             protocol

          -  Subjects must have histologically confirmed solid malignancy that is metastatic or
             unresectable

          -  The patient should have received all established therapies where there is a clear,
             superior available regimen available for the patient and the patient should have
             demonstrated progressive disease on or since completion of the last treatment regimen

          -  Patients must have measurable disease defined as lesions that can be accurately

          -  Patients must have prior CT scan images available for investigators to collect

          -  Patients must have available tumor molecular profiling from Clinical Laboratory

             encoded by CDKN2A; sequencing or fluorescence in situ hybridization (FISH)/chromogenic
             in situ hybridization (CISH) methods are acceptable; the investigators will consider
             analyses performed according to similar standards as applied by Foundation Medicine

             of the following listed below) prior to the study entry, for the duration of study
             participation and up to 3 months following completion of therapy; women of
             child-bearing potential must have a negative pregnancy test within 7 days prior to
             initiation of treatment and post-menopausal women must be amenorrheic for at least 12
             months to be considered of non-childbearing potential

               -  Acceptable contraception

                    -  Total abstinence from sexual intercourse (minimum one complete menstrual
                       cycle)

                    -  Vasectomized male subjects or vasectomized partner of female subjects

                    -  Double-barrier method (condoms, contraceptive sponge, diaphragm or vaginal

                    -  Additionally, male subjects (including those who are vasectomized) whose
                       partners are pregnant or might be pregnant must agree to use condoms for the

          -  Women that are pregnant or lactating are excluded from this study

          -  Subject has known active central nervous system (CNS) involvement; the subject has
             untreated brain or meningeal metastases; CT scans are not required to rule out brain
             or meningeal metastases unless there is a clinical suspicion of central nervous system
             disease; subjects with treated brain metastases that are radiographically or
             clinically stable for at least 4 weeks after therapy and have no evidence of
             cavitation or hemorrhage in the brain lesion(s) are eligible, providing that they are
             asymptomatic, and do not require corticosteroids (must have discontinued steroids at
             least 1 week prior to study drug administration)

          -  Subject has had major surgery within 28 days prior to study day 1

          -  Subject has proteinuria defined by the National Cancer Institute Common Terminology
             Criteria for Adverse Events (NCI CTCAE version [v] 4.0) grade > 1 at baseline as
             measured by a urine dipstick (2+ or greater) and confirmed by a 24 hour urine
             collection (>= 1 g/24 hrs); subjects may be re-screened if proteinuria is shown to be
             controlled with or without intervention

          -  Subject is taking any oral anticoagulant

          -  History of:

               -  Symptomatic congestive heart failure

          -  Subject is unable to swallow or absorb oral tablets normally

          -  Subject takes cytochrome P450, family 3, subfamily A (CYP3A) inhibitors within 3 days
             or inducers within 7 days prior to the study drug administration; any questions or
             clarifications of these determinations should be brought to the attention of the
             principal investigator (PI); the PI will make the final determination on when it is
             safe to initiate ABT-348 (ilorasertib) therapy under circumstances where the magnitude
             or relevance of possible CYP3A4 inhibitors/inducers is unclear in the protocol
