Brief Summary

The purpose of this study is to determine if the administration of Caphosol rinse, at the start of chemotherapy, will prevent the development of mucositis (greater than or equal to grade 2 in children, adolescents and young adults. This is a randomized, controlled trial.

Detailed Description

Oral mucositis, is a common and debilitating complication of cancer therapy. It is an inflammatory injury to the epithelial and sub-epithelial cells of the oral mucosa. The incidence and severity of oral mucositis depends on many factors including the age and diagnosis of the patient, the specific treatment regimen, underlying oral hygiene and genetic factors 2-4. This ranges from around 40% of patients getting chemotherapy for solid tumors to 70-90% of patients getting chemotherapy for before stem cell transplant.

Oral mucositis causes significant pain, interferes with eating, talking and swallowing, significantly diminishes enteral nutritional intake and has a substantial negative impact on quality of life. Patients may require hospitalization for management of the complications of mucositis, including poor nutrition, dehydration and pain. Injury to the oral mucosa also increases the risk of systemic infections. Finally, the development of oral mucositis may require delays or dose reductions in future chemotherapy courses, potentially jeopardizing disease cure rates.

Despite all that is known about the mechanism, course and complications of oral mucositis, there are no consensus guidelines on prevention or treatment of chemotherapy-induced oral mucositis and there is significant variation on approach to mucositis across treatment centers.

Caphosol (Jazz Pharmaceuticals, Inc. Palo Alto, CA) was designed in part to replace the normal ionic and pH balance of the oral cavity and been used to prevent and/or treat oral mucositis. Caphosol is hypothesized to diffuse into epithelial intracellular spaces and permeate mucosal lesions in oral mucositis.

This study is a randomized, controlled trial evaluating the use of topical Caphosol therapy to prevent oral mucositis (Grade ≥ 2) in children, adolescents and young adults undergoing chemotherapy. At the time of enrollment, patients will be randomized to either the control arm or the Caphosol arm. The treatment period will extend from the start of chemotherapy and continue for 7 days after completion of chemotherapy AND until the ANC is > 500 after nadir (count recovery) or until the symptoms of oral mucositis resolve; whichever occurs last.

Study patients will be recruited from the MACC Fund Center and the oncology inpatient service. Study entry is open to patients regardless of gender or ethnic background. While there will be every effort to seek out and include females and minority patients, the patient population is expected to be no different than that of other oncology studies at the Medical College of Wisconsin.

Conditions

Oral Mucositis

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: PREVENTION
• Blinding Strategy: NONE

Study Groups

Caphosol Arm

Caphosol Arm: Subjects randomized to the Caphosol Arm will use Caphosol 4 times per day from the start of chemotherapy until 7 days after the completion of chemotherapy AND until the ANC is \>500 after count recovery OR until the the symptoms or oral mucositis resolve, whichever occurs last. Patients will also complete a study diary to record symptoms of oral mucositis.

Group Type: EXPERIMENTAL

Caphosol

Intervention Type: DRUG

Subjects randomized to the Caphosol Arm will use Caphosol 4 times per day as follows:

• Each dose consists of two 15 mL syringes, to be mixed at time of administration. Caphosol must be used within 15 minutes of mixing.

o Participants may increase the use to 6 times per day if you have symptoms of mucositis.

• Using one of the syringes, rinse and gargle (if patient is able) for one minute and then spit. Repeat using the remaining syringe.

• For younger patients (less than or equal to 6 years of age), volume may be reduced to two syringes containing 5-10 mL each.
• For patients unable to successfully rinse and spit, caregivers may paint their mouth (using medical sponge swabs) with the solution two times. Repeat using the second syringe.
• Patients are to avoid other oral medications, other mouth cares and food or drink for 15 minutes after using Caphosol.
• Patients may use Biotene (5-10 mL) to swish and spit after the 15 minutes has passed

Control Arm

Control Arm: Subjects randomized to the Control Arm will use Biotene 4 times per day. They will also complete a study diary to record doses and any symptoms of oral mucositis. This will begin at the start of chemotherapy until for 7 days AND until ANC \>500 after nadir or oral mucositis resolves (whichever occurs later)

Group Type: ACTIVE_COMPARATOR

Biotene

Intervention Type: DRUG

• Use 5 to 10 mL of Biotene to swish and spit

o For patients unable to successfully rinse and spit, caregivers may paint their mouth (using medical sponge swabs) with the solution two times. Prior to swabbing the patient's mouth, pour Biotene into a cup and using the medical sponge, soak up the solution and use the swab to coat the inside of the patient's mouth. Repeat with a second swab.

Interventions

Caphosol

• Each dose consists of two 15 mL syringes, to be mixed at time of administration. Caphosol must be used within 15 minutes of mixing.

o Participants may increase the use to 6 times per day if you have symptoms of mucositis.

• Using one of the syringes, rinse and gargle (if patient is able) for one minute and then spit. Repeat using the remaining syringe.

• For younger patients (less than or equal to 6 years of age), volume may be reduced to two syringes containing 5-10 mL each.
• For patients unable to successfully rinse and spit, caregivers may paint their mouth (using medical sponge swabs) with the solution two times. Repeat using the second syringe.
• Patients are to avoid other oral medications, other mouth cares and food or drink for 15 minutes after using Caphosol.
• Patients may use Biotene (5-10 mL) to swish and spit after the 15 minutes has passed

Intervention Type: DRUG

Biotene

• Use 5 to 10 mL of Biotene to swish and spit

o For patients unable to successfully rinse and spit, caregivers may paint their mouth (using medical sponge swabs) with the solution two times. Prior to swabbing the patient's mouth, pour Biotene into a cup and using the medical sponge, soak up the solution and use the swab to coat the inside of the patient's mouth. Repeat with a second swab.
