Monotherapy Pazopanib in Subjects With Advanced Non-Small Cell Lung Cancer

Phase 2

Terminated

Conditions: Lung Cancer, Non-Small Cell

Interventions: Drug: Pazopanib (GW786034)

Registration Number: NCT00549328

Lead Sponsor: GlaxoSmithKline

Brief Summary: This study is designed to evaluate the efficacy and safety of monotherapy pazopanib (a small molecule tyrosine kinase inhibitor of VEGFR-1, VEGFR-2, VEGFR-3, PDGF, and c-kit) in subjects with advanced (Stage IIIB or IV) non-small cell lung cancer.

Detailed Description: Study 109609 is a single-arm, non-randomized, single-stage Phase II study of pazopanib in subjects with Stage IIIB or IV non-small cell lung cancer who have progressed after one or two prior regimens of systemic therapy. The study will be conducted at a limited number of institutions in the US. A total of 40 evaluable subjects will be enrolled and treated. Pazopanib will be given at a dose of 800mg (as determined by previous Phase I studies) orally once per day. Subjects may continue to receive study drug for up to two years unless they experience disease progression or withdraw from treatment for other reasons, or unless the Sponsor terminates the study. A rollover study may be available to those subjects who are exhibiting clinical benefit (stable disease or better). Evaluable subjects will be assessed for response as the primary endpoint.

Use of prohibited medications as defined in protocol.
Use of an investigational agent, including an investigational anti-cancer agent within 28 days, or 5 half-lives, whichever is longer, prior to first dose of study drug.

Arm && Interventions

Group	Intervention	Description
Pazopanib Open-label	Pazopanib (GW786034)	Single-arm, non-randomised, single-stage pazopanib monotherapy.

Primary Outcome Measures

Name	Time	Method
Percentage of Participants Who Achieved Either a Confirmed Complete Response or Partial Response Per RECIST Criteria	Baseline through End of Study (up to 2 years)	The best overall response using Response Evaluation Criteria In Solid Tumors (RESIST) was measured. Complete response is defined as the disappearance of all known lesion(s), confirmed at 4 weeks, and partial response is defined as at least a 30% decrease in the sum of the longest diameters of target lesions taken as a reference to baseline sum of the longest diameters, confirmed at 4 weeks. No formal efficacy analyses were performed due to early termination of the study.

Secondary Outcome Measures

Name	Time	Method
Number of Participants Who Had a Complete or Partial Response, or Stable Disease	Baseline through End of Study (up to 2 years)	Disease control was measured. Stable disease (SD) is defined as neither partial response (at least a 30% decrease in the sum of the longest diameters of target lesions taken as a reference to baseline sum of the longest diameters, confirmed at 4 weeks) nor progressive disease (PD; a 20% increase in the sum of the longest diameters of target lesions, taken as a reference the smallest sum of the longest diameter recorded since the treatment started or the appearance of one or more new lesions. No formal efficacy analyses were performed due to early termination of the study.
Progression-Free Survival	Baseline through End of Study (up to 2 years)	Progression-free survival is defined as the interval between the start of treatment and the earliest date of disease progression or death due to any cause, whichever occurs first. No formal efficacy analyses were performed due to early termination of the study.
Overall Survival	Baseline through End of Study (up to 2 years)	Overall survival is defined as the time from the start of treatment until death due to any cause. No formal efficacy analyses were performed due to early termination of the study.
Levels of Circulating Biomarkers in Plasma	Baseline through End of Study (up to 2 years)	Biomarkers are proteins that respond in a unique way to treatment with the study drug; however, levels of proteins were not collected for this measurement. No formal efficacy analyses were performed due to early termination of the study.
Characterization of Participant Populations by Identification of Intra-tumoral Biomarkers	Baseline through End of Study (up to 2 years)	Biomarkers are proteins that respond in a unique way to treatment with the study drug; however, levels of proteins were not collected for this measurement. No formal efficacy analyses were performed due to early termination of the study.
