Thiotepa-based Conditioning Regimen With De-escalated Post-graft Cyclophosphamide for Allogeneic Stem Cell Transplantation in Hematologic Malignancies

This phase 1 trial will investigate the safety and effectiveness of Thiotepa, Busulfan, and Fludarabine (TBF) conditioning regimen with post-transplant cyclophosphamide (PTCy) in HLA-matched related or unrelated donor allogeneic stem cell transplantation (alloSCT).

Study of Flonoltinib Maleate Tablets in the Treatment of Proliferative Bone Marrow Tumors

Flonoltinib Maleate (FM) targets Janus kinase 2 (JAK2) and FMS-like tyrosine kinase 3 (FLT3). FM is a dual target inhibitor of JAK2/FLT3.FM has the activity of inhibiting JAK2 signaling pathway, and pharmacodynamics evaluation also confirmed that FM has a good therapeutic effect on the primary splenomegaly model of mice induced by JAK2V617 mutation.Therefore, FM has the potential to treat bone marrow proliferative tumors.The drug is intended to be used in patients with MPN, mainly including medium-risk or high-risk myelofibrosis (FM) (including primary myelofibrosis (PMF), post-polycythemia vera myelofibrosis (PostPV-MF) and post-primary thrombocythemia myelofibrosis (postET-MF)), Polycythemia vera (PV) and essential thrombocythemia (ET) were the primary causes of thrombocythemia and thrombocythemia. FM has high inhibitory activity against JAK family and FLT3 kinase, suggesting that FM may have a certain therapeutic effect on AML disease.The IC50 of JAK2 kinase inhibition by FM was as low as 0.8 nM, while the IC50 of JAK1, JAK3 and Tyk2 kinase inhibition was 690 nM, 557 nM and 65nM, respectively. The selectivity of JAK2 kinase inhibition by FM was 862.5, 696.3 and 81.3 times, respectively. Therefore, FM showed highly selective inhibition of JAK2 kinase.The IC50 for FLT3 kinase was 15 nM. FM has better inhibitory activity against JAK2 kinase than the listed Ruxolitinib and Fedratinib, and has better selectivity against JAK family.In order to determine whether FM has targets other than JAK2 and Flt3 kinases, we tested FM's inhibitory activity against 100 human kinases that are highly associated with tumors, including some common drug-resistant mutant kinases.The results showed that, except for CDK4/6, LCK and LN, FM had no obvious inhibitory activity against the screened kinases at 0.1 μm, and no other targets were found. In vitro experiments on the proliferation of JAK2-dependent and Flt3-related tumor cell lines with FM showed that the tumor cell lines had a significant inhibitory effect. The IC50 of half of the tumor cell lines was less than 0.5 μm, which was better than or equal to the similar drugs Ruxolitinib and Fedratinib. The effect of FM on tumor cells from MPN patients indicated that FM has the potential to treat MPN disease. In multiple animal models of bone marrow proliferative tumors with JAK2V617F mutations, FM showed superior efficacy and low toxicity (no obvious VISCAL toxicity) than existing drugs on the market, and the tumor inhibition effect of FM showed a good dose-dependent relationship. Objectives of Study Main Purpose: 1. Tolerance and safety of flonoltinib maleate Tablets tablets in patients with bone marrow proliferative tumors; 2. To observe the possible dose-limiting toxicity(DLT) of flonoltinib maleate tablets in patients with bone marrow proliferative tumors,To determine the maximum tolerated dose(MTD) of flonoltinib maleate tablets,To provide the basis for the recommended dose and design scheme of the later clinical trial. Secondary Purpose: 1. To evaluate the pharmacokinetic characteristics of single and repeated oral administration of flonoltinib maleate tablets in patients with bone marrow proliferative tumors; 2. To evaluate the primary efficacy of single and multiple oral flonoltinib maleate tablets in patients with bone marrow proliferative tumors.

A Platform Protocol to Investigate Post-Transplant Cyclophosphamide-Based Graft-Versus-Host Disease Prophylaxis in Patients With Hematologic Malignancies Undergoing Mismatched Unrelated Donor Peripheral Blood Stem Cell Transplantation

The purpose of this clinical trial is to compare drug combinations to learn which drugs work best to prevent graft-versus-host-disease (GVHD) in people who have received a stem cell transplant. The source of stem cells is from someone who is not related and has a different blood cell type than the study participant. The researchers will compare the new drug combination to a standard drug combination. They will also learn about the safety of each drug combination. Participants will: * Receive the standard or new drug combination after transplant * Visit the doctor's office for check-ups and tests after transplant that are routine for most transplant patients * Take surveys about physical and emotional well-being * Give blood and stool samples.
