Brief Summary:
This is a Phase II/III randomized, controlled, multicenter, open-label study designed to assess the safety, efficacy, and impact on quality of life of PEG Intron (MK-4031) and INTRON® A (MK-2958) and the pharmacokinetics of PEG Intron when given as adjuvant (after surgery) therapy in participants with resected (surgically removed) Stage III node-positive cutaneous melanoma.

Condition or disease Intervention/treatment Phase
Melanoma Biological: PEG-Intron Biological: INTRON A Phase 2 Phase 3

Detailed Description:
This study was closed to enrollment prematurely due to sub-optimal accrual. Participants who were enrolled prior to enrollment closure were allowed to continue to receive study drug; these participants were followed for safety only.

Biological: PEG-Intron
Polyethylene glycol (PEG)12000 Interferon alfa 2-b subcutaneous injection.
Other Name: peginterferon alfa-2b, SCH 54031, MK-4031

Experimental: INTRON A
Participants with stage III node positive cutaneous melanoma will receive intravenous INTRON A (20 million international units [MIU]/m^2/day, 5 days a week) for 4 weeks followed by subcutaneous INTRON A (10 MIU/m^2 three times per week) for 48 weeks post-surgery.

Primary Outcome Measures :
  1. Progression-free Survival (PFS) [ Time Frame: From time of randomization to time of progression or death (up to approximately 26 months) ]
    Progression-free survival time was defined as the time from the date of randomization to the date of disease progression or the date of death regardless of the cause. PFS was to be assessed by clinical observation, with recurrence documented by appropriate radiographic and histologic methods, and confirmed by Independent Central Review.

Secondary Outcome Measures :
  1. Overall Survival [ Time Frame: From time of randomization to time of death (up to approximately 26 months) ]
    Overall survival (OS) is the time from randomization to death due to any cause. Participants were to be followed for survival every 3 months. Participants without documented death at the time of the final analysis were to be censored at the date of the last follow-up. After the early termination of the study, participants were followed for safety only. Although the OS analysis is not in the clinical study report due to early termination of the study, an OS ad hoc analysis was requested by the FDA and is therefore presented in this outcome measure. Below table presents the median duration of survival for participants.

Inclusion Criteria:

  • Participants must have histologically documented primary cutaneous melanoma meeting one of the following staging criteria:

    • Primary melanoma of any stage in the presence of N1 regional lymph node metastases detected at elective lymph node dissection or sentinel node biopsy, with clinically inapparent regional lymph node metastasis (any pTN1M0).
    • Clinically apparent N1 or N2a regional lymph node involvement synchronous with primary melanoma of T1-4 (any pTN1-2aM0).
    • Regional lymph node recurrence at any interval after appropriate surgery for primary melanoma of any depth (any primary tumor [pT], r N1-2a M0).
  • Participants must have had all known disease completely resected with adequate surgical margins within 56 days prior to randomization into the study
  • Participants must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
  • Participants must have adequate hepatic, renal and bone marrow function as defined by the following parameters obtained within 14 days prior to initiation of study treatment:

    • Hematology: white blood cells (WBC) ≥3,000 cells/µL and hemoglobin ≥9 g/dL.
    • Renal and hepatic function: serum creatinine <2.0 mg/dL; aspartate aminotransferase (AST or SGOT) and alanine aminotransferase (ALT or SGPT) <2 times upper limit of laboratory normal (ULN); and serum bilirubin <2 times ULN
