Filter by:This multicenter, randomized, double-blind study will evaluate the safety and efficacy of PM8002 in combination with Nab-Paclitaxel compared with placebo combined with Nab-Paclitaxel as first-line treatment in inoperable locally advanced/metastatic triple-negative breast cancer(TNBC)
Some studies have shown that approximately 15% of patients with advanced hormone receptor (HR) positive breast cancer and 1/3 of triple negative breast cancer will develop brain metastasis. At present, there is no unified drug treatment standard for HER2-negative breast cancer brain metastasis (BCBM). The evidence of single traditional chemotherapy drug as the main treatment of brain metastasis is not sufficient. Some exploratory studies on HER2-negative BCBM have shown that the central nervous system objective response rate (CNS-ORR) of anti-angiogenic drugs combined with chemotherapy is around 55%-80%。 Adebrelimab (a humanized PD-L1 monoclonal antibody) specifically blocks the binding of PD-1 and PD-L1, terminates the immunosuppressive signal produced by T cells, and makes T cells re-recognize tumor cells and kill them, thereby inhibiting tumor growth. In China, Adebelizumab has been approved for using in combination with chemotherapy as a first-line treatment for extensive stage small cell lung cancer. Apatinib (a small molecule VEGFR tyrosine kinase inhibitor) mainly plays an anti-angiogenic effect in the treatment of malignant tumors by inhibiting VEGFR. Apatinib has been approved monotherapy for advanced gastric adenocarcinoma or gastroesophageal junction adenocarcinoma that has progressed or relapsed after at least two systematic chemotherapies, advanced liver cancer that has failed or is intolerable after at least first-line systematic treatment, and first-line treatment in patients with unresectable or metastatic hepatocellular carcinoma combined with camrelizumab. Due to the lack of effective drug therapy for HER2-negative BCBM, a variety of treatment combinations are still being explored. We hypothesized that adebrelimab plus apatinib and etoposide is an explorable and effective treatment for HER2- negative BCBM.
This is a multi-site clinical study enrolling 2000 newly diagnosed patients with breast, colorectal, melanoma, non-Hodgkin lymphoma, or non-small cell lung cancer, who are planning to receive one or more systemic cancer directed therapies with chemotherapy and/or (immune checkpoint inhibitors) ICIs.
Background: Triple negative breast cancer (TNBC) is characterized by an aggressive biological behaviour responsible for higher risk of recurrence and shorter median survival. Pembrolizumab, an immune checkpoint inhibitor (ICI) targeting programmed death (PD-1), in association to chemotherapy showed improvement of event-free survival in patients with previously untreated stage II or III TNBC and has been approved in Europe since March 2022 for this indication (KEYNOTE-522). Circadian timing system controls many various biological functions in humans including xenobiotic metabolism and elimination, immune functions, cell cycle event and apoptosis. Thus, chronotherapeutic approaches have shown improved efficacy and tolerability in the treatment of different types of cancer, notably in colorectal cancer. Pronounced circadian rhythms in immune functions are generated by cell-autonomous molecular clocks in T and B lymphocytes, macrophages, neutrophils, and dendritic cells. Recently, first evidence of the effect of timing infusion of immune checkpoint inhibitors on prognosis of patients with cancer has been reported in several retrospective trials. Landre et al.'s meta-analysis of 7 retrospective studies including 1019 patients who had metastatic cancer was presented at the American Society of Clinical Oncology (ASCO) meeting in 2023. An early time-of-day ICI infusions was associated with an increase overall survival (HR: 0.49, [95% CI: 0.36-0.69] p < 0.0001). Objectives: The aim is to analyze immunotherapy infusion timing impact on histological response, toxicity and Event Free-Survival (EFS) in patients with TNBC treated with Neo-Adjuvant Chemotherapy (NAC) associated with pembroluzimab. Measure of histological response is the primary objective determined by Residual Cancer Burden (RCB). Secondary endpoints are Event free Survival (EFS), calculated from the date of diagnosis to invasive local, regional, or metastatic relapse, contralateral breast cancer, or death from any cause), toxicity which is assessed by recording adverse events (CT-CAE v5) occurring from start of treatment to last course. Methods: Data from patients with histologically proven early TNBC treated from July 2021 to May 2023 with the association of Pembrolizumab, Paclitaxel Carboplatine followed with Pembrolizumab Cyclophosphamide Epirubicine (according to KEYNOTE 522 study) will be collected. Dosing times of each Pembrolizumab and chemotherapy infusions given to consecutive patients as a neoadjuvant standard treatment, associated with chemotherapy, for early TNBC are retrieved from hospital records. Adjuvant Pembrolizumab timing intake will be also recorded as EFS is a secondary endpoint. Statistics: First, median clock hour of all infusions of Pembrolizumab will be determined. Then, patients will be dichotomized between "morning' and 'afternoon' groups using 2 cut-offs: 1/ median clock of all infusions of pembrolizumab ('morning group' will include the patients who receive the majority of Pembrolizumab infusions before this median clock hour and 'afternoon group', patients who receive the majority of Pembrolizumab infusions after this median clock hour) and 2/ cut-off optimizing differences of RCB between two groups. Patient's characteristics, toxicities, tumor response and EFS will be compared.
Observational study on prevalence of emerging ESR1 mutations in liquid biopsy in two cohorts of patients with breast cancer (with and without prior therapies in metastatic setting) in comparison with patient's baseline ESR1 mutation status as defined by tissue profiling.
The study compares the quality of sexual life of breast cancer patients under two types of oncoSexology supportive care : personalized supportive care versus on-request. The aim is to improve the quality of sexual life of these patients.
This phase I trial studies the side effects and best dose of vaccine therapy in treating patients with metastatic solid tumors. Vaccines made from antibodies and peptides combined with tumor cells may help the body build an effective immune response to kill tumor cells.
The investigators aim to assess the feasibility and acceptability of conducting a randomised controlled trial (RCT) to test whether receiving ABC (an online-delivered, Cognitive Behavioural Therapy [CBT], group-based, body image programme) alongside a psychoeducational body image booklet provides greater benefits to women treated for breast cancer compared to a receiving a psychoeducational body image booklet alone. Results from this feasibility study will inform the design, management, and future delivery of a definitive randomised controlled trial to assess effectiveness and cost-effectiveness of ABC. Specific objectives are to: - Establish appropriate, inclusive, and acceptable methods of participant recruitment, retention, and management procedures. - Establish the feasibility and acceptability of quantitative data collection, including determining appropriate primary and secondary outcome measures. - Adapt and test a measure of health and social care service use, to inform a future economic evaluation. - Establish intervention adherence and acceptability (of online setting) among participants and ABC facilitators. Participants will be randomised to either the intervention or control arm. The control arm will receive the Macmillan Cancer Support psychoeducational body image booklet. The intervention arm will receive the Macmillan booklet and the ABC programme, a 7-session, CBT group-based programme delivered online. All participants will complete self-report validated outcome measures at weeks 1 (T1; baseline/pre-intervention), 9 (T2; immediate post-intervention), 20 (T3; three-month post intervention), and 32 (T4; six-month post intervention). Following drop-out or completion of all study procedures, a subset of participants will be invited to take part in interviews.
This study examines the impact of phototherapy intervention on anxiety, stress, and body image among breast cancer patients. Participants engaged in a five-week, one-on-one session series, utilizing a pre-post-test design with parallel groups. Quantitative data were collected using the Depression Anxiety Stress Scales (DASS-21) and the Body Image Scale. In addition to quantitative measures, in-depth individual interviews were conducted to gather qualitative data. The combined data were then analysed to assess the effectiveness of the intervention.
This study is designed following the updated Medical Research Council (MRC) Framework for Developing and Evaluating Complex Interventions. The goal of this randomized controlled trial (RCT) is to evaluate the effects, safety, and cost-effectiveness of an evidence-based somatic acupressure (SA) intervention on the fatigue-sleep disturbance-depression symptom cluster and quality of life among breast cancer survivors.
