Active clinical trials for "Neoplasm, Residual"

Short-term relapse and poor survival are prevalent in patients with pancreatic adenocarcinoma (PAAD) after surgeries. Despite the importance of adjuvant treatments for resected PAAD patients, there is currently no suitable biomarker to identify those individuals with high risk of recurrence and inform therapeutic decision making. In this study, we aim to examine whether postoperative circulating tumor DNA (ctDNA) could be used as a biomarker for early detection of minimal residual disease (MRD) and predicting relapse in resected PAAD through high-depth targeted next-generation sequencing.

This phase II trial studies how well autologous stem cell transplant works in treating patients with favorable or intermediate risk, minimal residual disease (MRD)-negative, acute myeloid leukemia. Giving chemotherapy before a peripheral blood stem cell transplant helps kill any cancer cells that are in the body. After treatment, stem cells are collected from the patient's blood and stored. Higher dose chemotherapy is then given to prepare the bone marrow for the stem cell transplant. The stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy.

This is a non-randomized, open-label, multi-site study to collect safety and efficacy data on an intraoperative imaging system, the LUM Imaging System (LUM015 imaging agent in conjunction with the LUM imaging device), in identifying residual cancer in the tumor bed of female breast cancer patients. During the study, study physicians and clinical staff will complete hands-on training in anticipation of the upcoming pivotal study. Site-specific or user-specific issues related to the use of the device will be identified and addressed. Additionally, the data collected in the study will be used to continue training the tumor detection algorithm of the device. In this study, patients will be injected with LUM015 prior to surgery. The study physicians will perform lumpectomy procedures according to his or her institution's standard of care practice. After the main specimen removal is completed, the study physician will use the LUM Imaging Device to image the tumor bed. Therapeutic shaves will be removed based on the recommendation of the LUM Imaging System. Patients will be followed until their first standard of care post-operative follow-up visit.

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.

Allogeneic hematopoietic cell transplantation (Allo-HSCT) is an effective therapy for acute leukemia, but relapse is the most common problem affecting long-term survivors of allo-HSCT. Therapy options for relapse include stopping immune suppression, re-induction of chemotherapy, donor lymphocyte infusion (DLI) or combination therapy. In this prospective randomized controlled study, the safety and efficacy of hypomethylating agents (HMA) + DLI and DLI preemptive therapy based on minimal residual disease in acute leukemia undergoing allo-HSCT are evaluated.

This trial will evaluate the effectiveness and safety of haploid donor-derived in vitro activated natural killer(NK) cells infusion for Treating acute myeloid leukemia Patients With minimal residual disease.

The main purpose of this study is to explore the efficacy of CD19-targeted CAR-T cell therapy for minimal residual disease (MRD) in B-cell Malignancies after autologous stem cell transplantation.

The purpose of this study is to see if the investigator can help the immune system to work against myeloma through the use/administration of a peptide vaccine (immunotherapy agent) directed against the Wilms Tumor 1 (WT1) protein called galinpepimut-S (or GPS, for brief). Because cancer is produced by the patient's own body, the immune system does not easily recognize and fight cancer cells. The immune system needs to be "trained" to do this; the latter goal is accomplished by using a vaccine consisting of selected fragments of the target antigen, in this case, WT1. This disease has been selected for this study because the WT1 protein is often present in myeloma cells. WT1 is a gene that is involved in the normal development of kidneys and other organs. When the WT1 gene becomes abnormal, it can make proteins involved in the development of cancer, i.e., can acquire the properties of a true "oncogene". This study will determine whether the vaccine against the WT1 antigen (present in malignant plasmacytes) can cause an immune response which is safe, but also able to keep the myeloma from either coming back or progressing.

Objectives To demonstrate that measurable residual disease assessed by multiparameter flow cytometry during intensive treatment is a surrogate for overall survival and thus an early read-out for drug efficacy Study design Surrogate endpoint trial to establish that measurable residual disease assessed by multiparameter flow cytometry during intensive treatment is a surrogate for overall survival

This phase 2 study is designed to evaluate the safety, tolerability and efficacy of allogeneic donor lymphocyte infusions (DLI) combined with the bispecific T cell engager blinatumomab in B-precursor ALL patients who have mixed chimerism (MC) or are MRD-positive after allogeneic SCT and are refractory to at least one MRD- or MC-targeted therapy (i.e. blinatumomab, DLI, tyrosine kinase inhibitors or other agents).
