Immuno-priming with bevacizumab: durvalumab plus bevacizumab after prolonged exposition to bevacizumab in breast cancer

Project description:Purpose: To study the potential priming benefit of bevacizumab from subsequent immunotherapy (durvalumab) in advanced breast cancer patients Methods: We tested this hypothesis by adding durvalumab after progression to maintenance single-agent bevacizumab treatment in advanced HER2-negative patients (average 3 treatment lines). In order to study the potential priming benefit, patients had to experience disease progression while on bevacizumab maintenance prior to entering the trial. In addition, we sought to find traits in peripheral-blood mononuclear cells (PBMCs) and tumor biopsies that informed about this immuno-priming, in an attempt to search for novel biomarkers of efficacy of the combo and obtain a better understanding of the biology of this clinical scenario. Results: Patients that experienced clinical benefit, compared with the remaining patients, displayed a lymphocyte pattern in PBMCs consisting on increased T-effector subpopulations (CD4- and CD8- effector and effector-memory) and decreased immunosuppressive T-regulatory cells. Gene-expression studies in tumor samples showed a congruent pattern, with increased T-effector and memory T cell signatures in responders, and increased T-regulatory and decreased active dendritic cells in non-responders. These events were observed in patients that displayed vascular normalization features as a result of previous bevacizumab, supporting the immuno-priming effects of this strategy.

Gene expression profile of FFPE samples collected with translational purposes from the MITO16/MaNGO-OV2 clinical trial

Project description:MITO16/MaNGO-OV2 (NCT01706120) is a multicenter, phase IV, single arm trial for advanced stage IIIB-IV or recurrent, previously untreated, ovarian cancer patients receiving carboplatin, paclitaxel plus bevacizumab for six 3-weekly cycles followed by bevacizumab single agent until progression or unacceptable toxicity up to a maximum of 22 total cycles. The trial that was specifically designed with a translational primary endpoint to explore if selected clinical and biological factors could identify ovarian cancer patients with better prognosis in terms of progression free survival and overall survival after combined first-line treatment with chemotherapy plus Bevacizumab. The translational study, designed together with the clinical trial, the translational study implicated the collection of patients’ tissue (formalin-fixed paraffin-embedded – FFPE) and blood samples. Gene expression profile was among the molecular analyses proposed on FFPE samples.

Project description:This is a multicentric single arm, open label trial. In this study patients candidated to a first line of chemotherapy for metastatic colorectal cancer will be treated with 8 cycles of folfoxiri plus bevacizumab plus nivolumab followed by a maintenance with bevacizumab plus nivolumab. Patients who do not progress during chemotherapy phase will receive bevacizumab plus nivolumab as maintenance therapy. Patients will be treated until disease progression, unacceptable toxicity or patient/physician decision.

TAS-102, Irinotecan, and Bevacizumab in Pre-treated Metastatic Colorectal Cancer (TABAsCO), A Phase II Clinical Trial. ClinicalTrials.gov NCT04109924

Project description:Background: The efficacy of FOLFIRI plus an antiangiogenesis biologic agent as 2nd line therapy for metastatic colorectal adenocarcinoma is limited. TAS-102 is a novel oral antimetabolite with a distinct mechanism of action from fluoropyrimidines. We evaluated the antitumor efficacy of TAS-102, irinotecan and bevacizumab in patients with pre-treated, advanced colorectal adenocarcinoma in a multicenter, phase II, single-arm study. Methods: Patients with advanced colorectal adenocarcinoma who had progressed after oxaliplatin and fluoropyrimidine and were eligible for treatment with bevacizumab were treated with irinotecan, bevacizumab, and TAS-102 in 28-day cycles. The primary endpoint was progression-free survival (PFS). Results: We enrolled 35 evaluable patients. The study was positive. The median PFS was 7.9 (90% CI 6.2-11.8) months (vs. 6 months in historical control, p=0.018). The median overall survival was 16.5 (90% CI 9.8-17.5) months. Sixty-seven percent of patients experienced grade 3 or higher treatment-related adverse events. The most common toxicities were hematological (neutropenia) and gastrointestinal (diarrhea, nausea, and vomiting). Conclusions: Irinotecan, TAS-102 and bevacizumab is an active 2nd line therapy for patients with metastatic colorectal adenocarcinoma. Neutropenia is common and can affect dose density/intensity mandating use of G-CSF. A randomized study versus standard of care therapy is warranted.

A Study Comparing the Efficacy and Safety of Vanucizumab and FOLFOX With Bevacizumab and FOLFOX in Participants With Untreated Metastatic Colorectal Cancer

Project description:This is a Phase 2 multicenter, randomized, parallel arms, double-blind study of vanucizumab to evaluate the efficacy and safety of vanucizumab in combination with oxaliplatin, folinic acid, and 5-fluorouracil (5-FU) (mFOLFOX-6) versus bevacizumab (Avastin) + mFOLFOX-6 in participants with previously untreated metastatic colorectal cancer (mCRC). The study consists of 2 parts: a safety run-in open-label, single-arm part (Part 1) and a randomized, parallel-arms, double-blind part (Part 2). During Part 1 at least 6 eligible participants will receive 2000 milligrams (mg) vanucizumab every 2 weeks + mFOLFOX-6 in order to confirm the dose and schedule that will be used in Part 2. In Part 2, all eligible participants will be randomized in a ratio of 1:1 to receive either mFOLFOX-6 + vanucizumab or mFOLFOX-6 + bevacizumab. Study treatment (induction and maintenance) will be given on Day 1 of each 14-day cycle. Induction therapy will consist of up to 8 cycles of mFOLFOX-6 plus either bevacizumab or vanucizumab. Maintenance therapy will consist of 5-fluorouracil and folinic acid plus either vanucizumab or bevacizumab for up to 24 months or until disease progression, unacceptable toxicity, Investigator decision or consent withdrawal, whichever occurs first.

FOLFOXIRI Plus Cetuximab vs. FOLFOXIRI Plus Bevacizumab 1st-line in BRAF-mutated mCRC

Project description:Once randomisation has been completed, the study treatment should be started preferably immediately; at the latest within one week following randomisation. The patients will be randomised in a ratio of 1:2 to the following two treatment arms. Patients in both treatment arms will receive standard chemotherapy with FOLFOXIRI as background treatment, which can be de-escalated to FOLFIRI in case of toxicity. Standard arm A: The patient will be treated with FOLFOXIRI plus bevacizumab for up to 12 cycles (24 weeks) or until progression (if the latter occurs before completing the 12 cycles). Within the 12 cycles, the FOLFOXIRI plus bevacizumab regimen may be de-escalated, owing to toxicity, to FOLFIRI and bevacizumab at the treating physician’s discretion. After 12 cycles of the study treatment, a switch to a maintenance regimen with a fluoropyrimidine (5-FU infusion or capecitabine) plus bevacizumab, administered until progression occurs, is recommended. The recommended maintenance phase of the study is not part of the study treatment. However, maintenance therapy will be counted as first-line therapy. Experimental arm B: The patient will be treated with FOLFOXIRI plus weekly administration of cetuximab for up to 12 cycles (24 weeks) or until progression (if the latter occurs before completing the 12 cycles). Within the 12 cycles, the FOLFOXIRI plus cetuximab regimen may be de-escalated owing to toxicity, to FOLFIRI and cetuximab at the treating physician’s discretion. After 12 cycles, a switch to a maintenance regimen with 5-FU and cetuximab or with irinotecan and cetuximab, administered until progression occurs, is recommended. The recommended maintenance phase of the study is not part of the study treatment. However, maintenance therapy will be counted as first-line therapy.
