About this study

Official title: Antiresorptive Drug Continuation Compared With Drug Holiday in Cancer Patients Needing Tooth Extraction - A Randomized Clinical Trial

The aim of this trial is to evaluate high-dose antiresorptive drug holiday related to tooth extraction with primary mucosal closure (surgical extraction) including how a drug holiday affects the health related quality of life.

Research question: Does a drug holiday have any influence on health related quality of life or the incidence of developing osteonecrosis of the jaw after surgical tooth extraction? The investigators hypothesize that a drug holiday 1 month before to 3 months after surgical tooth extraction in cancer patients do not influence the development of osteonecrosis of the jaw and may even affect the health related quality of life negatively.

Read the detailed description

Osteonecrosis of the jaw is a known adverse reaction to antiresorptive medication, including bisphosphonate and denosumab. The globally accepted term is Medication-Related Osteonecrosis of the Jaws (MRONJ). Since 2003 there has been a worldwide focus at medication-related osteonecrosis, even though there still exist several of unanswered questions - one of them is the effect of a drug holiday in relation to tooth extraction. A drug holiday is a temporary discontinuation of a drug and has been suggested among risk reduction strategies in the literature. It is still unknown whether a drug holiday plays a significant role in relation to tooth extraction for the development of osteonecrosis. The investigators want to investigate the importance of an antiresorptive drug holiday (bisphosphonate, denosumab) in relation to tooth extraction.

The aim of this trial is therefore to clarify the meaning of high-dose antiresorptive drug holiday related to tooth extraction with primary mucosal closure in cancer patients and reveal how a drug holiday affects the health related quality of life. A continuation of the patients' antiresorptive treatment can possibly lead to increased risk of osteonecrosis of the jaw, but with the operation procedure with primary closure it is unlikely. It is beneficial for the cancer patients to continue the high dose antiresorptive therapy because a drug holiday is a stop in their anti-cancer treatment with risk of increased pain as well as unwanted skeletal events to occur, and potentially progress of metastases to follow.

Continuation of antiresorptives in relation to tooth extraction (surgical tooth removal)

What participants receive

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

  • Continuation of antiresorptives in relation to tooth extraction (surgical tooth removal)Other

    We want to investigate the importance of an antiresorptive drug holiday (bisphosphonate, denosumab) in relation to tooth extraction. The experimental intervention in this trial is drug continuation starting before tooth extraction with primary closure.

    We simply ask the participating cancer patients to continue their high dose antiresorptive treatment for 4 months (intervention-period: 1 month pre-operative, 3 months post-operative) instead of taking a drug holiday.

What is being measured

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

  1. Development of osteonecrosis of the jaw (ONJ) or incomplete healing at 3 months follow-up

    The outcome assessor has 3 options for registration related to ONJ occurrence:

    • Complete healing = mucosal covering = no sign of ONJ, defined as complete wound healing; Intact mucosa, that is total mucosal covering over the tooth extraction area.
    • Incomplete healing = presence of fibrin covering partly or over all mucosal operation area; Defined as the presence of fibrin at the surface of the operation area, thus still being a wound.
    • ONJ present, defined according to the AAOMS position paper 2014 (4), all three items have to be present:
    1. Current or previous treatment with antiresorptive agents.
    2. Exposed bone or bone that can be probed through an extraoral or intraoral fistula that has persisted for longer than 8 weeks.
    3. No history of radiation therapy to the jaws or obvious metastatic disease to the jaws.

    Measured: 3 months follow-up

  2. EQ-5D-5L: Change in patients health related quality of life from allocation/enrollment

    The patients are given the EQ-5D-5L questionnaire. The 5-level EQ-5D version (EQ-%D-5L) was introduced by the EuroQol Group in 2009 and consists of two pages: the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS). The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, serve problems and extreme problems. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state. The Danish dataset (SPSS syntax crosswalk values EQ-5D-5L Denmark) will be used to analyze patients´ responses.

    Measured: The patient will be asked to fulfill the EQ-5D-5L at allocation/enrollment and again at 1, 3 and 6 months follow-up.

Secondary outcomes (3)
  1. Pain from the jaw

    Pain from the jaw is registered by a Visual Analogue Scale (VAS). The investigator will give the patient a paper with a VAS, see attached appendix 3, and ask following question: "On a scale from 0 to 10, where 0 is no pain and 10 is the worst thinkable pain, mark at the scale how much pain you feel from your jaw at tooth operation site".

    Measured: This is asked prior to tooth extraction (time 0), at suture removal (time 10-14 days), at 1-month follow-up and at 3 and 6 months follow-up and is registered in the datasheet.

  2. Incidence of unwanted skeletal events

    The patient is giving a simple questionnaire, where they have to answer yes or no to following question: "Have you visited your own doctor or been hospitalized because of fractures or other skeletal complications during this trial period - yes or no. If yes, please write why." See attached appendix 4: Skeletal-related event questionnaire

    Measured: Incidence (number of) unwanted skeletal events during the period and is registered at 3 and 6 months follow-up.

  3. Progression of cancer disease

    The tumor-evaluation will be done by the oncologic doctor in due to their departments routine.

    Measured: The patient will be weighted at baseline, time of tooth removal, 1 month follow-up, 3 and 6 months follow-up visit.
