planned major surgery during the study; or incomplete recovery from prior surgery.\n* Active central nervous system (CNS) tumors.\n* Symptomatic heart failure (New York Heart Association Class II or higher).\n* Uncontrolled hypertension (systolic blood pressure greater than 150 mmHg or diastolic blood pressure greater than 100 mmHg despite optimal medical therapy).\n* Fridericia-corrected QT interval (QTcF) greater than 470 milliseconds based on the average of triplicate screening electrocardiograms.\n* Acute coronary syndrome, acute myocardial infarction, unstable angina, percutaneous coronary intervention (PCI), or coronary artery bypass graft (CABG) surgery within 6 months before the first dose.\n* Cardiomyopathy of any etiology or clinically significant valvular heart disease.\n* Clinically significant arrhythmias requiring medical treatment (well-controlled atrial fibrillation is permitted).\n* Transient ischemic attack (TIA) or stroke within 6 months before screening.\n* Uncontrolled pleural effusion, pericardial effusion, or ascites requiring drainage at least once per month or ongoing clinical intervention.\n* Active infection requiring systemic antibacterial or antiviral therapy within 14 days before the first dose. Participants receiving stable antiviral therapy for hepatocellular carcinoma or controlled hepatitis B virus (HBV) or hepatitis C virus (HCV) infection are permitted.\n* Active or uncontrolled hepatitis B virus (HBV) or hepatitis C virus (HCV) infection. Participants with controlled HBV or HCV receiving stable antiviral therapy may be eligible.\n* Known human immunodeficiency virus (HIV) infection.\n* Receipt of systemic immunosuppressive medication within 14 days before the first dose, unless permitted by the protocol.\n* History of interstitial lung disease (ILD), pneumonitis, suspected ILD or pneumonitis that cannot be excluded by screening imaging, or severe chronic obstructive pulmonary disease (COPD).\n* History of severe hypersensitivity to monoclonal antibodies or history of anaphylaxis within 6 months before screening.\n* History of allogeneic organ transplantation or graft-versus-host disease (GvHD).\n* Receipt of a live vaccine within 4 weeks before the first dose.\n* Known substance abuse or psychiatric disorder that, in the opinion of the investigator, would interfere with study participation or protocol compliance.\n* Pregnant or breastfeeding women, or participants planning to conceive or father a child during the study and for at least 6 months after the last dose of study treatment.\n* Any medical condition, laboratory abnormality, or other clinical circumstance that, in the opinion of the investigator, would make the participant unsuitable for study participation or could interfere with the interpretation of study results.","ALL","18 Years",{"count":19,"type":20},72,"ESTIMATED","INTERVENTIONAL",[23],"PHASE1","This is a first-in-human, multicenter, open-label Phase Ia\u002FIb study evaluating the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), immunogenicity, and preliminary antitumor activity of SM2275 in patients with advanced or metastatic solid tumors who have progressed after standard therapy or for whom no standard treatment is available.\n\nPhase Ia includes dose escalation to evaluate safety, identify dose-limiting toxicities (DLTs), and determine the maximum tolerated dose (MTD) and\u002For recommended Phase II dose (RP2D).
