About this study

Official title: Non-inferiority Between Acarbose and Prandial Insulin for the Treatment of Gestational Diabetes Mellitus: a Randomized Multicenter and Prospective Trial. ACARB-GDM Study.

Caring for women with gestational diabetes mellitus (GDM) is very time-consuming. Therapeutic strategy includes dietary and lifestyle measures and additional insulin therapy for 15 to 40% of the women with GDM if the glycemic targets are not achieved after a period of 1 to 2 weeks of diet. Insulin therapy is imperfect for the following main reasons: need for education (i.e. subcutaneous administration, dose titration), hypoglycemia and weight gain, limited acceptance and high cost. Psychosocial deprivation is associated with more cases of GDM and health accessibility may be unequal.

Glucosidase inhibitors (acarbose) reduce intestinal absorption of starch and reduce the rate of complex carbohydrate digestion. It mainly lowers postprandial glucose values and is used in type 2 diabetes for a long time. Less than 2% of a dose is absorbed as active drug in adults, with 34% of the metabolites found in the systemic circulation. Doses of up to 9 and 32 times the human dose were not teratogenic in pregnant rats or rabbits. Limited but reassuring data during pregnancy are available. Acarbose was well tolerated (little gestational weight gain, no hypoglycemia) with digestive discomfort in some women, balanced by treatment satisfaction as compared with insulin injections. Our hypothesis is that treatment aiming to control postprandial glucose values with acarbose as compared with prandial insulin injection will be as efficient and safe, but more convenient and less expensive.

Read the detailed description

Phase III study. Prospective, multicenter, non-inferiority, randomized, open-labelled and controlled study with two arms.

  1. In the 37 participating hospitals: selection of women with GDM who have unmet post prandial glycemic targets between 14 and 37 (+6 days) weeks of amenorrhea after at least 7 days of dietary and lifestyle measures. They may be treated with basal insulin to control pre prandial glucose values.
  2. Explanation of protocol, with signature of consent in case of acceptation.
  3. Randomization . Experimental group: The women will receive acarbose with a progressive increase of dose according to post prandial glucose values and digestive tolerance, with a maximal dose of 3 x 100 mg / day. The progressive titration of acarbose reduces gastro-intestinal side effects. Patients who have not reached the glycemic targets at this highest tolerated dose for at least one meal will receive instead prandial insulin therapy for each meal, whereas acarbose will be stopped. Failure to reach post-prandial target will be defined as 3 or more post-prandial glycaemic values ≥ 1.20 g/L for a given meal in a week (3 values out of 7) after the two weeks of dose adjustment.
  • Control group: The women will receive prandial insulin according to usual practice (routine care according to French recommendations): before each meal, with dose titration according to post prandial values. Basal insulin may be necessary in both arms to control pre-prandial glucose values. At delivery:
  • Maternal blood samples : 14 ml of blood will be collected at the same time as the sample routinely collected just before delivery for irregular agglutinin test measurement, when the women are perfused.
  • Cord fluid : 7 ml will be collected at the same as cord fluid pH is routinely measured just after delivery. There will be 5 aliquots to prepare. The aliquots previously labelled and stowed in the specific boxes for the study will be stored locally and will be transported to the "Centre de Ressources Biologiques"(CRB) of the Jean Verdier Hospital.
  1. Routine monitoring of the women with GDM in both arms, up to delivery. No use of other oral hypoglycemic agents during pregnancy.
  2. Last consultation three months after delivery.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • AcarboseDrug

    Also called Glucor 50 mg

    Women will receive acarbose at an initial dose of 50 mg once daily in the beginning of the meal for which the postprandial glucose value is the highest, with progressive increase every 2 days or more: adding a pill before another meal, and then increasing dose of acarbose to 100 mg if post-prandial glucose goals are not obtained, with a maximal dose of 3 x 100 mg / day.

  • Prandial insulinDrug

    Also called Rapid acting insulin analog

    Women will receive prandial fast-acting insulin according to usual practice (routine care according to French recommendations), i.e. one injection before each meal usually.

What is being measured

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

  1. Composite endpoint: birth weight ≥ 90th percentile for gestational age (large for gestational age: LGA) and/or neonatal hypoglycemia and/or shoulder dystocia and/or birth injury.

    LGA defined as birth weight greater than the 90th percentile for a standard French population

    • Neonatal hypoglycemia defined as at least a blood glucose value less than a 2.0 mmol/l during the two first days of life;
    • Shoulder dystocia, defined as vaginal cephalic delivery that requires additional obstetric manoeuvres to deliver the fetus after the head has delivered and gentle traction has failed. We will only consider rotational maneuvers such as Rubin II or Woods corkscrew or Jaquemier maneuvers
    • Birth injury defined as plexus injury or clavicle fracture.

    Measured: At delivery

Secondary outcomes (17)
  1. GLUCOSE CONTROL: Capillary glucose levels

    The women will be asked to perform 6 measures a day. Capillary glucose values will be retrieved from the glucose meter, and if not available, from the woman's diary.

    Measured: From two weeks after inclusion : 14 and 37 (+6 days) weeks of amenorrhea to delivery

  2. GLUCOSE CONTROL: HbA1c

    Centralized measurement

    Measured: At delivery

  3. GLUCOSE CONTROL: Need for and dose/day of basal and prandial insulin in both arms

    This information will be retrieved from the glucose meter, and if not available, from the woman's diary.

    Measured: At delivery

  4. Neonatal complications : Birth weight and height,

    Birth weight ≥ 4000g Birth weight ≥ 4500g

    Measured: At delivery

  5. Neonatal complications : Small for gestational age infant

    SGA: birth weight lower than the 10th percentile for a standard French population

    Medical Outcomes Study 36-Item Short-Form General Health Survey (SF-36)

    • use of analogic scales

    Measured: At delivery

  13. Side effects of drugs : Maternal hypoglycemia

    • Severe hypoglycemia: requiring assistance of another person to actively administer carbohydrates, glucagon, or take other corrective actions. Plasma glucose concentrations may not be available during an event, but neurological recovery following the return of plasma/capillary glucose to normal is considered sufficient evidence that the event was induced by a low plasma/capillary glucose concentration.
    • event during which typical symptoms of hypoglycemia are accompanied by a measured capillary glucose concentration <70 mg/dL (<3.9 mmol/L).
    • Asymptomatic hypoglycemia: event not accompanied by typical symptoms of hypoglycemia but with a measured capillary glucose concentration <60 mg/dL (<3.3 mmol/L).

    Measured: during the 7 months of treatment

  14. Gastro-intestinal side effects

    The events occuring during the last 14 days of pregnancy or gastro-intestinal side effects leading to treatment withdrawl

    Measured: from two weeks after inclusion : 14 to 36 weeks of gestation to delivery

  15. Results of oral glucose tolerance test and HbA1c measurement

    Test will be performed by the women before follow up visit

    Measured: 3 months after delivery

  16. Infant anthropometrics.

    These data will be collected from children's health record

    Measured: At month 1, month 2 and month 3

  17. Conservation of serum and plasma; cord fluid. The samples may be used for further analyses ancillary studies and which could be beneficial for GDM care based on evolution in scientific knowledge.

    • The blood samples will be collected at the same time as the sample routinely collected just before delivery for irregular agglutinin test measurement.
    • Cord fluid will be collected

    Measured: within 10 years after the end of the study

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: difficulty in recruiting). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Composite endpoint: birth weight ≥ 90th percentile for gestational age (large for gestational age: LGA) and/or neonatal hypoglycemia and/or shoulder dystocia and/or birth injury. (time frame: At delivery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03380546, which also lists 5 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
