Active clinical trials for "Myelodysplastic Syndromes"

This randomized phase II trial studies how well WEE1 inhibitor AZD1775 with or without cytarabine works in treating patients with acute myeloid leukemia or myelodysplastic syndrome that has spread to other places in the body and usually cannot be cured or controlled with treatment. WEE1 inhibitor AZD1775 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as cytarabine, 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. It is not yet known whether giving WEE1 inhibitor AZD1775 works better with or without cytarabine in treating patients with advanced acute myeloid leukemia or myelodysplastic syndrome.

This is the first study of the safety of increasing dose levels of AEB1102 in patients with Relapsed or Refractory Acute Myeloid Leukemia or Myelodysplastic Syndrome. The study will also evaluate the amounts of AEB1102 in blood, the effects of AEB1102 on blood amino acid levels and the antitumor effects of AEB1102.

The purpose of this study is to use genomic information from individual patients to create simulation avatars that will be used to predict novel drug combinations with therapeutic potential.

This is a multicenter, open label, Phase 1 dose-escalation study of DSP-7888 Dosing Emulsion administered to adult patients with advanced malignancies. Patients will be administered escalating doses of DSP-7888 Dosing Emulsion intradermally or subcutaneously in accordance with the following regimen: once weekly for four weeks during the Induction Phase, once every 7 to 14 days for 6 weeks during the Consolidation Phase, and once every 14 to 28 days until a discontinuation criterion is met during the Maintenance Phase. Once RP2D is determined from either the intradermal or subcutaneous group, an additional 40 patients evaluable for response may be enrolled as an expansion cohort at this dose and route of administration to confirm safety and tolerability. Separate from the dose-ascending cohort and RP2D expansion cohort described previously, and once the intradermal dose-ascending cohort is completed, up to 20 MDS patients who are refractory to treatment with hypomethylating agents (HMAs) will be enrolled into an MDS expansion cohort. Of these 20 MDS patients, one-half will receive DSP-7888 at 10.5 mg according to the modified schedule employed in Phase 1 (every week for 4 weeks, every 2 weeks until Week 24, and then every 4 weeks; [MDS Cohort 1]). The other half of the MDS patients will receive DSP-7888 at 10.5 mg in an alternative dosing schedule where DSP-7888 is administered every 2 weeks until Week 24, after which it will be administered every 4 weeks (MDS Cohort 2).

This study is conducted to evaluate the feasibility and efficacy of post-transplantation cyclophosphamide with myeloablative or reduced-intensity conditioning regimen for allogeneic hematopoietic cell transplantation (HCT) in patients with myelodysplastic syndrome (MDS).

The purpose of this study is to assess the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and preliminary antitumor activity of AZD4573 in subjects with relapsed or refractory haematological malignancies.

This phase II trial studies how well tacrolimus, bortezomib, and anti-thymocyte globulin (thymoglobulin) work in preventing low toxicity graft versus host disease (GVHD) in patients with blood cancer who are undergoing donor stem cell transplant. Tacrolimus and anti-thymocyte globulin may reduce the risk of the recipient's body rejecting the transplant by suppressing the recipient's immune system. Giving bortezomib after the transplant may help prevent GVHD by stopping the donor's cells from attacking the recipient. Giving tacrolimus, bortezomib, and anti-thymocyte globulin may be a better way to prevent low toxicity GVHD in patients with blood cancer undergoing donor stem cell transplant.

This study evaluates whether vitamin C improves responses to epigenetic therapy with DNMTis. Half of the patients will receive vitamin C and DNMTi while the other half will receive placebo and DNMTi.

The dose-confirming part of this study, comprising at least 10 patients is designed as a single center, prospective, single arm, open label in patients who have failed or are unresponsive to Azacitidine (AZA) or Decitabine (they may also have additionally failed an Erythropoiesis Stimulating Agent (ESA) followed by a dose expansion part with at least 44 patients; the objective of the whole study being to assess the safety, efficacy, pharmacokinetics and pharmacodynamics of intravenously infused multiple doses of OPN-305 in low and intermediate-1 risk myelodysplastic syndrome (second and third line Lower risk MDS).

Allogeneic hematopoetic stem cell transplantation (SCT) is frequently complicated by life threatening viral reactivation. Conventional antiviral therapy is suboptimal for cytomegalovirus (CMV), adenovirus (AdV) and Epstein-Barr virus (EBV) and nonexistent for BK virus (BKV). An alternative approach to prevent viral reactivation is to infuse virus-specific cytotoxic T cells (CTL) prepared from the donor early after SCT. Such multivirus-specific CTL cells (MVST) have been successfully used in a number of centers to prevent or treat CMV, Ad and EBV. Activity of BKV-reactive cells has not been studied. Multi virus-specific T cells (MVST) are donor lymphocytes that are highly enriched for viral antigens and expanded in vitro before infusion into the transplant recipient. Viral reactivation is a particular problem inT cell depleted SCT. Median time to CMV reactivation is estimated as 28 days post T-depleted transplant, but infusion of MVST within the immediate post-SCT period has not been previously studied. This protocol will be the first of a planned series of cellular therapies to be layered on our existing T lymphocyte depleted transplant platform protocol 13-H-0144. The aim of this study is to determine the safety and efficacy of very early infusion of MVST directed against the four most common viruses causing complications after T-depleted SCT. GMP-grade allogeneic MVST from the stem cell donor will be generated using monocyte-derived donor dendritic cells (DCs) pulsed with overlapping peptide libraries of immunodominant antigens from CMV, EBV, Ad, and BKV and expanded in IL-7 and IL-15 followed by IL-2 for 10-14 days. A fraction of the routine donor leukapheresis for lymphocytes obtained prior to stem cell mobilization will be used to generate the MVST cells. MVST passing release criteria will be cryopreserved ready for infusion post SCT. Eligible subjects on NHLBI protocol 13-H-0144 will receive a single early infusion of MVST within 30 days (target day +14, range 0-30 days) post SCT. Phase I safety monitoring will continue for 6 weeks. Viral reactivation (CMV, EBV, Ad, BK) will be monitored by PCR by serial blood sampling. The only antiviral prophylaxis given will be acyclovir to prevent herpes simplex and varicella zoster reactivation. Subjects with rising PCR exceeding threshold for treatment, or those with clinically overt viral disease will receive conventional antiviral treatment. Patients developing acute GVHD will receive standard treatment with systemic steroids. These patients are eligible for reinfusion of MVST when steroids are tapered. The clinical trial is designed as a single institution, open label, non-randomized Phase I/II trial of MVST in transplant recipients, designed as 3-cohort dose escalation Phase I followed by a 20 subject extension Phase II at the maximum tolerated dose of cells. Safety will be monitored continuously for a period of 6 weeks post T cell transfer. The primary safety endpoint will be the occurrence of dose limiting toxicity, defined as the occurrence of Grade IV GVHD or any other SAE that is deemed to be at least probably or definitely related to the investigational product. The primary efficacy endpoint for the phase II will be the proportion of CMV reactivation requiring treatment at day 100 post transplant. Secondary endpoints are technical feasibility of MSVT manufacture, patterns of virus reactivation by PCR, and clinical disease from EBV, Ad, BK, day 100 non-relapse mortality.
