What is the purpose of this trial?

This trial aims to determine if adding tirzepatide injections to a levonorgestrel IUD improves treatment outcomes for women with certain early-stage uterine conditions. These conditions include endometrial atypical hyperplasia or grade 1 endometrial cancer, which can worsen with excess weight. Researchers are testing tirzepatide, a weight-loss injection, and the levonorgestrel IUD, a hormone-releasing device, together to see if they reduce cancer cells in tissue samples. Women who are overweight or obese, diagnosed with one of these conditions, and prefer a non-surgical approach might be suitable for this study. As a Phase 2 trial, this study measures the treatment's effectiveness in an initial, smaller group, allowing participants to contribute to important medical research.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that tirzepatide is generally well-tolerated. Studies indicate that the cancer risk for those taking tirzepatide is similar to those not taking it, suggesting it does not increase cancer risk. One study found it helped reduce tumor size in mice, which is promising for its potential in cancer treatments.

For the levonorgestrel intrauterine device (LNG-IUD), research has shown it to be a safe and effective treatment. Trials have shown no side effects and suggest it may lower the risk of endometrial cancer. The LNG-IUD is often used in cancer prevention and management and has a good safety record.

Overall, both tirzepatide and the LNG-IUD have demonstrated positive safety profiles in research.12345

Why are researchers excited about this trial's treatments?

Researchers are excited about the combination of tirzepatide and a progestin IUD for endometrial cancer because it brings a fresh approach to treatment. Unlike traditional methods that often involve surgery or standard hormone therapies, this combination leverages tirzepatide, a new drug that acts on both GLP-1 and GIP receptors, which are pathways not typically targeted in endometrial cancer. This dual-action could potentially lead to better weight management and improved metabolic health, which are important factors in cancer treatment. Additionally, using a progestin IUD provides localized hormone delivery, which may reduce systemic side effects typically associated with oral or injectable hormone therapies.

What evidence suggests that this trial's treatments could be effective for endometrial cancer?

Research shows that tirzepatide, which participants in this trial will receive, can aid in weight loss, an important factor since obesity is linked to endometrial cancer. Studies have found that tirzepatide can reduce tumor size and may slow tumor growth in obesity-related cancers. Meanwhile, the levonorgestrel intrauterine device (LNG-IUD), also included in this trial, has been shown to lower the risk of endometrial cancer. Specifically, one study found that using the LNG-IUD led to a 93% reduction in abnormal thickening of the uterine lining. This trial will evaluate the combination of these treatments to potentially improve outcomes for women with early-stage endometrial cancer or precancerous conditions.24678

Are You a Good Fit for This Trial?

This trial is for overweight or obese women with endometrial atypical hyperplasia/endometrial intraepithelial neoplasia (AH/EIN) or grade 1 endometrial cancer. It's designed to see if a combination of tirzepatide injections and a levonorgestrel-releasing intrauterine device can improve treatment outcomes.
