Trial Comparing Trabectedin to the Best Supportive Care in Patients With Sarcoma

• Status: Completed
• Trial end date: 2018-07-14
• Target enrollment: 0
• Participant gender: All

Summary

As the transparency committee of the Haute Autorité de Santé pointed out due to lack of data regarding comparative trial of Yondelis versus best supportive care, activity of Yondelis in soft tissue sarcoma remain to be assessed.

For an antineoplastic drug toxicity is moderate. As previous studies shown, overall survival data for patients with advanced or metastatic STS are of poor prognosis despite improvement of results this last years. For example, median overall survival increased from 12,3 months (1987-1991) to 11,4 months (1992-1996) and then 18 months (2002-2006).

Considering the latest results with and without Trabectedin, the investigators may consider that comparing Trabectedin with best supportive care is ethically acceptable as long as patients consent to enter the trial.

• Alkaline phosphatases ≤ 2.5 UNL,

• bilirubin ≤ UNL ,

• CPK ≤ 2.5 times the investigator laboratory UNL,

• albumin ≥ 25 g/L

• creatinine clearance measured or calculated (Cockcroft-Gault formula) ≥ 30 mL/min.

2. History of allergic reaction or known hypersensitivity to dexamethasone or to anti-emetic agents belonging to the triptan family (i.e., 5-HT3 receptor antagonists).

3. History of allergic reaction or known hypersensitivity to contrast agents (except if the patient's tumour can be evaluated using MRI without contrast agents).

4. Severe concomitant disease (such as pulmonary fibrosis, interstitial pneumonitis, renal insufficiency, liver failure, cerebrovascular disease, malignant disease requiring blood transfusions, or uncontrolled diabetes).

5. Clinically significant abnormalities of the electrocardiogram test, or one of the following clinically significant cardiac diseases :

• Myocardial infarction within one year prior to study entry.

6. Surgery under general anaesthesia within 28 days prior to study entry, exploratory surgery (thoracotomy or laparotomy) within 28 days prior to study entry,.
