Obesity and type 2 diabetes mellitus (T2DM) represent major public health concerns in the aging Hispanic community. Tirzepatide, a novel dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist recently approved for the treatment of T2DM and obesity has been shown to be effective at reducing weight, improving markers of T2DM control, and improving cardiovascular health. Utilization of tirzepatide in the Hispanic community has been on the rise since FDA approval was issued, however the effects of tirzepatide use on functional outcomes in older Hispanic adults with obesity are not well established. Recent studies show that weight loss caused by tirzepatide may be driven by substantial loss of lean muscle mass, which may contribute to weakness and frailty, particularly among older adults. The proposed pilot study aims to evaluate how treatment with tirzepatide for 6 months affects muscle mass and function among older Hispanic adults, and if changes in muscle mass are linked to changes in functional status over the same time period.

This randomized phase III trial studies whether weight loss in overweight and obese women may prevent breast cancer from coming back (recurrence). Previous studies have found that women who are overweight or obese when their breast cancer is found (diagnosed) have a greater risk of their breast cancer recurring, as compared to women who were thinner when their cancer was diagnosed. This study aims to test whether overweight or obese women who take part in a weight loss program after being diagnosed with breast cancer have a lower rate of cancer recurrence as compared to women who do not take part in the weight loss program. This study will help to show whether weight loss programs should be a part of breast cancer treatment.

Therefore, this study looks at the effect of semaglutide on glucose levels in the body and other information about type 2 diabetes and obesity.

This study is open to adults who are at least 18 years old and have a body mass index of 27 kg/m² or more. People can take part if they have type 2 diabetes and if they are currently being treated only with diet and exercise or with specific diabetes medications. Only people who have previously not managed to lose weight by changing their diet can participate. The purpose of this study is to find out whether a medicine called survodutide (BI 456906) helps people living with overweight or obesity who also have diabetes to lose weight. Participants are divided into 3 groups by chance, like drawing names from a hat. 2 groups get different doses of survodutide and 1 group gets placebo. Placebo looks like survodutide but does not contain any medicine. Every participant has a 2 in 3 chance of getting survodutide. Participants inject survodutide or placebo under their skin once a week for about one and a half years. In addition to the study medicine, all participants receive counselling to make changes to their diet and to exercise regularly. Participants are in the study for about 1 year and 7 months. During this time, it is planned that participants visit the study site up to 14 times and receive 6 phone calls by the site staff. The doctors check participants' health and take note of any unwanted effects. The study staff also regularly measure participants' body weight. The results are compared between the groups to see whether the treatment works.

This study is researching experimental drugs called trevogrumab and garetosmab (called "study drugs") in combination with another drug, semaglutide (Wegovy®). This study will be done in 3 parts, Part A, Part B, and Part C where different study drugs will be tested. Part A of the study is focused on healthy participants. Part B and C of the study is focused on participants with obesity. The aim of Part A of the study is to see how safe and tolerable the study drug is in healthy participants. The aim of Part B and Part C of the study is to see how safe and effective the study drug is when combined with Wegovy. Parts A, B, and C of the study are looking at several other research questions, including: * What side effects may happen from taking the study drug * How much study drug is in the blood at different times * Whether the body makes antibodies against the study drug (which could make the drug less effective or could lead to side effects)

Frequently Asked Questions

How much do Weight Loss clinical trials in San Antonio, TX pay?

Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.

How do Weight Loss clinical trials in San Antonio, TX work?

After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across Weight Loss trials in San Antonio, TX 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length in San Antonio, TX for Weight Loss is 12 months.

How do I participate in a study as a "healthy volunteer"?

Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility in San Antonio, TX several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.

What does the "phase" of a clinical trial mean?

The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.

Do I need to be insured to participate in a Weight Loss medical study in San Antonio, TX ?

Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.

What are the newest Weight Loss clinical trials in San Antonio, TX ?

Most recently, we added Semaglutide for Type 2 Diabetes and Spinal Cord Injury, Retatrutide for Obesity and Tirzepatide for Muscle Health to the Power online platform.
