- Pregnant and breastfeeding women are excluded from this study because ZEN003694 has the potential for teratogenic or abortifacient effects and M1774 is genotoxic in in vivo nonclinical studies. Patients who discontinue breastfeeding are eligible for enrollment and may not resume breastfeeding until 1 month off treatment.
- Patients receiving any medications or substances that are strong inhibitors or inducers of CYP3A4 are ineligible. Strong inhibitors or inducers of CYP3A4 must be discontinued at least 7 days prior to the first dose of ZEN003694. Moderate inhibitors of CYP3A4 should be avoided. If alternative is not available, the use of moderate CYP3A4 inhibitors is permitted with careful monitoring and approval by study team. At the discretion of the provider, additional monitoring (labs, toxicity checks) may be implemented for use of moderate CYP3A4 inhibitors. Substrates of CYP1A2 with narrow therapeutic window also must be avoided white taking ZEN003694. 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 receiving any medications or substances that are Factor Xa inhibitors are discouraged given concerns for thrombocytopenia (i.e., rivaroxaban, apixaban, betrixaban, edoxaban otamixaban, letaxaban, eribaxaban) and Factor IIa inhibitors (i.e., dabigatran). Low molecular weight heparin is allowed. If patients are not willing to switch to low molecular heparin, they must obtain approval by study team.
- Serious gastrointestinal bleeding within 3 months, refractory nausea and vomiting, uncontrolled diarrhea, known malabsorption, significant small bowel resection or gastric bypass surgery, use of feeding tubes, presence of drainage gastrostomy tube, other chronic gastrointestinal disease, and/or other situations that may preclude absorption of oral medications M1774 and/or ZEN003694.

About this study
Official title: A Phase 1B Study of Combination ATR (M1774) and BET Inhibition (ZEN003694) to Exploit ARID1A Loss in Recurrent Ovarian and Endometrial Cancer
This phase Ib trial tests the safety, side effects, and best dose of M1774 when given with ZEN-3694 in treating patients with ovarian and endometrial cancer that has come back (recurrent). M1774 and ZEN-3694 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. M1774 and ZEN-3694 combined together has demonstrated to be better than either drug alone in killing ovarian tumor cells.
Read the detailed description
PRIMARY OBJECTIVES:
- To determine the maximum tolerated dose (MTD) and the dose-limiting toxicities (DLTs) for combination of tuvusertib (ATR inhibitor [M1774]) and BET bromodomain inhibitor ZEN-3694 (BET inhibitor [ZEN003694]) in women with recurrent clear cell, endometrioid, and platinum resistant high grade serous ovarian carcinoma (HGSOC) and clear cell and endometrioid endometrial carcinoma irrespective of ARID1A status (PART I).
II. To determine safety and tolerability in ARID1A pathogenic alteration (ARID1A^MUTATION [MUT]) and ARID1A wildtype (ARID1A^WT) cohorts (ARID1A is an integral biomarker) in an expansion phase (PART II).
III. To determine change in pharmacodynamic biomarker expression of gammaH2AX (for ATR inhibition, integral biomarker) from pre-treatment and on-treatment tumor samples in ARID1A^MUT and ARID1A^WT expansion cohorts by immunohistochemistry (IHC) (PART II).
SECONDARY OBJECTIVES:
- To evaluate change in pharmacodynamic biomarker expression of cmyc (for BET inhibition, integrated biomarker) from pre-treatment and on-treatment tumor samples in ARID1A^MUT and ARID1A^WT expansion cohorts by Digital Spatial Profiling (DSP) (PART II).
II. To evaluate change in pharmacodynamic biomarker expression of gammaH2AX (for ATR inhibition, integrated biomarker) from pre-treatment and on-treatment tumor samples in ARID1A^MUT and ARID1A^WT expansion cohorts by DSP (PART II).
III. To investigate if ARID1A protein by IHC and DSP correlates with ARID1A pathogenic alteration in pre-treatment tumor biopsy samples (PART II).
IV. To estimate objective response rate (ORR) and progression free survival (PFS) at 6 months in ARID1A pathogenic alteration and wildtype cohorts (PART II).
EXPLORATORY OBJECTIVES:
- To evaluate the pharmacokinetics of ZEN003694 and its active metabolite, ZEN003791, when the drug is taken alone and in combination with M1774, as well as M1774 pharmacokinetics in the combination (PART I).
II. To assess if ARID1A pathogenic alteration status by Next Generation Sequencing (NGS) correlates with ARID1A protein by IHC utilizing existing archival tissue and evaluate retrospectively (PART I).
III. To evaluate objective response rate (ORR) and progression free survival (PFS) at 6 months and to evaluate if these correlate with ARID1A pathogenic alteration status by Next Generation Sequencing (NGS) and with ARID1A protein by IHC (PART I).
IV. In patients with prior somatic tumor testing by Next Generation Sequencing, will obtain results and correlate molecular profiles (i.e., ARID1A pathogenic alteration, PIK3CA pathogenic alteration, C-myc amplification, ATM pathogenic alteration) with response by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 or CA-125 by Gynecological Cancer Intergroup (GCIG) (Rustin et al., 2011) (PART I).
- To evaluate the pharmacokinetics of ZEN003694 and its active metabolite, ZEN003791, when the drug is taken alone and in combination with M1774, as well as M1774 pharmacokinetics in the combination (PART II).
VI. To assess if there is a greater overall response by RECIST 1.1 and CA-125 by GCIG (Rustin et al. 2011) in ARID1A pathogenic alteration cohort (ARID1A^MUT ) compared to ARID1A wildtype (ARID1A^WT ) cohort (PART II).
VII. To correlate pharmacodynamics and pharmacokinetics in ARID1A^MUT and ARID1A^WT expansion cohorts at the MTD (determine if drug levels affect drug target engagement and expression (e.g., gamma [g]H2AX and MYC)) (PART II).
VIII. To estimate overall survival (OS) in ARID1A pathogenic alteration versus (vs) wildtype cohorts (PART II).
IX. To identify biomarkers of response we will correlate ORR and PFS with ARID1A gene alteration, ARID1A protein level (IHC and DSP), gammaH2AX (IHC and DSP), C-myc (DSP), and total (tot) ATM (DSP), and HEXIM1 by ribonucleic acid (RNA) sequencing (Seq) in tumor biopsies (PART II).
- To explore if liquid biopsies are a good surrogate for tumor ARID1A pathogenic alteration (PART II).
XI. To evaluate if ARID1A expression changes over time, we will compare ARID1A expression by NGS (gene alteration) and IHC (protein) using existing archival tumor to most recent pre-treatment biopsy samples required for PART II expansion cohort (PART II).
OUTLINE: This is a dose-escalation study of tuvusertib followed by a dose-expansion study.
Patients receive tuvusertib orally (PO) once daily (QD) either on days 2-14 of cycle 1 and days 1-14 of subsequent cycles or days 1-14 of each cycle and BET bromodomain inhibitor ZEN-3694 PO QD on days 1-28 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients in the dose-escalation phase of the trial also undergo collection of blood samples on study, and x-ray, computed tomography (CT), or magnetic resonance imaging (MRI) throughout the trial. Patients in the dose-expansion phase of the trial also undergo biopsies during screening and on study, and x-ray, CT, or MRI, and collection of blood samples throughout the trial.
After study completion, patients are followed every 3 months for 2 years and then every 6 months for 3 years, or until the study is terminated.

What is being measured
The primary outcome is the main question the study is designed to answer.
Dose-limiting toxicities (DLTs) (Part I)
DLT is defined as any adverse events considered possibly, probably or definitely related to study drug combination as evaluated by National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version (v)5.0. A Bayesian Optimal Interval (BOIN) design will be used to determine the MTD (Yuan et al. 2016). Will be summarized by dose level.
Measured: Within the first cycle of study treatment (up to 28 days)
DLTs (Part II)
DLT is defined as any adverse events considered possibly, probably or definitely related to study drug combination as evaluated by NCI CTCAE v5.0. Within the ARID1A cohorts, the number of patients with DLTs will be summarized, and adverse events tabulated using the highest observed grade for each system organ class or preferred term, using CTCAE v5.0 criteria by cohort.
Measured: Within the first 2 cycles of study treatment (up to 56 days)
Measurements for gammaH2AX (PART II)
GammaH2AX will be assessed by immunohistochemistry (IHC) from tumor samples. Will be summarized using descriptive statistics (e.g., mean, standard deviation, median) by cohort and collection time point. One-sided Wilcoxon signed rank tests will be used for testing whether there is a change in gammaH2AX expression in the pre-treatment vs on-treatment tumor in the patients who have been treated at the recommended phase 2 dose (RP2D) and have evaluable bio-specimen by cohort, respectively.
Measured: Baseline and cycle 1, day 8 (C1D8)
Incidence of adverse events (Part I and II)
The frequency and severity of adverse events will be assessed by CTCAE v5.
Measured: Up to 5 years
Secondary outcomes (5)
Measurements for c-myc (Part II)
Will be assessed by Digital Spatial Profiling (DSP) using tumor samples. Will be summarized using descriptive statistics (e.g., mean, standard deviation, median) by cohort, biospecimen type, and collection time point. One-sided Wilcoxon signed rank tests will be applied to examine whether there is a change in c-myc expression in the pre-treatment vs on-treatment tumor in the patients who have been treated at the RP2D and have evaluable bio-specimen by cohort, respectively.
Measured: Baseline and C1D8
Measurements for gammaH2AX (Part II)
Will be assessed by DSP using tumor samples. Analyses will be performed in similar approach to the primary endpoint gammaH2AX expression by IHC.
Measured: Baseline and C1D8
Measurements for ARID1A protein and pathogenic alteration status (Part II)
Summary statistics (e.g., mean and standard deviation, median) for ARID1A protein by IHC and DSP in pre-treatment tumor will be provided for the 12-point score (measure of ARID1A positive staining cells by IHC) by cohort and mutation status (Khalique et al, 2018). ARID1A pathogenic alteration means there is loss of ARID1A protein as assessed by IHC and DSP. ARID1A wildtype means there is no mutation and ARID1A protein is present. The relationship between ARID1A protein and ARID1A pathogenic alteration status will be investigated by Wilcoxon rank-sum test.
Measured: Baseline, C1D8, and at progression
Objective response rate (Part II)
Objective response rate (ORR) is defined as the binomial proportion of evaluable patients with best overall response assessed by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 of complete or partial response (CR or PR).
Measured: At 6 months
Progression-free survival (Part II)
Progression-free survival at six months (PFS) is defined as the binomial proportion of evaluable patients who survive without documentation of disease progression (RECIST 1.1) at least 6 months after starting study entry.
Measured: From study entry to time of progression or death, whichever occurs first, or date of last contact if neither progression nor death has occurred, assessed at 6 months
