"We are excited to share groundbreaking data on SOT109, an innovative ADC designed to treat colorectal cancer and other GI malignancies," said Martin Steegmaier, Ph.D., chief scientific officer of SOTIO. "CDH17 has long been recognized as a highly compelling therapeutic target, yet previous non-ADC and ADC approaches have faced significant obstacles. Our cutting-edge design overcomes these challenges, utilizing state-of-the-art linker-payload technology and an optimized antibody backbone to enhance efficacy and tumor selectivity. Preclinical data indicate that our candidate not only delivers potent tumor cell killing but does so with an excellent safety profile and high therapeutic index. We believe this represents a major advancement in ADC development for GI cancers, and we look forward to filing an Investigational New Drug (IND) application for this program in Q2 2026."

CDH17 is a highly promising target homogenously overexpressed in more than 90% of colorectal cancers (CRC) and abundantly expressed in other GI cancers, including gastric, pancreatic, and esophageal cancers. In contrast, its expression in normal adult tissues is largely restricted to the GI tract, reducing the risk of off-target toxicity.

As CDH17 is an abundantly expressed and rapidly internalizing transmembrane protein on GI cancer cells, CDH17 is ideally suited for an ADC-mediated drug delivery approach. SOT109 is a fully human and highly specific ADC with exceptional binding and internalization properties against CDH17. SOT109 utilizes Synaffix’s clinically validated ADC platform, incorporating the SYNtecan E proprietary linker-payload system that contains an exatecan payload (DAR=4). For the treatment of CRC, SOT109’s exatecan payload is expected to demonstrate superior activity, reduced susceptibility to resistance, and an enhanced bystander effect due to its high cell permeability, setting it apart from other ADC payloads utilized to date.

In preclinical studies presented at World ADC London, SOT109 exhibited strong anti-tumor activity across multiple mouse xenograft models, including complete responses. It demonstrated favorable tolerability in an exploratory mouse study at doses up to 150 mg/kg. Furthermore, data from a subsequent toxicity study in non-human primates (NHPs) revealed that SOT109 displays a favorable therapeutic index underscoring its potential as a transformative therapy for GI cancers.

On March 3, 2025 Laekna (2105.HK) reported that the U.S. Food and Drug Administration (FDA) has approved the IND for LAE120, an internally discovered USP1 inhibitor, for the treatment of advanced solid tumors (Press release, Laekna Therapeutics, MAR 3, 2025, View Source [SID1234650861]).

LAE120 is a novel, allosteric and highly potent USP1 inhibitor, displaying monotherapy potency and combination activity with PARP inhibitor in HRD (homologous recombination deficiency) cancers. It has a unique chemical structure differentiated from all the other disclosed USP1 inhibitors and is expected to induce a different conformational change in USP1. LAE120 shows robust tumor inhibitory activity across various xenograft models such as MDA-MB-436 and K562 as a single agent and exhibits synergistic effect in combination with PARP inhibitors. It also demonstrates good therapeutic windows in GLP long-term toxicology study. Laekna is actively exploring partnerships to accelerate the clinical development of LAE120.

"Leveraging our deep know-how and extensive expertise in drug discovery, Laekna has developed a distinctive portfolio of innovative drug candidates through the close collaboration of our Med Chem, Biology and AIDD (AI-driven Drug Discovery) teams, continuously advancing preclinical drug candidates into clinical stage. Laekna has also significantly accelerated the progress of drug discovery by utilizing cutting-edge artificial intelligence tools," said Dr. Justin Gu, Chief Scientific Officer of Laekna. "We look forward to bringing novel drugs to patients as swiftly as possible," he added.

Advancing Diversified Pipelines

Laekna is actively advancing preclinical drug candidates. In the fourth quarter of 2024, another internally discovered anti-tumor drug candidate, LAE118, a potentially best-in-class, mutant-selective PI3Kαinhibitor, has advanced to IND-enabling study. PI3Kα mutations are prevalent in patients with breast, colorectal, lung, endometrial, and numerous other cancers. However, the first-generation drugs targeting PI3Kα inhibit the wild-type and mutant PI3Kα with equal potency, which raises concerns of tolerability and therapeutic efficacy.

As a novel allosteric inhibitor, LAE118 demonstrates excellent potency and selectivity towards various PI3Kα mutants. With superior anti-cancer efficacy and tolerability than other current PI3Kα inhibitors, LAE118 is potentially the best-in-class pan-mutant-selective PI3Kα inhibitor. Laekna has presented the preclinical characterization of LAE118 at the San Antonio Breast Cancer Symposium (SABCS) in December 2024. LAE118 is in IND-enabling studies and IND is expected to be filed in the fourth quarter of 2025.

Strategic Partnerships to Accelerate Globalization

"We will continue to advance and expand our product portfolio in the therapeutic areas where we have accumulated tremendous experience and extensive know-how," said Dr. Chris Lu, Chief Executive Officer of Laekna. "In November 2024, the Group has entered into a clinical collaboration agreement with Lilly (NYSE:LLY) to support and accelerate global clinical development of LAE102 for the treatment of obesity. We plan to pursue strategic partnerships with global leading pharmaceutical companies to accelerate clinical development and commercialization of our drug candidate assets. We keep advancing and expanding our pipeline and are committed to bringing life-changing medicines to more people around the world," he added.

A Potential Step Toward Transforming Pancreatic Cancer Treatment

Silexion’s latest study could mark an important advancement in validating systemic administration of SIL-204. The study specifically assessed the therapy’s ability to reduce primary tumor growth and inhibit metastatic spread in clinically relevant orthotopic pancreatic cancer models—providing a more accurate representation of human disease progression than traditional subcutaneous xenograft models.

Silexion’s work with SIL-204 has already demonstrated compelling preclinical efficacy, including a 50% reduction in tumor growth and complete necrosis in half of treated tumors in previous systemic administration studies. Moreover, SIL-204 has shown sustained therapeutic levels for over 56 days from a single dose—an unprecedented achievement in RNAi-based therapies for KRAS-driven cancers.

Why This Matters: A Potential First for Metastatic Pancreatic Cancer

KRAS-driven cancers remain among the most aggressive and difficult-to-treat malignancies, particularly in pancreatic cancer, where over 90% of tumors harbor KRAS mutations. While other companies have attempted to target KRAS with small molecule inhibitors, Silexion’s RNAi-based approach aims to silence multiple key KRAS mutations, including G12D, G12V, G12R, Q61H, and G13D—offering a broader and potentially more effective therapeutic strategy.

The ability to target both primary and metastatic pancreatic cancer via systemic administration would represent a major breakthrough, as Silexion has not previously demonstrated this effect in metastatic models. If the orthotopic model results show significant impact on metastases, this could mark a critical validation step, potentially differentiating SIL-204 from existing KRAS-targeting approaches and opening the door to expanded clinical applications.

The industry seems to be closely watching Silexion’s progress in light of the recent wave of multi-billion-dollar acquisitions in precision oncology. With major players like Pfizer acquiring Seagen for $43 billion and AbbVie purchasing Immunogen for $10.1 billion, the demand for novel cancer therapies seems to have increased in recent years. According to news reports, Maxim Group recently reaffirmed its strong buy rating on SLXN with a $9 price target, citing the company’s strong clinical trajectory and the ongoing validation of its RNAi platform.

Upcoming Data Readout: A Potential Critical Catalyst

Silexion’s announcement that initial results from the orthotopic model study will be released in March 2025 has sparked significant interest. If the data is positive, it could provide further confirmation of SIL-204’s ability to target both primary and metastatic pancreatic cancer, marking the first time the company demonstrates systemic efficacy against metastatic disease.

If the upcoming results align with previous systemic administration findings and show significant impact on metastases, SIL-204 could emerge as a leading next-generation RNAi therapy for KRAS-driven cancers—potentially, in the future, reshaping the treatment paradigm for one of the deadliest malignancies.

Silexion Therapeutics has continued to execute on its strategy, pushing the boundaries of RNAi therapeutics for one of the most aggressive cancers. With data from the orthotopic pancreatic cancer study expected in March, many will likely be watching closely. If the upcoming results are positive and demonstrate impact on metastases, they could serve as a major catalyst for the company, potentially redefining its role in the precision oncology landscape.

Given the strong track record of preclinical success, increasing interest, and a competitive landscape ripe for M&A activity, Silexion Therapeutics is undoubtedly a company to watch in 2025.

On March 3, 2025 Daiichi Sankyo reported positive topline results from the DESTINY-Gastric04 phase 3 trial showed ENHERTU (trastuzumab deruxtecan) demonstrated a statistically significant and clinically meaningful improvement in the primary endpoint of overall survival (OS) compared to ramucirumab and paclitaxel in patients with second-line HER2 positive (IHC 3+ or IHC 2+/ISH+) unresectable and/or metastatic gastric or gastroesophageal junction (GEJ) adenocarcinoma (Press release, Daiichi Sankyo, MAR 3, 2025, View Source [SID1234650858]).

At a planned interim analysis, the Independent Data Monitoring Committee recommended unblinding the trial based on the superior efficacy of ENHERTU.

ENHERTU is a specifically engineered HER2 directed DXd antibody drug conjugate (ADC) discovered by Daiichi Sankyo (TSE: 4568) and being jointly developed and commercialized by Daiichi Sankyo and AstraZeneca (LSE/STO/Nasdaq: AZN).

Gastric cancer is associated with a poor prognosis, particularly in advanced stages of the disease where the five-year survival rate is 5% to 10%.1,2 Following disease progression in the first-line metastatic setting of HER2 positive gastric cancer, there historically have been no HER2 directed medicines that have demonstrated a survival benefit in the second-line metastatic setting in a randomized clinical trial.3

ENHERTU is currently approved in more than 65 countries based on DESTINY-Gastric01, a randomized phase 2 trial, and DESTINY-Gastric02 and DESTINY-Gastric06, two single-arm phase 2 trials. DESTINY-Gastric04 is the first phase 3 trial of ENHERTU in HER2 positive advanced gastric cancer.

"ENHERTU is the first HER2 directed medicine to demonstrate an improvement in overall survival in a randomized phase 3 trial in the second-line metastatic setting of patients with HER2 positive gastric cancer, reinforcing previous findings seen in our other earlier phase gastric cancer trials," said Ken Takeshita, MD, Global Head, Oncology R&D, Daiichi Sankyo. "With these DESTINY-Gastric04 results, we will work with global regulatory authorities to seek approval in regions where ENHERTU is not currently indicated as a second-line option, as well as work to secure full approval in regions where ENHERTU is conditionally approved."

"We are committed to advancing the care of patients with metastatic gastric cancer and continuing to understand the role of ENHERTU in earlier lines of treatment," said Susan Galbraith, MBBChir, PhD, Executive Vice President, Oncology Hematology R&D, AstraZeneca. "The results of DESTINY-Gastric04 show that second-line treatment with ENHERTU can extend survival compared with a chemotherapy-based regimen and should be considered for all eligible patients with HER2 positive metastatic gastric cancer."

The safety profile seen in DESTINY-Gastric04 is consistent with the established safety profile of ENHERTU.

Data from DESTINY-Gastric04 will be presented at an upcoming medical meeting and shared with global regulatory authorities.

About DESTINY-Gastric04
DESTINY-Gastric04 is a global, randomized, open-label, phase 3 trial evaluating the efficacy and safety of ENHERTU (6.4 mg/kg) versus ramucirumab and paclitaxel in patients with HER2 positive (IHC 3+ or IHC 2+/ISH+) unresectable and/or metastatic gastric or GEJ adenocarcinoma with disease progression on or after a trastuzumab-containing regimen.

The primary endpoint is OS. Secondary endpoints include investigator-assessed progression-free survival, objective response rate, duration of response, disease control rate and safety.

DESTINY-Gastric04 enrolled 494 patients in Asia, Europe and South America. For more information about the trial, visit ClinicalTrials.gov.

About HER2 Positive Gastric Cancer
Gastric (stomach) cancer is the fifth most common cancer worldwide and the fifth leading cause of cancer-related death.1,2 Approximately one million cases of gastric cancer were diagnosed in 2022.2 Gastric cancer is associated with a poor prognosis, particularly in advanced stages of the disease where the five-year survival rate is 5% to 10%.1,2

HER2 is a tyrosine kinase receptor growth-promoting protein expressed on the surface of many types of tumors, including gastric cancer.4 Approximately one in five gastric cancers are considered HER2 positive.4,5

Following disease progression in the first-line metastatic setting of HER2 positive gastric cancer, there historically have been no HER2 directed medicines that have demonstrated a survival benefit in the second-line metastatic setting in a randomized clinical trial.3
