New combo aims to stop leukemia from coming back

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Pathologically documented AML (except acute promyelocytic leukemia with the t(15;17) translocation) as defined by the World Health Organization (WHO) or International Consensus Classification criteria * Achieved complete response (CR)/complete remission with incomplete count recovery (CRi) response to first line HMA-Ven according to the European Leukemia Net (ELN) recommendations for diagnosis as determined by investigator review * Documented IDH1-R132 mutations (≥ 0.01%) detected in the bone marrow or blood. Mutation must be present at the time of AML diagnosis or after initiating HMA-Ven * Receiving first-line HMA-Ven with less than or equal to 4 cycles of HMA-Ven at the time of enrollment. Participants must discontinue venetoclax (Ven) at least 1 week (or 5 half-lives, whichever is shorter) from initiating study treatment * Candidate for standard of care azacitidine * Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2 (Karnofsky ≥ 50%) * No prior solid organ allograft * Recovery from the non-hematologic toxic effects of prior treatment to grade ≤ 1, or baseline value according to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) classification (excluding infertility or alopecia) * Aged ≥ 18 at the time of consent * Creatinine clearance ≥ 40 mL/min (calculated by the Cockcroft-Gault formula or measured by 24-hour urine collection) * Serum alanine aminotransferase (ALT) ≤ 3 × upper limit of normal (ULN) * Serum aspartate aminotransferase (AST) ≤ 3 × ULN * Bilirubin ≤ 2 x ULN unless due to Gilbert's syndrome or controlled autoimmune hemolytic anemia (not requiring immunosuppressive other than ≤ 20 mg of prednisolone daily) * Note: Patients with Gilbert's syndrome may be included if total bilirubin is ≤ 3 × ULN and direct bilirubin is ≤ 2 × ULN * Prothrombin time (PT) or international normalized ratio (INR)/activated partial thromboplastin time (aPTT) ≤ 1.5 × ULN * Women of child-bearing potential, men, and their respective partners, must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 90 days after the last dose of olutasidenib * Must sign and date the informed consent form prior to undergoing any study procedures Exclusion Criteria: * Prior IDH1 inhibitor (IDH1i) targeted therapy * Prior AML therapy except for HMA-Ven * History of a different malignancy unless they have been disease-free for at least 12 months and are deemed by the investigator to be at low risk for recurrence of that malignancy. Individuals with a history of other malignancies within 12 months and without any evidence of disease progression or requiring therapy may be considered, but only after consideration and approval by the Overall Principal Investigator (PI). Individuals with the following cancers are eligible if diagnosed and/or treated within the past 12 months: cervical cancer in situ, breast ductal carcinoma in situ (DCIS), and basal cell or squamous cell carcinoma of the skin * Patients with symptomatic central nervous system (CNS) metastases or other tumor location (such as spinal cord compression, other compressive mass, uncontrolled painful lesion, bone fracture, etc.) necessitating an urgent therapeutic intervention, palliative care, surgery or radiation therapy * Patients with previous allogeneic hematopoietic stem cell transplantation (HSCT) for non-AML indications, if they meet any of the following criteria: \< 100 days from time of HSCT; active acute or chronic graft versus (vs.) host disease (GvHD); or receiving immunosuppressive therapy as treatment or prophylaxis against GvHD * Note: Doses \< 20 mg methylprednisolone (or its equivalent) daily are not an exclusion criterion * Treatment with radiation therapy or major surgery (requiring general anesthesia) within 2 weeks prior to study drug dosing * Patients unable to swallow oral medications, or patients with gastrointestinal conditions (e.g., malabsorption, resection, etc.) deemed by the Investigator to jeopardize intestinal absorption * Congestive heart failure (New York Heart Association Class III or IV) or unstable angina pectoris; previous history of myocardial infarction within one year prior to study entry, uncontrolled hypertension, or uncontrolled arrhythmias * Patients with a baseline corrected QT interval by Fridericia's formula (QTcF) of \> 480 msec * Note: This criterion does not apply to patients with a bundle branch block (BBB); for participants with BBB, a cardiology consult is recommended to ensure that QTcF is not prolonged * Concomitant medication(s) known to cause Torsades de Pointes (TdP) initiated less than the duration required to reach steady-state plasma concentration (approximately five half-lives) before first dose of study drug. Medications used as needed (PRN), e.g. Zofran, and common AML supportive care drugs (e.g. levofloxacin, azoles, etc.) are exempt * Concurrent treatment with chronic corticosteroids except if chronic treatment with \< 20 mg of methylprednisolone daily or equivalent (pulse steroids for treatment or prophylaxis are allowed \[e.g., for transfusion or medication reactions\]) * Known history of seropositivity for HIV infection * Active, uncontrolled bacterial, viral, or fungal infections, requiring systemic therapy (prophylactic systemic antimicrobials permitted) * Uncontrolled disease-related metabolic disorder (e.g., hypercalcemia) * Pregnant, breastfeeding, or planning to become pregnant while enrolled in this trial or within 90 days after the last dose of olutasidenib. Pregnant or breastfeeding * NOTE: Breast milk cannot be stored for future use while the mother is being treated on study) * Plans to donate sperm or conceive a child through intercourse while enrolled in this trial or within 90 days after the last dose of olutasidenib * Unwillingness or inability to comply with procedures either required in this protocol or considered standard of care * Medical, uncontrolled disease-related metabolic disorder, psychiatric, cognitive, or other conditions that may, in the opinion of the investigator, compromise the patient's ability to understand the patient information, give informed consent, comply with the study protocol, or complete the study
