Tessa Therapeutics Announces Presentation of Autologous and Allogeneic Cell Therapy Data at 2021 ASH Annual Meeting

Presentations to feature clinical data from a Phase II CD30 CAR-T therapy study and a Phase I CD30 CAR-EBVST therapy study targeting lymphomas

SINGAPORE, Nov. 03, 2021 (GLOBE NEWSWIRE) -- Tessa Therapeutics Ltd. (Tessa), a clinical-stage cell therapy company developing next-generation cancer treatments for hematological malignancies and solid tumors, today announced that data from its ongoing autologous and allogeneic cell therapy studies targeting lymphomas has been accepted for two separate poster presentations at the 63rd American Society of Hematology (ASH) Annual Meeting and Exposition being held from December 11-14, 2021.

The presentations include clinical data from a Phase II multi-center study evaluating safety and efficacy of CD30 CAR-T therapy (TT11) in patients with relapsed / refractory classical Hodgkin Lymphoma (R/R cHL) and another Phase I investigator-initiated study testing allogeneic ‘off-the-shelf’ CD30 CAR EBVST therapy (TT11X) in patients with relapsed / refractory CD30+ lymphoma. Accepted abstracts will also be published online in the November supplemental issue of Blood, a publication of the American Society of Hematology.

About TT11 (CD30 CAR-T Therapy)

TT11 is a CAR-T therapy, which harvests a patient’s own T-cells and modifies them by introducing a CD30-directed Chimeric Antigen Receptor (CAR) to target and kill CD30+ cells in classical Hodgkin Lymphoma (cHL). CD30 is a well validated lymphoma target with homogeneous expression in 98% of cHL and a significant proportion of subsets of non-Hodgkin Lymphomas. Clinical data from two Phase 1/2 studies, published last year in the Journal of Clinical Oncologya, showed TT11 demonstrated strong safety and efficacy as a monotherapy for heavily pre-treated R/R cHL patients. A Phase 2 study was subsequently conducted this year evaluating TT11 among R/R cHL patients, results for which will be presented at 2021 ASH annual meeting.

About TT11X (Allogeneic CD30 CAR-EBVST Therapy)

TT11X is an allogeneic ‘off-the-shelf’ therapy which augments Epstein bar virus-specific T-cells with CD30 CAR technology. The therapy is based on a proprietary allogeneic cell therapy platform developed from decades-long research and development on unique properties of Virus Specific T-cells (VSTs) by Tessa’s Scientific Co-Founder, Dr. Malcolm Brenner, and the team at Baylor College of Medicine. VSTs are highly specialized T cells with the ability to recognize and kill infected cells while activating other parts of the immune system for a coordinated response. Allogeneic VSTs without any form of genetic modification have demonstrated a strong safety profile and efficacy in early trials with minimal risk of GVHD. Preclinical studies have further demonstrated that CD30 targeting potentially helps improve allogeneic cell expansion and persistence. With this platform approach, Tessa aims to overcome the current challenges faced by allogeneic cell therapies and create more efficacious, reliable, and scalable therapies capable of targeting a broad range of cancers.

About Tessa Therapeutics

Tessa Therapeutics is a clinical-stage biotechnology company developing next-generation cell therapies for the treatment of hematological cancers and solid tumors. Tessa’s lead clinical asset, TT11, is an autologous CD30 targeting CAR-T therapy currently being investigated as a potential treatment for relapsed or refractory classical Hodgkin lymphoma (Phase 2). TT11 has been granted RMAT designation by the FDA and PRIME designation by European Medicine Agency. Tessa is also advancing an allogeneic “off-the shelf” cell therapy platform targeting a broad range of cancers in which Epstein Barr Virus Specific T Cells (EBVSTs) are augmented with CD30-CAR technology to prevent graft rejection. A therapy using this platform is currently the subject of a Phase 1 clinical trial in CD30-positive lymphoma. A third clinical asset evaluates novel combination therapy of HER2-CAR-T cells and binary oncolytic virus in an ongoing Phase 1 study targeting HER2 positive solid tumors. Tessa has its global headquarters in Singapore, where the company has built a state of the art, commercial cell therapy manufacturing facility. Tessa’s United States headquarters are in New Jersey.
