LIXTE Biotechnology Holdings, Inc. (“LIXTE” or the “Company”) (Nasdaq: LIXT and LIXTW), a clinical stage pharmaceutical company, today announced it has added the Robert H. Lurie Comprehensive Cancer Center (Lurie Cancer Center) of Northwestern University as a second site in a clinical trial combining the Company’s proprietary compound LB-100 with GSK’s Dostarlimab to treat ovarian clear cell cancer.

Emily M. Hinchcliff, MD, MPH, will lead the clinical trial at Lurie Cancer Center, a renown Chicago-based National Cancer Institute-designated Comprehensive Cancer Center, which is located at Northwestern Memorial Hospital’s downtown medical campus. Patient recruitment is underway, and the first patient has been dosed.

“Clinical trials testing potentially effective therapies are essential to move our field forward, with many recent great successes,” said Dr. Hinchcliff. “We are pleased to be participating in this important clinical trial to assess whether adding LIXTE’s LB-100 to GSK’s Dostarlimab will enhance the effectiveness of immunotherapy in the treatment of ovarian clear cell carcinoma, a disease of high unmet need.”

Bas van der Baan, LIXTE’s Chief Executive Officer, said, “The addition of Lurie Cancer Center is a positive step in expanding the patient population and accelerating this clinical trial, which was initiated in January 2024 at The University of Texas MD Anderson Cancer Center. The trial is directed by lead clinical investigator Amir Jazaeri, MD, Professor of Gynecologic Oncology.”
