Sorafenib in Treating Patients With Refractory Non-Small Cell Lung Cancer

RATIONALE: Preclinical studies indicate that sorafenib is a potent inhibitor of Raf kinase in vitro and in vivo, with significant dose-dependent, anti-tumor activity in four different human tumor types including colon, pancreatic, lung, and ovarian. This activity was cytostatic in nature and was maintained if dosing was continued. That is, tumor growth is suspended while the drug is administered but returns to baseline rates when the agent is withdrawn. Therefore, the optimal schedule will be an uninterrupted one. To assess the activity of sorafenib in a timely manner and with a meaningful interpretation, a randomized discontinuation design was adopted in the present trial, conducted in a population who were potentially sensitive to sorafenib.

PURPOSE: This randomized phase II trial is studying sorafenib to see how well it works compared to placebo in treating patients with refractory non-small cell lung cancer.

About this study

OBJECTIVES:

  • To determine the percent of patients maintaining stable disease or objective response two months after randomization with continued sorafenib treatment, compared to patients switched to placebo.
  • To determine progression-free survival, overall survival, and response rate.

OUTLINE: This is a randomized, double-blind, multicenter study. Patients are stratified according to number of prior chemotherapy regimens (2 vs more than 2) and prior epidermal growth factor receptor inhibitor treatment (yes vs no).

  • Induction: All patients receive oral sorafenib twice daily on days 1-28. Treatment continues for 2 courses in the absence of disease progression or unacceptable toxicity. Patients with stable disease proceed to randomization. Patients with responding disease continue to receive sorafenib for up to 1 year in the absence of disease progression.
  • Randomization: Patients are randomized to 1 of 2 treatment arms.
  • Arm I: Patients receive oral sorafenib twice daily for up to 1 year in the absence of disease progression or unacceptable toxicity.
  • Arm II: Patients receive oral placebo twice daily for up to 1 year in the absence of disease progression or unacceptable toxicity. Patients who develop disease progression within 1 year after randomization cross over to arm I.

Patients are followed every 3 months for 2 years and then every 6 months for 3 years.

PROJECTED ACCRUAL: A total of 311 patients will be accrued for this study within approximately 3 years.

Treatment and study plan

Sorafenib

Drug

Step 1 (induction): Sorafenib was giventwice daily for two cycles to all patients. Patients with progression (PD) discontinued treatment. Those who responded after two cycles continued treatment up to 1 year or until PD. With response after 1 year, patients were given the option to continue treatment until PD. Patients who were stable after the end of induction were then randomized onto Step 2 to either continue sorafenib or receive placebo.

Step 2 (randomization): Patients with stable disease after induction will be randomized in a double-blinded manner to placebo or sorafenib. If a patient has progressed, the arm will be unblinded. Patients on placebo with PD can then crossover to receive sorafenib; patients with PD on the sorafenib arm will be removed from the study.

Step 3 (crossover): If patients on placebo progressed within 1 year from randomization, they crossed over to the treatment arm and receive sorafenib for up to 1 year or until PD, unacceptable toxicity, or death.

Other names: Nexavar, BAY 43-9006

Placebo

Drug

Patients randomized to the placebo arm in step 2 continued receiving placebo until disease progression or one year from randomization. Placebo was given orally twice a day (BID).

Primary outcomes

  1. Number of Patients Maintaining Stable Disease or Objective Response 2 Months After Randomization

    Time frame: Two months after randomization

    Per RECIST Criteria (V1.0):

    Complete Response (CR): disappearance of all target lesions Partial Response (PR): >=30% decrease in the sum of the longest diameter of target lesions Progressive Disease (PD): >=20% increase in the sum of the longest diameters of target lesions, taking as reference the smallest sum of longest diameter recorded since randomization, or the appearance of new lesions Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD

Secondary outcomes

  1. Progression-free Survival

    Time frame: Assessed every 8 weeks while on treatment. After the end of treatment, assessed every 3 months for 2 years, then every 6 months for 3 years.

    Progression-free survival is defined as the duration from randomization to disease progression or death, whichever occurs first. Only randomized patients were included in this analysis.

  2. Overall Survival

    Time frame: Assessed every 8 weeks while on treatment. After the end of treatment, assessed every 3 months for 2 years, then every 6 months for 3 years

    Overall survival is defined as the duration from randomization to death or last known alive. Only randomized patients were included in this analysis.

  3. Best Overall Response

    Time frame: Assessed every 8 weeks while on treatment. After the end of treatment, assessed every 3 months for 2 years, then every 6 months for 3 years

    The best overall response is the best response (per RECIST 1.0) recorded from randomization until disease progression/recurrence, taking as reference for progressive disease the smallest measurements recorded since randomization.
