  • Has any musculoskeletal, neuromuscular, neurosensory, other neurological or related disorder that affects the participant's use of his or her foot and/or would impair his/her completion of study assessments as determined by the investigator.
  • Has any significant medical history or examination findings related to the participant's plantar nodule(s), which in the investigator's opinion, would make the participant unsuitable for study intervention administration or required assessments and evaluations.

  • Has a clinically significant laboratory abnormality.
  • Has concurrent diseases that might interfere with the conduct of the study, confound the interpretation of the study results or endanger the participant's well-being, or any significant hematological, endocrine, cardiovascular, respiratory, renal, hepatic, or gastrointestinal disease. If there is a history of such disease but the condition has been stable for greater than 1 year and is judged by the investigator not to interfere with participation in the study, the participant may be included, with the documented approval of the medical monitor.
