About this study

Official title: The Effect of CL25216 on Hormonal Balance and Menstrual Health in Women With Primary Dysmenorrhea: A Randomized, Double-blind, Placebo Controlled Clinical Trial

This study is to evaluate the effects of CL25216 on hormonal balance and menstrual health in women with primary dysmenorrhea. Enrolled subjects will receive either CL25216 - 250 mg/day or placebo.

Read the detailed description

The purpose of this study is to evaluate the effect of CL25216 on hormonal balance and menstrual health in women with primary dysmenorrhea. A total of 80 female aged between 25-40 years will be included in the study. Assessment of inclusion and exclusion criteria will be done based on clinical and laboratory investigations. The eligible subjects will be randomized as per the computer-generated randomization list. The subjects will be assigned to either CL25216 - 250 mg or placebo arms at 1:1 ratio. The subjects will be instructed to take one capsule a day after breakfast for 84 days. Apart from primary and secondary outcomes, the study will also record the vital signs and adverse events to evaluate the herbal composition safety and tolerability. The safety assessment of the CL25216 will also include routine laboratory investigations on blood, urine and clinical chemistry at Screening visit and the final visit of the intervention.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Menstrual symptom Questionnaire

    The MSQ is a validated instrument designed to provide a concise assessment of menstrual pain symptoms. It consists of 25 items, each measuring the severity of climacteric symptoms on a scale from 1 (never) to 5 (always), in between 2 emans rarely, 3 means sometimes and 4 represents. The total score ranges from 29 to 125, with higher scores reflecting more severe menstrual pain symptoms.

    Measured: At day 1, 28, 56, and 84

Secondary outcomes (22)
  1. Pain duration

    No. of days subject experiencing the pain during menstrual cycle will be captured. As the no. of days increasing, QoL decreases.

    Measured: At day 1, 28, 56, and 84

  2. Female sexual function index

    The FSFI was developed as a brief, easy-to-administer, self-report tool for assessing key dimensions or domains of sexual function and quality of life in various populations of women. Female Sexual Function Index (FSFI), a widely used tool with six domains (Arousal, Desire, Orgasm, Lubrication, Satisfaction, and Pain). The total FSFI score ranges from minimum score of 2 and maximum score of 36. Greater Scores indicates better sexual function

    Measured: At day 1, 28, 56, and 84

  3. Resting Metabolic Rate (RMR)

    RMR reflects the caloric expenditure necessary for life, without accounting for physical activity or digestion, measured by using metabolic analyzer. Increase in RMR is a sign of improved metabolism

    Measured: At day 1, 28, 56, and 84

  4. Bodyweight

    The subject's body weight is measured using a digital weighing scale. An improvement is indicated when the body weight falls within the normal range based on the subject's demographic characteristics.

    Measured: At day 1, 28, 56, and 84

  5. BMI

    Body mass index is a calculated measure by considering the weight and height of a subject. A change in BMI from overweight to normal range is a positive indicator of healthy lifestyle.

    Measured: At day 1, 28, 56, and 84

  6. Waist Circumference

    Waist circumference is measured around the abdomen, just above the navel. This value is influenced by the subject's height and weight. A reduction in waist circumference indicates improvement in body weight, as well as decreased fat storage and deposition

    Measured: At day 1, 28, 56, and 84

  7. Hip Circumference

    It represents the maximum circumference measured around the buttocks. This measurement is influenced by the subject's height and weight. A reduction in this value indicates improvements in body weight, as well as a decrease in fat storage and deposition

    Measured: At day 1, 28, 56, and 84

  8. Quality of life questionnaire (Short Form -36)

    The 36-Item Short Form (SF-36) is a self-reported questionnaire used to assess overall health and quality of life. It consists of 8 domains, each scored on a scale from 0 to 100. Higher scores indicate a better quality of life and improved health status.

    Measured: At day 1, 28, 56, and 84

  9. Subjective self-assessments on hair quality

    This is a subjective measurement of hair quality by considering the hair fall rate. The Highest Possible Score is 5.

    Measured: At day 1, 28, 56, and 84

  10. Skin wrinkle assessment

    Visual assessment of skin wrinkles used to evaluate the appearance of skin aging and to determine the severity of wrinkles. This kind of assessment is typically done by a healthcare professional or dermatologist and involves examining the skin surface to identify and score wrinkles. Grade ranging from 0 to 9 where 0 represents no wrinkles and 9 represents deep wrinkles.

    Measured: At day 1, 28, 56, and 84

  11. Subject's self-assessment of skin Questionnaire

    As the perception of the skin radiance is subjective, a self-assessment has been performed through a questionnaire. The scores range from 0 to 10, with higher scores indicating better skin quality in terms of complexion, smoothness, texture, elasticity, and hydration

    Measured: At day 1, 28, 56, and 84

  12. HOMA-IR

    HOMA-IR is a simple and widely used method to estimate insulin resistance (IR) in perimenopause/menopause. HOMA-IR can be useful in assessing cardio metabolic risk

    Measured: At day 1, 28, 56, and 84

  13. Free testosterone

    Testosterone in females is produced by the ovaries, adrenal gland, and peripheral conversion of precursors like DHEA/androstenedione in fat/skin cells. Decrease in testosterone level results in increased pain severity.

    Measured: At day 1, 28, 56, and 84

  14. Total testosterone

    Testosterone in females is produced by the ovaries, adrenal gland, and peripheral conversion of precursors like DHEA/androstenedione in fat/skin cells. Decrease in testosterone level results in increased pain severity.

    Measured: At day 1, 28, 56, and 84

  15. Estradiol

    Estradiol is the most potent and biologically active form of estrogen in humans produced majorly by ovaries, followed by adrenal. Fluctuations in this hormone impacts menstrual pain.

    Measured: At day 1, 28, 56, and 84

  16. LH

    It is a hormone made by the pituitary gland that plays a key role in the reproductive system of females. Changes in LH levels cause ovulatory changes.

    Measured: At day 1, 28, 56, and 84

  17. FSH

    It is a hormone produced by the pituitary gland and plays a crucial role in the reproductive systems of females. Changes in FSH results in disturbed menstrual health.

    Measured: At day 1, 28, 56, and 84

  18. LH:FSH

    This marker is to evaluate the diagnosis of ovarian dysfunction. Increase in this value reflects the follicular arrest and anovulation.

    Measured: At day 1, 28, 56, and 84

  19. Anti-Mullerian hormone

    AMH (Anti-Müllerian Hormone) is a marker of ovarian reserve, reflecting the number of remaining follicles in the ovaries. AMH testing could help to assess the menstrual quality of life.

    Measured: At day 1, 28, 56, and 84

  20. TNF-alpha

    Tumor necrosis factor-alpha (TNF-alpha) is a potent, pro-inflammatory cytokine primarily produced by macrophages and monocytes, acting as a critical mediator of systemic inflammation. Increase in this concentration causes strong uterine contractions and pain.

    Measured: At day 1, 28, 56, and 84

  21. IL-6

    Interleukin-6 (IL-6) is a key pro-inflammatory cytokine significantly elevated in the plasma and menstrual blood of women with primary dysmenorrhea. Increase in this concentration promotes uterine contractions and causes pain.

    Measured: At day 1, 28, 56, and 84

  22. GLP-1

    Glucagon-like peptide-1 (GLP-1) is a crucial metabolic hormone released from intestinal L-cells upon food intake that regulates blood sugar and appetite. Increasing in GLP-1 aids in weight management and metabolism.

    Measured: At day 1, 28, 56, and 84
