This study is about testing a new drug called EN3835 to see if it works to treat a foot condition called plantar fibromatosis, also known as Ledderhose disease. **Plantar fibromatosis** is a condition where hard lumps develop on the bottom of the foot, causing pain. In this study, some participants will receive the actual treatment and others will receive a placebo (a substance with no active drug) to compare results.
**Key Points**:
- The study includes adults 18 and older who have foot pain due to plantar fibromatosis.
- Participants must avoid certain medications during the study and women must agree to use birth control.
- The study aims to ensure the treatment is safe and effective, but some people with certain health conditions or other foot issues may not qualify.
Participants should be able to walk and understand the study details before giving consent. This study will help determine if EN3835 is safe and can help with foot pain from plantar fibromatosis. If you have any other health problems or are pregnant or breastfeeding, you may not be eligible to participate.
