Pazopanib Hydrochloride or a Placebo in Treating Patients With Non-Small Cell Lung Cancer Who Have Received First-Line Chemotherapy

• Status: Terminated
• Trial end date: 2015-06-01
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Pazopanib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. It is not yet known whether pazopanib hydrochloride is more effective than a placebo in treating patients with non-small cell lung cancer that has not progressed after first-line chemotherapy.

PURPOSE: This randomized phase II/III trial is studying how well giving pazopanib hydrochloride works and compares it with giving a placebo in treating patients with non-small cell lung cancer who have received first-line chemotherapy.

• Phase: Phase 2/Phase 3
• Accepts Healthy Volunteers?: No

• Lead Sponsor: European Organisation for Research and Treatment of Cancer - EORTC

Criteria

DISEASE CHARACTERISTICS:

• Histologically or cytologically confirmed non-small cell lung cancer (NSCLC) meeting the following criteria:

• Any histology

• Stage IIIB-IV disease

• Newly diagnosed or recurrent disease (after surgery or radical radiotherapy) proven on cytology or histology before induction chemotherapy

• In case of adjuvant chemotherapy after previous surgery, time interval from start of previous treatment to induction chemotherapy for metastatic disease is 12 months

• May or may not have measurable disease as defined by RECIST criteria

• Must not have progressed during the 4 courses of initial chemotherapy

• For patient presenting with measurable disease, there must be documented radiographic evidence of response (complete response, partial response, or stable disease) according to RECIST 1.1 criteria

• For patients without measurable disease, there must be no symptomatic/clinical progression

• EGFR wild-type or unknown (known EGFR mutations are not eligible)

• Brain metastases allowed provided they are controlled and the patient must present with a performance status (PS) of 0-1 after the 4 courses of chemotherapy and at least 1 week off steroids

• No known endobronchial lesions and/or lesions infiltrating major pulmonary vessels that increase the risk of pulmonary hemorrhage, including any of the following:

• Large protruding endobronchial lesions in the main or lobar bronchi

• Endobronchial lesions in the segmented bronchi are allowed

• Lesions extensively infiltrating the main or lobar bronchi

• Minor infiltrations in the wall of the bronchi are allowed

• Lesions infiltrating major pulmonary vessels (contiguous tumor and vessels)

• Tumors touching but not infiltrating (abutting) the vessels are acceptable

PATIENT CHARACTERISTICS:

• WHO performance status (PS) 0-2

• PS 2 capped at 15% of the study population

• Elderly population (i.e., > 70 years old) capped at 15% and must be PS 0-1

• Life expectancy ≥ 12 weeks

• ANC ≥ 1.5 x 10^9/L

• Platelet count ≥ 100 x 10^9/L

• Hemoglobin ≥ 9 g/dL

• PT or INR ≤ 1.2 times upper limit of normal (ULN)

• PTT ≤ 1.2 times ULN

• Bilirubin ≤ 1.5 times ULN

• AST/ALT ≤ 2.5 times ULN

• Serum creatinine ≤ 1.5 mg/dL OR creatinine clearance ≥ 50 mL/min

• Urine protein:creatinine ratio ≤ 1 OR ≤ 1.0 g of protein by 24-hour urine collection

• May only be randomized in this trial once

• Not pregnant or nursing

• Negative pregnancy test

• Fertile patients must use effective contraception 2 weeks prior to, during, and for at least 1 month after completion of study therapy

• Corrected QT interval (QTc) ≤ 480 msec on normal 12-lead ECG

• If QTc interval is > 480 msec, then 2 additional ECGs should be obtained over a brief period of time (e.g., within 15-20 minutes) to confirm the abnormality and the average QTc interval will be determined from the 3 ECG tracings by manual evaluation and will be used to determine if the patient will be excluded from the study

• No history of any of the following cardiovascular conditions within the past 6 months:

• Cardiac angioplasty or stenting myocardial infarction

• Unstable angina

• Coronary artery bypass graft surgery

• Symptomatic peripheral vascular disease

• No NYHA class III-IV congestive heart failure (no class II, III, or IV for elderly patients)

• LVEF normal

• No other malignancy within the past 2 years except for non-small cell lung cancer

• No poorly controlled hypertension, defined as blood pressure (BP) > 140/90 mm Hg

• Initiation or adjustment of antihypertensive medications is permitted prior to study entry provided blood pressure is reassessed on two occasions that are separated by a minimum of 1 hour and the mean systolic BP/diastolic BP values must be ≤ 140/90 mm Hg

• No cerebrovascular accident (at any time in the past), transient ischemic attack, deep venous thrombosis (DVT), or pulmonary embolism within the past 6 months

• Patients with recent DVT who have been treated with therapeutic anticoagulating agents and remained stable for at least 6 weeks are eligible

• No hemoptysis within the past 6 weeks (patients with a history of hemoptysis associated with metastatic disease must undergo a bronchoscopy to rule out endobronchial lesions and patients with an endobronchial lesion will be excluded from the study)

• No history of clinically significant gastrointestinal disorders, including any of the following:

• Malabsorption syndrome

• Major resection of the stomach or small bowel that could affect the absorption of the study drug

• Active peptic ulcer disease

• Known intraluminal metastatic lesions with risk of bleeding

• Inflammatory bowel disease

• Ulcerative colitis

• Other gastrointestinal conditions with increased risk of perforation

• No history of abdominal fistula, gastrointestinal perforation, or intra-abdominal abscess within the past 28 days

• No evidence of active bleeding or bleeding diathesis

• No trauma within the past 28 days

• No nonhealing wound, fracture, or ulcer

• No known immediate or delayed hypersensitivity reaction or idiosyncrasy to drugs chemically related to pazopanib hydrochloride

• No psychological, familial, sociological, or geographical condition potentially hampering compliance with the study protocol and follow-up schedule

PRIOR CONCURRENT THERAPY:

• See Disease Characteristics

• No ongoing toxicity from prior anticancer therapy that is > grade 1 (except alopecia) and/or that is progressing in severity

• At least 6 months since prior amiodarone

• At least 14 days since prior CYP3A4 substrates

• At least 2 weeks since prior palliative radiotherapy

• No major surgery within the past 28 days

• No prior multi-target tyrosine kinase inhibitor (TKI), bevacizumab, or cetuximab (as part of induction therapy)

• Prior radical radiotherapy allowed provided it was at least 12 months from start of induction chemotherapy for metastatic disease

• Concurrent anticoagulant therapy allowed provided the patient's PT, INR, or PTT is stable and within the recommended range for the desired level of anticoagulation
