cycles. Trial Registration: NCT03591354.
Perfecting hysterosalpingography: Limitations to the use of disposable balloon catheter and its solution
AbstractObjectiveTo revive the use of the Kahn Uterine Trigger Cannula to overcome limitations associated with technical difficulties during hysterosalpingography (HSG) using the disposable balloon HSG catheter.MethodA case series was conducted of 17 patients who encountered technically difficult or incomplete HSG study while using a disposable HSG balloon catheter, also leading to false‐positive findings. Nine patients underwent a repeat HSG using a Kahn Uterine Trigger Cannula (Group 1). Eight patients underwent diagnostic laparoscopy and tubal perfusion testing using a Kahn Uterine Trigger Cannula (Group 2). The findings for each group in comparison to their initial HSG results using the disposable balloon HSG catheter are described.ResultsAll patients were noted to have patent fallopian tubes using a Kahn Uterine Trigger Cannula on repeat HSG or tubal perfusion testing during laparoscopy.ConclusionProviders who perform HSG studies should be familiar with the value of a Kahn Uterine Trigger Cannula when the traditional use of disposable HSG balloon catheter fails due to technical difficulty or incomplete study. The use of the Kahn Uterine Trigger Cannula in such situations can prevent inaccurate assessment and unnecessary interventions.
DOP44 Long-term use of ozanimod in patients with moderately to severely active Ulcerative Colitis
Abstract Background Ozanimod was approved by the FDA to treat patients (pts) with moderately to severely active Ulcerative Colitis (UC) based on the results from the 52-week (wk) phase 3 True North (TN) study. We sought to evaluate long-term efficacy and safety of ozanimod. Methods We examined data from an interim analysis of pts in the TN parent study who entered the ongoing TN open-label extension (OLE). Pts entered the TN OLE from the phase 3 TN study if they were non-responders at the end of induction, lost response during maintenance, or completed maintenance treatment, or from the phase 2 Touchstone OLE if they remained at study closure and received once-daily oral ozanimod 0.92 mg (equivalent to ozanimod HCl 1 mg). Clinical remission, clinical response, endoscopic improvement, and corticosteroid (CS)-free remission were evaluated at Wks 46, 94, and 142 in the TN OLE for all pts who entered the OLE from the TN parent study, and in the subset of pts in clinical response at the OLE entry. The data were analysed in the intent-to-treat population using observed cases (OC), which used the number of pts remaining in the study at the corresponding time point, and non-responder imputation (NRI), which used the number of pts remaining in the study at the corresponding time point and those who withdrew before the time point but would have reached the time point if they had stayed. Treatment-emergent adverse events were evaluated from the pooled phase 2 and phase 3 UC studies. Results A total of 823 pts from TN entered the TN OLE; as of the cut-off date (Sept 30, 2020), 64% completed Wk 46, 34% completed Wk 94, and 14% completed Wk 142 of the OLE. The most common reason for discontinuation was lack of efficacy (21%). Baseline demographics were similar as in the TN study. A total of 261 pts were in clinical response at the time of OLE entry. OC analyses showed that the percentage of pts achieving clinical remission, clinical response, endoscopic improvement, and CS-free remission was maintained over time (Table). Efficacy in the responders was higher compared to the total population and was comparable within the endpoints at Wks 46 and 94. Using the more conservative NRI analysis, the proportion of pts achieving each endpoint was lower than in the OC; however, after 94 wks of OLE treatment, 34% of all pts and 55% of the responders still maintained clinical response. No new safety signals were seen with longer-term ozanimod use in the 1158 pts in the pooled population. Conclusion UC pts from the phase 3 TN study demonstrated maintenance of response with long-term ozanimod treatment. These data reflect approximately 2 years of additional ozanimod treatment, with no new safety signals identified.
DOP40 Impact of corticosteroid usage on efficacy and safety outcomes in patients receiving upadacitinib for Ulcerative Colitis
Abstract Background The oral, selective Janus kinase inhibitor upadacitinib (UPA) has demonstrated efficacy as induction and maintenance therapy in patients with moderately to severely active Ulcerative Colitis (UC) in a Phase 3 clinical programme comprising two identical induction trials (U-ACHIEVE Induction [NCT02819635] and U-ACCOMPLISH [NCT03653026]) and a maintenance study (U-ACHIEVE Maintenance). This analysis assessed the impact of baseline corticosteroid (CS) use on the efficacy and safety of UPA in patients in these trials. Methods Patients were randomised 2:1 to UPA 45 mg once daily (QD) or placebo (PBO) for 8 weeks. Patients who achieved a clinical response at Week 8 were re-randomised 1:1:1 to UPA 15 mg QD, UPA 30 mg QD or PBO for 52 weeks. Here, we report induction and maintenance endpoints and safety data stratified by baseline CS use. Results Baseline demographics and disease characteristics were generally well balanced across treatment groups, regardless of baseline CS use. Clinical remission rates among patients receiving UPA 45 mg induction therapy did not differ by baseline CS use (Figure 1A). In the induction period, rates of treatment-emergent adverse events of special interest (AESI), including serious and opportunistic infections, were increased in the UPA 45 mg plus baseline CS group compared with the PBO and UPA without baseline CS groups (Table 1). In the maintenance study, CS tapering was mandated. CS-free remission at Week 52 (defined as clinical remission, per Adapted Mayo Score, and CS free for ≥90 days immediately prior to Week 52) was significantly increased with UPA 30 and 15 mg compared with PBO (both p<0.001; Figure 1B). Among patients receiving UPA maintenance, rates of treatment-emergent AESIs in the baseline CS versus no baseline CS groups were 33% versus 39% and 27% versus 35% in the UPA 30 mg and UPA 15 mg groups, respectively. Malignancy, major adverse cardiovascular events, venous thromboembolic events, and serious and opportunistic infections were reported infrequently in patients receiving UPA (Table 1). Conclusion This post hoc analysis suggests that, in patients with moderately to severely active UC, UPA is superior to PBO in conferring CS-free remission. Baseline CS use was not associated with any apparent efficacy benefit and carried a potential increased safety risk. These results suggest that achieving early disease control with UPA and without CS use is an optimal treatment strategy for this population.

CD46 Receptor Utilization by Species D Human Adenovirus Serotype 26 (HAdV26)
The human species D Ad26 is being investigated as a low-seroprevalence vector for oncolytic virotherapy and gene-based vaccination against HIV-1 and SARS-CoV-2. However, there is debate in the literature about its tropism and receptor utilization, which directly influence its efficiency for certain applications. This work was aimed at determining which receptor(s) this virus uses for infection and its role in virus biology, vaccine efficacy, and, importantly, vaccine safety.
S854 Upadacitinib Is Effective at Inducing Clinical Remission and Response in Ulcerative Colitis Patients Regardless of Baseline Corticosteroid Use: Results From Two Phase 3 Studies
Abstract Myelofibrosis (MF) is a clonal stem cell neoplasm characterized by abnormal JAK-STAT signaling, chronic inflammation, cytopenias, and risk of transformation to acute leukemia. Despite improvements in the therapeutic options for patients with MF, allogeneic hematopoietic stem cell transplantation remains the only curative treatment. We previously demonstrated multiple immunosuppressive mechanisms in patients with MF, including increased expression of programmed cell death protein 1 (PD-1) on T cells compared with healthy controls. Therefore, we conducted a multicenter, open-label, phase 2, single-arm study of pembrolizumab in patients with Dynamic International Prognostic Scoring System category of intermediate-2 or greater primary, post-essential thrombocythemia or post-polycythemia vera myelofibrosis that were ineligible for or were previously treated with ruxolitinib. The study followed a Simon 2-stage design and enrolled a total of 10 patients, 5 of whom had JAK2V617mutation, 2 had CALR mutation, and 6 had additional mutations. Most patients were previously treated with ruxolitinib. Pembrolizumab treatment was well tolerated, but there were no objective clinical responses, so the study closed after the first stage was completed. However, immune profiling by flow cytometry, T-cell receptor sequencing, and plasma proteomics demonstrated changes in the immune milieu of patients, which suggested improved T-cell responses that can potentially favor antitumor immunity. The fact that these changes were not reflected in a clinical response strongly suggests that combination immunotherapeutic approaches rather than monotherapy may be necessary to reverse the multifactorial mechanisms of immune suppression in myeloproliferative neoplasms. This trial was registered at www.clinicaltrials.gov as #NCT03065400.
