Background:

Clear cell sarcoma (CCS) is a rare, aggressive tumor. Chondrosarcoma (CS) is one of the most common malignant bone tumors in adults. People with these types of advanced cancers usually don t have effective treatment options. Researchers want to see if a drug can help.

Objective:

To test the good and bad effects of atezolizumab and to see if it causes cancer to shrink by at least one-quarter compared to its present size.

Eligibility:

People age 2 and older with advanced CCS or CS that is not curable by surgery and for which there is no standard treatment.

Design:

Participants will be screened with a medical history and physical exam. They will have an assessment of how they are doing with their daily living activities. They will have heart tests. They will give blood samples. They will have imaging scans to measure their tumor. This may include computed tomography scans or other imaging tests such as ultrasound, magnetic resonance imaging, or positron emission tomography.

Screening tests will be repeated during the study.

Participants will get atezolizumab through a vein in the arm once every 3 weeks (21 days). They will be monitored for side effects. They will take the study drug until their tumor grows or they have serious side effects.

Adult participants will have tumor biopsies.

Participants blood and tumor samples will be used for protein and gene testing.

After they stop taking the study drug, participants will be followed for 30 days from their last treatment date or until a new treatment is started. They will have a telephone call from the Study Team.

Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately.

-Ability to understand and the willingness to sign a written informed consent document or a parent/guardian able to do the same.

EXCLUSION CRITERIA:

-Any prior therapy must have been completed greater than or equal to 4 weeks or, if known, greater than or equal to 5 half-lives of the prior agent (whichever is shorter) prior to enrollment on protocol (minimum of 1 week between prior therapy and study enrollment), and the participant must have recovered to eligibility levels from prior toxicity. Patients should be at least 6 weeks out from nitrosoureas and mitomycin C. Prior definitive radiation should have been completed greater than or equal to 4 weeks or palliative radiation should have been completed greater than or equal to 2 weeks prior to study enrollment and all associated toxicities resolved to eligibility levels (patients on study may be eligible for palliative radiotherapy to non-targeted lesions after 2 cycles of therapy at the PI s discretion). Patients who have had prior monoclonal antibody therapy must have completed that therapy greater than or equal to 6 weeks (or 3 half-lives of the antibody, whichever is shorter) prior to enrollment on protocol (minimum of 1 week between prior therapy and study enrollment). A patient who has received a cumulative dose of >350 mg/m^2 enrolled if their ejection fraction measured by an echocardiogram is within normal institutional limits.

-Prior treatment with anti-PD-1, or anti-PD-L1 therapeutic antibody or pathway-targeting agents.

--Patients who have received prior treatment with anti-CTLA-4 may be enrolled, provided the following requirements are met:

-Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.

-Pregnant women are excluded from this study because atezolizumab is an investigational agent with the unknown potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with atezolizumab, breastfeeding should be discontinued if the mother is treated with atezolizumab.
