Tivozanib for Recurrent Glioblastoma

Phase 2

Completed

Conditions: Glioblastoma

Interventions: Drug: Tivozanib

Registration Number: NCT01846871

Lead Sponsor: Massachusetts General Hospital

Brief Summary: This research study is a Phase II clinical trial, which tests the safety and effectiveness of an investigational drug to learn whether the drug works in treating a specific cancer. "Investigational" means that the study drug tivozanib is still being studied. It also means that the FDA has not yet approved tivozanib for your type of cancer.

Tivozanib is an anti-angiogenesis medicine that fights different types of cancer by blocking the blood supply to the tumor, so that the tumor does not receive the nutrients it requires to grow.

In this research study, we are looking to see what effects, good and bad, tivozanib will have on you and your disease.

Detailed Description: If you are willing to participate in this study, you will be asked to undergo some screening tests and procedures that confirm you are eligible. Many of these tests and procedures are likely to be part of regular cancer care and may be done even if it turns out taht you do not take part in the research study. If you have had some of these tests or procedures recently, they may or may not have to be repeated. The screening process may include the following: a medical history, mini-mental status exam, physical exam, performance status, electrocardiogram, blood tests, urine test. If these tests show that you are eligible to participate in the research study, you will begin the study treatment. If you do not meet the eligibility criteria, you will not be able to participate in this research study.

If you take part in this research study, you will be given a study drug-dosing calendar for each treatment cycle. Each treatment cycle lasts 28 days (4 weeks) during which time you will be taking the study drug once daily for 3 weeks and then no study drug for the last week of each cycle. The diary will also include special instructions for taking the study drug.

During all cycles you will have a physical exam and you will be asked questions about your general health and specific questions about any problems that you might be having and any medications you may be taking.

Standard contrast-enhanced (CE) MRI scans will be done prior to all odd-numbered study cycles. Vascular MRI scans will be done prior to start of treatment, Day 1 of treatment and prior to all even-numbered cycles. These studies will be done in the Charlestown Navy Yard.

We would like to keep track of your medical condition for up to 24 months after your last dose of study treatment. We would like to do this by calling you on the telephone once a year to see how you are doing. Keeping in touch with you and checking your condition every year helps us look at the long-term effects of the research study.

Arm && Interventions

Group	Intervention	Description
Tivozanib	Tivozanib	1.5 mg daily for 3 weeks, with 1 week off.

Primary Outcome Measures

Name	Time	Method
Number of Patients Alive and Progression Free After 6 Months	6 months	To determine the number of patients with recurrent glioblastoma (GBM) alive and progression free 6 months (PFR6) after start of tivozanib therapy

Secondary Outcome Measures

Name	Time	Method
Best RANO Criteria Response	2 years	Best response as assessed by Response Assessment in Neuro-Oncology (RANO) criteria. Complete response * disappearance of all enhancing disease * sustained for at least 4 weeks * stable/improved non-enhancing FLAIR/T2W lesions * no new lesions * no corticosteroids * clinically stable/improved Partial response \>50% or more decrease of all measurable enhancing lesions * sustained for at least 4 weeks * no progression of non-measurable disease * stable/improved non-enhancing FLAIR/T2W lesions * no new lesions * stable/reduced corticosteroids * clinically stable/improved Stable disease * does not qualify for complete response, partial response or progression * stable non-enhancing FLAIR/T2W lesions * stable or reduced corticosteroids * clinically stable Progression \>25% or more increase in enhancing lesions despite stable/increasing steroid dose * increase in non-enhancing FLAIR/T2W lesions, not attributable to other non-tumor causes * any new lesion * Clinical deterioration
Median Progression-Free Survival	From the start of treatment until death or progression, median duration of approximately 2 months	Progression free survival is measured as the amount of time from the start of treatment until the time of death or disease progression. Progressive disease was assessed using MacDonald Criteria Progressive disease: Progressive neurologic abnormalities not explained by causes unrelated to tumor 40 progression (example: anti-epileptic drug or corticosteroid toxicity, electrolyte abnormalities, hyperglycemia, etc.) or a greater than 25% increase in the volume of the tumor by MRI scan. If neurologic status deteriorates on a stable or increasing dose of corticosteroids, or if new lesions appear on serial MRI scans, this will also be considered PD.
Number of Participants With Treatment Related Serious Adverse Events	From the start of treatment until disease progression, unacceptable toxicity, or death; median duration of approximately 2 months	The number of participants with serious adverse events deemed possibly, probably, or definitely related to treatment. Adverse events were assessed using Common Terminology Criteria for Adverse Events (CTCAE 4).
Median Overall Survival	From the start of treatment until the time of death, median duration of approximately 8 months	Overall survival is measured from the start of treatment until the time of death.
Steroid Dosage	2 years	The number of participants on steroids at baseline and the number of participants that increased or decreased their use of steroids during the course of treatment. Participants that required an increase and decrease in steroid use over the course of treatment were counted in both categories.
Change in Tumor Volume	Baseline, Cycle 1 day 2, pre-cycle 2, pre-cycle 3 (1 cycle= 4 weeks)	Change in volume of the tumor in cubic centimeters at the given time points as compared to baseline
Median Apparent Diffusion Coefficient (ADC)	Baseline, Cycle 1 day 2, pre-cycle 2, pre-cycle 3 (1 cycle= 4 weeks)	Change in the the median ADC value from baseline at the given timepoints. Apparent diffusion coefficient (ADC) is a measure of the magnitude of diffusion (of water molecules) within tissue.
Median Ktrans	Baseline, Cycle 1 day 2, pre-cycle 2, pre-cycle 3 (1 cycle= 4 weeks)	Change in the the median Ktrans value from baseline at the given time points. The volume transfer constant (Ktrans) reflects the efflux rate of gadolinium contrast from blood plasma into the tissue extravascular extracellular space (EES)
Relative Oxygen Saturation	Baseline, Cycle 1 day 2, pre-cycle 2, pre-cycle 3 (1 cycle= 4 weeks)	The change in relative O2 saturation from baseline to the given time points. Oxygen saturation is a relative measure of the concentration of oxygen that is dissolved or carried in a given medium as a proportion of the maximal concentration that can be dissolved in that medium.
