Study of Fuquinitinib Combined With Capecitabine First-line Maintenance in the Treatment of Metastatic Colorectal Cancer

ABSTRACT: This is a single-arm, single-center, prospective phase I/II study that received standard first-line chemotherapy (FOLFOX,FOLFIRI,XELOX, FOLFOXIRI± targeted therapy). If the first-line chemotherapy regimen is a 2-week regimen, patients need to undergo ≥8 cycles of standard chemotherapy. If the first-line chemotherapy regimen is a 3-week regimen, maintenance therapy is required for patients with unresectable advanced metastatic colorectal cancer who have reached CR,PR,SD (RECIST 1.1) after standard chemotherapy after ≥4 cycles. The eligible patients were screened for maintenance treatment. Maintenance therapy research is divided into the following two phases: Phase IIB fuquinitinib combined capecitabine dose exploration trial (n=6-9) : Phase II: Dose extension trial (n=47) : 47 patients were continued to be enrolled in the dose extension phase trial according to the recommended dose of fuquinitinib combined with capecitabine established in phase iB, and were treated until toxicity became intolerable or disease progression.

Creatine in Huntington's Disease (HD) (CREST-E)

Project description:<p> This is a multi-center, randomized, double-blind, placebo-controlled trial of creatine monohydrate involving 553 ambulatory subjects with HD who are not requiring skilled care or institutionalization. Eligible subjects were randomized to receive up to 40 grams daily of creatine monohydrate or matching placebo. Randomization will be followed by a Titration Phase, a Maintenance Phase, an Optional Extended Maintenance Phase, and Washout. During the Titration Phase, which may last up to six months, study drug will be initially escalated in 5-gram increments starting at 5 g/day until the 40 g/day target dose is reached. Should subjects be unable to reach or stay at the maximum dose during the Titration Phase, they will remain on the highest tolerated dose (HTD) for which they have no significant side effects. During the Maintenance Phase, subjects will be followed prospectively and systematically. Subjects completing 36 months of follow-up on study drug will be eligible to continue in the study for an additional twelve months of follow-up in the Extended Maintenance Phase. The primary measure of efficacy is the annualized rate of change in TFC. The primary hypothesis of the study is that chronic treatment of early-stage HD subjects with creatine monohydrate will slow the progressive functional decline of HD. </p>

Chemotherapy negatively impacts the tumor immune microenvironment in NSCLC: An analysis of pre- and post-treatment biopsies in the multi-center SAKK19/09 study

Project description:Background: Over the past few years, immune checkpoint inhibitors have changed the therapeutic landscape of non-small-cell lung cancer (NSCLC). Response to immune checkpoint inhibitors correlates with a pre-existing anti-tumoral immune response. Checkpoint inhibitors have been introduced as second line therapy and are only very recently used as monotherapy or in combination with chemotherapy as first line treatment of NSCLC. However, the effect of conventional first line platinum-based chemotherapy on the immune infiltrate in the tumor is largely unknown. Methods: We measured the gene expression of a custom set of 201 cancer- and immune-related genes in 100 NSCLC tumor biopsies collected before chemotherapy and 33 re-biopsies after platinum-based chemotherapy at the time point of progression. For 29 patients matched pre- and post-chemotherapy samples could be evaluated. Results: We identified a cluster of 47 co-expressed immune genes, including PDCD1 (PD1) and CD274 (PD-L1), along with three other co-expression clusters. Chemotherapy decreased the average gene expression of the immune cluster while no effect was observed on the other three cluster. Within this immune cluster, CTLA4, LAG3, TNFRSF18, CD80 and FOXP3 were found to be significantly decreased in patient-matched samples after chemotherapy. Conclusion: Our results suggest that conventional platinum-based chemotherapy negatively impacts the immune microenvironment at the time point of secondary progression.

In-depth proteomic analysis for discovery of response prediction markers in breast cancer chemotherpy using needle biopsy FFPE tissue

Project description:Breast cancer is the most frequently diagnosed female cancer accounting for 23 % of the total cases and the second leading cause of cancer mortality in the world, particularly in western countries. Since GEPARDUO trial reported the therapeutic benefit of combined doxorubicin and cyclophosphamide regimen in sequential administration with docetaxel, the combination regimen has become a standard therapeutic strategy in neoadjuvant systemic therapy for patients with operable breast cancers regardless of an intrinsic subtype. Although approximately 70% of entire patients are currently receiving the chemotherapy regimen, pathologic complete response (pCR) rate is still low, ranging from 23% to 32.7% due to the high heterogeneity of breast cancers. Therefore, the need for a marker predictive of response to a particular cytotoxic regimen, especially before neoadjuvant chemotherapy, is becoming all the more necessary to optimize therapeutic efficacy and to avoid unnecessary complications caused by systemic therapy. In the study, here we generated the first high-coverage proteomic data for needle biopsy FFPE sample being characterized with identical clinical conditions including chemotherapeutic regimens and the stage classification.

A novel and highly effective mitochondrial uncoupling drug (MB1-47) in T-cell acute lymphoblastic leukemia

Project description:T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive hematologic malignancy. Despite recent advances in treatments with intensified chemotherapy regimens, relapse rates and associated morbidities remain high. In this context, metabolic dependencies have emerged as a druggable opportunity for the treatment of leukemia. Here, we tested the antileukemic effects of MB1-47, a newly developed mitochondrial uncoupling compound. MB1-47 treatment in T-ALL cells robustly inhibited cell proliferation via both cytostatic and cytotoxic effects as a result of compromised mitochondrial energy and macromolecule depletion, which severely impair nucleotide biosynthesis. Mechanistically, acute treatment with MB1-47 in primary leukemias promoted AMPK activation and downregulation of mTOR signaling, stalling anabolic pathways that support leukemic cell survival. Indeed, MB1-47 treatment in mice harboring murine NOTCH1-induced leukemias or human T-ALL PDXs led to a potent antileukemic effect with 2-fold extension in survival without overlapping toxicities. Overall, our findings demonstrate a critical role for mitochondrial oxidative phosphorylation in T-ALL and uncover MB1-47-driven mitochondrial uncoupling as a novel therapeutic strategy for the treatment of this disease.

Protective effects on melphalan-induced mouse intestinal injury treated by Human Umbilical Cord-derived Mesenchymal Stem Cells

Project description:Autologous peripheral hematopoietic stem cell transplantation (autoHSCT) is one front-line therapy with high-dose melphalan for multiple myeloma (MM). Patients with MM who receive conditioning regimen with melphalan usually suffer from severe gastrointestinal symptoms, as one of nonhematological toxicities. Aim: It is an urgent demand to develop an effective methods to repair the intestinal injuries in patients with MM receiving conditioning regimen with high-dose melphalan for autoHSCT. Therefore, the protective effects of Human umbilical cord derived-mesenchymal stem cells (hucMSCs) is investigated after infusion into mouse model with melphalan-induce gastrointestinal injuries.

Transcription profiling of advanced human breast cancers treated with a dose-intense epirubicin /cyclophosphamide regimen followed by mastectomy

Project description:A "Cartes d'Identite des Tumeurs" (CIT) project from the french Ligue Nationale Contre le Cancer (http://cit.ligue-cancer.net). 37 samples hybridized on Affymetrix HG-U133A arrays. Analysis of advanced breast cancers treated with a dose-intense epirubicin /cyclophosphamide regimen followed by mastectomy; Validation of TP53-related genes in breast and bladder cancers. We found that a complete response to chemotherapy was only observed in TP53 mutant tumours. We further show that, among TP53 mutant tumours, high basalcytokeratin and low ESR1 expression levels were associated with complete responses. These observations pave the way to molecular tailoring of chemotherapy in breast cancer.

Gene expression profiles of patients with multiple myeloma who have been treated previously

Project description:This Series represents the gene expression profiles of patients with multiple myeloma who have been treated previously. In brief, Total Therapy 6 (TT6) is an open label phase 2 protocol for patients with symptomatic multiple myeloma, who had been treated with more than one cycle of prior therapy excluding autologous hematopoietic stem cell transplant. This protocol was approved by the institutional review board on March 25, 2009 (IRB#108053). The TT6 treatment regimen consists of induction therapy with Melphalan/Bortezomib/Thalidomide/Dexamethasone/Cisplatin/Doxorubicin/Cyclophosphamide/Etoposide (M-VTD-PACE) followed by a high dose M-VTD-PACE based tandem transplant. Maintenance therapy consists of Bortezomib/Lenalidomide/Dexamethasone alternating with Borteomib/Melphalan/Dexamethasone every months for 3 years. We analyzed CD138+ selected cells of previously treated MM patients by microarray.
