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

  • Women aged 18 to 45 at the time of signing the ICF;
  • Clinically diagnosed hyperprolactinemia, with or without pituitary PRL tumor;
  • Agree to and abide by the adoption of effective measures during the study period (from signing the ICF to 4 weeks after the last administration of the drug);
  • voluntarily signed the ICF, could understand and abide by the requirements of this research protocol, and were followed up regularly and on time.

Exclusion criteria

Exclusion Criteria:

  • Women who are pregnant or breastfeeding;
  • Those who have previously received carbergoline treatment or radiotherapy, or have a history of allergy to ergol preparations or their derivatives;
  • The presence of other types or mixed pituitary tumors;
  • hyperprolactinemia syndrome caused by hypothalamic or other intracranial lesions;
  • hyperprolactinemia syndrome caused by other systemic diseases;
  • Laboratory tests during the screening period meet any of the following conditions:

    1. (AST) or alanine aminotransferase (ALT) > 2 times , or total (TBIL) > 1.5 times ULN, or serum creatinine (Cr) or UREA (UREA)/urea nitrogen (BUN) > 2 times ULN;
    2. Those who are positive for surface antigen, antibody, antibody and Treponema pallidum antibody;
    3. Hyperprolactinemia: Screening tests show that the PRL recovery rate is less than 40%;
  • Those who have received ovulation-inducing agents, drugs that may cause an increase in PRL or other prohibited combination drugs within 4 weeks prior to screening;
  • The patients not suitable for participating in this clinical study due to other reasons.
Terms in these criteria, in plain language(8)

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.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
