A Study of PF-08653945 and PF-08653944 for Overweight or Obesity (SOLIS-1)

This study, called SOLIS-1, is looking into the safety and effects of two investigational drugs, PF-08653945 and PF-08653944, for adults who are overweight or have obesity. You might receive one of these drugs alone, both together, or a placebo (an inactive substance). The main goal is to see how much your body weight changes from the start of the study to Week 48. You could be eligible if you are 18 or older and have obesity (BMI 30.0-50.0 kg/m2) or are overweight (BMI 27.0-<30.0 kg/m2) with at least one weight-related health issue like high blood pressure or sleep apnea. The study plans to enroll 872 participants, but its current recruitment status is unclear.
