Evaluation of gecacitinib vs hydroxyurea in patients with intermediate-2 or high-risk myelofibrosis: final analysis results from a randomized phase 3 study.

To compare the efficacy and safety of gecacitinib (also known as jaktinib) with hydroxyurea (HU) in treating myelofibrosis (MF) patients. In this multicenter, randomized phase 3 trial (ZGJAK016), intermediate- or high-risk primarily JAK inhibitor naïve MF patients were assigned in a 2:1 ratio to receive either gecacitinib (100 mg twice a day, BID) or HU (500 mg BID). The primary endpoint was the proportion of patients with ≥35% reduction in spleen volume (SVR35) from baseline at week 24.

Lenalidomide-induced pure red cell aplasia is associated with elevated expression of MHC-I molecules on erythrocytes.

The RVd therapy, combining lenalidomide, bortezomib, and dexamethasone, is a mainstay treatment for multiple myeloma. A multiple myeloma patient developed pure red cell aplasia (PRCA) following RVd treatment, despite the absence of common PRCA triggers. In vitro analyses reveal lenalidomide as a pivotal disruptor of erythropoiesis.

Identifying immune checkpoints on dysregulated T-cells as prognostic biomarkers for multiple myeloma patients with COVID-19.

Background: Broad T cell phenotypic alterations and potential dysfunctions were prominent in COVID-19. There are few and inconclusive data about the role of immune checkpoints for T cell exhaustion/activation during SARS-CoV-2 infection in multiple myeloma (MM) patients.

Methods: We tested T cell subsets and immune checkpoints in 177 MM patients with COVID-19, as well as in 32 healthy infected controls and 42 uninfected MM patients.

Vaginal involvement as a rare extranodal manifestation in advanced-stage follicular lymphoma: a case report and literature review.

Apart from bone marrow involvement, extranodal involvement of follicular lymphoma (FL) is rare. Gynecologic FL is seldom reported, among which the vagina is the rarest involved site. No vaginal involvement in advanced-staged FL was reported before.

Percutaneous vertebroplasty/kyphoplasty contributes to the improved outcome in patients with newly diagnosed multiple myeloma: A single center cohort study.

Objective: To evaluate the efficacy and prognosis of percutaneous vertebroplasty/kyphoplasty (PVP/PKP) in patients with newly diagnosed multiple myeloma (NDMM).

Methods: Clinical data of NDMM patients who underwent PVP/PKP during front-line regimen at Peking Union Medical College Hospital from January 1, 2003, to June 30, 2023, were analyzed. Patients with comparable bone diseases not receiving orthopedic surgery were selected as controls.

Myc rearrangement redefines the stratification of high-risk multiple myeloma.

Background: Myc rearrangement (Myc-R) is a controversial factor linked to adverse outcomes in newly diagnosed multiple myeloma (NDMM).

Aims: This study aimed to evaluate the impact of Myc-R on the prognosis of NDMM patients and its role in risk stratification compared with traditional high-risk cytogenetic abnormalities (HRCAs).

Materials & Methods: A total of 417 NDMM patients enrolled from May 2009 to September 2022 were included.

Assessment of prolonged proteasome inhibition through ixazomib-based oral regimen on newly diagnosed and first-relapsed multiple myeloma: A real-world Chinese cohort study.

Objective: To evaluate the effectiveness, safety, and convenience of in-class transition (iCT) from intravenous bortezomib-based induction to ixazomib-based oral regimens.

Methods: This retrospective real-world study was conducted in 16 Chinese hospitals between October 2017 and April 2023 and analyzed newly diagnosed (NDMM) and first-line relapsed multiple myeloma (FRMM) patients who attained at least a partial response from bortezomib-based induction therapy, followed by an ixazomib-based oral regimen for 2 year or until disease progression or intolerable toxicity.

Results: The study enrolled 199 patients, median age: 63 years old, male 55.

Chemokine Receptor 4-Targeted PET/CT With 68 Ga-Pentixather Detects More Lesions Than 68 Ga-Pentixafor PET/CT in Multiple Myeloma.

An 83-year-old woman with newly diagnosed multiple myeloma (MM) was enrolled in our 68 Ga-pentixather and 68 Ga-pentixafor PET/CT trial for evaluation of tumor burden. 68 Ga-pentixather PET/CT detected more focal bone lesions, and the uptake levels of focal bone lesions on 68 Ga-pentixather PET/CT were higher than those on 68 Ga-pentixafor PET/CT. This suggests that 68 Ga-pentixather PET/CT may be an alternative imaging modality and more sensitive in detecting MM lesions than 68 Ga-pentixafor PET/CT.

Prognostic Implications of Circulating Plasma Cell Percentage in Multiple Myeloma and Primary Plasma Cell Leukemia Defined by New Criteria.

Introduction: The definition of primary plasma cell leukemia (pPCL) has been revised from ≥20% to ≥5% circulating plasma cells (CPC). However, the precise prognosis associated with CPC remains controversial. This study aimed to investigate prognostic biomarkers for myeloma patients based on CPC presence.

Efficacy, safety, and survival findings after long-term follow-up of ZGJAK002: A phase 2 study comparing jaktinib at 100 mg twice daily (BID) and 200 mg once daily (QD) in patients with myelofibrosis.

Jaktinib, a novel JAK and ACVR1 inhibitor, has exhibited promising results in treating patients with myelofibrosis (MF). ZGJAK002 is a Phase 2 trial aimed to assess the efficacy and safety of jaktinib 100 mg BID (N = 66) and 200 mg QD (N = 52) in JAK inhibitor-naive patients with intermediate- or high-risk MF. We herein present the long-term data with a median follow-up of 30.

Pure red cell aplasia and minimal residual disease conversion associated with immune reconstitution in a patient with high-risk multiple myeloma.

A second bone marrow aspiration and biopsy showed pure red cell aplasia in this case.

Lenalidomide or bortezomib as maintenance treatment remedy the inferior impact of high-risk cytogenetic abnormalities in non-transplant patients with newly diagnosed multiple myeloma: a real-world multi-centered study in China.

Maintenance treatment is a pivotal part in the whole process management of multiple myeloma (MM), which further deepens response and improves survival. However, evidence of maintenance in non-transplant MM patients is inadequate in real-world practice. Here, we retrospectively analyzed the efficacy and survival of 375 non-transplant MM patients from 11 centers between 2010 and 2021 in north China.

Patient-Reported Outcomes in Young Adults with Myeloproliferative Neoplasms.

Introduction: Genetic landscape, disease characteristics, and clinical outcomes of young adults with myeloproliferative neoplasms (MPNs) were reported. However, data on patient-reported outcomes (PROs) in young adults with MPNs were rare.

Methods: We conducted a multicenter, cross-sectional study to compare the PROs in respondents with thrombocythemia (ET), polycythemia vera (PV), and myelofibrosis (MF) by age at survey, including the young group (18-40 years), middle-aged group (41-60 years), and elderly group (>60 years).

Front-line treatment efficacy and clinical outcomes of elderly patients with multiple myeloma in a real-world setting: A multicenter retrospective study in China.

Background: The use of proteasome inhibitors (PIs), new immune modulators (IMiDs), and other new drugs, as well as high-dose chemotherapy combined with autologous stem cell transplantation has considerably improved the survival of young patients with multiple myeloma (MM). However, the improvement in survival among elderly patients remains insufficient. Optimal treatment recommendation models for elderly patients with MM have not been developed especially there are quite few study in the real world.

Safety and efficacy of jaktinib in the treatment of Janus kinase inhibitor-naïve patients with myelofibrosis: Results of a phase II trial.

Myelofibrosis (MF) is associated with several constitutional symptoms. Currently, there are few therapeutic options for MF. Jaktinib, a novel, small-molecule inhibitor of JAK, is currently being studied for its potential to treat MF.

Efficacy and safety of blinatumomab in Chinese adults with Ph-negative relapsed/refractory B-cell precursor acute lymphoblastic leukemia: A multicenter open-label single-arm China registrational study.

Objectives: The prognosis for adults with relapsed/refractory (R/R) B-cell precursor acute lymphoblastic leukemia (BCP-ALL) is poor. Blinatumomab is a CD3/CD19-directed BiTE® (bispecific T-cell engager) molecule approved globally for the treatment of BCP-ALL in adults and children. This multicenter open-label single-arm China registrational study evaluated the safety, efficacy, and pharmacokinetics of blinatumomab in Chinese adults with Philadelphia chromosome-negative (Ph-) R/R BCP-ALL (NCT03476239).
