Expanded Access Study of Melphalan With Delcath CS-PHP System in Patients With Ocular/Cutaneous Melanoma Mets to Liver

The safety and efficacy of CS-PHP-melphalan has been evaluated in a phase 3 trial conducted in the same patient population as well as using the same melphalan dosing as proposed in this study. This expanded access protocol will provide an experimental alternative treatment option for both physicians and patients until the Delcath CS-PHP System receives marketing approval.


Eligibility Criteria:
Inclusion Criteria:

1.

   * a solitary metastasis to any site that can be resected with limited morbidity or controlled with radiation
2. ≥1 measurable hepatic lesion per RECIST 1.1
3. Vasculature compatible with insertion of CS-PHP catheters, per baseline abdominal MRA
4. ECOG PS 0-2

Exclusion Criteria:

1. Chemotherapy, radiotherapy, or biologic therapy for the malignancy ≤1 month prior to 1st CS-PHP-melphalan infusion
2. Extensive prior radiotherapy, defined as treatment to ≥50% of marrow-containing bones
