A Phase 1 Study of AMG 208 in Subjects With Advanced Solid Tumors

Inclusion Criteria:

- Men or women ≥ 18 years old

- Subjects must have a pathologically documented, definitively diagnosed, advanced
solid tumor that is refractory to standard treatment, for which no standard therapy
is available or the subject refuses standard therapy

disease are also eligible for Part 1 of the study)

- Eastern Cooperative Oncology Group (ECOG) Performance Status of ≤ 2

- Life expectancy of > 3 months, in the opinion of the investigator

- Female subjects who are post-menopausal (no menstrual period for a minimum of 12
months), or surgically sterilized. Female subjects of child bearing potential must
remain abstinent or use double-barrier birth control method during the period of
therapy and must be willing to use contraception 2 weeks following the last study
drug administration and have a negative serum pregnancy test upon entry into this
study

- Male subject is willing to use contraception upon enrollment, during the course of
the study and for 12 weeks following the last study drug administration

- Willing to provide tumor samples and / or slides

- Competent to sign and date an Institutional Review Board approved informed consent
form

- Hematological function, as follows:

Absolute neutrophil count (ANC) ≥ 1.5 x 109/L Platelet count ≥ 100 x 109/L Hemoglobin > 9
g/dL Prothrombin time (PT) or partial thromboplastin time (PTT) < 1.5 x institutional
upper limit of normal (IULN)

- Renal function, as follows:

Serum creatinine < 2.0 mg/dL

- Hepatic function, as follows:

AST/ALT < 3x ULN and total bilirubin < 1.5x ULN in all subjects Alkaline phosphatase < 2.0
x ULN (if liver or bone metastases are present, ≤ 5 x ULN)

Exclusion Criteria:

- Any disorder that compromises the ability of the subject to give written informed
consent and/or to comply with the study procedures.

- Primary central nervous system (CNS) tumors or metastases

- History of bleeding diathesis

- Myocardial infarction within 6 months of study day 1, symptomatic congestive heart
failure (New York Heart Association > class II), unstable angina, or unstable cardiac
arrhythmia requiring medication, or uncontrolled hypertension in the opinion of the
investigator

- A baseline ECG QTc > 480 ms

- Active infection within 2 weeks of study enrollment (day 1)

- Significant gastrointestinal disorder(s), in the opinion of the investigator, (e.g.
Crohn's disease, ulcerative colitis, extensive gastrointestinal resection) that may
influence drug absorption

- Known positive test for HIV

- Known acute or chronic hepatitis B or hepatitis C infection, determined by serologic
tests

- Unresolved toxicities from prior anti-tumor therapy, defined as not having resolved
to CTCAE grade 0 or 1, or to levels dictated in the eligibility criteria with the
exception of alopecia

- Anti-tumor therapy (chemotherapy, antibody therapy, molecular targeted therapy,
retinoid therapy, hormonal therapy, or investigational agent) within 28 days of study
day 1 (six weeks for nitrosureas, mitomycin C, or antibody or molecular targeted
agents with t1/2 > 10 days); concurrent use of hormone deprivation therapy for
hormone-refractory prostate cancer or breast cancer is permitted

- Treatment with immune modulators including, but not limited to, systemic
corticosteroids, cyclosporine and tacrolimus within two weeks prior to enrollment

- Therapeutic or palliative radiation therapy within 2 weeks of study day 1

- Concurrent or prior (within 7 days of study day 1) anticoagulation therapy (low-dose
warfarin [≤ 2 mg/day] or low molecular weight heparins for prophylaxis against
central venous catheter thrombosis or aspirin [81 mg/day] is allowed)

- Prior participation in an investigational study and/or procedure within 28 days of
study day 1

- Major surgery within 30 days of study day 1

- Any co-morbid medical disorder that may increase the risk of toxicity, in the opinion
of the investigator or sponsor
