Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Prospective double-blinded randomized clinical study. Aim of the study is to compare the effectiveness of Caphosol mouth rinses in prevention of oral mucositis as compared to 0.9% NaCl rinses. Patients will be randomized to receive either Caphosol or 0.9% NaCl rinses four times a day for seven days from the beginning of chemotherapeutic regimen. The same patient will be given the opposite rinse during the next chemotherapeutic regimen, so everyone will get both mouth rinses once during the trial.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study will be a double-blinded study so that the researchers or research nurses and the patients/parents are unaware of the solution used (Caphosol vs 0.9% NaCl). They both taste very similar and are packaged to ampules similar to each other. Since Caphosol consists of two solutions (A and B) which are mixed immediately before use, the investigators will apply the same procedure also in case of 0.9% NaCl solution (two vials of 0.9% NaCl will be mixed) to maintain blinding. Caphosol and 0.9% NaCl rinses will be relabeled to maintain blinding. Every patient will participate two times in the study. The treatment group allocation is based on randomization and will be performed once before participation for the first time. During another chemotherapeutic regimen, the same patient will automatically use another mouth rinse (Group 1 =\> Group 2 and Group 2 =\> Group 1). This dependence-effect caused by observations gathered from same patients will be taken into account when analysing the data. Blinding will be maintained throughout the study.

The investigators estimate that occurrence of oral mucositis as a side effect of chemotherapeutic treatment differs by 3-fold in different study arms (10% in Caphosol group, and 30% in 0.9% NaCl group). Power calculations using power of 0.8 and p-value of 0.05 indicate that the 70 children are needed to be recruited into each arm, i.e. two repeated measurements from 70 children are needed to have adequate statistical power. A drop-out of approximately 3-5% of patients has been taken into account and therefore the investigators plan to recruit 75 patients. Randomization will be performed using freely available and web-based MINIM-randomization software.

The data analysis will be performed on intention-to-treat principle. Mixed-effect regression methods will be used due to repeated observation within study subjects.

Specific methods used for this study:

* Oral mucositis will be assessed daily for all patients at the oncology ward and at home by use of the Children International Mucositis Evaluation Scale and World Health Organization oral mucositis scale.
* In the beginning of study, initial clinical evaluation will be performed by a pediatric dentist. During the stay at hospital, parents/patients (or nurses) will fill in the oral mucositis scales. At home, the patients/parents fill the scales. Scales will be filled in once a day for 14 consecutive days. Caphosol / 0.9% NaCl rinse treatment will last for only 7 consecutive days.
* The available medical and dental records will be audited for the frequency of oral mucositis.
* Oral samples will be collected by a pediatric dentist, and bacterial analyses will be performed by microbiologist at University of Tampere.
* Laboratory values and pain medications will be retrieved from electronic patient files (MIRANDA/Fimlab).
* Blood tests will be collected for possible later use in genetic studies.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Caphosol rinse group

Caphosol consists of two solutions (A and B) which are mixed immediately before use. Caphosol mouth rinse will begin concomitantly (the same day) with the beginning of chemotherapeutic drugs. It will be continued for seven consecutive days.

Group Type EXPERIMENTAL

Caphosol

Intervention Type DRUG

0,9% NaCl group.

0,9% NaCl consists of two solutions (A and B). Two vials of 0.9% NaCl will be mixed to maintain blinding. The study mouth rinse will begin concomitantly (the same day) with the beginning of chemotherapeutic drugs. It will be continued for seven consecutive days.
