MiRNA biomarkers for eribulin response

Accession Number: GSE87902 Platform: GPL22556: Applied Biosystems, TaqMan® Low Density Array (TLDA) Human MicroRNA Cards v3.0 Organism: Homo sapiens Published on 2017-02-20 Summary: Background: Recent phase II and III clinical trials demonstrated antitumor activity of eribulin, a tubulin-interacting cytotoxic agent, in patients with metastatic soft tissue sarcoma (STS). In this exploratory study we aimed to identify putative microRNA biomarkers that associate with eribulin sensitivity or resistance in STS. Materials and methods: Archival tumor tissue from primary tumors or metastatic lesions was collected prior to eribulin treatment, from 65 consenting patients involved in the EORTC trial 62052. This phase II study (ClinicalTrials.gov identifier NCT00413192) included multiple subtypes of STS. Tissue was available from 21 leiomyosarcomas, 14 adipocytic sarcomas, 9 synovial sarcomas and 21 other sarcoma histotypes. Total RNA was isolated from formalin fixed, paraffin embedded tumor samples and analyzed using Taqman® Low Density Arrays to determine microRNA expression profiles. The expression of a total of 756 microRNAs was assessed. Progression free survival at week 12 (RECIST 1.0) measured as a binary variable, was the primary endpoint of the clinical trial and used as a primary response measure for correlative studies. Seventeen out of 53 (32.1%) evaluable patients in the analyzed subset had non-progressive disease at week 12 and were defined as responders. Results: The expression of 26 individual microRNAs (

Crizotinib in patients with advanced, inoperable inflammatory myofibroblastic tumours with and without anaplastic lymphoma kinase gene alterations (European Organisation for Research and Treatment of Cancer 90101 CREATE): a multicentre, single-drug, prospective, non-randomised phase 2 trial

International audienceBackgroundAn inflammatory myofibroblastic tumour (IMFT) is a rare mesenchymal neoplasm characterised by anaplastic lymphoma kinase (ALK) gene rearrangements. We assessed the activity and safety of crizotinib, a tyrosine kinase inhibitor, targeting ALK in patients with advanced IMFT either with or without ALK alterations.MethodsWe did a multicentre, biomarker-driven, single-drug, non-randomised, open-label, two-stage phase 2 trial (European Organisation for Research and Treatment of Cancer 90101 CREATE) at 13 study sites (five university hospitals and eight specialty clinics) in eight European countries (Belgium, France, Germany, Italy, Netherlands, Poland, Slovakia, and the UK). Eligible participants were patients aged at least 15 years with a local diagnosis of advanced or metastatic IMFT deemed incurable with surgery, radiotherapy, or systemic therapy; measurable disease; an Eastern Cooperative Oncology Group performance status of 0–2; and adequate haematological, renal, and liver function. Central reference pathology was done for confirmation of the diagnosis, and ALK positivity or negativity was assessed centrally using immunohistochemistry and fluorescence in-situ hybridisation based on archival tumour tissue and defined as ALK immunopositivity or rearrangements in at least 15% of tumour cells. Eligible ALK-positive and ALK-negative patients received oral crizotinib 250 mg twice per day administered on a continuous daily dosing schedule (the duration of each treatment cycle was 21 days) until documented disease progression, unacceptable toxicity, or patient refusal. If at least two of the first 12 eligible and assessable ALK-positive patients achieved a confirmed complete or partial response according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1, a maximum of 35 patients were to be enrolled. If at least six ALK-positive patients achieved a confirmed response, the trial would be deemed successful. The primary endpoint was the proportion of patients who achieved an objective response (ie, a complete or partial response) as per RECIST 1.1, with response confirmation assessed by the local investigator every other cycle. Activity and safety endpoints were analysed in the per-protocol population. This trial is registered with ClinicalTrials.gov, number NCT01524926.FindingsBetween Oct 3, 2012, and April 12, 2017, we recruited and treated 20 eligible participants, 19 of whom were assessable for the primary endpoint. Median follow-up was 863 days (IQR 358–1304). Six of 12 ALK-positive patients (50%, 95% CI 21·1–78·9) and one of seven ALK-negative patients (14%, 0·0–57·9) achieved an objective response. The most common treatment-related adverse events in the 20 participants were nausea (11 [55%]), fatigue (9 [45%]), blurred vision (nine [45%]), vomiting (seven [35%]), and diarrhoea (seven [35%]). Eight serious adverse events occurred in five patients: pneumonia, fever of unknown cause, a heart attack with increased creatinine and possible sepsis, an abdominal abscess with acute renal insufficiency, and a QT prolongation.InterpretationWith 50% of participants with ALK-positive tumours achieving an objective response, crizotinib met the prespecified criteria for success in this trial. The results presented here support the rationale for inhibiting ALK in patients with IMFT. Crizotinib could be considered as the standard of care for patients with locally advanced or metastatic ALK-positive IMFT who do not qualify for curative surgery.FundingThe European Organisation for Research and Treatment of Cancer and Pfizer

Activity and safety of the multi-target tyrosine kinase inhibitor cabozantinib in patients with metastatic gastrointestinal stromal tumour after treatment with imatinib and sunitinib: European Organisation for Research and Treatment of Cancer phase II trial 1317 'CaboGIST'

BACKGROUND: Gastrointestinal stromal tumour (GIST) is commonly treated with tyrosine kinase inhibitors (TKIs), but most patients ultimately develop secondary resistance. Cabozantinib, a multi-targeted TKI inhibitor, has activity in patient-derived GIST mouse xenograft models and can overcome compensatory MET signalling occurring on TKI treatment. European Organisation for Treatment of Cancer (EORTC) 1317 'CaboGIST' assessed the safety and activity of cabozantinib in patients with GIST who had progressed on imatinib and sunitinib. METHODS: In this multi-center, open label, single arm phase II study, eligible GIST patients received oral cabozantinib (60 mg) once daily. Primary end-point was the progression-free survival rate at 12 weeks assessed by the local investigator per Response Evaluation Criteria in Solid Tumours 1·1. If at least 21 of the first 41 eligible and evaluable patients were progression-free at week 12, the activity of cabozantinib was sufficient to warrant further exploration according to the A'Hern one-stage study design. FINDINGS: A total of 50 eligible patients started treatment between 02/2017 and 08/2018, including four (8%) still continuing cabozantinib at clinical cut-off (09/2019). The number of 3-weekly treatment cycles ranged from 1 to 30. Among the first 41 eligible and evaluable patients, 24 were progression-free at week 12 (58·5%, 95% confidence interval [CI] 42·0-74·0%). Among all 50 patients, 30 were progression-free at week 12 (60%, 95% CI 45-74%). Seven patients achieved a partial response (14%, 95% CI 6-27%), and 34 had stable disease (68%, 95% CI 53-80%) as best response. Progression was seen in eight patients (16%, 95% CI 7-29%), and one was not evaluable. Disease control was achieved in 41 patients (82%, 95% CI 69-91%). Median progression-free survival was 5·5 months (95% CI 3·6-6·9). The most common adverse events were diarrhoea (76%), palmar-plantar erythrodysesthesia syndrome (60%), fatigue (50%), hypertension (42%), weight loss (40%) and oral mucositis (30%), with 32 (64%) patients requiring dose reductions, 27 (54%) having treatment interruptions and no cabozantinib-related deaths observed. INTERPRETATION: EORTC 1317 met its primary end-point, with 24/41 patients being progression-free at week 12 of treatment. The objective response was 14% with an encouraging disease control rate of 82%. Results of this trial confirm preclinical findings and warrant further exploration of cabozantinib in GIST.
