    C2a/1vsC2a/2vsC3: median treatment duration 1.4vs3.2vs4.8 months, disease control rate 22%vs40%vs88%, median PFS 1.6vs3.6vs5.5 months; median survival 9.0vs12.6vstoo early (C3 median FU 8.3 mo, survival ongoing up to 2 years). Further follow-up will be presented.

    EO2401 (E) peptide immunotherapy + nivolumab (N) in adrenocortical carcinoma (ACC) and metastatic pheochromocytoma/paraganglioma (MPP): EOADR1-19/SPENCER (ESMO 2023)
    Post-hoc analyses identified predictors of lack of efficacy (no mitotane, ECOG > 1, ACC 1st diagnosis ≤9 months(mo), lesion size >125 mm, >3 organs involved, lymphopenia >grade 1); C2-post hoc group was created applying these factors. Conclusions EO2401/N was well tolerated generating durable immune responses correlating with efficacy. Based on the greater efficacy in C2-post hoc group a randomized extension is currently recruiting.

    EO2401, a novel microbiome-derived therapeutic vaccine for patients with recurrent glioblastoma: ROSALIE study. (EANO 2022)
    This ongoing Ph 1/2 trial (NCT04116658) investigates the safety and tolerability (primary) of EO (300 µg/peptide, SC Q2W X 4, then Q4W), EO with nivolumab (3 mg/kg Q2W; EN), and EN with bevacizumab (10 mg/kg Q2W; ENB) among four Cohorts (Cs) of pts with GB at first progression/recurrence after radiotherapy/temozolomide. EO2401 generated strong systemic immune responses and was well tolerated in combination with nivolumab ± bevacizumab. Preliminary ORR/DCR and mPFS for ENB, and survival for EN seem encouraging. Updated results from the current 40 patients and results from additional 35 patients who already started treatment with EN with the option for low-dose bevacizumab edema treatment at neurological symptoms will be presented.
