Clinical Trial VICCTHO1429


An Open-label, Phase 1 Dose Escalation Study of Oral ASP8273 in Subjects with Non-Small-Cell Lung Cancer (NSCLC) Who Have Epidermal Growth Factor Receptor (EGFR) Mutations

Principal Investigator(s)

Leora Horn


  • Protocol No. VICCTHO1429
  • Open Date: 08/05/2014
  • Staging: Phase I
  • Age Group: Adults
  • Scope: National
  • Objective: - To assess the safety and tolerability of ASP8273. - To determine the maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D) based on dose limiting toxicities (DLT) of ASP8273.
  • Disease Sites: Lung; Non Small Cell
  • Therapies: Molecular Targeted Agents / Immunotherapy / Biologics
  • Drugs: ASP8273
  • Participating Institutions: Vanderbilt University
  • National Clinical Trial ID: NCT02113813
  • Secondary Protocol No: 8273-CL-0102


You are being asked to take part in this research study because you have advanced Non-Small Cell Lung Cancer (NSCLC). The purpose of this study is to assess the safety of ASP8273 and to determine a safe dose of the study drug in patients with advanced Non-Small Cell Lung Cancer (NSCLC). The information collected in this study is necessary to find out whether the treatment tested is effective and safe. The information about you will be kept anonymous. Information may be used for seeking approval from the regulatory authorities to market the medicine for NSCLC. It may also be used in reports of the study or for scientific presentations. Astellas may also use the information from this study for future medical research.


Ages Eligible for Study:18 Years and older
Genders Eligible for Study:Both
Accepts Healthy Volunteers:No
