Experimental mitochondrial vaccine takes on advanced cancers

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Patients aged 18 to 75 years at the time of acquisition informed consent form. 2. Patients with advanced malignant solid tumors such as non-small cell lung cancer or colorectal cancer, confirmed by histology or cytology, who are unable to receive or tolerate standard treatments, or who refuse standard treatments, exhibit positive expression of target antigens in the tumor tissue. 3. The presence of at least one measurable or evaluable lesion according to RECIST v1.1 criteria. 4. Eastern Cooperative Oncology Group (ECOG) performance status score: 0-2. 5. Predicted survival time ≥3 months. 6. The main organs are functioning well and the following requirements are met within 7 days before receiving treatment: ① Hemoglobin (HGB) ≥80 g/L (no blood transfusion within 14 days); Absolute neutrophil count (ANC) \>1.5×109/L; White blood cell count ≥3.0×109/L; Platelet count (PLT) ≥80×109/L; ② Total bilirubin ≤1.5× upper limit of normal value (ULN); Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) ≤2.5×ULN; If there was liver metastasis, ALT or AST≤5×ULN; ③ Creatinine (SCr) ≤1.5×ULN or creatinine clearance (CRCI) estimated by Cockcroft-Gault formula ≥60 mL/min; ④ Prothrombin time (PT), international normalized ratio (INR) ≤1.5×ULN (unless anticoagulation with warfarin); ⑤ Cardiac function: left ventricular ejection fraction ≥50%. QTcF interval ≤450 ms. 7. Men of childbearing potential and women of childbearing age voluntarily use effective contraceptive methods (e.g., condoms, intrauterine devices, spermicides) from the time of signing the informed form until 6 months after the completion of vaccination, and contraceptive use is not allowed. Female cancer patients who have a negative pregnancy test and agree not to breastfeed during the study and for at least 18 months after receipt of the trial vaccine; 8. The washout period of previous anti-tumor therapy should be at least 4 weeks, and the washout period of molecular targeted drugs should be at least 5 half-lives. Palliative radiotherapy needs to have been completed for at least 2 weeks; Chest radiation therapy needed to have been completed for at least 3 months, and major surgery needed to have been completed with at least 4 weeks of recovery. Exclusion Criteria: 1. The patient has a history of other tumors in the past, except for the history of malignant tumors that have been cured and have not recurred within 5 years before screening, such as basal cell carcinoma of the skin, squamous cell carcinoma of the skin, superficial bladder cancer, cervical cancer in situ, and intramucosal cancer of the gastrointestinal tract, which the investigator considers to be eligible for enrollment. 2. Have any uncontrolled clinical diseases (e.g., diseases of the respiratory system, circulatory system, digestive system, nervous system, hematologic system, urogenital system, endocrine system) or psychiatric or other major medical condition that the investigator considers to interfere with the provision of informed consent, to interfere with the interpretation of the trial results, to pose a risk to the study participants, or to otherwise interfere with the achievement of the study objectives. 3. Have any active autoimmune disease or a history of autoimmune disease. Participants with asthma for which medical intervention with bronchodilators was required could not be included. 4. Allergy to the trial drug (including any excipients). Previous history of severe allergy to any drug, food or vaccination, such as anaphylactic shock, allergic laryngeal edema, allergic dyspnea, allergic purpura, thrombocytopenic purpura, local allergic necrosis reaction (Arthus reaction), etc. 5. There are contraindications to subcutaneous injection. 6. Received prior antitumor therapeutic vaccine or cellular immunotherapy. 7. Participated in other drug or device clinical trials 4 weeks before screening. 8. Study participants on systemic therapy with corticosteroids (\>10 mg/ day of prednisone or equivalent doses of other glucocorticoids) or other immunosuppressive agents within 14 days before the first dose of vaccine. Inhaled or topical steroids and adrenal hormone replacement at a therapeutic dose of prednisone of 10 mg or less per day were allowed in the absence of active autoimmune disease. 9. Before the first dose of the study drug. Any toxic effects from previous antineoplastic therapy have not recovered to NCI CTCAE grade 5.0 ≤1 (any degree of alopecia, other than grade 2 previous platinum-based treatment-related neuropathy). 10. Has active infection including tuberculosis, hepatitis B, hepatitis C or human immunodeficiency virus (HIV) infection. 11. Have a history of substance abuse or known medical, psychological, or social conditions such as alcohol or drug abuse. 12. Have received any vaccine within 30 days before receiving the study vaccine or plan to receive any vaccine other than the study vaccine during the study. 13. The presence of any other factor that was deemed by the investigator to preclude study participant entry into the trial or that study participant had any medical condition that could interfere with the assessment of the safety or efficacy of the study treatment. 14. Study participants who were unwilling or unable to comply with study requirements.
