Announce U.S. FDA IND Clearance for Lead Multispecific Antibody Cancer Candidate ABP-102 / CT-P72Abpro Holdings, Inc. announced, together with its co-development partner Celltrion, Inc., that the U.S. Food and Drug Administration (FDA) has cleared the Investigational New Drug (IND) application for ABP-102 /CT-P72, Abpro's lead multispecific antibody oncology program. The IND clearance enables the initiation of a Phase 1 clinical trial evaluating the safety, tolerability, pharmacokinetics, and preliminary efficacy of ABP-102 /CT-P72 in patients with HER2-positive solid tumors. The Phase 1 clinical study will be led by Celltrion as part of the ongoing joint strategic collaboration to ensure the robust progression of the ABP-102 /CT -P72 program. ABP-102 /CT the company is a multispecific HER2 x CD3 T-cell engager engineered to selectively target HER2-overexpressing tumor cells while engaging cytotoxic T cells, with optimized binding designed to enhance tumor selectivity and limit activity in normal HER2-low tissues. This design is intended to direct immune activity toward cancer cells while seeking to minimize damage to healthy tissue, addressing a key safety challenge that has limited the use of T-cell engagers in solid tumors. In preclinical studies, ABP-102 /CT/CT-P72 demonstrated robust antitumor activity in HER2-high tumor models, including dual xenograft models containing both HER2-high and HER2-low tumors, with selective efficacy for HER2-high tumors. The optimized CD3 binding of ABP-102/CT-P72, functionally linked with HER2-high selectivity, is intended to mitigate excessive immune activation and reduce the risk of cytokine release syndrome. Non-human primate toxicology studies showed the candidate was well tolerated at doses up to 80 mg/kg, with no significant adverse effects observed, supporting a differentiated therapeutic index. Additional preclinical evaluations demonstrated activity in tumor models representing resistance to existing HER2-directed therapies, highlighting the potential to address areas of unmet medical need. Preclinical data sets for ABP-102 /TC-P72 have been presented at major scientific meetings, including the 2025 Annual Meeting of the American Association for Cancer Research and the 2025 Annual Meeting of the Society for Immunotherapy of Cancer. Following IND clearance, Abpro and Celltrion plan to initiate a global Phase 1 clinical trial in the first half of 2026, subject to final site activation and regulatory processes. The study is expected to include dose-escalation and dose-expansion cohorts and will inform future clinical development strategies.最新情報をもっと見るRecent updatesお知らせ • May 16Abpro Holdings, Inc. announced delayed 10-Q filingOn 05/15/2026, Abpro Holdings, Inc. announced that they will be unable to file their next 10-Q by the deadline required by the SEC.お知らせ • Apr 01Abpro Holdings, Inc. announced delayed annual 10-K filingOn 03/31/2026, Abpro Holdings, Inc. announced that they will be unable to file their next 10-K by the deadline required by the SEC.お知らせ • Feb 21Abpro Holdings, Inc.

ABP-102/CT-P72, a tetravalent bispecific HER2 x CD3 T-cell engager co-developed with Celltrion, is engineered to selectively target HER2-overexpressing tumors while reducing the risk of on-target, off-tumor toxicity in normal tissues. Preclinical findings presented at AACR suggest the potential of ABP-102/CT-P72 to surpass existing HER2-targeted therapies in both efficacy and safety. Key Findings: Highly Selective Tumor Killing: ABP-102/CT-P72 achieves potent cytotoxicity in HER2-overexpressing breast and gastric cancer models while significantly reducing activity against HER2-low cells, addressing a key limitation of prior HER2-targeted T-cell engagers. Enhanced Tumor Growth Inhibition: In vivo studies showed ABP-102/CT-P72 had up to a two-fold increase in tumor suppression compared to a biosimilar of runimotamab, a benchmark HER2 x CD3 bispecific antibody. Reduced Cytokine Release: Engineered for functionally monovalent CD3 binding, ABP-102/CT-P72 minimizes cytokine-related toxicities, as demonstrated by reduced cytokine release in HER2-low cell models while maintaining potent cytotoxicity in HER2-high models. Improved Tolerability: Dose escalation studies in cynomolgus monkeys confirmed that ABP-102/CT-P72 was well tolerated, even at doses exceeding 180 times the maximum tolerated dose observed with the parental antibody, suggesting a broader therapeutic window. The combination of HER2-selective T-cell activation, reduced cytokine release in HER2-low environments, and high tolerability in non-human primates underscores how ABP-102/CT-P72’s functionally monovalent CD3 binding strategy successfully mitigates on-target off-tumor toxicity. These attributes position ABP-102/CT-P72 as a potentially safer alternative to previous HER2-targeting T-cell engagers, paving the way for a broader therapeutic window in clinical trials, which are planned to start in the first half of 2026.お知らせ • Apr 09Abpro Holdings Receives Written Notice from the Listing Qualifications Department of the Nasdaq Stock MarketOn April 2, 2025, Abpro Holdings, Inc. received written notice from the Listing Qualifications Department of The Nasdaq Stock Market notifying the Company that, based on the closing bid price of the Company’s common stock for the last 30 consecutive business days, the Company no longer complies with the minimum bid price requirement for continued listing on The Nasdaq Stock Market LLC.

お知らせ • Jan 07Abpro Holdings, Inc. and Celltrion, Inc. Announce U.S. FDA IND Clearance for Lead Multispecific Antibody Cancer Candidate ABP-102 / CT-P72Abpro Holdings, Inc. announced, together with its co-development partner Celltrion, Inc., that the U.S. Food and Drug Administration (FDA) has cleared the Investigational New Drug (IND) application for ABP-102 /CT-P72, Abpro's lead multispecific antibody oncology program. The IND clearance enables the initiation of a Phase 1 clinical trial evaluating the safety, tolerability, pharmacokinetics, and preliminary efficacy of ABP-102 /CT-P72 in patients with HER2-positive solid tumors. The Phase 1 clinical study will be led by Celltrion as part of the ongoing joint strategic collaboration to ensure the robust progression of the ABP-102 /CT -P72 program. ABP-102 /CT the company is a multispecific HER2 x CD3 T-cell engager engineered to selectively target HER2-overexpressing tumor cells while engaging cytotoxic T cells, with optimized binding designed to enhance tumor selectivity and limit activity in normal HER2-low tissues. This design is intended to direct immune activity toward cancer cells while seeking to minimize damage to healthy tissue, addressing a key safety challenge that has limited the use of T-cell engagers in solid tumors. In preclinical studies, ABP-102 /CT/CT-P72 demonstrated robust antitumor activity in HER2-high tumor models, including dual xenograft models containing both HER2-high and HER2-low tumors, with selective efficacy for HER2-high tumors. The optimized CD3 binding of ABP-102/CT-P72, functionally linked with HER2-high selectivity, is intended to mitigate excessive immune activation and reduce the risk of cytokine release syndrome. Non-human primate toxicology studies showed the candidate was well tolerated at doses up to 80 mg/kg, with no significant adverse effects observed, supporting a differentiated therapeutic index. Additional preclinical evaluations demonstrated activity in tumor models representing resistance to existing HER2-directed therapies, highlighting the potential to address areas of unmet medical need. Preclinical data sets for ABP-102 /TC-P72 have been presented at major scientific meetings, including the 2025 Annual Meeting of the American Association for Cancer Research and the 2025 Annual Meeting of the Society for Immunotherapy of Cancer. Following IND clearance, Abpro and Celltrion plan to initiate a global Phase 1 clinical trial in the first half of 2026, subject to final site activation and regulatory processes. The study is expected to include dose-escalation and dose-expansion cohorts and will inform future clinical development strategies.

お知らせ • Apr 28Abpro and Celltrion Unveil Preclinical Data for ABP-102/CT-P72 at AACR 2025, Showcasing Potential Best-in-Class HER2 x CD3 T-Cell EngagerAbpro Holdings, Inc. and Celltrion unveiled preclinical data for ABP-102/CT-P72 in an oral presentation at the American Association for Cancer Research® (AACR) Annual Meeting 2025, in the New Drugs on the Horizon session. ABP-102/CT-P72, a tetravalent bispecific HER2 x CD3 T-cell engager co-developed with Celltrion, is engineered to selectively target HER2-overexpressing tumors while reducing the risk of on-target, off-tumor toxicity in normal tissues. Preclinical findings presented at AACR suggest the potential of ABP-102/CT-P72 to surpass existing HER2-targeted therapies in both efficacy and safety. Key Findings: Highly Selective Tumor Killing: ABP-102/CT-P72 achieves potent cytotoxicity in HER2-overexpressing breast and gastric cancer models while significantly reducing activity against HER2-low cells, addressing a key limitation of prior HER2-targeted T-cell engagers. Enhanced Tumor Growth Inhibition: In vivo studies showed ABP-102/CT-P72 had up to a two-fold increase in tumor suppression compared to a biosimilar of runimotamab, a benchmark HER2 x CD3 bispecific antibody. Reduced Cytokine Release: Engineered for functionally monovalent CD3 binding, ABP-102/CT-P72 minimizes cytokine-related toxicities, as demonstrated by reduced cytokine release in HER2-low cell models while maintaining potent cytotoxicity in HER2-high models. Improved Tolerability: Dose escalation studies in cynomolgus monkeys confirmed that ABP-102/CT-P72 was well tolerated, even at doses exceeding 180 times the maximum tolerated dose observed with the parental antibody, suggesting a broader therapeutic window. The combination of HER2-selective T-cell activation, reduced cytokine release in HER2-low environments, and high tolerability in non-human primates underscores how ABP-102/CT-P72’s functionally monovalent CD3 binding strategy successfully mitigates on-target off-tumor toxicity. These attributes position ABP-102/CT-P72 as a potentially safer alternative to previous HER2-targeting T-cell engagers, paving the way for a broader therapeutic window in clinical trials, which are planned to start in the first half of 2026.
