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.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

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.

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.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

INR, PT and aPTT (clotting tests)

Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.

Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.

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.

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.

What researchers measure

Primary outcomes

  1. Mean Bleeding Index (Bl) at Week 12

    Gingival bleeding will be assessed as an invasive assessment of BI. It will be assessed for all evaluable surfaces of the facial and lingual/palatal gingiva with six sites per tooth. To perform the bleeding assessment, a round-ended probe will be inserted approximately 1 millimeter (mm) into the gingival sulcus at approximately 60 degrees and will be moved from the distal interproximal area to the mesial interproximal area. Presence/ absence of gingival bleeding will be assessed for 30 seconds after probing and will be scored on a 3-points scale ranging from 0 to 2, where 0 equal to (=) no bleeding after 30 seconds; 1= bleeding observed within 30 seconds of probing; 2= bleeding observed immediately on probing. Lower score will indicate an improvement in the symptoms.

    Time frame: At Week 12

Secondary outcomes

  1. Mean BI At Week 2 and 6

    Gingival bleeding will be assessed as an invasive assessment of BI. It will be assessed for all evaluable surfaces of the facial and lingual/palatal gingiva with six sites per tooth. To perform the bleeding assessment, a round-ended probe will be inserted approximately 1 mm into the gingival sulcus epithelium at approximately 60 degrees and will be moved from the distal interproximal area to the mesial interproximal area. Presence/ absence of gingival bleeding will be assessed for 30 seconds after probing and will be scored on a 3-points scale ranging from 0 to 2, where 0= no bleeding after 30 seconds; 1= bleeding observed within 30 seconds of probing; 2= bleeding observed an immediately on probing. Lower score will indicate an improvement in the symptoms.

    Time frame: At Week 2 and 6

  2. Mean Number of Bleeding Site (NBS) At Week 2, 6 and 12

    Gingival bleeding will be assessed as an invasive assessment of BI. It will be assessed for all evaluable surfaces of the facial and lingual/palatal gingiva with six sites per tooth. To perform the bleeding assessment, a round-ended probe will be inserted approximately 1 mm into the gingival sulcus epithelium at approximately 60 degrees and will be moved from the distal interproximal area to the mesial interproximal area. The presence/ absence of gingival bleeding will be assessed for 30 seconds after probing. The NBS for each participant will be calculated as the number of evaluable tooth sites with bleeding observed immediately on probing or within 30 seconds of probing.

    Time frame: At Week 2, 6 and 12

  3. Mean Overall Turesky Modification of the Quigley Hein Index (TPI) At Week 2, 6 and 12

    TPI will be a non-invasive assessment of supra-gingival plaque accumulation. The plaque will first be disclosed using a plaque disclosing dye solution. The TPI will be assessed for all evaluable surfaces of the facial and lingual surfaces of each scoreable tooth. Three scores will be recorded facially and three lingually, generating six scores per tooth. The disclosed plaques will then be scored using a 6-point scale ranging from 0 to 5, where 0= No plaque; 1= Slight flecks of plaque at the cervical margin of the tooth; 2= Thin, continuous band of plaque 1 mm or smaller at the cervical margin of the tooth; 3= Band of plaque wider than 1 mm but covering less than 1/3 of the area; 4= Plaque covering at least 1/3 but less than 2/3 of the area; 5= Plaque covering 2/3 or more of the crown of the tooth. Lower score will indicate an improvement in the symptoms.

    Time frame: At Week 2, 6 and 12

  4. Mean Interproximal TPI At Week 2, 6 and 12

    TPI will be a non-invasive assessment of supra-gingival plaque accumulation. The plaque will first be disclosed using a plaque disclosing dye solution. The TPI will be assessed for all evaluable surfaces of the facial and lingual surfaces of each scoreable tooth. Three scores will be recorded facially and three lingually, generating six scores per tooth. The disclosed plaques will be scored using a 6-point scale ranging from 0 to 5, where 0= No plaque; 1= Slight flecks of plaque at the cervical margin of the tooth; 2= Thin, continuous band of plaque 1 mm or smaller at the cervical margin of the tooth; 3= Band of plaque wider than 1mm but covering less than 1/3 of the area; 4= Plaque covering at least 1/3 but less than 2/3 of the area; 5= Plaque covering 2/3 or more of the crown of the tooth. Lower score will indicate an improvement in the symptoms.

    Time frame: At Week 2, 6 and 12

  5. Mean Modified Gingival Index (MGI) At Week 2, 6 and 12

    The MGI is a non-invasive visual assessment of gingival health. It will be assessed for all evaluable teeth. For each tooth, scores will be recorded and will be scored on a 5-point scale ranging from 0 to 4, where 0= Absence of inflammation, 1= Mild inflammation; slight or little change in color; little change in texture of any portion of the marginal/ papillary gingival unit, 2= Mild inflammation; criteria as above, but involving the entire marginal/ papillary gingival unit, 3= Moderate inflammation; glazing, redness, edema, and/ or hypertrophy of the marginal/ papillary gingival unit, 4= Severe inflammation; marked redness, edema and/ or hypertrophy of the marginal/ papillary gingival unit, spontaneous bleeding, congestion, or ulceration. Lower score will indicate an improvement in the symptoms.

    Time frame: At Week 2, 6 and 12

Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
