Antengene Announces 2024 Full-Year Financial Results, Proprietary Programs Advancing to Pivotal Trials with Accelerating Multi-market Revenue Ramp Up
SHANGHAI and HONG KONG, March 21, 2025 /PRNewswire/ -- Antengene Corporation Limited ("Antengene", SEHK: 6996.HK) today announced its full-year results for the period ending December 31, 2024, along with several significant milestones achieved in recent months.
Dr. Jay Mei, Antengene's Founder, Chairman, and CEO, stated, "To Antengene, 2024 was indeed an extraordinary year in which we achieved remarkable progress on multiple fronts, including clinical development, R&D and commercialization. ATG-022, our Claudin 18.2 antibody-drug conjugate that is being evaluated in a Phase II study in Australia and China, has shown highly differentiated clinical potential, demonstrating efficacy not only in gastric cancer patients with mid to high Claudin 18.2 expressions, but also unprecedented clinical benefit for patients with low or ultra-low expressions. Furthermore, AnTenGager(TM) TCE 2.0, Antengene's proprietary platform incorporating steric hindrance-masking technology, has shown impressive capabilities, with its preclinical data demonstrating a significantly more favorable safety profile than those of the first-generation TCE platforms, and potential clinical efficacy covering solid tumors, hematologic malignancies and autoimmune diseases. We will seek various forms of collaboration with global partners around this technology platform in order to fully unlock its potential value. ATG-201, a CD19 x CD3 TCE 2.0 developed on the AnTenGage(TM) TCE 2.0, is poised to enter clinical development in the second half of 2025.
In addition to the rapid progress in R&D and clinical development, we also achieved impressive results in commercialization. Our first approved product, XPOVIO(®), has clearly picked up momentum in its global expansion while having its second indication approved and included in the NRDL in China. Also during the reporting period, XPOVIO(®) was included for reimbursement in South Korea and Taiwan China, and approved for commercialization in Malaysia, Thailand, and Indonesia. To date, XPOVIO(®) has been approved in 10 APAC markets and included for reimbursement coverage in 5 of those markets. Currently, the company has a cash reserve of RMB 900 million which is sufficient to fund its continued operations over the next three years even without future revenue income. We look forward to updating you all on our progress in 2025, with the next one being the latest results on the AnTenGage(TM) TCE 2.0, scheduled for release at this year's AACR Annual Meeting."
1. Claudin 18.2 ADC Demonstrates Significant Clinical Value, with Multiple Programs Advancing Steadily at the Clinical Stage
-- ATG-022?Claudin 18.2 Antibody-Drug Conjugate, ADC?
-- Unique Therapeutic Potential: ATG-022 is a highly differentiated ADC
demonstrated efficacy across the broadest range of CLDN18.2
expression levels. Clinical data show that ATG-022 not only
effectively targets gastric cancer patients with high CLDN18.2
expression but is also effective in tumors with low and ultra-low
CLDN18.2 expression. Additionally, ATG-022 has shown better safety
profile without accumulative systemic toxicities, and much fewer
dose-limiting toxicities and lower high grade adverse effects
compared to other CLDN 18.2 ADCs in similar clinical development
stages. It also has received two Orphan Drug Designations (ODDs)
from the U.S. Food and Drug Administration (FDA) for the treatment
of gastric and pancreatic cancer.
-- Ongoing CLINCH study: As of November 22, 2024, among 21 gastric
cancer patients in the dose expansion phase with CLDN18.2 expression
at IHC 2+ >= 20% achieved an Objective Response Rate (ORR) of 42.9%
and a Disease Control Rate (DCR) of 95.2% (9 patients had Partial
Responses [PR], 8 of which were confirmed; 11 patients had Stable
Disease [SD]). Additionally, 10 patients with CLDN18.2 expression at
IHC 2+ < 20% treated at efficacious doses of 1.8 - 2.4 mg/kg had an
ORR of 30.0% (1 patient achieved a Complete Response [CR], 2
achieved PR, and all confirmed CR/PR cases had CLDN18.2 expression
IHC 2+ < 5%), with a DCR of 50.0%. The patient who achieved a CR has
demonstrated sustained remission and has been in the study for over
14 months as of the data cut-off date. The Phase II CLINCH study is
progressing smoothly in China and Australia.
-- Other Clinical Stage Programs
-- ATG-037 (CD73 Small Molecule Inhibitor): ATG-037 has demonstrated
pre-clinically the ability to overcome the "hook effect" that can
limit efficacy and is commonly seen in anti-CD73 antibodies.
Antengene entered into a global clinical collaboration with MSD and
is currently evaluating this molecule in combination with the
anti-PD-1 therapy, KEYTRUDA(®) (pembrolizumab), in patients with
anti-PD-1 resistant melanoma and non-small cell lung cancer (NSCLC).
At the 2024 European Society of Medical Oncology (ESMO) Congress,
clinical data from the ongoing Phase I STAMINA dose-escalation study
were presented in a Mini Oral session. As of the latest data cut-off
date on November 27, 2024, among the 26 evaluable patients with
prior anti-PD-1 resistance who received ATG-037 in combination with
pembrolizumab, 9 had NSCLC and 11 had melanoma. Among these
patients, the ORR is 35% and DCR is 85%. These data indicate that
ATG-037 has the potential to reverse anti-PD-1 resistance during the
dose-escalation phase. Currently, the Phase II STAMINA dose
optimization and expansion study is progressing smoothly in China
and Australia.
-- ATG-031 (Anti-CD24 Monoclonal Antibody): ATG-031 is the
first-in-class humanized anti-CD24 monoclonal antibody to enter
clinical trials for cancer in the U.S. ATG-031 works by blocking
CD24-Siglec10 and enhancing macrophage-mediated phagocytosis of
cancer cells. Key study sites of ATG-031 include four renowned
cancer centers in the United States: MD Anderson Cancer Center at
the University of Texas, University of California, San Francisco
(UCSF), University of Colorado, and Yale Cancer Center. The Phase I
PERFORM study is progressing smoothly in the U.S.
2. The Exciting Proprietary AnTenGager(TM) TCE 2.0 with Steric Hindrance-masking Technology
-- Next-Generation TCE Platform: The AnTenGager(TM) TCE 2.0 is Antengene's
proprietary "2+1" TCE platform which features a steric hindrance-masking
technology designed to enable disease-associated antigen (DAA)-dependent
T-cell activation. This approach is intended to achieve potent
therapeutic activity while reducing the risk of cytokine release
syndrome (CRS). Compared to first-generation TCE platforms,
AnTenGager(TM) TCE 2.0 offers better safety and has broader
applicability in different indications such as in solid tumors,
hematological malignancies, and autoimmune diseases. Additionally,
AnTenGager(TM) TCE 2.0 has a longer half-life, which allows for reduced
dosing frequency and improved clinical convenience. The company will
continue to advance the development of AnTenGager(TM) TCEs.
-- Global Collaborations: Antengene will seek a range of collaborations
with its global partners for the AnTenGage(TM) TCE 2.0, through platform
access, co-development, and out-licensing, in order to enable the
accelerated development of an ecosystem around TCE therapeutics and
maximize the value of the technology platform.
-- ATG-201 (CD19 x CD3 TCE 2.0): ATG-201 is a novel "2+1" CD19-targeted
T-cell engager developed using the AnTenGager(TM) TCE 2.0 for the
treatment of B cell related autoimmune diseases. In preclinical studies,
ATG-201 demonstrated superior B-cell depletion compared to benchmark
molecules, along with reduced cytokine release. The company expects
ATG-201 to enter clinical development in the second half of 2025.
-- Antengene will continue to advance other preclinical programs, including
ATG-042 (a selective PRMT5 inhibiting targeting MTAP-null tumors),
ATG-106 (CDH6 x CD3 TCE 2.0) for ovarian and renal cancer, and ATG-110
(LY6G6D x CD3 TCE 2.0) for microsatellite stable (MSS) colorectal
cancer.
3. Accelerating Global Expansion: Covering 10 APAC Markets
-- Mainland of China: In July 2024, XPOVIO(®) received approval for a
second indication in Mainland China, providing a new treatment option
for Chinese DLBCL patients. In November 2024, this indication was
included in the National Reimbursement Drug List (NRDL). As of now, both
approved indications of XPOVIO(®) in China are covered under national
insurance, further expanding patient access.
-- South Korea: In June 2024, XPOVIO(®) received national reimbursement
approval in Korea, effective from July 1, 2024. In October 2024,
XPOVIO(®) was approved for an additional third indication in Korea. The
company is actively working to expand reimbursement coverage for more
indications in Korea.
-- Taiwan Market: In February 2025, XPOVIO(®) received national
reimbursement approval in Taiwan market, making it the fifth APAC market
to secure reimbursement coverage after mainland of China, South Korea,
Australia, and Singapore.
-- ASEAN Markets: Since August 2024, XPOVIO(®) has been successively
approved in Malaysia, Thailand, and Indonesia, marking significant
progress in Antengene's commercialization strategy across the APAC
region. XPOVIO(®) is now approved in 10 countries and regions across
APAC for multiple indications.
4. Strong Cash Reserves to Support Continuous Growth
As of December 31, 2024, the company held RMB 900 million in cash and bank balances, which is sufficient to fund the company's continuous growth and operations over the next three years even without additional financing.
