AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults with advanced solid tumors that carry an ARID1A gene change. Everyone takes the drug TR115 by mouth.
- Age
- 18 to 70 years
- Sex
- All sexes can join.
- Disease stage
- Advanced solid tumor with an ARID1A mutation and at least one measurable lesion. Cohort 1: platinum-resistant clear cell carcinoma of the ovary, fallopian tube or peritoneum. Cohort 2: endometrial cancer. Cohort 3: other advanced solid tumors, including gastric cancer and urothelial carcinoma.
- Earlier treatment
- Cohort 1: the disease got worse after at least 1 platinum-based treatment. Cohort 2: the disease got worse after at least 1 platinum-based treatment, and earlier immunotherapy failed or was not tolerated. Cohort 3: the disease got worse after at least 1 standard systemic therapy. Earlier treatment with EZH2 or EZH1/2 inhibitors that stopped working cannot have happened.
- Biomarker or test result
- ARID1A gene mutation. People must also be willing to give archival or fresh tumor tissue for marker tests.
Main reasons for not taking part
- Known cancer spread to the central nervous system
- Active hepatitis B or C needing treatment, or HIV infection
- Active infection needing systemic therapy
- Pregnancy or breastfeeding
- Significant heart disease, such as a heart attack within 6 months

- Original description
This is an open-label, multicenter, exploratory Phase II study to evaluate the efficacy and safety of TR115, an EZH2 inhibitor, in patients with advanced solid tumors carrying ARID1A gene mutations. Approximately 50 participants will be enrolled into three cohorts: platinum-resistant ovarian clear cell carcinoma, endometrial cancer with prior immunotherapy failure, and other solid tumors including gastric and urothelial cancers. All participants will receive TR115 at 1200 mg orally twice daily in continuous 28-day cycles until disease progression or unacceptable toxicity. The primary endpoint is objective response rate (ORR). Secondary endpoints include duration of response, progression-free survival, overall survival, disease control rate, and safety. Exploratory biomarker analyses will also be conducted.Read full original descriptionShow less
An Open-Label, Multicenter, Phase II Exploratory Study to Evaluate the Efficacy and Safety of TR115 in Patients With ARID1A-Mutated Advanced Solid Tumors
This is an open-label, multicenter, exploratory Phase II study to evaluate the efficacy and safety of TR115, an EZH2 inhibitor, in patients with advanced solid tumors carrying ARID1A gene mutations. Approximately 50 participants will be enrolled into three cohorts: platinum-resistant ovarian clear cell carcinoma, endometrial cancer with prior immunotherapy failure, and other solid tumors including gastric and urothelial cancers.

Inclusion: Able to understand and provide written informed consent; Age 18 to 70 years, inclusive; Histologically or cytologically confirmed advanced solid tumor with ARID1A mutation; Cohort 1: Platinum-resistant ovarian/fallopian tube/peritoneal clear cell carcinoma with disease progression after ≥1 prior platinum-based regimen. Cohort 2: Endometrial cancer with disease progression after ≥1 prior platinum-based regimen and prior immunotherapy failure or intolerance. Cohort 3: Other advanced solid tumors (including gastric cancer, urothelial carcinoma) with disease progression after ≥1 prior standard systemic therapy; ECOG performance status 0-1; Life expectancy ≥3 months; At least one measurable lesion per RECIST v1.1; Adequate organ function: ANC ≥1.5×10⁹/L, PLT ≥100×10⁹/L, Hb ≥100 g/L (no growth factor or transfusion support within 14 days prior to first dose), TBIL ≤1.5×ULN, ALT/AST ≤2.5×ULN (≤5×ULN if liver metastasis), CrCl ≥50 mL/min, LVEF ≥50%, QTcF <450 ms (male) or <470 ms (female); Willing to provide archival or fresh tumor tissue for biomarker analysis; Male and female participants of childbearing potential must agree to use medically approved contraception during the study and for 6 months after the last dose.
Exclusion: Prior treatment with EZH2 or EZH1/2 inhibitors resulting in disease progression (intolerance permitted); Systemic corticosteroid therapy (>10 mg/day prednisone or equivalent) within 14 days prior to first dose, except for inhaled or topical use; Prior anti-tumor therapy-related adverse events not recovered to ≤Grade 1 (CTCAE v6.0), except alopecia or peripheral neuropathy Grade ≤2; Use of strong or moderate CYP3A4 inhibitors/inducers within 14 days prior to first dose; Inability to swallow oral medication or conditions significantly affecting drug absorption; Active infection requiring systemic therapy; Active hepatitis B or C requiring treatment, or HIV infection; Active autoimmune disease requiring systemic immunosuppressive therapy; Significant cardiovascular disease (e.g., myocardial infarction within 6 months, NYHA Class III/IV heart failure, uncontrolled arrhythmia); Other primary malignancy within 5 years, except cured non-melanoma skin cancer, carcinoma in situ, or thyroid carcinoma; Any other condition that in the investigator's opinion makes the participant unsuitable for the study; Third-space fluid accumulation not controllable by drainage or other means; Known central nervous system (CNS) involvement; Tumor invasion or encasement of major vessels; Pregnancy, lactation, or positive pregnancy test.
