CPI-0209 in Combination with Carboplatin for the Treatment of Patients with Platinum Sensitive Recurrent Ovarian, Fallopian Tube or Primary Peritoneal Cancer
This phase I trial tests the safety, side effects, and best dose of CPI-0209 in combination with carboplatin in treating patients with ovarian, fallopian tube or primary peritoneal cancer that has responded to previous treatment with a platinum-based drug (platinum-sensitive) and has come back after a period of improvement (recurrent). CPI-0209, a small molecule drug, acts by blocking the activity of two forms of a protein called enhancer of zeste homolog (EZH) methyltransferase, EZH2 and EZH1, and may prevent tumor cells from growing. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of tumor cells. CPI-0209 in combination with carboplatin may be safe, tolerable and/or effective in treating patients with platinum sensitive recurrent ovarian, fallopian tube or primary peritoneal cancer.
Inclusion Criteria
- Women ≥ 18 years old with platinum-sensitive recurrent ovarian, fallopian or primary peritoneal cancer (defined as recurrent disease > 6 months after completing last platinum- based chemotherapy) that are eligible to receive platinum-based chemotherapy)

- Must have had at least 1 prior line of platinum-based therapy, prior bevacizumab or poly (ADP-ribose) polymerase inhibitor (PARPi) use are allowed. Women with germline BRCA mutations should be considered for PARPi maintenance as standard of care treatment prior to consideration of clinical trial enrollment

- Serum creatinine ≤ 1.5mg/dL or 24-hour clearance ≥ 50mL/min
- Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) < 2.5 x upper limit of normal (ULN) (or < 5 x ULN if liver metastasis are present)
- Total bilirubin ≤ ULN or total bilirubin ≤ 3.0 x ULN or direct bilirubin ≤ 1.5 x ULN in patients with well-documented Gilbert's syndrome
- Hemoglobin ≥ 9 gm/dl

- Able to provide informed consent and comply with all study protocol
- Treated central nervous system (CNS) metastasis allowed if treatment is completed ≥ 8 weeks prior to enrollment. Patients must be asymptomatic off systemic corticosteroids for at least 4 weeks after completion of radiation therapy. CNS disease must be stable or regressed on repeat imaging performed at least 4 weeks after completion of therapy
- Women of child-bearing potential (those who have had a menstrual cycle within the last year and have not had a tubal ligation or surgical removal of both ovaries and/or hysterectomy) and their partners must agree to abstain from vaginal intercourse or use and continue highly effective methods of contraception for at least 183 days after discontinuation of study treatment. * Total abstinence when this is in line with the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception * Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy), total hysterectomy, or tubal ligation at least six weeks before taking study treatment. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow-up hormone level assessment. * Male sterilization (at least 6 months prior to screening). The vasectomized male partner should be the sole partner for that patient * Use of oral, injected or implanted hormonal methods of contraception or placement of an intrauterine device (IUD) or intrauterine system (IUS), or other forms of hormonal contraception that have comparable efficacy (failure rate < 1%), for example hormone vaginal ring or transdermal hormone contraception * In case of use of oral contraception, women should have been stable on the same pill for a minimum of 3 months before taking study treatment * Note: Oral contraceptives are allowed but should be used in conjunction with a barrier method of contraception due to unknown effect of drug-drug interaction. Women are considered post-menopausal and not of childbearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks ago. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow-up hormone level assessment is she considered not of childbearing potential
Exclusion Criteria
- Borderline or low malignant potential histology
- Platinum-resistant disease (as defined as progressive disease [PD] within 6 months of completion of chemotherapy with a platinum agent)
- Known hypersensitivity to any of the excipients of CPI-0209
- Gastrointestinal (GI) dysfunction or disease that may significantly alter the absorption of the study drugs
- Concurrent malignancy or malignancy within 3 years prior to starting study drug with the exception of adequately treated basal or squamous cell carcinoma, non-melanomatous skin cancer or curatively resected cervical cancer or per physician discretion that the previous cancer was adequately treated with curative intent and unlikely to recur (the study principal investigator [PI] must concur with this determination)
- History of HIV infection
- Has an active infection requiring systemic treatment
- Patient has any other concurrent severe and/or uncontrolled medical condition that would, in the investigator’s judgment, cause unacceptable safety risks and contraindicate patient’s participation in the clinical study or compromise compliance with the protocol (e.g. chronic pancreatitis, chronic active hepatitis, active untreated or uncontrolled fungal, bacterial or viral infections, significant cardiac/pulmonary disease etc.)
- Patient is currently receiving warfarin or other coumadin-derived anticoagulant for treatment, prophylaxis or otherwise. Therapy with heparin, low molecular weight heparin (LMWH) or fondaparinux is allowed

- Patient who has received radiotherapy ≤ 4 weeks or limited field radiation for palliation ≤ 2 weeks prior to starting study drug, and who has not recovered to grade 1 or better from related side effects of such therapy (exceptions include alopecia) and/or in whom ≥ 25% of the bone marrow (Ellis, 1961) was irradiated
- Patient has had major surgery within 4 weeks prior to starting study drug or has not recovered from major side effects (tumor biopsy is not considered as major surgery)

PRIMARY OBJECTIVE:
I. Determine the maximum tolerated dose (MTD) of tulmimetostat (CPI-0209) administered in combination with carboplatin in platinum-sensitive recurrent ovarian cancer.
SECONDARY OBJECTIVE:
I. To further characterize the safety and efficacy of CPI-0209 in combination with carboplatin in platinum-sensitive recurrent ovarian cancer.
EXPLORATORY OBJECTIVE:
I. To further characterize the efficacy of CPI-0209 in combination with carboplatin in platinum-sensitive recurrent ovarian cancer.
OUTLINE: This is a dose-escalation study of CPI-0209 in combination with carboplatin.
Patients receive CPI-0209 orally (PO) once daily (QD) on days -5 to 21 of cycle 1 and on days 1-21 of remaining cycles and receive carboplatin intravenously (IV) on day 1 of each cycle. Treatment repeats every 21 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Patients who achieve stable disease or better may continue to receive CPI-0209 PO QD on days 1-28 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo blood sample collection, biopsy, and computed tomography (CT), magnetic resonance imaging (MRI) or positron emission tomography (PET) at screening and on study.
After completion of study treatment, patients are followed up at 30 and 60 days and then for up to 2 years.
