What is the purpose of this trial?

This trial aims to evaluate the effectiveness of a 24-week weight loss program for women with PCOS, a condition affecting hormone levels, who also face obesity challenges. The program, called STREAM, includes meal replacements, dietician guidance, and regular specialist check-ins. Researchers seek to determine the extent of weight loss and improvements in health, such as insulin sensitivity. Women who are not pregnant, have a BMI of 30 or higher, and are referred to a specific weight management clinic may be suitable candidates. As an unphased trial, this study offers participants the chance to contribute to important research that could enhance weight management strategies for women with PCOS.

Will I have to stop taking my current medications?

The trial requires that you stop taking certain medications that impact weight, such as Liraglutide, Semaglutide, Tirzepatide, Naltrexone/Buproprion, and Orlistat, as well as androgen supplements like Testosterone and DHEAS. If you are currently using these, you would need to stop before participating.

What prior data suggests that the STREAM program is safe for participants?

Research has shown that intensive weight loss programs like STREAM are generally safe for people with PCOS (polycystic ovary syndrome). These programs emphasize lifestyle changes, such as meal replacements and guidance from dietitians, and are often the first recommended step for weight loss in women with obesity and PCOS. Studies have found these lifestyle changes to be well-tolerated, with no major safety concerns reported. Participants typically experience improvements in weight and other health measures without negative effects. Thus, the STREAM program is considered a safe option for managing weight and improving health related to PCOS. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the STREAM program for weight loss in individuals with PCOS and obesity because it combines several tailored approaches into one comprehensive plan. Unlike traditional treatments that might focus solely on diet or medication, the STREAM program integrates meal replacements, personalized dietician guidance, and regular check-ins with bariatric specialists over a 24-week period. This multifaceted approach aims to provide more sustainable weight loss by addressing both dietary habits and medical oversight, which could lead to better long-term health outcomes for participants.

What evidence suggests that the STREAM program might be an effective treatment for PCOS?

Research has shown that losing weight can improve key symptoms of PCOS, such as hormone balance and regular periods. One study found that participants lost between 2.32 and 7.87 kilograms over a year, depending on the type of support they received. Another review found that weight loss programs can enhance how the body uses blood sugar in individuals with PCOS. These findings suggest that the STREAM weight loss program, which all participants in this trial will undergo, might help people with PCOS lose weight and improve their overall health. ^{1 2 5 6 7}

Published Research Related to This Trial

In a study of 27 obese patients with PCOS who did not respond to lifestyle modifications, treatment with semaglutide led to an average weight loss of 7.6 kg after three months, with 80% of participants achieving at least a 5% reduction in body weight.

Semaglutide treatment not only resulted in significant weight loss but also improved insulin sensitivity and normalized menstrual cycles in 80% of responsive patients, all with minimal side effects.
