  3. For inclusion in Cohorts 3A and 3B patients should have histologically confirmed (at primary diagnosis) unresectable malignant (defined as metastatic disease, i.e. presence of chromaffin tissue in non-chromaffin organs) pheochromocytoma/paraganglioma, and RECIST defined progression should have been documented during a maximum of an 18-months period.
  4. Patients with an age 18 years old.
  5. Patients who are human leukocyte antigen (HLA)-A2 positive.
  6. Patients with an Eastern Cooperative Oncology Group (ECOG) performance status 2.

  2. Patients with prior treatment with immune check-point inhibitors
  3. Patients with prior exposure to EO2401.
  4. Patients treated with immunotherapy (meaning immunostimulatory or immunosuppressive therapy; beside excluded, or allowed, compounds per other inclusion/exclusion criteria specifications), radionuclide therapy, radiotherapy, cytoreductive therapy, or received treatment with any other investigational agent within 28 days before the first EO2401 administration.
  5. Patients with ACC with more than three organs involved by disease, combined with high ki-67 expression in tumor ( 20%), and unresectable primary tumor.
  6. Patients with ACC and uncontrolled cortisol secretion (according to the judgement of the treating physician).
  7. Patients with MPP and uncontrolled blood pressure (according to the judgement of the treating physician).
  8. Patients with abnormal laboratory values.
  9. Patients with persistent Grade 3 or 4 toxicities.
  10. Uncontrolled central nervous system (CNS) metastasis.
  11. Other malignancy or prior malignancy with a disease-free interval of less than 3 years
  12. Patients with clinically significant disease.
  13. Patients with suspected autoimmune or active autoimmune disorder or known history of an autoimmune neurologic condition (e.g. Guillain-Barr syndrome).

  19. Patients with a history of hypersensitivity to any excipient present in the pharmaceutical forms of the study treatments.
  20. Patients treated with herbal remedies with immunostimulating properties or known to potentially interfere with major organ function.
  21. Patients with known ongoing drug and alcohol abuse.
  22. Patients with known or underlying medical or psychiatric condition that, in the Investigator's opinion, would make the administration of study drug hazardous to the patient or obscure the interpretation of toxicity determination or AEs.
  23. Patients deprived of their liberty, under protective custody, or guardship.
