• •* History or presence of nephrotic syndrome (except if cured), chronic nephritis.
• •10. History of immunodeficiency, including HIV positivity or other acquired/congenital immunodeficiency diseases; history of active autoimmune disease or autoimmune diseases including but not limited to Crohn's disease, ulcerative colitis, autoimmune hepatitis/enteritis/vasculitis/nephritis, etc.; or history of organ transplantation (except corneal transplant).
• •11. Presence or history of autoimmune disease requiring treatment. Subjects with hypothyroidism on stable replacement therapy or Type 1 diabetes mellitus may be eligible.

• •13. Poorly controlled diabetes (Fasting Blood Glucose \> 10 mmol/L).
• •14. Epilepsy requiring treatment.
• •II. Tumor-Related Symptoms and Treatment:
• •Known central nervous system (CNS) involvement or carcinomatous meningitis; subjects with solid tumors who have received treatment for brain metastases and have been clinically stable for at least 28 days prior to the first dose without requiring steroids or other therapy for brain metastases may be eligible.
• •Prior chemotherapy, targeted therapy, radiotherapy, or other anti-tumor therapy within 4 weeks before the first dose (calculation based on the end date of the last treatment for washout period).
