Aponermin or placebo in combination with thalidomide and dexamethasone in the treatment of relapsed or refractory multiple myeloma (CPT-MM301): a randomised, double-blinded, placebo-controlled, phase 3 trial.

Background: Aponermin, a circularly permuted tumor necrosis factor-related apoptosis-inducing ligand, is a potential death receptor 4/5-targeted antitumour candidate. Previous phase 1/2 studies have demonstrated the efficacy of aponermin in patients with relapsed or refractory multiple myeloma (RRMM). To confirm the superiority of aponermin plus thalidomide and dexamethasone (aponermin group) over placebo plus thalidomide and dexamethasone (placebo group) in RRMM, a randomized, double-blinded, placebo controlled phase 3 trial was performed.

Romiplostim in primary immune thrombocytopenia that is persistent or chronic: phase III multicenter, randomized, placebo-controlled clinical trial in China.

Background: Multiple trials have confirmed that romiplostim could increase platelet count in individuals with primary immune thrombocytopenia (ITP), but no related study has assessed Chinese patients.

Objectives: To assess the effectiveness of romiplostim as a second-line treatment of persistent or chronic ITP in Chinese adults.

Methods: This phase III multicenter, randomized, placebo-controlled, double-blind, then open-label clinical trial (NCT02868099, CTR20150395) was conducted at 28 investigational sites in China.

Background: Thrombopoietin receptor agonists (TPO-RAs) are promising therapeutic strategy for patients with immune thrombocytopenia (ITP). We conducted this phase 1 trial (NCT02614846) to evaluate the preliminary efficacy and safety of hetrombopag (a TPO-RA) in patients with ITP.

Methods: Patients with ITP who had an insufficient response or had progressed on at least one standard treatment for ITP were given hetrombopag orally at an initial dose of 5 mg once daily for up to 6 weeks.

Dose tapering to withdrawal stage and long-term efficacy and safety of hetrombopag for the treatment of immune thrombocytopenia: Results from an open-label extension study.

Background: The efficacy of hetrombopag in Chinese patients with immune thrombocytopenia (ITP) has been demonstrated in a randomized, double-blind, placebo-controlled, multicenter, phase III trial (NCT03222843).

Objective: This study aimed to report comprehensive data on a ≤6-week dose tapering to withdrawal (Stage 3) and an additional 24-week long-term extension period (Stage 4) in this phase III trial.

Patients/methods: Patients who fulfilled the screening criteria were eligible to enter Stage 3 or 4.

A multicenter, randomized phase III trial of hetrombopag: a novel thrombopoietin receptor agonist for the treatment of immune thrombocytopenia.

Background: Hetrombopag, a novel thrombopoietin receptor agonist, has been found in phase I studies to increase platelet counts and reduce bleeding risks in adults with immune thrombocytopenia (ITP). This phase III study aimed to evaluate the efficacy and safety of hetrombopag in ITP patients.

Methods: Patients who had not responded to or had relapsed after previous treatment were treated with an initial dosage of once-daily 2.

Ibrutinib in CLL/SLL: From bench to bedside (Review).

B-cell receptor (BCR) signaling is important for the development and maturation of normal B-cells and plays a key role in B-cell malignancies. Bruton's tyrosine kinase (BTK), a crucial terminal kinase enzyme in BCR signaling, has emerged as an attractive target and has been successfully applied in the treatment of hematological malignancies. Ibrutinib, a BTK inhibitor, has demonstrated marked efficacy and tolerability in treatment-naïve, relapsed/refractory chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) and mantle cell lymphoma (MCL).

Metformin and cancer: An existing drug for cancer prevention and therapy.

Metformin is a standard clinical drug used to treat type 2 diabetes mellitus (T2DM) and polycystic ovary syndrome. Recently, epidemiological studies and meta-analyses have revealed that patients with T2DM have a lower incidence of tumor development than healthy controls and that patients diagnosed with cancer have a lower risk of mortality when treated with metformin, demonstrating an association between metformin and tumorigenesis. and studies have revealed that metformin has a direct antitumor effect, which may depress tumor proliferation and induce the apoptosis, autophagy and cell cycle arrest of tumor cells.

RNA interfering of CXCR4 inhibits the adhesion, invasion, and tumorigenicity of acute monocytic leukemic cells .

To investigate the effect of CXCR4 gene expressing on the proliferation, adhesion, and invasion of human monocytic leukemic cell line SHI-1 and its tumorigenic capacity in nude mouse. The SHI-1 cells were firstly infected with the rescued recombinant lentivirus to establish SHI-1/CXCR4i cell line. The expression of CXCR4, MMP-2 and MMP-9 in the SHI-1/CXCR4i cell was determined by real time quantitative PCR and flow cytometry.

Chronic Myelocytic Leukemia (CML) Patient-Derived Dendritic Cells Transfected with Autologous Total RNA Induces CML-Specific Cytotoxicity.

The oncogenic bcr/abl1 fusion gene is a chronic myelogenous leukemia (CML)-specific antigen which is absent in normal tissues. This makes bcr/abl1 a perfect target for developing CML vaccines that elicit specific immune responses against minimal residual disease while sparing normal tissue. The aim of this study was to use different methods to induce dendritic cells (DCs) derived from patients with CML (CML-DCs) and analyze them for CML-specific tumor cytotoxicity for immune therapy.

[RNAi-mediated Silencing of CXCR4 Inhibits the Adhesion, Invasion and Tumorigenicity of Acute Monocytic Leukemic Cell Line SHI-1].

Objective: To investigate the effect of CXCR4 gene on the proliferation, adhesion, invasion and tumorigenicity of a human monocytic leukemic cell line SHI-1.

Methods: The lentivirus vector silencing the expression of CXCR4 was constructed for infection of SHI-1 cells silencing expression of CXCR4 in SHI-1 cells. The expression of CXCR4, MMP-2 and MMP-9 was detected by real time PCR.

[Expression and significance of HSP90 in plasma of patients with multiple myeloma].

This study was purposed to investigate the expression of heat shock protein 90 (HSP90) in peripheral blood plasma of patients with multipl myeloma (MM), and to explore its possible role in the pathogenesis of MM, and its relationship with treatment, prognosis and the outcome of patients. The peripheral blood samples from 58 patients with MM and 20 healthy volunteers were collected. The plasma concentration of HSP90 in patients and healthy volunteers was measured by ELISA.
