RESUMO
This study investigates the association between circulating microRNA (miRNA) expression and cardiovascular adverse events (CVAE) in multiple myeloma (MM) patients treated with a carfilzomib (CFZ)-based regimen. A cohort of 60 MM patients from the Prospective Observation of Cardiac Safety with Proteasome Inhibitor (PROTECT) study was analyzed. Among these, 31 patients (51.6%) developed CVAE post-CFZ treatment. The Taqman OpenArray Human microRNA panels were used for miRNA profiling. We identified 13 differentially expressed miRNAs at baseline, with higher expressions of miR-125a-5p, miR-15a-5p, miR-18a-3p, and miR-152-3p and lower expression of miR-140-3p in patients who later developed CVAE compared to those free of CVAE, adjusting for age, gender, race, and higher B-type natriuretic peptide levels. We also identified three miRNAs, including miR-150-5p, that were differentially expressed in patients with and without CVAE post-treatment. Additionally, five miRNAs responded differently to CFZ treatment in CVAE vs. non-CVAE patients, including significantly elevated post-treatment expression of miR-140-3p and lower expressions of miR-598, miR-152, miR-21, and miR-323a in CVAE patients. Pathway enrichment analysis highlighted the involvement of these miRNAs in cardiovascular diseases and vascular processes. These findings suggest that specific miRNAs could serve as predictive biomarkers for CVAE and provide insights into the underlying mechanisms of CFZ-CVAE. Further investigation is warranted before these findings can be applied in clinical settings.

OBJECTIVES: Patients with multiple myeloma (MM) enrolled in randomized control trials (RCTs) discontinue treatment for various reasons; however, no prior study has analyzed reasons for discontinuation. We performed a systematic review of MM RCTs to investigate reasons for treatment discontinuation, imbalances between trial cohorts, and reporting practices. METHODS: A comprehensive search for RCTs in MM from 2015 to 2021 identified 45 studies meeting inclusion criteria. RESULTS: Of 21 236 randomized patients, 10 161 (47.8%) discontinued therapy by primary endpoint ascertainment. Causes of discontinuation included progression (n = 4790; 22.6% of randomized patients); toxicity (n = 2569; 12.1%); patient/physician withdrawal (n = 1200; 5.7%) and death (n = 495; 2.3%). Of randomized patients, 20 914 (98.5%) were included in the RCT analysis. Imbalances of attrition, defined as trials with greater than 5% absolute difference in discontinuation rate for reasons other than death, progression, and toxicity between intervention and control arms, were found in 11 (24.4%) studies. CONCLUSIONS: Although progression is the most common reason for RCT treatment discontinuation in patients with MM, over 10% discontinued due to toxicity. Furthermore, 24.4% of trials showed substantial imbalances between trial cohorts; raising concern for informative censoring and emphasizes the importance of detailed characterization of withdrawal in MM RCTs.

BACKGROUND: The plasma cell disorders (PCDs), multiple myeloma (MM), and light-chain amyloidosis (AL) are disproportionately diseases of older adults, whose care may be complicated by frailty associated with advancing age. We sought to evaluate the prevalence of functional deficits and symptoms in a cohort of persons with PCDs and associations of demographic, disease-related, functional, and psychosocial measures with quality of life (QoL). PATIENTS AND METHODS: Adults with PCDs were recruited into an observational registry in 2018-2020. Patients completed a functional assessment and European Organization for Research and Treatment of Cancer QoL questionnaire (QLQ-C30). Associations of covariates of interest with QoL were evaluated via univariate linear regression. RESULTS: Among 121 adults, the mean age was 68.6. Diagnoses were 74% MM, 14% AL, 7% both MM and AL, and 5% other PCDs. The median time from diagnosis was 34.9 months. Median lines of therapy were 2, with 11% having received ≥4th-line therapy.Patients with functional deficits had lower mean QoL scores: dependence in IADLs (66.3 vs. 79.9, P = .001) and recent falls (56.7 vs. 76.8, P = .001). Patients ≤6 months from diagnosis had lower QoL (66.7) than those ≥2 years from diagnosis (77.3, P = .03). However, patients on later lines of therapy (≥4th-line) had lower QoL (62.2) than those on 1st-line treatment (76.0, P = .04). CONCLUSIONS: Patients with physical impairments and more advanced PCDs had lower QoL than those without deficits or earlier in their disease course. Early identification of physical impairments may facilitate interventions that mitigate these deficits and thereby improve QoL for patients with PCDs.

Patients with hematologic malignancies are particularly vulnerable to infections due to underlying humoral and cellular immune dysfunction, cytotoxic chemotherapy regimens, advanced age, and the presence of comorbid conditions. Infection from severe acute respiratory syndrome coronavirus 2, the causative agent of the COVID-19 pandemic, has become a leading cause of death globally and has disproportionally affected this high-risk population. Here, we review the cumulative evidence demonstrating worse outcomes for patients with hematologic malignancies when compared to patients with solid tumors and the general population. We examine risk factors shared with the general population (age, sex, comorbid conditions, and race) and those that are cancer-specific (cytotoxic chemotherapy, progressive disease, and cancer type), all of which confer an increased risk of severe COVID-19. Despite the historical exclusion of cancer patients from COVID-19 therapy trials, we review the emerging evidence that patients with hematologic malignancies benefit from specific treatments such as convalescent plasma. Although COVID-19 vaccines are significantly less effective in this patient population, encouraging results are observed in a subset of these patients after receiving a booster dose.

BACKGROUND: Data on patients with COVID-19 who have cancer are lacking. Here we characterise the outcomes of a cohort of patients with cancer and COVID-19 and identify potential prognostic factors for mortality and severe illness. METHODS: In this cohort study, we collected de-identified data on patients with active or previous malignancy, aged 18 years and older, with confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection from the USA, Canada, and Spain from the COVID-19 and Cancer Consortium (CCC19) database for whom baseline data were added between March 17 and April 16, 2020. We collected data on baseline clinical conditions, medications, cancer diagnosis and treatment, and COVID-19 disease course. The primary endpoint was all-cause mortality within 30 days of diagnosis of COVID-19. We assessed the association between the outcome and potential prognostic variables using logistic regression analyses, partially adjusted for age, sex, smoking status, and obesity. This study is registered with ClinicalTrials.gov, NCT04354701, and is ongoing. FINDINGS: Of 1035 records entered into the CCC19 database during the study period, 928 patients met inclusion criteria for our analysis. Median age was 66 years (IQR 57-76), 279 (30%) were aged 75 years or older, and 468 (50%) patients were male. The most prevalent malignancies were breast (191 [21%]) and prostate (152 [16%]). 366 (39%) patients were on active anticancer treatment, and 396 (43%) had active (measurable) cancer. At analysis (May 7, 2020), 121 (13%) patients had died. In logistic regression analysis, independent factors associated with increased 30-day mortality, after partial adjustment, were: increased age (per 10 years; partially adjusted odds ratio 1·84, 95% CI 1·53-2·21), male sex (1·63, 1·07-2·48), smoking status (former smoker vs never smoked: 1·60, 1·03-2·47), number of comorbidities (two vs none: 4·50, 1·33-15·28), Eastern Cooperative Oncology Group performance status of 2 or higher (status of 2 vs 0 or 1: 3·89, 2·11-7·18), active cancer (progressing vs remission: 5·20, 2·77-9·77), and receipt of azithromycin plus hydroxychloroquine (vs treatment with neither: 2·93, 1·79-4·79; confounding by indication cannot be excluded). Compared with residence in the US-Northeast, residence in Canada (0·24, 0·07-0·84) or the US-Midwest (0·50, 0·28-0·90) were associated with decreased 30-day all-cause mortality. Race and ethnicity, obesity status, cancer type, type of anticancer therapy, and recent surgery were not associated with mortality. INTERPRETATION: Among patients with cancer and COVID-19, 30-day all-cause mortality was high and associated with general risk factors and risk factors unique to patients with cancer. Longer follow-up is needed to better understand the effect of COVID-19 on outcomes in patients with cancer, including the ability to continue specific cancer treatments.

Immunomodulatory drugs (IMiDs) have improved survival of patients with multiple myeloma (MM) and comprise the therapeutic backbone at all phases of therapy. Although well-tolerated, IMiDs increase rates of venous thromboembolism (VTE). In this phase IV, single-arm pilot study, fifty patients with MM on IMiDs received apixaban 2·5 mg orally twice daily for primary prevention of VTE and were prospectively monitored for six months. The primary safety outcomes were rates of major haemorrhage and clinically relevant non-major haemorrhage over six months. The primary efficacy outcome was the rate of symptomatic VTE over six months. IMiDs used were lenalidomide (58%) or pomalidomide (42%). During the six-month evaluation period, no patients experienced major haemorrhage or VTE. Three patients experienced clinically relevant, non-major haemorrhage which was managed medically, and all were able to resume apixaban. One patient stopped therapy shortly after initiation due to an allergic reaction to apixaban. No patients experienced stroke, myocardial infarction, or death. In this pilot study, low-dose apixaban was safe and well-tolerated as a primary prevention therapy of VTE for patients with MM receiving IMiDs. Further studies are needed to validate low-dose apixaban as a standard primary prevention anti-thrombotic strategy for patients with MM receiving IMiDs.

Anti-programmed cell death protein-1 (anti-PD-1) therapy has greatly improved outcomes of patients with melanoma; however, many fail to respond. Although preclinical studies suggest a potentially synergistic relationship with anti-PD-1 therapy and certain concurrent medications, their clinical role remains unclear. Here, we retrospectively evaluated the use of nonsteroidal anti-inflammatory drugs (NSAIDs) and other drugs in 330 patients with melanoma treated with anti-PD-1 therapy from four academic centers. In the cohort, 37% of patients used NSAIDs including aspirin (acetylsalicylic acid; ASA; 47%), cyclooxygenase (COX)-2 inhibitors (2%), and non-ASA/nonselective COX inhibitor NSAIDs (59%). The objective response rates (ORRs) were similar in patients with NSAID (43.4%) and no NSAID (41.3%) use with no significant difference in overall suvival (OS). There was a trend toward improved progression-free survival (PFS) in patients who took NSAIDs (median PFS: 8.5 vs. 5.2 months; p = .054). Most patients (71.3%) took NSAIDs once daily or as needed. Multivariate analysis did not reveal an association with NSAID use with ORR, PFS, or OS. Concurrent use of metformin or beta blockers did not affect ORR, PFS, or OS. Our study found no conclusive association of concurrent NSAID or other medication use with improved outcomes in patients with melanoma treated with anti-PD-1 therapy. Larger and more systematic analysis is required to confirm these findings.

BACKGROUND: Acetaminophen and diphenhydramine are routinely administered to prevent febrile non-hemolytic and allergic blood transfusion reactions despite multiple randomized controlled trials demonstrating that this practice lacks efficacy. As a result, patients are exposed to the adverse effects of these medications and their financial burdens with no expected benefit. The aim of this study was to quantify the frequency and cost of transfusion premedications in patients with acute myeloid leukemia (AML). STUDY DESIGN AND METHODS: This was a retrospective study of patients with AML admitted to Vanderbilt University Medical Center (VUMC) for induction chemotherapy between January 2008 and December 2016. Data were collected on the number of platelet and packed red blood cell (PRBC) transfusions each patient received during the initial inpatient encounter for AML, as well as on the administration of premedications prior to each transfusion. RESULTS: During the 9-year study period, 948 AML patients received a total of 19,820 transfusions. Of these, 30% were preceded by oral diphenhydramine, 8% by intravenous diphenhydramine, and 39% by oral acetaminophen. The percentage of patients that received a transfusion preceded by a premedication increased over the study period (p = 0.03), as did the percentage of transfusions preceded by a premedication (p = 0.02). The total unadjusted cost of pre-transfusion medications to the institution during the study period was $50,309.77, or $52.67 per patient with AML. The cost of premedications per patient did not increase over the study period (p = .45). CONCLUSIONS: Routine transfusion premedication administration is common in AML patients and not well-supported by available evidence.
RESUMO
BACKGROUND: Obesity has been linked to increased mortality in several cancer types; however, the relation between obesity and survival outcomes in metastatic melanoma is unknown. The aim of this study was to examine the association between body-mass index (BMI) and progression-free survival or overall survival in patients with metastatic melanoma who received targeted therapy, immunotherapy, or chemotherapy. METHODS: This retrospective study analysed independent cohorts of patients with metastatic melanoma assigned to treatment with targeted therapy, immunotherapy, or chemotherapy in randomised clinical trials and one retrospective study of patients treated with immunotherapy. Patients were classified according to BMI, following the WHO definitions, as underweight, normal, overweight, or obese. Patients without BMI and underweight patients were excluded. The primary outcomes were the associations between BMI and progression-free survival or overall survival, stratified by treatment type and sex. We did multivariable analyses in the independent cohorts, and combined adjusted hazard ratios in a mixed-effects meta-analysis to provide a precise estimate of the association between BMI and survival outcomes; heterogeneity was assessed with meta-regression analyses. Analyses were done on the predefined intention-to-treat population in the randomised controlled trials and on all patients included in the retrospective study. FINDINGS: The six cohorts consisted of a total of 2046 patients with metastatic melanoma treated with targeted therapy, immunotherapy, or chemotherapy between Aug 8, 2006, and Jan 15, 2016. 1918 patients were included in the analysis. Two cohorts containing patients from randomised controlled trials treated with targeted therapy (dabrafenib plus trametinib [n=599] and vemurafenib plus cobimetinib [n=240]), two cohorts containing patients treated with immunotherapy (one randomised controlled trial of ipilimumab plus dacarbazine [n=207] and a retrospective cohort treated with pembrolizumab, nivolumab, or atezolizumab [n=331]), and two cohorts containing patients treated with chemotherapy (two randomised controlled trials of dacarbazine [n=320 and n=221]) were classified according to BMI as normal (694 [36%] patients), overweight (711 [37%]), or obese (513 [27%]). In the pooled analysis, obesity, compared with normal BMI, was associated with improved survival in patients with metastatic melanoma (average adjusted hazard ratio [HR] 0·77 [95% CI 0·66-0·90] for progression-free survival and 0·74 [0·58-0·95] for overall survival). The survival benefit associated with obesity was restricted to patients treated with targeted therapy (HR 0·72 [0·57-0·91] for progression-free survival and 0·60 [0·45-0·79] for overall survival) and immunotherapy (HR 0·75 [0·56-1·00] and 0·64 [0·47-0·86]). No associations were observed with chemotherapy (HR 0·87 [0·65-1·17, pinteraction=0·61] for progression-free survival and 1·03 [0·80-1·34, pinteraction=0·01] for overall survival). The association of BMI with overall survival for patients treated with targeted and immune therapies differed by sex, with inverse associations in men (HR 0·53 [0·40-0·70]), but no associations observed in women (HR 0·85 [0·61-1·18, pinteraction=0·03]). INTERPRETATION: Our results suggest that in patients with metastatic melanoma, obesity is associated with improved progression-free survival and overall survival compared with those outcomes in patients with normal BMI, and that this association is mainly seen in male patients treated with targeted or immune therapy. These results have implications for the design of future clinical trials for patients with metastatic melanoma and the magnitude of the benefit found supports further investigation of the underlying mechanism of these associations.

Light chain amyloidosis (AL) results in tissue deposition of misfolded proteins, causing organ dysfunction. In an era of modern therapies, such as bortezomib, reassessment of the benefit of autologous hematopoietic cell transplantation (AHCT) should be considered. In this study, we compared outcomes between patients with AL receiving chemotherapy alone (CT) and those undergoing AHCT. Seventy-four patients with AL were analyzed retrospectively. Two cohorts of patients were studied, those receiving CT (n = 31) and those undergoing AHCT (n = 43). Of the 43 patients in the AHCT cohort, 29 received induction chemotherapy before AHCT, whereas 14 proceeded straight to AHCT without induction therapy. Compared with the CT cohort, patients in the AHCT cohort were younger and had higher ejection fractions, lower brain natriuretic peptide levels, and more severe proteinuria. The majority (87%) of patients in the CT cohort received bortezomib-based treatment. Transplantation-related mortality (TRM) was 7%. Patients receiving AHCT were more likely to achieve complete or very good partial response (P = .048). The median progression-free survival (PFS) and overall survival (OS) were superior in the AHCT cohort (not reached versus 9 months; P < .01 and 74 months versus 8 months; P = .03, respectively). Multivariable analysis demonstrated that improved PFS (hazard ratio, 3.86; 95% confidence interval [CI] 1.3 to 11.5; P = .02) and OS (hazard ratio, 5.6; 95% CI, 1.9 to 16; P < .001) were associated with use of AHCT compared with CT. Patients in the AHCT cohort had deeper and longer durations of response, with superior PFS and OS, compared with those in the CT cohort. Despite the limitations of this study, AHCT should be considered for eligible patients with AL at experienced transplantation centers that can offer this therapy with a low risk of TRM.

BACKGROUND: Monoclonal antibodies (mAb) targeting PD-1/PD-L1 have revolutionized melanoma treatment, yet data regarding effectiveness and tolerability across age groups is limited. We sought to determine the impact of age on overall survival (OS), progression-free survival (PFS), and rates of immune-mediated toxicities in patients treated with anti-PD-1/anti-PD-L1 mAb at two academic medical centers. METHODS: We retrospectively collected data on all patients with metastatic melanoma treated with anti-PD-1/PD-L1 mAb between May 2009 and April 2015. We used Kaplan-Meier and Cox regression analyses to assess OS and PFS and identify factors associated with these outcomes. We also compared rates of autoimmune toxicity across age groups. RESULTS: Of 254 patients, 57 (22.4%) were <50 years old, 85 (33.5%) were age 50-64, 65 (25.6%) were age 65-74, and 47 (18.5%) were ≥75 years. Across age groups, no differences existed in median OS (age <50: 22.9 months, age 50-64: 25.3 months, age 65-74: 22.0 months, age ≥75: 24.3 months) or PFS (age <50: 4.1 months, age 50-64: 6.5 months, age 65-74: 5.4 months, age ≥75: 7.9 months). The presence of liver metastases and elevated pre-treatment lactate dehydrogenase (LDH) were associated with reduced OS. Presence of liver metastasis, pretreatment LDH, BRAF mutation, and type of melanoma correlated with PFS. Overall, 110 patients (43.3%) experienced immune-mediated toxicities; 25 (9.8%) had colitis and 26 (10.2%) had endocrine toxicity. Rates of colitis, hepatitis, and pneumonitis did not differ across age groups. CONCLUSION: We demonstrated that patients could safely tolerate anti-PD1/PDL-1 mAb therapy and achieve similar outcomes regardless of their age. IMPLICATIONS FOR PRACTICE: Immunotherapy has revolutionized treatment for patients with metastatic melanoma, yet data are lacking regarding the effectiveness and tolerability of these treatments for older patients. In this study, we demonstrated that patients with melanoma safely tolerate immunotherapy and achieve similar outcomes regardless of their age. Specifically, we utilized data from two academic cancer centers and found no significant difference in overall survival, progression free survival, or immune-related toxicities, other than arthritis, across age groups. As the population ages, studies such as this will become critical to help us understand how best to treat older adults with cancer.

Hematopoietic stem cell transplantation (HSCT) has an integral role in the treatment of malignant and nonmalignant diseases. Long-term complications after HSCT have been well established and include graft-versus-host disease (GVHD), conditioning regimen-related toxicities, disease relapse, and infections. Immune-mediated phenomena are increasingly described after HSCT with clinically significant sequelae. Diagnosis is challenging because of features that overlap with other commonly reported post-transplantation complications. Patients who experience immune-mediated disease after HSCT tend to have poor outcomes. Early recognition of immune-mediated complications is imperative to reduce preventable morbidity and mortality. This review looks at the currently available literature on pathogenesis, incidence, risk factors, treatment, and outcomes of immune-mediated disease (other than GVHD) after HSCT.

INTRODUCTION: The therapeutic landscape in relapsed/refractory multiple myeloma (RRMM) has changed rapidly, with twenty-two drug approvals since 2012. We characterized population-level trends in RRMM therapy selection, survival and cost outcomes associated with RRMM treatment over time. MATERIALS AND METHODS: Our cohort included adults diagnosed with multiple myeloma (MM) in the SEER-Medicare database from 2007-2017 who received at least one antimyeloma agent. MM-directed therapies and lines of therapy were identified. Changes in 2LT regimens over time were described. Trends in overall survival from 2LT initiation over time were analyzed using a Cox proportional hazards model adjusting for factors associated with survival in MM. Trends in mean inflation-adjusted cost per 12 months of 2LT were analyzed using JoinPoint analysis. RESULTS: A total of 9,822 patients met eligibility criteria, of whom 5,866 (59.7%) received 2LT. By 2018, 46% of 2LT regimens contained at least one agent approved in 2012 or later. Year of 2LT initiation was associated with improved overall survival (HR 0.78 per 5 years, 95% CI 0.74-0.84) after adjustment. Costs associated with 2LT increased over the study period, and the rate of cost increase increased significantly after 2012 (0.89%/year vs. 9.9%/year, P < .001), with higher total costs for regimens containing newer novel agents (mean $224,193 vs. $189,381, P < .001) CONCLUSION: Overall survival after initiation of 2LT has improved, however this has been accompanied by significant increases in costs of RRMM treatment, particularly for patients receiving newer novel agents. These findings provide useful context for existing and future drug approvals in RRMM.
RESUMO
Background: Initial insights into oncology clinical trial outcomes are often gleaned manually from conference abstracts. We aimed to develop an automated system to extract safety and efficacy information from study abstracts with high precision and fine granularity, transforming them into computable data for timely clinical decision-making. Methods: We collected clinical trial abstracts from key conferences and PubMed (2012-2023). The SEETrials system was developed with four modules: preprocessing, prompt modeling, knowledge ingestion and postprocessing. We evaluated the system's performance qualitatively and quantitatively and assessed its generalizability across different cancer types- multiple myeloma (MM), breast, lung, lymphoma, and leukemia. Furthermore, the efficacy and safety of innovative therapies, including CAR-T, bispecific antibodies, and antibody-drug conjugates (ADC), in MM were analyzed across a large scale of clinical trial studies. Results: SEETrials achieved high precision (0.958), recall (sensitivity) (0.944), and F1 score (0.951) across 70 data elements present in the MM trial studies Generalizability tests on four additional cancers yielded precision, recall, and F1 scores within the 0.966-0.986 range. Variation in the distribution of safety and efficacy-related entities was observed across diverse therapies, with certain adverse events more common in specific treatments. Comparative performance analysis using overall response rate (ORR) and complete response (CR) highlighted differences among therapies: CAR-T (ORR: 88%, 95% CI: 84-92%; CR: 95%, 95% CI: 53-66%), bispecific antibodies (ORR: 64%, 95% CI: 55-73%; CR: 27%, 95% CI: 16-37%), and ADC (ORR: 51%, 95% CI: 37-65%; CR: 26%, 95% CI: 1-51%). Notable study heterogeneity was identified (>75% I 2 heterogeneity index scores) across several outcome entities analyzed within therapy subgroups. Conclusion: SEETrials demonstrated highly accurate data extraction and versatility across different therapeutics and various cancer domains. Its automated processing of large datasets facilitates nuanced data comparisons, promoting the swift and effective dissemination of clinical insights.
RESUMO
As a treatment for relapsed or refractory multiple myeloma (MM), carfilzomib has been associated with a significant risk of cardiovascular adverse events (CVAE). The goals of our study were to evaluate the metabolomic profile of MM patients to identify those at high risk prior to carfilzomib treatment and to explore the mechanisms of carfilzomib-CVAE to inform potential strategies to protect patients from this cardiotoxicity. Global metabolomic profiling was performed on the baseline and post-baseline plasma samples of 60 MM patients treated with carfilzomib-based therapy, including 31 who experienced CVAE, in a prospective cohort study. Baseline metabolites and post-baseline/baseline metabolite ratios that differ between the CVAE and no-CVAE patients were identified using unadjusted and adjusted methods. A baseline metabolomic risk score was created to stratify patients. We observed a lower abundance of tauroursodeoxycholic acid (T-UDCA) in CVAE patients at baseline (odds ratio [OR] = 0.47, 95% confidence interval [CI] = 0.21-0.94, p = 0.044) compared with the no-CVAE patients. A metabolite risk score was able to stratify patients into three risk groups. The area under the receiver-operating curve of the model with clinical predictors and metabolite risk score was 0.93. Glycochenodeoxycholic acid (OR = 0.56, 95% CI = 0.31-0.87, p = 0.023) was significantly lower in post-baseline/baseline ratios of CVAE patients compared with no-CVAE patients. Following metabolomic analysis, we created a baseline metabolite risk score that can stratify MM patients into different risk groups. The result also provided intriguing clues about the mechanism of carfilzomib-CVAE and potential cardioprotective strategies.

INTRODUCTION: Geriatric assessment (GA)-guided supportive care programs have been successful in improving treatment outcomes for older adults with solid-organ cancers. This study aimed to evaluate the feasibility of a GA-guided supportive care program among older adults treated for multiple myeloma (MM). MATERIALS AND METHODS: The study utilized an existing registry of adults with plasma cell disorders at the University of North Carolina. Patients with MM, aged 60 or older, and having a GA-identified deficit in one or more problem area were offered referrals to supportive care resources during routine visits. Problem areas included physical function deficits, polypharmacy, and anxiety or depression. Patients with physical function deficits were offered referral to physical therapy (PT), those with polypharmacy to an Oncology Clinical Pharmacist Practitioner (CPP), and those with mental health symptoms to the Comprehensive Cancer Support Program (CCSP). RESULTS: Of the 58 individuals identified as having at least one deficit on the GA, PT was the most commonly identified relevant resource (79%), followed by CPP visits (57%). Among individuals that were offered referral(s) to at least one new supportive care resource, the acceptance rate was 50%. Referral acceptance rates were highest among those recommended for a CPP visit (55% of those approached) and lowest for CCSP (0%). DISCUSSION: The study examined the feasibility and acceptability of a referral program for supportive care resources among older adults with MM who have deficits on GA. The most commonly identified deficit was physical functioning, followed by polypharmacy and mental health. The study found that physical interventions and referrals to CPPs were the most accepted interventions. However, the low proportion of patients who accepted physical therapy referrals indicates the need for tailored and more personalized approaches. Further research is needed to explore the feasibility and impact of supportive care referral programs for older adults with MM.

In clinical practice medications are often interchanged in treatment protocols when a patient negatively reacts to their first line of therapy. Although switching between medications is common, clinicians often lack structured guidance when choosing the initial dose and frequency of a new medication, given the former with respect to risk of adverse events. In this paper we propose to establish this dose toxo-equivalence relationship using published clinical trial results with one or both drugs of interest via a Bayesian meta-analysis model that accounts for both within- and between-study variances. With the posterior parameter samples from this model, we compute median and 95% credible intervals for equivalent dose pairs of the two drugs that are predicted to produce equal rates of an adverse outcome, relying solely on study-level information. Via extensive simulations, we show that this approach approximates well the true dose toxo-equivalence relationship, considering different study designs, levels of between-study variance, and the inclusion/exclusion of nonconfounder/nonmodifier subject-level covariates in addition to study-level covariates. We compare the performance of this study-level meta-analysis estimate to the equivalent individual patient data meta-analysis model and find comparable bias and minimal efficiency loss in the study-level coefficients used in the dose toxo-equivalence relationship. Finally, we present the findings of our dose toxo-equivalence model applied to two chemotherapy drugs, based on data from 169 published clinical trials.
RESUMO
PURPOSE: Residents of communities facing social vulnerability (eg, poverty) have limited access to clinical trials, leaving them susceptible to experiencing poor health outcomes. We examined the association between North Carolina county-level social vulnerability and available multiple myeloma (MM) trials. METHODS: Using a novel data linkage between ClinicalTrials.gov, the 2019 American Community Survey, and the Centers for Disease Control and Prevention's Social Vulnerability Index, we investigated at the county level (1) availability of MM trial sites and (2) the relationship between Social Vulnerability Index and MM trial site availability using logistic regression. RESULTS: Between 2002 and 2021, 229 trials were registered across 462 nonunique trial sites in 34 counties. Nearly 50% of trial sites were in academic medical centers, 80% (n = 372) of all trials were industry-sponsored, 60% (n = 274) were early-phase, and 50% (n = 232) were for patients with relapsed or refractory MM. Counties with low as opposed to high poverty rates had six times greater odds of having ≥ 1 MM trial sites (odds ratio [OR], 5.60; 95% CI, 1.85 to 19.64; P = .004). Counties with the lowest percentage of Black Indigenous Persons of Color and non-native English speakers had 77% lower odds (OR, 0.23; 95% CI, 0.07 to 0.69; P = .011) of having ≥ 1 trial sites. The effect remained significant after accounting for the presence of five academic medical centers (n = 95; OR, 0.18; 95% CI, 0.05 to 0.6; P = .008) and adjustment for metropolitan, suburban, or rural status (OR, 0.25; 95% CI, 0.07 to 0.81; P = .025). CONCLUSION: Counties with the lowest poverty rates had more MM trial sites, whereas those with the lowest percentage of Black Indigenous Persons of Color populations had fewer MM trial sites. Multilevel efforts are needed to improve the availability and access to trials for socially vulnerable populations.
