Patients with known seizure disorder must have seizures adequately controlled with non- enzyme inducing antiepileptic medications Patients with seizure disorder may be enrolled if on non-enzyme inducing anticonvulsants and well controlled Patients with seizure disorder may be enrolled if receiving non-enzyme inducing anticonvulsants and well controlled Patients with seizure disorder may be enrolled if on non-enzyme inducing anticonvulsants and well controlled Patients who are currently receiving enzyme inducing anticonvulsants are not eligible Patients with seizure disorder may be enrolled if on non-enzyme inducing anticonvulsants and well controlled Anticonvulsants: patients on enzyme inducing anticonvulsants (EIAED) will be excluded; if patients were previously on EIAEDs that have been discontinued, patients must have been off EIAEDs for >= 2 weeks prior to initiation of dasatinib Patients with a seizure disorder may be enrolled if well-controlled and on non-enzyme inducing anticonvulsants Patients with seizure disorder may be enrolled if well controlled; patients receiving enzyme-inducing anticonvulsants are not eligible for this study; patients must be off enzyme inducing anticonvulsant drugs (EIACD) for at least 2 weeks prior to registration Patients on enzyme inducing anticonvulsants Concomitant use of any enzyme inducing anticonvulsants is not allowed Subjects with seizure disorder may be enrolled if on anticonvulsants and well controlled Patients with seizure disorder may be enrolled if on anticonvulsants and well controlled Patients with seizure disorder may be enrolled if on anticonvulsants and well controlled Treatment with non-enzyme inducing anti-seizure medications is allowed Central nervous system function defined as:\r\n* Patients with seizure disorder may be enrolled if on anticonvulsants and well controlled\r\n* Patients must not be in status, coma or assisted ventilation prior to study enrollment Brain metastases that are symptomatic or requiring corticosteroids (except inhaled); subjects must also be off of enzyme-inducing anticonvulsants for > 4 weeks Central nervous system function defined as\r\n* Patients with a seizure disorder may be enrolled if well-controlled and on non-enzyme inducing anticonvulsants Patients must not have received enzyme-inducing anticonvulsants including phenytoin, phenobarbital, valproic acid, or carbamazepine for at least 7 days prior to study enrollment; patients receiving non-enzyme inducing anticonvulsants such as gabapentin or levetiracetam will be eligible Patients with seizure disorder may be enrolled if on non-enzyme inducing anticonvulsants and if seizures are well controlled Patients who are currently receiving enzyme inducing anticonvulsants are not eligible Patients with known seizure disorder must have seizures adequately controlled with non-enzyme inducing antiepileptic medications Participants who are currently receiving enzyme-inducing anticonvulsants Patients with seizure disorder may be enrolled if on anticonvulsants and well controlled Patients taking enzyme inducing anticonvulsants Use of enzyme-inducing anticonvulsants (EIACs); a minimum interval of 10 days between the last dose of EIAC and start of this therapy will be required for research participants who were previously receiving such medications Central nervous system function defined as:\r\n* Patients with seizure disorder may be enrolled if on non-enzyme inducing anticonvulsants and if seizures are well controlled\r\n* Nervous system disorders (Common Terminology Criteria for Adverse Events [CTCAE] version 4 [v4]) resulting from prior therapy must be =< grade 2 Patients who are currently receiving enzyme inducing anticonvulsants are not eligible No enzyme inducing anticonvulsants for >= 4 weeks prior to randomization Patients can only be on non-enzyme inducing anti-convulsants; if they are on an enzyme inducing anti-convulsant, they may be converted to a non-enzyme inducing anticonvulsants Central Nervous System: Patients without seizure disorder OR patients with well-controlled seizure disorder receiving anticonvulsants may be enrolled on this protocol; anticonvulsants must not be enzyme-inducing (inducers of CYP3A, i.e., no barbiturates, phenytoin, carbamazepine, etc.) Patients with seizure disorder may be enrolled if on anticonvulsants and well-controlled; central nervous system (CNS) toxicity < grade 2 Patients must not have received enzyme inducing anticonvulsants for at least 14 days prior to enrollment Patients with a seizure disorder are eligible if well-controlled on anticonvulsants; if on a non-enzyme inducing anticonvulsant, the irinotecan (irinotecan hydrochloride) dose will be adjusted as outline in treatment plan Patients with brain metastases are eligible provided they meet all other eligibility criteria and do not require corticosteroids or enzyme-inducing anticonvulsants and provided it is felt clinically that they will not require radiotherapy in the three (3) weeks subsequent to their participation in the study
