Study summary

The study aims to assess the efficacy of folic acid supplementation at two doses (1 mg/day and 5 mg/day) in the management of hot flashes associated with adjuvant endocrine therapy among premenopausal breast cancer patients.

Read the detailed description

Folic acid is one of the B vitamins that when absorbed into its active form is converted to tetrahydrofolate. Folate is an essential cofactor for the biosynthesis of norepinephrine and serotonin. Studies have also noted that folate, with a mechanism like hormone replacement therapy (HRT), can improve hot flashes by interfering with monoamine neurotransmitters called norepinephrine and serotonin .The purpose of the current study is to investigate the role of folic acid administration at two different doses (1 mg/day and 5 mg/day) in the management of hot flashes associated with adjuvant endocrine therapy in patients with breast cancer.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Females older than 18 years
  • Diagnosed with confirmed breast cancer and currently treated with an endocrine
  • Experiencing bothersome hot flashes at least 14 times/week
  • Taking the treatment within 6 months to two years.
  • Able to read and write to complete the study questionnaires and hot-flash diary.

Exclusion criteria

Exclusion Criteria:

  • Known to folic acid
  • Patients who have been treated with selective serotonin reuptake inhibitors (SSRIs) within the past 30 days.
  • breast cancer
  • Renal impairment (Serum creatinine > 2 mg/dl)
  • Significant liver disease: liver enzymes 2 folds the upper normal limit
  • Taking other medication for hot flashes
  • Medications inducing hot flashes such as (Clomiphene, Opioids, Nifedipine, Prednisone)
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Adjuvant and neoadjuvant

Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

What researchers measure

Primary outcomes

  1. Reduction in Hot Flash Frequency and Severity

    It is measured using the daily hot flash diary, which tracks the number and intensity of hot flashes over the study period.

    Time frame: 3 months

Secondary outcomes

  1. Improvement in Quality of Life

    Assessed through the Hot Flash Related Daily Interference Scale (HFRDIS), which evaluates how hot flashes interfere with daily activities and overall well-being.

    Time frame: 3 months

  2. Correlation with Folic Acid Blood Levels

    Folic acid levels in the blood will be measured to explore the relationship between serum folate concentrations and changes in hot flashes symptoms.

    Time frame: 3 months
