Primary Outcome Measures:
  • Safety and tolerability of AC220 given once daily without food continuously for 28 days (1 cycle) to patients with advanced solid tumors. [ Time Frame: Repeatedly measured at multiple timepoints during 1st cycle; every 2 weeks thereafter ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Pharmacokinetic (PK) and pharmacodynamic (PD) parameters of AC220 in this patient population under the conditions of the study, including a careful and detailed evaluation of the ECG effects of AC220 in relation to plasma drug concentration [ Time Frame: Repeatedly measured at multiple timepoints during the first cycle of treament. ] [ Designated as safety issue: Yes ]
  • Preliminary evidence of antitumor biology or clinical activity of AC220 in patients enriched for diseases whose pathophysiology is directly related to aberrant c-KIT receptor or platelet-derived growth factor receptor signaling. [ Time Frame: Measured every 28 days (per treatment cycle) ] [ Designated as safety issue: No ]

  Eligibility

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

Inclusion Criteria:

  1. Males and females age ≥18 years
  2. Understand and voluntarily sign the informed consent form for this study
  3. Available for periodic follow-up at the investigative site
  4. Able to swallow the liquid study drug
  5. ECOG performance status of 0 - 2
  6. Histological diagnosis of a primary solid tumor malignancy that meets the following criteria:

    • Evidence (radiographic or tissue confirmation) that the disease is metastatic (locally advanced disease is allowable only if no surgical or local therapeutic option exists); and
    • Disease which has progressed on or following currently available standard therapies or for which no curative therapy exists (Prior adjuvant, neoadjuvant, and investigational therapies are permitted.)
  7. Measurable disease by computer tomography (CT) or magnetic resonance imaging (MRI) scans per RECIST.
  8. Prior anticancer therapy, radiotherapy, hormonal, and immunotherapy are allowed. Patients must have recovered from toxicity of prior therapy (ie, toxicity has resolved to Grade 1, or to pre-treatment baseline, or is deemed irreversible). At least 4 weeks must have elapsed since the last systemic therapy (6 weeks for nitrosoureas, mitomycin-C, and liposomal doxorubicin), immunotherapy, or radiotherapy and the beginning of study drug administration. For participants with GIST on approved tyrosine kinase inhibitors (TKI), at least 2 weeks must have elapsed since the last dose of TKI.
  9. Adequate bone marrow function, defined as:

    • Absolute neutrophil count (ANC) (neutrophils and bands) ≥1.5 x 10^9 cells/L
    • Platelet count ≥ 100 x 10^9 cells/L
    • Hemoglobin ≥ 9.0 g/dL
  10. Adequate hepatic function, defined as:

    • Total serum bilirubin ≤ 1.5 x the institutional upper limit of normal (ULN)
    • Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 x the institutional ULN
  11. Adequate renal function, defined as:

    • Serum creatinine ≤ 1.5 x the institutional ULN
  12. Prothrombin time or partial thromboplastin time (PT- PTT) ≤ 1.5 x the ULN
  13. Serum potassium, magnesium, and calcium levels should be at least within institutional normal limits, and every effort should be made to keep potassium concentrations above 4.0 mEq/dL, magnesium concentrations above 1.8 mg/dL, and serum calcium at normal concentration with the administration of oral/IV potassium and/or magnesium and/or calcium replacement during the study. If this is not possible, potassium and magnesium (and calcium) concentrations should at least be kept within institutional normal limits.
  14. Fully recovered (≤ Grade 1 or returned to baseline or deemed irreversible) from the acute effects of prior cancer therapy before initiation of study drug administration.
  15. Baseline left ventricular ejection fraction (LVEF) ≥ 45% (or ≥ institutional lower limit of normal if institutional lower limit of normal is below 45%) as assessed by 2-dimensional ECHO or MUGA as per institutional practice. If repeat LVEF assessment is required, the same modality should be used throughout the duration of study, whenever possible.
  16. Women of childbearing potential (WOCBP) must be using an adequate method of contraception to avoid pregnancy throughout the study and for at least 3 months after the study in such a manner that the risk of pregnancy is minimized. WOCBP includes any female who has experienced menarche and who has not undergone successful surgical sterilization (hysterectomy, bilateral tubal ligation or bilateral oophorectomy) or is not post menopausal (defined as amenorrhea > 12 consecutive months; or who is on hormone replacement therapy [HRT] with documented serum follicle stimulating hormone [FSH] level > 35 mIU/mL). Additionally, premenopausal women who are using oral, implanted or injectable contraceptive hormones or mechanical products such as an intrauterine device or barrier methods (diaphragm, condoms, spermicides) to prevent pregnancy, are practicing abstinence, or whose partner is sterile (eg, vasectomy), should be considered to be of childbearing potential.
  17. WOCBP must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin [hCG]) within 72 hours prior to the start of study drug.

Exclusion Criteria:

  1. WOCBP who are unwilling or unable to use an acceptable contraceptive method to avoid pregnancy for the entire study period and for at least 3 months after the study.
  2. Women who are pregnant or breastfeeding
  3. WOCBP with a positive pregnancy test on enrollment prior to study drug administration
  4. Men who are unwilling or unable to use an acceptable method of birth control if their sexual partners are WOCBP for the entire study period and for at least 3 months after completion of the study
  5. Patients with known untreated, symptomatic or uncontrolled brain or central nervous system (CNS) metastases. Patients with treated brain or CNS metastases that are radiographically stable for 3 months or longer are eligible.
  6. A serious uncontrolled medical disorder or active infection which would impair the ability of the patient to receive study drug
  7. Uncontrolled or significant cardiovascular disease, including:

    • A myocardial infarction within 12 months prior to study entry
    • Uncontrolled angina within 6 months prior to study entry
    • Congestive heart failure (CHF) New York Heart Association (NYHA) class 3 or 4, or patients with history CHF NYHA class 3 or 4 in the past, unless the screening ECHO or MUGA within 14 days prior to study entry results in a LVEF that is ≥ 45% (or ≥institutional lower limit of normal)
    • Diagnosed or suspected congenital long QT syndrome
    • Any history of clinically significant ventricular arrhythmias (such as ventricular tachycardia, ventricular fibrillation, or Torsades de Pointes [TdP])
    • Prolonged QTc interval on pre-entry ECG (≥ 450 ms)
    • Any history of second or third degree heart block
    • Uncontrolled hypertension
    • Obligate need for a cardiac pacemaker
    • Complete left bundle branch block
    • Atrial fibrillation
  8. Known infection with human immunodeficiency virus (HIV)
  9. Known active hepatitis A, B, or C or other active liver disease
  10. Dementia or altered mental status that would prohibit the understanding or rendering of informed consent
  11. Investigational agents during or within 4 weeks prior to the start of study drug
  12. Use of drugs that are generally accepted to have a risk of causing prolonged QTc and/or TdP and/or are CYP3A4 inhibitors. Patients who have discontinued any of these medications must have a washout period of at least 5 days or at least 5 half-lives of the drug (whichever is greater) prior to the first dose of study drug and should not be allowed to take these medications during the study drug dosing.
  13. Medical condition, serious intercurrent illness, or other extenuating circumstance that, in the judgment of the Principal Investigator or Sponsor, could jeopardize patient safety or interfere with the objectives of the study.
