Intratumoral Macrophage Exosomes With Mechanobiological Reprogramming for Advanced Solid Tumors

Recruiting now · Phase 1

Conditions studied: Advanced Solid Tumors, Neoplasm

In brief

The goal of this phase I clinical trial is to evaluate the safety and tolerability of intratumoral injection of mechanically reprogrammed macrophage-derived exosomes (MRMEs) in adults aged 18-65 years with advanced solid tumors who have failed, are ineligible for, or are intolerant of standard therapies.

• Must have a primary lesion suitable for local injection, accessible by direct palpation or under ultrasound/CT image guidance.
• At least one measurable lesion per RECIST v1.1 criteria.
• ECOG performance status score of 0-2.
• Expected survival ≥ 3 months.
• Adequate organ function within 7 days prior to treatment:
• Neutrophil count (NEUT#) ≥ 1.5×10\^9/L; Platelets (PLT) ≥ 80×10\^9/L; Hemoglobin ≥ 8 g/dL
• AST, ALT, ALP ≤ 2.5×ULN; Total bilirubin (TBIL) ≤ 1.5×ULN; Albumin ≥ 2.8 g/dL
• Serum creatinine ≤ 1.5×ULN or CCR > 60 ml/min
• INR ≤ 1.5; APTT ≤ 1.5×ULN
• Voluntarily participates, signs informed consent, and is able to comply with study visits and procedures.

You may not qualify if…

• Contraindications to intratumoral injection: inflammation or ulceration at injection site; severe bleeding tendency; abnormal or permanent body art (e.g., tattoos) at injection site interfering with local reaction observation.
• History of other malignancies (except cured basal cell carcinoma, squamous cell carcinoma of skin, superficial bladder cancer, cervical carcinoma in situ, intramucosal gastrointestinal cancer without recurrence for 5 years).
• Active autoimmune disease or history of autoimmune disease (including but not limited to immune-related neuropathy, multiple sclerosis, autoimmune neuropathy, Guillain-Barré syndrome, myasthenia gravis, SLE, connective tissue disease, scleroderma, IBD, autoimmune hepatitis, TEN, or Stevens-Johnson syndrome); except Type 1 diabetes on stable insulin dose.
• Anti-tumor vaccine within 4 weeks before first dose; live vaccines within 4 weeks before or during the study; major surgery or severe trauma within 4 weeks before first dose.
• Prior anti-tumor treatment toxicity not recovered to ≤ CTCAE v5.0 Grade 1.
• Serious medical conditions: NYHA Class II or higher heart dysfunction, ischemic heart disease, significant arrhythmia, poorly controlled diabetes (fasting glucose ≥ 10 mmol/L), uncontrolled hypertension (SBP > 150 mmHg and/or DBP > 100 mmHg), LVEF < 50%, QTc > 450 ms (male) or > 470 ms (female).
• Active tuberculosis or uncontrolled prior TB infection.
• Hyperthyroidism or organic thyroid disease (except hypothyroidism controlled with stable thyroid hormone replacement).
• Active infection or unexplained fever within 48 hours before first dose, or systemic antibiotics within 1 week before informed consent.
• Active HBV (HBV DNA ≥ 2000 IU/ml or 10\^4 copies/ml), active HCV (HCV antibody positive and HCV RNA above detection limit), or known HIV positive or AIDS history.
• Known neurological or psychiatric disorders (e.g., epilepsy, dementia).
• Known history of drug abuse or alcohol abuse within 3 months.
• Pregnant or breastfeeding women; participants (or their partners) planning pregnancy or unwilling to use contraception from screening to 6 months after study completion.
• Receipt of any investigational drug within 4 weeks before first dose, or concurrent enrollment in another interventional clinical study.
• Any other factors judged by the investigator that may affect study completion.
