S0528 Lapatinib and Everolimus in Treating Patients With Advanced Solid Tumors or Non-Hodgkin's Lymphoma

Lymphoma Clinical Trial

Official title: Phase I Study Evaluating the Combination of Lapatinib (GW572016; NSC-727989) and Everolimus (RAD001) in Patients With Advanced Solid Tumors

Status Completed

Clinical Trial Summary

RATIONALE: Lapatinib and everolimus may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Everolimus may also stop the growth of cancer cells by blocking blood flow to the cancer. Giving lapatinib together with everolimus may kill more cancer cells.

PURPOSE: This phase I trial is studying the side effects and best dose of lapatinib and everolimus in treating patients with advanced solid tumors or non-Hodgkin's lymphoma.

Clinical Trial Description

OBJECTIVES:

• Estimate the maximum tolerated dose (MTD) of lapatinib and everolimus in patients with advanced solid tumors or non-Hodgkin's lymphoma. (Part I)

• Investigate the pharmacokinetics of everolimus and lapatinib (when given alone and in combination) at the MTD determined in Part I. (Part II)

• Investigate the effects of everolimus and lapatinib (when given alone and in combination) on serum levels of vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), matrix metalloproteinase (MMP)-2 and MMP-9, interleukin-6 (IL-6), and tumor necrosis factor alpha (TNF-α). (Part II)

OUTLINE: This is a multicenter, dose-escalation study followed by a randomized study. Initial patients enrolled on the study are treated in part I. After the maximum tolerated dose (MTD) is determined in part I, subsequent patients are enrolled and treated in part II.

• Part I: Patients receive oral everolimus and oral lapatinib once daily on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of everolimus and lapatinib until the MTD is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity.

• Part II: Patients are randomized to 1 of 2 treatment arms. Everolimus and lapatinib are administered at the MTD determined in part I.

• Arm I: Patients receive oral everolimus once daily on days 1-28. Patients also receive oral lapatinib once daily on days 8-28 during the first course and on days 1-28 during all subsequent courses. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

• Arm II: Patients receive oral lapatinib once daily on days 1-28. Patients also receive oral everolimus once daily on days 8-28 during the first course and on days 1-28 during all subsequent courses. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Patients in part II undergo blood collection periodically for correlative biomarker and pharmacokinetic studies.

After finishing treatment, patients are followed periodically for 28 days.

PROJECTED ACCRUAL: A total of 48 patients will be accrued for this study. ;
