Study to Assess Effect of 8 Wks of Duloxetine Therapy on Breast Cancer Patients With Aromatase-Inhibitor Associated Pain
Completed · Not applicable
Conditions studied: Breast Cancer
In brief
Many women with breast cancer who are treated with aromatase inhibitor medications develop aches and pains during treatment, and some develop numbness and tingling in their hands and feet. Some examples of aromatase inhibitor medications include anastrozole (Arimidex), exemestane (Aromasin), and letrozole (Femara). Frequently, pain medications do not work very well to relieve the pain. Duloxetine (Cymbalta) is a medication that was originally developed to treat depression. It has also been found to relieve pain that occurs in people with diabetes, fibromyalgia, arthritis, and other painful conditions. In this study we are testing to see if duloxetine will help treat the pain that can occur in women treated with aromatase inhibitors.

Who can join
Age: 21 and older. Sex: female. Healthy volunteers: not accepted.
You may qualify if…
- Female;
- Histologically proven stage 0-III invasive carcinoma of the breast that is ER and/or PR positive by immunohistochemical staining, who are receiving a standard dose of aromatase inhibitor (AI) therapy (letrozole 2.5mg once daily or exemestane 25mg once daily or anastrozole 1mg once daily). Women with oligometastatic disease may be included at the discretion of the principal investigator. Surgical resection, chemotherapy, and radiation therapy must have been completed at the time of study enrollment, with the exception of trastuzumab;
- AI therapy has been ongoing for ≥ 2 weeks and treatment is expected to continue;
- AI-associated musculoskeletal symptoms, defined as:
- Grade 1 or higher musculoskeletal pain that developed or worsened (6 or 7 on CGICS) during AI therapy or
- Grade 1 or higher sensory neuropathy that developed or worsened (6 or 7 on CGICS) during AI therapy;
- Average pain of ≥4 on the 11-point Likert scale of question #5 of the Brief Pain Inventory;
- ECOG performance status 0-2;
- Willing and able to sign an informed consent document.
You may not qualify if…
- Known hypersensitivity to duloxetine or any of the inactive ingredients;
- New musculoskeletal pain that is due specifically to fracture or traumatic injury;
- Treatment with monoamine oxidase inhibitors (MAO-I) within 14 days of enrollment;
- Concurrent treatment with phenothiazines (including thioridazine), propafenone, flecainide, triptans, MAO-Is, SSRIs, SNRIs, or tricyclic antidepressants;
- Currently primary psychiatric diagnosis (schizophrenia, psychosis) or suicidal ideation, history of bipolar disorder, or seizure disorder;
- Chronic liver disease, end stage renal disease, or creatinine clearance < 30 mL/min as defined by the Cockroft-Gault equation;
- Uncontrolled narrow-angle glaucoma or clinically significant coagulation disorder;
- Pregnant or breast feeding;
- History of alcohol or other substance abuse or dependence within the year prior to enrollment;
