Phase II Study of Regorafenib as Maintenance Therapy
Study Details
Study Description
Brief Summary
Multicenter double-blind placebo-controlled randomized Phase II study comparing regorafenib® to placebo, as maintenance therapy in metastatic soft-tissue non-adipocytic sarcomas experiencing stable disease or response after 6 cycles of doxorubicin-based chemotherapy as 1st line chemotherapy.
| Condition or Disease | Intervention/Treatment | Phase |
|---|---|---|
|
Phase 2 |
Detailed Description
Patients will be randomized 1:1 using a centralized randomization software, assuring concealment, with a minimization program controlling for the following factors:
-
Histological subgroups: leiomyosarcoma versus synovial sarcoma versus other histological subtype
-
Response to doxorubicin-based chemotherapy: partial response versus stable disease
-
Centers
The treatment will be administrated as long as it appears beneficial. Evaluations will be made every 8 weeks until 6 months and then every 3 months
Study Design
Arms and Interventions

| Experimental: Arm A Regorafenib |
Drug: Regorafenib
Oral Drug in the form of 40 mg tablets - Regorafenib (120 mg/d) once daily for 3 weeks on / 1 week off plus Best Supportive Care (BSC) until progression (according to RECIST 1.1), intolerance or consent withdrawal.
Provided by BAYER
Other Names:
|
| Placebo Comparator: Arm B Placebo |
Drug: Placebo
Oral tablets - Placebo plus BSC until progression (according to RECIST 1.1) or unacceptable toxicity. Patients who have received placebo may be offered open-label regorafenib (cross-over option) after objective tumor progression

Outcome Measures
Primary Outcome Measures
- To assess the efficacy of regorafenib compared to placebo [from the date of randomization to the date of first observed disease progression (according to RECIST 1.1 criteria) or death from any cause, up to 12 months after the beginning of the treatment]
Progression-Free Survival will be measured from the date of randomization until the date of radiological progression (according to RECIST 1.1 criteria) or death (if death occurs before progression).
Secondary Outcome Measures
- To assess the efficacy of regorafenib compared to placebo [from the date of randomization to the date of death from any cause]
in terms of overall survival
- To assess the efficacy of regorafenib compared to placebo [from the date of randomization to the date of first observed disease progression (according to RECIST 1.1) or death from any cause, up to 12 months after the beginning of the treatment]
Best response according to RECIST 1.1 evaluated by central radiological review: Complete Response, CR, or Partial Response, PR, achieved during the maintenance therapy. CR and PR will be counted as objective response to estimate the objective response rate (ORR)
- To assess the efficacy of regorafenib compared to placebo [from the date of randomization to the date of death from any cause, up to 12 months after the beginning of the treatment]
Time to start subsequent line of anticancer therapy defined as the time interval from the date of randomization to the date of start subsequent line of anticancer therapy. Patient data will be censored at the date of last follow-up visit for patients alive at last follow-up visit without having started subsequent line of anticancer therapy. Death without having started subsequent line of anticancer therapy will be counted as a competing event.
- To assess the safety of regorafenib [Baseline, every 4 weeks, up to 12 months after the beginning of the treatment]
Compared to placebo - Toxicity according to NCI-CTC AE V5.0 over the whole treatment duration plus 30 days, excluding AE unequivocally related to the disease under study or its progression. Adverse events of grade 3 or more (grade 3+) will be counted as severe adverse events
- To assess the relative benefit/risk ratio [up to 12 months]
using the Q-TWiST approach - Quality-adjusted time without symptoms of disease or toxicity computed from survival times (overall survival and progression-free survival) and adverse events data (date of occurrence of grade 3+ adverse event classified as drug-related)
Other Outcome Measures
- assessment of the predictive value of SUMSCAN signature [up to 12 months]
genomic signature established on initial diagnostic biopsies or resection specimen and identifying sarcoma patients benefitting from anti-angiogenetic agents
