SHANGHAI<\/span><\/span>, June 15, 2024<\/span><\/span> \/PRNewswire\/ — CARsgen Therapeutics Holdings Limited (Stock Code: 2171.HK), a company focused on innovative CAR T-cell therapies for the treatment of hematologic malignancies and solid tumors, announces that the initial results from the ongoing first-in-human study of CT071 have been presented at the 29th Annual Congress of the European Hematology Association (EHA).<\/p>\n

\n<\/p><\/div>\n

The preliminary results of Phase I of CT071 (NCT05838131) were presented as a poster at the 29th EHA Annual Congress on June 14<\/span>, 18:00 – 19:00 CEST<\/span>, which was titled "First-in-human study of GPRC5D-targeted CAR T cells (CT071) with an accelerated manufacturing process in patients with relapsed\/ refractory multiple myeloma (RRMM)".[1]<\/sup><\/p>\n

"Multiple myeloma is a common yet incurable hematologic malignancy with high unmet need. Despite the numerous recent advances, most patients relapse and become refractory to available therapies and therefore, novel therapies are needed. GPRC5D, a protein highly expressed on the surface of malignant plasma cells with limited expression on normal tissues, represents a promising target for treating multiple myeloma. CT071 is a fully human GPRC5D-targeting autologous second-generation CAR T-cell product manufactured using our expedited CARcelerateTM <\/sup>platform that shortens the manufacturing time to around 30 hours, supporting a shorter vein-to-vein time and younger T cells. The preliminary results of the ongoing study presented at EHA shows that CT071 has the potential to be the best-in-class GPRC5D targeting CAR-T therapy," said Raffaele Baffa<\/span>, M.D., Ph.D., Chief Medical Officer of CARsgen Therapeutics. "We are excited about advancing CT071 and look forward to sharing future updates with the medical community."<\/p>\n

As of February 28, 2024<\/span>, 10 patients were dosed with CT071\u20147 patients at 1.0×105<\/sup> cells\/kg and 3 patients at 3.0×105<\/sup> cells\/kg. Among them, 80% had high-risk cytogenetics, 30% had one or more extramedullary plasmacytomas (EMD), and 40% were at R-ISS stage III. This was a heavily pre-treated population with a median of 5 prior lines of therapy, including 90% double-class refractory, 70% triple-class refractory, 40% penta-drug refractory, 50% having received autologous stem cell transplantation, and 20% had previously been treated with BCMA\/CD19 dual-targeting CAR T cells. None of the patients on the study required bridging therapy due to rapid manufacturing turnaround.<\/p>\n

The median follow-up at the time of data cut-off was 4.07 months (range: 2.8-7.4). There were no Grade 3 or higher cytokine release syndrome (CRS) events. No immune effector cell-associated neurotoxicity syndrome (ICANS) was observed. No adverse events of special interest or dose limiting toxicity (DLT) occurred. Four patients experienced treatment-related SAE, including pneumonia (n=1), decreased appetite (n=1) and thrombocytopenia (n=2), and all recovered.<\/p>\n

The overall response rate was 90%, including 5 patients (50%) with stringent complete response (sCR), 2 patients (20%) with very good partial response (VGPR), and 2 patients (20%) with partial response (PR). All the 9 patients with evaluable MRD assessment at Week 4 achieved MRD negativity (10-6<\/sup> threshold) ), including all 5 patients with sCR\/CR.<\/span> The pharmacokinetic analysis demonstrated robust cell expansion and persistence, with median Tmax<\/sub> of 14 days (range: 12-28) and median Cmax<\/sub> of 32280.5 copies\/\u03bcg gDNA (range: 8372-106060).<\/p>\n

About CT071
<\/b>CT071 is a CAR T-cell therapy candidate developed utilizing CARsgen’s proprietary CARcelerateTM<\/sup> platform targeting GPRC5D for the treatment of R\/R MM or relapsed\/refractory plasma cell leukemia ("R\/R PCL"). An investigator-initiated trial (NCT05838131) is ongoing in China<\/span> to evaluate the safety and efficacy of CT071 for the treatment of R\/R MM or R\/R PCL. Another investigator-initiated trial (NCT06407947) is ongoing in China<\/span> for the treatment of newly diagnosed multiple myeloma (NDMM).<\/p>\n
