Further study details as provided by GlaxoSmithKline:

Primary Outcome Measures:
  • First course tolerability with rising dose of topotecan to determine the maximum tolerated dose of topotecan when given with pazopanib daily. [ Time Frame: 5 weeks ]

Secondary Outcome Measures:
  • Indications of efficacy through tumour shrinkage. Specific biomarker analysis. [ Time Frame: 12 weeks ]

Enrollment: 50
Study Start Date: September 2008
Study Completion Date: June 2013
Primary Completion Date: June 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Treatment Arm A
Daily oral pazopanib in combination with weekly oral topotecan. Initially rising dose to determine the maximum tolerated dose: finally an expanded cohort treated at the maximum tolerated dose.
Drug: topotecan
Topoisomerase I inhibition.
Drug: pazopanib
Tyrosine kinase inhibitor
Experimental: Treatment Arm B
Daily oral pazopanib in combination with oral topotecan given for 5 consecutive days every 21 days. Initially rising dose to determine the maximum tolerated dose; finally an additional cohort of patients treated at the maximum tolerated dose.
Drug: topotecan
Topoisomerase I inhibition.
Drug: pazopanib
Tyrosine kinase inhibitor

Detailed Description:
A Phase I Open-label Study of the Safety, Tolerability, and Pharmacokinetics of Two Schedules of Oral Topotecan in combination with Pazopanib in Subjects with Advanced Solid Tumors

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria -

  • signed, written informed consent.
  • at least 18 years of age.
  • ECOG performance status 0 or 1.
  • Subjects must have histologically or cytologically confirmed diagnosis of advanced cancer and a solid tumor malignancy that has relapsed or is refractory to standard therapy or for which there is no established therapy.
  • able to swallow and retain oral medications.
  • females are eligible to enter and participate in this study providing adequate established contraception is being practiced.

Exclusion Criteria

  • had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C)
  • received an investigational drug within 30 days or 5 half-lives (whichever is longer).
  • received prior treatment with pazopanib/investigational anti-angiogenic compounds.
  • presence of uncontrolled infection.
  • pregnant or lactating.
  • poorly controlled hypertension (SBP of ? 140 mmHg, or DBP of ? 90 mmHg.
  • Class III or IV heart failure as defined by the New York Heart Association (NYHA) functional classification system.-
  • arterial thrombi, myocardial infarction, admission for unstable angina, uncontrolled or symptomatic arrhythmia, cardiac angioplasty, or stenting within the last 6 months.
  • any unresolved bowel obstruction or diarrhea ? Grade 1.
  • received an allogeneic bone marrow transplant.
  • known immediate or delayed hypersensitivity reaction or idiosyncrasy to drugs chemically related to pazopanib or topotecan.
  • any serious and/or unstable pre-existing medical, psychiatric, or other conditions that could interfere with subject's safety, obtaining informed consent or compliance with the study.
  • psychological, familial, sociological, or geographical conditions that do not permit compliance with the protocol.
  • clinical history, current alcohol or illicit drug use which, in the judgment of the investigator, would interfere with the subject's ability to comply with the dosing schedule and protocol-specified evaluations.
