Sunitinib in Sarcomas of the Central Nervous System

Phase 2

Terminated

Conditions: Central Nervous System Sarcoma
Gliosarcoma

Interventions: Drug: Sunitinib
Device: wGT3x-BT

Registration Number: NCT03641326

Lead Sponsor: National Cancer Institute (NCI)

Brief Summary: Background:

A sarcoma is a rare cancer. It grows in the body's connective tissue. Sarcomas in the brain and central nervous system are especially rare. The drug Sunitinib has been approved in many countries for treating other types of rare or advanced cancers. These include kidney, pancreas, and bowel cancer. Researchers want to see if it can help people with sarcomas of the central nervous system.

Objective:

To study the effects of Sunitinib on gliosarcomas or sarcomas of the central nervous system.

Eligibility:

Adults ages 18 and older with a gliosarcoma or sarcoma of the central nervous system

Design:

Participants will be screened with the following tests. Some may be done as part of their regular cancer care:

Medical history

Medication review

Physical exam

Blood, heart, and pregnancy tests

Cranial scans to locate and measure their tumor

Participants will take Sunitinib by mouth every day for 2 weeks and then take none of the drug for 1 week. These 3 weeks equal 1 cycle.

Participants will have 2 study visits in cycle 1. They will have 1 visit in all other cycles. They will answer questions about quality of life and repeat some screening tests.

Participants will take their blood pressure at home weekly. They keep a diary of each dose of Sunitinib and blood pressure reading.

Participants can choose to share data about their physical activity levels and quality of sleep. These participants will wear a small, portable watch-sized accelerometer device on the wrist for 6 cycles.

About 1 month after their last study drug dose, participants will have a final study visit. They will have a physical exam, blood tests, and scans.

Detailed Description: Background:

* Gliosarcoma and primary central nervous system (CNS) sarcomas are malignant brain tumors uniformly associated with poor outcome.

* There are no known effective medical therapies for these cancers.

* Sunitinib is an orally administered small molecule that inhibits signaling of multiple receptor tyrosine kinases including those known to be activated in CNS sarcomas.

Objectives:

To determine the anti-tumor effect of sunitinib in recurrent gliosarcomas and primary CNS sarcomas as assessed by objective response rate (ORR).

Eligibility:

* Patients with histologically proven gliosarcoma and primary CNS sarcoma at disease relapse after failing standard therapy (surgery and irradiation).

* Tumor tissue blocks or 15 unstained slides should be available

* Subjects must be greater than or equal to 18 years old.

* Karnofsky performance status of greater than or equal to 60

* Patients must have adequate organ function.

* Patients must not have received tyrosine kinase inhibitor(s) in the past.

Design:

* This is a prospective, single institution, single arm, multi-cohort phase II study of sunitinib in subjects with recurrent gliosarcoma and primary CNS sarcoma that have failed prior surgery and irradiation (unless radiation therapy was contraindicated).

* Subjects will be classified into three cohorts: 1) Primary gliosarcoma; 2) Secondary gliosarcoma; 3) Primary CNS sarcoma. Cohort expansion will be carried out at indication of promising response.

* Sunitinib will be administered orally using a continuous schedule at 50 mg per day (with dose adjustments allowed for toxicity) for 2 weeks with 1 week off to constitute a 3-week cycle until disease progression or development of intolerable side-effects.

* Toxicity will be assessed every cycle by Common Terminology Criteria in Solid Tumors (CTCAE) version 5.0.

Primary Outcome Measures

Name	Time	Method
Number of Participants With Greater Than 50% Reduction in Objective Response	From enrollment to off study, approximately 3 Months, 1 Week, 4 Days	Objective Response is defined as all participants who had greater than 50% reduction in Complete Response and Partial Response assessed by the Assessment in Neuro-oncology Criteria (RANO criteria). Complete Response is no T1 gadolinium enhancing disease, no new lesions, or corticosteroids, and stable or decreasing T2-weighted-Fluid-Attenuated Inversion Recovery (T2/FLAIR) or clinical status. Partial Response is ≥50% decrease in T1 gadolinium enhancing disease, no new lesions, stable or decreasing T2/FLAIR or corticosteroids, and stable or increasing clinical status.

Secondary Outcome Measures

Name	Time	Method
Evaluation of Tumor Tissue for Biomarkers	end of study, approximately 25 months and 12 days.	To evaluate archival tumor tissue for activation of signaling pathways targeted by sunitinib to establish potential biomarkers of response.
Number of Participants With 6-month Progression Free Survival (PFS)	6 months	Progression is defined as the duration of time from start of treatment to time of progression or death, whichever comes first. PFS was assessed by the Response Assessment in Neuro-oncology Criteria (RANO criteria). Progression is ≥25% increase in T1 gadolinium enhancing disease, increase in T2-weighted-Fluid-Attenuated Inversion Recovery (T2/FLAIR), presence of new lesions, and decrease in clinical status.
Number of Responders and Non-responders With Tumor Markers of Activation	From baseline to end of treatment, approximately 25 months and 12 days.	Molecular profiling of archival tumor tissues was used to identify tumor markers of activation of response to sunitinib in responders and non-responders. A responder is a participant with a Complete Response (CR) or Partial Response (PR), and a non-responder is a participant with Stable Disease (SD) or Progressive Disease (PD) assessed by the Response Assessment in Neuro-oncology Criteria (RANO criteria). CR is no T1 gadolinium enhancing disease, no new lesions, or corticosteroids, and stable or decreasing T2-weighted-Fluid-Attenuated Inversion Recovery (T2/FLAIR). PR is ≥50% decrease in T1 gadolinium enhancing disease, no new lesions, stable or decreasing T2/FLAIR or corticosteroids, and stable or increasing clinical status.

Before (baseline) and during treatment with Sunitinib every 6 weeks, up to approximately 25 months and 12 days.	Dynamic contrast enhanced magnetic resonance imaging (MRI) was performed before and during treatment with sunitinib in responders and non-responders. A responder is a participant with a Complete Response (CR) or Partial Response (PR), and a non-responder is a participant with Stable Disease (SD) or Progressive Disease (PD) assessed by the Response Assessment in Neuro-oncology Criteria (RANO criteria). CR is no T1 gadolinium enhancing disease, no new lesions, or corticosteroids, and stable or decreasing T2-weighted-Fluid-Attenuated Inversion Recovery (T2/FLAIR). PR is ≥50% decrease in T1 gadolinium enhancing disease, no new lesions, stable or decreasing T2/FLAIR or corticosteroids, and stable or increasing clinical status. SD is \<50% decrease in T1 gadolinium enhancing disease but \< 25% increase, no new lesions, stable or decreasing T2/FLAIR or corticosteroids, and stable or increase in clinical status. PD is ≥25% increase in T1 gadolinium enhancing disease.
Mean Symptom Severity and Interference From Baseline Using the MD Anderson Symptom Inventory-Brain Tumor Module (MDASI-BT)	Baseline and off treatment, approximately 25 months and 12 days	Participants reported outcome measures using a self-reported symptom severity and interference with daily activities using the MDASI-BT. The MDASI-BT consists of symptoms rated on an 11-point scale (0 to 10) to indicate the presence and severity of the symptom, with 0 being "not present" and 10 being "as bad as you can imagine." Each symptom is rated at its worst in the last 24 hours. All patients with at least one valid questionnaire will be included in the analyses. This outcome measure was predicated on change. Differences of at least 2 points will be classified as the minimum clinically meaningful change in the symptom severity and symptom interference measures.
