The study medicine PF-07258669 is being developed for the treatment of unintended weight loss in older adults.

The study will include * Screening period for up to 4 weeks * Pre-treatment period of 2 weeks * Treatment period of 16 weeks : study drug (PF-07258669 or matching placebo) * Follow-up period of 4 weeks The study requires answering questionnaires and use of digital devices at home to measure blood pressure and physical activity.
