LILRB2, also known as ILT4, is an inhibitory receptor widely expressed on the surface of myeloid cells that also contributes significantly to immune suppression in the tumor microenvironment (TME). ES009 specifically binds to a unique epitope on human LILRB2 and potently blocks LILRB2 binding to multiple ligands. By blocking LILRB2-mediated inhibitory signaling, ES009 can reprogram myeloid cells from anti-inflammatory phenotype into pro-inflammatory phenotype, and reinvigorate T cell functionalities. ES009 has demonstrated exceptional potential to reverse immune suppression in the TME and promote anti-tumor immunity in preclinical studies.

"LILRB2 is a key immune checkpoint for tumor immunotherapy whose suppression of immune response is proved as one mechanism of anti-PD(L)1 resistance. With a keen interest in revolutionizing therapies for cancer patients non-responsive or resistant to PD(L)1 treatment, we developed ES009 which has shown best-in-class potential. We believe in the power of enhanced innate immunity in treating cancer and have developed a highly differentiated myeloid cell focused therapeutics portfolio. We will work relentlessly to bring these highly promising therapies to cancer patients with unmet medical needs," said Dr. Hongtao Lu, Co-founder and CSO of Elpiscience.

Under the agreement, NCATS will gain access to proprietary targeted degraders of TEAD from Beactica to evaluate their efficacy in disease-relevant preclinical models. NCATS will also map systematically the drug-combination landscape for selected preclinical candidates by performing a high-throughput drug-combination screen using a collection of about 3,000 oncology-focused, mechanistically annotated drugs.

Pharmacological modulation of the Hippo signalling pathway has translational potential in both regenerative and oncology indications. Small-molecule modulators of the TEAD transcription factors have recently emerged as a novel anti-cancer drug-class, to specifically target Hippo-pathway-deficient cancers.

"We are very pleased to be selected by NCATS and look forward to collaborating with them to maximize the therapeutic potential of our targeted degraders of TEAD." said Dr Per Källblad, CEO of Beactica Therapeutics. "Their extensive expertise and capabilities will accelerate our project’s progress, enhancing its potential to positively impact patients".

About YAP–TEAD

YAP1 (Yes-associated protein 1) is a coactivator that together with TEAD 1–4 (TEA Domain) transcription factors play key roles in the Hippo signalling pathway that regulate cell proliferation, apoptosis, and stemness. Dysregulation of the Hippo pathway and subsequent activation of TEAD has been reported in a wide range of cancers such as squamous cell carcinoma, head and neck, gynaecological, and gastrointestinal cancers. The first clinical proof-of-concept for drugging the Hippo–YAP–TEAD pathway was recently achieved with the TEAD inhibitor VT3989, which was presented at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting in April 2023.

Mission Bio Announces Launch of Single-Cell Measurable Residual Disease (MRD) Assay Aimed to Advance Personalized Healthcare for Blood Cancer Patients

On September 26, 2023 Mission Bio, a leader in single-cell multi-omic solutions for precision medicine, reported the commercial launch of the Tapestri Single-cell MRD (scMRD) AML Multiomics Assay (Press release, Mission Bio, SEP 26, 2023, View Source [SID1234635429]). The company designed the scMRD AML Multiomics Assay to bring unprecedented resolution to disease relapse and recurrence in acute myeloid leukemia (AML), demonstrating the potential of single-cell DNA and protein multiomics to identify therapeutic targets in recurrent AML.

"Through our early access program, world-leading clinicians and scientists within academia and the biopharma industry have provided robust validation showing that our scMRD AML Multiomics Assay can provide impactful insights into AML evolution and patient relapse," said Todd Druley, MD, PhD, Chief Medical Officer of Mission Bio. "By simultaneously interrogating DNA and protein targets at single-cell resolution and characterizing genotypic and immunophenotypic drifts over disease course, our assay not only identifies patients with recurrent AML, but potentially offers clinicians actionable treatment targets. Tapestri could transform care with comprehensive MRD detection for potentially guiding targeted treatments in AML, multiple myeloma (MM), and other blood cancers."

As the only solution to integrate genotypic and immunophenotypic assessment, the scMRD AML Multiomics Assay targets 40 genes for single-cell DNA sequencing based on current international AML MRD guidelines, such as European LeukemiaNet, and 17-plex antibody-oligonucleotide conjugate (AOC) panel curated for key biomarkers associated with AML MRD.

Through a seamlessly integrated workflow, the assay allows clinician-researchers to:

Distinguish true MRD from pre-leukemic or precursor clones with a limit of detection of 0.01%,
Reveal clonal architecture (co-occurrence and zygosity of mutation) and uncover the order of acquisition of mutations (phylogeny),
Track clonal dynamics and immunophenotypic drifts through disease course to identify therapeutic targets and therapy-resistance subclones.
"Relapse continues to be a major challenge in cancer care, especially in the treatment of patients with AML. The problem is that current tools, like bulk NGS and flow cytometry, lack the clonal resolution and specificity to detect the treatment-resistant cancer cells still hiding in the shadows," said P.J.M. (Peter) Valk, PhD, Principal Investigator at Erasmus MC in Rotterdam, Netherlands. "Mission Bio’s unique approach to characterizing MRD could dramatically change how we stratify patients in clinical trials and create personalized care strategies in the future."

A recent study published in Science Advances and led by Wenbin Xiao, MD, PhD from the lab of world-leading leukemia specialist & physician-scientist Ross Levine, MD, Deputy Physician in Chief for Translational Research at MSK demonstrated the potential of the scMRD AML Multiomics Assay to better predict AML recurrence. The researchers found that the assay could detect clinically relevant variants missed by bulk next-generation sequencing with 0.01% limit of detection. Additionally, the researchers tapped the multiomic capabilities of the assay to illustrate the clonal architecture distinguishing leukemic clones from preleukemic clones and hematopoietic clones.

Taken together, the data suggest that the scMRD AML Multiomics Assay could help identify AML relapse and has the potential to provide data-driven guidance to healthcare professionals regarding personalized treatment strategies, disease monitoring, and clinical trial stratification.

Mission Bio continues to provide its customers with innovative solutions for clonal profiling and surveillance, including single-cell multi-omic tools for studying other blood cancers such as MM. The new scMRD AML Multiomics Assay is now commercially available. For more information on the assay and the bioinformatics analysis and reporting capabilities, visit View Source
