Pilot Study on a Dietary Supplement With EndoGen™ as Adjunct Therapy in Women With Endometriosis

This is a small, early-stage study designed to test whether a four-month treatment with EndOK Green-a supplement made from EndoGen (TM), a mixture based on parsley extract (Petroselinum crispum), rosemary extract (Rosmarinus Officinalis L.), and selenium-can help reduce pain and lower the need for NSAIDs in women with moderate endometriosis (classified as stage 2 to 4 by the American Fertility Society). EndOK Green extract contains natural compounds like flavonoids (apigenin and luteolin), myristicin, and apiol, which may help ease symptoms through anti-inflammatory, antioxidant, and hormone-balancing effects, with fewer side effects than standard medications. This study includes a 4-week observational run-in period designed to exclude patients who show a clinically meaningful response without receiving any additional treatment.

Following this period, the investigational product will be administered for 16 consecutive weeks. Treatment responders will be defined as patients who meet either of the following criteria during the last 4 weeks of the treatment phase, specifically during the menstrual period:

A reduction of at least 20% from baseline on the VAS100 pain scale (e.g., if baseline pain is 8, a score of 6.4 is sufficient), and/or a 50% reduction from baseline in exposure (duration or dosage) of NSAIDs or other pain relievers.

Inclusion criteria

for the Initial Run-In Phase

• Written informed consent, signed and dated personally by the patient.
• Female between the ages of 18 and 45 (including limits), with no race limitation.

• Endometriosis with a grade 2 (mild) to grade 4 (severe) AFSr score, whether or not treated with sex hormones, contraceptives, or any other specific treatment, stable for a minimum of 2 months. Note: In a first phase of the investigation, patients in class 2 and 3 will be recruited, while in a second phase, patients in class 4 will also be recruited.
• 10-point Visual Analogue Scale (VAS) score of pain due to endometriosis of at least 4 for at least 2 days in the 4 weeks prior to run-in.
