ST. LOUIS and SAN DIEGO, June 14, 2024 (GLOBE NEWSWIRE) -- 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, announces positive Phase 2 results for the company's investigational anti-CD7 CAR-T therapy, WU-CART-007 (“W-T7”), in patients with relapsed/refractory (R/R) t-cell acute lymphoblastic leukemia/lymphoma (T-ALL/LBL).

In his presentation today at the European Hematology Association (EHA) 2024 Hybrid Congress in Madrid, lead investigator Ibrahim Aldoss, M.D., City of Hope in Duarte, CA, shared data from this Phase 2 cohort expansion study showing a clinically manageable safety profile as well as evidence of anti-leukemic activity with WU-CART-007 (“W-T7”) in patients with R/R T-ALL/LBL previously treated with existing therapies for their cancers.

“Relapsed and refractory T-ALL/LBL is a highly aggressive disease with high rates of relapse and mortality in both children and adults,” Dr. Aldoss said.“These results are exciting and support the potential of this allogeneic CAR-T as a new treatment for patients who still face a refractory illness despite having received the best medicines we have for T-ALL/LBL right now.”

“The need for effective, allogeneic treatments that are available at the point of care without delays is urgent for patients with hard-to-treat blood cancers,” said Wugen Chief Medical Officer Jan Davidson-Moncada, M.D., Ph.D.“Wugen is confident we can overcome specific challenges that have existed for CAR-T therapies in targeting T-cell diseases. We are eager to conduct further studies of WU-CART-007, which was invented by Wugen's Co-founder and Chief Scientific Officer Matt Cooper, Ph.D., to target CD7+ malignancies.”

Key Phase 2 Findings
The presentation at EHA featured results with the recommended dose (RP2D) of WU-CART-007 administered in 13 patients at a median age 30 years who were heavily pre-treated and had a high burden of disease at the start of the study. A substantial proportion of patients (38%) had progressed or relapsed after allogeneic stem cell transplant.

Outcomes following WU-CART-007 treatment in the study surpassed current standard of care1 for R/R T-ALL/LBL and included:

  • Composite complete remission rate (CRc) of 73% (8/11) (primary endpoint).
  • Overall response rate of 91% (10/11; 2 partial response (PR) in patients with extramedullary disease, R/R T-LBL).
  • Duration of response (DOR) (secondary endpoint):
    • Median duration (mDOR) was 6.2 months (95% CI: 1.8, NE);
    • Median follow up was 8.5 months (95% CI: 2.7, NE); 46% (5/11) patients remained in continuous remission at 4.3 to 8.6 months.
  • Seven patients (5 at RP2D) successfully transplanted.

Pharmacokinetic analysis exhibited rapid expansion and persistence of an allogeneic cell therapy:

  • At RP2D, WU-CART-007 expansion peaked at Day 10 (223,799 copies/g of DNA) and can be detected out to Day 90.
    • No patient developed drug product-specific anti-HLA antibodies.
    • No anti-drug antibody detected on any patients to date.

Phase 1 dose escalation data from this first-in-human global Phase 1/2 clinical trial of WU-CART-007 for the treatment of relapsed or refractory (R/R) T-cell acute lymphoblastic leukemia (T-ALL)/lymphoblastic lymphoma (LBL) were presented last December at the American Society of Hematology meeting.

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). Additional information is available on, identifier NCT# 04984356.

WU-CART-007 has received Orphan Drug, Fast Track, Rare Pediatric Disease and Regenerative Medicine Advanced Therapy (RMAT) designations from the U.S. Food and Drug Administration and received PRIME (“Priority Medicines”) 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.

About WU-NK-101
WU-NK-101 is a novel immunotherapy harnessing the power of memory natural killer (NK) cells to treat liquid and solid tumors. Memory NK cells are hyper-functional, long-lasting immune cells that exhibit enhanced anti-tumor activity and a cytokine-induced memory-like (CIML) phenotype. This cell population has a superior phenotype, proliferation capacity, and metabolic fitness, making it better suited for cancer therapy than other NK cell therapies. Wugen is applying its proprietary MonetaTM platform to advance WU-NK-101 as a commercially scalable, off-the-shelf cell therapy for cancer. WU-NK-101 is currently in development for acute myelogenous leukemia (AML). Wugen is planning to initiate solid tumor studies of WU-NK-101 in combination with cetuximab. Studies of WU-NK-101 to date have shown promising robust in vivo activity in various tumor indications, retention of anti-cancer activity in TME, resistance to immune suppression, and enhanced activity with checkpoint inhibitors. WU-NK-101 has received Orphan Drug Designation from the U.S. Food and Drug Administration for the treatment of AML.
