AMG 172 First in Human Study in Patients With Kidney Cancer

Inclusion Criteria:

• Subjects must have a pathologically documented, definitively diagnosed, clear cell RCC that is relapsed/refractory following at least two lines of systemic therapy (one of which must be a tyrosine kinase), or the subject refuses standard therapy
• Measurable disease per RECIST 1.1 criteria. Subjects with non-measurable, but evaluable disease are also eligible for Part 1 of the study.
• Eastern Cooperative Oncology Group (ECOG) Performance Status of ≤ 1
• Willing to provide tumor samples and / or slides

• Hematological function, as follows:

  1. Absolute neutrophil count (ANC) ≥ 1.5 x 10^9/L;
  2. Platelet count ≥ 100 x 10^9/L;
  3. Hemoglobin > 9 g/dL
• Prothrombin time (PT) or partial thromboplastin time (PTT) < 1.5 x institutional upper limit of normal (IULN)

• Hepatic function, as follows:

  1. Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) < 3 x ULN;
  2. Total bilirubin < 1.5 x ULN (< 3.0 x ULN for subjects with documented Gilbert's Disease or for whom the indirect bilirubin level suggests an extrahepatic source of elevation);
  3. Alkaline phosphatase < 2 x ULN (< 5 x ULN in subjects whom the PI and sponsor agree that clinical data suggest extrahepatic source of elevation)
• Other inclusion criteria may apply

Exclusion Criteria:

• Known primary central nervous system (CNS) tumors or brain 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
• Clinically significant ECG changes which obscure the ability to assess the PR, QT, and QRS interval; congenital long QT syndrome
• A baseline ECG QTcF > 470 msec
• Known positive test for human immunodeficiency virus (HIV)
• Known acute or chronic hepatitis B or hepatitis C infection as determined by serologic tests
• Other exclusion criteria may apply
