— Previously reported Phase 1/2 data on WU-CART-007 demonstrated clinically manageable safety and evidence of anti-leukemic activity with an overall response rate of 91% and composite complete remission rate of 73% in heavily pretreated patients with R/R T-ALL/LBL — The global pivotal Phase 2 T-RRex Study will evaluate WU-CART-007 in pediatric and adult patients ST. LOUIS, MO, USA I March 20, 2025 I Wugen, Inc., a clinical-stage U.S. biotechnology company developing allogeneic, off-the-shelf cell therapies for the treatment of hematological and solid tumor malignancies, today announced the dosing of the first patients in its pivotal Phase 2 study evaluating WU-CART-007, a potential first-in-class, investigational, anti-CD7 CAR-T cell therapy for pediatric and adult patients with relapsed or refractory (R/R) T cell acute lymphoblastic leukemia or T cell lymphoblastic lymphoma (T-ALL/LBL). “The data we have previously reported from our Phase 1/2 study on the WU-CART-007 program has paved the way for the initiation of this pivotal study, and suggests it has the potential to set a new standard of care for relapsed or refractory T-ALL/LBL,” said Kumar Srinivasan, Ph.D., M.B.A., president and chief executive officer of Wugen. “The program has earned multiple U.S. Food and Drug Administration accelerated approval pathway designations, including RMAT, Fast Track, Orphan Drug, and Rare Pediatric Disease, as well as Priority Medicines designation in the EU. With this pivotal study now underway, we are advancing toward a much-needed off-the-shelf CAR-T option for patients who face historically poor outcomes and limited treatment alternatives.” Wugen previously announced positive results from a Phase 1/2 cohort expansion study showing clinically manageable safety and evidence of anti-leukemic activity (overall response rate of 91%; composite complete remission rate of 73%) in heavily pretreated patients with R/R T-ALL/LBL. Results were presented at both the American Society of Hematology Annual Meeting (ASH) in December of 2024 and the European Hematology Association (EHA) 2024 Hybrid Congress in June of 2024. “It’s been 20 years since a new medicine was approved for patients with relapsed or refractory T-ALL/LBL, which remain challenging hematologic malignancies with limited treatment options in the relapsed or refractory setting,” said Cherry Thomas, M.D., chief medical officer of Wugen. “WU-CART-007 has shown clinical response and manageable safety, making it a promising off-the-shelf cell therapy candidate to fill a longstanding treatment gap. The enthusiasm around the program and the need for new treatments have been reflected in the study recruitment thus far, as it is enrolling faster than anticipated.” Pivotal Study Design: The pivotal study entitled, “A Phase 2 Study of WU-CART-007, an Anti-CD7 Allogeneic CAR-T Cell Therapy in Patients with Relapsed or Refractory T-Cell Acute Lymphoblastic Leukemia and Lymphoblastic Lymphoma”, (T-RRex) is a single arm trial evaluating the efficacy and safety of WU-CART-007 in patients with R/R T-ALL/LBL and T-ALL/LBL. The study will involve two groups: a R/R cohort and subsequently an exploratory minimal residual disease (MRD)-positive cohort. About WU-CART-007 WU-CART-007 is an allogeneic, off-the-shelf, fratricide-resistant CD7-targeted CAR-T cell therapy engineered to overcome the technological challenges of harnessing CAR-T cells to treat CD7+ hematological malignancies. Wugen is deploying CRISPR/Cas9 gene editing technology to delete CD7 and the T cell receptor alpha constant (TRAC), preventing CAR-T cell fratricide and mitigating the risk of graft-versus-host-disease (GvHD). WU-CART-007 is manufactured using healthy donor-derived T cells to eliminate the risk of malignant cell contamination historically observed in the autologous CAR-T setting. WU-CART-007 is currently being evaluated in a global Phase 1/2 clinical trial for the treatment of relapsed or refractory (R/R) T cell acute lymphoblastic leukemia (T-ALL)/lymphoblastic lymphoma (LBL). More information on the Phase 1/2 trial is available on clinicaltrials.gov, identifier NCT# 04984356 and on the Phase 2 pivotal trial on clinicaltrials.gov, identifier NCT06514794. WU-CART-007 has received Regenerative Medicine Advanced Therapy (RMAT), Fast Track, Orphan Drug, and Rare Pediatric Disease designations from the U.S. Food and Drug Administration and Priority Medicines (PRIME) Scheme designation in the European Union for the treatment of relapsed/refractory (R/R) T cell acute lymphoblastic leukemia (T-ALL) and T cell lymphoblastic lymphoma (T-LBL). RMAT and PRIME designations provide increased agency support to expedite the development and review of promising therapies for patients in need.

BOSTON, MA, USA I March 5, 2025 I Bioheng Therapeutics US LLC (“Bioheng”), a clinical-stage biotech company dedicated to developing innovative universal CAR-T cell therapies, today announced that the U.S. Food and Drug Administration (FDA) has approved its Investigational New Drug (IND) application for CTD402, a CD7-targeted universal CAR-T (UCAR-T) cell therapy, for the treatment of pediatric and adult patients with relapsed/refractory T-cell acute lymphoblastic leukemia/lymphoma (R/R T-ALL/LBL). The study approved by the FDA is a single-arm, open-label Phase Ib/II trial with a simplified dose-finding design, designed to optimize dosing and accelerate clinical development. “We are delighted that CTD402 has received IND clearance from the U.S. FDA for a Phase Ib/II trial with a simplified dose-finding design, accelerating our clinical development timeline in the United States,” stated Jiangtao Ren, Ph.D., President & Chief Scientific Officer (CSO) of Bioheng. “IIT study results showed an impressive ORR, alongside a favorable safety profile. These results validate our ANSWER ® platform’s ability to deliver both rapid therapeutic impact and reduced patient risk, positioning CTD402 as a potential best-in-class therapy for T-cell malignancies.” About CTD402 CTD402 is a universal CAR-T cell product targeting CD7 derived from healthy donors and intended for the treatment of T-ALL/LBL. It is genetically modified to avoid fratricide, graft-versus-host disease (GvHD), and host-versus-graft rejection (HvG) while enhancing anti-tumor activity. CTD402 can be prepared in a single batch for multiple people, achieving an “off-the-shelf” capability for patients in need of CAR-T cell therapy. About T-ALL/LBL T-ALL/LBL are distinct clinical presentations of the same malignancy, originating from immature T-cell lineage lymphoid cells and classified based on the degree of bone marrow involvement. [1] While frontline therapy achieves high complete remission (CR) rates, the majority of patients ultimately experience relapse. Relapsed or refractory (R/R) disease is associated with poor outcomes, with a 5-year overall survival (OS) rate of less than 20%. [2] About Bioheng Bioheng Therapeutics is a clinical-stage company focused on allogeneic “off-the-shelf ” universal CAR-T therapies. Founded in 2017, we aim to develop the world’s leading allogeneic cell therapy platforms and products to address some of the most challenging unmet needs.
