SHANGHAI and NANJING, China and SAN JOSE, CA, USA I July 2, 2023 I IASO Biotechnology ("IASO Bio"), a biopharmaceutical company engaged in discovering, developing, manufacturing and marketing innovative cell therapies and antibody products, and Innovent Biologics, Inc. ("Innovent", HKEX: 01801), a world-class biopharmaceutical company that develops, manufactures and commercializes high-quality medicines for the treatment of cancer, metabolic, autoimmune, ophthalmology and other major diseases, today announced that China National Medical Products Administration (NMPA) has approved the New Drug Application (NDA) for FUCASO (Equecabtagene Autoleucel, co-developed and co-commercialized by IASO Bio and Innovent, IASO Bio R&D code: CT103A, Innovent R&D code: IBI326), the world's first fully-human anti-B cell maturation antigen (BCMA) chimeric antigen receptor (CAR) T-cell therapy for the treatment of relapsed and/or refractory multiple myeloma (R/R MM) who received ≥3 lines of prior therapies containing at least one proteasome inhibitor and an immunomodulatory agent.
FUCASO® (Equecabtagene Autoleucel) is an autologous BCMA CAR-T cell injection, transduced by a lentiviral vector containing a CAR structure with a fully human scFv, CD8a hinger and transmembrane, 4-1BB co-stimulatory and CD3ζ activation domains. FUCASO® was given as a one-time treatment with a recommended dose of 1.0×106 CAR-T cells/kg. Based on strict selection and screening of the molecular structures, using a proprietary in-house optimization platform and integrated in-house manufacturing process, FUCASO® is potent and shows prolonged persistency in patients. It will bring new treatment options to R/R MM patients with higher and more profound responses.
The NDA approval is based on the data from the pivotal FUMANBA-1 study (CTR20192510, NCT05066646) conducted at multiple sites in China. In June 2023, the updated data from FUMANBA-1 study was presented at the 2023 Annual Meeting of the American Society of Clinical Oncology (ASCO) (Abstract Number: 8025). The study enrolled 103 R/R MM patients with a median follow-up time of 13.8 (0.4, 27.2) months.
- Among the 101 evaluable patients, the overall response rate (ORR) was 96%, with the stringent complete response/ complete response (sCR/CR) rate of 74.3%. Median time to response (mTTR) was only 16 days, and the 12-month Progression-Free Survival (PFS) rate was 78.8%. 95% of the patients achieved minimal residual disease (MRD) negativity, and all sCR/CR patients achieved MRD negativity. Of the 12 patients with prior CAR-T therapy, 9 achieved response, and 5 achieved sCR (including 4 patients achieved sustained sCR for over 18 months post-infusion). In 89 patients without prior CAR-T therapy, 78.7% reached sCR/CR.
- Of the 103 safety evaluable patients, only one experienced grade ≥3 cytokine release syndrome (CRS), and 2 experienced grade 1-2 immune effector cell-associated neurotoxicity syndrome (ICANS). All patients with CRS or ICANS recovered after the treatment.
- FUCASO® was still detectable in 50% and 40% respectively of the patients who completed 12-month and 24-month follow-ups after infusion. Only 19.4% of the patients were anti-drug antibody (ADA)-positive.
"There's a significant unmet medical need for the treatment of multiple myeloma in China. As a fully-human BCMA CAR-T therapy, FUCASO® has demonstrated remarkable efficacy, with evidence of deep and durable response. Its approval also offers clinicians more options to treat R/R MM patients after multi-lines of treatment," said Prof. Lugui Qiu, MD, Chinese Academy of Medical Science Hematology Hospital, and Prof. Chunrui Li, MD, PhD, Tongji Hospital, Tongji Medical College, Huazhong University of Science & Technology, who is the principal investigators of the registration trial of FUCASO®.
Ms. Jinghua Zhang, Chairman and Chief Executive Officer of IASO Bio, stated, "We are excited that FUCASO® was approved, it is a significant milestone for the Company. FUCASO® is not only IASO Bio's first marketed product but is also the world's first commercially available fully-human CAR-T therapy. Furthermore, FUCASO® is the first self-developed and in-house manufactured CAR-T cell therapy in China as well as China's first approved BCMA CAR-T for the treatment of multiple myeloma. The NMPA NDA approval of FUCASO® will help us in achieving our strategic goal of bringing break through therapy to patients in unmet need, with the hope for a potential cure."
Dr. Hui Zhou, Senior Vice President of Innovent Biologics, stated, "Multiple myeloma is a common hematology malignant disease with high incidence rate, and relapse and refractory are inevitable after current treatments. There's an urgent unmet need requesting a treatment with well-tolerated and long persistence for patients. FUCASO®, as an innovative fully-human cell therapy, has demonstrated robust and long-lasting efficacy and outstanding safety in long-term follow-up data from the registrational clinical study, which underscores its potential to be a pioneering treatment option for patients with RRMM. We are very pleased with the successful approval of FUCASO® and hope it could benefit RRMM patients as the first approved BCMA CAR-T therapy in China.."
About Multiple Myeloma (MM)
Multiple Myeloma (MM) is a deadly blood cancer that often infiltrates the bone marrow causing anemia, kidney failure, immune problems, and bone fractures. For MM patients, common first-line drug treatments include proteasome inhibitors, immunomodulatory drugs, and alkylating agents. While treatment may result in remission, most patients will inevitably enter the relapsed or refractory stage as there's currently no cure. As a result, there is a significant unmet need for patients with relapsed/refractory multiple myeloma. According to Frost & Sullivan, new MM cases in China rose from 20,100 in 2018 to 22,400 in 2022 and are expected to increase to 25,700 by 2027.
