This research aims to establish a Phase-2 master protocol framework to evaluate the safety and effectiveness of various investigational treatments for chronic weight management in adults with obesity or overweight. The study sets common entry criteria for participants across multiple specific intervention groups, called intervention-specific appendices (ISAs), which may begin independently as new treatments become available for clinical testing. The overall results will be reported after all ISAs are completed. The study involves multiple investigational drugs administered either by injection (subcutaneously) or orally. These include LY3305677, LY3841136, Tirzepatide, LY3549492, LY3532226, and placebo treatments matching the administration methods of the active drugs. Each ISA will detail the specific intervention procedures. Treatments are given according to the ISA schedules as participants are assigned to different groups. Participants will be involved from screening through treatment and monitoring phases, where their body weight stability and other health parameters are assessed. Researchers will track the number of participants allocated to each ISA during the first six weeks. Safety and efficacy will be evaluated throughout the study, which includes regular assessments and adherence monitoring. The study includes adults aged 18 to 75 with specific body mass index (BMI) criteria and weight stability prior to enrollment.

Researchers are evaluating the safety and effectiveness of Vagus Nerve Stimulation (VNS) Therapy as an additional treatment compared to no stimulation in people with treatment-resistant depression. This prospective, multi-center, randomized, controlled, blinded trial focuses on reducing depressive symptoms over 12 months using multiple depression rating scales. The study follows guidelines from the Centers for Medicare and Medicaid Services regarding evidence development for this treatment. Participants receive implantation of the VNS device, which delivers stimulation to the vagal nerve. After a minimum two-week period post-implantation, participants are randomly assigned to either active VNS treatment or no stimulation control, with outcomes observed for 12 months. Following this randomized phase, all participants enter an open-label extension where those in the control group receive active stimulation. Additional subjects may join this open-label study for up to five years to further assess long-term effects. Throughout the study, participants undergo regular assessments including the Montgomery Åsberg Depression Rating Scale (MADRS), WHO Disability Assessment Schedule, Health Outcome Scale, Clinical Global Impressions Scale, and Suicidality Tracking Scale. Researchers monitor response rates, remission times, duration of effects, and adverse events from implantation through 12 months. This comprehensive evaluation includes safety monitoring and functional outcome measures to understand the impact of VNS therapy on depression and related disabilities.

Researchers are evaluating how tirzepatide affects body weight and cardiovascular risk factors in adolescents with obesity who also have multiple weight-related health issues. This Phase 3 study aims to assess the safety and effectiveness of tirzepatide combined with healthy nutrition and physical activity. The study includes adolescents aged 12 to 17 years with obesity defined by a high body mass index (BMI) and at least two weight-related comorbidities such as hypertension, prediabetes, or high triglycerides. Participants will receive either tirzepatide or a placebo, both administered by subcutaneous injection once weekly during the primary 72-week study period. Alongside medication, all participants will follow lifestyle interventions focusing on nutrition and physical activity. After completing the initial 72 weeks and a 4-week safety follow-up, eligible participants who have not been off treatment for more than 12 weeks can continue tirzepatide treatment for an additional 156 weeks with ongoing lifestyle support. Throughout the study, up to 23 visits will monitor participants' BMI changes and improvements in weight-related health conditions. Researchers will measure the percentage change in BMI and assess whether participants show significant improvement or normalization in at least two comorbidities without new or worsening conditions over 72 weeks. Safety and efficacy will be closely tracked during the treatment periods and follow-up visits to understand tirzepatide's impact on adolescent obesity and related health risks.
