AT03-65 is a differentiated ADC that selectively binds to CLDN6 with strong affinity. It is enabled by AxcynDOT, a proprietary payload that incorporates a derivative of an approved oncology therapeutics with unique mechanism of action and broad anti-tumor activity, and coupled with a cleavable and hydrophilic proprietary linker. CLDN6 is overexpressed in many cancers including lung, ovarian, endometrial, uterine, testicular, and gastric cancers while exhibiting minimal expression in normal tissues. AT03-65 is designed to deliver targeted therapy to improve patient outcomes with advanced or metastatic CLDN6-positive cancers.

"This is a transformational event for Axcynsis and a significant milestone for our proprietary ADC platform using AxcynDOT," said Dr. Zou Bin, CEO of Axcynsis. "We are pleased that FDA has cleared AT03-65 which leverages our AxcynDOT technology for this first-in-human study. We are very excited with the potential of offering a transformative therapeutic option for patients with CLDN6-positive tumors as well as advancing our pipeline with differentiated and effective ADCs using AxcynDOT to improve the lives of cancer patients worldwide".

The upcoming Phase 1 multicentre clinical trial in the United States will evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics and preliminary efficacy of AT03-65 in patients with advanced CLDN6-positive solid tumors.

About AT03-65

AT03-65 is a recombinant anti-CLDN6 monoclonal antibody conjugated to AxcynDOT, a proprietary payload developed by Axcynsis with a differentiated mechanism of action and broad anti-cancer activities. AT03-65 is designed to target advanced, recurrent, or metastatic CLDN6+ solid tumors in patients who have progressed on or after standard systemic treatment or for whom no standard therapies are available.

The antibody of AT03-65 is rationally engineered for high affinity and specificity to CLDN6. Upon binding to CLDN6-expressing tumor cells, the ADC is internalized into lysosomes, where it releases its payload to inhibit tumor growth effectively. Preclinical studies demonstrate that AT03-65 not only directly kill CLDN6-positive tumor cells but also exhibits bystander killing effect, targeting neighboring CLDN6-negative tumor cells to enhance its anti-tumor efficacy. AT03-65 has demonstrated promising anti-tumor activities in multiple tumor mouse models and a favorable safety profile in non-human primates.

About AxcynDOT

This is a proprietary payload developed by Axcynsis. It is a derivative of trabectedin, an approved chemotherapy in the United States, Europe and selected Asian countries, with a unique mechanism of action that is differentiated from other DNA alkylating payloads. AxcynDOT is optimized with enhanced potency and improved safety profile compared to trabectedin.

To date, commercial and governmental insurance cover over 240 million lives for ANKTIVA.

About ANKTIVA

The cytokine interleukin-15 (IL-15) plays a crucial role in the immune system by affecting the development, maintenance, and function of key immune cells—NK and CD8+ killer T cells—that are involved in killing cancer cells. By activating NK cells, ANKTIVA overcomes the tumor escape phase of clones resistant to T cells and restores memory T cell activity with resultant prolonged duration of complete response.

ANKTIVA is a first-in-class IL-15 receptor agonist IgG1 fusion complex, consisting of an IL-15 mutant (IL-15N72D) fused with an IL-15 receptor alpha, which binds with high affinity to IL-15 receptors on NK, CD4+, and CD8+ T cells. This fusion complex of ANKTIVA mimics the natural biological properties of the membrane-bound IL-15 receptor alpha, delivering IL-15 by dendritic cells and drives the activation and proliferation of NK cells with the generation of memory killer T cells that have retained immune memory against these tumor clones. The proliferation of the trifecta of these immune killing cells and the activation of trained immune memory results in immunogenic cell death, inducing a state of equilibrium with durable complete responses. ANKTIVA has improved pharmacokinetic properties, longer persistence in lymphoid tissues, and enhanced anti-tumor activity compared to native, non-complexed IL-15 in-vivo.

On January 15, 2025 ImmunityBio, Inc. (NASDAQ: IBRX), a leading immunotherapy company, reported significant progress in its ongoing discussions with the U.S. Food and Drug Administration (FDA) regarding three areas of its clinical development pipeline in non-muscle invasive bladder cancer (NMIBC) and non-small cell lung cancer (NSCLC) (Press release, ImmunityBio, JAN 15, 2025, View Source [SID1234649739]).

NMIBC BCG Unresponsive Papillary Disease: ImmunityBio is preparing to submit a supplemental Biologics License Application (sBLA) in 2025 for its innovative treatment targeting Bacillus Calmette-Guérin (BCG) unresponsive non-muscle invasive bladder cancer (NMIBC) in the papillary indication. As published in the Chamie 2022 NEJM1 publication, the primary endpoint was met with a disease-free rate of 55% at 12 months, 51% at 18 months, and 48% at 24 months. In addition, patients receiving ANKTIVA + BCG achieved a 93% avoidance of cystectomy with a median follow up of 20.7 months. This immunotherapy of rescuing BCG with ANKTIVA (nogapendekin alfa inbakicept-pmln), now approved in the CIS indication, represents a step towards providing therapeutic options in patients with BCG unresponsive NMIBC in papillary disease who currently have limited treatment choices and face radical total cystectomy (removal of bladder). The addition of the papillary indication could expand the potential patient population benefiting from this therapy and may allow patients to avoid the high morbidity and mortality associated with radical total cystectomy.

Alternative Source of BCG: In collaboration with the Serum Institute of India, ImmunityBio plans a regulatory submission for an alternative source of BCG in the first quarter of 2025. Serum Institute’s GMP capacity to manufacture large-scale volumes of BCG, already tested for safety and efficacy in clinical trials in Europe in subjects with NMIBC, aims to address the shortage of BCG, ensuring a reliable supply for patients in need. This initiative underscores ImmunityBio’s commitment to addressing critical supply issues and expanding the opportunity for patients and physicians to have access to high quality and quantities of BCG to initialize and maintain treatments for bladder cancer, subject to regulatory approvals.

Second-Line and Third-Line NSCLC Patients Who Have Progressed on Checkpoint Inhibitors: A Phase 2b study (QUILT-3.055) included (N=86) NSCLC patients and demonstrated prolonged overall survival when ANKTIVA was combined with the same checkpoint inhibitors on which patients were progressing, validating the rescue potential of ANKTIVA for T cells and checkpoint inhibitors. Compared to the most frequently used chemotherapy docetaxel in this setting with overall survival ranging from 7 to 10 months and associated with high toxicities of this chemotherapeutic agent, ANKTIVA plus a checkpoint inhibitor represents an immunotherapeutic advance for this disease.

ImmunityBio plans to submit a Biologics License Application (BLA) in 2025 for second- and third-line treatment of patients with NSCLC, who are progressing on checkpoint inhibitors. As presented at the IASLC 2024 World Conference on Lung Cancer by Dr. Wrangle2, the QUILT-3.055 study (Phase 2b, N=86) has shown promising results demonstrating a median overall survival for all patients at 14.1 months. In PD-L1 negative subjects, the median overall survival extended to 15.8 months.

"The potential to improve outcomes for NSCLC patients who have already relapsed on checkpoints is an unmet need. The combination of administering ANKTIVA plus a checkpoint even after checkpoint relapse/refractory represents a large potential for ANKTIVA to rescue checkpoint failure and prolong overall survival without the toxicities of chemotherapy," said Dr. Patrick Soon-Shiong, Executive Chairman and Global Chief Medical and Scientific Officer of ImmunityBio. "This submission underscores ImmunityBio’s dedication to advancing cancer treatment and providing new hope for patients battling this aggressive disease. This BLA submission together with our randomized ResQ201A-NSCLC (NCT06745908) Phase 3 trial in NSCLC is a potential stepping stone towards advancing novel immunotherapies in this indication for patients who have failed checkpoint inhibitor therapy."
