What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores a new treatment, NNC0487-0111 (also known as Amycretin), to determine its effects on obesity or type 2 diabetes and its impact on the effectiveness of birth control pills. Participants will begin with a daily pill for 18 weeks, then switch to an injection for 9 weeks. The study aims to last about 35 weeks in total. Women who cannot have children and have a BMI between 25 and 39.9 might be suitable for this trial. As a Phase 1 trial, the research focuses on understanding how this new treatment works in people, offering participants the unique opportunity to be among the first to receive it.

Do I need to stop my current medications to join the trial?

You may need to stop taking certain medications. The trial excludes those using drugs that interfere with metabolic CYP pathways, like St. John's Wort, ginseng, garlic, milk thistle, and echinacea, within 14 days before screening. Routine vitamins and occasional use of acetaminophen, ibuprofen, and aspirin are allowed.

Is there any evidence suggesting that NNC0487-0111 is likely to be safe for humans?

Research has shown that NNC0487-0111, also known as amycretin, is generally well-tolerated in people. Studies involving individuals with overweight or obesity suggest that the treatment is safe, with a safety profile similar to other weight management treatments like GLP-1 and amylin.

In one study, researchers administered NNC0487-0111 to individuals with a body mass index (BMI) between 27 and 39.9. Participants tolerated the treatment well, with no major safety issues reported. Some side effects, such as nausea or mild stomach problems, are common with treatments like GLP-1, but they are usually manageable.

These results support further testing of NNC0487-0111, though it is important to note that this research is still in its early stages. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

NNC0487-0111 is unique because it introduces a novel approach to treating obesity by using both oral and subcutaneous (s.c.) dosing methods. Unlike standard treatments, which often involve lifestyle changes or medications like orlistat and liraglutide, NNC0487-0111 uses a dose-escalation strategy that might offer more personalized and potentially effective management of obesity. Researchers are excited about this treatment because it could provide a new mechanism of action that differs from existing options, potentially leading to more effective weight management solutions for patients.

What evidence suggests that NNC0487-0111 might be an effective treatment for obesity?

Research has shown that NNC0487-0111, which participants in this trial will receive, could effectively treat obesity. This medicine mimics two natural hormones, amylin and GLP-1, which help control hunger and blood sugar levels. Previous studies found that NNC0487-0111 led to greater weight loss compared to some existing treatments. Specifically, one study showed that participants lost more weight than those using the popular obesity drug, Wegovy. This suggests that NNC0487-0111 could be a strong option for people wanting to manage their weight. ^{2 4 6 7 8}

Published Research Related to This Trial

A review of nine systematic reviews found that pharmacological therapies for obesity, including liraglutide, orlistat, and naltrexone-bupropion, are effective in reducing weight compared to placebo.

Orlistat not only aids in weight loss but also significantly improves metabolic markers like fasting blood glucose and cholesterol levels, although it is associated with gastrointestinal side effects such as diarrhea and nausea.

Pharmacological Treatment for Obesity in Adults: An Umbrella Review. Khalil, H., Ellwood, L., Lord, H., et al.[2020]

In a review of 28 trials involving orlistat, sibutramine, and rimonabant, rimonabant and orlistat were associated with a significantly higher risk of discontinuation due to adverse events, with rimonabant having the highest risk ratio of 2.00.

The most common reasons for discontinuation were gastrointestinal issues for orlistat (40%) and psychiatric issues for rimonabant (47%), highlighting the importance of monitoring side effects in patients using these medications.

Obese women are at a higher risk for unintended pregnancies and thromboembolic events, making careful selection of contraceptive methods crucial; progestin-only contraceptives and intra-uterine devices are preferred options.

While obesity does not increase the failure rate of most contraceptive methods, bariatric surgery can complicate contraceptive choices due to potential gastrointestinal malabsorption, making oral contraceptives less reliable.

Women with obesity were primarily prescribed progestin-only pills (44%) compared to normal-weight women who were mostly given combined hormonal contraception (60%), highlighting a significant difference in contraceptive prescribing practices.

Women with obesity had a higher discontinuation rate of contraceptive methods within the first year (33% vs. 25% for normal-weight women), with bleeding disturbances being the most common reason for stopping, indicating potential challenges in adherence to treatment.

The combination of phentermine and topiramate is currently the most effective FDA-approved treatment for obesity, followed by lorcaserin and bupropion/naltrexone.

Effective obesity management should consider not only medication efficacy but also comorbidities, drug interactions, and personalized treatment approaches based on individual genetic profiles.

In a study of 258 individuals with obesity or overweight in Switzerland, 71.3% of those receiving reimbursed liraglutide 3.0 mg achieved significant weight loss targets at Week 16, indicating its efficacy in real-world settings.

By Month 10, participants who met the initial weight loss criteria experienced an average total weight loss of 12.4% from baseline, demonstrating that liraglutide can lead to clinically meaningful weight reduction over time.

Most high-quality studies indicate that oral contraceptive pills are generally effective for obese women, similar to their effectiveness in non-obese women, although data for women with severe obesity is limited.

Non-oral contraceptives typically maintain their effectiveness in obese women, but the combined hormonal patch and oral levonorgestrel emergency contraception may be less effective in this population.

There are three main drugs approved for long-term obesity treatment: orlistat (5-8 kg weight loss but with gastrointestinal side effects), lorcaserin (4-7 kg weight loss with few side effects), and a combination of phentermine and topiramate (8-10 kg weight loss, but requires pregnancy verification).

For patients with chronic diseases like diabetes or depression, it's important to choose medications that not only treat the condition but also promote weight loss, as some drugs can cause weight gain or have a neutral effect.

Phentermine is an effective short-term weight loss medication that can lead to a 5-15% reduction in weight, but it has common side effects like dry mouth and increased blood pressure, and tolerance may develop with prolonged use.

Orlistat, which is not absorbed systemically and thus has fewer systemic side effects, can also lower cholesterol but is limited by its frequent dosing and gastrointestinal side effects.

Phentermine/topiramate extended-release (PHEN/TPM ER) and lorcaserin are effective new medications for long-term weight management, with PHEN/TPM ER showing superior weight loss compared to lorcaserin based on phase III trials involving multiple participants.

Both medications are generally well-tolerated, but they come with specific safety concerns: PHEN/TPM ER may cause increased heart rate and psychiatric effects, while lorcaserin has risks of valvulopathy and cognitive impairment, necessitating careful monitoring in patients.

Tolerability and safety of the new anti-obesity medications. Hainer, V., Aldhoon-Hainerová, I.[2021]

New generation anti-obesity medications, such as orlistat, phentermine/topiramate, and liraglutide 3.0 mg, have varying safety profiles, with some presenting significant risks like fetal toxicity and gallstone disease, while others mainly cause transient tolerability issues.

Despite their effectiveness in weight loss, the prescription rates for these medications are low, partly due to safety concerns and the need for more long-term data to better understand their risk-benefit profiles.
