Tislelizumab

SAN FRANCISCO and SUZHOU, China, June 3, 2025 /PRNewswire/ -- Innovent Biologics, Inc. ("Innovent") (HKEX: 01801), a world-class biopharmaceutical company that develops, manufactures and commercializes high-quality medicines for the treatment of oncology, autoimmune, cardiovascular and metabolic, ophthalmology and other major diseases, announced the third oral presentation of clinical data for IBI363 (first-in-class PD-1/IL-2α-bias bispecific antibody fusion protein) in advanced non-small cell lung cancer at the 2025 American Society of Clinical Oncology (ASCO), following IBI363's other two oral presentations in colorectal cancer and melanoma. A manageable safety profile, encouraging efficacy, and trends in long-term survival benefits have been observed in both immunotherapy-resistant squamous non-small cell lung cancer (NSCLC) and wild-type lung adenocarcinoma. It is worth mentioning that Innovent's pipeline has a total of 8 oral presentations at this ASCO conference, representing approximately 2% of the conference's total oral presentations. Innovent Biologics is conducting clinical studies in China, the United States, and Australia to explore the efficacy and safety of IBI363 for multiple tumor indications, including immune resistance, cold tumors, and front-line treatments. At this year's ASCO meeting, three oral presentations of IBI363 reported encouraging Phase 1/2 clinical data in the first three indications explored—NSCLC, CRC, and melanoma—focusing on IO-resistant and cold tumors. The data comprehensively demonstrated the breakthrough clinical outcomes of IBI363 across these indications, from robust tumor response to long-term survival benefits. These findings provide strong support of the drug's novel mechanism of action translating effectively into clinical outcomes, and imply its potential for broader clinical development, offering new hope in areas of immunotherapy where treatment options remain limited. PD-1/IL-2α-bias bispecific antibody fusion protein IBI363 in patients with immunotherapy resistant advanced non-small cell lung cancer: results from a Phase 1 study Updated data on IBI363 monotherapy in patients with advanced NSCLC were reported (ClinicalTrials.gov, NCT05460767). As of the data cutoff date, April 7, 2025, a total of 136 patients with NSCLC had received IBI363 monotherapy (2 μg/kg QW~4mg/kg Q3W), including 67 with squamous cell carcinoma and 58 with EGFR wild-type adenocarcinoma. IBI363 showed breakthrough therapeutic potential from tumor response to long-term survival benefit in immuno-resistant squamous NSCLC All 67 squamous NSCLC patients were EGFR wild type. Among them, 28 patients received IBI363 at 1 mg/kg Q2W or 1.5 mg/kg Q3W, and 31 patients received IBI363 at 3 mg/kg Q3W. In the two groups of patients, the proportion of ≥2 lines of previous systemic therapy was 64.3% (18/28) vs 67.7% (21/31), the proportion of previous anti-PD-1/PD-L1 therapy was 100% (28/28) vs 96.8% (30/31) and the proportion of PD-L1 TPS<1% was 35.7% (10/28) vs 41.9% (13/31). In the 1/1.5 mg/kg dose group, promising ORR/DCR/PFS/OS were observed. Median OS achieved 15.3 months, suggesting the potential long-term survival benefit of IBI363 as a PD-1/IL-2α-bias bispecific immunotherapy. Compared with the 1/1.5 mg/kg dose group, the 3 mg/kg Q3W dose group observed more prominent confirmed ORR (36.7%), DCR (90.0%), PFS (median PFS 9.3 months) and OS trends (median OS not reached, 12-month OS rate 70.9%) (see the table below). Among the patients with PD-L1 TPS<1%, IBI363 demonstrated outstanding efficacy signals: in the 1/1.5 mg/kg group (N=10), the confirmed ORR was 30.0% and the DCR was 90.0%, while that of the 3 mg/kg group (N=13) were 46.2% and 92.3%, suggesting the potential advantage of IBI363 in the population with low expression of PD-L1. IBI363 showed potential for long-term survival benefits in immuno-resistant wild-type lung adenocarcinoma, especially in patients with smoking history Among the 58 patients with EGFR wild-type lung adenocarcinoma, 30 patients received IBI363 at 0.6 mg/kg Q2W or 1 mg/kg Q2W or 1.5 mg/kg Q3W, 25 patients received IBI363 at 3 mg/kg Q3W. In the two groups of patients, the proportions of ≥2 lines of previous systemic therapy were 80.0% (24/30) vs 64.0% (16/25), the proportions of previous anti-PD-1/PD-L1 therapy were both 100%, the proportions of PD-L1 TPS<1% were 26.7% (8/30) vs 40.0% (10/25) and the proportions of smoking history were 56.7% (17/30) vs 60.0% (15/25). In the 1/1.5 mg/kg dose group, median OS achieved 17.5 months, suggesting the potential long-term survival benefit of IBI363 as a PD-1/IL-2α-bias bispecific immunotherapy. Compared with the 0.6/1/1.5 mg/kg dose group, the 3 mg/kg dose group observed higher confirmed ORR (24.0%), DCR (76.0%), PFS (median PFS 5.6 months) and OS trends (median OS not reached, 12-month OS rate 71.6%) (see the table below). Higher ORR and PFS were observed in lung adenocarcinoma patients with a history of smoking. Among them, the confirmed ORR in the 0.6/1/1.5 mg/kg group (N=17) was 23.5%, and the confirmed ORR in the 3 mg/kg group (N=15) was 33.3%. In all dose groups (N=32), the median PFS of smokers was longer than non-smokers: 5.3 (2.0, 7.0) vs 3.0 (1.6, 5.1) months. In terms of long-term survival benefits, after follow-ups of 12.0 and 13.7 months, the median OS for non-smokers was 13.6 months, whereas the median OS for smokers was not yet reached, with only 9 (28.1%) events occurring. IBI363 had a manageable safety profile in advanced NSCLC Among the 57 patients with NSCLC in the 3 mg/kg dose group, the most common treatment related adverse events (TRAEs) of grade 3 or above were arthralgia and rash. 7.0% of patients experienced TRAEs leading to discontinuation. The overall safety profile was manageable. In view of the encouraging efficacy signals and manageable safety demonstrated by IBI363 monotherapy, Innovent plans to conduct a Phase 3 registration clinical study in locally advanced or metastatic squamous NSCLC that has failed platinum-based chemotherapy and anti-PD-1 /PD-L1 immunotherapy. As of now, IBI363 has received Breakthrough Therapy (BTD) certification from China CDE and Fast Track Designation (FTD) from the US FDA for squamous NSCLC. Professor Jianya Zhou, The First Affiliated Hospital, School of Medicine, Zhejiang University, stated: "Lung cancer is the malignant tumor with the highest incidence and mortality rate both globally and in China[1], and it is a major issue endangering public health. Although immunotherapy has completely transformed the treatment landscape of NSCLC, for patients with wild-type NSCLC who have failed immunotherapy, the current standard treatment regimen docetaxel has limited efficacy, with an ORR of less than 20%, a PFS of less than 4 months, and an OS of less than 12 months [2-7]. In recent years, although the exploration of new treatment regimens such as immune combination therapy and antibody drug conjugates (ADCs) has brought new hope, many large-scale Phase 3 clinical studies on NSCLC patients who have failed platinum-based chemotherapy and immunotherapy have not achieved satisfactory results, and most of these studies have not met the primary endpoints[2-6]. Although the TROPION-Lung01 study achieved the primary endpoint of PFS in NSCLC, it did not reach the primary endpoint of OS. Especially in squamous NSCLC, no improvement was observed in PFS/OS/ORR in the experimental group. Therefore, there was a huge and urgent unmet medical need in NSCLC that has failed immunotherapy. As a PD-1/IL-2α-bias bispecific molecule, IBI363 not only shows clinical benefits in both ORR and PFS in immune-resistant NSCLC, but also enables us to see the potential of the tailing effect of immunotherapy to bring long-term survival benefits to patients compared with chemotherapy. We are also more looking forward to the survival data of the long-term follow up in the high dose IBI363 group." Dr. Hui Zhou, Senior Vice President of Innovent, stated: "It is a great pleasure to orally present the latest progress of IBI363 in the field of lung cancer at the ASCO conference. IBI363 shows remarkable efficacy in immune-resistant wild-type nsclc and clinical data suggests better trends in ORR, DCR, PFS and OS at higher doses. We expect longer-term follow-up to bring more mature data and look forward to seeing its potential as an immunotherapy for the long-term survival benefits of patients. Meanwhile, regardless of the expression level of PD-L1, IBI363 has demonstrated a powerful anti-tumor effect in immune-resistant NSCLC (especially squamous NSCLC), suggesting that the effect of IBI363 does not depend on the expression of PD-L1. In the future, it may also bring breakthroughs in cold tumors with low or no expression of PD-L1. We will continue to advance the clinical exploration of IBI363 in NSCLC and other tumor types." About IBI363 (First-in-class PD-1/IL-2α-bias bispecific antibody fusion protein) IBI363 is a first-in-class PD-1/IL-2α-bias bispecific antibody fusion protein independently developed by Innovent Biologics. It functions by both blocking the PD-1/PD-L1 pathway and activating the IL-2 pathway. The IL-2 arm of IBI363 is designed to maintain its affinity for IL-2Rα while reducing binding to IL-2Rβ and IL-2Rγ, thereby minimizing toxicity. The PD-1 binding arm not only blocks PD-1 but also selectively delivers IL-2. This approach targets and activates tumor-specific T cells that express both PD-1 and IL-2α, leading to more precise and effective activation of this T cell subpopulation. IBI363 has demonstrated robust antitumor activity in various tumor-bearing pharmacological models, but also showed outstanding efficacy in PD-1 resistance and metastasis models. In response to urgent clinical needs, Innovent is conducting clinical studies in China, the United States and Australia to further explore the efficacy and safety of IBI363 in various tumor indications, including immune-resistant, cold tumors, and front-line treatments. The first pivotal trial of IBI363 was initiated in 2025 for unresectable locally advanced or metastatic mucosal or acral melanoma who have not received prior systemic therapy. IBI363 has received two fast track designations (FTD) from the U.S. FDA and two breakthrough designations (BTD) from the China NMPA, for the treatment of squamous non-small cell lung cancer and melanoma, respectively.

New trial arm to evaluate safety, dosing and preliminary anti-tumor activity of the combination therapy in advanced solid tumorsNEW YORK, June 02, 2025 (GLOBE NEWSWIRE) -- Indaptus Therapeutics, Inc. (Nasdaq: INDP), a clinical-stage biotechnology company dedicated to developing novel treatments for cancer and viral infections, announces that the first patient has been dosed in the expansion arm of its Phase 1b/2 clinical trial evaluating Decoy20 in combination with BeOne’s (formerly known as Beigene) PD-1 checkpoint inhibitor, tislelizumab. This newly activated arm of the trial will assess safety, dose optimization, and early signs of anti-tumor activity in patients with advanced solid tumors, previously treated with a checkpoint inhibitor or with tumors typically unresponsive to a checkpoint inhibitor. Jeffrey Meckler, Indaptus’ CEO commented, “This is an important milestone in our clinical development. We have long believed the Decoy platform has the potential to be a game-changing approach to treating solid tumors. Preclinical data consistently demonstrated that Decoy20 works synergistically with a checkpoint inhibitor. Now, for the first time, we are testing this combination in patients. Checkpoint inhibitors, like tislelizumab, have been one of the biggest breakthroughs in cancer therapy and have significantly improved outcomes in a variety of cancers. However, most patients still do not benefit. We believe the combination of Decoy20 plus a PD-1 inhibitor, such as tislelizumab, could enhance immune responses, potentially helping patients who have not responded or have tumors that classically do not respond to checkpoint inhibitor therapy.” About the Combination Trial Over 25 patients have now received weekly doses of Decoy20 at 30 million cells and the treatment has been well tolerated. Most side effects were mild or moderate and were transient.Patients enrolled in the Decoy20 + tislelizumab combination arm will either have tumors that did not respond – or stopped responding – to prior checkpoint inhibitor therapy, or have tumor types that are typically unresponsive. This will allow the Company to determine that any observed benefit is likely due to the combination approach. Initially, patients will be enrolled sequentially onto combination treatment to closely monitor safety before expanding enrollment. About PD-1 Inhibitors PD-1 inhibitors work by blocking the PD-1 (programmed death-1) receptor on T cells, preventing cancer cells from evading the immune system and restoring the body’s ability to fight cancer. Combining checkpoint inhibitors with immune system activators such as Decoy20 could provide a more powerful and sustained anti-tumor response. Indaptus is committed to advancing innovative therapies that harness the immune system to fight cancer. With the launch of this combination trial, the Company is taking a major step towards realizing the full potential of its Decoy platform. About Indaptus Therapeutics Indaptus Therapeutics has evolved from more than a century of immunotherapy advances. The Company’s novel approach is based on the hypothesis that efficient activation of both innate and adaptive immune cells and pathways and associated anti-tumor and anti-viral immune responses will require a multi-targeted package of immune system-activating signals that can be administered safely intravenously (i.v.). Indaptus’ patented technology is composed of single strains of attenuated and killed, non-pathogenic, Gram-negative bacteria producing a multiple Toll-like receptor (TLR), Nucleotide oligomerization domain (NOD)-like receptor (NLR) and Stimulator of interferon genes (STING) agonist Decoy platform. The product candidates are designed to have reduced i.v. toxicity, but largely uncompromised ability to prime or activate many of the cells and pathways of innate and adaptive immunity. Decoy product candidates represent an antigen-agnostic technology that have produced single-agent activity against metastatic pancreatic and orthotopic colorectal carcinomas, single agent eradication of established antigen-expressing breast carcinoma, as well as combination-mediated eradication of established hepatocellular carcinomas, pancreatic and non-Hodgkin’s lymphomas in standard pre-clinical models, including syngeneic mouse tumors and human tumor xenografts. In pre-clinical studies tumor eradication was observed with Decoy product candidates in combination with anti-PD-1 checkpoint therapy, low-dose chemotherapy, a non-steroidal anti-inflammatory drug, or an approved, targeted antibody. Combination-based tumor eradication in pre-clinical models produced innate and adaptive immunological memory, involved activation of both innate and adaptive immune cells, and was associated with induction of innate and adaptive immune pathways in tumors after only one i.v. dose of Decoy product, with associated “cold” to “hot” tumor inflammation signature transition. IND-enabling, nonclinical toxicology studies demonstrated i.v. administration without sustained induction of hallmark biomarkers of cytokine release syndromes, possibly due to passive targeting to liver, spleen, and tumor, followed by rapid elimination of the product. Indaptus’ Decoy product candidates have also produced significant single agent activity against chronic hepatitis B virus (HBV) and chronic human immunodeficiency virus (HIV) infections in pre-clinical models.
