Abstract Patients treated with allogeneic hematopoietic cell transplantation (HCT) are at risk of cytomegalovirus (CMV) reactivation and disease, which results in increased morbidity and mortality. Although universal antiviral prophylaxis against CMV improves outcomes in solid organ transplant recipients, data have been conflicting regarding such prophylaxis in patients undergoing allogeneic HCT. We conducted a systematic review of randomized trials of prophylactic antivirals against CMV after allogeneic HCT to summarize the evolution of the field over the last 35 years and evaluate the prophylactic potential of antiviral agents against CMV after allogeneic HCT. Electronic databases were queried from database inception through 31 December 2017. For included studies, incidence of CMV infection and all-cause mortality were collected as primary outcomes; CMV disease incidence, use of preemptive therapy, and drug toxicities were collected as secondary outcomes. Nineteen clinical trials conducted between 1981 and 2017 involving a total of 4173 patients were included for review. Prophylactic strategies included use of acyclovir, valacyclovir, ganciclovir, maribavir, brincidofovir, and letermovir compared with placebo or a comparator antiviral. Fourteen trials that compared antiviral prophylaxis with placebo demonstrated overall effectiveness in reducing incidence of CMV infection (odds ratio [OR], 0.49; 95% confidence interval [CI], 0.42-0.58), CMV disease (OR, 0.56; 95% CI, 0.40-0.80), and use of preemptive therapy (OR, 0.51; 95% CI, 0.42-0.62; 6 trials); however, none demonstrated reduction in all-cause mortality (OR, 0.96; 95% CI, 0.78-1.18) except the phase 3 trial of letermovir (week-24 OR, 0.59; 95% CI, 0.38-0.98). Additional research is warranted to determine patient groups most likely to benefit from antiviral prophylaxis and its optimal deployment after allogeneic HCT.

Introduction Cytomegalovirus (CMV) is one of the most common and clinically significant viral infections following allogeneic hematopoietic cell transplantation (HCT). Currently available options for CMV prophylaxis and treatment present challenges related to side effects and cost. Methods In this retrospective medical record review, the incidence of clinically significant CMV infection (CMV disease or reactivation requiring preemptive treatment) following allogeneic HCT was compared in patients receiving valacyclovir 1 g three times daily versus acyclovir 400 mg every 12 h for viral prophylaxis. Results Forty-five patients who received valacyclovir were matched based on propensity scoring to 35 patients who received acyclovir. All patients received reduced-intensity conditioning regimens containing anti-thymocyte globulin. Clinically significant CMV infection by day + 180 was lower in the valacyclovir group compared to the acyclovir group (18% vs. 57%, p = 0.0004). Patients receiving valacyclovir prophylaxis also had less severe infection evidenced by a reduction in CMV disease, lower peak CMV titers, delayed CMV reactivation, and less secondary neutropenia. Conclusion Prospective evaluation of valacyclovir 1 g three times daily for viral prophylaxis following allogeneic HCT is warranted. Due to valacyclovir's favorable toxicity profile and affordable cost, it has the potential to benefit patients on a broad scale as an option for CMV prophylaxis.

AbstractCytomegalovirus (CMV), the beta-human herpesvirus type 5 (HHV-5), is a major cause of morbidity in immunocompromised hosts, especially recipients of allogeneic hematopoietic cell transplantation (HCT) or solid organ transplantation. The standard-of-care approach to CMV prevention based on CMV surveillance-guided preemptive therapy is being challenged by the recent approval of letermovir (LMV) for primary prophylaxis. Real-word clinical data show dramatic improvement in the reduction of risk of CMV infection and any CMV viremia in all studies performed so far. LMV is the drug that is breaking the paradigm of preemptive therapy with shift to prophylaxis. A summary of reported data presented in 2019 annual meetings of American Society of Transplantation and Cellular Therapy (ASTCT), European Society for Blood and Marrow Transplantation (EBMT) and American Society of Hematology (ASH), as well as already published results, is presented in this review. A total number of 401 adult high-risk patients on primary prophylaxis after HCT were reported in 11 studies up to January 1, 2020. It was shown that fewer patients in the LMV arms had any CMV reactivation or need for CMV treatment compared with the any other prophylactic or preemptive approaches. In conclusion, LMV is much highly effective than CMV-guided preemptive therapy in preventing CMV infection and CMV disease. The use of LMV in prophylaxis results in an improvement in overall survival during the first 24 and 48 weeks. LMV has a favorable safety profile, as it does not cause myelotoxicity. Current guidelines of European Conference on Infections in Leukemia (ECIL7) recommend LMV for the use in prophylaxis of CMV infection in patients after allogeneic hematopoietic cell transplant.

Abstract Background: CMV disease is a major complication of allogeneic hematopoietic cell transplantation (HCT). Our widely used diagnostic modalities (H&E-based morphology and CMV IHC) are suboptimal in accuracy and frequently equivocal. Furthermore, current therapies for CMV disease are toxic and can cause serious complications such as prolonged neutropenia or progressive renal insufficiency. As a result, more accurate diagnosis that would help avoid potentially toxic treatments in patients who are truly negative for disease is highly desirable. The purpose of this study was to evaluate whether CMV PCR performed on formalin-fixed paraffin-embedded (FFPE) tissue offers additional diagnostic value to H&E/IHC in allogeneic HCT recipients. Methods: Following the approval by our institutional review board, the electronic medical records of all adult patients who underwent an allogeneic HCT at Washington University School of Medicine (St. Louis, MO) between 2010 and 2015 and had a post-transplant upper/lower endoscopy were retrospectively reviewed. An additional inclusion criterion was the availability of CMV DNA PCR on the blood within 7 days of biopsy.FFPE specimens were reviewed by a pathologist who was blinded to clinical and molecular results. The specimens were reviewed for H&E-based morphology and IHC findings. Tissue PCR was performed by a laboratory technician who was blinded to clinical, H&E, and IHC findings. Results: A total of 151 samples were included. Concurrent CMV viremia was present in 38% of cases. According to H&E/IHC results, cases were classified as double-positive (n = 17), double-negative (n = 105), or equivocal (n = 29) (Table 1). In receiver operating characteristic curve analysis for classification of H&E/IHC-concordant cases using tissue PCR, the optimal cycle threshold (Ct) value was 40 (area under the curve = 0.91, P < 0.001, sensitivity 94%, specificity 79%, positive predictive value 42%, and negative predictive value 99%; Figure 1). Using this cutoff, 45% of equivocal cases were classified as negative, suggesting that anti-CMV treatment in almost half of H&E/IHC-equivocal cases is unnecessary and potentially detrimental. Among viremic, H&E/IHC-concordant cases, tissue PCR with a cutoff Ct of 40 had a sensitivity of 100%, specificity of 50%, PPV of 44%, and NPV of 100%. Among non-viremic, H&E/IHC-concordant cases, these numbers were 80%, 91%, 36%, and 99%, respectively. In this analysis on viremic cases, all double-positive and 50% of double-negative cases were classified positive, while 31% of equivocal cases were classified negative. In non-viremic patients, 91% of double-negatives, 20% of double-positives, and 62% of equivocal cases were classified negative. Conclusions: Tissue PCR is a useful adjunct to H&E and IHC, particularly in H&E/IHC-equivocal cases, and can help avoid unnecessary, potentially toxic, anti-CMV treatment in cases without tissue-invasive disease. We propose the following algorithm: (i) If the cost and labor associated with tissue PCR on all patients are prohibitive, start with H&E and IHC. Perform tissue PCR in H&E/IHC-equivocal cases and consider this test also in non-viremic, H&E/IHC-positive cases. In all other cases forgo tissue PCR. (ii) If the cost and labor are not prohibitive, perform PCR on all cases. A negative PCR rules out CMV disease. In PCR-positive cases, use H&E/IHC results and treat only if H&E and IHC are both positive. One limitation of our study is related to using FFPE specimens rather than the real-life fresh tissue. Our results warrant testing in prospective studies. Disclosures DiPersio: Incyte Corporation: Research Funding.

Abstract BACKGROUND: Despite recent advances, mortality rates after allogeneic hematopoietic cell transplantation remain high and cannot accurately predicted. PURPOSE: To determine the value of pretransplant factors in predicting all-cause mortality during first 1 year after allogeneic HCT. PATIENTS AND METHODS: A retrospective review of 303 consecutive allogeneic hematopoietic cell transplants was performed with attention to mortality and pretransplant factors in three hematopoietic cell transplantation centers between 2000 and 2005 in Japan. Patients underwent transplantation from sibling (n=200) or unrelated donors (n=104) with myeloablative (n=188) or nonmyeloablative conditioning (n=116). Pretransplant factors and the hematopoietic cell transplantation-specific comorbidity index (HCT-CI: Sorror et. al.) were assessed with general linear model (GML) analysis. RESULTS: Mortality before 1 year occurred in 145 of 303(48.3%) transplant recipients. The number of prior chemotherapy regimens and the HCT-CI were found to be useful predictors of early mortality. Kaplan-Meier estimates of survival as stratified by the HCT-CI (Fig.1) and the number of prior chemotherapy (Fig.2). The HCT-CI were useful for predicting outcomes. However, the sample size of patients with scores of 1 or more, captured by the HCT-CI did not exceed 15%. Futher, the number of prior chemotherapy regimens showed better suvival prediction. CONCLUSION: The number of prior chemotherapy regimens will be a promising tool to identify patient at risk for all-cause mortality during first 1 year after allogeneic HCT. Figure Figure

Abstract Reduced-intensity allogeneic hematopoietic cell transplantation (HCT) is increasingly considered as a therapeutic option for young patients with advanced chronic lymphocytic leukemia (CLL). We report 59 consecutive CLL patients who underwent allogeneic HCT following fludarabine and melphalan conditioning at four different institutions. For graft-versus-host disease (GVHD) prophylaxis, 38 patients (Cohort 1) received alemtuzumab (20–100 mg) and cyclosporine; and 21 patients (Cohort 2) received cyclosporine plus methotrexate or mycophenolate. Donors were 47 HLA-matched siblings and 12 unrelated volunteers, 6 of whom were mismatched. Median age at transplant was 53 (range, 34–64) years and median number of previous chemotherapy regimens was 3 (1–6), with 39% of patients being refractory to fludarabine. Nine patients had previously failed an autologous HCT. Fluorescent in-situ hybridization and IgVH mutation status data were available in 33 (56%) and 31 (53%) patients, respectively, being unfavorable (17p- or 11q-) in 22 (67%) and unmutated in 24 (77%) of them. All but 1 patient engrafted, and the median interval to neutrophil recovery (> 0.5 × 109/l) was 14 (range, 10–36) days. Twenty patients (34%), mostly from Cohort 1, received escalated donor lymphocyte infusions due to mixed chimerism or disease relapse. The overall complete response rate among 53 patients with measurable disease at the time of transplantation was 70%, whereas 21% had stable disease. Grade II-IV acute GVHD was observed in 14 (37%) and 12 (57%) patients from Cohorts 1 and 2, respectively (P = 0.17). Extensive chronic GVHD was observed in 3 (8%) and 10 (48%) patients from Cohorts 1 and 2, respectively (P < 0.01). The incidence of cytomegalovirus reactivation was not significantly different between cohorts (67% vs 47%, P = 0.23). With a median follow-up of 36 (range, 3–99) months for survivors, 18 (30%) patients have died, 3 of progressive disease and 15 of transplant-related complications. The 3-year overall survival (OS), progression-free survival (PFS) and non-relapse mortality were 66% (95% CI 48–84%), 38% (20–56%) and 21% (8–34%), respectively, for Cohort 1 and 65% (44–86%), 54% (32–76%) and 29% (10–48%) for Cohort 2 (P = 0.66; P = 0.33; and P = 0.53). Despite low patient numbers, alemtuzumab seemed particularly effective for unrelated donor recipients, with a 3-year OS and PFS of 54% and 40% for Cohort 1; and 33% and 0% for Cohort 2 (P = 0.02 and P = 0.07). In conclusion, results with reduced-intensity allogeneic HCT are promising for these poor-prognosis patients. Furthermore, the alemtuzumab-based regimen was effective in reducing the chronic GVHD rate with no negative effect on NRM, PFS or OS.

Abstract Abstract 2260 Poster Board II-237 Several studies have demonstrated that genetic variation in cytokine genes can modulate the immune reactions after allogeneic hematopoietic cell transplantation (HCT). High mobility group box 1 protein (HMBG1) is a pleiotropic cytokine that functions as a proinflammatory signal, important for the activation of antigen presenting cells (APC) and propagation of inflammation. HMGB1 is implicated in the pathophysiology of a variety of inflammatory diseases, and we have recently found the variation in the HMGB1gene to be associated with mortality in patients with systemic inflammatory response syndrome (SIRS). To assess the impact of the genetic variation in HMGB1 on outcome after allogeneic HCT, we genotyped 276 and 146 patient/donor pairs treated with allogeneic HCT for hematologic malignancies following myeloablative or non-myeloablative conditioning. Associations between genotypes and outcome were only observed in the cohort treated with myeloablative conditioning. Patient homozygosity or heterozygosity for the –1377delA minor allele was associated with increased risk of relapse (hazard ratio (HR) 2.11, P=0.02) and increased relapse related mortality (RRM) (P=0.03). The –1377delA minor allele has previously been associated with mortality in patients with SIRS, and although SIRS and allogeneic HCT are different entities the confirmative association of this polymorphic locus with mortality in 2 independent studies suggests that it is of pathophysiological importance. The three polymorphisms, 3814C>G, 1177G>C and 2351insT, tended to have the same effect on transplantation outcome, due to a moderate to strong linkage disequilibrium between loci. Of these three polymorphisms, patient homozygosity for the 3814C>G minor allele showed the strongest association with increased overall survival (HR 0.13, P=0.04), progression free survival (HR 0.30, P=0.05) and decreased probability of RRM (P=0.03). Patient carriage of the 2351insT minor allele reduced the risk of grade 2 to 4 acute graft versus host disease (GVHD) (HR 0.60, P=0.01), while donor carriage of the minor allele displayed a gene dosage effect, with a successive increase in risk of developing limited or extensive chronic GVHD per minor allele carried (HR 1.54, P=0.01). That patient HMGB1 genotypes were associated with outcomes dependent on primarily patient APCs, and that donor genotypes were associated with a, in part, donor APC dependent outcome, could suggest that the polymorphisms in HMGB1 influence the transcription of HMGB1 in APCs induced by the proinflammatory milieu after myeloablative conditioning, rather than the passively released from damaged cells, although these two mechanisms are not mutually exclusive. Our findings suggest that the inherited variation in HMGB1 is associated with outcome after allogeneic HCT following myeloablative conditioning. None of the polymorphisms were associated with treatment related mortality. Disclosures: No relevant conflicts of interest to declare.
