Study of ADI-PEG 20 in Patients With Advanced Melanoma

Completed · Phase 1/Phase 2

Conditions studied: Metastatic Melanoma, Skin Cancer, Neoplasm

In brief

This was a phase 1/2, open-label, dose-escalation study of arginine deiminase linked via succinimidyl succinate to polyethylene glycol of 20,000 molecular weight (ADI-PEG 20) in subjects with advanced melanoma. ADI-PEG 20 was administered intramuscularly (IM) at escalating doses weekly for 9 weeks (cycle 1) or 8 weeks (subsequent cycles). The primary objectives were to the establish the safety, tolerability, and clinical efficacy of ADI-PEG 20. Secondary objectives included evaluation of the metabolic activity by \[18F\]-fluorodeoxyglucose positron emission tomography (FDG PET), pharmacodynamics, correlation of immunogenicity with clinical response, and correlation of argininosuccinate synthetase (ASS) tumor expression with clinical response.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Histologically confirmed malignant melanoma, American Joint Committee on Cancer (AJCC) stage III (unresectable) or IV. Subjects with uveal and mucosal melanomas were eligible.
• Measurable disease using the Response Evaluation Criteria in Solid Tumors (RECIST).
• Pathology slides reviewed by the Memorial Hospital Department of Pathology or New York University (NYU) Department of Pathology for confirmation of melanoma diagnosis.
• Karnofsky performance status of 80% or more.
• Adequate organ and marrow function, as defined below:
• white blood cell count ≥ 3000/µL
• absolute neutrophil count ≥ 1500/µL
• platelet count ≥ 100,000/µL
• total bilirubin ≤ 2.5 x institutional upper limit of normal (ULN)
• lactate dehydrogenase ≤ 1.5 x institutional ULN
• albumin ≥ 3.0 mg/dL
• creatinine ≤ 2.0 mg/dL
• Expected survival of at least 3 months.
• Age ≥ 18 years.
• Able and willing to give valid written informed consent.

You may not qualify if…

• Receipt of chemotherapy, immunotherapy, or radiotherapy within 3 weeks prior to first dosing of study agent or lack of recovery from adverse events (AEs) due to agents administered more than 3 weeks earlier. For nitrosoureas, at least 6 weeks must have elapsed.
• Any other malignancy that required concomitant therapy.
• Any medical condition that could have made it difficult for the subject to complete the full course of treatments, at the discretion of the Principal Investigator or co-Principal Investigators.
• Metastatic disease to the central nervous system, unless treated and stable.
• Known human immunodeficiency virus (HIV) positivity.
• Mental impairment that may have compromised the ability to give informed consent and comply with the requirements of the study.
• Lack of availability for clinical follow-up assessments.
• Participation in any other clinical trial involving another investigational agent within 3 weeks prior to enrollment.
• Pregnant women or women who were nursing. Women of child-bearing potential and sexually active men must have used appropriate contraception during the course of this study. Women of child-bearing potential must not have been pregnant (negative β human chorionic gonadotropin within 2 weeks of treatment) or nursing during treatment.
• History of seizure disorder.
