Akeso Unveils Promising Preclinical Data for IL-1RAP Targeting Antibody (AK135) at SITC 2025

On November 7, 2025 Akeso, Inc. (HKEX: 9926.HK) reported the preclinical research data for its novel antagonistic monoclonal antibody targeting IL-1RAP, AK135, at the 40th Annual Meeting of the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper) held in National Harbor, Maryland.

The results demonstrated that AK135 effectively targets IL-1RAP and blocks three key pro-inflammatory signaling pathways—IL-1, IL-33, and IL-36 at their source, thereby halting the transmission of inflammatory signals. In preclinical models, AK135 provided significant pain relief in neuropathy, exhibiting dose-dependent efficacy, while also showing good tolerability and safety profiles.

In vitro Results:

ELISA, Fortebio molecular interaction technology, and flow cytometry (FACS) results demonstrated that AK135 has high affinity for IL-1RAP, with binding activity comparable to or superior to that of the control antibody CAN04.
Reporter gene assays further confirmed that AK135 effectively inhibits the activation of IL-1, IL-33, and IL-36 signaling pathways, showing excellent half-maximal inhibitory concentration (IC50) values in each of the pathways.
In tumor cell models, AK135 significantly reduced the secretion of pro-inflammatory cytokines (such as IL-6 and IL-8) induced by IL-1, IL-33, and IL-36.
In vivo Results:

The in vitro experiments confirmed the high affinity and potent neutralizing activity of AK135. To further evaluate its in vivo efficacy, the research team established a Chemotherapy-induced peripheral neuropathy (CIPN) mouse model and assessed the pharmacological effects of AK135 through intermittent low-dose paclitaxel administration.
Following AK135 treatment, the paw withdrawal threshold (PWT) in the CIPN model was significantly increased, indicating that AK135 effectively alleviated mechanical allodynia, with a dose-dependent efficacy.
Throughout the treatment period, mice in all dose groups maintained stable body weight, with no significant signs of toxicity, demonstrating good tolerance.
CIPN is a prevalent and dose-limiting side effect of chemotherapy, affecting 50-90% of treated patients, of which 30-40% progressing to chronic neuropathic pain. Despite its clinical significance, effective treatment options remain limited, and the underlying mechanisms are not fully understood. Emerging evidence suggests that pro-inflammatory cytokines released by the damaged neurons play a key role in CIPN pathogenesis. IL-1 receptor accessory protein (IL-1RAP/IL-1RAcP) is a critical mediator of inflammatory signaling, amplifying responses through the interleukin-1 (IL-1), interleukin-33 (IL-33), and interleukin-36 (IL-36) pathways. Akeso developed AK135, a novel antagonistic monoclonal antibody targeting IL-1RAP, to alleviate the peripheral neuralgia by inhibiting these proinflammatory signaling pathways.

About AK135 (IL-1RAP Targeting Antibody)
AK135 is a novel antagonistic antibody targeting IL-1RAP, internally developed by Akeso, aimed at treating chemotherapy-induced peripheral neuropathy (CIPN). By precisely blocking IL-1RAP, this product simultaneously inhibits the three core inflammatory signaling pathways—IL-1, IL-33, and IL-36, providing relief from neuroinflammatory responses at their source. Preclinical studies have shown that AK135 significantly alleviates neuropathic pain in a dose-dependent manner, while also demonstrating good tolerance. Currently, AK135 is in Phase I clinical trials for the treatment of CIPN.

Ivonescimab HARMONi-A Study Final OS Analysis Results Presented at SITC 2025 with OS HR=0.74

On November 7, 2025 Akeso, Inc. (HKEX: 9926.HK) reported that the final Overall Survival (OS) analysis results from the HARMONi-A study, a Phase III study evaluating ivonescimab combined with chemotherapy for the treatment of EGFR-mutated non-squamous non-small cell lung cancer (nsq-NSCLC) following EGFR-TKI progression, were selected as a "Late-Breaking Abstract" (LBA) for the 40th Annual Meeting of the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper), held in National Harbor, Maryland, USA. Professor Xiuning Le from MD Anderson Cancer Center presented these findings to a global audience during an oral presentation session.

HARMONi-A is the first global Phase III clinical trial of an immunotherapy in the EGFR-TKI resistant, EGFR-mutated nsq-NSCLC setting to demonstrate clinically meaningful and statistically significant benefits in both Progression-Free Survival (PFS) and Overall Survival (OS). This final OS analysis, the first from a Phase III trial of ivonescimab, confirms the breakthrough value of ivonescimab-based therapy in improving both PFS and OS. Historically, cancer immunotherapies have largely failed to demonstrate significant breakthroughs in this specific indication. Prior Phase III trials involving other regimens—such as PD-1 inhibitors combined with chemotherapy or immunotherapies combined with anti-angiogenic therapy, failed to show significant OS benefits. The significant positive outcomes in both PFS and OS in the HARMONi-A study underscore the substantial clinical benefit improvement of ivonescimab over PD-1 inhibitors.

Previously, the HARMONi-A study had already met its primary endpoint, demonstrating a statistically significant improvement in PFS at the interim analysis (PFS HR 0.46, P < 0.001). Previously, during the regulatory review for the approval of ivonescimab in first-line PD-L1-positive NSCLC in China, a descriptive analysis of OS from the HARMONi-A study was conducted in May 2024 at the request of the regulatory authorities. The final OS analysis results presented at SITC (Free SITC Whitepaper) 2025 represent the final and only pre-specified formal OS analysis for the HARMONi-A study, performed as a sequential test according to the pre-specified statistical analysis plan (SAP).

The final OS analysis, with a median follow-up period of 32.5 months, showed that the ivonescimab plus chemotherapy regimen provided a clinically meaningful and statistically significant improvement in OS compared to chemotherapy alone:

The median OS was 16.8 months in the ivonescimab treatment group compared to 14.1 months in the control group (OS HR=0.74, P=0.019), achieving statistical significance. The OS benefit increased with extended follow-up.
The ivonescimab combination regimen consistently demonstrated OS benefit over the control group across all subgroups:
In patients with brain metastases, OS HR=0.61;
In patients without brain metastases, OS HR=0.77;
In patients with EGFR 19Del mutations, OS HR=0.83;
In patients with EGFR L858R mutations, OS HR=0.60.
With a median follow-up of 32.5 months, the long-term safety profile of the ivonescimab combination therapy remained favorable, with no new safety signals identified. The incidence of common treatment-related adverse events (TRAEs) showed no significant difference between the two groups.

Based on the positive clinical data from the HARMONi-A study, ivonescimab received approval from the China National Medical Products Administration in May 2024 for this indication. In November 2024, Akeso announced that ivonescimab was successfully added to China’s National Reimbursement Drug List, effective January 1, 2025, ensuring widespread patient access to this life-saving treatment.

Additionally, Summit Therapeutics, Akeso’s global partner for ivonescimab, announced in October 2025 that it plans to submit a Biologics License Application (BLA) to the U.S. Food and Drug Administration (FDA) in the fourth quarter of 2025, seeking approval for ivonescimab in combination with chemotherapy for the treatment of EGFR-mutant, third-generation EGFR-TKI-resistant, non-squamous NSCLC.

CREATE Medicines Announces Positive First-in-Human Results for MT-302

On November 7, 2025 CREATE Medicines Inc. (formerly Myeloid Therapeutics), a biotechnology company advancing in vivo immune-cell programming with mRNA-LNP therapeutics, reported first-in-human results from its Phase 1 MYE Symphony trial (NCT05969041) evaluating MT-302, an mRNA-LNP-encoded TROP2-targeted in vivo CAR therapy in patients with advanced solid tumors, at the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper) 40th Anniversary Annual Meeting.

"These data provide important mechanistic insights into how in vivo programmed myeloid cells behave within the tumor microenvironment," said Rasha Cosman BSc (Med), MBBS, FRACP, Head of the Early Phase Clinical Trials Unit at The Kinghorn Cancer Centre, St. Vincents Hospital Sydney, "The degree of remodeling observed, combined with a manageable safety profile and repeat-dose feasibility, and early signal of anti-tumor activity in a heavily pre-treated population, is highly encouraging in tumor settings where immune infiltration has been historically limited. Seeing immune cells effectively reprogrammed inside the body to mount a targeted anti-tumor response represents a meaningful milestone and supports continued clinical advancement."

Results
27 patients with advanced TROP2-positive solid tumors were treated with MT-302 across seven dose cohorts.

Manageable safety profile consistent with immune cell activation.
Dose and tumor burden dependent low grade cytokine release syndrome observed in 51.9% of participants with kinetics consistent with tumor target engagement. There were no events of grade 3 or higher CRS.
Maximum tolerated dose: 0.10 mg/kg without steroid premedication. One Grade 4 ICANS event was observed at the highest dose tested (0.15 mg/kg).
Pharmacokinetics: terminal half-life of pegylated and ionizable lipids 45–50 hours.
Biological activity: CAR⁺ myeloid cells observed within tumors with T-cell infiltration and cytokine induction (IFNγ, CXCL9/10); the CXCL9:SPP1 ratio correlated with tumor-burden change, indicating pro-inflammatory tumor-microenvironment remodeling.
Clinical signal: one confirmed partial response in HR⁺ breast cancer in a patient on treatment for 16 months (20 doses) with pharmacological activity observed at 0.015 mg/kg.
"These data represent the first demonstration of an in vivo CAR therapy achieving tumor penetration and measurable biological activity in patients with solid tumors," said Matt Maurer, MD, Chief Medical Officer of CREATE Medicines. "MT-302 showed proof-of-mechanism while maintaining a manageable safety profile and repeat dosing without preconditioning or immunosuppression."

Conclusions
In this first-in-human study, MT-302 demonstrated tolerable repeat dosing, robust immunologic activity, direct tumor penetration by CAR myeloid cells and broad immune activation in heavily pre-treated patients. These results provide clear proof-of-mechanism for in vivo CAR therapies in solid tumors and support advancement of MT-302 for front-line use. Dosing with MT-302 was recently initiated in the first ever front-line solid tumor trial with an in vivo CAR combined with a standard frontline regimen in the SPaCE-MT trial (EUCT 2024-520213-45-00).

"This is a foundational moment for our platform and for the field of in vivo cell therapy," added Daniel Getts PhD, Chief Executive Officer and co-founder of CREATE Medicines. "We have clinical evidence demonstrating that immune cells can be reprogrammed inside the body to mount a targeted anti-tumor response, paving the way for a new, highly versatile modality in the fight against solid tumors."

About MT-302
MT-302 is an investigational mRNA-LNP in vivo CAR therapy designed to program immune cells inside the body. Delivered systemically, MT-302 recognizes and eliminates TROP2-expressing solid tumors by encoding a TROP2-specific chimeric antigen receptor to transiently reprogram immune cells. This approach eliminates the need for ex vivo manipulation or preconditioning, while achieving repeatable dosing and controllable anti-tumor activity.
