Abstract

4119Background: The therapeutic options for 2nd line therapy PDAC remain unsatisfying with 5-FU/LV plus oxaliplatin or nal-irinotecan resulting in a mOS of 5-6 mo. PDAC has been largely refractory to immune-oncology approaches and CD8+ T cells are rare in most PDAC. AM0010 stimulates survival, expansion and cytotoxicity of intratumoral CD8+ T cells. Immune activation, durable stable disease and a 1yr survival of 22.5% was seen in salvage PDAC patients (pts) receiving AM0010 alone. AM0010 has synergistic anti-tumor activity with 5-FU/LV or oxaliplatin in preclinical models. Here we report on the safety, efficacy and overall survival of AM0010 + FOLFOX as 2nd and later line treatment in PDAC pts. Methods: PDAC pts progressing on a median of 2 prior therapies (range 1-5) were treated with AM0010 (5ug/kg SQ, qd) + FOLFOX (n = 21). The safety population (n = 25) included also 4 pts with prior oxaliplatin / 5-FU. Tumor responses were assessed with irRC. The survival population included all patients without prio...
