NKGen Biotech To Present Updated Phase 1 Data on SNK02 Allogeneic NK Cell Therapy in Solid Tumors at the 6th Annual Allogeneic Cell Therapies Summit 2024

SANTA ANA, Calif., June 03, 2024 (GLOBE NEWSWIRE) -- NKGen Biotech, Inc. (NASDAQ:NKGN) ("NKGen" or the "Company"), a clinical-stage biotechnology company focused on the development and commercialization of innovative autologous, allogeneic and CAR-NK natural killer ("NK") cell therapeutics, today announced that Paul Y. Song, MD, Chairman and Chief Executive Officer of NKGen Biotech, will present details on their cryopreserved allogeneic NK cell therapy platform as well as updated Phase 1 data on its use in solid tumors without lymphodepletion at the 6th Annual Allogeneic Cell Therapies Summit to be held in Boston, MA, from June 10-12, 2024.

Dr. Song's presentation will detail the Company's novel allogeneic blood-derived NK cell therapy ("SNK02") commercial manufacturing and cryopreservation process, as well provide an update on their initial Phase 1 results using SNK02 to treat patients with advanced refractory solid tumors. Furthermore, Dr. Song will explore the potential benefits of eliminating pre-treatment lymphodepletion in patients undergoing SNK02 therapy, aiming to safeguard immune function and aid in recovery. Avoiding lymphodepletion before administering cancer treatment can provide many benefits including reduced toxicity, preservation of immune function, and potentially enhancing treatment efficacy. The presentation will also include a discussion on an unexpected discovery from the SNK02 Phase 1 trial, hinting at its possible applicability as a treatment for patients beyond cancer.

A copy of the presentation will be available on the Scientific Publications page of the Company's website at https://nkgenbiotech.com/ once the presentation has concluded. Previously disclosed Phase 1 data on the positive effects of SNK02 on advanced solid tumors, which may not be included in this conference presentation, can also be found on the Scientific Publications page.
