Brief Summary

This study will evaluate the safety, tolerability, and pharmacokinetics of the combination of rhuMab 2C4(Perjeta) and capecitabine (Xeloda) in participants with advanced solid tumors that have progressed during or after standard therapy, or for which no standard therapy is available. Participants will be enrolled and evaluated for dose-limiting toxicities (DLTs) in escalating-dose cohorts in order to determine the maximum tolerated dose (MTD).

Conditions

Study Groups

RhuMab 2C4 + Capecitabine 1000 mg/m^2 (Level 2)

Participants will receive a single 1000-mg/m\^2 dose of oral (PO) capecitabine on Day -7 for pretreatment assessment. Capecitabine will then be administered on Days 1 to 14 of each 3-week cycle at a dose of 1000 mg/m\^2 twice daily, and rhuMab 2C4 will be given on Day 1 of each 3-week cycle as a fixed-dose 1050-mg IV infusion. The incidence of DLTs will be used to guide intrapatient dose modification, as well as subsequent enrollment.

Group Type: EXPERIMENTAL

Capecitabine

Intervention Type: DRUG

Participants will receive capecitabine on Days 1 to 14 of each 3-week cycle as 825, 1000, or 1250 mg/m\^2 PO twice daily. Treatment may continue until disease progression, unacceptable toxicity, or consent withdrawal.

RhuMab 2C4

Intervention Type: DRUG

Participants will receive rhuMab 2C4 on Day 1 of each 3-week cycle as 1050 mg via IV infusion. Treatment may continue until disease progression, unacceptable toxicity, or consent withdrawal.

RhuMab 2C4 + Capecitabine 1250 mg/m^2 (Level 3)

Participants will receive a single 1250-mg/m\^2 dose of PO capecitabine on Day -7 for pretreatment assessment. Capecitabine will then be administered on Days 1 to 14 of each 3-week cycle at a dose of 1250 mg/m\^2 twice daily, and rhuMab 2C4 will be given on Day 1 of each 3-week cycle as a fixed-dose 1050-mg IV infusion. The incidence of DLTs will be used to guide intrapatient dose modification, as well as subsequent enrollment.

Group Type: EXPERIMENTAL

Capecitabine

RhuMab 2C4

Intervention Type: DRUG

Participants will receive rhuMab 2C4 on Day 1 of each 3-week cycle as 1050 mg via IV infusion. Treatment may continue until disease progression, unacceptable toxicity, or consent withdrawal.
