• The effects of golidocitinib on the developing human fetus are unknown. For this reason and because JAK1 inhibitor agents as well as other therapeutic agents used in this trial are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. (Refer to Pregnancy Assessment Policy MD Anderson Institutional Policy # CLN1114). This includes all female patients, between the onset of menses (as early as 8 years of age) and 55 years unless the patient presents with an applicable exclusionary factor which may be one of the following: * Postmenopausal (no menses in greater than or equal to 12 consecutive months) * History of hysterectomy or bilateral salpingo-oophorectomy * Ovarian failure (follicle stimulating hormone and estradiol in menopausal range, who have received whole pelvic radiation therapy) * History of bilateral tubal ligation or another surgical sterilization procedure
• Approved methods of birth control are as follows: Hormonal contraception (i.e. birth control pills, injection, implant, transdermal patch, vaginal ring), intrauterine device (IUD), tubal ligation or hysterectomy, subject/partner post vasectomy, implantable or injectable contraceptives, and condoms plus spermicide. Not engaging in sexual activity for the total duration of the trial and the drug washout period is an acceptable practice; however periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of birth control. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately
• Women treated or enrolled on this protocol must agree to use adequate contraception prior to the study, for the duration of study participation, and 4 months after completion of golidocitinib administration. If female patients wish to mother children, they should be advised to arrange for freezing of eggs prior to the start of study treatment
• Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 4 months after completion of golidocitinib administration. Men must refrain from donating sperm during their participation in the study and at least for 6 months after the last treatment. If male patients wish to father children, they should be advised to arrange for freezing of sperm samples prior to the start of study treatment

• Any of the following cardiac criteria: * Congestive heart failure (CHF) per New York Heart Association (NYHA) classification > class II * Clinically significant valvular diseases, hypertrophic or constrictive cardiomyopathy * Any clinically significant abnormalities in rhythm, conduction or morphology of resting electrocardiogram (ECG), e.g., complete left bundle branch block, third degree heart block, and second-degree heart block, PR interval > 250 msec * Cardiac ventricular arrhythmias requiring anti-arrhythmic therapy * Acute myocardial infarction (AMI) within 6 months prior to starting treatment, unstable angina or new-onset angina * Patients with heart transplant * Mean resting corrected Fridericia's correction formula (QTcF) interval (referred in the protocol as corrected QT interval [QTC]) > 450 ms on screening electrocardiogram (ECG) * Patients with factors that increase the risk of QT prolongation or arrhythmic events (e.g., congenital long QT syndrome, any concomitant medication known to prolong the QT interval) or family history of long QT interval syndrome or unexplained sudden death under 40 years of age in first degree relatives) * Patients with acute thrombotic diseases such as pulmonary embolism (PE) and deep venous thrombosis (DVT) within 90 days. Patients with remote history (> 6 months) of provoked PE or DVT (e.g., line-associated DVT; DVT or PE after surgical procedure), and patients on appropriate anticoagulation for 90 or more days from the event will not be excluded
• Another malignancy within 5 years prior to enrollment with the exception of adequately treated in-situ carcinoma of the cervix, uterus, basal or squamous cell carcinoma or non-melanomatous skin cancer
• Refractory nausea and vomiting if not controlled by supportive therapy, chronic gastrointestinal diseases, inability to swallow the formulated product or previous significant bowel resection that would preclude adequate absorption of golidocitinib
• History of hypersensitivity to active or inactive excipients of golidocitinib or drugs with a similar chemical structure or class
• As judged by the investigator, any evidence of severe or uncontrolled systemic diseases, including uncontrolled hypertension or active bleeding diatheses. Screening for chronic conditions is not required
• Concurrent conditions that in the investigator’s opinion would jeopardize compliance with the protocol
• Psychological, familial, sociological, or geographical conditions that do not permit compliance with the protocol
• All patients must avoid concomitant use of medications, herbal supplements and/or ingestions of foods with known potent inducer/inhibitory effects on CYP3A activity whenever feasible. Such drugs must have been discontinued for an appropriate period before they enter screening and for a period after the last dose of golidocitinib
• Patients with psychiatric illness/social situations that would limit compliance with study requirements
• Pregnant women are excluded from this study because golidocitinib is a JAK1 inhibitor agent with 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 golidocitinib, breastfeeding should be discontinued if the mother is treated with golidocitinib. These potential risks may also apply to other agents used in this study
