A Phase 1/2 Study of T-cell Expressing a Novel CD19 Chimeric-Antigen Receptor (SHB-02-CD19) in Patients With CD19-expressing B-cell Malignancies

This is a phase I/II trial of SHB-02-CD19, T-cell expressing an anti-CD19 Chimeric-Antigen-Receptor (CAR) in patients with CD19 expressing B-cell malignancies. This trial is an open label, single-arm, for pediatric and adult patients with relapsed/refractory B-cell malignancies.

Immunophenotypic Evaluation of CD305 and CD85d in B-Cell Lymphoid Neoplasms

Inhibitory immune receptors, including CD85d and CD305 (LAIR-1), act as immune checkpoint-like molecules. They contain immunoreceptor tyrosine-based inhibitory motifs (ITIMs) that recruit SH2-domain phosphatases (e.g., SHP-1), which suppress cellular activation (7,8). CD85d is predominantly expressed in myeloid cells, including monocytes, macrophages, dendritic cells, and granulocytes. It is also differentially expressed on NK, T, B cells, and neutrophils. It is expressed at high levels in tumor cells, facilitating immune escape by promoting immune suppression, allowing for tumor evasion (9). CD85d is widely expressed across AML, so it is a top candidate, due to its traditional association with myeloid phenotypes and limited expression in normal haematopoiesis (10). It was reported to be expressed in B cells of CLL patients in contrast to normal B cells. Its expression in CLL patients denotes a distinctive feature, which may be acquired during malignant transformation (8). Therefore, CD85d may have significant prognostic, mechanistic, and therapeutic roles in hematologic malignancies (11). As a novel biomarker in solid malignant tumors to predict the prognosis of patients, upregulation of CD85d in tumors is associated with worse tumor phenotypes. Targeting CD85d may be an effective tool for targeted cancer therapy (12). Concerning CD305, it has been reported in about 60% of CLL patients and may be used as an effective prognostic marker to predict TTFT in CLL patients (13). Despite their potential clinical significance, the expression patterns of CD85d and CD305 across B-cell lymphoid neoplasms subtypes remain incompletely identified. Illustrating their role may help to determine TTFT, prognosis, therapeutic targeting, and refinement of B-cell neoplasms classification in line with WHO-HAEM5 standards.

Study to Evaluate Adverse Events and Change in Disease Activity in Adult Participants With B-Cell Malignancies Receiving Oral ABBV-525 Tablets

B-cell malignancies are a group of cancers of B lymphocytes, a type of white blood cell responsible for fighting infections. The purpose of this study is to assess safety, tolerability, pharmacokinetics and preliminary efficacy of ABBV-525 as a monotherapy. ABBV-525 is an investigational drug being developed for the treatment of B-Cell Malignancies. Study doctors put the participants in groups called treatment arms. Participants will receive ABBV-525 at different doses. Approximately 150 adult participants will be enrolled in the study across sites worldwide. In part 1 (dose escalation), participants will receive escalating oral doses of ABBV-525. In part 2 (dose optimization), participants will receive one of two oral doses of ABBV-525, until the recommended phase 2 dose (RP2D) is determined. In part 3 (dose expansion), participants will receive the RP2D oral dose of ABBV-525. The estimated duration of the study is up to 64 months. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic and may require frequent medical assessments, blood tests, and scans.

A Phase 1/2 Study of T-cell Expressing an Anti-CD22 Chimeric-Antigen Receptor (SHB-04-CD22) in Patients With CD22-expressing B-cell Malignancies

This is a phase I/II trial of T-cell expressing an anti-CD22 Chimeric-Antigen-Receptor (CAR) in patients with CD22 expressing B-cell malignancies. This trial is an open label, single-arm, for pediatric and adult patients with relapsed/refractory B-cell malignancies.

Exploratory Study on the Treatment of Relapsed and Refractory B-cell Malignant Tumors With WGb-0301 Injection

Malignant hematological tumors mainly derived from adult B cells are mainly acute lymphoblastic leukemia (ALL) and non Hodgkin lymphoma (NHL). Overall, although existing therapies have significantly improved the survival rates of most patients, the treatment of relapsed/refractory patients still faces significant challenges. CD19 is one of the most clinically valuable targets for B-cell malignant hematological tumors. The advent of COVID-19 vaccine has brought LNP mRNA technology into the public's view. After years of development, it not only shines brilliantly in COVID-19 vaccine, but also is widely used in the treatment and exploration of cancer, rare diseases and other fields. The core of LNP mRNA technology targeting CD19 is to encapsulate the mRNA encoding specific proteins in lipid nanoparticles and deliver them to the body through intravenous or intramuscular injection. The experimental drug WGb-0301 injection is a CD19 based messenger RNA (mRNA) therapeutic mRNA drug, formed by loading mRNA onto lipid nanoparticles (LNP). WGb-0301 injection has demonstrated efficient B-cell clearance activity and good safety in non clinical settings, supporting further clinical exploration in B-cell malignancies. It is expected to provide an innovative, safe, and accessible immunotherapy for B-cell malignancies, bringing better clinical benefits to more patients with B-cell malignancies.

Bispecific CAR T Cells for B-cell Malignancies (BaseCAR-01 Trial)
