Novel and replicated clinical and genetic risk factors for toxicity from high-dose methotrexate in pediatric acute lymphoblastic leukemia.

STUDY OBJECTIVE: Methotrexate (MTX) is a key component of treatment for high-risk pediatric acute lymphoblastic leukemia (ALL) but may cause acute kidney injury and prolonged hospitalization due to delayed clearance. The purpose of this study is to identify clinical and genetic factors that may predict which children are at risk for creatinine increase and prolonged MTX clearance. DESIGN: We conducted a single-center, retrospective cohort study of pediatric patients with ALL who received 4000-5000 mg/m2 of MTX. Measurements We performed germline genotyping to determine genetic ancestry and allele status for 49 single nucleotide polymorphisms (SNPs) identified from the literature as related to MTX disposition. Bayesian hierarchical ordinal regression models for creatinine increase and for prolonged MTX clearance were developed. MAIN RESULTS: Hispanic ethnicity, body mass index (BMI) < 3%, BMI between 85%-95%, and Native American genetic ancestry were found to be associated with an increased risk for creatinine elevation. Older age, Black race, and use of the intensive monitoring protocol were associated with a decreased risk for creatinine elevation. Older age, B- compared to T-ALL, and the minor alleles of rs2838958/SLC19A1 and rs7317112/ABCC4 were associated with an increased risk for delayed clearance. Black race, MTX dose reduction, and the minor allele of rs2306283/SLCO1B1 were found to be associated with a decreased risk for delayed clearance. CONCLUSIONS: These predictors of MTX toxicities may allow for more precise individualized toxicity risk prediction.

Treatment of Langerhans cell histiocytosis with subcutaneous cytarabine.

Patients with Langerhans cell histiocytosis (LCH) have been effectively treated with intravenous cytarabine. Intravenous or subcutaneous cytarabine infusions have been effective for leukemia patients, and pharmacokinetic studies have shown very similar blood levels of the drug with either route. We present three LCH patients treated with subcutaneous cytarabine either because intravenous access could not be maintained or due to patient refusal. One patient with pulmonary and skin LCH had a complete response. Another patient had a partial response of pulmonary and cutaneous lesions, but progressive bone disease. The third patient was treated for LCH-related cerebellar changes eight years after the diagnosis of isolated diabetes insipidus, with stable brain MRI for 5 years post-treatment. Subcutaneous cytarabine administration provides an alternative for patients with LCH in whom vascular access is not possible or practical, such as in some resource-limited circumstances.

Safety analysis of high-dose methotrexate in pediatric non-Hodgkin lymphomas.

High-dose methotrexate (HD-MTX) with rigorous supportive care is essential to the treatment of pediatric non-Hodgkin lymphomas (NHL). We describe the safety and tolerability of HD-MTX in patients with NHL treated at our center. In our cohort of 46 patients, the majority had at least one course of delayed clearance and/or creatinine elevation. Additionally, more than one-third of patients experienced an episode of grade ≥3 mucositis. Creatinine elevations and delayed clearance were independently associated with subsequent grade ≥3 mucositis. We advocate for greater availability of methotrexate monitoring to allow dose escalation of this essential modality around the world.

Clinical and demographic factors contributing to asparaginase-associated toxicities in children with acute lymphoblastic leukemia.

A total of 548 patients (age range: 1-22 years, 60.4% Hispanic, 55.8% male) diagnosed with acute lymphoblastic leukemia were reviewed for pegaspargase-associated hypersensitivity (14.8%), hyperbilirubinemia (9.7%), venous thromboembolism (VTE, 9.7%), and pancreatitis (5.3%). Odds ratios (OR) and 95% confidence intervals (CI) evaluated associations between clinical factors and each toxicity, cumulative number of toxicities, and toxicity clusters identified using k-mode analysis. Most (68.9%) did not experience any toxicity, 24.6% experienced one toxicity, and 6.3% two or more. Age >10 years was associated with hyperbilirubinemia (OR = 3.83; 95% CI: 1.64-8.95), pancreatitis (OR = 3.72; 95% CI: 1.29-10.68), VTE (OR = 4.65; 95% CI: 1.96-11.02), and cumulative toxicity burden (OR = 3.28, 95% CI: 1.97-5.47); high-risk therapy with hypersensitivity (OR 2.25; 95% CI 1.25-4.05); and overweight with cumulative toxicity burden (OR = 1.76, 95% CI: 1.20-2.57). Eight unique toxicity profiles were identified. Older age, overweight, and treatment intensity contribute to pegaspargase-associated toxicities.

Rising drug cost impacts on cost-effectiveness of 2 chemotherapy regimens for intermediate-risk rhabdomyosarcoma: A report from the Children's Oncology Group.

BACKGROUND: The Children's Oncology Group clinical trial for intermediate risk rhabdomyosarcoma randomized participants to a combination of vincristine, dactinomycin, and cyclophosphamide (VAC) alone or VAC alternating with vincristine plus irinotecan (VAC/VI). Clinical outcomes were similar, but toxicity profiles differed. This study estimates the cost differences between arms from the health care system's perspective. METHODS: A decision-analytic model was used to estimate the incremental cost-effectiveness ratio (ICER) of VAC versus VAC/VI. Protocol-required or recommended medications and laboratory studies were included. Costs were obtained from national databases or supporting literature and inflated to 2019 US dollars. Demographic and outcome data were obtained from the clinical trial and directed chart reviews. Life-years (LY) were estimated from life-expectancy tables and discounted by 3% annually. Probabilistic sensitivity analyses and alternative clinical scenarios identified factors driving costs. RESULTS: Mean direct medical costs of VAC and VAC/VI were $164,757 and $102,303, respectively. VAC was associated with an additional 0.97 LY and an ICER of $64,386/LY compared with VAC/VI. The ICER was sensitive to survival estimations and to alternative clinical scenarios including outpatient cyclophosphamide delivery (ICER $49,037/LY) or substitution of alternative hematopoietic growth factor schedules (ICER $73,191-$91,579/LY). Applying drug prices from 2012 decreased the total costs of VAC by 20% and VAC/VI by 15% because of changes in dactinomycin and pegfilgrastim prices. CONCLUSIONS: Neither arm was clearly more cost-effective. Pharmaceutical pricing and location of treatment drove costs and may inform future treatment decisions. Rising pharmaceutical costs added $30,000 per patient, a finding important for future drug-pricing policy decisions. LAY SUMMARY: Two chemotherapy regimens recently tested side-by-side for rhabdomyosarcoma had similar tumor outcomes, but different side effects. The health care costs of each regimen were compared; neither was clearly more cost-effective. However, the costs of each treatment changed dramatically with choices of supportive medicines and location of treatment. Costs of treatment rose by 15% to 20% because of rising US drug costs not associated with the clinical trial.

Novel risk factors for glucarpidase use in pediatric acute lymphoblastic leukemia: Hispanic ethnicity, age, and the ABCC4 gene.

BACKGROUND: Carboxypeptidase G2 (CPDG2 ; glucarpidase) is a rescue drug for patients at risk for kidney injury from high-dose methotrexate (MTX). As there are no strategies for predicting patients who will require CDPG2 , we evaluated the role of demographic, clinical, and genetic factors for CPDG2 use. PROCEDURE: Cases who received CPDG2 and controls who did not were identified by chart review of acute lymphoblastic leukemia (ALL) patients who received MTX doses between 1000 and 5000 mg/m2 between 2010 and 2017. We used multivariable Bayesian logistic regression to evaluate the association of CPDG2 use with demographic and clinical variables and, on a subset of patients, with genetic ancestry and 49 single nucleotide variants previously associated with MTX toxicity. RESULTS: We identified 423 patients who received 1592 doses of MTX. Of the 18 patients who received CPDG2 , 17 (94%) were Hispanic. No patients who received 1000 or 2000 mg/m2 of MTX received CPDG2 . Hispanic ethnicity (odds ratio: 4.68; 95% compatibility interval: 1.63-15.06) and older age (1.87 [1.17-3.17]) were associated with receiving CPDG2 . Of the 177 patients in the genomic cohort, 11 received CPDG2 . Each additional G allele of rs7317112 in ABCC4 increased the odds of requiring CPDG2 (3.10 [1.12-6.75]). Six other loci (NTRK1/rs10908521, TSG1/rs9345389, STT3B/rs1353327, SCLO1B1/rs4149056, GATA3/rs3824662, ARID5B/rs10821936) demonstrated probabilities of association between 88% and 97%. CONCLUSION: We demonstrated that demographic characteristics, including Hispanic ethnicity and age, are associated with CPDG2 use. Additionally, we provide evidence that inherited genetic variation is associated with risk of requiring CPDG2 . If validated in independent populations, this information could be leveraged to develop targeted toxicity prevention strategies for children with ALL.

Association of Rituximab Use With Adverse Events in Children, Adolescents, and Young Adults.

Importance: Rituximab is among the most frequently used immunotherapies in pediatrics. Few studies have reported long-term adverse events associated with its use for children. Objective: To describe the use of rituximab and to assess whether its use is associated with short- or long-term adverse events, infections, or time to immune reconstitution in a diverse group of young people. Design, Setting, and Participants: This retrospective cohort study included 468 patients aged younger than 21 years who received rituximab for diverse indications between October 1, 2010, and December 31, 2017, at Texas Children's Hospital, a large pediatric referral hospital. Patterns of adverse events, infections, and immune recovery are described. Data analyses were conducted from December 2019 to June 2020. Exposure: One or more doses of rituximab. Main Outcomes and Measures: Adverse drug events (eg, anaphylaxis), incidence of mild and severe infections, and time to recovery of B lymphocyte subset counts and immunoglobulin levels. Survival models and logistic regression analyses and were used to identify associated risk factors of infectious and noninfectious adverse drug events. Results: We identified 468 patients receiving at least 1 dose of rituximab. The total follow-up time was 11 713 person-months. Of the 468 patients, 293 (62.6%) were female, the median (interquartile range) age at receipt of dose was 14.3 (9.9-16.8) years, and 209 (44.7%) were self-reported White Hispanic. Adverse events associated with rituximab infusion occurred in 72 patients (15.4%), and anaphylaxis occurred in 17 patients (3.6%). Long-term adverse events, such as prolonged neutropenia and leukoencephalopathy, were absent. Infections occurred in 224 patients (47.9%); 84 patients (17.9%) had severe infections, and 3 patients (0.6%) had lethal infections. Concurrent use of intravenous chemotherapy, treatment of systemic lupus erythematosus, neutropenia, and use of intravenous immunoglobulin were associated with increased risk of infection. Among 135 patients (28.8%) followed up to B cell count recovery, CD19+ or CD20+ cell numbers normalized in a median of 9.0 months (interquartile range, 5.9-14.4 months) following rituximab use; 48 of 95 patients (51%) evaluated beyond a year had low-for-age B cell counts. Recovery of CD27+ memory B cell number occurred in a median of 15.7 months (interquartile range, 6.0-22.7 months). Among patients with normal baseline values, low immunoglobulin G (IgG) levels developed in 67 of 289 patients (23.2%) and low IgM levels in 118 of 255 patients (40.8%); of these patients evaluated beyond 12 months from rituximab, 16 of 117 (13.7%) had persistently low IgG and 37 (33.9%) of 109 had persistently low IgM. Conclusions and Relevance: Rituximab is well tolerated among young people and is associated with few serious adverse events, but infections are common, corresponding to a prolonged period of B cell count recovery often lasting for longer than a year. Further examination of strategies to prevent infections following rituximab should be pursued.

The Best Pharmaceuticals for Children Act and Pediatric Research Equity Act reach the age of majority-An oncology perspective.

The scarcity of adequate pediatric drug labeling information has long been problematic in the pediatric population, which may place children at risk for adverse drug effects. The ontogeny of infants, children, and adolescents over the course of the first two decades of life pose complex pharmacokinetic, dosing, administration, effectiveness, and toxicity-related questions that require specific investigation. Here, we review the history that led to the passage of the Best Pharmaceuticals for Children Act (BPCA) and Pediatric Research Equity Act (PREA), and provide commentary on issues relevant to pediatric oncology now and in the future.

Cerebrospinal Fluid Metabolomic Profiles Associated With Fatigue During Treatment for Pediatric Acute Lymphoblastic Leukemia.

CONTEXT: Cancer-related fatigue (CRF) is one of the most distressing and persistent symptoms reported during pediatric acute lymphoblastic leukemia (ALL) therapy; however, information on the pathways underlying CRF severity is limited. OBJECTIVES: We conducted global metabolomics profiling of cerebrospinal fluid (CSF) samples to provide insight into the underlying mechanisms of CRF. METHODS: Fatigue in pediatric ALL patients (2012-2017) was assessed during postinduction therapy approximately six months after diagnosis. Postinduction CSF was collected from 171 participants, comprising discovery (n = 86) and replication (n = 85) cohorts. We also conducted secondary validation using diagnostic CSF from 48 replication cohort participants. CSF metabolomic profiling was performed using gas chromatography-mass spectrometry (MS) and liquid chromatography-MS/MS. Kendall's rank correlation was used to evaluate associations between metabolite abundance and CRF. False discovery rate was used to account for multiple comparisons. RESULTS: Participants were 56% males and 59% Hispanic with a mean age at diagnosis of 8.5 years. A total of 274 CSF-derived metabolites were common to the discovery and replication cohorts. Eight metabolites were significantly associated with fatigue in the discovery cohort (P < 0.05), of which three were significant in the replication cohort, including false discovery rate-corrected associations with gamma-glutamylglutamine (Pcombined = 6.2E-6) and asparagine (Pcombined = 3.5E-4). Notably, the abundance of gamma-glutamylglutamine in diagnostic CSF samples was also significantly associated with fatigue (P = 0.0062). CONCLUSION: The metabolites identified in our assessment have been implicated in neurotransmitter transportation and glutathione recycling, suggesting that glutamatergic pathways or oxidative stress may contribute to ALL-associated CRF. This information could inform targeted therapies for reducing CRF in at-risk individuals.

Is high-risk neuroblastoma induction chemotherapy possible without G-CSF? A pilot study of safety and treatment delays in the absence of primary prophylactic hematopoietic growth factors.

BACKGROUND/OBJECTIVES: Standard supportive care during induction therapy for high-risk neuroblastoma (HR-NBL) includes primary prophylactic granulocyte colony-stimulating factor (G-CSF) aimed at limiting duration of neutropenia, reducing infection risk, and minimizing treatment delays. Preclinical models suggest that G-CSF promotes maintenance of neuroblastoma cancer stem cells and may reduce the efficacy of chemotherapy. This study's objective was to determine the safety and feasibility of administering induction chemotherapy without routine use of prophylactic G-CSF. DESIGN/METHODS: Children with newly diagnosed HR-NBL received six-cycle induction chemotherapy regimen without prophylactic G-CSF in four cycles. G-CSF was administered for stem cell mobilization after cycle 3 and granulocyte-monocyte colony-stimulating factor after cycle 5 prior to surgical resection of primary disease. The primary outcome measure was the incidence of grade 3 or higher infection. We hypothesized that the per patient infection rate would be comparable to our institutional baseline rate of 58% in patients with HR-NBL receiving induction chemotherapy with prophylactic growth factor support. The trial used an A'Hern single-stage design. RESULTS: Twelve patients with HR-NBL received 58 cycles of chemotherapy on study. Three patients completed the entire six-cycle regimen with no infections. Nine patients experienced grade 3 infections (bacteremia four, urinary tract infection two, skin/soft tissue infection three). No patients experienced grade 4 infections or required intensive care treatment for infection. CONCLUSION: A greater than expected number of serious bacterial infections were observed during administration of induction chemotherapy for HR-NBL without primary prophylactic G-CSF. These results support continued prophylactic administration growth factor during induction chemotherapy.

Do intravenous fluid substitutions influence methotrexate clearance? An unanticipated impact of an intravenous sodium bicarbonate drug shortage.

BACKGROUND: National drug shortages of essential medications for childhood cancer have increasingly posed a challenge in the treatment of patients. The efficacy of standardized supportive care practices to avoid treatment-related toxicities may be limited during these drug shortages. High-dose methotrexate (HDMTX) plays a critical role in modern treatment protocols for acute lymphoblastic leukemia and requires stringent supportive care measures to mitigate toxicity. As the result of a national intravenous (IV) sodium bicarbonate shortage, institutional standard HDMTX supportive care guidelines had to be modified. We describe the unanticipated consequences on HDMTX clearance. METHODS: We performed a retrospective chart review assessing the impact of alternative compositions of IV fluids on the mean 24-h methotrexate levels (Cpss ) of 25 patients receiving 76 total HDMTX infusions at Texas Children's Hospital Cancer Center from March to October 2017. During the sodium bicarbonate drug shortage, all patients received IV hydration consisting of either dextrose 5%, 0.45% normal saline (D5 ½ NS-Group A) or dextrose 5%, 0.2% normal saline (D5 » NS-Group B). RESULTS: Patients receiving a higher total sodium dose demonstrated significantly lower Cpss (25.36 ± 16.6 µMol) compared to patients receiving less sodium (53.9 ± 37.9 µMol; P < .001). CONCLUSIONS: Our report shows that in the setting of IV sodium bicarbonate shortage, the composition of hydration IV fluids may affect methotrexate clearance. Patient who received a higher sodium load had a lower 24-h methotrexate level. This demonstrates the potential for unanticipated outcomes resulting from national drug shortages.

Fundamental problems with pediatric adaptive dosing of carboplatin using nuclear-medicine-based estimates of renal function.

BACKGROUND: Carboplatin is often adaptively dosed based on glomerular filtration rate (GFR), usually estimated by nuclear medicine tests. At least five pediatric adaptive dosing formulas have been developed. In an effort to standardize dosing in Children's Oncology Group protocols, we explored methodologic variation in GFR estimation and adaptive-dosing formula performance. PROCEDURE: Nuclear medicine GFR data from published series of ≥100 children with cancer were compared. Data from patients for whom body surface area, weight, GFR, and tracer half-life were available were used to compare formulas. RESULTS: Differences in methods used to estimate GFR in children with cancer resulted in highly variable population results, with median GFRs ranging from 96 to 150 mL/min/1.73m2 . The choice of adaptive formula had a major impact on calculated dose. When targeting an area under the curve of 7.9 mg/mL • min, the median difference between the formula yielding the lowest and highest carboplatin dose for individual subjects was 289 (range 96-1 737) mg/m2 . CONCLUSIONS: Wide variation in GFR obtained with nuclear-medicine-based tests in children with cancer primarily results from systematic methodologic errors. Formulas for calculating carboplatin dose produce additional and substantial variation that may place children with cancer at unnecessary risk for excessive toxicity or underdosing. These findings indicate a need for the development of a uniform, validated method for GFR determination in children that should be utilized in all centers. Currently, adaptive dosing of carboplatin based on GFR has serious limitations and in most clinical settings should arguably not be used in place of body-surface-area-based dosing.

A prospective study of a simple algorithm to individually dose high-dose methotrexate for children with leukemia at risk for methotrexate toxicities.

PURPOSE: High-dose methotrexate (HDMTX) is critical to the successful treatment of pediatric acute lymphoblastic leukemia (ALL) but can cause significant toxicities. This study prospectively evaluated the effectiveness of a fixed algorithm which requires no real-time pharmacokinetic modeling and no previous patient exposure to HDMTX, to individualize HDMTX dosing for at-risk patients with the aim of avoiding methotrexate-related toxicities. METHODS: We developed a simple algorithm to individualize HDMTX infusions with 0-2 rate adjustments based on methotrexate levels during the infusion. This was a prospective, open-label, study; eligible patients were identified and referred by their oncologist. RESULTS: Fifty-four evaluable cycles of HDMTX (5 g/m2 over 24 h) were administered to 22 patients. Blood samples were obtained in 21 patients to examine single nucleotide polymorphisms (SNPs) related to methotrexate disposition. Twelve (54.5%) subjects had a history of previous HDMTX toxicities including seven (31.8%) who previously required glucarpidase rescue and seven (31.8%) with an entry glomerular filtration rate < 80 ml/min/1.73 m2. 107/110 (97.2%) of methotrexate levels were drawn properly and 100% of algorithm dosing instructions were performed correctly at the bedside. Thirty-five (64.8%) of all cycles and 24 of 33 (72.7%) cycles that required a dose-adjustment had an end 24-h methotrexate level (Cpss) within our goal range of 65 ± 15 µM with only 3 (5.6%) resulting in Cpss higher than goal. Grade 3/4 toxicities were rare; no patients developed > Grade 1 acute kidney injury. CONCLUSION: This algorithm is a simple, safe and effective method for individualizing HDMTX in pediatric patients with ALL. CLINICALTRIALS. GOV REGISTRY: NCT02076997.

Rapid infusion of rituximab is well tolerated in children with hematologic, oncologic, and rheumatologic disorders.

Traditional administration of rituximab requires careful titration and may involve many hours to minimize the risk of reactions. The objective of this study was to evaluate the safety of rapid infusions of rituximab in a pilot group of children with hematologic, oncologic, and rheumatologic disorders, and to determine the incidence of rate-related infusion reactions. Twenty patients enrolled in the study. All patients tolerated the rapid infusion of rituximab and no patient had an infusion-related reaction. We conclude that rapid infusions of rituximab are well tolerated and safe in our pilot group of patients.

Evaluation of aprepitant for acute chemotherapy-induced nausea and vomiting in children and adolescents with acute lymphoblastic leukemia receiving high-dose methotrexate.

BACKGROUND: Chemotherapy-induced nausea and vomiting (CINV) negatively impacts patients' quality of life. The emetogenicity of high-dose methotrexate in children and adolescents with cancer is incompletely characterized. At our institution, a number of patients with acute lymphoblastic leukemia (ALL) have received aprepitant with courses of high-dose methotrexate after poor CINV control with prior courses. PROCEDURE: We conducted a retrospective cohort analysis on patients with ALL who received methotrexate 5 g/m2 /dose with and without concomitant aprepitant at Texas. Children's Hospital between October 1, 2010 and January 31, 2016. RESULTS: We identified 16 patients who received a total of 69 courses of methotrexate. An enhanced antiemetic regimen containing aprepitant was administered with 42 methotrexate courses and resulted in a 54% reduction in the use of as-needed antiemetics (P = 0.002, 95% CI: 21-89%). There were no statistically significant differences in methotrexate area under the curve values (2,209 µM⋅hr/l ± 151 vs. 2,051 µM⋅hr/l ± 94, P = 0.355) or end-infusion methotrexate concentrations (80.5 µM ± 5.6 vs. 74.7 µM ± 3.2, P = 0.335) in patients receiving a standard versus an enhanced antiemetic regimen. CONCLUSIONS: The addition of aprepitant reduces both CINV and the use of rescue antiemetics. Aprepitant does not appear to affect the pharmacokinetics of methotrexate. Granisetron was prescribed more frequently than ondansetron, but selection of secondary and tertiary agents, if any, was highly variable.

Evaluation of opioid prescribing after rescheduling of hydrocodone-containing products.

PURPOSE: Institutional prescribing trends of hydrocodone-containing products (HCPs) before and after the Drug Enforcement Administration's rescheduling of HCPs were evaluated. METHODS: A retrospective evaluation was performed on 6 oral opioid analgesics on the hospital formulary that were prescribed to patients treated at Texas Children's Hospital and Pavilion for Women for the 6 months before and after the rescheduling of HCPs on October 6, 2014. Patients were eligible for inclusion if they were prescribed any of the following oral agents: HCPs (e.g., hydrocodone with acetaminophen), codeine-containing products (e.g., codeine, codeine with acetaminophen), morphine, hydromorphone, oxycodone-containing products (e.g., oxycodone, oxycodone with acetaminophen), and tramadol. RESULTS: During the 12-month study period, a total of 38,928 inpatient orders and outpatient prescriptions were processed for the studied agents in both locations; the majority were orders for inpatients. An overall reduction in the total number of opioid prescriptions was observed after the rescheduling of HCPs. Substantial increases in the proportional use of codeine were observed in all 4 settings after HCP rescheduling. Data for each of the agents revealed a shift in prescribing patterns centered along the HCP rescheduling date of October 6, 2014, and revealed a decrease in HCP use across all areas with an accompanying increase in codeine-containing products, oxycodone-containing products, and tramadol. CONCLUSION: The rescheduling of HCPs resulted in a reduction in HCP prescriptions but was accompanied by increases in the use of codeine-containing products and tramadol in all settings.
