Details and patient eligibility

About

The purpose of the assay is to assess the safety and the efficacy of TRO19622 330 mg QD as add-on therapy to riluzole 50 mg bid in the treatment of patients suffering from ALS, as compared to placebo, assessed by the 18-month survival rate.

Full description

A stand alone treatment with TRO19622 is not acceptable for ethical reasons. Riluzole is an approved and widely used ALS treatment in the European community, in Japan and in the USA.

Therefore, in this study, TRO19622 will be assessed as add-on to riluzole in patients suffering from ALS.

At the start of the study, patients will be randomized to one of two groups : TRO19622 (330 mg QD or placebo (once a day).

Each treatment will be administered for 18 months under double-blind conditions. The product under evaluation will be administered to patients receiving the standard of care for ALS, including riluzole.

Riluzole dosage (50 mg bid) must be stable and well tolerated for at least one month prior to inclusion into the study.

After the double-blind period, open-label administration of TRO19622 will be allowed for safety and survival assessments and until efficacy results are available.

A separate open-label protocol will be written 6 months after the randomization of the last patient into the study.

Enrollment: 512 patients

Sex: All

Ages: 18 to 80 years old

Volunteers: No Healthy Volunteers

• Be of age >18 (exclusive) and < 80 years (inclusive).
• If a female, not lactating, has a negative pregnancy test and agrees to use an effective method of birth control.
• Onset of ALS Symptoms (weakness) for more than 6 months (inclusive) and less than 36 months(inclusive).
• Slow vital capacity (SVC), measured three times, one of the measure being >/= 70% of that predicted.
• Treated with riluzole at the stable dose of 50 mg bid for at least 30 days before enrolment.

Exclusion criteria

• Tracheostomy, invasive ventilation, or non invasive positive pressure ventilation (NIPPV).

• Gastrostomy.

• Evidence of major psychiatric disorder or clinically evident dementia.

• Diagnosis of a neurodegenerative disease in addition to ALS.

• Have a current medication that could interfere with TRO19622 pharmacokinetics: tamoxifene.

• Have current medications that could interfere with TRO19622 absorption such as ezetimibe, bile salts chelators (cholesteramine), fibrates, phytosterols, niacin (vitamin B3),fish oils. Have a current medication of lipid lowering agents other than statins.

• Known hypersensitivity to any component of the study drug.

• Patients with known intolerance or contra-indication to riluzole.

• Have a recent history (within the previous 6 months) or current evidence of alcohol or drug abuse.

• Have concurrent unstable disease involving any system eg, carcinoma other than basal cell carcinoma, any cardiac dysrhythmia, myocardial infarction, clinical or ECG signs of myocardial ischemia, cardiac insufficiency, angina symptoms, current symptoms of Coronary Artery Disease, or any other condition that in the opinion of the Investigator would make the patient unsuitable for study participation.

  . In Germany: Have any cardiac dysrhythmia, myocardial infarction, clinical or ECG signs of myocardial ischemia, cardiac insufficiency, angina symptoms, current symptoms of Coronary Artery Disease or any cardiovascular illness known or identified at the screening or inclusion visits, or have concurrent unstable disease involving any system eg, carcinoma other than basal cell carcinoma or any other condition that in the opinion of the Investigator would make the patient unsuitable for study participation.
