Hydroxychloroquine has been touted as a potential COVID-19 treatment. Tocilizumab, an inhibitor of IL-6, has also been proposed as a treatment of critically ill patients. In this retrospective observational cohort study drawn from electronic health records we sought to describe the association between mortality and hydroxychloroquine or tocilizumab therapy among hospitalized COVID-19 patients. Patients were hospitalized at a 13-hospital network spanning New Jersey USA between March 1, 2020 and April 22, 2020 with positive polymerase chain reaction results for SARS-CoV-2. Follow up was through May 5, 2020. Among 2512 hospitalized patients with COVID-19 there have been 547 deaths (22%), 1539 (61%) discharges and 426 (17%) remain hospitalized. 1914 (76%) received at least one dose of hydroxychloroquine and 1473 (59%) received hydroxychloroquine with azithromycin. After adjusting for imbalances via propensity modeling, compared to receiving neither drug, there were no significant differences in associated mortality for patients receiving any hydroxychloroquine during the hospitalization (HR, 0.99 [95% CI, 0.80-1.22]), hydroxychloroquine alone (HR, 1.02 [95% CI, 0.83-1.27]), or hydroxychloroquine with azithromycin (HR, 0.98 [95% CI, 0.75-1.28]). The 30-day unadjusted mortality for patients receiving hydroxychloroquine alone, azithromycin alone, the combination or neither drug was 25%, 20%, 18%, and 20%, respectively. Among 547 evaluable ICU patients, including 134 receiving tocilizumab in the ICU, an exploratory analysis found a trend towards an improved survival association with tocilizumab treatment (adjusted HR, 0.76 [95% CI, 0.57-1.00]), with 30 day unadjusted mortality with and without tocilizumab of 46% versus 56%. This observational cohort study suggests hydroxychloroquine, either alone or in combination with azithromycin, was not associated with a survival benefit among hospitalized COVID-19 patients. Tocilizumab demonstrated a trend association towards reduced mortality among ICU patients. Our findings are limited to hospitalized patients and must be interpreted with caution while awaiting results of randomized trials. Trial Registration: Clinicaltrials.gov Identifier: NCT04347993.

Patients with hematologic malignancies have poor outcomes from COVID infection and are less likely to mount an antibody response after COVID infection. This is a retrospective study of adult lymphoma patients who received the COVID vaccine between 12/1/2020 and 11/30/2021. The primary endpoint was a positive anti-COVID spike protein antibody level following the primary COVID vaccination series. The primary vaccination series was defined as 2 doses of the COVID mRNA vaccines or 1 dose of the COVID adenovirus vaccine. Subgroups were compared using Fisher’s exact test, and unadjusted and adjusted logistic regression models were used for univariate and multivariate analyses. A total of 243 patients were included in this study; 72 patients (30%) with indolent lymphomas; 56 patients (23%) with Burkitt’s, diffuse large B-cell lymphoma (DLBCL), and primary mediastinal B-cell lymphoma (PMBL) combined; 55 patients (22%) with chronic lymphocytic leukemia or small lymphocytic lymphoma (CLL/SLL); 44 patients (18%) with Hodgkin and T-cell lymphomas (HL/TCL) combined; 12 patients (5%) with mantle cell lymphoma; and 4 patients (2%) with other lymphoma types. One-hundred fifty-eight patients (65%) developed anti-COVID spike protein antibodies after completing the primary COVID vaccination series. Thirty-eight of 46 (83%) patients who received an additional primary shot and had resultant levels produced anti-COVID spike protein antibodies. When compared to other lymphoma types, patients with CLL/SLL had a numerically lower seroconversion rate of 51% following the primary vaccination series whereas patients with HL/TCL appeared to have a robust antibody response with a seropositivity rate of 77% (p = 0.04). Lymphoma patients are capable of mounting a humoral response to the COVID vaccines. Further studies are required to confirm our findings, including whether T-cell immunity would be of clinical relevance in this patient population.

The development of a prognostic mortality risk model for hospitalized COVID-19 patients may facilitate patient treatment planning, comparisons of therapeutic strategies, and public health preparations. We retrospectively reviewed the electronic health records of patients hospitalized within a 13-hospital New Jersey USA network between March 1, 2020 and April 22, 2020 with positive polymerase chain reaction results for SARS-CoV-2, with follow-up through May 29, 2020. With death or hospital discharge by day 40 as the primary endpoint, we used univariate followed by stepwise multivariate proportional hazard models to develop a risk score on one-half the data set, validated on the remainder, and converted the risk score into a patient-level predictive probability of 40-day mortality based on the combined dataset. The study population consisted of 3123 hospitalized COVID-19 patients; median age 63 years; 60% were men; 42% had >3 coexisting conditions. 713 (23%) patients died within 40 days of hospitalization for COVID-19. From 22 potential candidate factors 6 were found to be independent predictors of mortality and were included in the risk score model: age, respiratory rate [greater than or equal to]25/minute upon hospital presentation, oxygenation <94% on hospital presentation, and pre-hospital comorbidities of hypertension, coronary artery disease, or chronic renal disease. The risk score was highly prognostic of mortality in a training set and confirmatory set yielding in the combined dataset a hazard ratio of 1.80 (95% CI, 1.72, 1.87) for one unit increases. Using observed mortality within 20 equally sized bins of risk scores, a predictive model for an individual's 40-day risk of mortality was generated as -14.258 + 13.460*RS + 1.585*(RS-2.524)^2-0.403*(RS-2.524)^3. An online calculator of this 40-day COVID-19 mortality risk score is available at www.HackensackMeridianHealth.org/CovidRS. A risk score using six variables is able to prognosticate mortality within 40-days of hospitalization for COVID-19.

Background Hydroxychloroquine has not been associated with improved survival among hospitalized COVID-19 patients in the majority of observational studies and similarly was not identified as an effective prophylaxis following exposure in a prospective randomized trial. We aimed to explore the role of hydroxychloroquine therapy in mildly symptomatic patients diagnosed in the outpatient setting. Methods We examined the association between outpatient hydroxychloroquine exposure and the subsequent progression of disease among mildly symptomatic non-hospitalized patients with documented SARS-CoV-2 infection. The primary outcome assessed was requirement of hospitalization. Data was obtained from a retrospective review of electronic health records within a New Jersey USA multi-hospital network. We compared outcomes in patients who received hydroxychloroquine with those who did not applying a multivariable logistic model with propensity matching. Results Among 1274 outpatients with documented SARS-CoV-2 infection 7.6% were prescribed hydroxychloroquine. In a 1067 patient propensity matched cohort, 21.6% with outpatient exposure to hydroxychloroquine were hospitalized, and 31.4% without exposure were hospitalized. In the primary multivariable logistic regression analysis with propensity matching there was an association between exposure to hydroxychloroquine and a decreased rate of hospitalization from COVID-19 (OR 0.53; 95% CI, 0.29, 0.95). Sensitivity analyses revealed similar associations. QTc prolongation events occurred in 2% of patients prescribed hydroxychloroquine with no reported arrhythmia events among those with data available. Conclusions In this retrospective observational study of SARS-CoV-2 infected non-hospitalized patients hydroxychloroquine exposure was associated with a decreased rate of subsequent hospitalization. Additional exploration of hydroxychloroquine in this mildly symptomatic outpatient population is warranted.

Andre H. Goy, MD, is physician-in-chief of the Hackensack Meridian Health Oncology Care Transformation Service; and chairman, chief physician officer at the John Theurer Cancer Center of Hackensack University Medical Center in Hackensack, New Jersey; and program chair of the 27th Annual International Congress on Hematologic Malignancies®, hosted by Physicians' Education Resource®, LLC (PER®). The early data on these treatments show very high rates of CR in the frontline setting, which isn't surprising. [...]ibrutinib/venetoclax also resulted in high CR rates in the relapsed/refractory setting, even in patients with TP53 abnormalities. Many expectations [arose] surrounding BR with or without bortezomib, [but] that trial [NCT01415752] did not show a benefit.3 What it did show was that BR plus maintenance rituximab resulted in a median progression-free survival [PFS] of more than 6 years in this patient population. [...]younger patients who can tolerate dose-intensive therapies can receive a transplant, with induction and maintenance including a cytarabine-and-rituximab–based conditioning regimen.

Background: Diffuse large B-cell lymphoma (DLBCL) is the most common diagnosed aggressive B-cell lymphoma, with poor outcomes in those who experience relapsed or refractory (R/R) disease. Landmark clinical trials have demonstrated the efficacy and safety of anti-CD19 chimeric antigen receptor (CAR) T-cell therapy for patients with R/R DLBCL, though further exploration of real-world outcomes (RWOs) and safety data is warranted. Methods: A retrospective chart review was performed to collect patient and disease characteristics from patients with R/R DLBCL receiving CAR T-cell therapy for third-line treatment or beyond at the John Theurer Cancer Center as the standard of care. Results: We report on 82 patients with R/R DLBCL that successfully completed an infusion of an anti-CD19 CAR T-cell product at our institution. Best overall and complete response rates were 74.4% (95% CI, 64.9 to 83.8) and 67.1% (95% CI, 56.9 to 77.2), respectively. From the time of CAR T-cell infusion, median PFS was 26.5 months (95% CI, 8.6 months could not be estimated) and OS was not reached. Subgroup analyses revealed no statistical differences in outcomes by use of bridging therapy, Karnofsky performance status, transformed DLBCL status, and the type of CAR T-cell product used for this study. CAR T-cell therapy was well tolerated, with 58 patients (70.7%) experiencing cytokine-release syndrome and 17 patients (20.7%) experiencing immune effector cell-associated neurotoxicity syndrome. Conclusions: These results of RWOs in third-line patients with R/R DLBCL receiving anti-CD19 CAR T-cell therapy are comparable or superior to prior clinical trials and studies of RWOs, validating the strong efficacy and manageable toxicities of CAR T-cell therapy.

Idelalisib, which inhibits PI3K isoform delta, produced antitumor responses in nearly 60% of pretreated patients with indolent non-Hodgkin's lymphomas. Responses lasted a median of 11 months. Grade 3 or higher toxic effects were seen in 13 to 27% of patients. Indolent non-Hodgkin's lymphomas constitute approximately one third of all cases of non-Hodgkin's lymphoma and include follicular lymphoma, small lymphocytic lymphoma, marginal-zone lymphoma, and lymphoplasmacytic lymphoma with or without Waldenström's macroglobulinemia. 1 – 3 It was estimated that approximately 20,000 people in the United States were diagnosed with indolent non-Hodgkin's lymphoma in 2012 and that approximately 7000 died of this disease. 4 , 5 The mainstay of treatment for indolent non-Hodgkin's lymphoma is an anti-CD20 antibody (primarily rituximab) in combination with chemotherapy consisting of alkylating agents, anthracyclines, antimitotic agents, or purine analogues. Although the current treatments for indolent non-Hodgkin's lymphomas are initially effective in inducing . . .

ZUMA-1 safety management cohort 6 investigated the impact of prophylactic corticosteroids and earlier corticosteroids and/or tocilizumab on the incidence and severity of cytokine release syndrome (CRS) and neurologic events (NEs) following axicabtagene ciloleucel (axi-cel) in patients with relapsed/refractory large B-cell lymphoma (R/R LBCL). Prior analyses of cohort 6 with limited follow-up demonstrated no Grade ≥3 CRS, a low rate of NEs, and high response rates, without negatively impacting axi-cel pharmacokinetics. Herein, long-term outcomes of cohort 6 (N = 40) are reported (median follow-up, 26.9 months). Since the 1-year analysis (Oluwole, et al.Blood. 2022;138[suppl 1]:2832), no new CRS was reported. Two new NEs occurred in two patients (Grade 2 dementia unrelated to axi-cel; Grade 5 axi-cel–related leukoencephalopathy). Six new infections and eight deaths (five progressive disease; one leukoencephalopathy; two COVID-19) occurred. Objective and complete response rates remained at 95% and 80%, respectively. Median duration of response and progression-free survival were reached at 25.9 and 26.8 months, respectively. Median overall survival has not yet been reached. Eighteen patients (45%) remained in ongoing response at data cutoff. With ≥2 years of follow-up, prophylactic corticosteroids and earlier corticosteroids and/or tocilizumab continued to demonstrate CRS improvement without compromising efficacy outcomes, which remained high and durable.

Advancements in mantle cell lymphoma (MCL) have illuminated the disease’s molecular diversity, leading to a wide variation in the outcomes observed in MCL. Current prognostic risk scores are continuously revised to incorporate new updates in the mechanistic or biologic understanding of MCL. Nevertheless, key high-risk features of MCL associated with rapid disease progression and poor survival, such as TP53 mutations, complex karyotypes, and blastoid or pleomorphic morphologies, remain absent from available prognostic tools. The greater accessibility of genomic technologies, such as next-generation sequencing (NGS), has enabled clinicians to identify specific genetic alterations that serve as prognostic signals and disease monitoring parameters, cultivating accurate risk profiling that is illustrative of MCL heterogeneity. Through an increased understanding of distinct MCL behaviors, novel therapies that mechanistically target disease biology, including Bruton’s tyrosine kinase inhibitors, BCL-2 inhibitors, ROR1 inhibitors, and bispecific T-cell engagers, have broadened the treatment armamentarium for relapsed/refractory MCL cases. These interventions, in addition to chemoimmunotherapy and autologous stem cell transplantation mainstays, confer the individualization of treatment and improved survival outcomes. Further exploration of the considerable biological heterogeneity of MCL can enhance knowledge, management, and the treatment of this rare lymphoma subtype.
