What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.

This trial targets 120 participants in total. It began in 2023-09-21 with a primary completion date of 2026-09.

Brief Summary

This is a Phase I Clinical Trial to Evaluate the Tolerability, Safety, Pharmacokinetics and Preliminary Antitumor Activity of PE0116 and PE0105 Injection in Treatment of Patients with Advanced Solid Tumor.

Eligibility Criteria

Inclusion Criteria: 1. Patients who voluntarily sign the informed consent form, understand the study and are willing to follow and able to complete all study procedures; 2. Male or female, 75 ≥ age ≥ 18 years; 3. Patients who have histologically or cytologically confirmed metastatic or unresectable locally advanced, recurrent solid tumors that are refractory to or intolerable with standard treatment, or for which no standard effective treatment is available; 4.

Patients who have at least one evaluable lesion in Phase Ia study, and have measurable lesions in Phase Ib (according to RECIST v1.1). Tumor lesions in the area of prior radiotherapy (or other local therapy) with unequivocal progression after radiotherapy as confirmed by imaging can be considered as measurable lesions; 7. Patients who are ≥ 4 weeks after receiving anti-tumor therapy, such as chemotherapy, radiotherapy, biotherapy, endocrine therapy and immunotherapy, before the first dose of study drug, with the following exceptions: 1. ≥ 6 weeks after receiving nitrosourea or mitomycin C before the first dose of study drug; 2. ≥ 2 weeks or 5 half-life periods (whichever is longer) of oral fluorouracils and small molecule targeted agents before the first dose of study drug; 3. ≥ 2 weeks after receiving traditional Chinese medicine with anti-tumor indications before the first dose of study drug； 8. Patients who have suitable organ and hematopoietic function without severe heart, lung, liver, renal dysfunction and immunodeficiency according to the following laboratory tests: 1. Absolute neutrophil count (ANC) ≥ 1.5 × 10\^9/L; 2. Absolute white blood cell count (WBC) ≥ 3.0 × 10\^9/L; 3. Platelets ≥ 75 x 10\^9/L; 4. Hemoglobin ≥ 90 g/L; 5. Serum creatinine ≤ 1.5 times the upper limit of normal (ULN); 6. AST and ALT ≤ 2.5 × ULN, or ≤ 5 × ULN for patients with liver cancer or metastases to liver; 7. Serum total bilirubin (TBIL) ≤ 1.5 × ULN; 8. International normalized ratio (INR) ≤ 1.5 × ULN and activated partial thromboplastin time (APPT) ≤ 1.5 × ULN (except for patients receiving anticoagulant therapy); 9. Myocardial enzyme CK and CKMB test values are within the normal range, or mildly abnormal but judged by the investigator to be suitable for enrollment; 10. Thyroid function (FT3, FT4, and TSH) test values are within the normal range, or mildly abnormal but judged by the investigator to be suitable for enrollment. 9. Male subjects and female subjects of childbearing potential should agree to use effective contraception from the signing of the informed consent form until 3 months after the last dose. Exclusion Criteria: 1. Subjects who have central nervous system metastasis with clinical symptoms (e.g., brain edema, hormone intervention required, or progression of brain metastasis) and/or carcinomatous meningitis. However, subjects who have received prior treatment for brain or meningeal metastases can be included if they have remained stable clinically for at least 2 months and systemic hormone therapy (prednisone at a dose of \> 10 mg/day or other hormone at an equivalent dose) has been discontinued for more than 4 weeks; 2. Subjects who fail to recover from adverse reactions of prior therapies to ≤ CTCAE V5.0 Grade 1. (Patients with residual alopecia, chromatosis and peripheral neurotoxicity that has recovered to ≤ CTCAE Grade 2, and with long-term toxicity caused by radiotherapy that cannot recover as judged by the investigator may be included); 3. Subjects with systemic diseases that have not been stably controlled after treatment, such as history of severe cardiovascular and cerebrovascular diseases, diabetes mellitus, hypertension, etc.; 4. Subjects who have any active auto-immune disease or evidence of auto-immune disease, or systemic syndrome previously requiring treatment with systemic steroids or immunosuppressive drugs. (Patients with inactive vitiligo, psoriasis and post-treatment childhood asthma/atopy within 2 years, or thyroid disease that has been controlled with alternative therapy/non-immunosuppression may be included); 5. For subjects requiring systemic treatment with corticosteroids (at doses equivalent to \> 10 mg prednisone/day) or other immunosuppressive agents within 14 days prior to enrollment or during the study period, enrollment is allowed under the following situations: 1. Subjects are allowed to use topical or inhaled glucocorticoids; 2. Short-term (≤ 7 days) use of glucocorticoids for the prophylaxis or treatment of non-autoimmune allergic diseases is permitted; 6. Subjects who have a history of infection with human immunodeficiency virus, or other acquired, congenital immunodeficiency diseases, or a history of organ transplantation, or a history of stem cell transplantation; 7. Patients with tuberculosis that is active at screening; 8. Patients with active chronic hepatitis B or active hepatitis C. Patients as hepatitis B virus carriers, and with stable hepatitis B after drug treatment (DNA titers should not be higher than 1000 copies/mL), and cured hepatitis C (HCV RNA test results are required to be below the lower limit of the testing site) can be enrolled; 9. Patients who have received treatment with anti-4-1BB targeting drugs; 10. Patients with a known history of severe allergic reactions (CTCAE v5.0 ≥ Grade 3) to macromolecular protein preparations/monoclonal antibodies, or to any component of the study drug; 11. Patients who are expected to have major surgery during the study, including the 28-day screening period; 12. Patients with serious infection within 4 weeks prior to the first dose, or with active infection requiring oral or intravenous antibiotics within the first 2 weeks; 13.
