Trial in progress: Study design of a randomized, phase 3 trial evaluating the efficacy and safety of mezagitamab (TAK-079) compared with placebo in adults with chronic primary immune thrombocytopenia (ASH 2025) - P2, P3 | "Use of additional, stable Background ITPtherapy is permitted, including corticosteroids, thrombopoietin receptor agonists, and fostamatinib, as isuse of rescue therapy (corticosteroids, intravenous immunoglobulin, platelet transfusion) whenindicated. Given promising, early-stage results for anti-CD38 treatment in patients who have beendifficult to manage on current therapies, this global study will evaluate the efficacy and safety ofsubcutaneous mezagitamab as a potential novel therapy for patients with ITP who have had aninsufficient response or intolerance to prior therapy."

Real-world safety and effectiveness of hetrombopag in patients with primary immune thrombocytopenia (ASH 2025) - P | "Management of ITP remains challenging, particularly forpatients who are refractory or intolerant to first-line treatments such as corticosteroids or intravenousimmunoglobulin (IVIg). Hetrombopag demonstrated favorable real-world safety and effectiveness in patients withITP, leading to sustained improvements in platelet counts and reduced reliance on concomitanttherapies. These findings provide meaningful evidence supporting the use of hetrombopag in routineclinical practice and underscore its potential as a core component in the long-term management of ITP."

A Phase III Clinical Trial Program Investigating the Efficacy and Safety of Ianalumab in Patients with Primary Immune Thrombocytopenia (VAYHIT1 and VAYHIT2) and Warm Autoimmune Hemolytic Anemia (VAYHIA) (ASH 2023) - P2, P3 | "Ianalumab is a novel, fully human immunoglobulin G1 monoclonal antibody that targets BAFF receptor (BAFF-R) and has a unique dual mechanism of action: direct antibody-dependent cellular cytotoxicity-mediated B-cell depletion and inhibition of B-cell differentiation, proliferation and survival via blockade of BAFF-R-mediated signaling...Thrombopoietin receptor agonists (TPO-RAs), such as eltrombopag, are commonly used second-line ITP treatments and often achieve a response; however, responses are rarely maintained once treatment ends, so chronic administration is typically required. For wAIHA, few treatments have been approved, and patients rarely achieve durable responses on CS or off-label rituximab... These trials have been designed based on the hypothesis that, when administered early in disease progression, medical therapy targeting complementary physiological pathways may restore self-tolerance in patients with ITP and wAIHA. Ianalumab in combination with..."

Short-Term Efficacy of Combination Therapy with Recombinant Human Thrombopoietin (rh-TPO) and Thrombopoietin Receptor Agonists (TPO-Ra) in Patients with Severe Immune Thrombocytopenia (ASH 2023) - "When the risk of bleeding is becoming high or life-threatening bleeding events occurs, we often use a combination of therapies to rapidly raise platelets to the safe range, including platelet transfusions, high-dose glucocorticoid, and intravenous immunoglobulins...The patients were divided into three groups according to the medication used: rh-TPO group(rh-TPO 30000IU Qd), TPO-Ra group(Eltrombopag 25mg-75mg/d or Avatrombopag 2...5mg/d or Hetrombopagolamine 20mg-60mg/d), and rh-TPO+TPO-Ra group(combination of two drugs at the same dosage)...Further details are provided in Table 2. ConclusionThis retrospective study suggests that the patients with severe ITP who were refractory to glucocorticoids, the use of rh-TPO and TPO-Ra may rapidly increase to safe ranges, but the combination is not necessary."

`Integrated multi-modal dissection of IVIg-mediated immune reprogramming in lupus mice. (PubMed, Life Sci) - "Intravenous immunoglobulin (IVIg) is widely used to treat autoimmune diseases, yet its precise mechanisms of action in systemic lupus erythematosus remain incompletely understood...At the immune-cell level, IVIg was associated with alterations in T and B cell activation states, partial restoration of immune repertoire diversity, and shifts in dendritic cell populations. Collectively, our integrated analyses suggest that IVIg treatment is correlated with broad immunomodulatory changes in splenic immune composition in lupus-prone mice."

NURSING CARE OF 7 CASES OF EPSTEIN-BARR VIRUS INFECTION AFTER HEMATOPOIETIC STEM CELL TRANSPLANTATION TREATED BY CYTOTOXIC T LYMPHOCYTES (EHA 2025) - " Routine immunization The reduction of conventional immunosuppressants, the first-line treatment of acyclovir and human immunoglobulin antiviral therapy, and rituximab showed no significant decrease in the copy number of EBV. Ebvemia /PTLD is a serious complication after hematopoietic stem cell transplantation with high mortality.

CAR T cell manufacturing efficiency was lower in SLE compared to B-ALL patients, potentially due to differences in intrinsic T-cell properties. SLE patients demonstrated inferior persistence of CD19 CAR T cells, which may affect the efficacy."

Case Report: Anti-ADAM23 antibody: an overlooked autoantibody against VGKC-complex in autoimmune encephalitis. (PubMed, Front Immunol) - "During the early stages of the disease, the patient underwent several courses of intravenous immunoglobulin (IVIg) with limited efficacy. Following the addition of high-dose methylprednisolone pulse therapy, the patient's consciousness improved from coma to stupor and the seizures were relieved. We propose that anti-ADAM23 antibody, a previously overlooked autoantibody targeting the VGKC complex, may have diagnostic significance for autoimmune encephalitis."

Nanobody fusion enhances production of difficult-to-produce secretory proteins. (PubMed, J Biol Chem) - "The enhancement of N1 production is comparable or better than Fc fusion, and the effect is observed with all tested camelid Nb, but not with a shark Nb and to a lesser extent, with a human immunoglobulin heavy chain variable region. Importantly, the Nb in the fusion protein retained its antigen-binding capability, paving the way for the development of a dual-functional protein. Collectively, we present a novel strategy for enhancing the production of secretory proteins, which holds great promise in creating functional biological molecules for a wide range of applications."
