Busulfan with 400 centigray of total body irradiation and higher dose fludarabine: An alternative regimen for hematopoietic stem cell transplantation in pediatric acute lymphoblastic leukemia.

BACKGROUND: Hematopoietic stem cell transplantation can be curative for children with difficult-to-treat leukemia. The conditioning regimen utilized is known to influence outcomes. We report outcomes of the conditioning regimen used at the Alberta Children's Hospital, consisting of busulfan (with pharmacokinetic target of 3750 µmol*min/L/day ±10%) for 4 days, higher dose (250 mg/m2 ) fludarabine and 400 centigray (cGy) of total body irradiation. PROCEDURE: This retrospective study involved children receiving transplant for acute lymphoblastic leukemia (ALL). It compared children who fell within the target range for busulfan with those who were either not measured or were measured and fell outside this range. All other treatment factors were identical. RESULTS: Twenty-nine children (17 within target) were evaluated. All subjects engrafted neutrophils with a median [interquartile range] time of 14 days [8-30 days]. The cumulative incidence of acute graft-versus-host disease was 44.8% [95% confidence interval, CI: 35.6%-54.0%], while chronic graft-versus-host disease was noted in 16.0% [95% CI: 8.7%-23.3%]. At 2 years, the overall survival was 78.1% [95% CI: 70.8%-86.4%] and event-free survival was 74.7% [95% CI: 66.4%-83.0%]. Cumulative incidence of relapse was 11.3% [95% CI: 5.1%-17.5%]. There were no statistically significant differences in between the group that received targeted busulfan compared with the untargeted group. CONCLUSION: Our conditioning regiment for children with ALL resulted in outcomes comparable to standard treatment with acceptable toxicities and significant reduction in radiation dose. Targeting busulfan dose in this cohort did not result in improved outcomes.

Neuropsychological, behavioral, and quality-of-life outcomes in children and adolescents with sickle cell disease treated with nonmyeloablative matched sibling donor hematopoietic cell transplantation: A case series.

BACKGROUND/OBJECTIVES: Despite advances in the treatment of sickle cell disease (SCD), cerebrovascular and cognitive insults can have lifelong consequences. Hematopoietic cell transplantation (HCT) is an established curative therapy, and recent studies have demonstrated efficacy with reduced toxicity nonmyeloablative (NMA) regimens, but little is known about neuropsychological outcomes. The objective of this study was to describe neuropsychological, behavioral, and quality-of-life outcomes with medical correlates in children with SCD who received an NMA matched sibling donor (MSD) HCT. DESIGN/METHODS: Retrospective cohort analysis of nine recipients with hemoglobin SS SCD who underwent MSD HCT using the National Institutes of Health (NIH) NMA protocol. RESULTS: Mean full-scale intellectual functioning (FSIQ) was average pre-HCT (FSIQ = 92.1, SD 9.0; n = 8) and 2 years post-HCT (mean FSIQ = 96.6; SD 11.1; N = 9). Neuropsychological functioning was largely average across all cognitive domains, and no pre/post-HCT differences were found to be statistically significant given the small sample size. However, effect sizes revealed moderate improvements in processing speed (Cohen's d = .72) and verbal memory (Cohen's d = .60) post-HCT, and declines in measures of attention (Cohen's d = -.54) and fine motor speed and dexterity (Cohen's d = -.94). Parents endorsed better quality of life (Cohen's d = .91), less impact of SCD on their family, and less worry about their child's future (Cohen's d = 1.44). CONCLUSION: Neuropsychological functioning in a sample of children and adolescents treated uniformly with NMA MSD HCT remained stable or improved in most cognitive domains, and improvements in quality of life and family functioning were observed.

ADaPTS "(AD)olescents (P)ath through (T)ransplant (S)ickle cell disease".

BACKGROUND: Sickle cell disease is an inherited chronic hematological disorder with an average lifespan of fifty years. The human cost of sickle cell disease includes missed school days, occupational opportunities, social isolation, stigmatization, and psychological sequelae. Hematopoietic cell transplantation (HCT) is the only curative therapy available but comes with potential morbidity and mortality. Our study explores how quality of life (QoL) is affected from the perspective of an adolescent who has undergone a nonmyeloablative matched sibling donor HCT. METHODS: We employed multiple case study methodology with purposeful sampling by selecting information-rich cases. DATA SOURCES: 1) QoL inventories 2) patient interviews 3) parent interview 4) vital support interview 5) medical record analysis. DATA ANALYSIS: Intra-case analysis by assembling evidence within a single case and then analyzing the differences within cases to create a rich case description. Next, a time series analysis was completed to track changes in patients' QoL. We used multiple sources of data to compose a timeline and changes across time. Then, we employed pattern matching as an analytical technique allowing for examination of patterns across cases. Finally, we used cross case synthesis to review results of each case. RESULTS: Quality of life was reported across the physical, social and psychological domains for 5 participants. All had sickle cell HgSS genotype, 80% were male and 80% were born outside of Canada. Physical domain: pre-transplant, 100% of patients experienced pain, and the majority suffered from fatigue, insomnia, and fevers resulting in hospitalizations. Afterwards, participants reported improved physical wellbeing. Social domain: pre-transplant, QoL was poor characterized by stigma, social isolation, and parental absenteeism. Post-HSCT adolescents gained social acceptance in areas that had stigmatized and excluded them. They were able to participate freely in activities with peers and their social life vastly improved. Psychological pre-transplant life experiences were overshadowed by psychological stress. The majority commented that their future was bleak and may lead to premature death. Afterwards adolescents described a crisis free life with positive psychological outcomes. CONCLUSIONS: Adolescents with sickle cell disease who undertook HCT demonstrated improved QoL one year post transplant with regard to physical, social and psychological well-being.

A population-based analysis of the presentation and outcomes of pediatric patients with osteosarcoma in Canada: a report from CYP-C.

BACKGROUND: Frequently occurring in adolescents, osteosarcoma is the most common primary malignant bone disease, with a reported 15% of patients who present with metastasis. With advances in imaging and improvements in surgical care, an updated analysis is warranted on the outcomes of pediatric patients with osteosarcoma. METHODS: We completed a retrospective review of pediatric patients who presented with osteosarcoma between 2001 and 2017, using The Cancer in Young People in Canada (CYP-C) national database. Data on 304 patients aged younger than 15 years were analyzed. RESULTS: The proportion of patients who presented with metastasis was 23.0%. The overall 5-year survival (OS) for patients who presented with metastasis was 37.4%. Overall survival and event-free survival (EFS) were lower in these patients than in patients with localized disease (hazard ratio [HR] 4.3, p < 0.0001 and HR 3.1, p < 0.0001). For patients who presented with metastatic disease, the OS for those undergoing an operative intervention was 44.1% compared with 17.6% for those who did not undergo resection (p < 0.0001). CONCLUSION: The proportion of patients who presented with metastatic osteosarcoma in our population is higher than previously reported. Overall outcomes of patients with metastatic disease have not changed. Our data reaffirm a role for surgical resection in patients with metastasis with a need to explore new treatment strategies to improve the overall prognosis of these patients.

Fludarabine, Campath, and Low-Dose Cyclophosphamide (FCClow) with or without TBI Conditioning Results in Excellent Transplant Outcomes in Children with Severe Aplastic Anemia.

Various reduced-intensity conditioning regimens are in use for allogeneic hematopoietic cell transplant (HSCT) in patients with idiopathic severe aplastic anemia (SAA). We describe the use of fludarabine, Campath, and low-dose cyclophosphamide (FCClow) conditioning in 15 children undergoing related or unrelated donor transplants. Total body irradiation (TBI) of 2 Gy was added for unrelated donor HSCT. At a median follow-up of 2.3 years, the failure-free survival was 100%, with low rates of infection and toxicity. There was no occurrence of grade III to IV acute graft-versus-host disease (GVHD). All patients had full donor myeloid chimerism post-HSCT, even with mixed chimerism in the T cell lineage. The absence of chronic GVHD and long-term stable mixed donor T cell chimerism confirms immune tolerance following FCClow (± TBI) conditioned transplantation in children with SAA.

Regional differences in access to hematopoietic stem cell transplantation among pediatric patients with acute myeloid leukemia.

INTRODUCTION: Indications for hematopoietic stem cell transplantation (HSCT) in pediatric acute myeloid leukemia (AML) are primarily dependent on risk stratification at diagnosis and relapse status. We sought to determine whether access to HSCT is influenced by regional and socioeconomic factors. METHODS: Children with newly diagnosed AML aged < 15 years between 2001 and 2015 were identified using the Cancer in Young People in Canada national population-based registry. Factors potentially associated with the receipt of HSCT were studied using univariate and multivariable logistic regression models. RESULTS: Overall, 568 children with newly diagnosed AML were included and 262 (46%) received HSCT. A greater proportion of patients, 103/157 (65.6%), underwent HSCT after first or subsequent relapse compared to 159/411 (38.7%) patients who underwent transplant before relapse. Among patients for whom HSCT would be considered before relapse, factors associated with higher odds of HSCT in a multivariable analysis were: poor versus good-risk cytogenetics (Odds ratio [OR]: 30.0, 95% confidence interval [CI]: 7.7-117.0), diagnosis during 2012-2015 versus 2001-2006 (OR: 3.2, 95% CI: 1.6-6.3), diagnosis in eastern Canada versus central Canada (OR: 3.7, 95% CI: 1.9-7.3), and age 10-14 years versus age < 1 year (OR: 5.4, 95% CI: 2.3-12.8). Among patients for whom HSCT would be considered after first relapse, higher odds of HSCT was associated with diagnosis at a HSCT center (OR: 2.1, 95% CI: 1.1-4.1). CONCLUSION: Patients diagnosed at a HSCT performing center and patients from eastern Canada had higher odds of receiving HSCT. This may suggest preferential access to HSCT for certain patients.

Nonmyeloablative Matched Sibling Donor Hematopoietic Cell Transplantation in Children and Adolescents with Sickle Cell Disease.

Sickle cell disease is a potentially debilitating hemoglobinopathy associated with early mortality. The only established curative therapy is hematopoietic cell transplantation (HCT) with a matched sibling donor. The National Institutes of Health nonmyeloablative regimen of alemtuzumab/300 cGy total body irradiation and prolonged sirolimus exposure for graft-versus-host disease (GVHD) prophylaxis was administered to 16 children and adolescents. Infused products were unmanipulated granulocyte colony stimulating factor mobilized peripheral blood stem cells. All patients achieved mixed donor-recipient engraftment with no cases of secondary graft failure to date. Two patients have donor myeloid chimerism in the range of 30% to 40%. No sickling crises post-HCT have been observed. Event-free and overall survival rates are 100% with median follow-up of 19.5 months. No cases of GVHD have been observed. Sirolimus weaning was possible in all but one eligible patient to date. Ongoing follow-up and a larger prospective clinical trial are required to determine the long-term safety and efficacy of this regimen in children.

Access to Hematopoietic Stem Cell Transplantation among Pediatric Patients with Acute Lymphoblastic Leukemia: A Population-Based Analysis.

Access to hematopoietic stem cell transplantation (HSCT) in pediatric acute lymphoblastic leukemia (ALL) primarily depends on disease-related factors but may be influenced by social and economic determinants. We included all children aged < 15 years with newly diagnosed ALL in Canada between 2001 and 2018 using the Cancer in Young People in Canada national registry. We examined factors potentially associated with the likelihood of receiving HSCT using univariate and multivariable logistic regression models. A total of 3992 patients with newly diagnosed ALL were included. Three hundred twenty-five (8.1%) received an HSCT and formed the transplant cohort. In multivariable analysis factors independently associated with an increased odds of receiving HSCT were male sex (odds ratio [OR], 1.42; 95% confidence interval [CI], 1.05 to 1.93), initial WBC ≥ 50,000 × 109/L (OR, 1.58; 95% CI, 1.09 to 2.28), mixed phenotype acute leukemia relative to B-precursor ALL (OR, 34.32; 95% CI, 16.64 to 70.79), T cell relative to B-precursor ALL (OR, 1.77; 95% CI, 1.07 to 2.91), unfavorable relative to standard cytogenetics (OR, 3.96; 95% CI, 2.56 to 6.12), and relapse before HSCT (OR, 32.77; 95%, 23.89 to 44.96). No association was found between race, neighborhood income quintile or region at diagnosis, and receipt of HSCT. Diagnosis at an HSCT treating center (OR, 1.51; 95% CI, 1.09 to 2.09) and residential distance from the ALL treating center (OR, 1.84 for ≥300 km compared with <100 km; 95% CI, 1.17 to 2.91) were associated with higher odds of receiving HSCT. In a publically funded healthcare system, children with ALL had equitable access to HSCT, which was largely governed by biologic disease-related factors. Patients diagnosed at an HSCT performing center and patients who live farthest away from their treatment center had higher odds of receiving HSCT, although the effect was small, possibly suggesting preferential referral to HSCT for some patients.

Targeted Polo-like Kinase Inhibition Combined With Aurora Kinase Inhibition in Pediatric Acute Leukemia Cells.

BACKGROUND: Recent studies have shown that cell cycle events are tightly controlled by complex and shared activities of a select group of kinases. Among these, polo-like kinases (Plks) are regulatory mitotic proteins that are overexpressed in several types of cancer and are associated with poor prognosis. MATERIALS AND METHODS: We have evaluated, in preclinical in vitro studies, the activity of a panel of Plk inhibitors against cell lines derived from refractory pediatric leukemia, as well as primary leukemia cells, in culture. Through in vitro growth inhibition studies, Western blot analysis for the expression and activation of key regulators of cell growth and survival and gene silencing studies, we specifically examined the ability of these agents to induce cytotoxicity through the activation of apoptosis and their capacity to interact and modulate the expression and phosphorylation of Aurora kinases. RESULTS: Our findings show that the various Plk-1 inhibitors in development show potential utility for the treatment of pediatric leukemia and exhibit a wide range of phosphorylation and target modulatory capabilities. Finally, we provide evidence for a complex interregulatory relationship between Plk-1 and Aurora kinases enabling the identification of synergy and biologic correlates of drug combinations targeting the 2 distinct enzyme systems. DISCUSSION: This information provide the rationale for the evaluation of Plk-1 as an effective target for therapeutics in refractory pediatric leukemia and indicate compensatory activities between Plk-1 and Aurora kinases, providing insight into some of the complex mechanisms involved in the process of cell division.

Predictive factors for successful peripheral blood stem cell mobilization and collection in children.

Factors affecting the success of peripheral blood stem cell collection (SCC) in children are not well characterized. We reviewed 218 stem cell collections among 199 pediatric donors, of which 35 were from healthy sibling donors and 164 were for autologous collections. Successful SCC, defined as a CD34+ cell count of ≥2 × 106 /kg of recipient weight per intended transplant, occurred in 188 of 199 donors (94%). Ideal SCC defined ≥5 × 106 CD34+ cells/kg of recipient per intended transplant, occurred in 147 (74%) patients. Failure of collection occurred in 11 (6%) patients and was significantly associated with an autologous collection for a brain tumor diagnosis (P = .003) and a pre-apheresis peripheral blood (PB) CD34+ count <20 × 106 cells/L (P = .002). Ideal SCC was significantly associated with age < 10 years (P = .01) and pre-apheresis PB-CD34+ count ≥20 × 106 cells/L (P < .0001). Factors associated with failure of SCC may be identified in advance of the collection procedure allowing appropriate counselling of patients as well as anticipatory guidance for multiple collections or justify the preemptive use of stem cell mobilizing agents.

Enrollment on clinical trials does not improve survival for children with acute myeloid leukemia: A population-based study.

BACKGROUND: It is questionable whether enrollment on clinical trials offers any survival advantage at the population level over standard-of-care treatment. The objectives of this study were to describe the impact of trial enrollment on event-free survival and overall survival in pediatric acute myeloid leukemia (AML) using the Cancer in Young People in Canada (CYP-C) database. METHODS: Children were included if they had had AML newly diagnosed between ages birth and 14 years from 2001 to 2012. CYP-C is a national pediatric cancer population-based database that includes all cases of pediatric cancer diagnosed and treated at 1 of the 17 tertiary pediatric oncology centers in Canada. Univariate and Cox proportional hazards models were used to evaluate the impact of initial trial enrollment on survival. RESULTS: In total, 397 eligible children with AML were included in the analysis, of whom 94 (23.7%) were enrolled on a clinical trial at initial diagnosis. The most common reason for non-enrollment was that no trial was available. The event-free survival rate at 5 years was 57.8% ± 5.2% for those enrolled versus 54.8% ± 2.9% for those not enrolled (P = .75). The overall survival rate at 5 years was 70.1% ± 4.9% for those enrolled versus 66.3% ± 2.8% for those not enrolled (P = .58). Enrollment on a trial was not associated with improved event-free or overall survival in multiple regression analyses. CONCLUSIONS: Enrollment on a clinical trial was not associated with improved survival for children with AML in a population-based cohort. Rationale for trial enrollment should not include the likelihood of benefit compared with non-enrollment.

Enrolling children with acute lymphoblastic leukaemia on a clinical trial improves event-free survival: a population-based study.

BACKGROUND: The objectives of this study were to describe the impact of trial enrollment at diagnosis on event-free and overall survival in paediatric acute lymphoblastic leukaemic (ALL) using a population-based approach. METHODS: We conducted a retrospective cohort study that included children newly diagnosed with ALL between 1 and 14 years of age. The data source was the Cancer in Young People in Canada (CYP-C) national paediatric cancer population-based database. We conducted univariate and multiple Cox proportional hazards models. RESULTS: There were 2569 children with ALL; 1408 (54.8%) were enrolled on a clinical trial at initial diagnosis. Event-free survival at 5 years was 89.8%±0.9 vs 84.1%±1.2. (P<0.0001) for those enrolled and not enrolled on a clinical trial, respectively. Overall survival at 5 years was higher for those enrolled (94.1%±0.7) vs not enrolled (90.5%±1.0; P=0.001). In a model that adjusted for demographic, leukaemic and socioeconomic factors, enrollment on trials was significantly associated with better event-free survival (hazard ratio (HR) 0.67, 95% confidence interval (CI) 0.47-0.95; P=0.023), but not overall survival (HR 0.69, 95% CI 0.44-1.08; P=0.102). CONCLUSIONS: Event-free survival was significantly better in children with ALL enrolled on a clinical trial. Future research should identify barriers to clinical trial enrollment for children with ALL.

Evaluation of mobile phone applications to support medication adherence and symptom management in oncology patients.

Mobile phone applications (apps), may support pediatric oncology patients with medication and disease management. A scoping review of the literature, a search of the iTunes App and Google Play Stores, was conducted to identify medication and symptom management apps for adult and pediatric oncology patients. Pooled results yielded 28 apps which were assessed for quality using the Mobile Application Rating Scale, with mean overall scores ranging from 2.8 to 4.3. Most apps received low scores in the Engagement domain. Our study assessed the quality of available mobile oncology apps and identified areas for improvement in design and function.

Most children with cancer are not enrolled on a clinical trial in Canada: a population-based study.

BACKGROUND: Primary objective was to describe the proportion of children newly diagnosed with cancer enrolled on a therapeutic clinical trial. Secondary objectives were to describe reasons for non-enrollment and factors associated with enrollment on trials. METHODS: In this retrospective cohort study, we included children newly diagnosed with cancer between 0 and 14 years of age and diagnosed from 2001 to 2012. We used data from the Cancer in Young People in Canada (CYP-C) national pediatric cancer population-based database. CYP-C captures all cases of pediatric cancer (0-14 years) diagnosed and treated at one of the 17 tertiary pediatric oncology centers in Canada. Non-enrollment was evaluated using univariate and multiple logistic regression analysis. RESULTS: There were 9204 children with cancer included, of whom 2533 (27.5%) were enrolled on a clinical trial. The most common reasons cited for non-enrollment were lack of an available trial (52.2%) and physician choice (11.2%). In multiple regression, Asian and Arab/west Asian race were associated with lower enrollment (P = 0.006 and P = 0.032 respectively). All cancer diagnoses were more likely to be enrolled compared to astrocytoma and children with acute lymphoblastic leukemia had an almost 18-fold increased odds of enrollment compared to astrocytoma (P < 0.0001). Greater distance from the tertiary care center was independently associated with non-enrollment (P < 0.0001). CONCLUSIONS: In Canada, 27.5% of children with cancer are enrolled onto therapeutic clinical trials and lack of an available trial is the most common reason contributing to non-enrollment. Future research should better understand reasons for lack of trial availability and physician preferences to not offer trials.

The Evolution of Metastatic Colorectal Cancer Clinical Trials: Application of the ASCO Framework for Assessing Value.

Background: Phase III trials in metastatic colorectal cancer (mCRC) have collectively led to progressive advancements in patient outcomes over the past decades. This study characterizes the evolution of mCRC phase III trials through assessing the value of cancer therapy, as measured by the ASCO Value Framework. Methods: Phase III trial results of systemic therapy for mCRC published between 1980 and 2015 were identified, and their outcome, statistical significance, journal impact factor, and citation by the 2016 NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for CRC were recorded. For each trial, the net health benefit (NHB) score was calculated using the June 2015 (original) and May 2016 (revised) ASCO Value Framework: Advanced Disease. Results: There were 114 mCRC phase III trials eligible for calculation of the NHB score. Using the revised framework, the median NHB score was 4.6 (range, -30 to 43.5); 12% of trials received bonus points. Trials with statistically significant results had higher NHB scores compared with nonsignificant trials (median NHB score, 21.6 vs 2.9; P<.0001). Clinical trials cited in the NCCN Guidelines had higher NHB scores than those not cited (median score, 8.0 vs 0.3; P=.02). In multivariate linear regression analysis, the only significant predictor of high NHB score was statistically significant studies. Conclusions: The median NHB score for mCRC phase III trials was 4.6. Higher NHB scores are associated with statistically significant studies and are cited in the NCCN Guidelines, a surrogate for practice-changing trials. The 2016 ASCO Value Framework may not fully capture the benefits on an individual patient level.

Adult patient perspectives on clinical trial result reporting: A survey of cancer patients.

BACKGROUND: The provision of study results to research participants is supported by pediatric and adult literature. This study assessed adult cancer patient preferences surrounding aggregate result disclosure to study participants. METHODS: A 46-item questionnaire was given to 250 adult cancer patients who had participated in oncology trials at a single center. Respondents answered questions surrounding their preferences for timing, content, and modality of communication for dissemination of study results. RESULTS: Questionnaire completion rate was 76% (189/250). Most patients (92%) strongly felt a right to know study results. Patients preferred result dissemination via letter for trials with positive outcomes, but preferred in-person clinic visits for negative outcomes. Despite this, a majority of participants (59%) found letters acceptable to inform participants of negative results. Only a minority (36%) of the participants found Internet-based disclosure acceptable for negative trial results. Unfortunately, very few patients (8%) recalled having received the results for a study they participated in, and of these patients, less than half fully understood the results they were given. CONCLUSION: Most clinical trial participants feel they have a right to study result disclosure, regardless of trial outcome. In-person visits are preferred for negative results, but more feasible alternatives such as letters were still acceptable for the majority of participants. However, Internet-based disclosure was not acceptable to most participants in oncology trials. Time and cost allocations for result disclosure should be considered during grant and ethics board applications, and clear guidelines are required to help researchers share the results with patients.

Comparison of oncology drug approval between Health Canada and the US Food and Drug Administration.

BACKGROUND: The drug approval timeline is a lengthy process that often varies between countries. The objective of this study was to delineate the Canadian drug approval timeline for oncology drugs and to compare the time to drug approval between Health Canada (HC) and the US Food and Drug Administration (FDA). METHODS: In total, 54 antineoplastic drugs that were approved by the FDA between 1989 and 2012 were reviewed. For each drug, the following milestones were determined: the dates of submission and approval for both the FDA and HC and the dates of availability on provincial drug formularies in Canadian provinces and territories. The time intervals between the aforementioned milestones were calculated. RESULTS: Of 54 FDA-approved drugs, 49 drugs were approved by HC at the time of the current study. The median time from submission to approval was 9 months (interquartile range [IQR], 6-14.5 months) for the FDA and 12 months (IQR, 10-21.1 months) for HC (P < .0006). The time from HC approval to the placement of a drug on a provincial drug formulary was a median of 16.7 months (IQR, 5.9-27.2 months), and there was no interprovincial variability among the 5 Canadian provinces that were analyzed (P = .5). CONCLUSIONS: The time from HC submission to HC approval takes 3 months longer than the same time interval for the FDA. To the authors' knowledge, this is the first documentation of the time required to bring an oncology drug from HC submission to placement on a provincial drug formulary.

A Randomized Controlled Trial of Nonfasting vs Fasting Before Interventional Coronary Procedures: The TONIC Trial.

BACKGROUND: Fasting before coronary procedures is currently recommended to reduce complications despite the lack of scientific evidence. OBJECTIVES: The TONIC (Comparison Between Fasting and No Fasting Before Interventional Coronary Intervention on the Occurrence of Adverse Events) noninferiority trial investigated the safety and comfort of a nonfasting strategy (ad libitum food and drinks) vs traditional fasting (>6 hours for solid food and liquids) before coronary procedures. METHODS: In this monocentric, prospective, single-blind randomized controlled trial, 739 patients undergoing coronary procedures were included and randomized to a fasting or a nonfasting strategy. Emergency procedures were excluded. The primary endpoint was a composite of vasovagal reaction, hypoglycemia (defined by blood sugar ≤0.7 g/L), and isolated nausea and/or vomiting. Noninferiority margin was 4%. Secondary endpoints were contrast-induced nephropathy and patients' satisfaction. RESULTS: Among the 739 procedures (697 elective and 42 semiurgent), 517 angiographies, and 222 angioplasties (including complex and high-risk procedures) were performed. The primary endpoint occurred in 30 of 365 nonfasting patients (8.2%) vs 37 of 374 fasting patients (9.9%), demonstrating noninferiority (absolute between-group difference, -1.7%; 1-sided 95% CI upper limit: 1.8%). No food-related adverse event occurred, and contrast-related acute kidney injuries were similar between groups. Overall, procedure satisfaction and perceived pain were similar in both groups, but nonfasting patients reported less hunger and thirst (P < 0.01). In case of redo coronary procedures, most patients (79%) would choose a nonfasting strategy. CONCLUSIONS: The TONIC randomized trial demonstrates the noninferiority of a nonfasting strategy to the usual fasting strategy for coronary procedures regarding safety, while improving patients' comfort.
