Filter by:So far, MRD assessment by liquid biopsy (ctDNA) has not been used to predict postoperative treatment efficacy and recurrence risk of GIST patients because of special disease characteristics and technological limitations. Therefore, we conducted this prospective multi-center, single-arm observational study to collect 45 operable patients with locally advanced, suspected high-risk GIST. NGS genetic testing platform is used to detect tumour tissues and peripheral ctDNA will also be dectected. we try to explore the correlation between PFS/OS and MRD in high-risk GIST patients by analyzing the relationship between dynamic changes in ctDNA mutation spectrum and postoperative adjuvant therapy efficacy, and to evaluate MRD-based genomic characteristics to guide further treatment.
Although studies are ongoing to evaluate the efficiency and safety of venetoclax-based therapy, alone or in combination with hypomethylation agent or low-dose cytarabine, in relapsed/refractory acute myeloid leukemia, data are scarce and heterogenous. In this study, the investigators aimed to assess safety and response to a new venetoclax-based triple-drug combination regimen (venetoclax + hypomethylation agent + low-dose cytarabine) in acute myeloid leukemia patients who had relapsed/refractory disease or positive minimal residual disease.
Various drugs have been added to different treatment regimens in order to improve the response rate in patients with Acute Lymphoblastic Leukemia, however, it has been shown that adding Bortezomib to the relapsing regimen improves the proportion of second complete remissions without increasing chemotherapy toxicity. Therefore, proteasome inhibitors can drastically modify the prognosis of patients, since their synergy with drugs such as steroids has positioned them as an attractive strategy.
Chronic lymphocytic leukaemia (CLL) is the most common adult blood cancer in the United Kingdom. CLL means that many cancer cells appear in the blood, bone marrow and other tissues, for example, the spleen where some blood cells reside. Most patients with CLL have been diagnosed by chance, have no symptoms as a result of CLL, and do not need urgent treatment. However, when the cancer cells build up, people experience symptoms of CLL, and treatment is required. One of the current treatments for CLL is chemo-immunotherapy, that targets and kills cancer cells in the blood. However, this treatment does not kill all cancer cells. Some cancer cells survive by 'hiding' in the bone marrow and tissues, like the spleen, where the treatment cannot get to, this is called minimal residual disease (MRD). MRD eventually builds up and patients experience symptoms of CLL again. New approaches to detect and treat MRD are needed. Research has shown, that the number of blood cells, increases after exercise and that many of these blood cells come from the bone marrow and other tissues. This study will investigate if exercise can move CLL cancer cells that are 'hiding' in the bone marrow and other tissues into the blood, thus improving the detection of MRD. By moving cancer cells into blood, the investigators also think this will improve the way chemo-immunotherapy works. In this study, the investigators will investigate the number of cancer and natural killer (NK) cells in the blood after exercise, in three different groups of people with CLL: before treatment; during treatment; and after treatment has finished.
Purpose: The purpose of this trial is to investigate whether a digital array assay can detect trace amounts of residual leukemia and predict relapse in acute myeloid leukemia (AML) patients in remission who have undergone allogeneic stem cell transplantation (SCT) at the North Carolina Cancer Hospital (NCCH). Participants: Adult patients (18 years of age or older) with diagnosed AML who are going to undergo stem cell transplant (SCT). Procedures (methods): A total of 10 eligible subjects will be treated per standard of care with SCT. Peripheral blood and bone marrow aspirate (10 mL each) for digital array assay analysis will be collected along with routine lab draws and bone marrow biopsy procedures prior to SCT. Beginning 1 month after SCT peripheral blood (10 ml) will be collected to assess MRD by digital array assay analysis on a monthly basis for up to 6 months. In addition, bone marrow aspirate will be collected at approximately Month 3 and 6 following SCT for assay analysis. Patient medical records will be reviewed 6 and 12 months after completing their last MRD follow up assessment to confirm survival status, remission status, and gather information related to relapse.
This is a Phase 1 study to assess the safety and efficacy of ELI-002 immunotherapy (a lipid-conjugated immune-stimulatory oligonucleotide [Amph-CpG-7909] plus a mixture of lipid-conjugated peptide-based antigens [Amph-Peptides]) as adjuvant treatment of minimal residual disease (MRD) in subjects with KRAS/neuroblastoma ras viral oncogene homolog (NRAS) mutated PDAC or other solid tumors.
An add-on phase II trial within the ALL SCTped 2012 FORUM with the primary objective to determine whether the use of Blincyto in paediatric patients with B-lineage ALL and pre- and/or post-transplant MRD could induce MRD-negativity in patients who were MRD-positive before and/or after allogeneic HSCT. The study protocol entitled "A Phase II Study of Blincyto (Blinatumomab) in Children with CD19+ B-lineage Acute Lymphoblastic Leukemia (ALL) and Minimal Residual Disease (MRD)-Positivity before or following first Allogeneic Hematopoetic Stem Cell Transplantation (HSCT) in complete remission (CR1, CR2, CR3)" was included in the ALL SCTped 2012 FORUM Protocol Appendix 1b. According to protocol, 15 mcg/m2/day of Blincyto is given in continuous intravenous infusion over a 28-day cycle. Starting day for patients who are MRD-positive before HSCT is between day +60 and day +100 and for patients who become MRD-positive post HSCT it is between day +60 and day +360 post HSCT. Patients are evaluated for response at day +28 (+4 days) (bone marrow morphology and MRD analysis - defined by PCR/FLOW-techniques) after start of Blincyto-treatment at the end of first Blincyto infusion and at regular post-TX-checks (according to FORUM: days +28, +60, +100, +180 and +360 after HSCT). The protocol was approved in 10 countries (Austria, Belgium, Czech Republic, Denmark, France, Italy, Norway, Poland, Slovakia and Spain) participating ALL SCTped 2012 FORUM study. Overall, 3 patients were treated with Blincyto (2 in Oslo and 1 in Copenhagen). However, the Investigator Initiated Research Agreement was terminated by Amgen on 26 April 2022, leading to an early termination of the study, which was approved with the last protocol amendment.
MDS/AML with MRD and impending relapse after allogeneic stem cell transplantation and/or conventional chemotherapy
This is a single-arm, open-label, multi-center phase I study using blinatumomab for pediatric B-cell acute lymphoblastic leukemia patients with positive of minimal residual disease. 1 Cycle of blinatumomab treatment followed by hematopoietic stem cell transplantation. Blinatumomab has approved to treat adults and children with B-cell precursor ALL who are in remission but still have MRD. However, data on the effects and safety of blinatumomab in children with B-precursor ALL with MRD positive are insufficient.
To the best of our knowledge, BELUGA will be the first prospective trial investigating the usefulness of deep learning-based hematologic diagnostic algorithms. Taking advantage of an unprecedented collection of diagnostic samples consisting of flow cytometry datapoints and digitalized blood-smears, categorization of yet undiagnosed patient samples will prospectively be compared to current state-of-the-art diagnosis at the Munich Leukemia Laboratory (hereafter MLL). In total, a collection of 25,000 digitalized blood smears and 25,000 flow cytometry datapoints will be prospectively used to train an AI-based deep neuronal network for correct categorization. Subsequently, the superiority will be challenged for the primary endpoints: sensitivity and specificity of diagnosis, most probable diagnosis, and time to diagnose. The secondary endpoints will compare the consequences regarding further diagnostic work-up and, thus, clinical decision making between routine diagnosis and AI guided diagnostics. BELUGA will set the stage for the introduction of AI-based hematologic diagnostics in a real-world setting.
