Summary:

      A phase 1 dose-escalation trial to assess the safety, tolerability, and pharmacodynamics of
      PF-04691502 in adult cancer patients with solid tumors.
    

Eligibility criteria:

        Inclusion Criteria:

          -  Patients with a histologically or cytologically confirmed malignant solid tumor for
             which there is no currently approved treatment or which is unresponsive to currently
             approved therapies.

          -  Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) 0-1

          -  Female patients of childbearing potential must have a negative serum or urine
             pregnancy test within 72 hours of the first dose of PF-04961502, These patients or
             their partners must be surgically sterile or be postmenopausal, or must agree to use
             effective contraception while receiving trial treatment and for at least 3 months
             thereafter. Male patients or their partners must be surgically sterile or must agree
             to use effective contraception while receiving trial treatment and for at least 3
             months thereafter. The definition of effective contraception will be based on the
             judgment of the Principal Investigator or a designated associate

          -  Adequate Cardiac Function, including:

             12-Lead electrocardiogram (ECG) with normal tracing or non clinically significant
             changes that do not require medical intervention. QTc interval ≤470 msec and no
             history of Torsades des Pointes or other symptomatic QTc abnormality

        Exclusion Criteria:

          -  Patients with known active brain metastases. Patients with previously diagnosed brain
             metastases are eligible if they have completed their CNS treatment and have recovered
             from the acute effects of radiation therapy or surgery prior to the start of study
             medication, have discontinued corticosteroid treatment for these metastases for at
             least 4 weeks and are neurologically stable

          -  Chemotherapy, radiotherapy (other than palliative radiotherapy to lesions that will
             not be followed for tumor assessment on this study, ie, non target lesions),
             biological or investigational agents within 2 weeks of Baseline disease assessments

          -  Any surgery (not including minor procedures such as lymph node biopsy) within 4 weeks
             of Baseline disease assessments; or not fully recovered from any side effects of
             previous procedures

          -  Prior therapy with an agent that is known or proposed to be active by action on PI3K
             and/or mTOR

          -  Prior high-dose chemotherapy requiring hematopoetic stem cell transplantation within
             12 months of study treatment start

          -  Uncontrolled or significant cardiovascular disease:

        A myocardial infarction within 12 months Uncontrolled angina within 6 months Congestive
        heart failure within 6 months. Diagnosed or suspected congenital long QT syndrome. Any
        history of ventricular arrhythmias (such as ventricular tachycardia, ventricular
        fibrillation, or Torsades de pointes). Any history of second or third degree heart block
        (may be eligible if currently have a pacemaker) Heart rate <50/minute on pre-entry
        electrocardiogram Uncontrolled hypertension.

          -  Current use or anticipated need for food or drugs that are known potent CYP3A4
             inhibitors or inducers

          -  Current use or anticipated need for food or drugs that are known potent CYP1A2
             inhibitors or inducers

          -  Concurrent administration of herbal preparations

          -  Breast feeding: No studies have been conducted in humans to assess the impact of
             PF-04691502 on milk production, its presence in breast milk and its effects on the
             breast-fed child. Because drugs are commonly excreted in human milk and because of the
             potential for serious adverse reactions in nursing infants, lactating female patients
             are excluded from this study.

          -  Any clinically significant gastrointestinal abnormalities, which may impair intake,
             transit or absorption of the study drug, such as the inability to take oral medication
             in tablet form and malabsorption syndrome.

          -  Any mental disorder that would limit the understanding or rendering of informed
             consent and/or compromise compliance with the requirements of this protocol
