Venetoclax, a small molecule inhibitor of BCL-2, has demonstrated efficacy in treating acute leukemias and has been recommended as one of the first-line anti-leukemia therapies. Although venetoclax has been suggested to probably possess the ability to penetrate the central nervous system (CNS), current data to elucidate the characteristics of venetoclax in cerebrospinal fluid (CSF), bone marrow (BM), and plasma are still lacking. This study investigated the real-world characteristics of venetoclax concentrations in CSF, BM, and plasma in acute leukemia patients.

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.

Methods: We screened UHR patients with a survival of less than 24 months and we selected patients with a concurrent survival of more than 24 months as a control group. We retrospectively analyzed the clinical characteristics of UHR patients with newly diagnosed MM and screened related risk factors.
Background: Spleen tyrosine kinase (Syk) inhibitor is a treatment option for primary immune thrombocytopenia. We aimed to evaluate the safety, tolerability, pharmacokinetics, preliminary activity, and recommended phase 2 dose of sovleplenib in patients with primary immune thrombocytopenia.
Methods: This randomised, double-blind, placebo-controlled, phase 1b/2 study was conducted at nine hospitals in China.
The basic activities of daily life may affect the prognosis of multiple myeloma (MM) patients and the Barthel index (BI) is currently the most widely used tool to evaluate basic activities of daily life, but few studies have evaluated its prognostic value in MM. We retrospectively enrolled patients with newly diagnosed MM and analyzed the association between the BI and the survival of newly diagnosed MM patients. We totally analyzed 538 patients and found that median overall survival (OS) and progression-free survival (PFS) were significantly shorter in the low BI (≤ 85) group compared with the high BI (> 85) group.

Methods: We retrospectively analyzed 606 newly diagnosed MM patients treated with novel agents. The propensity score matching technique was used to reduce the bias between groups.
Background: Several studies showed that lack of CD56 expression was a poor prognostic factor for patients with newly diagnosed multiple myeloma (NDMM). However, other studies were not able to confirm the prognostic value of CD56 in NDMM. This study aimed to evaluate the prognostic value of CD56 expression for patients with NDMM who received autologous stem cell transplantation (ASCT).

Various MM cell lines for example, U266, including those resistant to bortezomib-resistant U266 cells were exposed to low nanomolar concentrations of bortezomib ± CPT and apoptosis monitored. Circularly permuted TRAIL and bortezomib synergistically induced apoptosis in both BTZ-naïve and -resistant cells.

Deep immunoparesis was defined that one of uninvolved immunoglobulins was below 50% the lower limit of normal ranges, partial immunoparesis was defined at least two suppressed uninvolved immunoglobulins. We found that patients with deep and partial immunoparesis had a significantly shorter median overall survival (OS) and progression-free survival (PFS).

Mcl-1 was up-regulated in all MM lines tested, including bortezomib-resistant lines, human MM xenograft mouse models, and primary CD138 MM cells. Mcl-1 over-expression significantly reduced bortezomib lethality, indicating a functional role for Mcl-1 in bortezomib resistance.

This phase 1b study evaluated the safety, tolerability, pharmacokinetics (PK), and efficacy of single-agent CPT in patients with relapsed or refractory multiple myeloma (RRMM), and aimed to identify the recommended dose for the phase 2 study.

The mechanism of the anti-myeloma effect of the immunomodulatory drug lenalidomide relies upon the binding of lenalidomide or an analogue to cereblon (CRBN) ubiquitin ligase, which inhibits it and results in the degradation of Ikaros-family zinc finger proteins 1 and 3 (IKZF1 and IKZF3). To determine whether the traditional Chinese medicine arsenic trioxide, could potentiate sensitivity of multiple myeloma (MM) cells to lenalidomide and identify the mechanism by which this happens, the present study investigated how arsenic trioxide affected CRBN on MM cell lines and examined the anti-myeloma effect and mechanism in the combination of arsenic trioxide and lenalidomide. The present study revealed that arsenic trioxide upregulates the transcription and protein levels of CRBN, the anti-myeloma target of lenalidomide, thus potentiating the sensitivity of multiple myeloma cells to lenalidomide and enhancing the lenalidomide-dependent degradation of IKZF1 and IKZF3.
