Lirum Therapeutics Presents Positive Data on LX-101, a Novel Clinical-Stage Targeted Therapy, at the 2024 ESMO Targeted Anticancer Therapies Congress; Highlighting LX-101’s Potential in IGF-1R Prominent Cancers

New York, NY – February 26, 2024 – Lirum Therapeutics, Inc. (“Lirum”), an innovative clinical-stage biopharmaceutical company focused on the treatment of debilitating diseases, announced today that it will present positive data on LX-101, a novel clinical-stage targeted therapy directed to the insulin growth factor-1 receptor (IGF-1R), in patients with high IGF-1R tumor expression at the 2024 European Society for Medical Oncology (ESMO) Targeted Anticancer Therapies Congress in Paris, France on Monday, February 26th at 5:15 PM CET (11:15 ET).

Lirum’s presentation “LX-101, a novel, clinical-stage, payload-bearing IGF-1R targeted therapy demonstrates activity in patients with high IGF-1R tumor expression” will be presented in the Hall Bordeaux at the Palais des Congrès. The poster presentation covers patient outcomes in the previous Phase 1a studies with LX-101, with a focus on those patients that we determined to have high IGF-1R tumor expression. Of the 19 patients treated with LX-101, 4 were considered high IGF-1R expressers. Of these 4 patients, 3 were evaluable for response, and 2/3 (67%) of these patients experienced disease control/response, including the one patient who had an objective response at the highest dose. The poster presentation is available on the Lirum website ( under the Investors and Media tab.

Given the promising results, including that patients with high IGF-1R expressing tumors can be clinically sensitive to LX-101, Lirum is planning new clinical trials with LX-101 focused on oncologic indications, both pediatric and adult, that carry well-established ties to the IGF-1/IGF-1R pathway. Lirum is also developing LX-101 in certain autoimmune diseases, including thyroid dye disease, where IGF-1R has been clinically and commercially validated.
