What is the purpose of this trial?

This trial explores how pollen extracts might relieve menopause symptoms, such as hot flashes and mood changes. The study compares two types of pollen extracts, Graminex WSPE (water-soluble pollen extract) and Graminex LSPE (lipid-soluble pollen extract), against a placebo to determine which is most effective in reducing these symptoms. Women who haven't had their period for over a year and experience moderate menopause symptoms may be suitable for this study. Participants will provide feedback on their symptoms throughout the trial. As a Phase 2 trial, this research focuses on measuring the treatment's effectiveness in an initial, smaller group of people.

Will I have to stop taking my current medications?

The trial requires participants to maintain their current medications as much as possible throughout the study. However, if you are taking medications, supplements, or consuming food/drinks that might affect the study's results, you may need to stop or adjust them as assessed by the Qualified Investigator.

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

Research has shown that pollen extract treatments, like those in this study, are generally safe. Most treatments do not cause reactions. In some cases, mild side effects may occur, but these are usually not serious.

The pollen extracts used in this trial withstand digestion and heat, allowing them to pass through the body without breaking down. This reduces the risk of side effects.

Since this study is in Phase 2, earlier studies have already provided some evidence of safety. While specific details on side effects are not available here, the continued testing of these extracts suggests they are generally well-tolerated. Based on past research, participants in this trial can reasonably expect the treatments to be safe. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about Graminex LSPE and WSPE because these treatments offer a unique approach to managing menopause symptoms. Unlike traditional hormone replacement therapies, which often involve synthetic hormones, Graminex extracts are derived from flower pollen. LSPE is rich in phytosterols, while WSPE contains a high concentration of amino acids, both potentially offering a natural alternative to hormone-based treatments. This could provide a safer option for individuals who are unable to use standard hormone therapies or prefer natural remedies.

What evidence suggests that this trial's treatments could be effective for menopausal symptoms?

Studies have shown that pollen extracts can significantly ease menopausal symptoms. A similar pollen extract, Sérélys®, reduced hot flashes, sleep problems, and mood swings. In this trial, participants will receive either Graminex LSPE or WSPE, both studied for their potential to affect hormones and reduce these symptoms. Previous studies on pollen extracts have also reported less irritability, tiredness, and vaginal dryness. These findings suggest that Graminex LSPE and WSPE may improve overall comfort during menopause. ^{1 2 3 5 6}

• Graminex LSPE
• Graminex WSPE
• Placebo

Trial Overview

The study tests the effects of two types of pollen extracts (WSPE and LSPE) against a placebo on menopausal symptoms. Women will rate their symptoms using the Menopause Rating Scale over 36 weeks to see if there's any difference between the treatments.

Published Research Related to This Trial

In a study of 30 patients with grass pollen allergy, Nasonex (mometasone furoate) demonstrated significant efficacy in relieving symptoms of allergic rhinitis, with 24 patients experiencing complete or marked relief after treatment.

The treatment was well tolerated with no adverse reactions reported during the 2-week period, and it effectively reduced eosinophil levels in the nasal mucosa, indicating its mechanism of action in alleviating allergy symptoms.
