Clinical Trial Summary

Investigators are hoping to learn if glucosamine with chondroitin can help relieve joint pain/stiffness associated with aromatase inhibitors.

Description:

Due to early detection and improved treatments, women with breast cancer are living longer. The increase in breast cancer survival is largely due to the benefits of hormonal therapy, such as tamoxifen and aromatase inhibitors (AIs), for the treatment of hormone-sensitive breast cancer. Recent clinical trials have demonstrated that AIs are more effective than tamoxifen at reducing breast cancer recurrences. However, breast cancer patients receiving AIs have a higher incidence of osteoporosis, bone fractures and musculoskeletal symptoms, particularly joint pain and stiffness. Musculoskeletal pain, which occurs in up to 50% of patients treated with AIs, often does not respond to conventional pain medications, may lead to noncompliance, may cause major disability, and may interfere with quality of life. Many women are unable to tolerate these life-saving drugs because of severe joint pain, therefore, safe and effective treatments that alleviate these symptoms are needed.

Recruitment information / eligibility

• Status: Completed
• Enrollment: 53
• Est. completion date: September 2012
• Est. primary completion date: July 2012
• Accepts healthy volunteers: No
• Gender: Female
• Age group: 21 Years and older

Eligibility

Inclusion Criteria:

• Age >21 years.
• Postmenopausal status defined as cessation of menses for >1 year or follicle-stimulating hormone (FSH) >20 milli-international units per milliliter or bilateral oophorectomy.
• History of stage I, II or III hormone receptor-positive breast cancer, without metastatic disease.
• Currently taking a third-generation aromatase inhibitor for at least 3 months.
• Clinical symptoms of knee and/or hand joint pain and/or stiffness for at least 3 months prior to study entry.
• Ongoing musculoskeletal pain/stiffness in hand and/or knee joints (50 or higher on the 100 point global assessment VAS) that started or increased since initiating aromatase inhibitor therapy, and has been present for at least 3 months.
• Patients must agree to refrain from use of glucosamine and chondroitin from sources outside of this study.
• If taking bisphosphonates, on a stable dose for at least 3 months and tolerating the dose. Patients must agree to refrain from initiating bisphosphonate use during the course of the study, therefore it is recommended that routine bone density testing be performed prior to enrollment or after completing trial.
• Eastern Cooperative Oncology Group (ECOG) performance status 0-2.
• Hemoglobin A1c <8 within the last year.
• Signed informed consent.

Exclusion Criteria:

• Use of glucosamine or chondroitin within the past three (3) months.
• Concurrent medical/arthritic disease that could confound or interfere with evaluation of pain or efficacy.
• History of significant collateral ligament, anterior cruciate ligament or meniscal injury of the index joint requiring surgery or non-weight bearing (requiring use of crutches or cane) for more than 3 weeks (minor ligamentous injury prior to 6 months is not an exclusion).
• History of bone fracture or surgery of the afflicted knees and/or hands within 6 months prior to study entry.
• Uncontrolled diabetes mellitus, defined as Hemoglobin A1c level of > 8%.
• History of any illness that, in the opinion of the investigator, might confound the results of the study or pose additional risk to the patient.
• Allergy to, or history of significant clinical or laboratory adverse experience associated with acetaminophen, glucosamine or chondroitin sulfate.
• Allergy to shellfish.
• Inability to understand and complete study questionnaires including questions requiring a visual analog scale (VAS) response.
• Inability to understand the study procedures and/or give written informed consent.
• Alcohol use in excess of 3 mixed drinks/day.
• Corticosteroid treatment was used or administered.
• Aspirin (up to 325 mg/day) for cardiovascular reasons may be continued.
• Intra-articular injection of hyaluronic acid or congeners into the study joint within 12 months.
• Topical analgesics (e.g., capsaicin preparations) to the study joint, or any oral analgesics (e.g., opiates, tramadol; with the exception of ibuprofen and acetaminophen) within 2 weeks of baseline visit or during the study.
• Implementation of any other medical therapy for arthritis within one month prior to entry.
• Other medications, unrelated to the patient's joint pain/stiffness must have been used at a stable dosage for at least 1 month. In addition, it should be anticipated that the dose of the concomitant medication will be stable during the entire treatment period.
• Participation in another clinical study with an investigational agent within the last 4 weeks.
• Exposure to glucosamine within 3 months or chondroitin sulfate within 3 months of Baseline Visit.
• Initiation of physical therapy or muscle conditioning program within 2 months prior to study entry.
• Concurrent use of the following medications and dietary supplements.
• Chronic therapy with tetracycline or tetracycline derivatives.
• Other new complementary or alternative regimens for the treatment of osteoarthritis, including, but not limited to, acupuncture, topical creams, oral agents, and magnets.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in WOMAC Score	This is to demonstrate improvement in knee and/or joint pain and/or stiffness. The Western Ontario and McMaster Universities Arthritis Index (WOMAC) is widely used in the evaluation of Hip and Knee Osteoarthritis. It is a self-administered questionnaire consisting of 24 items divided into 3 subscales. The scores for each subscale are summed up, with a possible score range of 0-20 for Pain, 0-8 for Stiffness, and 0-68 for Physical Function. The test questions are scored on a scale of 0-4, which correspond to: None (0), Mild (1), Moderate (2), Severe (3), and Extreme (4). The sum of the scores for all three subscales gives a total WOMAC score which ranges from 0-96. Higher scores on the WOMAC indicate worse pain, stiffness, and functional limitations.
