A Study to Assess the Safety and Tolerability of ADI-PEG 20 Combined with Pemetrexed and Cisplatinin in Subjects with Tumors Requiring Arginine


About this study

The purpose of this study is to assess the safety and tolerability of ADI-PEG 20 combined with pemetrexed and cisplatin in patients with tumors requiring arginine such as advanced malignant pleural mesothelioma, advanced peritoneal mesothelioma (for dose escalation cohort only), non squamous non-small cell lung cancer (stage IIIB/IV), metastatic uveal melanoma, advanced liver cell cancer or recurrent high-grade glioma.

  • Adequate hematologic, hepatic, and renal function

Exclusion Criteria

  • Radiotherapy (except for palliative reasons), targeted therapy, or immunotherapy (except for uveal melanoma) the previous four weeks before study treatment
  • Ongoing toxic manifestations of previous treatments
  • Symptomatic brain or spinal cord metastases (patients must be stable for > 3 months post radiotherapy or surgery) for subjects with mesothelioma, NSCLC, uveal melanoma (excludes subjects with HCC or glioma)
  • Major thoracic or abdominal surgery from which the patient has not yet recovered
