RESUMO

BACKGROUND: Studies on the efficacy of rituximab in Primary CNS Lymphoma (PCNSL) reported conflicting results. Our international randomized phase III study showed that the addition of rituximab to high-dose methotrexate, BCNU, teniposide and prednisolone (MBVP) in PCNSL was not efficacious on the short-term. Here we present long-term results after a median follow-up of 82.3 months. METHODS: 199 eligible newly-diagnosed, non-immunocompromised patients with PCNSL aged 18-70 years with WHO performance status 0-3 were randomized between treatment with MBVP chemotherapy with or without rituximab, followed by high-dose cytarabine consolidation in responding patients, and reduced-dose WBRT in patients aged ≤60 years. Event-free survival was the primary endpoint. Overall survival rate, neurocognitive functioning (NCF), and health-related quality of life (HRQoL) were additionally assessed, with the IPCG test battery, EORTC QLQ-C30 and QLQ-BN20 questionnaires, respectively. RESULTS: For event-free survival, the hazard ratio was 0.85, 95% confidence interval 0.61-1.18, p=0.33. Overall survival rate at 5 years for MBVP and R-MBVP was 49% (39-59) and 53% (43-63) respectively. In total, 64 patients died in the MBVP arm and 55 in the R-MBVP arm, of which 69% due to PCNSL. At group level, all domains of NCF and HRQoL improved to a clinically relevant extent after treatment initiation, and remained stable thereafter up to 60 months of follow-up, except for motor speed which deteriorated between 24 and 60 months. Although fatigue improved initially, high levels persisted in the long-term. CONCLUSION: Long-term follow-up confirms lack of added value of rituximab in addition to MBVP and HD-cytarabine for PCNSL.

RESUMO

Primaquine is an important antimalarial drug for malaria transmission blocking and radical cure, but it is not currently available in child-friendly formulations in appropriate doses. Adult-strength tablets are often crushed and dissolved in water to obtain the required dose, which exposes the drug's bitter taste. As part of the developing paediatric primaquine (DPP) project, this study adopted a responsive sensory pharmaceutics approach by integrating real-time formulation development and pre-clinical taste assessment to develop palatable, flavour-infused primaquine tablets. A design of experiment (DoE) approach was used to screen different taste-masking agents and excipient blends with trained, expert sensory assessors, with quinine hydrochloride as a model bitter tastant. The taste-masking efficacy of selected prototype formulation blends was validated with naïve assessors using the highest 15 mg primaquine dose. The mean bitterness intensity rating, measured on a discrete 11-point scale, was halved from 7.04 for the unflavoured control to 2.74-3.70 for the formulation blends. Sucralose had the biggest impact on bitterness suppression and improving palatability. Two different flavouring systems have been developed, and their acceptability in paediatric patients will be assessed as part of upcoming validation field clinical trials in Africa.

RESUMO

High-dose intravenous methotrexate (HD-MTX) CNS prophylaxis in high-risk diffuse large B cell lymphoma (DLBCL) remains controversial. We describe real-world CNS relapse incidence following baseline cerebrospinal fluid (CSF) analysis to exclude asymptomatic leptomeningeal involvement in newly diagnosed high-risk DLBCL patients with versus without single-route HD-MTX CNS prophylaxis. Consecutively diagnosed high-risk systemic DLBCL patients without leptomeningeal involvement by CSF analysis (noCNS) were identified retrospectively. Five-year CNS relapse incidence and survival outcomes were examined, as stratified by receipt of HD-MTX prophylaxis. Secondary analysis of survival outcomes in patients with synchronous leptomeningeal involvement (CNSinv) by CSF analysis at diagnosis were compared with the noCNS group. No significant difference in 5-year CNS relapse incidence was observed following HD-MTX prophylaxis versus no prophylaxis (total n = 445) despite similar CNS-IPI risk; 6.2% versus 5.6%, adjusted HR 1.08 (95% CI 0.41-2.85), p = .88; nor in 5-year progression free survival (PFS) or overall survival (OS) risk. Of CNSinv patients, 93.3% had ≥1 extranodal site. Increased CNS relapse/progression risk (5-year risk; HR 10.7 [95% CI 5.35-21.37], p < .0001) and inferior PFS and OS were observed in CNSinv versus all noCNS patients. The CNSinv group had superior OS compared with noCNS patients who later experienced CNS relapse (HR 0.55, p = .052). HD-MTX prophylaxis does not reduce CNS relapse risk in high-risk systemic DLBCL without leptomeningeal involvement by CSF analysis at diagnosis. Asymptomatic patients with synchronous leptomeningeal involvement on baseline CSF examination are at increased risk of further CNS disease events and inferior survival compared to patients without CSF involvement.

RESUMO

The normal umbilical cord is a crucial component during pregnancy, but sometimes it could become compromised due to some abnormalities such as excessive long umbilical cord, and though they usually end up with a healthy baby, they may lead to severe consequences. Excessive long umbilical cords are found in 4% of pregnancies and represent a risk factor for nuchal cords and true knots. We report a case of a 37-year-old Syrian pregnant woman who presented to the hospital at 37 weeks of gestation asking for a C-section for a fear of ambiguous ultrasound findings that have been interpreted as fetal malformation. At delivery, a healthy baby was born with a 150-cm umbilical cord, a true knot, and double-looped nuchal cords; the formation of the loops and the knot had been attributed to the elongated cord. Besides, ultrasound imaging could sometimes be deceptive and lead to unnecessary interventions; therefore, cord anomalies should always be kept in mind because they do not always represent a justification for a C-section.

RESUMO

BACKGROUND: In primary central nervous system lymphoma (PCNSL), small enhancing lesions can persist after treatment. It is unknown whether a difference in response category (complete response [CR], complete response unconfirmed [CRu], or partial response [PR]) reflects survival. We aimed to determine the value of a central radiology review on response assessment and whether the extent of response influenced progression-free and/or overall survival. METHODS: All patients in the HOVON 105/ALLG NHL 24 study with at least a baseline MRI and one MRI made for response evaluation available for central review were included. Tumor measurements were done by 2 independent central reviewers, disagreements were adjudicated by a third reviewer. Crude agreement and interobserver agreement (Cohen's kappa) were calculated. Differences in progression-free and overall survival between different categories of response at the end-of-protocol-treatment were assessed by the log-rank test in a landmark survival-analysis. RESULTS: Agreement between the central reviewers was 61.7% and between local and central response assessment was 63.0%. Cohen's kappa's, which corrects for expected agreement, were 0.44 and 0.46 (moderate), respectively. Progression agreement or not was 93.3% (kappa 0.87) between local and central response assessment. There were no significant differences in progression-free and overall survival between patients with CR, CRu, or PR at the end-of-protocol-treatment, according to both local and central response assessment. CONCLUSIONS: Reliability of response assessment (CR/CRu/PR) is moderate even by central radiology review and these response categories do not reliably predict survival. Therefore, primary outcome in PCNSL studies should be survival rather than CR or CR/CRu-rate.

RESUMO

INTRODUCTION: To assess the value of the Mini-Mental State Examination (MMSE)-score at baseline in predicting survival in adult primary central nervous system lymphoma (PCNSL) patients. METHODS: In the HOVON 105/ ALLG NHL 24 phase III study patients with newly-diagnosed PCNSL were randomized between high-dose methotrexate-based chemotherapy with or without rituximab. Data on potential (MMSE-score), and known baseline prognostic factors (age, performance status, serum LDH, cerebrospinal fluid total protein, involvement of deep brain structures, multiple cerebral lesions, and the IELSG-score) were collected prospectively. Multivariable stepwise Cox regression analyses were used to assess the prognostic value of all factors on progression-free survival (PFS) and overall survival (OS) among patients with available MMSE score at baseline. Age was analyzed as continuous variable, the MMSE-score both as a continuous and as a categorical variable. RESULTS: In univariable analysis, age, MMSE-score and whether the patient received rituximab were statistically significantly prognostic factors for PFS. Age and MMSE-score were statistically significantly associated with OS. In a multivariable analysis of the univariately significant factors only MMSE-score was independently associated with the survival endpoints, as a continuous variable (HR for PFS 1.04, 95% CI 1.01-1.08; OS 1.06 (95% CI 1.02-1.10) and as categorical variable HR (< 27 versus ≥ 27 for PFS 1.55 (1.02-2.35); OS 1.68 (1.05-2.70). In our population, performance status, serum LDH, and CSF protein level were not of prognostic value. CONCLUSION: Neurocognitive disturbances, measured with the MMSE at baseline, are an unfavorable prognostic factor for both PFS and OS in adult PCNSL patients up to 70 years-old.

RESUMO

BACKGROUND: To analyze the effect of treatment on neurocognitive functioning and the association of neurocognition with radiological abnormalities in primary central nervous system lymphoma (PCNSL). METHODS: One hundred and ninety-nine patients from a phase III trial (HOVON 105/ALLG NHL 24), randomized to standard chemotherapy with or without rituximab, followed in patients ≤60 years old by 30-Gy whole-brain radiotherapy (WBRT), were asked to participate in a neuropsychological evaluation before and during treatment, and up to 2 years posttreatment. Scores were transformed into a standardized z-score; clinically relevant changes were defined as a change in z-score of ≥1 SD. The effect of WBRT was analyzed in irradiated patients. All MRIs were centrally assessed for white matter abnormalities and cerebral atrophy, and their relation with neurocognitive scores over time in each domain was calculated. RESULTS: 125/199 patients consented to neurocognitive evaluation. Statistically significant improvements in neurocognition were seen in all domains. A clinically relevant improvement was seen only in the motor speed domain, without differences between the arms. In the follow-up of irradiated patients (n = 43), no change was observed in any domain score, compared to after WBRT. Small but significant inverse correlations were found between neurocognitive scores over time and changes in white matter abnormalities (regression coefficients: -0.048 to -0.347) and cerebral atrophy (-0.212 to -1.774). CONCLUSIONS: Addition of rituximab to standard treatment in PCNSL patients did not impact neurocognitive functioning up to 2 years posttreatment, nor did treatment with 30-Gy WBRT in patients ≤60 years old. Increased white matter abnormalities and brain atrophy showed weak associations with neurocognition.

RESUMO

Primary and secondary central nervous system lymphomas (PCNSL/SCNSL) are aggressive rare malignancies with dismal outcomes. Encouraging data have emerged from Phase I/II clinical trials treating relapsed/refractory PCNSL/SCNSL with ibrutinib. We analysed 33 patients who received ibrutinib, alone or with other therapies, for PCNSL (n = 9) or SCNSL (n = 24). The objective response rate was 58% (complete response 55%). The median progression-free survival and overall survival for patients with PCNSL were both 3·1 months; for SCNSL, 10·2 and 11·5 months respectively. Only one invasive fungal infection was observed, despite concurrent or recent use of dexamethasone 8-16 mg daily in 14 patients (42%). Ibrutinib has encouraging activity in these aggressive malignancies.

RESUMO

Bing-Neel syndrome (BNS) is characterised by infiltration of the central nervous system by lymphoplasmacytic lymphoma (LPL) cells and is traditionally regarded as a complication of pre-existing systemic Waldenström's macroglobulinaemia (WM). We describe the case of a 49 year old woman with leptomeningeal LPL who did not fulfil diagnostic criteria for concomitant systemic WM at presentation, and who failed to respond to conventional chemotherapy treatment (including high dose methotrexate) but did respond to the oral Bruton tyrosine kinase (BTK) inhibitor ibrutinib. This highlights an important variation in the typical natural history of this rare disease and also further supplements emerging evidence regarding efficacy of ibrutinib in its treatment.

RESUMO

The CD-20 antibody rituximab is a standard component of treatment of non-Hodgkin B-cell lymphomas, including diffuse large B-cell lymphoma (DLBCL). Primary DLBCL of the central nervous system, also called primary central nervous system lymphoma (PCNSL), is a DLBCL confined to the central nervous system. There has been debate whether intravenous rituximab accumulates sufficiently in the central nervous system to exert an effect. In this systematic review, we assess the benefits and harms of rituximab in the treatment of immunocompetent patients with PCNSL. By searching MEDLINE, CENTRAL, and ClincialTrials.gov up to March 2019, we identified randomized controlled trials (RCTs) investigating the effect of rituximab in patients with PCNSL. We extracted study characteristics and results, assessed risk of bias, performed trial-level random-effects meta-analyses, and graded the certainty of evidence. The protocol was registered with PROSPERO (CRD42019121965). Main outcomes were overall survival (time to death), progression-free survival (time to progression or death), quality of life, grades 3 and 4 toxicity, and treatment-related mortality. We included two RCTs with a total of 343 participants. Overall survival was not statistically significantly improved (HR 0.76; 95% CI, 0.52-1.12; low certainty), with 187 fewer to 39 more deaths after 2 years in 1000 treated patients. Low certainty of evidence indicated that rituximab improved progression-free survival (HR 0.65; 95% CI, 0.45-0.95), which translated into 137 fewer progressions or deaths after 2 years in 1000 treated patients (231 to 18 fewer). None of the RCTs provided data on quality of life. We found no evidence that rituximab increased grades 3 and 4 toxicity or treatment-related mortality (RR 0.53; 95% CI, 0.20-1.37; low certainty). Overall, the available evidence suggests with low certainty that rituximab in combination with methotrexate-based chemotherapy may improve progression-free survival in immunocompetent patients with newly diagnosed PCNSL, the pooled effect estimates did not show evidence for improvement of overall survival.

RESUMO

For over half a century, the carbazole skeleton has been the key structural motif of many biologically active compounds including natural and synthetic products. Carbazoles have taken an important part in all the existing anti-cancer drugs because of their discovery from a large variety of organisms, including bacteria, fungi, plants, and animals. In this article, we specifically explored the literature from 2012 to 2018 on the anti-tumour activities reported to carbazole derivatives and we have critically collected the most significant data. The most described carbazole anti-tumour agents were classified according to their structure, starting from the tricyclic-carbazole motif to fused tetra-, penta-, hexa- and heptacyclic carbazoles. To date, three derivatives are available on the market and approved in cancer therapy.

RESUMO

PURPOSE: The BRIGHT study ( ClinicalTrials.gov identifier: NCT00877006) was initiated to compare the efficacy and safety of bendamustine plus rituximab (BR) with either rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) or rituximab plus cyclophosphamide, vincristine, and prednisone (R-CVP) for treatment-naive patients with indolent non-Hodgkin lymphoma or mantle-cell lymphoma. This publication provides long-term follow-up data. PATIENTS AND METHODS: Patients were monitored for a minimum of 5 years after completion of study treatment for the time-to-event end points of progression-free survival (PFS), event-free survival, duration of response, and overall survival per investigator assessment. Data on the number of patients who received second-line anticancer treatment and the occurrence of other malignancies were also collected. RESULTS: The medians were not reached for any of the time-to event end points for either the BR or R-CHOP/R-CVP study treatment groups by study completion. PFS rates at 5 years were 65.5% in the BR treatment group and 55.8% in the R-CHOP/R-CVP group. The difference in PFS was considered significant with a hazard ratio of 0.61 (95% CI, 0.45 to 0.85; P = .0025). The hazard ratio for event-free survival and duration of response (P = .0020 and .0134, respectively) also favored the BR regimen over R-CHOP/R-CVP. However, no significant difference in overall survival was observed. The overall safety profiles of BR, R-CHOP, and R-CVP were as expected; no new safety data were collected during long-term follow-up. A higher number of secondary malignancies was noted in the BR treatment group. CONCLUSION: Overall, BR demonstrated better long-term disease control than R-CHOP/R-CVP and should be considered as a first-line treatment option for patients with indolent and mantle-cell lymphoma.

RESUMO

BACKGROUND: The prognosis for primary CNS lymphoma has improved with the use of high-dose methotrexate-based chemotherapy, but patient outcomes remain poor. Rituximab, a chimeric monoclonal antibody that targets the CD20 cell surface protein, has substantial activity in systemic CD20-positive diffuse large B-cell lymphoma, but its efficacy in primary CNS lymphoma is unknown and low penetration of the large rituximab molecule through the blood-brain barrier could limit its effect. We aimed to investigate the addition of rituximab to a high-dose methotrexate-based chemotherapy regimen in patients with newly diagnosed primary CNS lymphoma. METHODS: This intergroup, multicentre, open-label, randomised phase 3 study was done at 23 hospitals in the Netherlands, Australia, and New Zealand. Non-immunocompromised patients aged 18-70 years with newly diagnosed primary CNS lymphoma were randomly assigned (1:1) to receive methotrexate-based chemotherapy with or without intravenous rituximab. We used a web-based randomisation system with stratification by centre, age, and Eastern Cooperative Oncology Group-WHO performance status, and a minimisation procedure. All group assignment was open label and neither investigators nor patients were masked to allocation. All patients were treated with two 28-day cycles of induction chemotherapy, consisting of intravenous methotrexate 3 g per m2 on days 1 and 15, intravenous carmustine 100 mg per m2 on day 4, intravenous teniposide 100 mg per m2 on days 2 and 3, and oral prednisone 60 mg per m2 on days 1-5, with (R-MBVP) or without (MBVP) intravenous rituximab 375 mg per m2 on days 0, 7, 14, and 21 in cycle one and days 0 and 14 in cycle two. Patients with response at the end of induction subsequently received high-dose cytarabine and, in patients aged 60 years or younger, low-dose whole-brain radiotherapy. The primary endpoint was event-free survival, with events defined as not reaching complete response or complete response unconfirmed at the end of treatment, or progression or death after response; analysis was adjusted for age and performance score. Patients were analysed on a modified intention-to-treat basis. This trial is registered with the Nederlands Trial Register, number NTR2427, and the Australian New Zealand Clinical Trials Registry, number ACTRN12610000908033. The trial was closed on May 27, 2016, after achieving complete accrual, and follow-up is ongoing. FINDINGS: Between Aug 3, 2010, and May 27, 2016, we recruited 200 patients (109 men and 91 women; median age was 61 years [IQR 55-67]). We randomly assigned 100 patients to MBVP and 99 patients to R-MBVP. One patient was randomly assigned to the R-MBVP group but found to be ineligible because of an incorrect diagnosis and was excluded from all analyses. After a median follow-up of 32·9 months (IQR 23·9-51·5), 98 patients had had an event (51 in the MBVP group and 47 in the R-MBVP group), of whom 79 had died (41 in the MBVP group and 38 in the R-MBVP group). Event-free survival at 1 year was 49% (95% CI 39-58) in the MBVP group (no rituximab) and 52% (42-61) in the R-MBVP group (with rituximab; hazard ratio 1·00, 95% CI 0·70-1·43, p=0·99). Grade 3 or 4 adverse events occurred in 58 (58%) patients in the MBVP group and 63 (64%) patients in the R-MBVP group, with infections (24 [24%] patients receiving MBVP vs 21 [21%] patients receiving R-MBVP), haematological toxicity (15 [15%] vs 12 [12%]), and nervous system disorders (ten [10%] vs 15 [15%]) being the most common. Life-threatening or fatal serious adverse events occurred in 12 (12%) patients in the MBVP group and ten (10%) patients in the R-MBVP group, and five (5%) patients in the MBVP group and three (3%) in the R-MBVP group died from treatment-related causes. INTERPRETATION: We found no clear benefit of addition of rituximab to methotrexate, carmustine, teniposide, and prednisone chemotherapy in primary CNS lymphoma. Therefore, the results of this study do not support the use of rituximab as a component of standard treatment in primary CNS lymphoma.

RESUMO

The treatment of patients with Bing-Neel syndrome (BNS) is not standardized. We included patients with Waldenström macroglobulinemia (WM) and a radiologic and/or cytologic diagnosis of BNS treated with ibrutinib monotherapy. Response assessment was based on criteria for BNS from the 8th International Workshop for WM. Survival from BNS diagnosis (BNS survival), survival from ibrutinib initiation to last follow-up or death (ibrutinib survival), and time from ibrutinib initiation to ibrutinib discontinuation for toxicity, progression, or death (event-free survival [EFS]) were estimated. Twenty-eight patients were included in our study. The median age at BNS diagnosis was 65 years. Ibrutinib was the first line of treatment for BNS in 39% of patients. Ibrutinib was administered orally at a dose of 560 and 420 mg once daily in 46% and 54% of patients, respectively; symptomatic and radiologic improvements were seen in 85% and 60% of patients within 3 months of therapy. At best response, 85% of patients had improvement or resolution of BNS symptoms, 83% had improvement or resolution of radiologic abnormalities, and 47% had cleared the disease in the cerebrospinal fluid. The 2-year EFS rate with ibrutinib was 80% (95% confidence interval [CI], 58%-91%), the 2-year ibrutinib survival rate was 81% (95% CI, 49%-94%), and the 5-year BNS survival rate was 86% (95% CI, 63%-95%). Ibrutinib therapy is effective in patients with BNS and should be considered as a treatment option in these patients.

Light chain deposition disease (LCDD) is a systemic disorder characterised by the pathologic deposition of immunoglobulin light chains, which is histologically distinguished from amyloidosis by failure to stain with Congo red. Central nervous system (CNS)-restricted LCDD is among the rarest manifestations. We describe a unique case complicated by focal onset epilepsy with impaired awareness for which control with anticonvulsant therapy proved difficult.

RESUMO

The aim of this study is to compare the risk of treatment-related toxicities and long-term survival between obese and nonobese patients with non-Hodgkin lymphoma when treated with full uncapped doses of R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) chemotherapy. A total of 133 patients and 733 cycles of chemotherapy were analyzed. Obese patients did not experience an increased risk of acute treatment-related toxicities (adjusted odds ratio 0.825, p = 0.197), or delayed toxicities (adjusted odds ratio 0.819, p = 0.779). In the subgroup of diffuse large B-cell lymphoma patients (n = 109), treatment response rate was similar between the two body mass index (BMI) groups, and obese patients tended to have superior overall and progression-free survivals, albeit not statistically significant. Full uncapped doses of R-CHOP chemotherapy administered to obese patients with non-Hodgkin lymphoma (NHL) are safe, well tolerated, and do not lead to inferior treatment response or long-term outcomes.

RESUMO

BACKGROUND: We previously reported results of the phase III, randomized, noninferiority trial comparing bendamustine-rituximab (BR) with standard R-CHOP (rituximab/cyclophosphamide/doxorubicin/vincristine/prednisone)/R-CVP (rituximab/cyclophosphamide/vincristine/prednisone) in previously untreated advanced indolent non-Hodgkin and mantle cell lymphomas. Here we report health-related quality of life (HRQOL) results from the trial. METHODS: HRQOL, as measured by the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30), was a secondary end point. Differences between group means in global health status (GHS), 5-item functioning, and 9 symptoms/single-item measures at week 1 of cycle 1 and end-of- cycles 3 and 6 were examined using the screening (baseline) score as a covariate in analysis of covariance. RESULTS: Overall EORTC QLQ-C30 compliance was 75.2%, 89.5%, and 89.9% at week 1 of cycle 1 and end-of-cycles 3 and 6, respectively. Patients treated with BR reported improvements in Cognitive Functioning, Physical Functioning, Social Functioning, Emotional Functioning, and GHS as well as reduction in dyspnea, constipation, and fatigue at some, but not all, time points. Patients treated with standard therapy reported less nausea/vomiting at one time point. CONCLUSION: Compared with patients treated with standard therapy, patients treated with BR reported better quality of life in several areas.

RESUMO

Four series of carbazole derivatives, including N-substituted-hydroxycarbazoles, oxazinocarbazoles, isoxazolocarbazolequinones, and pyridocarbazolequinones, were studied using diverse biological test methods such as a CE-based assay for CK2 activity measurement, a cytotoxicity assay with IPC-81 cell line, determination of MIC of carbazole derivatives as antibacterial agents, a Plasmodium falciparum susceptibility assay, and an ABCG2-mediated mitoxantrone assay. Two oxazinocarbazoles Ib and Ig showed CK2 inhibition with IC50 = 8.7 and 14.0 µM, respectively. Further chemical syntheses were realized and the 7-isopropyl oxazinocarbazole derivative 2 displayed a stronger activity against CK2 (IC50 = 1.40 µM). Oxazinocarbazoles Ib, Ig, and 2 were then tested against IPC-81 leukemia cells and showed the ability to induce leukemia cell death with IC50 values between 57 and 62 µM. Further investigations were also reported on antibacterial and antiplasmodial activities. No significant inhibitory activity on ABCG2 efflux pump was detected.

RESUMO

The Therapeutic Intensification in De Novo Leukaemia (TIDEL)-II study enrolled 210 patients with chronic phase chronic myeloid leukemia (CML) in two equal, sequential cohorts. All started treatment with imatinib 600 mg/day. Imatinib plasma trough level was performed at day 22 and if <1000 ng/mL, imatinib 800 mg/day was given. Patients were then assessed against molecular targets: BCR-ABL1 ≤10%, ≤1%, and ≤0.1% at 3, 6, and 12 months, respectively. Cohort 1 patients failing any target escalated to imatinib 800 mg/day, and subsequently switched to nilotinib 400 mg twice daily for failing the same target 3 months later. Cohort 2 patients failing any target switched to nilotinib directly, as did patients with intolerance or loss of response in either cohort. At 2 years, 55% of patients remained on imatinib, and 30% on nilotinib. Only 12% were >10% BCR-ABL1 at 3 months. Confirmed major molecular response was achieved in 64% at 12 months and 73% at 24 months. MR4.5 (BCR-ABL1 ≤0.0032%) at 24 months was 34%. Overall survival was 96% and transformation-free survival was 95% at 3 years. This trial supports the feasibility and efficacy of an imatinib-based approach with selective, early switching to nilotinib. This trial was registered at www.anzctr.org.au as #12607000325404.
