This is a phase 1, open-label pharmacokinetic study where up to 40 subjects with advanced solid tumors (up to 6-10 with normal renal function and up to 18-30 with varying degrees of renal dysfunction) will receive weekly doses of AMG 386 intravenously. The primary objective is to evaluate the pharmacokinetics (PK) of single agent AMG 386 in subjects with various degrees of renal function. Once the AMG 386 PK characterization is complete in the first 5 weeks of the study, all subjects will be allowed to continue to receive AMG 386 weekly only or subjects in group 1, 2 or 3 can opt to receive AMG 386 weekly in combination with paclitaxel until disease progression, unacceptable toxicity or withdrawal of consent.

Adverse events as a measure of safety
Time frame: Weekly at each visit AMG 386 is administered, on day 30, 31 and 32 when only PK assessments are scheduled up to and including the last study visit 30 days after the last AMG 386 administration.
Changes in vital signs as a measure of safety
Time frame: Weekly at each visit AMG 386 is administered up to and including the last study visit 30 days after the last AMG 386 administration.
Changes in clinical laboratory tests as a measure of safety
Time frame: Weekly from week 1-9 then every 4 weeks thereafter including the last study visit 30 days after the last AMG 386 administration.
Anti-AMG 386 antibody formation
Time frame: Week 1, week 5, week 9 and every 16 weeks thereafter including the last study visit 30 days after the last AMG 386 administration.
Tumor objective response measured by CT or MRI (without Gadolinium contrast agents) and assessed by RECIST 1.1 criteria.
Time frame: Week 5 and every 8 weeks thereafter until the subject's end of participation in the study.
