Neutralizing COVID-19 Convalescent Plasma in Adults Hospitalized With COVID-19: A Blinded, Randomized, Placebo-Controlled Trial.

BACKGROUND: Convalescent plasma has been one of the most common treatments for COVID-19, but most clinical trial data to date have not supported its efficacy. RESEARCH QUESTION: Is rigorously selected COVID-19 convalescent plasma with neutralizing anti-SARS-CoV-2 antibodies an efficacious treatment for adults hospitalized with COVID-19? STUDY DESIGN AND METHODS: This was a multicenter, blinded, placebo-controlled randomized clinical trial among adults hospitalized with SARS-CoV-2 infection and acute respiratory symptoms for < 14 days. Enrolled patients were randomly assigned to receive one unit of COVID-19 convalescent plasma (n = 487) or placebo (n = 473). The primary outcome was clinical status (disease severity) 14 days following study infusion measured with a seven-category ordinal scale ranging from discharged from the hospital with resumption of normal activities (lowest score) to death (highest score). The primary outcome was analyzed with a multivariable ordinal regression model, with an adjusted odds ratio (aOR) < 1.0 indicating more favorable outcomes with convalescent plasma than with placebo. In secondary analyses, trial participants were stratified according to the presence of endogenous anti-SARS-CoV-2 antibodies ("serostatus") at randomization. The trial included 13 secondary efficacy outcomes, including 28-day mortality. RESULTS: Among 974 randomized patients, 960 were included in the primary analysis. Clinical status on the ordinal outcome scale at 14 days did not differ between the convalescent plasma and placebo groups in the overall population (aOR, 1.04; one-seventh support interval [1/7 SI], 0.82-1.33), in patients without endogenous antibodies (aOR, 1.15; 1/7 SI, 0.74-1.80), or in patients with endogenous antibodies (aOR, 0.96; 1/7 SI, 0.72-1.30). None of the 13 secondary efficacy outcomes were different between groups. At 28 days, 89 of 482 (18.5%) patients in the convalescent plasma group and 80 of 465 (17.2%) patients in the placebo group had died (aOR, 1.04; 1/7 SI, 0.69-1.58). INTERPRETATION: Among adults hospitalized with COVID-19, including those seronegative for anti-SARS-CoV-2 antibodies, treatment with convalescent plasma did not improve clinical outcomes.

Efficacy and Safety of Bevacizumab Plus Erlotinib in Patients with Renal Medullary Carcinoma.

PURPOSE: To assess the efficacy and safety of bevacizumab plus erlotinib in patients with RMC. METHODS: We retrospectively reviewed the records of patients with RMC treated with bevacizumab plus erlotinib at our institution. RESULTS: Ten patients were included in the study. Two patients achieved a partial response (20%) and seven patients achieved stable disease (70%). Tumor burden was reduced in seven patients (70%) in total, and in three out of five patients (60%) that had received three or more prior therapies. The median progression-free survival (PFS) was 3.5 months (95% CI, 1.8-5.2). The median overall survival (OS) from bevacizumab plus erlotinib initiation was 7.3 months (95% CI, 0.73-13.8) and the median OS from diagnosis was 20.8 months (95% CI, 14.7-26.8). Bevacizumab plus erlotinib was well tolerated with no grade ≥4 adverse events and one grade 3 skin rash. Dose reduction was required in one patient (10%). CONCLUSIONS: Bevacizumab plus erlotinib is clinically active and well tolerated in heavily pre-treated patients with RMC and should be considered a viable salvage strategy for this lethal disease.

Passive Immunity Trial for Our Nation (PassITON): study protocol for a randomized placebo-control clinical trial evaluating COVID-19 convalescent plasma in hospitalized adults.

BACKGROUND: Convalescent plasma is being used widely as a treatment for coronavirus disease 2019 (COVID-19). However, the clinical efficacy of COVID-19 convalescent plasma is unclear. METHODS: The Passive Immunity Trial for Our Nation (PassITON) is a multicenter, placebo-controlled, blinded, randomized clinical trial being conducted in the USA to provide high-quality evidence on the efficacy of COVID-19 convalescent plasma as a treatment for adults hospitalized with symptomatic disease. Adults hospitalized with COVID-19 with respiratory symptoms for less than 14 days are eligible. Enrolled patients are randomized in a 1:1 ratio to 1 unit (200-399 mL) of COVID-19 convalescent plasma that has demonstrated neutralizing function using a SARS-CoV-2 chimeric virus neutralization assay. Study treatments are administered in a blinded fashion and patients are followed for 28 days. The primary outcome is clinical status 14 days after study treatment as measured on a 7-category ordinal scale assessing mortality, respiratory support, and return to normal activities of daily living. Key secondary outcomes include mortality and oxygen-free days. The trial is projected to enroll 1000 patients and is designed to detect an odds ratio ≤ 0.73 for the primary outcome. DISCUSSION: This trial will provide the most robust data available to date on the efficacy of COVID-19 convalescent plasma for the treatment of adults hospitalized with acute moderate to severe COVID-19. These data will be useful to guide the treatment of COVID-19 patients in the current pandemic and for informing decisions about whether developing a standardized infrastructure for collecting and disseminating convalescent plasma to prepare for future viral pandemics is indicated.

Novel Translocation in Acute Myeloid Leukemia: Case Report and Review of Risk-Stratification and Induction Chemotherapy in Patients With Acute Myeloid Leukemia.

Identification of chromosomal abnormalities in patients with acute myeloid leukemia (AML) has contributed substantially to our current understanding of the molecular pathogenesis underlying leukemogenesis, and risk-stratification based on molecular abnormalities both influences treatment strategies and aids in determining prognosis. While over 300 established mutations have been documented in AML, the enhanced availability of genetic analysis and the increase in awareness of uncommon chromosomal translocations have made it possible for rare, apparently unique translocations to become recognized and to ultimately gain prognostic significance. Hence, we present a case of AML with a novel, balanced 2;12 translocation involving breakpoints previously undescribed. Although the patient required second induction, first remission was ultimately achieved. While the prognostic significance of this translocation is not fully elucidated, it is our hope that documentation of this patient's presentation will help to characterize the significance of a yet undefined cytogenetic abnormality in AML.

Zoledronic acid for prevention of bone loss in patients receiving primary therapy for lymphomas: a prospective, randomized controlled phase III trial.

UNLABELLED: In patients with newly diagnosed lymphoma, low bone mineral density (BMD) is common at diagnosis and worsens with therapy. Our randomized phase III trial demonstrates that 2 doses of zoledronic acid (ZA) and supplementation with calcium and vitamin D effectively prevent further bone loss. BACKGROUND: Patients with lymphoma are at risk of development of bone mineral density (BMD) loss from therapy with high-dose corticosteroids and alkylating agents. Zoledronic acid (ZA), a bisphosphonate, may prevent this complication of therapy. We evaluated the effect of ZA on the change in BMD and surrogate biomarkers in patients with lymphoma receiving initial chemotherapy. PATIENTS AND METHODS: Our phase III trial randomized 74 patients with newly diagnosed lymphoma and a baseline BMD of ≥ -2.0 to receive oral calcium and vitamin D daily with or without ZA at enrollment and at 6 months after enrollment. BMD was evaluated at baseline and 1 year after enrollment. Secondary biomarker endpoints were collected at baseline and at 3, 6, 9, and 12 months after enrollment. RESULTS: Forty-three percent of patients had baseline osteopenia. Fifty-three patients were evaluable for response: 24 received ZA and had stable BMD during the observation period, whereas 29 patients in the control group had decreased BMD (P < .05 at lumbar spine and bilateral femoral neck). Twenty-one randomized patients were not evaluable for response because of lymphoma progression or death, withdrawn consent/incomplete testing, or ineligibility. Bone biomarkers were higher in the control group at all intervals after treatment (P < .001). No fractures or intervention-related toxicities were observed during this trial. CONCLUSIONS: Newly diagnosed patients with lymphoma are at risk of low BMD, which may worsen with therapy. Treatment with ZA effectively stabilizes BMD and prevents bone loss. Our data suggest that BMD testing and prophylaxis should be considered as an early intervention for a preventable problem.

Azacitidine for the treatment of myelodysplastic syndrome.

The myelodysplastic syndromes (MDS) encompass a heterogeneous group of malignant hematologic disorders characterized by ineffective hematopoiesis, peripheral cytopenias, frequent karyotypic abnormalities and significant risk for transformation to acute myeloid leukemia (AML). The prognosis of patients with intermediate- or high-risk MDS is very poor. This is due to the fact that standard therapeutic options are largely palliative. Neither autologous stem cell transplantation (SCT) nor chemotherapeutic regimens have been shown to prolong survival in patients with MDS. Allogeneic SCT, while potentially curative, is only available to a selected group of patients and is associated with high morbidity and mortality in elderly patients, which constitute the majority of patients with MDS. Hypermethylation of tumor-suppressor genes has been invoked as an important pathogenetic mechanism in MDS. The pyrimidine nucleoside analog azacitidine, which inhibits DNA methyltransferases, has recently become the first therapeutic to prolong survival in patients with MDS, thus changing the natural history of these malignancies. The activity of azacitidine in MDS has spurred the development of combinations of this agent with other epigenetic modifiers for the treatment of MDS and AML.
