Conditions
Brief summary
This phase II/III trial studies how well FGFR inhibitor AZD4547 (AZD4547) works in treating patients with stage IV squamous cell lung cancer that has come back after previous treatment. This is a sub-study that includes all screened patients positive for the fibroblast growth factor receptor (FGFR) biomarker. FGFR can cause tumor cells to grow more quickly. AZD4547 may decrease the activity of FGFR and may be able to shrink tumors.
Detailed description
PRIMARY OBJECTIVES: I. To evaluate if there is sufficient evidence to continue to the Phase III component by evaluating the objective response rate (ORR) with AZD4547 in FGFR-positive patients. (Phase II) II. If the study meets the criteria specified in S1400, the study will be amended to include a follow-on randomized Phase III trial. (Phase III) SECONDARY OBJECTIVES: I. To evaluate investigator-assessed progression free survival (IA-PFS) and overall survival (OS) in FGFR-positive patients treated with AZD4547. (Phase II) II. To evaluate the duration of response (DoR) among FGFR positive patients treated with AZD4547 who achieve a complete response (CR) or partial response (PR) (confirmed and unconfirmed) by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1. (Phase II) III. To evaluate the frequency and severity of toxicities associated with AZD4547 in FGFR positive patients. (Phase II) TRANSLATIONAL MEDICINE OBJECTIVES: I. To identify additional predictive tumor/blood biomarkers that may modify response or define resistance to the AZD4547 beyond the chosen biomarker for biomarker-driven sub-studies. II. To identify potential resistance biomarkers at disease progression. III. To establish a tissue/ blood repository from patients with refractory squamous cell carcinoma (SCCA) of the lung. OUTLINE: As of 12/18/2015, patients are assigned to Arm I. ARM I: Patients receive FGFR inhibitor AZD4547 orally (PO) twice daily (BID) on days 1-21. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity. ARM II (CLOSED TO ACCRUAL 12/18/2015): Patients receive docetaxel intravenously (IV) on day 1. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity. Upon progression, patients may be eligible to re-register to Arm III. ARM III: Patients in Arm II eligible for re-registration receive FGFR inhibitor AZD4547 PO BID on days 1-21. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, all patients are followed up every 6 months for the first 2 years and then at the end of the year 3 from date of sub-study/re-registration.

Pre-assignment details
33 participants were enrolled to AZD4547 arm and 10 to Docetaxel. 8 participants on AZD4547 and 1 participant on docetaxel were ineligible. 2 participants on Docetaxel were re-registered to AZD4547 after progression on Docetaxel, and for analysis, were combined with participants on arm 1 (AZD4547). Thus 27 participants were analyzed for AZD4547.
