Clinical trial: Safety Study of XL647 and XL147 Administered in Combination Daily in Adults With Solid Tumors

Summary: The purpose of this study is to determine the safety, tolerability, and highest safe doses of XL647 in combination with XL147 in adults with solid tumors. XL647 is a small molecule that potently inhibits multiple receptor kinases, including EGFR, VEGFR2 (KDR), and ErbB2. XL147 is a new chemical entity that inhibits PI3 Kinase. Inactivation of PI3K has been shown to inhibit growth and induce apoptosis (programmed cell death) in tumor cells.


Eligibility: Inclusion Criteria:
  -  The subject has a histologically confirmed solid tumor that is metastatic or unresectable and is no longer responding to therapies known to prolong survival or to other standard therapies, or has disease for which no standard therapy exists.

  -  The subject's weight is ≥ 50 kg.
  -  The subject has an Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2.
  -  The subject has a life expectancy of ≥ 3 months.
  -  The subject has adequate organ and marrow function.
  -  The subject has a fasting plasma glucose (FPG) < 120 mg/dL at screening.
  -  The subject is capable of understanding and complying with the protocol and has signed the informed consent document.
  -  Sexually active subjects (male and female) must agree to use accepted methods of contraception during the course of the study and for 3 months after the last dose of protocol drug(s).
  -  Female subjects of childbearing potential must have a negative pregnancy test at screening.
  -  Subjects in the MTD Expansion Cohort:
  -  Must have measurable disease per Response Evaluation Criteria in Solid Tumors (RECIST).
  -  Must have a histologically confirmed diagnosis of NSCLC (Stage IIIB or IV) OR a histologically confirmed diagnosis of metastatic breast cancer.
  Exclusion Criteria:
  -  The subject has received cytotoxic chemotherapy (including investigational cytotoxic chemotherapy) within 3 weeks (or nitrosoureas or mitomycin C within 6 weeks) before the first dose of XL647.

  -  The subject requires treatment with drugs known to be associated with torsades de pointes or significant QT interval prolongation.
  -  The subject has a serum potassium level or a serum magnesium level that falls outside the normal range.
  -  The subject has known brain metastases or a primary brain tumor.
  -  The subject has intercurrent illness including but not limited to ongoing or active infection.
  -  The subject is known to be positive for the human immunodeficiency virus (HIV).
  -  The subject is pregnant or breastfeeding.
  -  The subject has a previously identified allergy or hypersensitivity to components of the study treatment formulations
