This study is to test how well and safely the medicine Suzetrigine (SUZ) works for pain from diabetic peripheral neuropathy (DPN). DPN is when people with diabetes have nerve damage that causes pain in their legs and feet. To join this study, you need to weigh more than 45 kilograms (about 99 pounds) and have a body mass index (BMI) between 18.0 and 40.0. BMI is a number that helps to know if your weight is healthy based on your height. You must have diabetes type 1 or 2 with a special blood test called HbA1c showing less than or equal to 9%. You should also feel pain in both your legs and feet. Your average pain score should be between 4 and 9 during a one-week period. You cannot join if you have more than 3 days without pain scores in that week or if you have been in another study with SUZ before. There are other rules for joining too.

• The study length and number of visits will be explained during the sign-up process.
• Participants may receive compensation for their time and travel.
• There are possible risks, which will be explained before you decide to join.
