Brief summary

This study is an extension study to base study protocol C/I97-188 (MK-4031-006). Its primary purpose is to assess the safety and tolerability of extended administration of polyethylene glycol (PEG) interferon alfa-2b in participants with solid tumors.

Interventions

Participants receive PEG interferon alfa-2b administered by SC injection, in doses ranging from 0.75 mcg/kg OW up to 7.5 mcg/kg OW, for up to 40 weeks of treatment.

DRUGAcetaminophen

Participants receive 500 to 1000 mg of acetaminophen orally 30 minutes prior to PEG interferon alfa-2b administration, and continue acetaminophen 500 to 1000 mg after administration every 4 to 6 hours as needed. The total daily dose of acetaminophen should not exceed 3000 mg.

MeasureTime frameDescription
Number of Participants Who Experienced an Adverse EventUp to 42 WeeksAn adverse event (AE) is any untoward medical occurrence in a study participant administered a pharmaceutical product that does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product, whether or not related to the medicinal product.

Secondary

MeasureTime frameDescription
Best Objective ResponseUp to 40 WeeksBest Objective Response data were based on World Health Organization (WHO) criteria and included four categories. Complete Response (CR) was the disappearance of all clinically detectable malignant disease. Partial Response (PR) was a decrease of ≥50% of the sum of products of largest perpendicular diameters of all bidimensionally measurable lesions; and a decrease of ≥50% in sum of largest diameters of all unidimensionally measure lesions. Stable Disease (SD) was a \<50% decrease or \<25% increase in sum of products of largest perpendicular diameters of all bidimensionally measurable lesions; or a \<50% decrease or \<25% increase in sum of diameters of all unidimensionally measurable lesions. In addition, no new lesions appeared. Progressive Disease (PD) was a ≥25% increase in size of at least one bidimensionally or unidimensionally measurable lesion or appearance of new lesion. Occurrence of pleural effusion or ascites was also considered PD if substantiated by positive cytology.

Number of Participants Who Discontinued Treatment Due to an Adverse Event

An adverse event (AE) is any untoward medical occurrence in a study participant administered a pharmaceutical product that does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product, whether or not related to the medicinal product.
