These patients will not be evaluable for hematologic toxicity * Creatinine clearance or radioisotope glomerular filtration rate (GFR) \>= 70 ml/min/1.73 m\^2 (within 7 days prior to enrollment), or * A serum creatinine based on age/gender (within 7 days prior to enrollment) * Age 1 to \< 2 years, maximum serum creatinine (mg/dL) male 0.6, female 0.6 * Age 2 to \< 6 years, maximum serum creatinine (mg/dL) male 0.8, female 0.8 * Age 6 to \< 10 years, maximum serum creatinine (mg/dL) male 1, female 1 * Age 10 to \< 13 years, maximum serum creatinine (mg/dL) male 1.2, female 1.2 * Age 13 to \< 16 years, maximum serum creatinine (mg/dL) male 1.5, female 1.4 * Age \>= 16 years, maximum serum creatinine (mg/dL) male 1.7, female 1.4 * Bilirubin (sum of conjugated + unconjugated) =\< 1.5 x upper limit of normal (ULN) for age (within 7 days prior to enrollment) * Serum glutamate-pyruvate transaminase (SGPT) (alanine aminotransferase \[ALT\]) =\< 135 U/L. (For the purpose of this study, the ULN for SGPT is 45 U/L) (within 7 days prior to enrollment) * Serum albumin \>= 2 g/dL (within 7 days prior to enrollment) * Corrected QT (QTc )interval =\< 450 milliseconds (within 7 days prior to enrollment) * Note: Patients should avoid concomitant medication known or suspected to prolong QTc interval or cause Torsades de Pointes. Patients who are receiving drugs that prolong the QTc are eligible if the drug is necessary and no alternatives are available * Patients with seizure disorder may be enrolled if on anticonvulsants and well controlled * Nervous system disorders (Common Terminology Criteria for Adverse Events \[CTCAE\] version \[v\]5.0) resulting from prior therapy must be =\< grade 2, with the exception of decreased tendon reflex (DTR). Any grade of DTR is eligible * All patients and/or their parents or legally authorized representatives must sign a written informed consent. Assent, when appropriate, will be obtained according to institutional guidelines Exclusion Criteria: * Pregnant or breast-feeding women will not be entered on this study due to risks because there is yet no available information regarding human fetal or teratogenic toxicities. Pregnancy tests must be obtained in girls who are post-menarchal. Males or females of reproductive potential may not participate unless they have agreed to use an effective non-hormonal contraceptive method for the duration of study treatment and for at least 1 month after last dose of AG-120 (ivosidenib). Since AG-120 (ivosidenib) may decrease concentrations of hormonal contraceptives, hormonal contraceptives are not considered effective contraception when co-administered with AG-120 (ivosidenib) * Patients receiving corticosteroids who have not been on a stable or decreasing dose of corticosteroid for at least 7 days prior to enrollment are not eligible. If used to modify immune adverse events related to prior therapy, \>= 14 days must have elapsed since last dose of corticosteroid * Patients who are currently receiving another investigational drug are not eligible * Patients who are currently receiving other anti-cancer agents are not eligible * Patients who are receiving cyclosporine, tacrolimus or other agents to prevent graft-versus-host disease post bone marrow transplant are not eligible for this trial * Patients who are currently receiving drugs that are strong inducers or moderate to strong inhibitors of CYP3A4 are not eligible. Strong inducers or moderate to strong inhibitors of CYP3A4 should be avoided from 14 days prior to enrollment to the end of the study. Note: CYP3A4 inducing anti-epileptic drugs and dexamethasone for CNS tumors or metastases, on a stable dose, are allowed. In addition, patients receiving sensitive or narrow therapeutic range substrates of CYP3A4 are not eligible * Patients with a history of progressive multifocal leukoencephalopathy are not eligible * Patients who have an uncontrolled infection are not eligible * Patients who have received a prior solid organ transplantation are not eligible * Patients who in the opinion of the investigator may not be able to comply with the safety monitoring requirements of the study are not eligible
