IBI354 has demonstrated promising anti-tumor efficacy and favorable safety profiles across multiple solid tumors. It not only holds potential to deliver a new generation of ADC therapies characterized by "high potency and low-toxicity" for tumor types such as ovarian cancer and breast cancer, but also validates the advantages of Innovent’s ADC technology platform. The results of IBI354 lays the foundation for the subsequent development of Innovent’s next-generation of bispecific ADCs and dual-payload ADCs, marking a milestone in Innovent’s next-generation "IO+ADC" oncology development strategy.

The data presented is from a Phase 1/2 clinical study (NCT05636215) aimed at evaluating the safety, tolerability, and preliminary efficacy of IBI354 in participants with advanced solid tumors. As of March 24, 2025, a total of 368 participants with advanced solid tumors were enrolled and received different doses of IBI354 monotherapy, the median follow-up duration was 11.5 months (range: 0.7-19.6), the median treatment duration was 27.0 weeks (range: 3.1-81.3) and 74 (20.1%) pts were still on treatment. The tumor types including 178 with breast cancer, 92 with ovarian cancer, 38 with colorectal cancer, and 60 with other tumors.

IBI354 monotherapy demonstrated excellent safety profile

The dosage was escalated to 18mg/kg, with no DLT events observed.
The most common treatment-related adverse events (TRAEs) were anemia, nausea, and white blood cell count decreased. The incidence of interstitial lung disease (ILD) was only 1.9%, all were grade 1-2.
Overall, 27.4% of patients experienced TRAEs ≥ grade 3, 17.7% experienced TRAEs leading to dose interruption, 2.7% experienced TRAEs leading to dose reduction and 1.6% experienced TRAEs leading to discontinuation, with no TRAEs leading to death.
IBI354 monotherapy showed promising efficacy signals in multiple tumor types

In HER2-positive breast cancer cohort (n= 88, treated at 6~15mg/kg, the median prior treatment lines was 4), the confirmed objective response rate (ORR) and the disease control rate (DCR) were 59.1% and 90.9%, respectively. In 9 mg/kg Q3W subgroup (n=29), the ORR and the DCR were 72.4% and 89.7%, respectively. The median progression-free survival (PFS) was 14.1 months (95% CI: 8.3-not calculable [NC]) with events of 48.3%. The median overall survival (OS) was immature with events of 3.4%.
In ovarian cancer cohort (n=92, treated at 2~12mg/kg, the median prior treatment lines was 3), the cORR was 41.2% and the DCR was 82.0%. In the 12mg/kg Q3W subgroup (n=40), the cORR reached 55.0% and the DCR was 90.0%. In participants with HER2 1+ (n=27), the ORR reached 55.6% and the DCR was 88.9%. As of the data cutoff date, the median follow-up time was 11.9 months, and the median PFS was 7.1 months (95% CI: 5.2−10.8) in 12mg/kg Q3W dose group. The median OS was not mature with events in 14 (34.1%) pts and a 12-month OS rate of 63.9% (95% CI: 45.0−77.8).
Professor Qi Zhou, Chief Physician at the Gynecologic Oncology Center of Chongqing University Affiliated Cancer Hospital and the Principal Investigator of the gynecologic oncology cohort study, stated, "The treatment of platinum-resistant recurrent ovarian cancer is difficult and the prognosis is poor, threatening the life and health of women. Extending PFS and OS in platinum-resistant recurrent ovarian cancer patients remains a clinical challenge for gynecological oncologists. ADC drugs provide a new direction for overcoming resistance mechanisms by precisely delivering cytotoxic agents. HER2, as a validated solid tumor target, has made breakthroughs in breast and gastric cancer fields, while the novel ADC drug IBI354 shows broad-spectrum antitumor activity through unique design in HER2 low-expression (IHC 1+) platinum-resistant ovarian cancer. In the Phase 1 study with a dose of 12mg/kg Q3W, IBI354 demonstrated an ORR of 55.0% and DCR of 90.0%, with a median PFS reaching 7.1 months. The safety profile was very good without common severe interstitial lung disease or ocular toxicity seen in other ADCs. These results significantly outperform traditional chemotherapy regimens, suggesting its potential breakthrough efficacy in the platinum-resistant population. The Phase 3 study of IBI354 in platinum-resistant ovarian cancer (HeriCare-Ovarian01) has been initiated, and I am looking forward to the results, as well as the further validation of the long-term benefits for patients receiving IBI354."

Doctor Charlotte Rose Lemech from Scientia Clinical Research Ltd, Australia, stated: "Breast cancer is one of the most common malignant tumors among women globally and remains a leading cause of cancer-related deaths. The amplification or overexpression of HER2 (human epidermal growth factor receptor 2) is recognized as a key driver in the development, progression, and metastasis of breast cancer, with approximately 15%-20% of breast cancer patients exhibiting HER2 overexpression. ADCs have become the new standard treatment for later line HER2 positive breast cancer. In this Phase 1 study, IBI354 has demonstrated encouraging efficacy and safety data, achieving high ORR and DCR especially in 9 mg/kg Q3W subgroup. Long term survival was also achieved with the median PFS of 14.1 months. IBI354 also differentiates itself from other HER2 targeted therapies with its safety profile. The incidence of interstitial lung disease was extremely low and most of the hematological toxicity and gastrointestinal adverse events were mild to moderate and can be effectively managed with standard supportive care. This favorable safety profile enhances the clinical application potential of IBI354 and we look forward to IBI354 achieving more breakthroughs in the field of breast cancer treatment."

Dr. Hui Zhou, Senior Vice President of Innovent, stated: "With the rapid development of ADC drugs in the field of tumor treatment, Innovent is steadily advancing its strategic layout in the ADC field. At this year’s ASCO (Free ASCO Whitepaper) conference, we update the safety and efficacy data of IBI354 across various advanced solid tumors. These clinical results not only confirm the potential therapeutic value of IBI354 but also demonstrating Innovent’s innovative strength and technological advantages in ADC drug development. The phase 3 study of IBI354 in platinum-resistant ovarian cancer has been initiated, and more clinical studies are also planned. We will continue to invest in next-generation ADC molecules, aiming to address unmet clinical needs and bring patients with more effective and safer treatment options."

New Data Shows NeXT Personal® Identifies Breast Cancer Patients Receiving Neoadjuvant Therapy that are at High Risk for Relapse

On June 2, 2025 Personalis, Inc. (Nasdaq: PSNL), a leader in advanced genomics for precision oncology, reported the presentation of new clinical results from the PREDICT DNA and SCANDARE studies highlighting the capabilities of its ultrasensitive NeXT Personal circulating tumor DNA (ctDNA) blood test for monitoring and predicting neoadjuvant therapy (NAT) response in triple negative breast cancer (TNBC), one of the most aggressive types of breast cancer (Press release, Personalis, JUN 2, 2025, View Source [SID1234653652]).

"Many triple negative breast cancer patients receive neoadjuvant therapy prior to surgery as standard of care. The data from these two studies independently suggest that an ultrasensitive ctDNA assay like NeXT Personal could help these patients better understand their risk of relapse, with the potential to help inform the need for additional therapy," said Richard Chen, MD, Chief Medical Officer and Executive Vice President, R&D at Personalis. "We believe this data, once published, can form the basis for seeking reimbursement coverage for neoadjuvant therapy monitoring in breast cancer. We are excited to continue to work with leading collaborators to expand the data around the use of NeXT Personal in breast cancer with the goal of helping breast cancer patients optimize their care."

Results from the PREDICT DNA study were presented yesterday by Dr. Natasha Hunter, MD, University of Washington, at the American Society for Clinical Oncology (ASCO) (Free ASCO Whitepaper) 2025 Annual Meeting in Chicago in an oral presentation titled "Circulating tumor DNA, pathologic response after neoadjuvant therapy, and survival: First results from TBCRC 040 (the PREDICT DNA trial)."

"The PREDICT DNA study prospectively evaluated ctDNA in early-stage patients with HER2-positive and triple negative breast cancer. The trial was initiated a decade ago and accrued 228 patients across 22 sites in the United States, and was statistically designed and powered for analysis of ctDNA to predict for pathologic complete response (pCR), and whether ctDNA could be a prognostic test to identify patients at high vs. very low risk for recurrence," said Dr. Ben Park, MD PhD, Vanderbilt-Ingram Cancer Center. "We partnered with Personalis because of their technology’s ultrasensitive detection of ctDNA down to 1 to 3 parts per million. Our results demonstrate that patients who ‘clear’ their ctDNA after upfront chemotherapy have excellent outcomes that mirror those with pCR, identifying a group of patients who, despite having residual disease at the time of surgery, will be at extremely low risk for recurrence. Conversely, those with detectable ctDNA after upfront chemotherapy are at a much higher risk of recurrence, and serial ctDNA measurements after surgery can help identify patients who may benefit from either escalation or de-escalation of therapies. We are truly excited by these results as they will allow us to more precisely risk-stratify patients with breast cancer in future trials and clinical practice."

Key findings included:

ctDNA status after completion of NAT (post-NAT) was highly prognostic for relapse-free survival (RFS).
Patients with ctDNA detected post-NAT were ~10 times more likely to relapse than patients who were ctDNA negative.
Detection of ctDNA post-NAT was more predictive of recurrence than pCR.
Patients who did not have detectable post-NAT ctDNA had excellent outcomes regardless of pathologic response.
Preliminary analyses indicate that patients who had post-surgical ctDNA detected were >85 times more likely to experience disease recurrence.
48% of post-NAT ctDNA detections were <100 PPM, highlighting the importance of NeXT Personal’s ultrasensitive performance.
Overall, the results suggest that ultrasensitive ctDNA detection in patients with TNBC after completion of NAT and prior to surgery may be used as a prognostic marker, independent of pCR, to guide clinical decision making for additional adjuvant therapies.
Dr. Luc Cabel, MD, PhD, Institut Curie, Paris, presented results from a second study titled "Ultrasensitive circulating tumor DNA (ctDNA) detection for prognostication in triple-negative breast cancer (TNBC) post-neoadjuvant chemotherapy (NAC)." This study included 86 patients with early stage (Stage I-III) TNBC receiving neoadjuvant therapy. Key findings included:

ctDNA was detected in 100% (84/84) of pretreatment baseline plasma samples.
The majority of ctDNA detections during NAT (51%) and post-NAT (55%) were in the ultrasensitive range below 100 PPM of ctDNA.
Post-NAT ctDNA status was highly prognostic. Patients with ctDNA detected post-NAT were ~36 times more likely to have a distant relapse than patients who tested negative.
For patients who were non-pCR, ctDNA negative patients were 93% less likely to relapse than ctDNA positive patients.
ctDNA status can be combined with pCR status to assess patient distant relapse risk following NAT.
Said François-Clément Bidard, MD, PhD, one of the Institut Curie lead investigators on the study, "Our results uncover the clinical need for ultrasensitive MRD testing, and pave the way for ctDNA-based adjuvant therapy decisions in early triple negative breast cancer."

As indicated by the data generated by Enterome’s ongoing SIDNEY study, EO2463 has the potential to become a frontline therapy in iNHL, either as monotherapy or in combination regimens, across all patient groups suffering from the disease, including in watch-and-wait settings, first-line therapy, and in relapsed/refractory settings.

The title of the peer-reviewed presentation is "EO2463 (EO) peptide immunotherapy in combination with lenalidomide (L) and rituximab (R) in patients (pts) with follicular (FL) and marginal zone lymphoma (MZL)", and will be presented by Dr Jose Caetano (JC) Villasboas Bisneto, principal study investigator at the Mayo Clinic in Rochester, MN, USA.

"We look forward to sharing these interim Phase 2 data, which suggest to us that our lead OncoMimics immunotherapeutic candidate EO2463 could have broad potential to benefit patients suffering from multiple clinical presentations of Follicular Lymphoma. Later this month, Dr Villasboas will present interim data obtained more specifically in iNHL patients with relapsed/refractory disease," said Pierre Bélichard, Chief Executive Officer of Enterome.

"Just this past weekend we presented positive Phase 1/2 data from the AUDREY trial in metastatic colorectal cancer with our second-most advanced OncoMimics immunotherapeutic candidate, EO4010, at ASCO (Free ASCO Whitepaper). OncoMimics represent a new therapeutic modality that has tremendous potential for cancer treatment."

Separately, Enterome recently held a positive Type-C meeting with the FDA, outlining a clear regulatory path to marketing approval for EO2463 in iNHL after constructive discussion with the regulator.

In addition, this week, Enterome will participate at the Jefferies Global Healthcare Conference in New York ( June 3 to 5). Pierre Bélichard and Chief Financial Officer Christelle Dumoussaud will meet with investors and industry partners during the event.

SIDNEY is a 12-month open label study that aims to assess safety, tolerability, immunogenicity, and preliminary efficacy of EO2463 monotherapy and combination therapy in some 48 patients with follicular lymphoma and marginal zone lymphoma. The study is comprised of four cohorts: 1) relapsed/refractory iNHL patients, who received EO2463 monotherapy for 6 weeks, followed by combination with lenalidomide plus rituximab for 16 weeks; 2) EO2463 monotherapy in newly diagnosed untreated stage III/IV iNHL classified as "watch and wait"; 3) EO2463 monotherapy followed by combination with rituximab in newly diagnosed previously untreated stage III/IV iNHL patients classified with low tumor burden in need of therapy; 4) relapsed/refractory iNHL patients, having received at least one prior treatment. EO2463 and lenalidomide are given in combination from treatment inception with addition of rituximab at week 19.

Enterome has previously presented interim data from the study at major international conferences held by the European Hematology Association (EHA) (Free EHA Whitepaper), the American Society of Hematology (ASH) (Free ASH Whitepaper), and the American Society for Cancer and Oncology.

EO2463 is an innovative, off-the-shelf immunotherapy candidate that combines four synthetic OncoMimic peptides. These non-self, microbial-derived peptides correspond to CD8 HLA-A2 epitopes that exhibit molecular mimicry with the B lymphocyte-specific lineage markers CD20, CD22, CD37, and CD268 (BAFF receptor). EO2463 also includes the helper peptide (CD4+ epitope) universal cancer peptide 2 (UCP2).

The unique ability of EO2463 immunotherapy to selectively target multiple B cell markers enables the destruction of malignant B lymphocytes. By ensuring broad target coverage across malignant B cells, this novel approach aims to simultaneously improve safety and maximize efficacy, reducing the tumor cells’ capacity to develop immune-resistance mechanisms such as antigen escape.

With extended follow-up and more mature data on progression-free survival (PFS) and overall survival (OS), IBI343 has demonstrated promising therapeutic efficacy in patients with CLDN18.2-positive advanced pancreatic cancer. These encouraging results suggest the potential of IBI343 in this challenging-to-treat malignancy. Supported by these robust clinical findings, IBI343 has been granted Breakthrough Therapy Designation (BTD) by China’s National Medical Products Administration (NMPA). Concurrently, the Phase 1 clinical trial of IBI343 is also being conducted in the United States, where the drug candidate has received Fast Track Designation (FTD) from the U.S. Food and Drug Administration (FDA).

Pancreatic cancer is one of the most aggressive malignancies worldwide. Most patients are diagnosed in the middle and late stages and often develop resistance to standard chemotherapy, resulting in a 5-year survival rate of less than 10%1. According to the GLOBOCAN 2022 statistics2, there are approximately 510,000 new cases and 467,000 deaths globally from pancreatic cancer each year, with China accounting for 120,000 new cases and 110,000 deaths annually.

This Phase 1/1b study is a multi-regional, dose escalation and expansion clinical trial (NCT05458219). Preliminary data were presented at ASCO (Free ASCO Whitepaper) 2025 and ESMO (Free ESMO Whitepaper) Asia 2024 and the updated results from the study’s dose-expansion cohort were presented at the 2025 ASCO (Free ASCO Whitepaper) as follows:

As of March 14, 2025, a total of 83 patients with pancreatic cancer had received at least one dose of IBI343 with a median follow-up time of 11.1 months.
As the data cutoff date, in patients with CLDN18.2 1+2+3+≥60% expression treated at the 6mg/kg dose (N=44), the confirmed overall objective response rate (cORR) was 22.7% and the disease control rate (DCR) was 81.8%. The median progression-free survival (mPFS) was 5.4 months, and the median overall survival (mOS) was 9.1 months. Among them, 17 patients had received only one line of prior treatment, achieving a mPFS of 5.4 months and a mOS of 12.1 months; and 18 patients had received two lines of prior treatment, the mPFS was 5.3 months and the mOS was 9.1 months.
The updated safety results demonstrated the favorable safety profile of IBI343 with a consistently low rate of gastrointestinal toxicity and no new safety signals. 98.8% of the patients experienced treatment-emergent adverse events (TEAEs), with the most common TEAEs being anemia, neutrophil count decreased, and white blood cell count decreased. Notably, no ≥ grade 3 nausea and vomiting occurred.
Professor Xianjun Yu from Fudan University Cancer Hospital, said, "Pancreatic cancer is one of the most malignant tumors of the digestive tract. Most patients are already in the advanced stage when diagnosed, and the 5-year survival rate is only about 10%1. Currently, chemotherapy is still the main first- and second-line treatment for advanced pancreatic cancer. The clinical options for second-line treatment are particularly limited, with a chemotherapy response rate of only 6-16%, median progression free survival of 2 to 5 months, and a median survival of approximately 6 to 9 months3, representing an urgent clinical need. With longer follow-up, the mature PFS and OS data from the latest IBI343 update demonstrate promising therapeutic potential, suggesting a breakthrough in this difficult-to-treat malignancy."

Dr. Hui Zhou, Senior Vice President of Innovent, said, "We are pleased to present an oral update on IBI343’s clinical data at this year’s ASCO (Free ASCO Whitepaper) conference. With the unique Fc-silent antibody design, stable linker and potent TOPO1i payload, IBI343 is the first ADC candidate to show encouraging efficacy and a favorable safety profile in the treatment of advanced pancreatic cancer. We hope to continue advancing the clinical trials of IBI343 for pancreatic cancer patients. Innovent will leverage its unique strengths in R&D innovation and clinical translation to develop a new generation of globally competitive oncology – focused innovative pipeline to benefit patients worldwide.."

About IBI343(Anti-CLDN18.2 ADC)

IBI343 is a recombinant human anti-CLDN18.2 monoclonal antibody-drug conjugate (ADC) developed by Innovent Biologics. IBI343 binds to the CLDN18.2-expressing tumor cells, the CLDN18.2 dependent ADC internalization will occur and the drug is released resulting in DNA damage and eventually apoptosis of the tumor cells. The freed drug can also diffuse across the plasma membrane to reach and kill the neighboring cells, resulting in "bystander killing effect".

As an innovative TOPO1i ADC, IBI343 has demonstrated tolerable safety and encouraging efficacy signals in Phase 1 clinical studies. The therapeutic potential of IBI343 is currently being explored in tumor types such as gastric and pancreatic cancer.

The Phase 3 trial of IBI343 for advanced gastric / gastroesophageal junction adenocarcinoma is now recruiting patients. The relevant indication has been included in China’s NMPA breakthrough therapy list.

IBI343’s Phase 1 trial for advanced pancreatic ductal adenocarcinoma is enrolling patients in an multi-regional study. This indication has received Fast Track designation from the FDA and been included in the NMPA’s BTD list.
