Clinical Trial Summary

This phase I trial is studying the side effects and best dose of sorafenib and bortezomib in treating patients with advanced cancer. Sorafenib and bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Sorafenib may also stop the growth of cancer cells by blocking blood flow to the cancer

Description:

OBJECTIVES:

I. To determine the maximum tolerated dose (MTD) of sorafenib and bortezomib in patients with advanced malignancies.

II. To describe the toxicities associated with the combination of sorafenib and bortezomib.

III. To evaluate the therapeutic antitumor activity of the combination of sorafenib and bortezomib.

IV. To evaluate the effects of sorafenib on the disposition of bortezomib.

OUTLINE: This is a dose-escalation study. Patients are assigned to 1 of 2 groups according to disease type.

GROUP I (solid tumors-dose-escalation group): Patients receive oral sorafenib twice daily on days 1-21 and bortezomib IV over 3-5 seconds on days 1, 4, 8, and 11. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of sorafenib and bortezomib until the MTD is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.

GROUP II (multiple myeloma or chronic lymphocytic leukemia-maximum tolerated dose [MTD] group): Patients receive oral sorafenib at the MTD twice daily on days 3-21 of course 1 and on days 1-21 of each subsequent course. Patients also receive bortezomib IV over 3-5 seconds at the MTD on days 1, 4, 8, and 11.

Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed for 3 months.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	MTD as assessed by the number of patients with dose-limiting toxicity (DLT) using Common Terminology Criteria for Adverse Events version 3.0 (CTCAE v3.0)	DLTs include: Hematologic: Grade 4 ANC for =5 days, Grade 4 anemia of any duration, or PLT <25,000 of any duration; Renal: Serum creatinine =2 times baseline or > 2x upper limit of normal if baseline levels normal; All other non-hematologic toxicities =grade 3 as per CTCAE v3.0 except fatigue; Any toxicities that caused dose delay of > 2 weeks of the intended next dose.; MTD is the dose level below the lowest dose that induces DLT in at least one-third of patients (2 of 6 patients).	Observed for at least 3 weeks at a given dose level combination	Yes
Primary	Toxicity as assessed by CTCAE v3.0	Non-hematologic toxicities will be evaluated via the ordinal CTC standard toxicity grading. Hematologic toxicity measures of thrombocytopenia, neutropenia, and leukopenia will be assessed using continuous variables as the outcome measures (primarily nadir) as well as categorization via Common Toxicity Criteria standard grading.; Overall toxicity incidence as well as toxicity profiles by dose level, patient and tumor site will be explored and summarized. Frequency distributions, graphical techniques and other descriptive measures will form the basis of these analyses.	Observed for at least 3 weeks at a given dose level combination	Yes
Primary	Antitumor activity as assessed by tumor measurement or evaluation of indicator lesion by computed tomography (CT) or magnetic resonance imaging (MRI)		Baseline, prior to each course (every 3 weeks) during dose escalation, every 6 weeks for solid tumors, and confirmatory scans at least 4 weeks following initial documentation of objective response	No
Primary	Effects of sorafenib on the disposition of bortezomib	Up to 20 patients with hematologic malignancies will be treated at the MTD to evaluate markers of drug activity and pharmacokinetics of this combination.	From cohort II registration prior to each course	No
Secondary	Tumor response as assessed by CT or MRI using modified Response Evaluation Criteria in Solid Tumors (RECIST)	CLL Modified RECIST: Measurable lesions: lesions that can be accurately measured in at least one dimension with longest diameter > 20 mm. With spiral CT scan, lesion must be > 10 mm in at least one dimension. Target lesions (up to 3) should be selected and a sum of the longest diameter (LD) for all will be the baseline sum LD. Complete Response (CR): Disappearance of all target lesions Partial Response (PR): At least 30% decrease in the sum of the longest diameter (LD) of target lesion taking as reference the baseline sum LD.	Baseline, every 3 weeks during dose escalation, every 6 weeks for solid tumors, and confirmatory scans at least 4 weeks following initial documentation of objective response	No
Secondary	Best overall response as assessed using modified RECIST	CLL Progression (PD): As least a 20% increase in the sum of LD of target lesions taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions.	Baseline until disease progression/recurrence	No
Secondary	Duration of overall response	Myeloma CR = Disappearance of M-protein from serum and urine, Bone marrow biopsy =5% plasma cells, No increase in lytic bone lesions, and Disappearance of soft tissue plasmacytomas. Patients who meet some, but not all, the criteria are classified as VGPR. Myeloma PR = 50-89% reduction of M-protein in serum and reduction of =90% or to <200 mg in 24-hour urinary light chain excretion (patients with non-secretory myeloma: a =50% reduction in plasma cells in a bone marrow aspirate), =50% reduction in soft tissue plasmacytoma, and No increase in number or size of lytic bone lesions.	From the time measurement criteria are met for CR/PR (whichever is first recorded) until the first date recurrent or progressive disease is documented	No
Secondary	Duration of stable disease	Myeloma PD: Increase of M-protein >25% above the lowest response level in serum or urine (absolute increase of at least 0.5 g/dL serum or 200 mg/24 hours urine); Patients with non-secretory myeloma: an increase in bone marrow plasmacytosis by 25% above the lowest remission value (absolute increase at least 10% bone marrow plasma cells); New soft tissue plasmacytomas or increase in size by 50% (and at least 1 cm); New lytic bone lesions or increase in the size of the existing bone lesions by 50% (and at least 1 cm); Development of hypercalcemia serum calcium >11.5 mg/dL.	From the start of the treatment until the criteria for progression are met	No
