Clinical Trial Summary

This phase I trial investigates the best dose, possible benefits and/or side effects of BAY 1895344 in combination with FOLFIRI in treating patients with stomach or intestinal cancer that that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) or has spread from where it first started (primary site) to other places in the body (metastatic). BAY 1895344 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as irinotecan, fluorouracil, and leucovorin, (called FOLFIRI in short) 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 BAY 1895344 in combination with FOLFIRI may help shrink advanced or metastatic stomach and/or intestinal cancer.

Description:

PRIMARY OBJECTIVE:

I. Determine the safety and maximum tolerated dose (MTD) of elimusertib (BAY 1895344) with leucovorin calcium, fluorouracil, and irinotecan hydrochloride (FOLFIRI).

SECONDARY OBJECTIVES:

I. To observe and record anti-tumor activity by overall response rate (ORR), progression-free survival (PFS), and overall survival (OS).

II. Determine the response and clinical benefit rate (complete response + partial response + stable disease) of BAY 1895344 with FOLFIRI in colorectal and gastric/gastroesophageal cancers.

III. Evaluate tumor and peripheral blood mononuclear cell (PBMC) deoxyribonucleic acid (DNA) damage signaling in the context of the chemotherapy backbone alone and when combined with BAY 1895344.

IV. Evaluate the pharmacokinetics (PK) profile of fluorouracil (5-FU) and irinotecan.

V. Evaluate the PK profile of BAY 1895344. VI. Evaluate the relationship between ATM status by immunohistochemistry (IHC) and clinical efficacy of the BAY 1895344/FOLFIRI combination.

EXPLORATORY OBJECTIVES:

I. Evaluate the exposure-response relationship between drug exposures and toxicity and response, and UGT1A1 genotype.

II. Evaluate the relationship between tumor mutations and clinical efficacy of the BAY 1895344/FOLFIRI combination.

OUTLINE: This is a dose-escalation study of elimusertib, irinotecan, and fluorouracil with fixed-dose leucovorin followed by a dose-expansion study.

Patients receive elimusertib orally (PO) once daily (QD) on days 2, 3, 16, and 17 and irinotecan hydrochloride intravenously (IV) over 90 minutes, fluorouracil IV over 46 hours, and leucovorin calcium IV on days 1 and 15. Cycles repeat every 28 day in the absence of disease progression or unacceptable toxicity. Patients undergo tumor biopsy during screening and on study and blood sample collection and imaging throughout the study.

After completion of study treatment, patients are followed up for 30 days and then every 3 months for up to 1 year or until their disease gets worse or they begin a new treatment for their cancer.

To be eligible for this trial, patients should be class 2B or better

• The effects of BAY 1895344 on the developing human fetus are unknown. For this reason and because DNA-damage response inhibitors agents as well as other therapeutic agents used in this trial, 5-FU and irinotecan, are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation and for 6 months after completion of BAY 1895344 administration

• Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 6 months after completion of study treatment administration

• Ability to understand and the willingness to sign a written informed consent document. Participants with impaired decision-making capacity (IDMC) who have a legally-authorized representative (LAR) and/or family member available will also be eligible

Exclusion Criteria:

• Patients with a history of prior treatment with an ATR inhibitor

• Patients with a history of other malignancy that could affect compliance with the protocol or interpretation of the results

• Patients who have had chemotherapy or radiotherapy within 3 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study

• Patients who have not recovered from adverse events due to prior anti-cancer therapy (i.e., have residual toxicities > grade 1) with the exception of alopecia

• Patients who are receiving any other investigational agents

• History of hypersensitivity or allergic reactions attributed to compounds of similar chemical or biologic composition to BAY 1895344, 5-FU, leucovorin, or irinotecan. Patient eligibility can be discussed with the primary investigator (PI) if prior reactions do not seem to warrant excluding the patient

• Patients receiving any medications that are substrates of CYP3A4 with a narrow therapeutic window or strong inhibitors/inducers of CYP3A4 are ineligible, if they cannot be transferred to alternative medication. 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 uncontrolled intercurrent illness

• Patients with psychiatric illness/social situations that would limit compliance with study requirements

• Gastrointestinal pathology or history that adversely impact the ability to take or absorb oral medication

• Pregnant women are excluded from this study because BAY 1895344 as a DNA-damage response inhibitor may have the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with BAY 1895344 breastfeeding should be discontinued if the mother is treated with BAY 1895344 and for 4 months after end of treatment. These potential risks may also apply to other agents used in this study

• Patients who were unable to tolerate prior irinotecan treatment are excluded from this study

• Patients with a corrected QT (QTc) interval >= 470 msec are excluded from this study

Other	Incidence of adverse events	Logistic regression and proportional hazards (Cox) regression will be used to assess the relationships between exposure and response and toxicity; exposure-response will be assessed within disease cohorts of sufficient size, while exposure-toxicity will pool all patients. All patients will be used for the E-R analyses. Advanced population PK methods may be employed at a later stage to assess the link between drug exposure and biological effects and efficacy.	Up to 1 year post treatment
Other	Status of deoxyribonucleic acid damage repair (DDR) genes	Assessed by whole exome sequencing and ribonucleic acid sequencing. The efficacy analyses will be repeated by DDR tumor mutation status, but these analyses will have limited sample sizes and will not be adequately powered for statistical comparisons.	Up to 1 year post treatment
Primary	Maximum tolerated dose (MTD) of elimusertib (BAY 1895344) in combination with irinotecan, fluorouracil, and leucovorin (FOLFIRI)	A BOIN - Bayesian Optimal intervals trial design will be used to determine the MTD.	Up to 28 days
Secondary	Overall response rate	Assessed per Response Evaluation Criteria in Solid Tumors. The probability of clinical response (complete response [CR]+partial response [PR]) and disease control (CR+PR+stable disease) will be estimated within the disease cohorts, with consideration of previous irinotecan exposure, with exact 95% binomial confidence intervals.	Up to 1 year post treatment
Secondary	Progression-free survival (PFS)	PFS will be estimated within disease cohorts by the product-limit (Kaplan-Meier) estimator, along with 95% confidence regions.	From start of treatment to time of progression or death, whichever occurs first, assessed up to 1 year
Secondary	Overall survival (OS)	OS will be estimated within disease cohorts by the product-limit (Kaplan-Meier) estimator, along with 95% confidence regions.	Up to 1 year post treatment
Secondary	Peripheral blood mononuclear cell gammaH2AX and p-ATM signaling	Signaling during the pharmacokinetics (PK) lead-in and in combination with BAY 1895344 will be compared with a non-parametric paired test (e.g. Wilcoxon rank test), at a significance level at p < 0.05. For tumors, this will be performed only for patients in the dose expansion cohorts.	Up to 1 year post treatment
Secondary	Tumor multiplex incomplete Freund's adjuvant signaling	Signaling during the PK lead-in and in combination with BAY 1895344 will be compared with a non-parametric paired test (e.g. Wilcoxon rank test), at a significance level at p < 0.05. For tumors, this will be performed only for patients in the dose expansion cohorts.	Up to 1 year post treatment
Secondary	Area under curve (AUC) and concentration maximum (Cmax) of irinotecan and 5-FU	PK during the PK lead-in and in combination with BAY 1895344 will be compared with a non-parametric paired test, at a significance level at p < 0.05.	Up to 1 year post treatment
Secondary	AUC and Cmax of BAY 1895344	PK of BAY 1895344 in combination with irinotecan and fluorouracil will be compared with historical controls in an exploratory fashion.	Up to 1 year post treatment
Secondary	ATM status	Will be assessed by immunohistochemistry (IHC) and PFS. The association between ATM and responses will be described, with a table outlining patients who achieved progressive disease, stable disease, partial or complete responses and whether they exhibited ATM expression by IHC or not.	Up to 1 year post treatment
