The Breakthrough Therapy designation, introduced by the NMPA, is a key initiative aimed at accelerating the development and approval of innovative medicines that offer significant clinical benefits. With this designation, ATG-022 will receive priority review resources, reducing the overall research and development timeline and enabling faster access for patients in China. This follows the U.S. Food and Drug Administration’s (FDA) granting of Orphan Drug Designation (ODD) to ATG-022 for the treatment of gastric and pancreatic cancers, highlighting its strong clinical potential across multiple tumor types.

In the ongoing CLINCH Phase I/II clinical study, data show that ATG-022 demonstrated significant antitumor activity and a favorable safety profile in patients with gastric or gastroesophageal junction adenocarcinoma across high, low, and ultra-low CLDN18.2 expression levels.

CLDN18.2 Moderate-to-high expression (IHC 2+ > 20%)
2.4 mg/kg Cohort
Objective Response Rate (ORR): 40% (12/30), including 1 Complete Response (CR)
Disease Control Rate (DCR): 90% (27/30)
Median Progression-free Survival (mPFS): 6.97 months
6-month PFS Rate: 51.1%
9-month Overall Survival (OS) Rate: 82.7%
12-month OS Rate: 66.2%
1.8 mg/kg Cohort
ORR: 40% (10/25), including 1 CR
DCR: 84% (21/25)
CLDN18.2 Low and Ultra-low expression (IHC 2+ ≤ 20%)
Efficacious dose range of 1.8-2.4 mg/kg
ORR: 33.3% (6/18), including 1 CR
DCR: 50% (9/18)
Notably, some responding patients had CLDN18.2 expression levels below 5%, underscoring the robust antitumor activity of ATG-022 in both low- and ultra-low-expression populations.
To date, three patients in the study have achieved CR during treatment, with one case observed in each of the three aforementioned cohorts (i.e., both dose levels in the CLDN18.2 moderate-to-high expressor cohorts and the CLDN18.2 low and ultra-low expressor cohort). This broad-spectrum antitumor activity positions ATG-022 as a potential new treatment option for a wider patient population compared with other CLDN18.2-targeted therapies.

Antengene is currently conducting the Phase II dose-expansion stage of ATG-022 in the Mainland of China and Australia, with the program now entering mid-to-late stage of clinical validation. The company will continue to advance the clinical development of ATG-022 in gastric cancer while exploring its potential in other CLDN18.2-positive tumors. For gastric cancer indications, the development strategy spans first- through third-line treatment:

First-line treatment (CLDN18.2 IHC 1+ ≥1%, PD-L1 CPS ≥1%): ATG-022 in combination with pembrolizumab and chemotherapy (CAPOX/FOLFOX)
Second-line treatment (CLDN18.2 IHC 1+ ≥1%, PD-L1 CPS ≥1%): ATG-022 in combination with pembrolizumab
Third-line treatment (CLDN18.2 IHC 2+): ATG-022 monotherapy, covering patients across different CLDN18.2 expression levels, including CLDN18.2 moderate-to-high expressor (2+ >20%), and low and ultra-low expressors (2+ ≤20%)
In addition, the ongoing Phase II study includes a basket trial cohort covering multiple tumor types. In a certain subtype of gynecologic tumor, all 7 patients who had undergone at least one efficacy assessment demonstrated tumor shrinkage, indicating significant clinical potential for ATG-022 in other CLDN18.2-positive tumors. This cohort remains open for enrollment and follow-up, and the continued data generation is expected to further strengthen the robust value proposition of ATG-022 across multiple tumor types.

On August 19, 2025 ALX Oncology Holdings Inc., ("ALX Oncology" or the"Company") (Nasdaq: ALXO), a clinical-stage biotechnology company advancing a pipeline of novel therapies designed to treat cancer and extend patients’ lives, reported that the first patient has been dosed in the Company’s Phase 1 clinical trial for ALX2004, a potential best- and first-in-class, epidermal growth factor receptor (EGFR) ADC that is being studied for the treatment of EGFR-expressing solid tumors (Press release, ALX Oncology, AUG 19, 2025, View Source [SID1234655368]).

"Dosing of the first patient in the Phase 1 trial is an important milestone in ALX Oncology’s mission to develop a pipeline of best-in-class drugs; ALX2004 is our first ADC and treating our first patient with this drug is a significant step forward in fulfilling the potential of EGFR-targeted ADCs," said Jason Lettmann, Chief Executive Officer at ALX Oncology. "Our preclinical data supports our conviction that ALX2004, with its optimized antibody, linker and payload, has the potential to overcome the toxicity challenges that have limited earlier generation EGFR-targeted ADCs. We look forward to enrolling this trial and expect to report initial safety data in the first half of 2026."

The Phase 1 clinical trial (NCT07085091) is a first-in-human, open-label multicenter study evaluating ALX2004 in participants with advanced or metastatic select EGFR-expressing solid tumors. The study consists of a Phase 1a dose escalation portion followed by dose exploration, and a Phase 1b dose expansion. The dose escalation portion of the trial will enroll patients with previously treated advanced or metastatic non-small cell lung cancer (NSCLC), head and neck squamous cell carcinoma (HNSCC), esophageal squamous cell carcinoma (ESCC) and colorectal cancer (CRC). All or a subset of these tumor types may be included in the dose exploration and expansion portions of the trial.

ALX2004: Optimized for Success Based on Rigorous Drug Design Process

Developed by ALX Oncology’s protein engineers utilizing the Company’s proprietary topoisomerase I inhibitor (Top1i) payload and linker payload platform, ALX2004 is a uniquely designed EGFR-targeted ADC where every component is optimized to maximize the therapeutic window by reducing toxicity. This includes an affinity-tuned EGFR antibody with a binding epitope distinct from approved EGFR antibodies. ALX2004 also has a proprietary Top1i payload engineered to offer enhanced bystander effect with improved linker stability for on-target delivery of payload.

Robust Preclinical Data: Supporting Differentiation in EGFR-ADC Class

Preclinical data supports ALX2004’s differentiated linker-payload construct, which has demonstrated superior stability versus other ADCs in its class, with dose-dependent activity and a favorable safety profile. In addition, ALX2004 has shown dose-dependent activity across a range of tumors, EGFR expression levels and mutations. Potent activity in tumor models supports its potential for treating patients with EGFR-expressing tumors. Preclinical model findings did not demonstrate EGFR-related skin toxicity at clinically relevant doses or payload-related interstitial lung disease, supportive of a potentially differentiated safety profile.
