Brief Summary
This phase II trial studies the effect of belinostat and SGI-110 (guadecitabine) or ASTX727 in treating patients with conventional chondrosarcoma that cannot be removed by surgery (unresectable) and has spread from where it first started (primary site) to other places in the body (metastatic). Belinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as guadecitabine and ASTX727, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving belinostat in combination with guadecitabine or ASTX727 may lower the chance of unresectable and metastatic chondrosarcoma growing or spreading.

Outcome Measures
Primary Outcomes (1)
Objective Response Rate (ORR) in Belinostat, ASTX727
Best Objective Response per RECIST Version 1.1 criteria. CR, complete response defined by the disappearance of all target lesions; PR, partial response defined by at least a 30% decrease in the sum of the diameters of target lesions; SD, stable disease defined by neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease; PD, progressive disease defined by at least a 20% increase in the sum of the diameters of target lesions or the appearance of one or more new lesions.
Within 6 months after initiating study treatment
Secondary Outcomes (5)
Presence of Treatment Related Adverse Events (AEs) in Belinostat, ASTX727
Up to 24 months post treatment
Progression Free Survival (PFS) in Belinostat, ASTX727
Time from first treatment with the study drug to the earliest of either disease progression or death from any cause, assessed up to 24 months.
Presence of Treatment Related Adverse Events (AEs) in Belinostat, SGI-110
Up to 24 months post treatment
Progression Free Survival (PFS) in Belinostat, SGI-110
Time from first treatment with the study drug to the earliest of either disease progression or death from any cause, assessed up to 24 months.
Objective Response Rate (ORR) in Belinostat, SGI-110
Within 6 months after initiating study treatment.
Other Outcomes (4)

Study Arms (1)
Treatment (belinostat, guadecitabine, ASTX727)
EXPERIMENTALPatients receive guadecitabine SC or ASTX727 PO on days 1-5. Patients also receive belinostat IV over 30 minutes on days 1-5. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo collection of blood during screening, tumor biopsy during screening and on study, and MRI or CT throughout the trial.

Eligibility Criteria
You may qualify if:
- Patients must have biopsy-proven conventional chondrosarcoma (CS) which is:
- Either metastatic or locally advanced and unresectable, and
- Measurable at study entry according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 criteria, and
- Amenable to biopsy with imaging guidance at no or acceptable risk to the patient as defined by institutional guidelines for research-related biopsies or the treating investigator's assessment
- In addition, the following criteria must be met:
- Patients must have at least one lesion measurable by RECIST version 1.1 criteria which has not been previously irradiated
- Patients who have histologic evidence of grade 1 chondrosarcoma only must either be symptomatic from their disease in the opinion of the treating investigator or demonstrate radiographic evidence of disease progression in the 3 months prior to initiation of study treatment
- Note: Pathology review and confirmation of diagnosis will occur at the site enrolling the patient on this study
- Patients may have been treated with any number of prior systemic therapies. Because there are no Food and Drug Administration (FDA)-approved treatments for this disease, patients who have received no prior systemic therapy are also eligible. However, disease must be deemed surgically unresectable
- Age \>= 18 years. Chondrosarcoma is rarely encountered in children and adolescents
- Eastern Cooperative Oncology Group (ECOG) performance status =\< 2 (Karnofsky \>= 60%)
- Absolute neutrophil count \>= 1,000/mm\^3
- Hemoglobin 8 g/dL
- Platelet count \>= 75,000/mm\^3
- Total bilirubin =\< 1.5 x institutional upper limit of normal (ULN)
- +11 more criteria
You may not qualify if:
- Patients with dedifferentiated, mesenchymal, or clear cell chondrosarcoma are not eligible
- Patients who have not recovered from adverse events (AEs) (i.e., have residual toxicities \> grade 1) due to prior anti-cancer therapy are not allowed, with the exceptions of alopecia and endocrinopathies from prior immunotherapy-based treatments that are well-controlled with hormone replacement. In addition, the following time periods must elapse between the last dose of prior anti-cancer treatment and initiation of study treatment on this protocol:
- Cytotoxic chemotherapy or biologic, including immunotherapy: 28 days
- Small molecule targeted drug: 21 days or 5 half-lives, whichever is shorter. If 5 half-lives is shorter than 21 days, then 21 days applies.
- Radiation: 28 days, except for palliative radiation, for which 14 days applies
- Patients who are receiving any other investigational agents
- Patients with known history of allergic reactions or sensitivity attributed to compounds of similar chemical or biologic composition to SGI-110 (guadecitabine), its active metabolite decitabine, or ASTX727, or belinostat
- Chronic use of any medications or substances that are strong inhibitors of UGT1A1 is not allowed. Patients must switch to alternative medications 7-14 days before treatment with belinostat. Because the lists of these agents are constantly changing, it is important to regularly consult a frequently-updated medical reference. As part of the enrollment/informed consent procedures, the patient will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the patient is considering a new over-the-counter medicine or herbal product
- Patients with any known UGT1A1 polymorphism, heterozygous or homozygous, associated with reduced function (UGT1A1\*6, UGT1A1\*28, or UGT1A1\*60)
- Patients with uncontrolled intercurrent illness
- Patients with psychiatric illness/social situations that would limit compliance with study requirements
- Pregnant women are excluded from this study because SGI-110 (guadecitabine) is a derivative of decitabine, and ASTX727 contains the agent decitabine, which has the potential for teratogenic or abortifacient effects, and because belinostat may cause teratogenicity and/or embryo-fetal lethality by virtue of targeting actively dividing cells. Because there is an unknown but potential risk for AEs in nursing infants secondary to treatment of the mother with SGI-110 (guadecitabine), ASTX727 and belinostat, breastfeeding should be discontinued
- Prolongation of the heart-rate corrected QT (QTc) interval \>= 450 ms (i.e., grade 1 or higher) on the screening electrocardiogram (ECG) prior to initiation of study treatment. If baseline QTc on screening ECG is \>= 450 ms (i.e., grade 1 or higher):
- Check potassium and magnesium serum levels, and
- Correct any identified hypokalemia and/or hypomagnesemia and repeat ECG to confirm a QTc interval \< 450 ms
