Sorafenib in Treating Patients With Advanced Malignant Solid Tumors
Single Agent Sorafenib in Advanced Solid Tumors: Phase II Evaluation of Dose Re-Escalation Following a Dose Reduction (IST000375)
RATIONALE: Sorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor.
PURPOSE: This phase II trial is studying the side effects and best dose of sorafenib and to see how well it works in treating patients with advanced malignant solid tumors.

Intervention / Treatment
Detailed Description
OBJECTIVES:
Primary
- To evaluate the feasibility of re-escalating the dose of sorafenib tosylate in patients with advanced malignant solid tumors who initially required a dose reduction for toxicity, and dose escalation in those patients who are able to tolerate the initial dose.
Secondary
- To evaluate the efficacy of this drug in these patients who are able to tolerate a dose escalation initially or after a dose reduction compared to those who are unable to tolerate a dose escalation.
Tertiary
- To evaluate the percentage and demographic characteristics of patients who are able to tolerate 2 dose escalations without a dose reduction.
OUTLINE: This is a dose-finding study.
- Course 1: Patients receive oral sorafenib tosylate twice daily at dose level 0 on weeks 1-4.
- Course 2: Patients experiencing no dose-limiting or intolerable toxicities receive oral sorafenib tosylate at dose level +1 twice daily on weeks 5-8; while patients experiencing dose-limiting or intolerable toxicities receive oral sorafenib tosylate at dose level -1 once daily on weeks 5-8.
- Course 3: Depending on whether or not patients are experiencing dose-limiting or intolerable toxicities, they are escalated to dose level 0 or dose level +2 (patients in both dose levels receive oral sorafenib tosylate twice daily) in weeks 9-12, or de-escalated to dose level 0 or dose level -2 (patients in dose level -2 receives oral sorafenib tosylate once every other day) in weeks 9-12.
- Maintenance therapy: Patients receive oral sorafenib tosylate at the dose level* attained at the end of course 3. Treatment continues in the absence of unacceptable toxicity.
- Dose level de-escalation for toxicity or dose re-escalation after a toxicity-related dose reduction allowed to a maximum level of the initial dose level of the maintenance therapy.
After completion of study therapy, patients are followed for up to 1 year.

Intervention / Treatment |
---|---|
Experimental: Sorafenib
Dose Re-Escalation Following a Dose Reduction
|
Patients will be registered and started on the standard recommended dose-schedule for sorafenib (400 mg tablet by mouth twice a day continuously).
Dose reductions will be instituted in the event of grade 3 or higher hematologic or non-hematologic toxicity or for any toxicity that is considered by the patient or physician as intolerable.

Measure Description |
Time Frame |
---|---|---|
Percentage of Patients Tolerating Re-escalated Dose of Sorafenib for 28 Days Without Dose Interruption or De-escalation for Toxicity
Time Frame: At least 3 months
|
Overall percentage of patients tolerating a dose escalation to 600 mg twice daily for 28 days plus the percentage tolerating a re-escalation to 400 mg twice daily in Cycle 3.
|
At least 3 months
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Overall Response Rate
Time Frame: At least 3 months
|
Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR).
|
At least 3 months
|
Time to Disease Progression
Time Frame: Up to 2 years
|
Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.
|
Up to 2 years
