About

Evaluate the efficacy and safety of SH009 injection therapy for patients with advanced solid tumors

Full description

Based on the obtained data from the dose escalation phase of the Phase I clinical trial, select safe and effective tumor indications (including but not limited to gastric cancer, liver cancer, head and neck tumors, breast cancer, non-small cell lung cancer, esophageal cancer, etc.) and dose levels for dose expansion studies. Further evaluate efficacy, safety, and pharmacokinetics to provide a basis for determining the recommended dose for Phase II clinical trials.

(6) Life expectancy ≥12 weeks;
(7) Bone marrow function meets the following criteria: neutrophil count ≥ 1.5 × 10^9/L; platelet count ≥ 90 × 10^9/L (platelet count ≥ 75 × 10^9/L in patients with liver cancer); hemoglobin (Hb) ≥ 90 g/L;
(8) Liver function meets the following criteria: total bilirubin(TBIL) ≤ 1.5 × ULN (total bilirubin ≤ 3 × ULN for subjects with Gilbert's syndrome); aspartate aminotransferase (AST) and alanine and aminotransferase (ALT) ≤ 3 × ULN (ALT and AST ≤ 5 × ULN for subjects with liver cancer or liver metastases);
(9) Renal function meets the following criteria: serum creatinine clearance(CLcr) ≥ 50 mL/min (calculated according to Cockcroft-Gault formula); urine dipstick test results show that urine protein < 2 +, urine protein ≥ 2 + subjects should undergo 24-hour urine collection and urine protein content < 1g within 24 hours;
(10) Coagulation function meets the following criteria: prothrombin time (PT), activated partial thromboplastin time (APTT) and international normalized ratio (INR) ≤ 1.5× ULN;
(11) Female subjects of childbearing potential must use effective contraception during the trial and for 6 months after the last dose, and have a negative pregnancy test within 7 days before treatment initiation (except those who are surgically sterilized or postmenopausal). Male subjects must agree to use effective contraception during the trial and for 6 months after the last dose;
(12) The subject is fully informed about this trial before its commencement and voluntarily signs and dates the informed consent form.

Exclusion criteria

(1) Prior exposure to any CD47 antibody, SIRPα antibody, or CD47/SIRPα recombinant protein;
(2) Prior treatment with adoptive cellular therapies such as CAR-T, TCR-T, or TIL. Prior administration of an anti-cancer vaccine, or use of live or live-attenuated vaccines within 4 weeks prior to the first dose;
(3) Systemic anti-tumor therapies within the specified timeframes prior to the first dose of study drug: Chemotherapy, antibody-based targeted therapy, endocrine therapy, or immunotherapy within 3 weeks. Mitomycin or nitrosoureas within 6 weeks. Oral fluoropyrimidines (e.g., S-1, capecitabine) and small molecule targeted agents within 2 weeks or 5 half-lives of the drug (whichever is longer).Chinese/herbal medicines with anti-cancer activity indicated in their labeling must be discontinued prior to enrollment. Prior radical radiotherapy within 3 months before study drug administration is excluded. Palliative radiotherapy administered within 2 weeks prior to dosing is allowed if the dose meets local palliative care standards and the radiation field covers less than 30% of the bone marrow area;
(4) Received any investigational drug within 28 days before administration of this trial, or participated in another clinical study at the same time, except for the following circumstances: the patient participated in an observational, non-interventional clinical study, or was in the follow-up period after the end of treatment in an interventional clinical study but the drug withdrawal had exceeded the washout period;
(5) Had major organ surgery (excluding puncture biopsy) or had significant trauma within 4 weeks before the first administration, or needed to undergo elective surgery during the trial period;
(6) Patients who received systemic glucocorticoids (dexamethasone > 10 mg/ day or equivalent dose of the same drug) or other immunosuppressive therapy within 14 days before the first administration; except for topical, ocular, intra-articular, intranasal, and inhaled glucocorticoids; short-term use of glucocorticoids for prophylactic treatment (e.g., prevention of contrast allergy);
(7) Symptomatic brain parenchymal or leptomeningeal metastases, deemed by the investigator as unsuitable for enrollment;
(8) Prior immunotherapy with ≥Grade 3 irAE or ≥Grade 2 immune-related myocarditis;
(9) Severe or uncontrolled systemic disease, including but not limited to: uncontrolled pleural or peritoneal effusion; uncontrolled diabetes; ventricular arrhythmia requiring intervention; acute coronary syndrome, congestive heart failure, stroke, or other ≥Grade 3 cardiovascular event within 6 months; NYHA Class ≥II or LVEF <50%; clinically significant QTcF prolongation or arrhythmia risk (baseline QTcF >450 msec for males or >470 msec for females); clinically uncontrolled hypertension (SBP >160 mmHg and/or DBP >90 mmHg after treatment) as judged by the investigator. Subjects judged by the investigator as unsuitable due to any such condition;
(10) History of pneumonia requiring hormone therapy or interstitial lung disease (including past and current history); active pulmonary infection;
(11) Active infection requiring intravenous anti-infective therapy within 1 week prior to study drug administration (fever attributed to the tumor per investigator's judgment is acceptable). History of self-limited infections that have resolved is acceptable;
(12) Active Hepatitis B, Hepatitis C, or syphilis infection. Subjects positive for HBeAb or HBsAg are eligible if HBV-DNA ≤200 IU/mL. Subjects positive for HCV-Ab are eligible if HCV-RNA ≤ the upper limit of normal at the research center. Subjects with hepatocellular carcinoma and HBV-DNA ≥2000 IU/mL must receive antiviral/hepatoprotective therapy first and can only enroll after HBV-DNA decreases to <2000 IU/mL;
(13) History of primary immunodeficiency, including positive human immunodeficiency virus (HIV) test, or suffering from other acquired, congenital immunodeficiency diseases;
(14) History of other malignancies within 5 years prior to the first dose, except for:

a) Any other invasive malignancy, treated with curative intent, with a disease-free interval >3 years and deemed by the investigator not to affect efficacy evaluation for the current tumor. b) Adequately treated basal cell or squamous cell skin cancer, superficial bladder cancer, carcinoma in situ of the cervix or breast, or other locally cured cancers;
(15) History or presence of autoimmune disease within 2 years, including but not limited to systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel disease, autoimmune thyroid disease, multiple sclerosis, vasculitis, glomerulonephritis or high risk (e.g., post-transplant immunosuppression). Exceptions: stable type 1 diabetes on fixed-dose insulin; autoimmune hypothyroidism on hormone replacement only; skin conditions not requiring systemic treatment (e.g., eczema, rash covering<10% BSA, psoriasis without ocular symptoms);
(16) Arterial thromboembolic events within 6 months prior to the first dose, including myocardial infarction, unstable angina, cerebrovascular accident, or transient ischemic attack. History of deep vein thrombosis, pulmonary embolism, or other serious thromboembolism within 3 months prior to the first dose (catheter-related or superficial venous thrombosis is not considered "serious").

(17) Subjects who had receive allogeneic hematopoietic stem cell transplantation or solid organ transplantation (except corneal transplant);
(18) According to CTCAE 5.0, adverse reactions from previous anti-tumor therapy have not yet returned to ≤ grade 1 (except for toxicities which are judged by researchers to be safe, such as hair loss, pigmentation, hypothyroidism stabilized by hormone replacement therapy and peripheral neuropathy (need to recover to ≤ grade 2)). Irreversible toxicity (e.g., hearing loss) that is not reasonably expected to be aggravated by the study drug may be allowed after consultation with the medical monitor;
(19) Known history of severe hypersensitivity to macromolecular protein preparations/monoclonal antibodies(CTCAE v5.0 Grade ≥3), or any component of the study drug;
(20) Known alcohol and/or drug dependence, or any other condition deemed by the investigator to affect the safety or compliance of the study treatment, including but not limited to psychiatric disorders;
