Pancreatic ductal adenocarcinoma (PDAC) is characterized by a dismal prognosis even among patients who undergo surgical resection. Local recurrence and distant metastasis are common, often leading to treatment failure. Elevated carbohydrate antigen 19-9 (CA19-9) levels post resection indicate aggressive tumor biology and higher risk of recurrence. The median interval is approximately 3 months between CA19-9 elevation and radiological recurrence. [1][2] Current standard adjuvant therapies have limited effectiveness for high-risk patients, highlighting the urgent need for novel strategies.

This trial enrolled patients with Claudin18.2 positive PDAC who have undergone curative-intent resection, with abnormal CA19-9 after 3 months adjuvant chemotherapy and no evidence of recurrence. From Sep 15, 2023 to April 11, 2025 (data cut-off date), six patients received satri-cel infusion and completed at least 4 weeks of follow-up.

With a median follow-up of 6.05 months from infusion, only one patient experienced disease recurrence, while others are still under disease free. The median disease-free survival (DFS) and median overall survival (OS) were not reached (NR). The 9-month DFS rate from surgery was 83.3%. Notably, one patient who has completed 52-week follow-up post infusion is still under follow-up without disease recurrence. Moreover, significant decline in CA19-9 levels post infusion was observed in five (83.3%) patients, with reductions ranging from 51.3% to 96.1%.

All patients developed Grade 1 or 2 cytokine release syndrome (CRS) after the first satri-cel infusion. For the second infusion administered in one patient, grade 3 CRS accompanied by hypotension was observed, which was resolved within three days following tocilizumab treatment. All patients experienced gastrointestinal disorders, such as nausea and vomiting, which were all Grade 1 or 2. Only one case of Grade 3 gastritis occurred. No immune effector cell-associated neurotoxicity syndrome (ICANS) was reported.

Dr. Zonghai Li, Founder, Chairman of the Board, Chief Executive Officer, and Chief Scientific Officer of CARsgen Therapeutics, said, "We are pleased to see that satri-cel has shown promising preliminary efficacy with a manageable safety profile in the highly challenging setting of pancreatic cancer adjuvant therapy. For patients at high risk of recurrence after surgical resection of pancreatic cancer, there are currently very few effective treatment options. In this trial, the sustained disease-free survival and marked declines in CA19-9 levels suggest that satri-cel, an innovative cellular immunotherapy, may clear minimal residual disease and potentially alter the disease course for these patients. Furthermore, we are actively advancing clinical trials exploring satri-cel for gastric cancer adjuvant therapy and as a sequential treatment following first-line gastric cancer therapy, with the goal of providing better curative opportunities for a broader patient population."

About Satri-cel
Satri-cel is an autologous CAR T-cell product candidate against the protein Claudin18.2 that has the potential to be the first-in-class globally. Satri-cel targets the treatment of Claudin18.2-positive solid tumors with a primary focus on gastric/gastroesophageal junction adenocarcinoma (G/GEJA) and pancreatic cancer (PC). Initiated trials include investigator-initiated trials (CT041-CG4006, NCT03874897), a confirmatory Phase II clinical trial for advanced G/GEJA in China (CT041-ST-01, NCT04581473), a Phase Ib registrational trial for PC adjuvant therapy in China (CT041-ST-05, NCT05911217), an investigator-initiated trial for satri-cel be used as consolidation treatment following adjuvant therapy in patients with resected G/GEJA (CT041-CG4010, NCT06857786), an investigator-initiated trial for satri-cel as a sequential therapy following first-line treatment in patients with advanced G/GEJA (CT041-CG4011, NCT07179484), and a Phase 1b/2 clinical trial for advanced gastric or pancreatic adenocarcinoma in North America (CT041-ST-02, NCT04404595).

The Center for Drug Evaluation (CDE) of National Medical Products Administration (NMPA) of China has accepted the New Drug Application (NDA) for satri-cel for the treatment of Claudin18.2-positive advanced G/GEJA in patients who have failed at least two prior lines of therapy on June 25, 2025. It has been granted Priority Review in May 2025 and Breakthrough Therapy Designation in March 2025 by the CDE. Satri-cel was granted Regenerative Medicine Advanced Therapy designation by U.S. FDA for the treatment of advanced G/GEJA with Claudin18.2-positive tumors in January 2022. Satri-cel received Orphan Drug designation from the U.S. FDA for the treatment of G/GEJA in September 2020.

ATG-022 (CLDN18.2 antibody-drug conjugate)
Title: Phase I/II study of Claudin 18.2 ADC ATG-022 in patients with advanced gastric/ gastroesophageal junction cancer (CLINCH)
Abstract Number: 2907
Presentation Number: 2113P

ATG-022 and CLINCH Study Overview

ATG-022 is a CLDN18.2-targeted ADC with sub-nM affinity and fast internalization. Using a VC-MMAE linker-payload (DAR 4), ATG-022 has demonstrated potent activity across tumors with high, low, and ultra-low CLDN18.2 expression.
The ongoing Phase I/II CLINCH study consists of dose escalation and dose expansion phases. In dose escalation, patients with advanced solid tumors regardless of CLDN18.2 expression receive ATG-022 once every three weeks (0.3-3.0 mg/kg Q3W) to evaluate the safety, tolerability, and pharmacokinetics; CLDN18.2-positive (≥ IHC 1+, 1%) patients are treated at 1.8 mg/kg or 2.4 mg/kg in dose expansion to evaluate the efficacy and safety.
ATG-022 has been granted two Orphan Drug designations (ODDs) by the U.S. Food and Drug Administration (FDA) for the treatment of gastric cancer and pancreatic cancer, and in August 2025 obtained Breakthrough Therapy Designation from China’s National Medical Products Administration (NMPA) for treating CLDN18.2-positive, HER-2 negative unresectable or metastatic gastric or gastroesophageal junction adenocarcinoma (GC/GEJC) who have received at least two prior lines of therapy.
Key Results from the CLINCH Study

Efficacy Data
Among GC/GEJC patients with moderate/high CLDN18.2 expression (IHC 2+ > 20%), the 2.4 mg/kg dose cohort observed 1 complete response (CR), 11 partial responses (PRs) and 15 stable diseases (SDs), resulting in an objective response rate (ORR) of 40% (12/30) and a disease control rate (DCR) of 90% (27/30). The median progression-free survival (mPFS) was 6.97 months and the 12-month overall survival (OS) rate was 66.2%. In the 1.8 mg/kg dose cohort, there were 1 CR, 9 PRs, and 11 SDs, resulting in an ORR of 40% (10/25) and a DCR of 84% (21/25).
Among GC/GEJC patients with low/ultra low CLDN18.2 expression (IHC 2+ ≤ 20%), patients treated at the efficacious dose of 1.8-2.4 mg/kg achieved 1 CR and 5 PRs, resulting in an ORR of 33.3% (6/18) and a DCR of 50% (9/18). The patient with CR has demonstrated durable response and has been on the study for over 22 months.
To date, the study has observed three CRs, one from each of the three forementioned cohorts (two dose cohorts among CLDN18.2 mid/high expressors and the cohort of low/ultra low CLDN18.2 expressors). This broad-spectrum antitumor activity indicates ATG-022’s potential as a new treatment option for a broader population of patients).
Safety Data
At 2.4 mg/kg in the dose expansion, 45.8% of patients had ≥1 treatment-emergent adverse events (TEAEs), 60.4% of patients had grade ≥3 TEAEs. The most common grade ≥3 treatment-related adverse events (TRAEs, ≥5% of patients) were neutrophil count decrease (16.7%), decreased appetite (14.6%) and anaemia (8.3%).
In the dose-expansion phase, the 1.8 mg/kg cohort demonstrated excellent safety and tolerability, with only 13.6% of patients reporting serious TEAEs and 18.2% reporting Grade ≥3 TEAEs. The favorable safety profile of this dose level support its potential use in first-line combination regimens with chemotherapy and immune checkpoint inhibitors.
No ophthalmological toxicities or interstitial lung disease have been observed.
Conclusions and Outlook

ATG-022 demonstrated a manageable safety profile and encouraging antitumor effects in GC/GEJC adenocarcinoma patients with a broad range of CLDN18.2 expressions, thus supporting further clinical investigation in patients with variable CLDN18.2 expressions. In addition to GC/GEJC, preliminary efficacy has been observed in other non-GI tumor types which will be reported at upcoming conferences.
The 2.4 mg/kg cohort showed a favorable safety profile, while the 1.8 mg/kg cohort demonstrated even better safety and tolerability. These findings provide strong support for advancing ATG-022 in combination with immune checkpoint inhibitors and chemotherapy in first-line treatment settings, paving the way to significantly expand its clinical reach and commercial potential.
The Phase II dose expansion study of ATG-022 is going smoothly in China and Australia. In parallel, Antengene is actively preparing for combination therapy studies involving ATG-022 to further advance its clinical development.

In the OptiTROP-Lung04 trial, a total of 376 patients were randomized (1:1) to receive sac-TMT monotherapy or chemotherapy.

As at the data cut-off date July 06, 2025, the median follow-up is 18.9 months. the median Progression-Free Survival (PFS) was 8.3 months in the sac-TMT group and 4.3 months in the chemotherapy group. Sac-TMT significantly improved PFS over chemotherapy with 51% lower risk of disease progression or death (hazard ratio (HR) 0.49; 95% confidence interval (CI), 0.39-0.62; P<0.0001).

At the preplanned interim analysis of overall survival (OS), the OS was not reached (NR) in the sac-TMT group and 17.4 months in the chemotherapy group. sac-TMT significantly improved OS over chemotherapy with 40% lower risk of death (hazard ratio (HR) 0.6; 95% CI: 0.44-0.82; two-sided P=0.001). In the supplemental analysis, when censoring patients at the date of initiation of subsequent ADCs, sac-TMT significantly improved OS over chemotherapy with 44% lower risk of death (HR, 0.56; 95% CI, 0.41 – 0.77).

Sac-TMT significantly improved ORR as compared to chemotherapy (60.6% vs 43.1%)

A consistent PFS and OS benefit of sac-TMT over chemotherapy was observed across all predefined subgroups, including prior EGFR-TKI therapy, presence of liver or brain metastases, and EGFR mutation subtype.

The incidence of any grade treatment-related adverse events (TRAEs) and grade ≥3 TRAEs was similar between the two groups. The most common TRAEs for both sac-TMT and chemotherapy were hematologic toxicities. No TRAEs led to discontinuation or death, and no cases of interstitial lung disease/pneumonitis were reported in the sac-TMT group. Ocular surface toxicity: occurred in 9.6% of patients in the sac-TMT group, all of which were grade 1 – 2.

As a conclusion, sac-TMT demonstrates highly statistically significant and clinically meaningful improvements in PFS and OS compared to platinum-based chemotherapy and showed a manageable safety profile, with no unexpected safety signals identified. Several global phase 3 studies of sac-TMT monotherapy (NCT06305754, NCT06074588) and combination study with osimertinib in China (NCT06670196) in EGFR-mutant NSCLC are ongoing.

Professor Zhang Li, National Lead Principal Investigator from Sun Yat-sen University Cancer Center, commented: "Compared to platinum-based doublet chemotherapy, sac-TMT not only significantly prolonged PFS but also demonstrated a statistically significant and clinically meaningful improvement in OS within this patient population. This achievement marks a major breakthrough in global lung cancer treatment—sac-TMT, as a monotherapy, demonstrated statistically significant and clinically meaningful improvements in both PFS and OS in the Phase III trial for patients with EGFR-TKI-resistant NSCLC. This study provides highly valuable, new evidence-based guidance for lung cancer management worldwide and has the potential to reshape the therapeutic landscape for EGFR-TKI-resistant NSCLC "

About sac-TMT

Sac-TMT, a core product of the Company, is a novel human TROP2 ADC in which the Company has proprietary intellectual property rights, targeting advanced solid tumors such as NSCLC, BC, GC, gynecological tumors, among others. Sac-TMT is developed with a novel linker to conjugate the payload, a belotecan-derivative topoisomerase I inhibitor with a drug-to-antibody-ratio (DAR) of 7.4. Sac-TMT specifically recognizes TROP2 on the surface of tumor cells by recombinant anti-TROP2 humanized monoclonal antibodies, which is then endocytosed by tumor cells and releases the payload KL610023 intracellularly. KL610023, as a topoisomerase I inhibitor, induces DNA damage to tumor cells, which in turn leads to cell-cycle arrest and apoptosis. In addition, it also releases KL610023 in the tumor microenvironment. Given that KL610023 is membrane permeable, it can enable a bystander effect, or in other words kill adjacent tumor cells.

In May 2022, the Company licensed the exclusive rights to MSD (the tradename of Merck & Co., Inc, Rahway, NJ, USA) to develop, use, manufacture and commercialize sac-TMT in all territories outside of Greater China (which includes Mainland China, Hong Kong, Macao and Taiwan).

To date, three indications for sac-TMT have been approved and marketed in China for the treatment of adult patients with unresectable locally advanced or metastatic triple negative breast cancer (TNBC) who have received at least two prior systemic therapies (at least one of them for advanced or metastatic setting), EGFR mutation-positive locally advanced or metastatic non-squamous NSCLC following progression on EGFR-TKI therapy and platinum-based chemotherapy and EGFR mutant-positive locally advanced or metastatic non-squamous NSCLC who progressed after treatment with EGFR-TKI therapy. Sac-TMT is the first TROP2 ADC drug approved for marketing in lung cancer globally. In addition, the new indication applications for sac-TMT for the treatment of adult patients with unresectable locally advanced, metastatic HR+/HER2- BC who have received prior endocrine therapy and other systemic treatments in the advanced or metastatic setting was accepted by the Center for Drug Evaluation (CDE) of the National Medical Products Administration (NMPA), and was included in the priority review and approval process.

As of today, the Company has initiated 9 registrational clinical studies in China. MSD has initiated 15 ongoing Phase 3 global clinical studies of sac-TMT as a monotherapy or with pembrolizumab or other anti-cancer agents for several types of cancer. These studies are sponsored and led by MSD.

On October 19, 2025 Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), reported positive results from the Phase III IMvigor011 study evaluating Tecentriq (atezolizumab) as an adjuvant treatment for people with muscle-invasive bladder cancer (MIBC) who are at risk of recurrence after surgery (cystectomy) and have detectable circulating tumor DNA (ctDNA). In this ctDNA-guided setting, Tecentriq reduced the risk of death (overall survival, OS) by 41% and the risk of disease recurrence or death (disease-free survival, DFS) by 36%, both compared with placebo. This ctDNA-guided approach, using Natera’s SignateraTM ctDNA Molecular Residual Disease (MRD) test, spared people at low risk of recurrence from unnecessary treatment and side effects. The safety profile was consistent with previous studies of Tecentriq.

These results are being presented as part of the Presidential Symposium at the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress 2025. They will also be discussed with health authorities, including the U.S. Food and Drug Administration.

"These clinically meaningful results show that Tecentriq helped people with muscle-invasive bladder cancer live longer and without their disease returning," said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. "The use of serial ctDNA testing to detect molecular residual disease may also advance bladder cancer treatment by combining a precision diagnostic with cancer immunotherapy."

"Even after surgery, most people with muscle-invasive bladder cancer will face the physical and emotional toll of further treatment," said Thomas Powles, lead principal investigator of IMvigor011, professor of genitourinary oncology; chair of Barts Cancer Centre at St. Bartholomew’s Hospital. "These results indicate that with Signatera ctDNA testing, we may be able to identify those at risk of recurrence who could benefit from adjuvant atezolizumab treatment and spare others from unnecessary therapy, paving the way for a more personalized treatment approach."

At median follow up of 16.1 months, median DFS was 9.9 months in the Tecentriq arm versus 4.8 months in the placebo arm (stratified hazard ratio [HR]=0.64; 95% CI: 0.47-0.87, p=0.0047). Median OS was 32.8 months in the Tecentriq arm versus 21.1 months in the placebo arm (HR=0.59; 95% CI: 0.39-0.90, p=0.0131). People who persistently tested for no detectable ctDNA had low risk of recurrence.

More than 150,000 people worldwide are diagnosed with MIBC each year. It is an aggressive type of cancer, with poor long-term outcomes and high treatment burden. Despite this, personalized treatment approaches lag behind other cancer types. ctDNA-guided treatment could change this, by helping healthcare professionals tailor treatment more precisely to improve clinical benefit and reduce unnecessary intervention.

About the IMvigor011 study
IMvigor011 [NCT04660344] is a global Phase III, randomized, placebo-controlled, double-blind study designed to evaluate the efficacy and safety of adjuvant treatment with Tecentriq (atezolizumab) compared with placebo in participants with muscle-invasive bladder cancer (MIBC) who are circulating tumor DNA (ctDNA)-positive and are at risk of recurrence following cystectomy. IMvigor011 utilized Natera’s Signatera as the clinical trial assay. This personalized ctDNA test for the detection of MRD is currently under review by the FDA for use as a companion diagnostic. 761 people participated in the surveillance phase of IMvigor011 and those with positive Signatera tests (250 people) joined the treatment phase, where they received either Tecentriq or placebo. The primary endpoint is investigator-assessed disease-free survival (DFS). Secondary endpoints include overall survival (OS) and tolerability, amongst others.

About Tecentriq (atezolizumab)

Tecentriq (atezolizumab) is a monoclonal antibody designed to bind with a protein called PD-L1, which is expressed on tumor cells and tumor-infiltrating immune cells, blocking its interactions with both PD-1 and B7.1 receptors. By inhibiting PD-L1, Tecentriq may enable the re-activation of T cells. Tecentriq may also affect normal cells.

On October 19, 2025 Verastem Oncology (Nasdaq: VSTM), a biopharmaceutical company committed to advancing new medicines for patients with RAS/MAPK-pathway-driven cancers, reported positive, updated efficacy and safety data from partner GenFleet Therapeutics’ Phase 1/2 monotherapy study in China of GFH375, an oral KRAS G12D (ON/OFF) inhibitor (VS-7375 outside of China) for patients with KRAS G12D mutant advanced pancreatic ductal adenocarcinoma (PDAC). Among 59 heavily pre-treated patients with advanced disease, who received two or more prior lines of therapy, an overall response rate (ORR) of 41% was achieved at the monotherapy recommended Phase 2 dose (RP2D) of 600 mg daily (QD). The updated data were featured in a late-breaking abstract for oral presentation by GenFleet Therapeutics at the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress 2025 on October 19, 2025, in Berlin, Germany.

"Patients with advanced pancreatic cancer and a KRAS G12D mutation tend to have a worse prognosis compared to other KRAS mutations. We are pleased to see that the updated data presented by our partner, GenFleet Therapeutics, continues to demonstrate encouraging clinical responses at the recommended Phase 2 dose, in a heavily pre-treated, often difficult to treat, patient population," said Dan Paterson, president and chief executive officer of Verastem Oncology. "These data add to the growing body of evidence supporting the therapeutic potential of KRAS G12D inhibition and importantly provide valuable insights as we continue to advance through our Phase 1/2a trial with VS-7375."

ESMO 2025 Presentation Highlights

GenFleet reported that 66 patients with advanced KRAS G12D mutant PDAC were treated with 600 mg QD of GFH375 monotherapy. In the study, 95.5% of patients were diagnosed with stage IV disease at study entry, and 68.2% of patients had received at least two prior lines of anticancer therapies, with 92.4% of patients receiving gemcitabine-based regimens and more than 50% receiving fluorouracil or irinotecan-containing regimens. As of the data cutoff of September 27, 2025, 59 efficacy-evaluable patients had at least one post-treatment tumor assessment and achieved an ORR of 40.7% (24/59) (confirmed and unconfirmed) and a disease control rate (DCR) of 96.7% (57/59) with the majority of patients (91.5%) experiencing a reduction in target lesions. Overall survival (OS) observed at month four was 92.2%. The median OS was not reached as of the data cutoff, with a median follow-up time of 5.65 months. The median progression-free survival (PFS) was 5.52 months with a median follow-up time of 5.65 months and a 4-month PFS rate of 78.2%. At evaluation, 31 (47%) of patients were still on treatment with the longest duration of treatment eclipsing one year (367 days).

The safety profile in PDAC patients was consistent with the previously reported data at recent medical congresses. As of the data cutoff date of August 27, 2025, the most frequent treatment-related adverse events (TRAEs) occurring in ≥20% of patients included diarrhea, neutrophil count decreased, vomiting, nausea, anemia, white blood cell count decreased, decreased appetite, hypoalbuminemia, platelet count decreased, asthenia, aspartate aminotransferase increased, and alanine transferase increased. Grade 3 TRAEs occurred in 20 patients (30.3%) and a Grade 4 TRAE (neutropenia) occurred in one patient (1.5%). Of the 66 patients in the safety population, four patients (6.1%) had a dose reduction and two patients (3%) discontinued due to TRAEs. No TRAE-related deaths were reported. The mean relative dose intensity was 93%.

About KRAS G12D

KRAS G12D represents 26% of all KRAS mutations, making it the most prevalent KRAS mutation in human cancers. The KRAS G12D mutation occurs most commonly in pancreatic (37%), colorectal (12.5%), endometrial (8%), and non-small cell lung (5%) cancers. Currently, no therapies are approved by the U.S. Food and Drug Administration (FDA) specifically targeting KRAS G12D mutations in cancer.

About VS-7375, an Oral KRAS G12D (ON/OFF) Inhibitor

VS-7375 is a potential best-in-class, potent, and selective oral KRAS G12D dual ON/OFF inhibitor. VS-7375 is the lead program from the Verastem Oncology discovery and development collaboration with GenFleet Therapeutics. Verastem announced in April 2025 that the U.S. Investigational New Drug (IND) application for VS-7375 was cleared and initiated a Phase 1/2a clinical trial in June 2025. GenFleet’s IND for VS-7375 (known as GFH375 in China) was approved in China in June 2024, and the first patient was dosed in a Phase 1/2 study in July 2024.

About the Phase 1/2a Study of VS-7375

The Phase 1/2a study will be conducted in the U.S., with the potential to expand globally, and will evaluate the safety and efficacy of VS-7375 in patients with advanced KRAS G12D mutant solid tumors. The starting dose for the Phase 1 study of 400 mg is based on the dose identified in the initial data from the GenFleet study to accelerate the trial’s progress. Verastem plans to dose escalate across levels where responses were observed in GenFleet’s study and will assess in the Phase 2a portion the efficacy and safety of VS-7375, both as monotherapy and in combination, in patients with advanced solid tumors, such as pancreatic, colorectal, and non-small cell lung cancers.
