Anixa’s breast cancer vaccine, developed in collaboration with Cleveland Clinic, represents a novel approach to the prevention and treatment of breast cancer. Anixa’s vaccine is based on immunizing against human α-lactalbumin, a protein associated with lactation that is aberrantly expressed in certain types of breast cancer. This "retired" protein vaccine strategy aims to selectively prime the immune system to prevent tumor formation while avoiding harm to normal tissue. The vaccine was invented at Cleveland Clinic, and this patent—along with others related to this technology—has been exclusively licensed to Anixa Biosciences.

This patent issuance builds upon the Company’s broad and expanding intellectual property portfolio, extending foundational patent protection for the breast cancer vaccine program into the 2040s in multiple jurisdictions throughout the world. By reinforcing its global patent estate, Anixa is laying the groundwork for future international development and commercialization strategies.

"This newly issued patent further demonstrates the novelty and potential of our breast cancer vaccine," stated Dr. Amit Kumar, Chairman and CEO of Anixa Biosciences. "As we continue advancing clinical development in the U.S., this patent further strengthens our ability to pursue strategic global opportunities in regions with a high incidence of breast cancer."

A Phase 1 clinical trial of Anixa’s breast cancer vaccine has been recently completed and Cleveland Clinic will present full clinical results at the San Antonio Breast Cancer Symposium on December 11, 2025.

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.

134 patients were enrolled across sites in the UK and Germany. Median age was 62 years and nearly half had received three or more prior therapies. The combination achieved mean progression-free survival (PFS) of 5.8 months compared to 4.0 months with paclitaxel alone, extending time to disease progress by approximately 45 percent. The addition of sapanisertib was associated with a 34% reduction in risk of progression compared to paclitaxel alone (HR=0.66; 90% CI: 0.45–0.96; p=0.07), meeting the trial’s prespecified hazard ratio target of 0.66.

Grade 3/4 adverse events occurred in 7% of patients receiving the combination versus 6.6% for paclitaxel alone. Gastrointestinal toxicities (11.4% vs. 0%) and rash (2.9% vs. 0%) were more common with the combination but were manageable.

"Platinum-resistant ovarian cancer remains one of the toughest conditions we face, with women often cycling through treatments that only briefly hold the disease at bay temporarily," said Jonathan Krell, MD, Ovarian Cancer Action Research Centre, Imperial College London, the study’s lead investigator. "The DICE trial shows that adding an oral targeted agent to weekly paclitaxel can slow progression without added high-grade toxicity, a finding that clearly warrants a phase 3 trial."

"These results reinforce our belief that targeting the metabolism of cancer cells can improve the impact of existing therapies," said Anand Parikh, JD, CEO and co-founder of Faeth Therapeutics. "On the strength of DICE, we see sapanisertib plus paclitaxel as phase 3-ready in ovarian cancer, alongside our ongoing phase 2 in endometrial cancer and planned phase 1b/2 in breast cancer."

Response rate and overall survival analyses are ongoing. The trial is also evaluating biomarkers, including PTEN expression, metabolic signatures, and genomic correlates, to identify patients most likely to benefit from the combination.

About the DICE Trial

DICE (NCT03648489) is a multi-centre randomized phase 2 study comparing weekly paclitaxel alone versus paclitaxel plus sapanisertib in women with platinum-resistant or recurrent ovarian or fallopian tube cancer. The primary endpoint is progression-free survival; secondary endpoints include response rate and overall survival. Translational endpoints include PTEN correlation and exploratory biomarker analyses.

Resistance to Immune Checkpoint Inhibitors (ICI) remains a major challenge in the treatment of solid tumors such as non-small cell lung cancer (NSCLC) and head and neck squamous cell carcinoma (HNSCC). Netrin-1, an embryonic guidance factor re-expressed in various cancers, contributes to tumor resistance and epithelial-to- mesenchymal transition (EMT). NP137, a first-in-class monoclonal antibody targeting Netrin-1, has demonstrated the ability to inhibit EMT and modulate the tumor microenvironment, thereby potentially restoring sensitivity to immunotherapy.

IMMUNONET (NCT05605496) was designed to evaluate whether NP137 was able to (re)-sensitize solid tumors to ICI. Patients who had progressed under a prior anti–PD-1/PD-L1 were enrolled to receive NP137 as an add–on to their immunotherapy. They were enrolled in 3 distinct cohorts depending on their best response and time to progression (cohort 1, stable disease; cohort 2, primary refractory and cohort 3, secondary refractory). The study was designed as a 2-stage adaptive design. This poster reports the results of stage 1. In cohort 3 (secondary refractory) where a majority of NSCLC and HNSCC patients were enrolled, the primary endpoint of Progression-Free Rate at 12 weeks (PFR-12W) was met ahead of stage 2. These results strongly suggest the efficacy of combining NP137 with anti–PD-1/PD-L1 therapy in this difficult-to-treat population and warrant further controlled studies to confirm these findings.

Importantly, the combination of NP137 with ICI was very well tolerated. « These preliminary results are particularly encouraging » said Dr Jérome Fayette, M.D., Ph.D., Principal Investigator of the study. « Patients who have progressed after prior anti–PD-1/PD-L1 therapy represent one of the most difficult populations to treat. The encouraging efficacy and safety results observed in this study strongly support the continued clinical development of NP137. Advancing to a confirmatory randomized study will allow to further validate these findings and better define the therapeuticpotential of NP137 in combination with immune checkpoint inhibitors for patients with advanced solid tumors ».

« Observing durable disease control in this setting supports the concept that targeting Netrin-1 can re-sensitize tumors to immune checkpoint inhibition » added Dr. Sébastien Hazard, Chief Medical Officer of NETRIS Pharma. « Combining NP137 with checkpoint inhibitors may offer a new option for patients who no longer benefit from standard immunotherapy ».

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.
