- Maximum Age: None
- Healthy Volunteers: f

Study Arms:
- Treatment (vincristine sulfate liposome) (Type: EXPERIMENTAL): Patients receive vincristine sulfate liposome via injection on days 1, 8, 15, and 22. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Based on this trial design, predict the completion outcome and termination type (if applicable).

Answer: outcome: terminate
termination_type: lack of efficacy
