A Study to Assess Collagenase Clostridium Histolyticum (CCH) in the Treatment of Plantar Fasciitis (PFA)

Key Inclusion Criteria: * Have no significant medical history or examination findings related to the foot to be treated, which in the investigator's opinion, would make the participant unsuitable for study intervention administration. * Have a diagnosis of plantar fasciitis for ≥6 months, which has not responded to conservative therapies. Conservative therapies may include rest, physical therapy, splinting/bracing, orthotics, icing, physiotherapy, acetaminophen, corticosteroids, or nonsteroidal anti-inflammatory drugs (NSAIDs). * Have current foot pain due to plantar fasciitis. Key Exclusion Criteria: * Has any musculoskeletal, neuromuscular, neurosensory, other neurological or related disorder that affects the participant's use of his/her feet and/or would impair his/her completion of study assessments as determined by the investigator either due to the disorder or due to pain. * Has a clinically meaningful laboratory abnormality. * Has a body mass index ≥35 kilograms per meter squared (kg/m\^2). * Has a known bleeding disorder, which, in the investigator's opinion, would make the participant unsuitable for enrollment in the study.
