ABSTRACT
Background: Rheumatologists have noted challenges in treating patients with systemic sclerosis (SSc) during the COVID-19 pandemic, such as patients on immunosuppressants and those with preexisting pulmonary issues.1 Also of potential concern was patients delaying treatment due to fears of COVID. Objectives: This study examined to what extent patients with SSc cancelled health-care appointments due to fears of COVID, how this correlated with their mental and physical functioning, and their levels of anxiety and depression. Methods: Participants were 60 people with SSc who had not had COVID-19 or been vaccinated for COVID. Participants had a mean age of 58 years (SD=11.5) and were primarily female (92%) and white (87%). Participants completed an online survey after learning about it from a sclero-derma organization newsletter or at their visit with a rheumatologist specializing in scleroderma in New York State, USA. Data were collected August 2020 through March 2021. Participants completed measures assessing health-related appointments attendance, Patient Reported Outcome Measurement Information System (PROMIS) measures (anxiety, depression, fatigue, sleep disturbance, pain intensity, physical function), coping strategies to deal with the pandemic, and reported functioning relevant to SSc (hand, gastrointestinal, dyspnea, and Raynaud's disease). Results: Due to COVID-19 concerns, 28 respondents (47%) cancelled one or more appointments with their primary care physician, specialist, physical or occupational therapist, pulmonologist, or dentist. Compared to those who did not cancel appointments due to COVID concerns, participants who cancelled reported higher anxiety, t(58) = 2.46, p =.02, higher sleep disturbance, t(56) = 3.31, p =.002, worse physical functioning, t(56) = 2.00, p =.05, more constipation, t(55) = 2.05, p =.045, and lower positive reframing as a coping strategy, t(56) = 2.08, p =.04. Many participants reported moderate or severe anxiety (36%), depression (22%), fatigue (32%), sleep disturbance (28%), and physical dysfunction (40%). As shown in Table 1, anxiety scores were positively correlated with scores on measures of fatigue, sleep disturbance, physical dysfunction, diarrhea, and the coping strategies of substance use, self-distraction, emotional support, behavioral disengagement, and venting. Depression scores were positively correlated with scores on measures of fatigue, sleep disturbance, physical dysfunction, pain intensity, dyspnea, diarrhea, and behavioral disengagement as a coping strategy. Conclusion: Almost half of participants cancelled one or more health appointments due to COVID fears. This subgroup reported significantly higher anxiety, sleep disturbance, constipation, worse physical functioning, and less coping with the pandemic by looking for the positive. Anxiety and/or depression also played a role in 42% of SSc patients and were related to a variety of worse mental and physical health correlates. Future research should examine the extent to which changes in health-related care during the pandemic have implications for disease progression in patients with SSc.
ABSTRACT
It is well established that COVID-19 carries a higher risk of morbidity and mortality in patients (pts) with hematologic malignancies. Emerging data suggests that despite the 3 COVID-19 vaccines with emergency use authorization (EUA) by the FDA inducing high levels of immunity in the general population, pts with hematologic malignancies have lower rates of seroconversion for the SARS-CoV-2 Spike antibody (Spike IgG) and thus possibly lower protection against severe COVID-19. We established a program of rapid vaccination and evaluation of response in an inner city minority population to help determine the factors that contribute to the poor seroconversion to COVID-19 vaccination in pts with hematologic malignancies. We conducted a cross-sectional cohort study of pts with hematologic malignancies seen at Montefiore Medical Center between March 29, 2021 and July 8, 2021 who completed their vaccination series with 1 of the 3 FDA EUA COVID-19 vaccines, Moderna, Pfizer, or Johnson & Johnson (J&J). We qualitatively measured Spike IgG production in all pts using the AdviseDx Spike IgG assay and performed quantitative analysis on pts who completed their vaccination series with at least 14 days (d) after the 2 nd dose of the Moderna or Pfizer vaccines or 28d after the single J&J vaccine. Safety data was collected via questionnaires or as part of the electronic medical record. We analyzed the characteristics of these pts using standard descriptive statistics and associations between pts characteristics, cancer subtypes, treatments, and vaccine response using a Fisher Exact test, Kruskal-Wallis Rank Sum test, or Kendall Tau-b test. A total of 121 pts with hematologic malignancies were enrolled and another 10 pts were included by retrospective chart review. Five pts did not have a Spike IgG performed after consent and excluded. Ten patients had Spike IgG testing before completion of their vaccination series and excluded from quantitative analyses. A total of 116 pts were included in immunogenicity analysis and 106 pts in quantitative analysis. Baseline characteristics and representative malignancies are listed in Table 1. Seventy pts (60%) received Pfizer, 36 pts (31%) Moderna, and 10 pts (9%) J&J. Median time from vaccination completion to Spike IgG was 40d. We observed a high-rate of seropositivity (86%) with 16 pts (14%) having a negative Spike IgG. Percent positivity was not statistically significant between vaccine types (p=0.50). We observed significantly lower seroconversion rates in pts with Non-Hodgkin lymphoma (p=0.005) and pts who received: cytotoxic chemotherapy (p=0.002), IVIG (p=0.01), CAR-T cell therapy (p=0.00002), and CD20 monoclonal antibodies (Ab) (p=0.0000008) especially within 6 mo of Spike Ab evaluation (p=0.01). All pts who received anti-CD19 (Axi-cel) CAR-T therapy (0/6) were seronegative, and 1 pt that received BCMA directed CAR-T (Cilta-cel) was seropositive with no association between timing CAR-T cell infusion and seroconversion/titer. Use of BCL2 inhibitors (p=0.04), CD20 monoclonal Ab (p=0.0009), CAR-T cell therapy (p=0.01), BTK inhibitors (p=0.04), current steroid use (p=0.002), and IVIG (p=0.003) also correlated with significantly lower Ab titers with a trend toward lower Ab titers in pts on any active cancer therapy at time of vaccination (p=0.051). Immunomodulatory drugs (p=0.01) and proteasome inhibitors (p=0.01) had significantly higher seroconversion rates, and pts with history prior COVID-19 (12/106) had significantly higher Ab titers (p=0.0003). Of 47 pts who received stem cell transplant, 43 received an autologous (37 seropositive, 6 seronegative) and 4 an allogeneic transplant (3 seropositive, 1 seronegative), with no significant association with seroconversion, Ab titer, or time since transplant (greater or less than 1 year). The majority of pts, 64% and 53%, reported no adverse effects (AE) to the 1 st and 2 nd dose respectively. The most common AE were mild in severity and included sore arm, muscle aches, fatigue, and fever. No life-threatening AE were observed. Our findings indicate hat vaccination is safe, effective, and well tolerated in the majority of pts with hematologic malignancies. We observed that pts receiving B-cell depleting therapies are unable to mount an effective serological response to COVID-19 vaccines and remain vulnerable to the disease. Novel immunization strategies (active or passive) are urgently needed in this population. [Formula presented] Disclosures: Gritsman: iOnctura: Research Funding.

ABSTRACT
Decitabine (Dec) and Azacitidine (Aza) that target DNA methyltransferase 1 (DNMT1) are hypomethylating agents (HMAs) approved to treat acute myeloid leukemia (AML) in combination with Venetoclax (Ven). The combination is also used to treat high-risk myelodysplastic syndromes, especially TP53-mutated (TP53mut) cases in which responses to HMA alone are short-lived. In most patients (pts), however, myelosuppression from treatment leads to frequent Ven duration and/or dose-reductions, and/or cycle delays. An approach to decrease HMA-mediated myelosuppression but maintain S-phase dependent DNMT1-targeting, evaluated in a previous clinical trial (https://doi.org/10.1111/bjh.16281), is to administer noncytotoxic doses/concentrations of Dec (0.2 mg/kg;~5 mg/m 2) by a frequent-distributed schedule of 1X/week. An approach to decrease Ven mediated myelosuppression but maintain cooperation with HMA, shown in pre-clinical studies, is to administer a single-dose prior to HMA. Ven can depolarize mitochondrial membranes;mitochondrial membrane-potential is essential to function of the mitochondrial enzyme DHODH that produces cytidine/deoxycytidine that competes with HMA in cells. Thus, Ven prior to HMA dosing temporarily inhibits de novo pyrimidine synthesis, to counter a major mechanism of resistance to HMA in MDS/AML, without suppressing normal myelopoiesis (https://doi.org/10.1182/blood-2020-143200). We conducted a retrospective analysis of all pts with TP53mut MDS or AML treated with weekly Ven and low-dose subcutaneous Dec at our institution. We analyzed the characteristics of these pts, response to therapy, and outcomes using standard descriptive statistics. Mutational testing was performed using a commercial next-generation sequencing (NGS) panel. Five pts, 3 male and 2 female, with TP53mut MDS or AML were treated with weekly Ven 400 mg on D1 and subcutaneous Dec 0.2 mg/kg on D2, administered weekly in 28 day cycles. Two pts had MDS (1 de novo, 1 treatment related) and 3 pts had AML (1 de novo, 2 secondary from prior MDS). Four pts (80%) received the treatment in frontline, all with poor performance status (PS), and 1 pt (20%) had R/R disease. Median age at diagnosis was 79 years [41-82]. The only young pt had prolonged severe cytopenias after 1 cycle Dec standard dosing during the peak of COVID-19 pandemic so was switched to this regimen. Of the 4 frontline treated pts, 2 pts had high-risk MDS, and 2 pts had adverse risk AML. The R/R pt had high-risk MDS transformed to AML that was refractory to 2 prior lines of therapy: standard Aza/Ven x5 cycles, then standard Vyxeos. Disease cytogenetics were complex in all pts. 60% (3/5) pts had sole TP53mut on NGS, with median variant allelic frequency (VAF) 48% [28-79]. 80% (4/5) pts were transfusion dependent prior to treatment. Median time to initiating therapy was 7 days from initial or refractory diagnosis [3-59] and median follow-up was 7.8 months (mo) [2.9-11.4]. The overall response rate (ORR) was 100%: 4/4 frontline pts had complete remissions (CR), and the 1 R/R pt achieved morphologic leukemia-free state (MLFS). Median time to best response was 2.9 mo. 50% (2/4) pts became transfusion independent. 40% (2/5) pts lost their TP53mut at best response, and another 40% (2/5) pts had significant reductions (83% and 38%) in TP53 mut VAF. The regimen was well tolerated with no pts stopping therapy due to adverse effects (AE). AE included G3/G4 neutropenia (80%), G1 thrombocytopenia (40%), nausea (20%), fatigue (20%), lower extremity edema (20%), pneumonia (60%), and neutropenic fever (20%) with a median of 1 unplanned hospitalization per pt during follow-up. 60% (3/5) pts remain in CR on continued therapy for a median of 7.8 mo [7.2-9.4] thus far. One pt underwent allogeneic stem cell transplantation, however, died 11.4 mo after conditioning due to transplant related mortality. The R/R pt died after being lost to follow-up 2.9 mo after therapy initiation. No pt had measurable relapse during follow-up. Combination weekly Ven with subcutaneous low-dose Dec is well tolerated yielding igh rates of clinical and molecular response in pts with TP53mut MDS/AML. Although small, this case-series extends previous clinical trial proof-of-activity of non-cytotoxic DNMT1-targeting to a high-risk, poor PS, historically chemorefractory patient population. The regimen allowed frequent, sustained exposure to therapy often not possible with standard HMA/Ven regimens.

ABSTRACT
Interleukin-6 (IL-6) is a pleiotropic cytokine with effects in immune regulation, inflammation, and infection. The use of drugs that inhibit IL-6 biological activity has been proposed as a treatment for patients with Coronavirus Disease 2019 (COVID-19). The rationale for this approach includes commitment to the concept that inflammation is a cause of lung damage in COVID-19 and belief that IL-6 is a pro-inflammatory molecule. Observational data thought to support IL-6 inhibition include elevated circulating IL-6 levels in COVID-19 patients and association between elevated IL-6 and poor clinical outcomes. However, IL-6 has significant anti-inflammatory properties, which calls into question the rationale for employing IL-6 blockade to suppress inflammation-induced tissue injury. Also, studies suggesting a beneficial role for IL-6 in the host response to infection challenge the strategy of using IL-6 blockade to treat COVID-19. In studies of recombinant IL-6 injected into human volunteers, IL-6 levels exceeding those measured in COVID-19 patients have been observed with no pulmonary adverse events or other organ damage. These observations question the role of IL-6 as a contributing factor in COVID-19. Clinical experience with IL-6 receptor antagonists such as tocilizumab demonstrates increase in severe and opportunistic infections, raising concern about using tocilizumab and similar agents to treat COVID-19. Trials of drugs to inhibit IL-6 activity in COVID-19 are ongoing and will shed light on the role of IL-6 in COVID-19 pathogenesis. However, until more information is available, providers should exercise caution in prescribing these therapies given the potential for patient harm.
