About

This first-in-human study of AMG 900 will be conducted in two parts: dose escalation and dose expansion. The dose escalation part of the study is aimed at evaluating the safety, tolerability and PK of oral AMG 900 in subjects with advanced solid tumors. Up to 50 subjects may be enrolled in dose escalation. The dose expansion part of the study will consist of 42 subjects in three taxane-resistant tumor types. The dose of AMG 900 will be dependent upon data from the dose escalation part of the study

Full description

that G-CSF must be started at day 5, 1 day after the last day of AMG 900 and be continued until neutrophiles are > 1000 or until day 12, meaning 2 days before the reinduction.

Exclusion criteria

  • Active parenchymal brain metastases. Subjects who have had brain metastases resected or have received radiation therapy ending at least 4 weeks prior to study day 1 are eligible if they meet all of the following criteria: a) residual neurological symptoms grade < 1; b) no dexamethasone requirement; and c) follow-up MRI shows no new lesions appearing

  • Known positive test for HIV
  • Active 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 Common Terminology Criteria for Adverse Events (CTCAE) grade 0 or 1, or to levels dictated in the eligibility criteria with the exception of alopecia
  • Anti-tumor therapy within 28 days of study day 1; 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, corticosteroids, cyclosporine and tacrolimus within two weeks prior to enrollment
  • Therapeutic or palliative radiation therapy within two weeks of study day 1
  • Systemic anticoagulation therapy, including warfarin, within 28 days of day 1
  • Prior treatment with aurora inhibitors
