Brief Summary
Preliminary data demonstrate that irAEs induced by immune checkpoint blockade can be successfully treated with ECP (Apostolova et al. NEJM 2020). Therefore this retrospective analysis is launched to v...
Detailed Description
Immune checkpoint inhibitors (ICI) have improved the long-term survival of patients with metastatic tumors. However, approximately 50% of the patients treated with ICI develop serious immune-related a...

- Patients should have clinical and/or histological evidence of immune-related adverse events as follows:
- Colitis Diarrhea with increase of ≥4 stools over baseline No improvement after 72h treatment with at least 1 mg/kg BW/day prednisolone equivalent
- Hepatitis Alanine aminotransferase and/or aspartate aminotransferase ≥3x ULN if baseline was normal; or ≥3x baseline if baseline was abnormal No improvement after 72h treatment with at least 1 mg/kg BW/day prednisolone equivalent

- Previous or concurrent malignancies within the last 3 years of enrollment other than the disease for which checkpoint-inhibitor blockade was applied. Exceptions are adequately treated basal or squamous cell skin cancer, or any other cancer from which the subject has been disease-free for more than 3 years.
- Any condition that would, in the investigator's judgment, interfere with full participation in the study, including administration of study drug and attending required study visits; pose a significant risk to the subject; or interfere with interpretation of study data
- Known allergies, hypersensitivity, or intolerance of methoxypsoralen, excipients, or similar compounds, heparin or similar compounds
