New sites in New Jersey, New York, and Florida broaden geographic reach and increase access for patients participating in Phase 2 trial of troculeucel in moderate Alzheimer's disease.
SANTA ANA, Calif., May 19, 2026 (GLOBE NEWSWIRE) -- NKGen Biotech, Inc. (OTC: NKGN) ("NKGen" or the "Company"), a clinical-stage biotechnology company focused on the development and commercialization of innovative autologous and allogeneic natural killer ("NK") cell therapeutics, today announced the activation of three additional clinical trial sites in the United States for its ongoing Phase 2 study of troculeucel in moderate Alzheimer's disease.
The new sites include Rutgers Health in Newark, New Jersey, Alzheimer's Disease Research Center in Albany, New York, and K2 Medical Research in Orlando, Florida. Together, these additions expand the Company's U.S. clinical footprint and improve geographic access for patients in the Northeast and Southeast regions.
"With these newly activated sites, we are expanding access for patients who previously had limited proximity to an active study center," said Paul Y. Song, M.D., Chairman and Chief Executive Officer of NKGen Biotech. "In particular, the addition of sites in the Northeast helps address an important geographic gap, as many interested patients in that region previously would have needed to travel significant distances to participate."
The Company's Alzheimer's disease program has previously operated clinical trial sites primarily on the West Coast and in Orlando, Florida. The addition of the Northeast sites provides more convenient access for patients and referring physicians, supporting continued efforts to evaluate the investigational therapy in a broader patient population.
All three newly added sites are now active and available for patient screening and enrollment as part of the ongoing Phase 2 trial. The expanded site network is expected to enhance enrollment capacity and support continued patient recruitment across multiple regions of the United States.
"Expanding our clinical footprint is an important step as we continue to advance our Alzheimer's program," said Dr. Song. "Improving access to trial participation remains a key priority as we work to evaluate our investigational approach in a broader and more diverse patient population."
The Company noted that clinical trial enrollment is influenced by multiple factors, including patient eligibility and regional referral patterns. While the expanded site network is expected to enhance enrollment capacity, there can be no assurance regarding the timing or rate of patient recruitment.
Additional information on the trial, including contact details for the activated sites, can be found on ClinicalTrials.gov at: NCT06189963.
