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.

Detailed description:

Arms:
arm 1: Participants receive PEG interferon alfa-2b 0.75 mcg/kg by subcutaneous (SC) injection OW for up to 40 weeks. They also receive 500 to 1000 mg of acetaminophen orally 30 minutes prior to PEG interferon alfa-2b administration, and 500 to 1000 mg afterwards every 4 to 6 hours as needed. Total daily dose of acetaminophen should not exceed 3000 mg. arm 2: Participants receive PEG interferon alfa-2b 1.5 mcg/kg by SC injection OW for up to 40 weeks. They also receive 500 to 1000 mg of acetaminophen orally 30 minutes prior to PEG interferon alfa-2b administration, and 500 to 1000 mg afterwards every 4 to 6 hours as needed. Total daily dose of acetaminophen should not exceed 3000 mg. arm 3: Participants receive PEG interferon alfa-2b 3 mcg/kg by SC injection OW for up to 40 weeks. They also receive 500 to 1000 mg of acetaminophen orally 30 minutes prior to PEG interferon alfa-2b administration, and 500 to 1000 mg afterwards every 4 to 6 hours as needed. Total daily dose of acetaminophen should not exceed 3000 mg. arm 4: Participants receive PEG interferon alfa-2b 4.5 mcg/kg by SC injection OW for up to 40 weeks. They also receive 500 to 1000 mg of acetaminophen orally 30 minutes prior to PEG interferon alfa-2b administration, and 500 to 1000 mg afterwards every 4 to 6 hours as needed. Total daily dose of acetaminophen should not exceed 3000 mg. arm 5: Participants receive PEG interferon alfa-2b 6 mcg/kg by SC injection OW for up to 40 weeks. They also receive 500 to 1000 mg of acetaminophen orally 30 minutes prior to PEG interferon alfa-2b administration, and 500 to 1000 mg afterwards every 4 to 6 hours as needed. Total daily dose of acetaminophen should not exceed 3000 mg. arm 6: Participants receive PEG interferon alfa-2b 7.5 mcg/kg by SC injection OW for up to 40 weeks. They also receive 500 to 1000 mg of acetaminophen orally 30 minutes prior to PEG interferon alfa-2b administration, and 500 to 1000 mg afterwards every 4 to 6 hours as needed. Total daily dose of acetaminophen should not exceed 3000 mg.

Interventions: intervention 1: PEG Interferon Alfa-2b intervention 2: Acetaminophen
Intervention descriptions: intervention 1: 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. intervention 2: 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.
