Prelude Therapeutics and AbCellera Enter Partnership to Develop First-in-Class Precision Antibody Drug Conjugates in Oncology

On November 1, 2023 Prelude Therapeutics Incorporated ("Prelude") (Nasdaq: PRLD) and AbCellera (Nasdaq: ABCL) reported a multi-year, multi-program partnership to discover, develop, and commercialize potentially first-in-class treatments for patients with cancer (Press release, Prelude Therapeutics, NOV 1, 2023, View Source [SID1234636680]). The collaboration combines Prelude’s expertise in targeted protein degradation, medicinal chemistry, and clinical development with AbCellera’s antibody discovery and development engine to generate novel precision antibody drug conjugates (ADCs). The first program, which benefits from a lead panel of antibodies previously discovered by AbCellera, is focused on ADCs to broaden the reach of Prelude’s small molecule SMARCA2 selective degraders to address a larger patient population.

About Givastomig

Givastomig, also known as TJ-CD4B/ABL111, is a bispecific antibody designed to bind to Claudin 18.2 (CLDN18.2) as a tumor engager and 4-1BB as a conditional T-Cell activator. It binds to tumor cells expressing various levels of CLDN18.2, i.e., gastric cancer and pancreatic cancer cells, and conditionally activates intra-tumoral T cells at the tumor site through the 4-1BB arm. Givastomig appears to effectively maintain a strong tumor binding property and anti-tumor activity attributable to a synergistic effect of both CLDN18.2 antibody and 4-1BB antibody while avoiding or minimizing liver toxicity and systemic immunotoxicity commonly seen with 4-1BB antibodies as a drug class. Being developed under collaboration between I-Mab and ABL Bio, a clinical-stage biotechnology company in South Korea, givastomig is currently being investigated in a Phase 1 clinical study in the U.S. and China. In March 2022, the U.S. Food and Drug Administration (FDA) granted Orphan Drug Designation for givastomig for the treatment of gastric cancer, including cancer of the gastroesophageal junction.

About TJ-L14B/ABL503

Being developed jointly with ABL Bio (Kosdaq: 298380, hereafter "ABL"), TJ-L14B/ABL503 is a differentiated PD-L1-based bispecific antibody with the PD-L1 arm as the tumor-dependent T-cell activator and the 4-1BB arm as the conditional T cell activator upon tumor engagement. Using ABL’s "Grabody-T" bispecific antibody platform technology, TJ-L14B/ABL503 stimulates 4-1BB activation only in the presence of PD-L1 expressing tumor cells to minimize the risk of off-tumor toxicity. Preclinical studies have demonstrated that the bispecific antibody shows better anti-tumor activity than equimolar doses of single agents alone or in combination. A Phase 1 study is currently being conducted in the U.S. and South Korea.

During this year’s meeting, Lunit plans to highlight the predictive value and analytical power of its Lunit SCOPE suite in various types of cancer, such as non-small cell lung cancer (NSCLC) and triple-negative breast cancer (TNBC).

A collaborative study with the Samsung Medical Center assessed tumor-infiltrating lymphocytes (TILs) using AI-powered spatial analysis with Lunit SCOPE IO in EGFR-mutated non-small cell lung cancer (NSCLC) patients pre- and post-tyrosine kinase inhibitors (TKI) treatment. The study found that EGFR-TKI affects the immune landscape of EGFR-mutated NSCLC as higher PD-L1 expression and differential immune phenotypes. Patients with an inflamed immune phenotype after EGFR-TKI treatment showed a more favorable response to subsequent immune checkpoint inhibitors (ICI) treatment. The study found that inflamed immune phenotype after EGFR-TKI treatment showed a higher overall response (OR; 40.0% vs. 7.5%) and better progression-free survival (PFS; 4.1 vs. 1.4 months) than other immune phenotype groups (excluded and desert type) to ICI treatment.

In another study, Lunit assessed the distribution of TILs in six subtypes of triple-negative breast cancer (TNBC) and their association with driver mutations. By analyzing The Cancer Genome Atlas breast cancer dataset using Lunit SCOPE IO, the study found that the immunomodulatory (IM) subtype of TNBC has a significantly higher mean intratumoral (iTIL), stromal (sTIL), and total TIL (tTIL) score than other TNBC subtypes. Additionally, TNBC samples with PIK3CA mutation/amplification or PTEN loss and BRCA1 or BRCA2 mutation each showed a higher total TIL score than those without mutation. This demonstrates that the TIL distribution can be a valuable biomarker for navigating the optimal treatment strategy in TNBC.

Lunit also explored the correlation between methylation burden and AI-based immune phenotype in The Cancer Genome Atlas (TCGA) Pan-Cancer Atlas dataset, which included 22 tumor types and a total of 6243 samples. The study found that the degree of methylation aberrancy in cancer is linked with TIL infiltration in the tumor microenvironment (TME) assessed by Lunit SCOPE IO.

Another study investigated the effect of tumor fragmentation index (TFI), the number of tumor fragments per total tumor area, in TME. In the study, a total of 7,472 TCGA H&E whole-slide images across 23 cancer types were analyzed with Lunit SCOPE IO. The study found that tumors with high TFI are closely correlated with high fibroblast infiltration but showed low IFNG, IL1A, and IL17A, genes that trigger inflammation as cancer grows.

"We are excited to be back to this year’s SITC (Free SITC Whitepaper) with our six groundbreaking studies that demonstrate the potential of our Lunit SCOPE suite in guiding treatment strategies for NSCLC and TNBC. We’ve also found valuable biomarkers and correlations that could lead to predictive information about patients’ immune response and the metastatic potential of the cancer tumor," said Brandon Suh, CEO of Lunit. "Through our participation in the SITC (Free SITC Whitepaper) conference, we will continue to back the efficacy of our Lunit SCOPE suite. At the same time, we are committed to seeking collaborations with healthcare giants worldwide to further our mission of advancing tailored cancer treatment."
