Colorectal Cancer | Bovine Lactoferrin in Reducing Taste Disturbances in Patients With Colorectal Cancer Receiving Oxaliplatin-Based Chemotherapy

Colorectal Cancer research study

What is the primary objective of this study?

The purpose of this research study is to determine if using a lactoferrin supplement will improve taste perception. Lactoferrin is a type of protein that is naturally produced in the body and is commonly found in saliva.

Who is eligible to participate?

Inclusion Criteria: - Patients must have histologically or cytologically confirmed colorectal carcinoma - There are no restrictions on the amount or types of prior therapy - Eligible patients must be receiving ongoing chemotherapy with an oxaliplatin containing-regimen which is planned to continue for at least one month following enrollment in this trial - Any dose or schedule of oxaliplatin administration is allowed as long as patients have self-reported taste disturbance that has either: - 1) developed since the initiation of oxaliplatin-based therapy, or - 2) a pre-existing, treatment-induced taste disturbance has subjectively worsened since initiating oxaliplatin-based therapy - Patients must have normal baseline self-reported taste perception prior to the development of colorectal carcinoma - Life expectancy of >= 3 months - Ability to understand and the willingness to sign a written informed consent document Exclusion Criteria: - Patients with a subjective history of an extreme dry mouth syndrome that prevents them from producing adequate amounts of saliva (approximately 2 mL in 15-20 min) - Patients known to be human immunodeficiency virus (HIV)-positive - Patients with any of the following conditions: untreated gastrointestinal reflux disease; untreated diabetes mellitus; active thrush; active oral infection; active mucositis - Patients who are known to be pregnant or who are breastfeeding are excluded

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.

Supportive care (bovine lactoferrin)Patients receive bovine lactoferrin PO (rinse or tablet) TID for 1 month. Treatment continues in the absence of unacceptable toxicity.
