Temozolomide and Survivin Long Peptide Vaccine (SurVaxM) for the Treatment of Patients With Progressing Metastatic Neuroendocrine Carcinomas

Korábbi kezelés

• Patients who have received temozolomide in the advanced disease setting either alone or as part of a combination therapy will be excluded if they progressed while on it
• Has received prior treatment with SurVaxM
• Received an investigational agent within 30 days prior to enrollment
• Participants who have received checkpoint inhibitors within 3 months prior to study enrollment or, those who have not recovered from adverse events due to agents administered more than 4 weeks earlier
• Systemic corticosteroid therapy > 2mg of dexamethasone or equivalent per day at study entry

Más betegség

• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, bradycardia, tachycardia or psychiatric illness/social situations that would limit compliance with study requirements and, which in the treating physicians' opinion would jeopardize the ability of the patient to receive the treatment outlined in this protocol with reasonable safety
• Patients with a concurrent or prior malignancy are ineligible unless they are patients with curatively treated carcinoma-in-situ or basal cell carcinoma of the skin. Patients who have been free of disease (any prior malignancy) for at least 3 years are eligible for this study
• Known history of an autoimmune disorder
• Known human immunodeficiency virus (HIV) positivity or acquired immunodeficiency syndrome (AIDS) related illness or other serious medical illness
• Any condition which in the Investigator's opinion deems the participant an unsuitable candidate to receive study drug
• Patients with Hepatitis B or Hepatitis C may be included if there are adequately controlled viral titers and no drug-drug interactions, testing not required

Egyéb
