Brief Summary:
This is a single-center, phase 2 randomized clinical trial of tamoxifen on mean percent predicted isometric muscle strength in patients with amyotrophic lateral sclerosis (ALS). The purpose is to determine whether the triphenylethylenetamoxifen, used as adjuvant therapy in the treatment of breast cancer, can delay the loss of isometric muscle strength in ALS patients.

Official Title: Phase 2 Randomized Single-blind Escalating Dose Response Clinical Trial of Tamoxifen Therapy on Mean Percent Predicted Isometric Strength in Amyotrophic Lateral Sclerosis [ALS]
Study Start Date : January 2001
Actual Study Completion Date : January 2005

Primary Outcome Measures :
  1. Stability at 6, 12, 18 and 24 months on of the patient's mean percent predicted arm strength

Secondary Outcome Measures :
  1. Vital capacity, raw liters and percent predicted, compared with baseline measured at 3 month intervals.
  2. Individual arm and leg muscle mean percent predicted isometric strength compared with baseline measured at 3 month intervals.
  3. Bulbar, Breathing, arm and leg subscores of ALS Functional Rating Scale - Revised [ALS-FRS-R] compared with baseline measured at 3 month intervals.
  4. Total ALS Functional Rating Scale [ALS-FRS-R] compared with baseline measured at 3 month intervals.
