Perioperative Toripalimab and Endostatin for Stage II Melanoma: A Phase II Trial

NCT ID: NCT06965231

Last Updated: 2025-05-11

Basic Information

• Recruitment Status: RECRUITING
• Clinical Phase: PHASE2
• Total Enrollment: 58 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2025-01-01
• Study Completion Date: 2029-03-30

Brief Summary

This is a Phase II clinical trial to evaluate the efficacy and safety of perioperative toripalimab (anti-PD-1) combined with recombinant human endostatin (Endostar) as postoperative adjuvant therapy in patients with clinical stage II cutaneous or acral malignant melanoma. The study aims to answer:

1. Does this combination improve the 2-year recurrence-free survival (2y-RFS) compared to historical data?

2. Is the treatment safe and tolerable for patients?

Participants will:

1. Receive 2 cycles of toripalimab before surgery (neoadjuvant therapy).

2. Undergo surgical removal of the tumor.

3. Post surgery, receive toripalimab every 2 weeks + Endostar (72-hour continuous infusion every 4 weeks) for up to 6 cycles (Endostar) or 11 cycles (toripalimab).

4. Be monitored for tumor recurrence, side effects, and survival for up to 2 years after treatment.

This is a single-arm, multicenter study involving 58 patients across several hospitals in China. Results will help determine if this combination could become a new standard adjuvant therapy for stage II melanoma.

4. Doppler ultrasound assessment: Left ventricular ejection fraction (LVEF) ≥50%;

8. Female patients must agree to use contraception (e.g., intrauterine device [IUD], oral contraceptives, or condoms) during the study and for 6 months after study completion. A negative serum or urine pregnancy test within 7 days before enrollment is required, and patients must be non-lactating. Male patients must agree to use contraception during the study and for 6 months after study completion;

9. Patients must voluntarily participate in the study, sign the informed consent form, and demonstrate good compliance.

Exclusion Criteria

1. History of allergic reactions to biological products;

2. Patients with prior or concurrent malignancies within 5 years (except cured basal cell carcinoma of skin or carcinoma in situ of cervix);

3. Any active autoimmune disease or history of autoimmune disorders (including but not limited to: autoimmune hepatitis, interstitial pneumonia, enteritis, vasculitis, nephritis; asthma requiring bronchodilators for medical intervention). Exceptions include: vitiligo, psoriasis, alopecia not requiring systemic therapy, well-controlled type I diabetes, or hypothyroidism with normal thyroid function on replacement therapy;
