About this study

Official title: Phase 2 Selection Trial of High Dosage Creatine and Two Dosages of Tamoxifen in Amyotrophic Lateral Sclerosis (ALS)

The purpose of the study is to evaluate the safety and efficacy of high dose creatine and two dosages of tamoxifen treatment in amyotrophic lateral sclerosis (ALS).

Read the detailed description

Amyotrophic lateral sclerosis (ALS) is a rare, neurodegenerative disorder that results in progressive wasting and paralysis of voluntary muscles. It is known that nerve cells called motor neurons die in the brains and spinal cords of people with amyotrophic lateral sclerosis (ALS). However, the cause of this cell death is unknown.

In this double blind, randomized, selection design trial, researchers will evaluate the safety and effectiveness of creatine and tamoxifen in volunteers with ALS. There are a large number of potential drugs that may improve the survival or slow down the disease progression in people with ALS. The current strategy is to test one drug at a time against placebo. "Selection Design" is a different type of study design. A Selection Design study uses multiple drugs to screen against each other and picks the winner to take to a larger study. This design can speed the search for effective drugs to treat ALS. In this Selection Design study, each volunteer will take one active study drug (creatine 30gm, tamoxifen 40mg, or tamoxifen 80mg) and one placebo.

Approximately 60 eligible volunteers with ALS will be recruited from multiple centers in the US that belong to the Northeast ALS Consortium (NEALS). Volunteers will be randomly assigned equally to the three treatment arms: creatine 30gm/day, tamoxifen 40mg/day and tamoxifen 80mg/day. Volunteers will take study treatment for 38 weeks. After screening and randomization, volunteers will be followed at weeks 4, 10, 18, 28 and week 38. A final telephone interview will occur at week 42 (off study drug).

    creatine monohydrate powder

  • tamoxifenDrug

    Also called Nolvadex, Istubal, Valodex

    Tamoxifen citrate capsules

Study groups in NCT01257581
Study groupRoleWhat they receive
Creatine 30gmExperimentalCreatine will be taken as a powder mixed into food or liquid twice a day. Volunteers in this arm will take a total of 30gm of creatine per day for 38 weeks. Volunteers will also take placebo capsules twice a day for 38 weeks. This is a blinded study, so neither participants nor study staff will know which treatment a volunteer is receiving. Creatine is a nutritional supplement and is not approved by the U.S. Food and Drug Administration (FDA) for treating ALS.
Receives: Drug: creatine
Tamoxifen 40mgExperimentalTamoxifen will be taken as capsules twice a day. Volunteers in this arm will take a total of 40mg of tamoxifen per day for 38 weeks. Volunteers will also take placebo powder twice a day for 38 weeks. This is a blinded study, so neither participants nor study staff will know which treatment a volunteer is receiving. Tamoxifen is approved by the U.S. Food and Drug Administration (FDA) for breast cancer treatment but is not approved for treating ALS.
Receives: Drug: tamoxifen
Tamoxifen 80mgExperimentalTamoxifen will be taken as capsules twice a day. Volunteers in this arm will take a total of 80mg of tamoxifen per day for 38 weeks. Volunteers will also take placebo powder twice a day for 38 weeks. This is a blinded study, so neither participants nor study staff will know which treatment a volunteer is receiving. Tamoxifen is approved by the U.S. Food and Drug Administration (FDA) for breast cancer treatment but is not approved for treating ALS.
Receives: Drug: tamoxifen

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in ALS Functional Rating Scale - Revised (ALSFRS-R)

    Primary efficacy will be assessed by analyzing the mean rate of decline in the ALS Functional Rating Scale-Revised (ALSFRS-R) score over nine months. The ALSFRS-R is a quickly administered (5 min) ordinal rating scale used to determine a subject's assessment of their capability and independence in 12 functional activities. There are 12 questions, graded by the subject 0-4 (4 is normal). Score of 0 (worst) to 48 (best). Reflects speech and swallowing, fine motor skills, large motor skills, and breathing.

    Measured: 38 weeks of treatment followed by a telephone interview at 42 weeks.

Secondary outcomes (10)
  1. Vital Capacity/Pulmonary Function Testing

    Secondary efficacy will be assessed by analyzing the change in the Slow Vital Capacity score over nine months. Vital Capacity is the maximum amount of air a person can expel from the lungs after a maximum inhalation. A subject's VC depends on their age, sex and height. The value is recorded as a percentage of predicted normal.

    Measured: 38 weeks of treatment followed by a telephone interview at 42 weeks.

  2. Tracheostomy-free Survival

    Secondary efficacy will be assessed by analyzing rate of tracheostomy-free survival at nine months.

    Measured: 38 weeks of treatment followed by a telephone interview at 42 weeks.

  3. Dose Adjustments

    These events were due to a double-blinded study design.

    Measured: 38 weeks of treatment followed by a telephone interview at 42 weeks.

  4. Lab Abnormal Reports by Treatment Assignment

    The safety data is summarized according to treatment arm. Total number of Adverse Events (AEs), AEs that cause study drug withdrawal and abnormal laboratory tests are compared among treatment arms. A lab abnormality was a result that was out of range and considered clinically significant by the site investigator.

    Measured: 38 weeks of treatment followed by a telephone interview at 42 weeks.

  5. Hand Held Dynamometry (HHD) Lower Z-score

    The HHD lower z-scores are means of z-scores for right and left knee extension, knee flexion, hip flexion, and ankle dorsiflexion with z-scores calculated relative to the baseline mean and standard deviation strength of each muscle group across all participants.

    Measured: 38 weeks of treatment followed by a telephone interview at 42 weeks.

  6. HHD Lower % Baseline

    HHD % baseline measures are mean percent change for right and left knee extension, knee flexion, hip flexion, and ankle dorsiflexion from each participant's baseline.

    Measured: 38 weeks of treatment followed by a telephone interview at 42 weeks.

  7. HHD Upper Z-score

    The HHD upper z-scores are means of z-scores for right and left shoulder flexion, elbow extension, elbow flexion, write extension and first dorsal interosseous muscles with z-scores calculated relative to the baseline mean and standard deviation strength of each muscle group across all participants.

    Measured: 38 weeks of treatment followed by a telephone interview at 42 weeks.

  8. HHD Upper % Baseline

    The HHD % baseline measures are mean percent change for shoulder flexion, elbow extension, elbow flexion, wrist extension, and first dorsal interosseous muscles from each participant's baseline.

    Measured: 38 weeks of treatment followed by a telephone interview at 42 weeks.

  9. Accurate Test of Limb Isometric Strength (ATLIS) Lower Percentage of Predicted Normal (PPN)

    The ATLIS PPN measures are percentages of predicted normal strength based on age, gender, height, and weight using normative data.

    Measured: 38 weeks of treatment followed by a telephone interview at 42 weeks.

  10. ATLIS Upper Percentage of Predicted Normal (PPN)

    The ATLIS PPN measures are percentages of predicted normal strength based on age, gender, height, and weight using normative data.

    Measured: 38 weeks of treatment followed by a telephone interview at 42 weeks.
