• AST and ALT ≤2.5 x institutional ULN
• Adequate cardiac function defined as follows:
• Patients with known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function using the New York Heart Association Functional Classification.
• To be eligible for this trial, patients should be class 2B or better
• Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial
• No active or prior documented autoimmune or inflammatory disorders, including inflammatory bowel disease (e.g., colitis or Crohn's disease), diverticulitis (with the exception of diverticulosis), systemic lupus erythematosus, sarcoidosis syndrome, or Wegener syndrome (granulomatosis with polyangiitis, Graves' disease, rheumatoid arthritis, hypophysitis, uveitis, etc.).
• The following are exceptions to this criterion:
• * Vitiligo or alopecia
• * Hypothyroidism (e.g., following Hashimoto syndrome) stable on hormone replacement
• * Any chronic skin condition that does not require systemic therapy
• * Patients not on biologic therapy without active disease in the last 2 years may be included, but only after consultation with the study physician
• * Patients with celiac disease controlled by diet alone
• No history of allogenic organ transplantation with exception of corneal transplantation
• No history of idiopathic pulmonary fibrosis or evidence of interstitial lung disease on imaging
• No known severe concurrent illness:
• Known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.
• Active or recurrent hepatic disorders including cirrhosis, hepatitis B and C. Patients with a past or resolved HBV infection, defined as the presence of hepatitis B core antibody (anti-HBc) and absence of hepatitis B surface antigen (HBsAg) are eligible. Patients positive for hepatitis C (HCV) antibody are eligible only if polymerase chain reaction is negative for HCV RNA.
• Active tuberculosis infection (clinical evaluation that includes clinical history, physical examination and radiographic findings, and TB testing in line with local practice)
• Human Immunodeficiency Virus (positive HIV 1/2 antibodies).
• Active chronic infections requiring systemic therapy.
• History of esophageal gastric varices, severe ulcers, wounds that do not heal, abdominal fistula, intra-abdominal abscesses, or acute gastrointestinal bleeding within 6 months of enrollment
• History of any grade arterial thromboembolic event, Grade 3 and above venous thromboembolic event , as specified in National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) 6.0, transient ischemic attack, cerebrovascular accident, hypertensive crisis, or hypertensive encephalopathy within 12 months prior to enrollment
• History of perforation of the gastrointestinal tract and/or fistula, history of gastrointestinal obstruction (including incomplete intestinal obstruction requiring parenteral nutrition), extensive bowel resection (partial colectomy or extensive small bowel resection) within 6 months prior to enrollment

• Nasal bleeding /epistaxis (bloody nasal discharge is allowed)
• Current use of prophylactic or full-dose anticoagulants or anti-platelet agents for therapeutic purposes that is not stable prior to randomization is not allowed. The use of full-dose anticoagulants is permitted as long as the international normalized ratio (INR) or activated partial thromboplastin time (aPTT) is within therapeutic limits according to the medical standard of the enrolling institution
