RESUMEN

Importance: The clinical effects of risankizumab (a monoclonal antibody that selectively targets the p19 subunit of IL-23) for the treatment of ulcerative colitis are unknown. Objective: To evaluate the efficacy and safety of risankizumab when administered as an induction and a maintenance therapy for patients with ulcerative colitis. Design, Setting, and Participants: Two phase 3 randomized clinical trials were conducted. The induction trial was conducted at 261 clinical centers (in 41 countries) and enrolled 977 patients from November 5, 2020, to August 4, 2022 (final follow-up on May 16, 2023). The maintenance trial was conducted at 238 clinical centers (in 37 countries) and enrolled 754 patients from August 28, 2018, to March 30, 2022 (final follow-up on April 11, 2023). Eligible patients had moderately to severely active ulcerative colitis; a history of intolerance or inadequate response to 1 or more conventional therapies, advanced therapies, or both types of therapies; and no prior exposure to risankizumab. Interventions: For the induction trial, patients were randomized 2:1 to receive 1200 mg of risankizumab or placebo administered intravenously at weeks 0, 4, and 8. For the maintenance trial, patients with a clinical response (determined using the adapted Mayo score) after intravenous treatment with risankizumab were randomized 1:1:1 to receive subcutaneous treatment with 180 mg or 360 mg of risankizumab or placebo (no longer receiving risankizumab) every 8 weeks for 52 weeks. Main Outcomes and Measures: The primary outcome was clinical remission (stool frequency score ≤1 and not greater than baseline, rectal bleeding score of 0, and endoscopic subscore ≤1 without friability) at week 12 for the induction trial and at week 52 for the maintenance trial. Results: Among the 975 patients analyzed in the induction trial (aged 42.1 [SD, 13.8] years; 586/973 [60.1%] were male; and 677 [69.6%] were White), the clinical remission rates at week 12 were 132/650 (20.3%) for 1200 mg of risankizumab and 20/325 (6.2%) for placebo (adjusted between-group difference, 14.0% [95% CI, 10.0%-18.0%], P < .001). Among the 548 patients analyzed in the maintenance trial (aged 40.9 [SD, 14.0] years; 313 [57.1%] were male; and 407 [74.3%] were White), the clinical remission rates at week 52 were 72/179 (40.2%) for 180 mg of risankizumab, 70/186 (37.6%) for 360 mg of risankizumab, and 46/183 (25.1%) for placebo (adjusted between-group difference for 180 mg of risankizumab vs placebo, 16.3% [97.5% CI, 6.1%-26.6%], P < .001; adjusted between-group difference for 360 mg of risankizumab vs placebo, 14.2% [97.5% CI, 4.0%-24.5%], P = .002). No new safety risks were detected in the treatment groups. Conclusion and Relevance: Compared with placebo, risankizumab improved clinical remission rates in an induction trial and in a maintenance trial for patients with moderately to severely active ulcerative colitis. Further study is needed to identify benefits beyond the 52-week follow-up. Trial Registration: ClinicalTrials.gov Identifiers: NCT03398148 and NCT03398135.

RESUMEN

BACKGROUND: Previous studies have reported that rituximab (RTX) therapy might be beneficial in reducing relapse rates in patients with IgG4-related disease (IgG4-RD). Therefore, we aimed to systematically assess the efficacy and safety of RTX induction treatment and the effect of RTX maintenance in patients with IgG4-RD. METHODS: The protocol was registered in the PROSPERO (CRD42023427352). PubMed, Embase, the Cochrane database, Scopus, and the Web of Science were interrogated to identify studies that evaluated the impact of RTX on prognosis in IgG4-RD. We explored the impact of various subgroups of factors on relapse outcomes and focused on the possible role of maintenance therapy in reducing relapse rates. The pooled incidence of adverse events of RTX therapy and the influencing factors have also been evaluated. RESULTS: Eighteen studies comprising 374 patients (mean age 56.0 ± 8.7 years; male 73.7 %) with a mean follow-up duration of 23.4 ± 16.3 months were included. The pooled estimate of the response rate, complete remission rate, overall relapse rate, adverse event rate, and serious adverse event rate of RTX induction therapy were 97.3 % (95 % CI, 94.7 %-99.1 %), 55.8 % (95 % CI, 39.6 %-71.3 %), 16.9 % (95 % CI, 8.7 %-27.1 %), 31.6 % (95 % CI, 16.7 %-48.9 %) and 3.9 % (95 % CI, 0.8 %-8.9 %), respectively. In subgroup analysis, the pooled relapse rate was significantly lower in studies with maintenance than without maintenance (2.8% vs 21.5 %, p < 0.01). Pooled Kaplan-Meier relapse curves also demonstrated that RTX maintenance therapy provided a better prognosis. CONCLUSIONS: RTX induction therapy appears to have satisfactory efficacy in the induction of remission in IgG4-RD. In addition, prophylactic RTX maintenance therapy after induction may be beneficial in preventing relapse of IgG4-RD.

RESUMEN

Consolidation therapy consists of short-term therapy after stem cell transplant in multiple myeloma. Key consolidation trials have shown mixed results on whether consolidation should be included after transplant, leading to varied clinical practice. Maintenance therapy consists of long-term, typically fixed-duration or indefinite, therapy. Standard-risk patients typically receive single-agent therapy, whereas high-risk may benefit from doublet therapy and beyond. Adverse events and quality of life concerns should be considered, as optimal duration of maintenance therapy continues to be studied.

RESUMEN

BACKGROUND: Mirikizumab, a p19-directed antibody against interleukin-23, showed efficacy in the treatment of ulcerative colitis in a phase 2 trial. METHODS: We conducted two phase 3, randomized, double-blind, placebo-controlled trials of mirikizumab in adults with moderately to severely active ulcerative colitis. In the induction trial, patients were randomly assigned in a 3:1 ratio to receive mirikizumab (300 mg) or placebo, administered intravenously, every 4 weeks for 12 weeks. In the maintenance trial, patients with a response to mirikizumab induction therapy were randomly assigned in a 2:1 ratio to receive mirikizumab (200 mg) or placebo, administered subcutaneously, every 4 weeks for 40 weeks. The primary end points were clinical remission at week 12 in the induction trial and at week 40 (at 52 weeks overall) in the maintenance trial. Major secondary end points included clinical response, endoscopic remission, and improvement in bowel-movement urgency. Patients who did not have a response in the induction trial were allowed to receive open-label mirikizumab during the first 12 weeks of the maintenance trial as extended induction. Safety was also assessed. RESULTS: A total of 1281 patients underwent randomization in the induction trial, and 544 patients with a response to mirikizumab underwent randomization again in the maintenance trial. Significantly higher percentages of patients in the mirikizumab group than in the placebo group had clinical remission at week 12 of the induction trial (24.2% vs. 13.3%, P<0.001) and at week 40 of the maintenance trial (49.9% vs. 25.1%, P<0.001). The criteria for all the major secondary end points were met in both trials. Adverse events of nasopharyngitis and arthralgia were reported more frequently with mirikizumab than with placebo. Among the 1217 patients treated with mirikizumab during the controlled and uncontrolled periods (including the open-label extension and maintenance periods) in the two trials, 15 had an opportunistic infection (including 6 with herpes zoster infection) and 8 had cancer (including 3 with colorectal cancer). Among the patients who received placebo in the induction trial, 1 had herpes zoster infection and none had cancer. CONCLUSIONS: Mirikizumab was more effective than placebo in inducing and maintaining clinical remission in patients with moderately to severely active ulcerative colitis. Opportunistic infection or cancer occurred in a small number of patients treated with mirikizumab.

RESUMEN

BACKGROUND: Upadacitinib, an oral selective Janus kinase (JAK) inhibitor, is under investigation for the treatment of Crohn's disease. METHODS: In two phase 3 induction trials (U-EXCEL and U-EXCEED), we randomly assigned patients with moderate-to-severe Crohn's disease to receive 45 mg of upadacitinib or placebo (2:1 ratio) once daily for 12 weeks. Patients who had a clinical response to upadacitinib induction therapy were randomly assigned in the U-ENDURE maintenance trial to receive 15 mg of upadacitinib, 30 mg of upadacitinib, or placebo (1:1:1 ratio) once daily for 52 weeks. The primary end points for induction (week 12) and maintenance (week 52) were clinical remission (defined as a Crohn's Disease Activity Index score of <150 [range, 0 to 600, with higher scores indicating more severe disease activity]) and endoscopic response (defined as a decrease in the Simple Endoscopic Score for Crohn's Disease [SES-CD; range, 0 to 56, with higher scores indicating more severe disease] of >50% from baseline of the induction trial [or for patients with an SES-CD of 4 at baseline, a decrease of ≥2 points from baseline]). RESULTS: A total of 526 patients underwent randomization in U-EXCEL, 495 in U-EXCEED, and 502 in U-ENDURE. A significantly higher percentage of patients who received 45-mg upadacitinib than those who received placebo had clinical remission (in U-EXCEL, 49.5% vs. 29.1%; in U-EXCEED, 38.9% vs. 21.1%) and an endoscopic response (in U-EXCEL, 45.5% vs. 13.1%; in U-EXCEED, 34.6% vs. 3.5%) (P<0.001 for all comparisons). At week 52 in U-ENDURE, a higher percentage of patients had clinical remission with 15-mg upadacitinib (37.3%) or 30-mg upadacitinib (47.6%) than with placebo (15.1%), and a higher percentage had an endoscopic response with 15-mg upadacitinib (27.6%) or 30-mg upadacitinib (40.1%) than with placebo (7.3%) (P<0.001 for all comparisons). Herpes zoster infections occurred more frequently in the 45-mg and 30-mg upadacitinib groups than in the respective placebo groups, and hepatic disorders and neutropenia were more frequent in the 30-mg upadacitinib group than in the other maintenance groups. Gastrointestinal perforations developed in 4 patients who received 45-mg upadacitinib and in 1 patient each who received 30-mg or 15-mg upadacitinib. CONCLUSIONS: Upadacitinib induction and maintenance treatment was superior to placebo in patients with moderate-to-severe Crohn's disease.

RESUMEN

INTRODUCTION: Relapsed and refractory B-cell acute lymphoblastic leukaemia (R/R-B-ALL) is linked to a significant relapse rate after allogeneic haematopoietic cell transplantation (allo-HCT) in children, adolescents and young adults (CAYA). No standard treatment has been established to prevent relapse after allo-HCT for R/R-B-ALL, which is an unmet medical need. The administration of blinatumomab after allo-HCT is expected to enhance the antileukaemic effect on residual CD19-positive blasts by donor-derived CD3-positive T-cells. METHODS AND ANALYSIS: The goal of this multicentre, open-label, uncontrolled, phase I-II clinical trial is to assess the safety and effectiveness of post-transplant maintenance therapy with blinatumomab for CAYA patients (25 years old or younger) with CD19-positive R/R-B-ALL who have received allo-HCT beyond first complete remission (CR) and have CR with haematological recovery between 30 and 100 days after allo-HCT. Eighty-five paediatric institutions in Japan are participating in this study. Forty-one patients will enrol within 2.25-year enrolment period and follow-up period is 1 year. The primary endpoints are the treatment completion rate for phase I study and the 1-year graft-versus-host disease-free/relapse-free survival rate for phase II study, respectively. ETHICS AND DISSEMINATION: This research was approved by the Central Review Board at National Hospital Organization Nagoya Medical Center (Nagoya, Japan) on 21 January 2022 and was registered at the Japan Registry of Clinical Trials (jRCT) on 3 March 2022. Written informed consent is obtained from all patients and/or their guardians. The results of this study will be disseminated through peer-reviewed publications and conference presentations. TRIAL REGISTRATION NUMBER: jRCTs041210154.

RESUMEN

BACKGROUND: Fasting hypoglycemia is a recognized occurrence among pediatric patients with acute lymphoblastic leukemia (ALL) during maintenance therapy. Existing publications describing this finding are limited to small studies and case reports. Our objective was to determine the incidence of hypoglycemia during maintenance chemotherapy and to investigate the association of age, as well as other potential risk factors, with this outcome in pediatric patients with ALL. PROCEDURE: This retrospective cohort study included individuals 1 to 21 years of age with ALL treated with antimetabolite-containing maintenance chemotherapy at a large children's hospital between January 2011 and December 2014. The primary endpoint was time to first documented episode of hypoglycemia during maintenance therapy, defined as single measurement of plasma glucose <60 mg/dL. Cox regression was used to evaluate the association with age and identify other potential risk factors. RESULTS: We identified 126 eligible patients, of whom 63% were documented as White, non-Hispanic, 28% as non-White, non-Hispanic, and 9% as Hispanic. Twenty-eight children (22%) had documented hypoglycemia during maintenance therapy. Younger age at the start of maintenance and hepatotoxicity documented during chemotherapy prior to maintenance initiation were associated with hypoglycemia (adjusted HR age = 0.88; 95% CI, 0.78-0.99; adjusted HR prior hepatotoxicity = 3.50; 95% CI, 1.47-8.36). CONCLUSIONS: Nearly one quarter of children in our cohort had hypoglycemia documented during maintenance chemotherapy. Younger age at maintenance initiation and hepatotoxicity during chemotherapy prior to maintenance initiation emerged as risk factors. These findings highlight the importance of counseling about the risk of, and monitoring for, hypoglycemia, particularly in young children.

RESUMEN

BACKGROUND: In the absence of randomised head-to-head trials, we conducted a population-adjusted indirect treatment comparison (PA-ITC) of phase III trial data to evaluate the relative efficacy and safety of maintenance olaparib and bevacizumab alone and in combination in patients with newly diagnosed, advanced ovarian cancer and a BRCA mutation (BRCAm). METHODS: An unanchored PA-ITC was performed on investigator-assessed progression-free survival (PFS) data. Individual patient data from SOLO1 (olaparib versus placebo) and from BRCA-mutated patients in PAOLA-1/ENGOT-ov25 (olaparib plus bevacizumab versus placebo plus bevacizumab) were pooled. Each arm of PAOLA-1 was weighted so that key baseline patient characteristics were similar to the SOLO1 cohort. Analyses were performed in patients with complete baseline data. Weighted Cox regression analysis was used to estimate the comparative efficacy of different maintenance therapy strategies, supplemented by weighted Kaplan-Meier analyses. RESULTS: Data from SOLO1 patients (olaparib, n = 254; placebo, n = 126) were compared with data from BRCA-mutated PAOLA-1 patients (olaparib plus bevacizumab, n = 151; placebo plus bevacizumab, n = 71). Adding bevacizumab to olaparib was associated with a numerical improvement in PFS compared with olaparib alone (hazard ratio [HR] 0.71; 95% confidence interval [CI] 0.45-1.09). Statistically significant improvements in PFS were seen with olaparib alone versus placebo plus bevacizumab (HR 0.48; 95% CI 0.30-0.75), olaparib plus bevacizumab versus placebo (0.23; 0.14-0.34), and placebo plus bevacizumab versus placebo (0.65; 0.43-0.95). CONCLUSIONS: Results of this hypothesis-generating PA-ITC analysis support the use of maintenance olaparib alone or with bevacizumab in patients with newly diagnosed, advanced ovarian cancer and a BRCAm.

RESUMEN

Inhibitors of poly(ADP-ribose) polymerase (PARP) and angiogenesis have demonstrated single-agent activity in women with advanced ovarian cancer. Recent studies have aimed to establish whether combination therapy can augment the response seen with PARP inhibitors or antiangiogenic agents alone. This review provides an overview of PARP inhibitors and antiangiogenics as monotherapy in women with advanced ovarian cancer, explores potential mechanisms of action of PARP inhibitor and antiangiogenic combination treatments, reviews efficacy and safety data from trials evaluating this combination, and outlines ongoing and future trials evaluating this combination, discussing these in the context of the current and future treatment landscape for women with advanced ovarian cancer. Sentinel studies evaluating PARP inhibitor (n = 8), antiangiogenic (n = 4), and combination (n = 7) therapy were identified in women with newly diagnosed (n = 7) and recurrent (n = 12) ovarian cancer. PARP inhibitors included olaparib (n = 9), niraparib (n = 4), rucaparib (n = 1), and veliparib (n = 1). Antiangiogenic agents included bevacizumab (n = 7) and cediranib (n = 4). PARP inhibitors combined with antiangiogenics demonstrated efficacy based on objective response rates and progression-free survival (PFS) in the relapsed disease setting. Maintenance therapy with the PARP inhibitor, olaparib, plus antiangiogenic therapy offered a significant PFS benefit versus the antiangiogenic alone in women with newly diagnosed advanced ovarian cancer who tested positive for homologous recombination deficiency. Combination therapy was tolerated, with no new safety signals reported compared with monotherapy trials. PARP inhibitors and antiangiogenics have changed the landscape of ovarian cancer treatment. The PARP inhibitor plus antiangiogenic combination is a novel treatment option that appears promising in the first-line advanced and recurrent ovarian cancer settings, although the role of this combination in recurrent disease requires further elucidation. Defining which patients are candidates for monotherapy or combination therapy is critical, taking into consideration safety profiles of therapies alone or in combination, and how these treatments should be sequenced in clinical practice.

RESUMEN

BACKGROUND: Within pediatric oncology, parental decision making regarding participation in clinical trials that aim to reduce therapy to mitigate side effects is not well studied. The recently completed Children's Oncology Group trial for standard-risk acute lymphoblastic leukemia (AALL0932) included a reduction in maintenance therapy, and required consent for randomization immediately prior to starting maintenance. At our institution, 40% of children enrolled on AALL0932 were withdrawn from protocol therapy prior to randomization due to parental choice. This study sought to identify factors that impacted parental decision making regarding randomization on AALL0932. PROCEDURE: Parents of children enrolled on AALL0932 at our institution were eligible if their child met criteria for the average-risk randomization. Parents were invited to participate in a 30-50-minute phone interview. Questions focused on factors that shaped parental decision making about randomization, as well as their perspectives about the clinical trial experience more generally. RESULTS: Fear of receiving less therapy and subsequent relapse was the predominant reason to decline randomization. Reasons given for consenting to randomization included trust in the physician, altruism, hope for less therapy, and potential for fewer side effects. Parents also reflected on ways to support future families making decisions about clinical trial participation. CONCLUSION: While many parents recognize the importance of clinical trials aiming to mitigate side effects, the fear of their own child relapsing with less than standard therapy may dissuade them from study participation. Recognizing and addressing these concerns will be important for enrollment and retention in future clinical trials.

RESUMEN

BACKGROUND: Previous studies have suggested a significant relationship between hyposalivation and inhalation therapy-induced oropharyngeal problems. However, salivary secretion tests are not widely performed in daily clinical practice. In fact, xerostomia, the complaint of dry mouth, may not indicate hyposalivation. Therefore, we determined the clinical factors associated with hyposalivation in patients with asthma. METHODS: This study is a post-hoc analysis of our previous studies. Adult patients with asthma on maintenance inhalation therapy were enrolled. The participants completed questionnaires on oropharyngeal symptoms and underwent a salivary secretion test. Symptom severity was evaluated using a numerical rating scale (NRS), and salivary secretion was measured using the modified cotton roll method. Using logistic regression analysis, we identified the clinical factors associated with hyposalivation. RESULTS: In total, 531 patients completed the questionnaire (43.8 ± 16.9 years and male/female = 171/360), and 234 patients successfully performed a salivary secretion test, of which 126 (53.8%) were diagnosed with hyposalivation (<0.25 g/min). The patients with hyposalivation were significantly older (p < 0.0001) and had severe xerostomia and/or gastroesophageal reflux-like symptoms (GERLS) (p < 0.0001). Many of these patients had also used inhaled long-acting beta agonists (p = 0.012) and high-dose inhaled corticosteroids (p = 0.024). Multivariate analysis revealed that advanced age (odds ratio [OR] 1.05, p < 0.0001), severe xerostomia (OR 1.02, p = 0.0006) and severe GERLS (OR 1.02, p = 0.001) were independently and significantly associated with hyposalivation. CONCLUSIONS: Age, xerostomia, and GERLS were significantly related to hyposalivation in patients with asthma. To identify oropharyngeal problems in these patients, a careful assessment of the suspected symptoms of gastroesophageal reflux may be useful.

RESUMEN

BACKGROUND: Although induction chemotherapy results in remission in many older patients with acute myeloid leukemia (AML), relapse is common and overall survival is poor. METHODS: We conducted a phase 3, randomized, double-blind, placebo-controlled trial of the oral formulation of azacitidine (CC-486, a hypomethylating agent that is not bioequivalent to injectable azacitidine), as maintenance therapy in patients with AML who were in first remission after intensive chemotherapy. Patients who were 55 years of age or older, were in complete remission with or without complete blood count recovery, and were not candidates for hematopoietic stem-cell transplantation were randomly assigned to receive CC-486 (300 mg) or placebo once daily for 14 days per 28-day cycle. The primary end point was overall survival. Secondary end points included relapse-free survival and health-related quality of life. RESULTS: A total of 472 patients underwent randomization; 238 were assigned to the CC-486 group and 234 were assigned to the placebo group. The median age was 68 years (range, 55 to 86). Median overall survival from the time of randomization was significantly longer with CC-486 than with placebo (24.7 months and 14.8 months, respectively; P<0.001). Median relapse-free survival was also significantly longer with CC-486 than with placebo (10.2 months and 4.8 months, respectively; P<0.001). Benefits of CC-486 with respect to overall and relapse-free survival were shown in most subgroups defined according to baseline characteristics. The most common adverse events in both groups were grade 1 or 2 gastrointestinal events. Common grade 3 or 4 adverse events were neutropenia (in 41% of patients in the CC-486 group and 24% of patients in the placebo group) and thrombocytopenia (in 22% and 21%, respectively). Overall health-related quality of life was preserved during CC-486 treatment. CONCLUSIONS: CC-486 maintenance therapy was associated with significantly longer overall and relapse-free survival than placebo among older patients with AML who were in remission after chemotherapy. Side effects were mainly gastrointestinal symptoms and neutropenia. Quality-of-life measures were maintained throughout treatment.

RESUMEN

Inflammatory bowel disease (IBD) in Asia has become increasingly prevalent. As a treatment of IBD, many immunomodulators and biological agents were introduced and shown to be effective in inducing and maintaining remission. However, many cases with treatment failure were reported. To overcome the failure, combination therapy of immunomodulatory and biologics have emerged, showing better outcomes by optimizing biologic pharmacokinetics and minimizing immunogenicity. Adversely, rates of tuberculosis (TB) have been increased as a result. The aim of this study is to compare the risk of TB according to the therapy using large population data.We used data from the South Korean Health Insurance and Review Agency over the period 2008-2016 and calculated the hazard ratio (HR) for TB in IBD. We compared the risk of TB according to the medication: infliximab only, azathioprine only (AZA), combination of azathioprine and infliximab (CAI), azathioprine monotherapy and infliximab monotherapy (AIM), and azathioprine and infliximab whether simultaneously or separately (AISS).In IBD patients, a total of 249 patients were identified as active TB. After one-to-one matching with age, sex and disease duration, the risks of TB were significantly higher in AZA group (HR, 2.06; 95% CI, 1.35-3.12, P < .001), AIM group (HR, 3.26; 95% CI, 1.18-9.05, P = .02), AISS group (HR, 3.50; 95% CI, 1.92-6.37, P < .001), and CAI group (HR, 5.67; 95% CI, 2.42-10.21, P < .001), and the HR increased gradually in this order. In UC patients, the results were in similar pattern, but this pattern was not observed in CD patients in our study.Our study shows that Korean IBD patients are at risk of TB, and the risk increases with usage of IBD medication; moreover, the risk is the highest if combination therapy is used. These results highlight the importance of screening for TB in IBD patients, especially in combination therapy.

RESUMEN

While the outcome of patients with multiple myeloma has significantly improved over the last two decades, the disease remains incurable for the majority of patients. With the advent of novel agents, there has been a shift towards prolonged therapy as opposed to fixed-duration therapy, aimed at improving progression-free survival and overall survival. Evidence favoring continuous therapy has emerged over the last 2 decades and in the context of maintenance after proteasome inhibitor plus immunomodulatory drug induction followed by high dose melphalan and stem cell transplantation, this leads to >80% overall survival at 5 years. Maintenance therapy specifically has been demonstrated to correlate with increasing depth of disease response with a significant proportion of patients who remain minimal residual disease positive at the end of induction therapy achieving minimal residual disease negativity with maintenance therapy both in clinical trials and selected real world populations. As the survival improves, it is crucial to identify patients who are projected to have better survival and spare them toxicities arising from indefinite maintenance therapy. The role of minimal residual disease in this context is being investigated in numerous clinical trials and in the next few years the goal should be to use this in a rational way to achieve the ability to identify patients who would require continuation or escalation of therapy to improve their projected survival as well as to identify the group of patients in whom maintenance therapy could perhaps be time-limited without compromising their survival. Here we review the evidence for maintenance therapy from the key trials in the past years, present an overview of the current landscape and our perspective of maintenance therapy in the future.

RESUMEN

BACKGROUND: In the phase 3 trial ARIEL3, maintenance treatment with the poly(ADP-ribose) polymerase (PARP) inhibitor rucaparib provided clinical benefit versus placebo for patients with recurrent, platinum-sensitive ovarian cancer. Here, we evaluate the impact of age on the clinical utility of rucaparib in ARIEL3. METHODS: Patients with platinum-sensitive, recurrent ovarian carcinoma with ≥2 prior platinum-based chemotherapies who responded to their last platinum-based therapy were enrolled in ARIEL3 and randomized 2:1 to rucaparib 600 mg twice daily or placebo. Exploratory, post hoc analyses of progression-free survival (PFS), patient-centered outcomes (quality-adjusted PFS [QA-PFS] and quality-adjusted time without symptoms or toxicity [Q-TWiST]), and safety were conducted in three age subgroups (<65 years, 65-74 years, and ≥75 years). RESULTS: Investigator-assessed PFS was significantly longer with rucaparib than placebo in patients aged <65 years (rucaparib n = 237 vs placebo n = 117; median, 11.1 vs 5.4 months; hazard ratio [HR]: 0.33 [95% confidence interval (95% CI) 0.25-0.43]; P < 0.0001) and 65-74 years (n = 113 vs n = 64; median, 8.3 vs 5.3 months; HR 0.43 [95% CI 0.29-0.63]; P < 0.0001) and numerically longer in patients aged ≥75 years (n = 25 vs n = 8; median, 9.2 vs 5.5 months; HR 0.47 [95% CI 0.16-1.35]; P = 0.1593). QA-PFS and Q-TWiST were significantly longer with rucaparib than placebo across all age subgroups. Safety of rucaparib was generally similar across the age subgroups. CONCLUSIONS: Efficacy, patient-centered outcomes, and safety of rucaparib were similar between age subgroups, indicating that all eligible women with recurrent ovarian cancer should be offered this therapeutic option, irrespective of age. https://clinicaltrials.gov/ct2/show/NCT01968213.

RESUMEN

Recently, there have been a few reports of rituximab (RTX)-induced Crohn's disease, but there is no literature available on successful long-term treatment and the clinical outcome of this condition. We retrospectively analyzed the clinical data of a rare case of Crohn's disease induced by RTX administered as induction and prolonged maintenance therapy of a follicular lymphoma, diagnosed synchronously with a gastric signet ring cells carcinoma, treated at our hospital.

RESUMEN

There have been great advances in the management of ANCA associated vasculitis over the past decades. We have gone from an era where the disease was almost universally fatal to trying to prevent long-term side effects of treatment regimens. With the ability to use pulse cyclophosphamide or rituximab as alternates to oral cyclophosphamide for induction of remission, side effects of therapy have been greatly reduced. New approaches have drastically changed our approach to maintenance and we now favor much longer durations of maintenance therapy, as they are more successful in preventing relapse. Steroids have long been the bane of treatment as they are associated with a significant risk of infection and metabolic consequences. We are now in a steroid-sparing and looking ahead to a steroid-free era with new data being published showing lower doses of steroids being equally effective and several ongoing seminal trials looking at agents that could completely replace steroids very early on.

RESUMEN

OBJECTIVE: The aim of this study was to investigate the correlation between BRCA mutational status and response to bevacizumab in a large advanced ovarian cancer (AOC) series. METHODS: This is a multicenter, retrospective case-control study including upfront AOC treated between January 2015 and June 2019. The main inclusion criteria were: having received three weekly carboplatin-paclitaxel as first-line treatment, with or without Bevacizumab maintenance, knowledge of the BRCA mutational status. RESULTS: Overall, 441 patients were included; 183 (41.5%) patients received bevacizumab (Cases), and 258 (58.5%) did not receive it (Controls). The BRCA mutated patients (BRCAmut) were 58 (39%) in the Cases group and 90 (34.9%) in the Controls group (p = .77). Patients who received bevacizumab had a significant 4-months increase in median progression free survival (mPFS: 21 vs. 17 months, p = .033). Concerning BRCAmut patients, no differences were shown between those who received bevacizumab or not in terms of mPFS (24 vs. 22 months, p = .3). Conversely, in BRCA wild-type (BRCAwt) population bevacizumab administration significantly prolonged mPFS (20 vs 15 months, p = .019). At multivariate analysis, independent factors of prolonged PFS were BRCA status (OR = 0.60), having received PDS (OR = 0.69), and complete cytoreduction (OR = 0.50), but not the bevacizumab administration (OR = 0.83, p = .22). CONCLUSIONS: No evidence of oncological benefit in terms of PFS and OS related to bevacizumab maintenance therapy was found in BRCAmut patients. Differently, BRCAwt patients seem to benefit from antiangiogenic treatment in terms of mPFS.

RESUMEN

Aim: This study was conducted to investigate the effects of VKORC1, CYP2C9, CYP4F2 and EPHX1 and nongenetic factors on warfarin maintenance dose in a very elderly, frail Han-Chinese population. Materials & methods: 16 variants of VKORC1, CYP2C9, CYP4F2 and EPHX1 were genotyped. Univariate analysis and multivariable regression model were performed for the associations of gene variants and warfarin maintenance dose. Results & conclusion:EPHX1 rs2260863 nonvariant CC homozygotes required significantly lower daily warfarin dose than GC heterozygotes. In the multivariable model, VKORC1 rs9923231, CYP2C9 rs1057910, EPHX1 rs2260863, CYP4F2 rs2189784 and body surface area altogether explained 26.9% of dosing variability. This study revealed the main impact of genetic factors on warfarin response in this special population.
