A Phase 1/2 interventional study of Decitabine and Cyclophosphamide Conditioning in Ovarian Cancer and Advanced Malignant Solid Tumor, sponsored by University of Chicago. Not yet recruiting at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-02-20.
Sponsored by University of Chicago · Phase 1/2, Interventional, and Treatment
This phase I/IIA trial studies the side effects and best dose of gene-modified T cells when given with or without decitabine, and to see how well they work in treating patients with malignancies expressing cancer-testis antigens.

Exclusion Criteria:
Known cases of clinically active brain metastases (brain MRI as clinically indicated) because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events. Prior evidence of brain metastasis successfully treated with surgery or radiation therapy will not be exclusion for participation as long as they are deemed under control at the time of study enrollment.
Up to 6 participants will be enrolled to this arm to determine if the study treatment is safe.
Drug: Decitabine · Drug: Cyclophosphamide Conditioning · Biological: NY-ESO-1 TCR/ dnTGFβRII · Drug: Aldesleukin
If the dose tested in Lead in cohort is not found to be safe, the dose of the NY-ESO-1 TCR/ dnTGFβRII cell dose will be lowered and up to 6 participants will be enrolled to this arm.
Drug: Decitabine · Drug: Cyclophosphamide Conditioning · Biological: NY-ESO-1 TCR/ dnTGFβRII · Drug: Aldesleukin
Up to 6 participants with Ovarian Cancer will be enrolled to this arm after the safe dose of NY-ESO-1 TCR/ dnTGFβRII cell is found.
Drug: Decitabine · Drug: Cyclophosphamide Conditioning · Biological: NY-ESO-1 TCR/ dnTGFβRII · Drug: Aldesleukin
Up to 6 participants with other solid tumor cancers will be enrolled to this arm after the safe dose of NY-ESO-1 TCR/ dnTGFβRII cell is found.
Drug: Decitabine · Drug: Cyclophosphamide Conditioning · Biological: NY-ESO-1 TCR/ dnTGFβRII · Drug: Aldesleukin
Decitabine taken by mouth 15 mg/m2/day x 5 days, IV; Days -10 to -6
Cyclophosphamide Conditioning will be 45 mg/kg x 2 days IV; Days -4 \& -3
The dose of NY-ESO-1 TCR/ dnTGFβRII to be tested will vary depending on assigned arm.
Aldesleukin taken by mouth500,000 IU/m2 SC BID; Days +1 to +10
Also known as: (IL-2)
To evaluate autologous in the number of participants with treatment-related adverse events.
To evaluate the safety and tolerability of the autologous NY-ESO-1/ dnTGFβRII engineered T cell therapy in combination with decitabine and low-dose IL2 in patients with advanced malignancies. The irRECIST will be used for tumor response assessment performed at 6 weeks, 3 months, 6 months and 9 months.
Time frame: 2 years
To evaluate modified cells using immune- related Response Evaluation Criteria in Solid Tumors (irRECIST).
To evaluate the persistence of genetically modified cells in the peripheral blood, and at tumor sites (where available). The irRECIST will be used for tumor response assessment performed at 6 weeks, 3 months, 6 months and 9 months.
Time frame: 2 years
Objective response rate (ORR) tumor effect
To examine the effect of the treatment on tumor as measured by objective response rate (ORR) assessed by immune- related Response Evaluation Criteria in Solid Tumors (irRECIST).
Time frame: 6 weeks, 3 months, 6 months and 9 months.
Progression free survival (PFS) tumor effect
To examine the effect of the treatment on tumor as measured by progression free survival (PFS), assessed by immune- related Response Evaluation Criteria in Solid Tumors (irRECIST).
Time frame: From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 9 months.
