Severe Thrombocytopenia from Trastuzumab and Pertuzumab Combination Therapy in a Patient with HER2-Positive Metastatic Rectal Cancer. (PubMed, Case Rep Oncol)
Consequently, we determined that the patient presented with a condition similar to immune thrombocytopenic purpura (ITP) and selected a treatment approach consisting of eltrombopag, a thrombopoietin receptor agonist. Although uncommon, anti-HER2 antibodies can cause severe thrombocytopenia. Furthermore, if thrombocytopenia persists after treatment discontinuation and the administration of corticosteroids, exploring treatment options aligned with managing ITP is essential.

Identification of Potential Inhibitors for Drug Resistance in Acute Lymphoblastic Leukemia through Differentially Expressed Gene Analysis and In Silico Screening. (PubMed, Anal Biochem)
Our aim is to determine differentially expressed genes (DEGs) related to Asparaginase, Daunorubicin, Prednisolone, and Vincristine resistance and identify potential inhibitors via docking...Following ADMET analysis, three drugs emerged as potential inhibitors: Flunarizine, Talniflumate, and Eltrombopag...This study promotes a further understanding of drug resistance in ALL, introducing novel genes for consideration in diagnostic screening. It also presents potential inhibitor candidates to tackle drug resistance through repurposing.

Transcription factor EB reprograms branched-chain amino acid metabolism and promotes pancreatic cancer progression via transcriptional regulation of BCAT1. (PubMed, Cell Prolif)
BCAA deprivation alone did not effectively inhibit PCC proliferation. However, BCAA deprivation combined with eltrombopag, a drug targeting TFEB, can play a two-pronged role in exogenous supply deprivation and endogenous utilisation blockade to inhibit the proliferation of pancreatic cancer to the greatest extent, providing a new therapeutic direction, such as targeted metabolic reprogramming of pancreatic cancer.

A case of successful CAR-T cell therapy for early isolated CNS recurrence of DLBCL with persistent CAR-T cells. (PubMed, Blood Cell Ther)
Chimeric antigen receptor T (CAR-T) cell therapy (lisocabtagene maraleucel; liso-cel) has been used to treat a few cases of isolated secondary CNS lymphoma. Herein, we report the case of a 66-year-old male diagnosed with diffuse large B-cell lymphoma (Ann Arbor grade IV; R-IPI, good risk; CNS IPI: Intermediate risk) who achieved complete remission (CR) after six courses of R-CHOP therapy...Seven high-dose methotrexate courses led to partial response. Subsequently, the patient received CAR-T cell therapy with tolerable adverse events - cytokine release syndrome treated with tocilizumab, no immune effector cell-associated neurotoxicity syndrome, and bone marrow failure treated with granulocyte-colony stimulating factor and eltrombopag...This case is the first to validate the efficacy and safety of CAR-T cell therapy for isolated secondary CNS lymphoma in clinical practice. Future accumulation of evidence on the efficacy and safety of CAR-T cell therapy is essential.

A Multistep In Silico Approach Identifies Potential Glioblastoma Drug Candidates via Inclusive Molecular Targeting of Glioblastoma Stem Cells. (PubMed, Mol Neurobiol)
The growth inhibitory effect of these final shortlisted compounds was examined on a panel of GBM cell lines and compared with temozolomide through the drug sensitivity EC50 values and AUC from the PRISM Repurposing Secondary Screen, and the IC50 values were obtained from GDSC portal...Our results show GSK-2126458/omipalisib, linifanib, drospirenone, eltrombopag, nilotinib, and PD198306 as candidate drugs which can be further evaluated for their anti-tumor potential against GBM. Through this work, we identified repurposed candidate therapeutics against GBM utilizing a GSC inclusive targeting approach, which demonstrated high in vitro efficacy and can prospectively evade drug resistance. These drugs have the potential to be developed as individual or combination therapy to improve GBM outcomes.

Multiparametric Flow Cytometry Based Quantification of the Marrow Hematopoietic Stem and Progenitor Compartment in Post Allogeneic Stem Cell Transplant Recipients with Poor Graft Function to Evaluate Hematopoietic Stem Cell Quality and Predict Clinical Outcomes: A Pilot Study (ASH 2023)
Thrombopoietin agonists such as eltrombopag (EPAG) or CD34-selected cell infusions are treatments offered for persistent cytopenias...Patient C1 who showed a spontaneous recovery of counts without the need of EPAG had the highest proportion of LT-HSCs despite lying in the second quartile of the cohort for both B cells as well as B-LPs. In conclusion, MP-FCM based analysis of the HSPC landscape in PGF marrow could be a robust prognostic biomarker in Allo-SCT patients.

Case Presentation: We present a 14-year-old Hispanic male with Philadelphia chromosome positive acute lymphoblastic leukemia (Ph+ ALL) who received a maternal haploidentical HSCT with myeloablative conditioning and post-transplant cyclophosphamide...Multiple treatments including romiplostim; eltrombopag; high dose immune globulin (IVIG); rituximab; methylprednisolone; and decitabine were not successful in improving platelet count (Figure 1)...Patient continues to maintain platelets above 100 x10 3/uL with no medication toxicities or adverse events noted. Patient has been able to return to his pre-alloHSCT lifestyle including contact sports and re-immunizations.

VAYHIT3: An Open-Label, Single-Arm, Phase II Trial to Evaluate the Efficacy and Safety of Ianalumab in Patients with Primary Immune Thrombocytopenia (ITP) Previously Treated with at Least 1 Corticosteroid and 1 Thrombopoietin Receptor Agonist (TPO-RA) (ASH 2023)
For patients who previously received corticosteroids and a TPO-RA, the choice of subsequent therapy (eg a different TPO-RA, rituximab, fostamatinib, mycophenolate mofetil, splenectomy) is not well defined. VAYHIT3 will evaluate the ability of a short therapeutic course of ianalumab to induce durable responses in patients who have received 2 or more prior lines of therapy, including at least 1 corticosteroid and 1 TPO-RA, for whom significant unmet needs exist. Current status: VAYHIT3 is recruiting. Ianalumab is also being investigated in 2 ongoing, randomized, double-blind, Phase III ITP trials: VAYHIT1 (NCT05653349) is assessing ianalumab versus placebo in addition to first-line corticosteroids, and VAYHIT2 (NCT05653219) is assessing ianalumab versus placebo in addition to eltrombopag in patients who failed first-line corticosteroid treatment.
