Active clinical trials for "Neoplasm, Residual"

This randomized phase II trial studies how well treosulfan and fludarabine phosphate, with or without total body irradiation before donor stem cell transplant works in treating patients with myelodysplastic syndrome or acute myeloid leukemia. Giving chemotherapy, such as treosulfan and fludarabine phosphate, and total-body irradiation before a donor stem cell transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving tacrolimus before and mycophenolate mofetil after the transplant may stop this from happening.

The purpose of this study is to evaluate safety of the triple COG schema with the monoclonal antibody Dinutuximab + cytokines (GM-CSF and IL2) and isotretinoin (13-cis-retinoic acid, or RA) in patients with high-risk neuroblastoma.

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) in early first complete remission improves the long-term outcomes for Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL). Relapse remains a major cause of treatment failure even after allo-HSCT. The prevention of relapse is essential for improving the outcome of Ph+ ALL. Our previous clinical trial (ID: NCT01883219) demonstrated that pre-emptive tyrosine kinase inhibitor (TKIs) administration based on minimal residual disease (MRD) and BCR-ABL mutation after allo-HSCT might reduce the incidence of relapses and improve survival for patients with Ph+ ALL. Moreover, our result suggested that Ph+ ALL with MRD positive pre-transplants had the higher rate of molecular biology relapse. In this study, we will evaluate the safety and efficacy of prophylactic TKI therapy post-transplants on Ph+ ALL undergoing allo-HSCT with MRD positive pre-transplants.

A phase II trial of continuous intravenous infusion of Blincyto given 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 will be 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 dose of Blincyto used in this trial will be 15 mcg/m2/day for 28 days

This phase II trial studies how well tislelizumab combined with DNA hypomethylation agent +/- CAG regimen (cytarabine, idarubicin / Aclarithromycin, rhG-CSF/ PEG-rhG-CSF) work in treating patients with high-risk acute myeloid leukemia (AML) or AML patients older than 60 years of age who are unfit for standard-dose chemotherapy. The expressions of PD-1 and PD-L1 are increased in AML cells. However, blocking the immune checkpoint alone has limited efficacy as a single agent in highly proliferative leukemia cells. During the recovery period after cytotoxic chemotherapy, the activation of PD-1/PD-L1 pathway may be increased and DNA hypomethylation agents can also up-regulate PD-1, PD-L1 and PD-L2 in AML patients. The up-regulation and activation of above immune checkpoint molecules are related to chemotherapy resistance. Therefore, adding chemotherapy and epigenetic regulation agents to Immune checkpoint blockade therapy may work better through overcoming drug resistance in AML treatment.

Triple-negative breast cancer (TNBC) refers to any breast cancer that does not express estrogen receptor (ER), progesterone receptor (PR) or Her2/neu. Its incidence is approximately 180,000 cases per year. TNBC are known to be more aggressive with poor prognosis specially when no pathologic complete response (pCR) is achieved after neoadjuvant chemotherapy, with a higher risk of recurrence and a poor survival once that recurrence occurs. On the other hand, there is not a specific adjuvant or neoadjuvant treatment for these patients. Since autologous hematopoietic stem cell transplantation (HSCT) allows the usage of higher doses of chemotherapy, which results in higher cellular destruction with a decrease of hematological toxicity, it is proposed that this procedure is able to improve prognosis in TNBC patients with no pathologic complete response after neoadjuvant chemotherapy.

The purpose of this study is to evaluate the efficacy of tyrosine kinase inhibitor(TKI) therapy based on molecular monitoring of BCR/ABL levels in Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL)undergoing allogeneic hematopoietic stem cell transplantation(allo-HSCT).

This study aimed to evaluate the efficacy of interferon α among patients undergone unmanipulated blood and marrow transplantation following day 60 post-transplantation who were minimal residual disease positive after transplantation. Hematopoietic stem cell transplantation (HSCT) is an effective treatment option for acute leukemia and many other hematological malignancies. However, post-transplant relapse can occur in some patients, and the prognosis of these patients is usually very poor.The persistence or recurrence of minimal residual disease (MRD) in the post-transplant period is an independent risk factor of relapse. Therefore, MRD monitoring can be used to screen patients with a high risk of relapse to provide timely intervention and prevent post-transplant relapse.Interferon α-2b exerts a relatively strong immunomodulatory effect. It can kill acute leukemia (AL) cells by regulating T-cell and/or natural killer cell functions.Consequently, interferon α-2b may have potential therapeutic value for AL patients with MRD-positive after transplantation. The study hypothesis: Prevention of relapse using interferon α-2b following hematopoietic stem cell transplantation in patients with standard risk acute leukemia can reduce relapse rate.

Purpose: The purpose of this trial is to investigate whether a microfluidics 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) or Induction and Consolidation Chemotherapy (ICC) at the North Carolina Cancer Hospital (NCCH). Procedures (methods): A total of 40 eligible subjects will be treated per standard of care with either SCT or induction and consolidation chemotherapy (ICC) based on the appropriate AML treatment paradigm for their disease. Peripheral blood (10 ml) for microfluidic chip analysis and possible Immune Monitoring Core Facility analysis will be collected along with routine lab draws prior to SCT. Patients in remission after SCT or those with confirmed remission by bone marrow biopsy after induction chemotherapy will be followed for 1 year; and peripheral blood (20 ml) will be collected to assess MRD by standard methods or by microfluidic chip analysis on a monthly basis. In addition, bone marrow biopsies will be performed at the end of consolidation (typically 5 months from remission), and at 1-year post remission in non-transplant patients. In transplanted patients, bone marrow biopsies will be collected at + 30 days, + 90 days, +180 days, and +360 days after SCT.

RATIONALE: Testing for minimal residual disease in blood samples from patients with acute lymphoblastic leukemia may help doctors plan better treatment. PURPOSE: This research trial studies a genetic test in detecting minimal residual disease in samples from younger patients registered on COG-AALL08B1 trial.
