Format:	Poster Presentation

EFTISARC-NEO is the first to evaluate efti in a neoadjuvant setting, which importantly provides access to tumour tissue before and after treatment to assess efti’s impact on the tumour microenvironment. Initial efficacy data from this novel triple combination reported in May 2024 showed very encouraging results in the first six patients with the majority having deep responses rarely seen in STS patients with standard therapeutic approaches.

STS is an orphan disease with high unmet medical need and a poor prognosis for patients. The incidence of STS varies in different regions across Europe, with ~23,400 cases annually according to the RARECARE project. In the United States, the number of new STS cases in 2024 is estimated to be ~13,590 with ~5,200 deaths, according to the American Cancer Society.

The open-label EFTISARC-NEO Phase II study will treat up to 40 patients and is being conducted by the Maria Skłodowska-Curie National Research Institute of Oncology in Warsaw. The trial is primarily funded with an approved grant from the Polish government awarded by the Polish Medical Research Agency program. For more information, visit clinicaltrials.gov (NCT06128863).

Immutep will announce the data to the ASX and make the poster presentation available on the Posters & Publications section of Immutep’s website, after the presentation at CTOS 2024.
