Lovastatin in Reducing Side Effects After Radiation Therapy in Women With Breast Cancer

June 11, 2013 updated by: Virginia Commonwealth University

A Phase II Study Using Lovastatin to Improve Cosmetic Outcome After Radiation Therapy for Breast Cancer

RATIONALE: Drugs, such as lovastatin, may protect normal cells from the side effects of radiation therapy.

PURPOSE: This phase II trial is studying how well lovastatin works in reducing side effects after radiation therapy in women with breast cancer.

Study Overview

Detailed Description

OBJECTIVES:

  • To determine the incidence of good/excellent cosmetic outcome, as defined by the Harvard Scale, after radiotherapy in women treated with lovastatin, as compared to historical controls.

OUTLINE: Patients undergo standard external beam whole-breast irradiation and/or accelerated partial breast irradiation. Patients receive oral lovastatin once daily beginning on the first day of radiotherapy and continuing for 12 months in the absence of disease progression or unacceptable toxicity.

Patients complete a questionnaire, the Breast Cancer Treatment Outcome Scale, at baseline and then at 6 months, 12 months, and 3 years after completion of radiotherapy to assess cosmetic and functional outcomes.

After completion of radiotherapy, patients are followed periodically for up to 5 years.

    • Prior radiotherapy to the contralateral breast allowed
  • No chemotherapy for ≥ 2 weeks prior to, during, and for ≥ 2 weeks after completion of radiotherapy
  • No concurrent cytochrome P450 3A4 inhibitors
  • Concurrent HMG-coA-reductase inhibitor allowed provided patient is able to switch to 20 mg of lovastatin per day
  • Concurrent tamoxifen or an aromatase inhibitor allowed

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
EXPERIMENTAL: Supportive care (lovastatin)
Patients undergo 25-28 fractions of standard whole-breast irradiation followed by a boost to the tumor bed or 10 fractions of accelerated partial-breast irradiation with balloon brachytherapy BID over 5-10 days. Patients also receive lovastatin PO QD for 12 months beginning on day 1 of radiation therapy. Treatment continues in the absence of disease progression or unacceptable toxicity.
