High-Dose PEG-Intron Pharmacokinetic Study in Patients With Melanoma (Study P04831 AM2)

Phase 1

Completed

• Conditions: Melanoma
• Interventions: Drug: PEG-Intron

• Registration Number: NCT00457418
• Lead Sponsor: Merck Sharp & Dohme LLC

Brief Summary

The purpose of this study is to establish the pharmacokinetics of PEG-Intron, administered at a dose of 6 μg/kg/week for 8 weeks (induction treatment), followed by a dose of 3 μg/kg/week for up to 252 weeks (maintenance treatment), in patients with high risk melanoma.

Exclusion Criteria

• Female subjects who are pregnant, intend to become pregnant, or are breastfeeding.

• Previous treatment with interferon alpha, chemotherapy or immunotherapy for melanoma.

• Ocular melanoma, or melanoma of the mucous membranes.

• Evidence of distant or non-regional lymph node metastases.

• In-transit melanoma, even if the lesion has been resected.

• Disease that cannot be completely surgically resected.

• Lack of recovery from recent surgery.

• Prior malignancy within the past 5 years, except surgically cured squamous cell carcinoma of the skin, successfully resected early stage cutaneous melanoma, or cervical carcinoma in situ.

• Severe cardiovascular disease.

• Thyroid dysfunction not responsive to therapy.

• Uncontrolled diabetes mellitus (in the opinion of the investigator).

• Active autoimmune disease.

• Active and/or uncontrolled infection.

• History of seropositivity for human immunodeficiency virus (HIV).

• Pre-existing psychiatric condition.

• Clinical diagnosis of substance abuse of one or more of the following drugs within the following timeframes (excluding time spent in detoxification, hospitalization or incarceration):

  • Alcohol, intravenous drug use, inhalational, psychotropics, narcotics, cocaine, prescription or over-the-counter drugs: within 1 year of the Screening visit.

  • Methadone, buprenorphine hydrochloride (HCl), and/or butorphanol tartrate: within 1 year of Screening visit, unless subject has drug screen negative for other (non-narcotic) drugs documented in the past year and repeated negative within 2 months of Screening visit.

  • Multi-drug abuse (2 or more substances in 16a and 16b): within 3 years of Screening visit.

  • Marijuana:

    • If historic use is deemed excessive by the principal investigator (or medically qualified individual), or is interfering with the subject's life, then the subject is not eligible and should not be screened.
    • If marijuana use is not deemed excessive by principal investigator and does not interfere with life, subject must discontinue any current use of marijuana prior to entry into study.

• Medical condition requiring chronic systemic corticosteroids.

• Known allergy to the drug substance or any of the excipients in the PEG-Intron formulation.

• Any situation or condition that, in the opinion of the investigator, may interfere with optimal participation in the study.

• Use of any investigational drugs within 30 days of study entry.

• Participation in other clinical studies of investigational treatments.

Group	Intervention	Description
PEG-Intron	PEG-Intron	6 ug/kg/week, SC (first 8 weeks) 3 ug/kg/week, SC (252 weeks \[weeks 9-260\], maintenance)

Primary Outcome Measures

Name	Time	Method
Observed Time to Achieve Cmax (Tmax) of PEG-Intron at 12 Weeks	Predose, and 24, 48, 72, 96, and 168 hours postdose at 12 weeks	Tmax was defined as time of maximum plasma concentration.
Apparent Clearance(CL/F) of PEG-Intron at 12 Weeks	Predose, and 24, 48, 72, 96, and 168 hours postdose at 12 weeks	CL/F was defined apparent clearance - the volume of plasma in the vascular compartment cleared of drug per unit of time and per kilogram of body weight by the processes of metabolism and excretion.
Area Under the Curve (AUC) of PEG-Intron at 12 Weeks	Predose, and 24, 48, 72, 96, and 168 hours postdose at 12 weeks	AUC was defined as the actual body exposure to drug after administration of a dose of the drug.
