Caphosol Study

Details and patient eligibility

About

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.

Full 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.

Enrollment: 1 patient

Volunteers: No Healthy Volunteers

Inclusion criteria

• Oncology patients, at initiation of their oncology therapy, who are at risk of developing oral mucositis during their scheduled cancer therapy, defined by meeting one or more of the following criteria:

• Patients receiving one or more of the following chemotherapy agents:

  • Actinomycin D
  • Carboplatin
  • Cisplatin
  • Cytarabine at doses > 1 gram/m2
  • Daunorubicin
  • Doxorubicin
  • Methotrexate at doses > 1 gram/m2
  • Mitoxantrone

• Age 0 to 25 years

• Voluntary written consent before performance of any study-related procedure not part of normal medical care, with the understanding that consent may be withdrawn by the subject at any time without prejudice to future medical care

Exclusion criteria

• Patients receiving glutamine treatment for oral mucositis.
• Patients undergoing autologous or allogeneic hematopoietic cell transplantation are excluded from this study.
• Patients receiving concurrent Head & Neck radiation therapy or within 6 weeks of completion of radiation therapy.
• Pregnant or lactating patients. The agent used in this study is not known to be teratogenic to a fetus, but has not been studies, and there is no information on the excretion of the agent into breast milk. All females of childbearing potential must have a blood test or urine study within 2 weeks prior to registration to rule out pregnancy.
• Known allergy to Caphosol

1 participants in 2 patient groups

Caphosol Arm

Experimental group

Description:

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.

Treatment:

Drug: Caphosol

Control Arm

Active Comparator group

Description:

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)

Treatment:

Drug: Biotene
