A Phase I Study to Investigate the Safety, Tolerability and PK of HLX60 (Anti-GARP Monoclonal Antibody) in Subjects With Solid Tumors or Lymphoma

Exclusion Criteria

• •1. Have had other malignant tumors within 3 years before enrollment, except: (a) those with cured cervical carcinoma in situ or non-melanoma skin cancer; (b) those with cured second primary cancer without recurrence within 3 years; (c) those with double primary cancers believed to be able to benefit from this study; (d) those whose metastasis has been clearly excluded from a certain primary tumor source;
• •2. A history of (non-infectious) interstitial lung disease (ILD) requiring steroid use, current ILD, or a suspicion of ILD cannot be ruled out by imaging at screening; Note: Patients with radiation pneumonitis judged to be mild by the investigator can be enrolled.
• •3. The adverse reactions (except alopecia and other adverse reactions determined by the investigator to have no safety risk) of previous anti-tumor therapy have not yet recovered to ≤ grade 1 (CTCAE V5.0);
• •4. Those who are known to have severe anaphylaxis (grade 4 or greater in CTCAE V5.0) to macromolecular protein preparations/monoclonal antibodies or to any component of the investigational product;
• •5. Patients with any of the following unstable or poorly controlled diseases:1)Active systemic infectious diseases requiring intravenous antibiotics within 2 weeks before the first administration of the investigational product;2)Any poorly-controlled cardiovascular and cerebrovascular clinical symptoms or diseases, including but not limited (1) NYHA Class II or greater cardiac failure or left ventricular ejection fraction (LVEF) \<50%;（2）unstable angina pectoris； (3) myocardial infarction and cerebral infarction within 6 months, (4) clinically significant supraventricular or ventricular arrhythmia without clinical intervention or poorly controlled after clinical intervention;3)Other chronic diseases which, in the opinion of the investigator, may compromise the safety of the patient or the integrity of the study;
• •6. Assessed as unsuitable for inclusion by the investigator, due to brain metastases, spinal cord compression, or cancerous meningitis with clinical symptoms, or uncontrolled brain or spinal cord metastases that have been evidenced; Note: Patients with asymptomatic or stable brain metastases, spinal cord compression, or carcinomatous meningitis as judged by the investigator were eligible for enrollment.
• •7. Those who have received anti-GARP or anti-GARP/TGF-β antibody therapy;
• •8. Have active autoimmune diseases (including but not limited to the following diseases or syndromes, such as interstitial pneumonia, colitis, hepatitis, hypophysitis, vasculitis, nephritis, hyperthyroidism, and hypothyroidism), except: vitiligo or cured childhood asthma/allergy that does not need any intervention in adulthood, autoimmune mediated hypothyroidism treated with stable dose of thyroid replacement hormone, and type I diabetes treated with stable dose of insulin; those in a stable condition and requiring no systemic immunosuppressant therapy (including corticosteroid hormone) are allowed to be enrolled;
• •9. Have received systemic corticosteroids (prednisone \> 10 mg/d or equivalent dose of similar drug) or other immunosuppressants within 14 days before the first administration; Except: patients treated with topical, ocular, intra-articular, intranasal, and inhaled corticosteroids; those with short term use of corticosteroids for prophylaxis, such as contrast agents;
• •10. Patients in pregnancy \[confirmed by serum beta-human chorionic gonadotropin (ß-HCG) test\] or breastfeeding;
• •11. With a history of immunodeficiency, including human immunodeficiency virus (HIV)-positive or other acquired or congenital immunodeficiencies, or a history of organ transplantation;
• •12. Have active tuberculosis。
• •13. Active HBV, HCV infection or co-infection;
• •14. Have received live vaccines within 28 days prior to the first administration;
• •15. Patients whose medical history or any other evidence suggests that participation in the study may confuse the results, or subjects for whom the investigator believes the study is not in their best interest.
