ClinConnect Summary

This clinical trial is studying a new treatment called Paclitaxel Cationic Liposomes for patients with advanced solid tumors, which are types of cancer that form solid masses in the body. The trial is in its early stages (Phase 1), focusing on understanding how safe and effective this new treatment might be. It is currently open for participants aged 18 and older who have specific types of advanced solid tumors, including cancers of the gastrointestinal tract, gynecological cancers, and non-small cell lung cancer. To join, participants must have measurable tumors and a life expectancy of at least three months, among other health criteria.

If eligible, participants will receive the study drug and will be monitored closely for any side effects and how well the treatment works. It's important to know that prior treatments or certain health conditions might prevent some individuals from joining. All participants will need to understand the study fully and provide their written consent before starting. This trial is a chance to contribute to cancer research and potentially access a new treatment option.

Eligibility criteria

• Inclusion Criteria:
• • 1. Age ≥ 18 years.
• * 2. Histologically or cytologically diagnosed advanced solid tumors suitable for arterial infusion chemotherapy, including but not limited to the following types:
• • Gastrointestinal tumors (e.g., gastric cancer, liver cancer, cholangiocarcinoma, pancreatic cancer, colorectal cancer, etc.);
• • Gynecological tumors (e.g., ovarian cancer, endometrial cancer, etc.);
• • Non-small cell lung cancer (NSCLC);
• • Liver metastases.
• • 3. According to RECIST 1.1, at least one measurable lesion in the arterial infusion area.
• • 4. If life-threatening primary lesions are within the arterial infusion area, limited lesions outside the arterial infusion area at baseline are acceptable.
• • 5. Eastern Cooperative Oncology Group (ECOG) performance status score of 0-2.
• • 6. Life expectancy of at least 3 months.
• * 7. Adequate organ function, with laboratory tests meeting the following criteria (no blood transfusion or hematopoietic growth factors within 14 days):
• • Absolute neutrophil count (ANC) ≥ 1.5 × 10\^2/L.
• • Platelets (PLT) ≥ 100 × 10\^9/L.
• • Hemoglobin (Hb) ≥ 90 g/L.
• • Total bilirubin (TBIL) ≤ 1.5 × upper limit of normal (ULN); for individuals with liver metastasis or liver cancer, TBIL ≤ 2 × ULN.
• • Alanine aminotransferase (ALT), aspartate aminotransferase (AST) ≤ 2.5 × ULN; for liver metastasis or liver cancer, ALT, AST ≤ 5 × ULN.
• • Creatinine clearance (Ccr) \> 50 mL/min (calculated using the Cockcroft-Gault formula).
• • Activated partial thromboplastin time (APTT) ≤ 1.5 × ULN; international normalized ratio (INR) ≤ 1.5 × ULN.
• • 8. Fertile individuals (male and female) must agree to use reliable contraceptive methods (hormonal contraceptives, barrier methods, or abstinence) with their partners during the trial and for at least 6 months after the last dose of study medication. Women of childbearing potential must have a negative pregnancy test within 7 days prior to enrollment.
• • 9. Fully understand the clinical trial and voluntarily sign a written informed consent form.
• Exclusion Criteria:
• • 1. Received chemotherapy, radiotherapy, biological therapy, endocrine therapy, targeted therapy, immunotherapy, or participated in another clinical trial within 4 weeks prior to the first administration of the study drug, or within 4 weeks or 5 half-lives of the treatment drug (whichever is shorter).
• • 2. Known symptomatic central nervous system or meningeal metastases, or other evidence of uncontrolled central nervous system or meningeal metastases, deemed unsuitable for enrollment by the investigator.
• • 3. Unresolved adverse reactions from previous anti-tumor treatments not yet recovered to CTCAE 5.0 grade ≤ 1 (except for alopecia or other toxicities deemed non-risky by the investigator).
• • 4. Concurrent participation in another clinical trial, unless it is observational (non-interventional) or in the follow-up period of an interventional trial.
• • 5. Major surgery or invasive intervention within 28 days prior to the first dose.
• • 6. Use of any anti-cancer herbal or traditional Chinese medicine approved by the National Medical Products Administration (NMPA) within 14 days prior to the first dose.
• • 7. Known severe allergic reactions to the study drug or its components/excipients.
• • 8. Active bacterial, fungal, or viral infections requiring intravenous antibiotic, antifungal, or antiviral treatment prior to the first dose. Participants receiving prophylactic infection treatment with no signs of active infection may be considered for enrollment.
• • 9. History of immunodeficiency diseases, including positive HIV antibodies.
• • 10. Hepatitis B surface antigen (HBsAg) positive with HBV DNA above the measurable limit or 1000 copies/mL (500 IU/mL) (whichever is lower), or HCV antibody positive with HCV RNA above the measurable limit or 1000 copies/mL (whichever is lower). Individuals whose levels are reduced to below the standard following antiviral treatment may be screened.
• • 11. Underlying medical conditions (including laboratory abnormalities), alcohol or drug abuse, or dependence that may impair the administration of study drugs or interpretation of drug toxicity and adverse events (AEs), or lead to insufficient or reduced trial compliance.
• * 12. Severe cardiovascular disease history, including but not limited to:
• • Severe cardiac rhythm or conduction abnormalities requiring clinical intervention, such as ventricular arrhythmias or grade II-III atrioventricular block;
• • Average QTcF \> 450 ms from three resting 12-lead ECGs;
• • Acute coronary syndrome, congestive heart failure, stroke, or other grade 3 or higher cardiovascular events within 6 months prior to the first dose;
• • New York Heart Association (NYHA) class II or higher, or left ventricular ejection fraction (LVEF) \< 50%;
• • Any factors increasing the risk of QTc prolongation or arrhythmias, such as heart failure, hypokalemia, congenital long QT syndrome, family history of long QT syndrome or unexplained sudden death in a first-degree relative under 40 years old, or concurrent use of QT-prolonging drugs.
• • Uncontrolled hypertension (screening systolic BP ≥ 160 mmHg and/or diastolic BP ≥ 100 mmHg).
• • 13.History of other malignancies within the past 3 years or concurrent active malignancies (localized, curable malignancies such as basal cell carcinoma of the skin, squamous cell carcinoma of the skin, superficial bladder cancer, in situ prostate cancer, cervical carcinoma in situ, and in situ breast cancer may be included).
• • 14. Patients with ultrasound-detected limb vascular thrombosis with potentially serious consequences during screening, or participants with thromboembolic events within 3 months prior to enrollment.
• • 15. Individuals with coagulopathy or a history of severe bleeding, or who experienced major bleeding events such as intracranial hemorrhage, gastrointestinal bleeding, or purpura within the last 3 months.
• • 16. Pregnant or breastfeeding women.
• • 17. Any other reasons deemed by the investigator to make the individual unsuitable for participation in the clinical trial.
