Phase 3 hematology

PURPOSE: T cells modified with chimeric antigen receptors (CARTs) have demonstrated efficacy for hematologic malignancies; however, benefit for patients with CNS tumors has been limited. To enhance T cell activity against GD2+ CNS malignancies, we modified GD2-directed CART cells (GD2.CARTs) with a constitutively active interleukin (IL)-7 receptor (C7R-GD2.CARTs). METHODS: Patients age 1-21 years with H3K27-altered diffuse midline glioma (DMG) or other recurrent GD2-expressing CNS tumors were eligible for this phase I trial (ClinicalTrials...

HBI0101 is an academic chimeric antigen receptor T (CART) targeted to BCMA for the treatment of relapsed and refractory multiple myeloma (RRMM) and light chain amyloidosis. Herein, we present the Phase Ib/II results of fifty heavily pre-treated RRMM patients dosed with 800x106 CART cells (NCT04720313). Inclusion criteria were relatively permissive (i.e., performance status and baseline organ function) and consequently, about half of the enrolled patients would have been ineligible for pivotal clinical trials...

Estimating progression-free survival (PFS) and overall survival (OS) superiority during clinical trials of multiple myeloma (MM) has become increasingly challenging as novel therapeutics have improved patient outcomes. Thus, it is imperative to identify earlier endpoint surrogates that are predictive of long-term clinical benefit to expedite development of more effective therapies. Minimal residual disease (MRD)-negativity is a common intermediate endpoint that has shown prognostic value for clinical benefit in trials of patients with multiple myeloma (MM)...

PURPOSE: The aim of this study was to compare the physiological adaptations of males and females to repeated sprint training in hypoxia. METHODS: Active males and females completed 7 weeks of repeated sprint training in normoxia (RSN, FiO2 = 0.209, males: n = 11, females: n = 8) or hypoxia (RSH, FiO2 = 0.146, males: n = 12, females: n = 10). Before (Pre-) and after (Post-) training, a repeated sprint ability test (RSA) was performed (10 s cycle sprints with 20 s recovery between sprints, until exhaustion), and aerobic and anaerobic qualities were evaluated in normoxia...

BACKGROUND: Developmental delays are common among children with sickle cell disease (SCD). Existing guidelines support consistent screening to increase the identification of deficits and support referral to rehabilitative interventions, yet adherence remains variable. This study sought to assess current practices and identify barriers and facilitators to improve developmental screening for children 0-3 years with SCD. PROCEDURE: A mixed methods approach, guided by the Exploration and Preparation stages of the Exploration, Preparation, Implementation, and Sustainment (EPIS) framework, assessed developmental screening practices among primary care providers and hematologists...

Primary cold agglutinin disease (CAD) is a rare autoimmune hemolytic anemia caused by cold-reactive antibodies that bind to red blood cells and lead to complement-mediated hemolysis. Patients with primary CAD experience the burden of increased health resource utilization and reduced quality of life. The standard-of-care (SOC) in patients with primary CAD has included cold avoidance, transfusion support, and chemoimmunotherapy. The use of sutimlimab, a humanized monoclonal antibody that selectively inhibits C1-mediated hemolysis, was shown to reduce transfusion-dependence and improve quality of life across two pivotal phase 3 studies, further supported by 2-year extension data...

This study determined whether the isomeric or isoenergetic/isoproteic substitution of corn in the diet of Jersey heifers in the rearing phase with cracker residue would impair growth and health, as well as reducing production costs. Fourteen Jersey females in the growth phase were used, separated into two treatments with seven animals in each lot in collective pens. The experiment used 7-month-old animals (169.8 ± 2.89 kg) and lasted for four months. In Experiment I, the animals were divided into two groups: treatment, with the partial replacement of 40% corn with cracker residue, and control, in which the animals consumed the same diet with 100% corn (isometric diet kg for kg)...

BACKGROUND AND OBJECTIVES: We determined normalization rates for hemoglobin, lactate dehydrogenase (LDH), and fatigue in patients with paroxysmal nocturnal hemoglobinuria (PNH) treated with pegcetacoplan (PEG) in the PEGASUS (NCT03500549) and PRINCE (NCT04085601) phase III trials. METHODS: Enrolled patients had PNH and hemoglobin < 10.5 g/dL despite ≥ 3 months of eculizumab (ECU) [PEGASUS], or were complement component 5 (C5) inhibitor-naive, receiving supportive care only, with hemoglobin less than the lower limits of normal (LLN) [PRINCE]...

BACKGROUND: Metastatic castration-resistant prostate cancer (mCRPC) remains uniformly lethal. Prostate specific membrane antigen (PSMA) is a transmembrane glycoprotein overexpressed in prostate cancer. 131I-PSMA-1095 (also known as 131I-MIP-1095) is a PSMA-targeted radioligand which selectively delivers therapeutic radiation to cancer cells and the tumor microenvironment. METHODS: We conducted a single-arm, phase 2 trial to assess efficacy and tolerability of 131I-PSMA-1095 in mCRPC patients who had exhausted all lines of approved therapy...

OBJECTIVE: In the present study we aimed to review the evolution and function of the maternal medicine multidisciplinary team (MMMDT) meeting of a maternal medicine service of a tertiary level stand-alone maternity hospital. METHODS: We conducted a retrospective descriptive study of all minutes of MMMDT meetings from 2014 to 2020, with the aim of evaluating meeting characteristics and patient demographics. RESULTS: There were 575 multidisciplinary team (MDT) discussions of 486 women during 43 meetings in the 7 year period...

Background : There is a clinical imperative to devise metrics to prognosticate dengue severity. Our objective was to determine the association between longitudinal trends in atypical lymphocytes and large immature cell count with platelet count and dengue severity. Materials and methods : Retrospective analysis of longitudinally measured clinical and hematological data from ( n = 79) hospitalized dengue patients was done. Results : The cohort consisted of patients with dengue fever without warning signs (DFWOWS) ( n = 40, females = 14, and age = 19...

Biomarkers for cytopenias following CAR T-cell treatment in relapsed/refractory (RR) multiple myeloma (MM) are not completely defined. We prospectively analysed 275 sequential peripheral blood (PB) samples from 58 RRMM patients treated with BCMA-targeted CAR T cells, and then divided them into three groups: (i) baseline (before leukapheresis), (ii) ≤day+30, and (iii) >day+30 after CAR T-cell therapy. We evaluated laboratory data and performed flow cytometry to determine the (CAR) T-cell subsets. Baseline hyperferritinaemia was a risk factor for long-lasting grade ≥3 anaemia (r = 0...

We hypothesized that fit older patients with acute myeloid leukemia (AML) treated with decitabine (DEC) would report better health-related quality of life (HRQoL) outcomes compared to those receiving intensive chemotherapy (IC). We conducted a phase 3 randomized trial to compare DEC (10-day schedule) to IC (3+7) in older fit AML patients. HRQoL was a secondary endpoint, and it was assessed with the EORTC QLQ-C30 and the QLQ-ELD14. The following scales were a priori selected for defining the primary endpoint: physical and role functioning, fatigue, pain, and burden of illness...

BACKGROUND: N-(-9 acridinyl)-b-alanine hydrochloride (S-300) is the main byproduct of red blood cell (RBC) amustaline/glutathione(GSH) pathogen reduction, currently undergoing phase III US clinical trials following successful European studies(1-3). Phosphatidylinositol glycan, class A (Pig-a) X-linked gene mutagenesis is a validated mammalian in vivo mutation assay for genotoxicity, assessed as clonal loss of glycosylphosphatidylinositol-linked CD59 cell-surface molecules on reticulocytes (RETs) and RBCs...

Objective: To retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China. Methods: Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed...

BACKGROUND: Chronic myeloid leukemia (CML) or chronic granulocytic leukemia is a myeloproliferative neoplasm indicated by the presence of the Philadelphia (Ph+) chromosome. First-line tyrosine kinase inhibitor, imatinib, is the gold standard for treatment. However, there has been known unresponsiveness to treatment, especially due to the involvement of other genes, such as the Janus kinase 2 (JAK2) gene. This study aimed to evaluate the relationships between JAK2 levels and complete hematological response (CHR), as well as early molecular response (EMR) after 3 months of imatinib treatment in patients with chronic phase CML...

Mass spectrometry (MS) can detect multiple myeloma-derived monoclonal proteins in peripheral blood (PB) with high sensitivity, potentially serving as a PB assay for measurable residual disease (MRD). This study evaluated the significance of PB MS MRD negativity during post-transplant therapy in patients with newly diagnosed multiple myeloma. Serum samples from 138 patients treated in the phase 3 ATLAS trial of post-transplant maintenance with either carfilzomib, lenalidomide, dexamethasone or lenalidomide alone were analyzed using EXENT MS methodology...

Venetoclax, a highly selective BCL-2 inhibitor, combined with hypomethylating agents (HMAs) azacitidine or decitabine, is approved for the treatment of newly diagnosed acute myeloid leukemia (ND AML) in patients who are ineligible to receive intensive chemotherapy. Previous clinical studies initiated venetoclax plus HMA in an inpatient setting owing to concerns of tumor lysis syndrome (TLS). This study (NCT03941964) evaluated the efficacy and safety of venetoclax plus HMA in a United States community-based outpatient setting in patients with ND AML (N = 60) who were treatment naïve for AML, ineligible to receive intensive chemotherapy, had no evidence of spontaneous TLS at screening, and were deemed as appropriate candidates for outpatient initiation of venetoclax plus HMA by the investigator...
