Filter by:This phase II trial studies how well venetoclax and decitabine work in treating participants with acute myeloid leukemia that has come back or does not respond to treatment, or with high-risk myelodysplastic syndrome that has come back. Drugs used in chemotherapy, such as venetoclax and decitabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading.
This phase I trial studies the side effects and best dose of CD4+ and CD8+ HA-1 T cell receptor (TCR) (HA-1 T TCR) T cells in treating patients with acute leukemia that persists, has come back (recurrent) or does not respond to treatment (refractory) following donor stem cell transplant. T cell receptor is a special protein on T cells that helps them recognize proteins on other cells including leukemia. HA-1 is a protein that is present on the surface of some peoples' blood cells, including leukemia. HA-1 T cell immunotherapy enables genes to be added to the donor cells to make them recognize HA-1 markers on leukemia cells.
Multicenter, randomized, open-label, crossover PK study of ASTX727 versus IV decitabine. Adult subjects who are candidates to receive IV decitabine will be randomized 1:1 to receive the ASTX727 tablet Daily×5 in Cycle 1 followed by IV decitabine 20 mg/m^2 Daily×5 in Cycle 2, or the converse order. After completion of PK studies during the first 2 treatment cycles, subjects will continue to receive treatment with ASTX727 from Cycle 3 onward (in 28-day cycles) until disease progression, unacceptable toxicity, or the subject discontinues treatment or withdraws from the study.
This phase II trial studies how well topotecan hydrochloride and carboplatin with or without veliparib work in treating patients with myeloproliferative disorders that have spread to other places in the body and usually cannot be cured or controlled with treatment (advanced), and acute myeloid leukemia or chronic myelomonocytic leukemia. Drugs used in chemotherapy, such as topotecan hydrochloride and carboplatin, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Veliparib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving topotecan hydrochloride, carboplatin, and veliparib may work better in treating patients with myeloproliferative disorders and acute myeloid leukemia or chronic myelomonocytic leukemia compared to topotecan hydrochloride and carboplatin alone.
Chronic Myelomonocytic Leukemia (CMML) is the most frequent of myelodysplastic/myeloproliferative syndromes, as defined by the WHO classification of myeloid malignancies. The median age at diagnosis is around 70 years with a strong male predominance. CMML is a clonal disease of the bone marrow hematopoietic stem cell mainly characterized by persistent monocytosis (>1x109/L) and the presence of immature dysplastic granulocytes in the peripheral blood of CMML patients. Allogeneic stem cell transplantation (ASCT) remains the only curative option in CMML. However, CMML patients are rarely eligible for this kind of therapy, mainly due to their advanced age. The gold standard treatment of CMML thus remains hydroxyurea, which is usually initiated when the disease becomes proliferative, and demethylating agents, which could be efficient in the most aggressive forms of CMML. Nevertheless, the pathogenesis of CMML remains poorly understood and new therapies are urgently needed for patients in treatment failure. In recent years, a large numbers of gene mutations have been discovered in CMML, none of which are specific of this entity, as they can be encountered with different frequencies in other myeloid neoplasms. These mutated genes encode signaling molecules (NRAS, KRAS, CBL, JAK2, FLT3 and several members of the Notch pathway), epigenetic regulators (TET2, ASXL1, EZH2, IDH1, IDH2,.) and splicing factors (SF3B1, SRSF2, ZRSF2). Mutations in the transcription regulators RUNX1, NPM1 and TP53 have also been reported in CMML. However, the role of these mutations in leukemogenesis is still unclear. CMML is also characterized by defects in monocyte to macrophage differentiation. These defects in monocyte differentiation can be attributed to the presence of immature dysplastic granulocytes that secrete high levels of alpha-defensins HNP1-3 that antagonize the purinergic receptor P2RY6 in CMML patients. These CD14-/CD15+/CD24+ immature granulocytes that belong to the same clone than the leukemic monocytes seem to have immunosuppressive properties ressembling those of the myeloid-derived suppressor cells (MDCS) described in solid tumours. Whether these immature granulocytes contribute to autoimmune manifestations or immunoescape and progression of CMML is a conendrum and remains to be determined. In this context, the proposed project aims at identifying news insights into the pathophysiology of CMML through a better definition of the phenotype and function of monocytes and immature granulocytes that characterize this pathology.
This phase II trial studies how well trametinib works in treating patients with juvenile myelomonocytic leukemia that has come back (relapsed) or does not respond to treatment (refractory). Trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
This trial studies the side effects of recombinant EphB4-HSA fusion protein when given together with azacitidine or decitabine in treating patients with myelodysplastic syndrome, chronic myelomonocytic leukemia, or acute myeloid leukemia that has come back or has not responded to previous treatment with a hypomethylating agent. Recombinant EphB4-HSA fusion protein may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Hypomethylating agents, such as azacitidine and decitabine, slow down genes that promote cell growth and can kill cells that are dividing rapidly. Giving recombinant EphB4-HSA fusion protein together with azacitidine or decitabine may work better in treating patients with myelodysplastic syndrome, chronic myelomonocytic leukemia, or acute myeloid leukemia.
Enrolled subjects will receive histamine dihydrochloride (HDC; Ceplene®) and/or IL-2 (Proleukin®) subcutaneously (s.c.) twice daily (BID) in 3-week periods followed by 3- or 6 week rest periods. All subjects will be assigned to one of three consecutive cohorts, each comprising five patients. Cohort 1 will receive HDC without IL-2 for the first treatment cycle, to enable the assessment of short-term impact of HDC alone on clonal and immunological markers. For all remaining cycles the combination of HDC and IL-2 will be given. Cohort 2 will receive the combination of Ceplene and Proleukin in all cycles. After all patients in cohorts 1 and 2 have completed 4 treatment cycles, immunological and clinical response and toxicity will be evaluated. On the basis of the results for the first 4 cycles of cohorts 1 and 2, a third cohort of 5 patients will be enrolled receiving either the combination of HDC/IL-2 or HDC alone. In case of a beneficial response* after 4 cycles, treatment may be continued to a total of 10 cycles. Treatment cycles 5-10 will comprise 3 weeks of treatment and 6-week rest periods. IL-2 will be administered s.c., 1 µg/kg (=16400 IU/kg) body weight twice daily (BID) during treatment periods. Ceplene® will be administered s.c. 0.5 mg BID after IL-2. The patient or a family member/significant other will be instructed to administer injections of both study drugs to allow safe treatment at home.
This phase I/II trial studies the side effects and best dose of guadecitabine when given together with atezolizumab and to see how well they work in treating patients with myelodysplastic syndrome or chronic myelomonocytic leukemia that has spread to other places in the body and has come back or does not respond to treatment. Guadecitabine may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as atezolizumab, may interfere with the ability of cancer cells to grow and spread. Giving guadecitabine and atezolizumab may work better in treating patients with myelodysplastic syndrome or chronic myelomonocytic leukemia.
For the first 28 day cycle, all patients will be treated with single agent pacritinib at 200 mg twice daily. The investigators chose this starting dose based on the previous three phase I studies of pacritinib as a single agent which showed that the maximum tolerated dose (MTD) to be 500 mg, and subsequently, the dose of 400 mg daily was recommended for the phase II studies. Recently, the results of the phase III PERSIST-1 trial comparing pacritinib to best available therapy (BAT) in patients with MF was reported at the 2015 American Society of Clinical Oncology (ASCO) annual meeting. Pacritinib was found to be significantly more effective than BAT at reducing spleen volume at 24 weeks of therapy and improving constitutional symptoms. Low dose decitabine has demonstrated depletion of DNMT1 in normal hematopoietic stem cells (HSC) without cytotoxicity and subcutaneous (SC) instead of intravenous (IV) administration may avoid high peak levels that can cause apoptosis. Furthermore, the low toxicity associated with low dose decitabine would allow for more frequent (1 to 3 times weekly) administration of the drug which would catch more cells in S-phase via greater exposure time. Based on these findings, a starting dose of decitabine 5 mg/m2 SC twice weekly should be well tolerated and effective in patients with MF and MPN/MDS syndromes when combined with pacritinib 400 mg daily.
