The TCI Clinical Encounter Program for PhD Students in Cancer Biology: a Feasibility Pilot.

Clinical rotations are often not included in graduate-level cancer biology curricula; however, basic insight into clinical oncology is often crucial for developing translational research that addresses unmet needs with the potential to benefit cancer patients. We describe a needs assessment, design, implementation, and descriptive evaluation of an oncology-specific pilot clinical encounter program developed for PhD students in the Cancer Biology Training Area (CAB) in the Graduate School of Biomedical Sciences (GSBS) and Tisch Cancer Institute (TCI) at the Icahn School of Medicine at Mount Sinai (ISMMS). Prior to the development of this pilot program, CAB students, in years 2-5 + , were surveyed to determine their interest in a structured clinical experience. Seventeen out of thirty-one students responded (55%) to the survey. Of those seventeen respondents, fifteen (88.2%) expressed that exposure to cancer patients in the clinical setting would be useful for their pre-doctoral biomedical science and cancer biology training and indicated an interest in participating in the clinical encounter program. Based on these responses, a three-session clinical encounter pilot program was designed. Two separate cohorts of 5 students participated in this pilot program. During a formal debrief, following the clinical experience, students commented on the resilience of patients and the importance of research on clinical decision making, and reported that they found the experience motivational. Five out of 10 students responded (50%) to a post-program assessment survey; all five respondents answered that they would recommend the clinical encounter program to their peers. While limited in size and scope, this pilot TCI Clinical Encounter Program proved feasible and has the potential to enrich and inform the experience of PhD students pursing advanced degrees in a cancer biology.

Tisch Cancer Institute Scholars Program: Mentored Cancer Research Training Pipeline for Medical Students.

Cancer research has led to unprecedented advances in treatment in recent decades. Physician-scientists have played a crucial role in these advances given their unique perspective at the intersection between basic research and clinical care, though their representation in cancer research has been in progressive decline. Cancer research programs that feature strong mentorship at the medical student level are associated with increased likelihood of alumni choosing a cancer research career path. In an effort to increase the cancer research medical student training pipeline, senior research faculty from the Tisch Cancer Institute (TCI) at the Icahn School of Medicine at Mount Sinai (ISMMS) developed the TCI Scholars Program, a rigorous mentored research training program funding medical students' summer research. This program is currently in its third year and has garnered significant interest among mentors and students alike from all four TCI Cancer Center Support Grant (CCSG)-funded research programs. Herein, we describe the development, implementation, evaluation, and major outcomes of this program.

Phase 2 study of romiplostim in patients with low- or intermediate-risk myelodysplastic syndrome receiving azacitidine therapy.

We evaluated the efficacy and safety of romiplostim, a thrombopoietin mimetic, in patients with low- or intermediate-risk myelodysplastic syndromes (MDS) receiving azacitidine therapy. Forty patients with low- or intermediate-risk MDS were stratified by baseline platelet counts (< 50 vs ≥ 50 × 10(9)/L) and randomized to romiplostim 500 µg or 750 µg or placebo subcutaneously once weekly during 4 cycles of azacitidine. The primary endpoint was the incidence of clinically significant thrombocytopenic events, defined by grade 3 or 4 thrombocytopenia starting on day 15 of the first cycle or platelet transfusion at any time during the 4-cycle treatment period. No formal hypothesis testing was planned. The incidence of clinically significant thrombocytopenic events in patients receiving romiplostim 500 µg, romiplostim 750 µg, or placebo was 62%, 71%, and 85%, respectively. The incidence of platelet transfusions was 46%, 36%, and 69%, respectively. These differences were not statistically significant with the small numbers in each group. Romiplostim 750 µg significantly raised median platelet counts during cycle 3 on day 1 (P = .0373) and at the nadir (P = .0035) compared with placebo. Grade 3 rash and arthralgia each were reported in 1 romiplostim-treated patient (4%). This study suggests romiplostim may provide clinical benefits in MDS patients during azacitidine therapy.

Tales from New York City, the pandemic epicenter: A case study of COVID-19 impact on clinical and translational research training at the Icahn School of Medicine at Mount Sinai.

In the spring of 2020, New York City was at the epicenter of the COVID-19 pandemic in the USA, resulting in disruption of TL1 and KL2-mentored Clinical and Translational Science (CTS) research at the Icahn School of Medicine at Mount Sinai (ISMMS). The impact of the pandemic on trainees' research productivity and career plans was explored using a qualitative survey. Participant responses were analyzed using coding and categorization. Six key themes emerged: redirection of effort, reduced access to people, lack of access to resources, home as a workplace, future uncertainty, and stress and anxiety. Insight into participant experiences allows for the development of support strategies and resources to address trainee needs.

Biomarkers and outcomes of COVID-19 hospitalisations: systematic review and meta-analysis.

OBJECTIVE: To evaluate association between biomarkers and outcomes in COVID-19 hospitalised patients. COVID-19 pandemic has been a challenge. Biomarkers have always played an important role in clinical decision making in various infectious diseases. It is crucial to assess the role of biomarkers in evaluating severity of disease and appropriate allocation of resources. DESIGN AND SETTING: Systematic review and meta-analysis. English full text observational studies describing the laboratory findings and outcomes of COVID-19 hospitalised patients were identified searching PubMed, Web of Science, Scopus, medRxiv using Medical Subject Headings (MeSH) terms COVID-19 OR coronavirus OR SARS-CoV-2 OR 2019-nCoV from 1 December 2019 to 15 August 2020 following Meta-analyses Of Observational Studies in Epidemiology (MOOSE) guidelines. PARTICIPANTS: Studies having biomarkers, including lymphocyte, platelets, D-dimer, lactate dehydrogenase (LDH), C reactive protein (CRP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine, procalcitonin (PCT) and creatine kinase (CK), and describing outcomes were selected with the consensus of three independent reviewers. MAIN OUTCOME MEASURES: Composite poor outcomes include intensive care unit admission, oxygen saturation <90%, invasive mechanical ventilation utilisation, severe disease, in-hospital admission and mortality. The OR and 95% CI were obtained and forest plots were created using random-effects models. Publication bias and heterogeneity were assessed by sensitivity analysis. RESULTS: 32 studies with 10 491 confirmed COVID-19 patients were included. We found that lymphopenia (pooled-OR: 3.33 (95% CI: 2.51-4.41); p<0.00001), thrombocytopenia (2.36 (1.64-3.40); p<0.00001), elevated D-dimer (3.39 (2.66-4.33); p<0.00001), elevated CRP (4.37 (3.37-5.68); p<0.00001), elevated PCT (6.33 (4.24-9.45); p<0.00001), elevated CK (2.42 (1.35-4.32); p=0.003), elevated AST (2.75 (2.30-3.29); p<0.00001), elevated ALT (1.71 (1.32-2.20); p<0.00001), elevated creatinine (2.84 (1.80-4.46); p<0.00001) and LDH (5.48 (3.89-7.71); p<0.00001) were independently associated with higher risk of poor outcomes. CONCLUSION: Our study found a significant association between lymphopenia, thrombocytopenia and elevated levels of CRP, PCT, LDH, D-dimer and COVID-19 severity. The results have the potential to be used as an early biomarker to improve the management of COVID-19 patients, by identification of high-risk patients and appropriate allocation of healthcare resources in the pandemic.

Five-year follow-up of patients receiving imatinib for chronic myeloid leukemia.

BACKGROUND: The cause of chronic myeloid leukemia (CML) is a constitutively active BCR-ABL tyrosine kinase. Imatinib inhibits this kinase, and in a short-term study was superior to interferon alfa plus cytarabine for newly diagnosed CML in the chronic phase. For 5 years, we followed patients with CML who received imatinib as initial therapy. METHODS: We randomly assigned 553 patients to receive imatinib and 553 to receive interferon alfa plus cytarabine and then evaluated them for overall and event-free survival; progression to accelerated-phase CML or blast crisis; hematologic, cytogenetic, and molecular responses; and adverse events. RESULTS: The median follow-up was 60 months. Kaplan-Meier estimates of cumulative best rates of complete cytogenetic response among patients receiving imatinib were 69% by 12 months and 87% by 60 months. An estimated 7% of patients progressed to accelerated-phase CML or blast crisis, and the estimated overall survival of patients who received imatinib as initial therapy was 89% at 60 months. Patients who had a complete cytogenetic response or in whom levels of BCR-ABL transcripts had fallen by at least 3 log had a significantly lower risk of disease progression than did patients without a complete cytogenetic response (P<0.001). Grade 3 or 4 adverse events diminished over time, and there was no clinically significant change in the profile of adverse events. CONCLUSIONS: After 5 years of follow-up, continuous treatment of chronic-phase CML with imatinib as initial therapy was found to induce durable responses in a high proportion of patients.

Transition to Independence: Characteristics and Outcomes of Mentored Career Development (KL2) Scholars at Clinical and Translational Science Award Institutions.

PURPOSE: To describe the transition from mentored to independent research funding for clinical and translational scholars supported by institutional KL2 Mentored Career Development programs. METHOD: In 2013, faculty leaders at Clinical and Translational Science Award institutions completed an online survey, reporting characteristics of scholars in their KL2 programs from 2006 to 2013. The primary outcome variable was a report that the scholar had received independent funding as a principal investigator. Data analysis included descriptive summaries and mixed-effects regression models. RESULTS: Respondents from 48 institutions (of 62 eligible; 77%) provided information about 914 KL2 scholars. Of those, 620 (68%) were medical doctors, 114 (12%) had other clinical training, and 177 (19%) were nonclinician PhDs. Fifty-three percent (487) were female; 12% (108/865) were members of racial or ethnic groups underrepresented in medicine (URM). After completing KL2 training, 96% (558/582) remained engaged in research. Among scholars who completed KL2 training two or more years earlier, 39% (149/374) received independent funding. Independent funding was from non-National Institutes of Health (NIH) sources (120 scholars) more often than from NIH (101 scholars). The odds of a nonclinician attaining independent funding were twice those of a clinician (odds ratio 2.05; 95% confidence interval 1.11-3.78). Female and URM scholars were as likely as male and non-URM scholars to attain independent funding. CONCLUSIONS: KL2 programs supported the transition to independent funding for clinical and translational scientists. Female and URM scholars were well represented. Future studies should consider non-NIH funding sources when assessing the transition to research independence.

An analysis of current neutropenia therapies, including pegfilgrastim.

Currently, 2 granulocyte colony-stimulating factors are available in the United States--filgrastim and pegfilgrastim. In patients receiving chemotherapy for solid tumors, lymphoma, and acute myelogenous leukemia, these agents reduce the duration of severe neutropenia, decrease the incidence of febrile neutropenia, and facilitate on-time delivery of scheduled doses of chemotherapy. In addition, substantial data document the benefits of using these agents in patients undergoing peripheral blood progenitor cell mobilization and in patients who have undergone bone marrow transplantation or peripheral blood progenitor cell transplantation. Recent studies suggest that for all of these indications, the efficacy of pegfilgrastim, the newest agent, is comparable to or greater than that of filgrastim. Like filgrastim, pegfilgrastim is generally well tolerated. An important advantage of pegfilgrastim, however, is its once-per-cycle schedule of administration. Patients and health care providers are likely to prefer the administration schedule of pegfilgrastim to the daily administration schedule required with the use of filgrastim. Furthermore, the more convenient schedule of pegfilgrastim may be associated with greater treatment adherence and increased patient quality of life.

Understanding Career Success and Its Contributing Factors for Clinical and Translational Investigators.

PURPOSE: To understand the factors that facilitate career success for career development awardees in clinical and translational science and reconceptualize understand ing of career success for this population. METHOD: In 2013-2014, the authors conducted semistructured interviews with former NIH KL2 or K12 scholars from nine Clinical and Translational Science Award-funded institutions. Participants either had or had not secured independent funding at least two years after the end of their last K award. Questions covered the factors that facilitate or hinder junior investigators' transition to independent funding. Interviews were recorded and transcribed, and the transcripts were analyzed thematically. RESULTS: Forty individuals participated, with equal representation by men and women and by independently and not independently funded investigators. Personal factors that facilitated success included networks, persistence and resilience, initiative, autonomy, and personal and professional balance. Organizational factors included appropriate mentorship, protected research time, and institutional resources and support.Even independently funded participants described challenges regarding career direction. Five participants without independent funding modeled a broad spectrum of successful career paths, having assumed leadership positions not reliant on grant funding. Alternative definitions of career success included improving public health, enjoying work, seeing mentees succeed, and receiving external acknowledgment of successes. CONCLUSIONS: Awareness of the factors that facilitate or hinder career success can help junior faculty, mentors, and institutional leaders support career development in clinical and translational science. New definitions of career success are needed, as are career paths for faculty who want to engage in research in roles other than principal investigator.

Benefits of epoetin alfa in anemic breast cancer patients receiving chemotherapy.

Breast cancer patients receiving chemotherapy often exhibit anemia, which contributes to symptoms such as fatigue, compromising quality of life (QOL). The present subset analysis assessed the effects of recombinant human erythropoietin (rHuEPO, epoetin alfa) on anemia and QOL in approximately 1300 patients with breast cancer, who were derived from 3 large, community-based clinical trials of epoetin alfa in anemic chemotherapy patients with various malignancies. Epoetin alfa effectively and safely corrected anemia and improved QOL scores on the Linear Analogue Self-Assessment, which measures energy, ability to perform daily activities, and QOL. Clinical, laboratory, and QOL improvements were qualitatively and quantitatively similar to those reported in the larger populations with various tumor types. The efficacy and safety of epoetin alfa did not vary according to dosing frequency (1 vs. 3 times weekly). Epoetin alfa is, therefore, effective and safe in the management of anemia in patients with breast cancer treated with chemotherapy.

Clinical benefits of epoetin alfa therapy in patients with lung cancer.

A retrospective subset analysis of anemic lung cancer patients who participated in three large, multicenter, community-based studies of 3-times-weekly (TIW) or once-weekly (QW) recombinant human erythropoietin (r-HuEPO, epoetin alfa) as an adjunct to chemotherapy was conducted. Patients were treated with epoetin alfa 150 U/kg in the first TIW study and with 10,000 U subcutaneously in the other study, with doubling of the dose if hemoglobin (Hb) response was inadequate. Patients in the QW study received epoetin alfa 40,000 U subcutaneously, which could be increased to 60,000 U. The maximum treatment duration for all three studies was 16 weeks. A total of 1748 lung cancer patients were evaluable for hematopoietic response; 1298 were evaluable for analyses of energy and 1300 were evaluable for analyses of activity and overall quality of life (QOL), as measured by the linear analogue scale assessment (LASA). Within 2 months of therapy, TIW and QW epoetin alfa therapy resulted in significant increases in Hb levels, decreases in transfusion requirements, and improvements in self-reported LASA scores. Increased Hb levels and reduced transfusion rates were demonstrated in the individual studies and in the analysis of data pooled from all three studies. Improvements in QOL parameters were significantly correlated with increased Hb levels. Epoetin alfa was well tolerated in all studies. The clinical benefits and safety profiles of the TIW and the QW schedules appear to be similar. In addition, the QW schedule provides greater convenience to patients and physicians alike. Given the high incidence of anemia and transfusion utilization in patients presenting with lung cancer, epoetin alfa is an effective strategy for correcting anemia in these patients, thereby improving their energy levels, activity levels, and overall QOL.

Prospective cohort study of the circadian rhythm pattern in allogeneic sibling donors undergoing standard granulocyte colony-stimulating factor mobilization.

INTRODUCTION: Prior in vivo murine studies suggest circadian oscillations for hematopoietic stem cell release, which are maintained following administration of granulocyte colony-stimulating factor (G-CSF) or plerixafor. Furthermore, retrospective data analysis of healthy donors who underwent G-CSF-induced mobilization demonstrated significantly increased CD34(+) cell yields when collected in the afternoon compared with the morning. METHODS: A prospective study was conducted to directly examine the number of peripheral blood CD34(+) and CD34(+)CD38- progenitor/stem cells at baseline and then every 6 hours for 24 hours on days 4 to 5 of G-CSF (10 µg/kg/day in the morning) mobilization in 11 allogeneic donors. Data were analyzed using mixed-model analysis of repeated measures. RESULTS: Whereas we observed a significant increase in CD34(+) cell counts toward the evening, counts were then sustained on the morning of day 5. The correlation between CD34(+)CD38- cell counts and the less defined CD34(+) populations was weak. CONCLUSIONS: Our results suggest that the pharmacodynamic activity and timing of G-CSF may alter endogenous progenitor rhythms. Donor age, medical history, and medications may also impact circadian rhythm. Further studies should examine the circadian rhythm at the peak of G-CSF mobilization and should consider potential confounders such as the time of G-CSF administration and the age of the subjects.

Phase 2 trial of the histone deacetylase inhibitor romidepsin for the treatment of refractory multiple myeloma.

BACKGROUND: Epigenetic dysregulation is a hallmark of cancer, including multiple myeloma. Inhibitors of histone deacetylases (HDACs) induce DNA hyperacetylation by inhibiting removal of acetyl groups from amino tails on histone proteins, thereby uncoiling condensed chromatin favoring transcription of silenced genes, including tumor suppressor genes. Romidepsin is an HDAC inhibitor that exhibits antiproliferative and apoptotic effects against multiple myeloma cell lines. METHODS: A phase 2 trial was performed of romidepsin in patients with multiple myeloma who were refractory to standard therapy. Treatment was comprised of romidepsin (13 mg/m²) given as a 4-hour intravenous infusion on Days 1, 8, and 15 every 28 days). Thirteen patients received a median of 2 cycles of therapy (range, 1-7 cycles). RESULTS: Although no patients had an objective response, 4 of 12 patients with secretory myeloma exhibited evidence of M-protein stabilization, and several other patients experienced improvement in bone pain and resolution of hypercalcemia. CONCLUSIONS: The results of the current study demonstrate that romidepsin, as a single agent, is unlikely to be associated with a response rate of ≥30% in patients with refractory myeloma, although there was some clinical evidence suggesting a biological effect associated with therapy.

Assessing symptom burden using the M. D. Anderson symptom inventory in patients with chemotherapy-induced anemia: results of a multicenter, open-label study (SURPASS) of patients treated with darbepoetin-alpha at a dose of 200 microg every 2 weeks.

BACKGROUND: Patients with cancer who are receiving chemotherapy often experience chemotherapy-induced anemia (CIA), which is associated with symptoms that reduce quality of life. The M. D. Anderson Symptom Inventory (MDASI) is a brief, self-rating assessment scale that measures the severity of core symptoms and symptom interference with function. The current study used the MDASI to prospectively assess the correlation between hemoglobin and self-perceived cancer-related symptoms in a large patient population with CIA who were receiving darbepoetin-alpha at a dose of 200 mug every 2 weeks. METHODS: Eligible patients enrolled in this multicenter, open-label study were age > or =18 years, had a nonmyeloid malignancy, were receiving multicycle chemotherapy, and were anemic (hemoglobin < or = 11 g/dL). Hemoglobin was measured every 2 weeks; the MDASI was administered weekly. For hemoglobin-based endpoints, patients were stratified by baseline hemoglobin (< 10 g/dL or > or =10 g/dL). RESULTS: Of 2422 enrolled patients, 2401 received > or =1 dose of darbepoetin-alpha. Eighty percent of patients (95% confidence limit, 78-82 patients) achieved target hemoglobin levels (> or =11 g/dL) during the study. Patients with a baseline hemoglobin < 10 g/dL had a greater increase in hemoglobin, took longer to achieve the target hemoglobin, and received more red blood cell transfusions than patients with a baseline hemoglobin > or =10 g/dL. The percentage of patients with moderate to severe MDASI scores (> or =5 points) for fatigue, distress, loss of appetite, disturbed sleep, and interference with function was reduced during the study. Improvement in symptom burden was associated with an increase in hemoglobin concentration. CONCLUSIONS: Treatment with darbepoetin-alpha at a dose of 200 mug every 2 weeks is associated with improvement in symptom burden as measured by the MDASI, a simple tool that may improve symptom management for cancer patients with CIA.
