Mont-Saint-Guibert, Belgium; February 18, 2025, 7:00 am CET – Celyad Oncology (Euronext: CYAD) (the “Company”), today announces the publication of the preclinical data of the non-gene edited allogeneic CYAD-211 and clinical data from the Phase I IMMUNICY-1 clinical study which evaluated CYAD-211 in relapsed or refractory (r/r) multiple myeloma (MM) patients. The findings were published in the International Journal of Molecular Science (IJMS). CYAD-211 is the Company’s first allogeneic chimeric antigen receptor (CAR) T-cell candidate, engineered to co-express a B-cell maturation antigen (BCMA)-specific CAR and a microRNA-based single shRNA which interferes with the expression of the CD3ζ component of the T-cell receptor (TCR) complex, evaluated clinically. The IJMS publication includes preclinical data which showcases the knockdown of CD3ζ efficiently removed the TCR complex from the cell surface, and inhibited TCR mediated activation in vitro and in vivo. The publication also presents clinical data of the dose-escalation segment of the IMMUNICY-1 phase-I clinical trial (NCT04613557) in patients with r/r MM. Importantly, data highlighted an overall good safety profile and some clinical responses, with no signs of graft-versus-host disease (GvHD), demonstrating the effectiveness and safeness of the technology to abrogate the risk of GvHD. Overall, these data provides the proof-of-concept of the safe administration of CAR T-cells engineered using a miRNA-based shRNA technology. CYAD-211 is the first allogeneic CAR T-cell candidate using a non-gene edited approach to achieve allogenicity. This differentiated strategy provides key advantages by being easily implemented, safe, efficient, tunable, and with the possibility to modulate multiple target genes simultaneously.

SHANGHAI and NANJING, China and SAN JOSE, Calif., Feb. 14, 2025 /PRNewswire/ -- IASO Biotherapeutics ("IASO Bio"), a biopharmaceutical company focused on the discovery, development, manufacturing, and commercialization of innovative cell therapies and biologics, today announced that the Hong Kong Department of Health (DOH) has officially accepted the New Drug Application (NDA) for Equecabtagene Autoleucel. This treatment is indicated for patients with relapsed and/or refractory multiple myeloma (R/R MM) who have received three or more prior lines of therapies. Equecabtagene Autoleucel (trade name: FUCASO) was approved by China's National Medical Products Administration (NMPA) on June 30, 2023, for treating adult patients with relapsed or refractory multiple myeloma (R/RMM) who have received three or more lines of prior therapies, including at least one proteasome inhibitor and an immunomodulatory agent. As the world's first commercialized fully human CAR-T product, FUCASO has gained recognition from healthcare professionals and patients in China for its remarkable efficacy and safety since its launch. Furthermore, it has also attracted patients from over ten regions/countries to China to receive this innovative therapy. Ms. Jinhua Zhang, Founder, Chairwoman, and CEO of IASO Bio, stated: "We are delighted that the New Drug Application for Equecabtagene Autoleucel has been officially accepted by the Hong Kong Department of Health. Hong Kong occupies a 'frontline position' for biopharmaceutical companies in mainland China to expand into global markets, making it a key step in IASO Bio's journey to 'go global.' Thanks to the latest '1+' Mechanism introduced by the Hong Kong Department of Health, we swiftly submitted the NDA. This not only demonstrated our regulatory team's in-depth understanding of and swift response to drug regulatory policies in different regions and countries, but also marks our first successful practice in adopting a flexible and localized registration strategy. We will actively collaborate with the DOH throughout the regulatory process and strive to expedite the launch of this CAR-T therapy in Hong Kong. Fully believing in the outstanding clinical value of Equecabtagene Autoleucel, we have also submitted NDAs in other regions and countries. We remain committed to accelerating access to advanced CAR-T therapies for patients around the world." About Multiple Myeloma （ MM) Multiple myeloma (MM) is the second most common hematological malignancy globally. According to Globocan data, the global incidence of multiple myeloma in 2022 was 1.8 per 100,000 people, with a 5-year prevalence of 6.8 per 100,000. Despite progress in current anti-myeloma treatments, MM remains largely incurable with multiple relapses and tendency to develop refractoriness to several drug classes, presenting a major therapeutic challenge. Thus, there is an unmet need for new treatment options beyond these current anti-myeloma therapies for the treatment of relapsed or refractory MM, capable of achieving deep and durable responses.
