SYDNEY, AUSTRALIA – 28 July 2023 – Immutep Limited (ASX: IMM; NASDAQ: IMMP) ("Immutep” or “the Company”), a clinical-stage biotechnology company developing novel LAG-3 immunotherapies for cancer and autoimmune disease, today announces the first patient has been enrolled and safely dosed in EFTISARC-NEO, the Phase II investigator-initiated trial of eftilagimod alpha (efti), a soluble LAG-3 protein and MHC Class II agonist, in combination with radiotherapy and the anti-PD-1 therapy KEYTRUDA® (pembrolizumab) for patients with soft tissue sarcoma. This chemo-free trial is the first to evaluate efti in a neoadjuvant setting.

Soft tissue sarcoma (STS), an orphan disease, represents a high unmet medical need with a poor prognosis. The incidence of STS varies in different regions, with approximately 23,400 cases annually and a crude incidence of 4.7 per 100,000 in Europe, according to the RARECARE project.
