This study evaluates the effect and safety of the drug IAP0971 in patients with advanced malignant tumors. Patients with advanced solid tumors that have not responded to standard therapy, as well as those with PD-L1-positive advanced non-small cell lung cancer, can take part. It is being conducted in Phase 1/Phase 2 and is still enrolling participants.
The summary above is a plain-language rendering of the official record. The original English title is shown for reference.
Criteria are reproduced from the ClinicalTrials.gov record in the original English. Only the trial team can determine eligibility.
Inclusion Criteria:
1. Age of 18-75 years old (including cut-off value), regardless of gender.
2. Phase I only: patients with histologically confirmed advanced or metastatic malignant solid tumors who have failed to respond to standard treatment, who have no standard treatment options, who are not currently applicable to standard treatment, or who have been assessed by the investigator to benefit from this treatment.
3. Phase II only: patients with histologically confirmed locally advanced (stage IIIB or IIIC) or metastatic (stage IV) non-small cell lung cancer (NSCLC) that is not amenable to complete surgical resection and definitive concurrent chemoradiotherapy. Note: For patients with locally advanced stage (stage IIIB/IIIC) who cannot accept radical concurrent/sequential chemoradiotherapy, they need to be evaluated by relevant professional physicians and confirmed by written records.
4. Phase II only: no prior systemic antitumor therapy for locally advanced or metastatic NSCLC (except for patients who received adjuvant/neoadjuvant chemotherapy or definitive concurrent or sequential chemoradiotherapy for locally advanced disease and disease progression ≥6 months after the last treatment).
5. Phase II only: PD-L1 positive (TPS≥50%) as determined by IHC, and patients were negative for epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) by immunohistochemistry.
6. have at least one measurable lesion according to RECIST 1.1 criteria (tumor lesion located in the previous radiotherapy area or other locoregional treatment site, generally not considered a measurable lesion unless the lesion has clearly progressed or persists beyond three months of radiotherapy).
7. Eastern Cooperative Oncology Group (ECOG) performance status 0-1.
8. predicted survival time ≥3 months.
9. with adequate organ function:
① Blood system (no blood transfusion or hematopoietic stimulation therapy within 14 days) : absolute neutrophil count (ANC) ≥1.5×109/L, platelet count (PLT) ≥100×109/L, hemoglobin (HGB) ≥90 g/L; ② Liver function: total bilirubin (TBIL) ≤1.5 times the upper limit of normal value (ULN), except Gilbert's syndrome Out of; Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤3.0 times ULN, and patients with liver metastasis or liver cancer need AST and ALT≤5.0 times ULN and total bilirubin ≤3.0 times ULN;
② Renal function: serum creatinine (Cr) ≤1.5 times ULN; If creatinine \> 1.5 times ULN, creatinine clearance (Ccr) ≥50 mL/min (calculated by Cockcroft-Gault formula) was required.
③ Coagulation function: prothrombin international normalized ratio (INR) ≤1.5 times ULN, activated partial thromboplastin time (APTT) ≤1.5 times ULN, patients with liver metastasis or liver cancer need INR and APTT≤2.5 times ULN.
10. Eligible patients (men and women) of childbearing potential must consent to use a reliable method of contraception (hormonal or barrier methods or abstinence) with their partner during the trial and for at least 6 months after the last dose; Female patients of reproductive age had to have a negative blood pregnancy test within 7 days before the first use of the study drug.
11. Subjects must give informed consent for this study and voluntarily provide written informed consent before the trial.
Exclusion Criteria:
1. Phase II only: small cell lung cancer or sarcomatoid lesion confirmed by histopathology.
2. Phase II only: previous immunotherapy, including immune checkpoint inhibitors (e.g., anti-PD-1 /PD-L1 antibody, anti-CTLA-4 antibody, etc.), immune checkpoint agonists (e.g. ICOS, CD40, CD137, GITR, OX40 antibody, etc.), immune cell therapy, and any treatment targeting the mechanism of tumor immune action.
3. Phase I only: patients received anti-tumor therapy such as systemic chemotherapy, radiotherapy, biological therapy, endocrine therapy, or immunotherapy within 4 weeks before the first dose of study drug; The following drugs were excluded according to the following criteria:
① Treatment with a small-molecule tyrosine kinase inhibitor within 2 weeks before the first dose;
② Palliative local treatment for non-target lesions within 2 weeks before the first dose; Patients received non-specific immunomodulatory therapy (such as interleukin, interferon, thymosin, not including IL-11) within 2 weeks before the first dose;
③ received Chinese herbal medicine or Chinese patent medicine with anti-tumor indications within 2 weeks before the first dose.
4. received other investigational drugs or treatments within 4 weeks before the study drug.
5. received systemic glucocorticoids (prednisone \> 10 mg/ day or equivalent) or other immunosuppressive agents within 14 days before the first dose of study drug; The use of topical, ocular, intra-articular, nasal, and inhaled glucocorticoids was excluded. Short-term prophylaxis with glucocorticoids (e.g., to prevent contrast allergy).
6. the adverse effects of previous antineoplastic therapy have not recovered to CTCAE 5.0 grade ≤1 or the relevant requirements of the inclusion criteria (except for toxicities without safety risks judged by the investigators, such as alopecia, grade 2 peripheral neurotoxicity, and hypothyroidism stable with hormone replacement therapy).
7. major surgical procedures (excluding needle biopsies) within 4 weeks before the first dose of study drug, major trauma, or the need for elective surgery during the trial.
8. prior allogeneic hematopoietic stem-cell transplantation or organ transplantation.
9. clinically symptomatic parenchymal or meningeal metastases.
10. have active infection and currently require intravenous anti-infective therapy.
