Study Arms:
- Single arm study (Type: EXPERIMENTAL): ReposMBZ 100 mg capsule by mouth followed by 8h PK sampling to decide the initial daily dose.~Treatment: Repos MBZ capsules by mouth twice daily for 16 weeks, daily dose 50mg-4g, based on the serum level of mebendazole.

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

Answer: outcome: terminate
termination_type: lack of efficacy
