Toremifene in Desmoid Tumor: Prospective Clinical Trial and Identification of Potential Molecular Targets
Study Details
Study Description
Brief Summary
This is a prospective study evaluating the activity and the safety of toremifene in patients with primary or recurrent sporadic DTs.
Patients will be enrolled after the histological confirmation of DTs on biopsy Patients will start at 60 mg daily and dose-escalate to 180 mg upon progression. Disease assessment will be performed by contrast-enhanced MRI or CT scan, pain evaluation by a visual analog scale (VAS) every 3 months for the first and second year, twice yearly thereafter. Response will be evaluated either by RECIST and/or symptomatic relief.

Detailed Description
This is a prospective study evaluating the activity and the safety of toremifene in patients with primary or recurrent sporadic DTs.
Patients will be enrolled after the histological confirmation of DTs on biopsy performed at the investigators institution or after the pathological review of tissue specimen obtained via needle biopsy or surgical excision (in case of recurrence) performed elsewhere. A new biopsy will be performed if the amount of tissue will not be sufficient for immunohistochemical analysis. Patients will start at 60 mg daily and dose-escalate to 180 mg upon progression. Disease assessment will be performed by contrast-enhanced MRI or CT scan, pain evaluation by a visual analog scale (VAS) every 3 months for the first and second year, twice yearly thereafter. Response will be evaluated either by RECIST and/or symptomatic relief.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Toremifene treatment Patients will receive 60 mg daily of Toremifene and the dose will be escalated to 180 mg daily in case of progression |
Drug: Toremifene
Patients will receive 60 mg daily and then 180 daily in case of progression

Outcome Measures
Primary Outcome Measures
- Time to progression [2 years]
This study evaluates clinical benefit by comparing sequentially measured paired failure times within each treated patient, namely time to progression after the 60 mg toremifene dose (TTP1) versus the (possibly censored) time to progression after the 180 mg toremifene dose (TTP2)
Eligibility Criteria
Criteria
Inclusion Criteria:
