The abstract selected for online publication was submitted on February 14, 2023. On May 25, 2023, Theseus plans to host a virtual investor event to present data with an updated cutoff date. The data to be presented from the ongoing dose escalation study are expected to include preliminary safety, pharmacokinetic (PK), and clinical activity data through cohort 6, as well as an analysis of circulating tumor DNA (ctDNA) data through cohort 5.

THE-630 is a pan-variant tyrosine kinase inhibitor (TKI) of the receptor tyrosine kinase KIT, designed for patients with GIST that have developed resistance to earlier lines of therapy. The primary objectives of the phase 1 dose escalation portion of the study are to evaluate the safety profile of THE-630, including the determination of a recommended phase 2 dose (RP2D) in GIST patients who have received imatinib and at least one other TKI. Secondary objectives include determining the PK profile of THE-630, and to characterize preliminary evidence of antitumor activity.

Virtual Investor Event

Theseus will host a virtual investor event to review these new data on Thursday, May 25, 2023, beginning at 5:30pm ET. The event will be webcast live and can be accessed in the Events section of the Company’s investor relations website at ir.theseusrx.com. A replay of the webcast will be archived and available for 30 days following the event.

"We are looking forward to sharing updated results from our ongoing studies evaluating GC012F in relapsed/refractory multiple myeloma and B-cell non-Hodgkin’s lymphoma. We are particularly encouraged by the recognition of our long-term follow-up data of GC012F in RRMM, which will be presented at an oral session. We believe for these hematological cancers, there is critical need for transformational treatment options with strong efficacy, favorable safety profiles and rapid manufacturing," said Dr. Wendy Li, Gracell’s Chief Medical Officer. "With plans to commence clinical trials in the U.S. and China following the receipt of regulatory clearance of Investigational New Drug applications, 2023 is a critical year for both GC012F and Gracell. We plan to showcase the latest data to our peers in cancer research at the ASCO (Free ASCO Whitepaper) Annual Meeting that augments the clinical validation of the FasTCAR platform in a wide array of indications, emphasizing the importance of the dual-targeted approach and the potential benefits of enhanced T cell quality and accelerated delivery of the therapy to patients thanks to Gracell’s FasTCAR next-day manufacturing technology."

BCMA/CD19 Dual-Targeting FasTCAR-T GC012F for the Treatment of RRMM

Longer-term follow-up data from a multicenter investigator-initiated trial evaluating GC012F for the treatment of RRMM in heavily pretreated patients will be presented as an oral abstract session.

Oral presentation details are as follows:

Abstract title: Updated results of a phase I, open-label study of BCMA/CD19 dual-targeting fast CAR-T GC012F for patients with relapsed/refractory multiple myeloma (RRMM)
Abstract number: 8005
Session title: Hematologic Malignancies – Plasma Cell Dyscrasia

About GC012F

GC012F is Gracell’s FasTCAR-enabled BCMA/CD19 dual-targeting autologous CAR-T cell therapy, which aims to transform cancer treatment by driving fast, deep and durable responses with improved safety profile. GC102F is currently being evaluated in investigator-initiated trials in multiple myeloma and B-cell non-Hodgkin’s lymphoma (B-NHL), and has demonstrated a consistently strong efficacy and safety profile. In February 2023, Gracell announced regulatory clearance of Investigational New Drug applications in the U.S. and China to commence clinical trials evaluating GC012F for the treatment of relapsed/refractory multiple myeloma.

About FasTCAR

Introduced in 2017, FasTCAR is Gracell’s revolutionary next-day autologous CAR-T cell manufacturing platform. FasTCAR is designed to lead the next generation of cancer therapy and improve outcomes for patients by enhancing efficacy, reducing costs, and enabling more patients to access critical CAR-T treatment. FasTCAR drastically shortens cell production from weeks to overnight, potentially reducing patient wait times and probability for their disease to progress. Furthermore, FasTCAR T-cells appear younger and are more robust than traditional CAR-T cells, making them more proliferative and effective at killing cancer cells. In November 2022, FasTCAR was named the winner of the Biotech Innovation category of the 2022 Fierce Life Sciences Innovation Awards for its ability to address major industry obstacles.

About EO-3021

EO-3021 (also known as SYSA1801) is a differentiated, clinical-stage antibody drug conjugate (ADC) comprised of an immunoglobulin G1 (IgG1) monoclonal antibody (mAb) that targets Claudin 18.2 and is site-specifically conjugated to the monomethyl auristatin E (MMAE) payload via a cleavable linker with a drug-to-antibody ratio (DAR) of 2. Claudin 18.2 is a specific isoform of Claudin 18 that is only expressed in gastric epithelial cells. During malignant transformation in many solid tumors, the tight junctions may become disrupted, exposing Claudin 18.2 and allowing them to be accessible by Claudin 18.2 targeting agents. An Investigational New Drug application for EO-3021 has been cleared by the U.S. Food and Drug Administration.
