Patient description: The patient is a 41-year-old obese woman coming to the emergency room with abdominal pain and vomiting. The pain that started gradually yesterday is located in the epigastric and periumbilical regions, radiating to her back. She drinks alcohol frequently and does not smoke. She has no history of allergies and uses only multivitamins daily. Her family history is positive for hypertension (her mother). She lives with her husband and has 3 children. The abdomen is tender and soft. Her bowel sounds are normal. Her heart rate is 115/min and blood pressure 110/75 mmHg. The lab studies are remarkable for leukocytosis (19.5), urea of 8.5, high CRP (145), high amylase (1200) and Glucose level of 15. Her abdominal CT scan revealed acute edematous interstitial pancreatitis with enlarged common bile duct and intrahepatic duct confirming gall stone pancreatitis. Her pregnancy test is negative and she is not breastfeeding.

Subjects with diseases without known effective options are also eligible. a) Subjects with relapsed and/or refractory lymphoma must have had at least 2 prior lines of systemic therapy and are not candidates for high dose therapy/autologous stem cell transplant Subjects must have evaluable disease for the dose escalation, and measurable disease for the dose expansion Subjects must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1 Subjects must have a life expectancy >= 12 weeks Absolute neutrophil count >= 1,500/mcL Hemoglobin >= 9 g/dL Platelets >= 100,000/mcL Total bilirubin =< 1.5 x the institutional upper limit of normal (ULN)  Subjects who have had chemotherapy or radiotherapy within 3 weeks (4 weeks for immunotherapy; 6 weeks for nitrosoureas or mitomycin C) prior to starting the study agent Subjects with active brain metastases Subjects may not be receiving any other investigational agents or have participated in any other clinical trial involving another investigational agent for treatment of advanced solid tumors or lymphoma within 3 weeks prior to cycle 1, day 1 of the study Subjects who had major surgery or radiation therapy within 4 weeks of the first dose of study drug, except for palliative radiotherapy to a limited field, such as for the treatment of bone pain or a focally painful tumor mass Subjects with a history of allergic reactions attributed to compounds of similar chemical or biologic composition to IACS-010759 Subjects receiving metformin or other agents known to increase risk of lactic acidosis Subjects who previously received IACS-010759 or oxidative phosphorylation (OXPHOS) inhibitors Subjects with uncontrolled intercurrent illness including, but not limited to ongoing or active serious bacterial, fungal or viral infection or psychiatric illness/social situations that would limit compliance with study requirements Subjects with a history of significant cardiac disease including: congestive heart failure requiring therapy; history of myocardial infarction (MI), angina pectoris, coronary artery bypass graft (CABG) within 6 months prior to starting study treatment; clinically significant cardiac arrhythmias (e.g., ventricular tachycardia), complete left bundle branch block, high-grade atrioventricular (AV) block (e.g., bifascicular block, Mobitz type II and third degree AV block); left ventricular ejection fraction (LVEF) < 50% evaluated by echocardiogram (ECHO) or multigated acquisition scan (MUGA); increased Fridericia's correction formula (QTcF) (> 450 for men and > 470 for women) Women who are breast-feeding or pregnant as evidenced by positive serum or urine pregnancy test performed within 72 hours of first dosing. (Pregnant women are excluded from this study because it is not known whether IACS-010759 has the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with IACS-010759 breastfeeding should be discontinued if the mother is treated with IACS-010759.)
