The purpose of this study is to learn how the medicine called itraconazole and food changes how the body processes another study medicine called PF-07258669 in older adults or healthy adults. The study medicine PF-07258669 is developed for the treatment of unintended weight loss in older adults. People with this condition have decreased appetite and food intake, which is an important reason for poor nutrition and health results in people with unintended weight loss. The study has two parts: Part A and Part B. The study is seeking participants who: 1. Are males or females who can no longer have children. 2. Part A Only: Are at least 65 years old and in reasonably good health. Part B Only: Are at least 18 years old and in good health. 3. Part A Only: Have a body mass index (BMI) of 16 to 27 kilogram per meter squared and a total body weight of more than 40 kilograms (88 pounds). Part B Only: Have a BMI of 16-32 kilogram per meter squared and a total body weight of more than 50 kilograms (110 pounds). For Part A: Participants will take the study medicine PF-07258669 as tablets by mouth once on Day 1 at the study clinic and stay at the clinic for about 12 days. Then starting on Day 4, participants will take itraconazole as liquid by mouth for eight days. On Day 7, itraconazole will be taken together with PF-07258669. For Part B: Participants will take the study medicine PF-07258669 as tablets by mouth once on Day 1 without breakfast at the study clinic and stay at the clinic for about 7 days. On Day 4, participant will take the study medicine after breakfast. A different group of participants will follow a similar procedure, but they will take the medicine after breakfast on Day 1 and without breakfast on Day 4. For Parts A and B: At the clinic, the study team will observe the participants and take urine and blood samples to look at the levels of PF-07258669.
