Docetaxel With or Without FGFR Inhibitor AZD4547 in Treating Patients With Recurrent Non-Small Cell Lung Cancer

Phase 1

Completed

• Conditions: Squamous Cell Lung Cancer; Recurrent Non-small Cell Lung Cancer
• Interventions: Drug: docetaxel; Drug: AZD4547

• Registration Number: NCT01824901
• Lead Sponsor: ECOG-ACRIN Cancer Research Group

Brief Summary

This randomized phase I/II trial studies the side effects and best dose of fibroblast growth factor receptor (FGFR) inhibitor AZD4547 when given with docetaxel and to see how well it works in treating patients with recurrent non-small cell lung cancer. Drugs used in chemotherapy, such as docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. FGFR inhibitor AZD4547 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether docetaxel and FGFR inhibitor AZD4547 are more effective when given together or separately.

Detailed Description

PRIMARY OBJECTIVES:

I. Determination of a recommended phase II dose for the combination of docetaxel and AZD4547 (FGFR inhibitor AZD4547). (Phase I) II. Estimation and comparison of progression-free survival (PFS) of each treatment arm. (Phase II)

SECONDARY OBJECTIVES:

I. Pharmacokinetic evaluation of docetaxel with or without concomitant AZD4547. Pharmacokinetic evaluation of AZD4547 with concomitant docetaxel. (Phase I) II. Safety assessment and toxicity characterization of the combination. (Phase I) III. Initial assessment of clinical activity of the combination. (Phase I) IV. Response rate. (Phase II) V. Overall survival. (Phase II) VI. Estimation of response to single agent AZD4547 among patients who crossover from single agent docetaxel. (Phase II) VII. Further safety assessment and toxicity characterization of AZD4547 alone and in combination with docetaxel. (Phase II)

OUTLINE: This is a phase I, dose-escalation study of FGFR inhibitor AZD4547 followed by a randomized phase II study.

PHASE I:

Patients receive docetaxel intravenously (IV) over 60 minutes on day 1 and FGFR inhibitor AZD4547 orally (PO) twice daily (BID) on days 2-15 of course 1 and days 1-14 of all subsequent courses. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

PHASE II, STEP I: Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive docetaxel IV over 60 minutes on day 1. Treatment repeats every 21 days for up to 6 courses in the absence of disease progression or unacceptable toxicity. Patients who experience progressive disease may then receive FGFR inhibitor AZD4547 PO BID on days 1-14.

ARM II: Patients receive docetaxel IV as in Arm I and FGFR inhibitor AZD4547 PO BID on days 1-14.

In both arms, courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

PHASE II, STEP II:

Patients receive FGFR inhibitor AZD4547 PO BID on days 1-14. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 3 years.

This study opened to accrual on September 19, 2013 and was suspended to accrual on January 29, 2014 after each of the first two patients had been registered to the first dose level of the phase I and experienced dose limiting toxicities (DLTs) during week 1 of cycle 1. The study was subsequently terminated on April 17, 2014 after having met the predefined criteria for closure per the phase I study design.

Primary Outcome Measures

Name	Time	Method
Maximum Tolerated Dose (MTD) of FGFR Inhibitor AZD4547	Assessed during cycle 1 (21 days)	A total of 3 dose levels of AZD4547 were planned: 40mg (level 1), 60mg (level 2), and 80mg (level 3) in combination with a standard dose of docetaxel (75mg/m\^2). The starting dose level of AZD4547 was 40 mg. This portion of the study used a standard 3+3 design with patients enrolled in cohorts of 3. The plan was to recommend the maximum tolerated dose (MTD) as the dose level to be used in the phase II portion of the study. MTD is defined as the highest dose level at which less than or equal to 1 of 6 subjects experience dose limiting toxicity (DLT).
