Clinical Trial Summary

This phase I trial investigates the side effects and best dose of BAY 1895344 when given together with usual chemotherapy (irinotecan or topotecan) in treating patients with solid tumors that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced), with a specific focus on small cell lung cancer, poorly differentiated neuroendocrine cancer, and pancreatic cancer. BAY 1895344 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as irinotecan and topotecan, 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. Adding BAY 1895344 to irinotecan or topotecan may help to slow the growth of tumors for longer than seen with those drugs alone.

Description:

PRIMARY OBJECTIVES: I. To assess safety and tolerability of each of the elimusertib (BAY 1895344) plus topoisomerase 1 (top1) inhibitor (irinotecan hydrochloride [irinotecan] or topotecan hydrochloride [topotecan]) combinations. II. To estimate maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) of each of the combinations. SECONDARY OBJECTIVES: I. To observe and record anti-tumor activity. II. To estimate objective response rate (ORR), progression free survival (PFS), overall survival (OS) and duration of response (DOR) in patients treated with each combination. III. To estimate plasma pharmacokinetic (PK) characteristics of BAY 1895344 plus each top1 inhibitor (irinotecan or topotecan) when used in combination. IV. To estimate changes in pharmacodynamic (PD) markers of deoxyribonucleic acid (DNA) damage (gamma-H2AX, phosphorylated [p]S343-NBS1) elicited by each combination from on-treatment tumor biopsies (in dose expansion cohorts only). EXPLORATORY OBJECTIVES: I. To estimate response outcomes (ORR, PFS, OS, DOR) in study patients by tumor ataxia telangiectasia mutated (ATM) expression loss (assessed by immunohistochemistry [IHC]). II. To estimate response outcomes (ORR, PFS, OS, DOR) in study patients with tumor DNA damage response (DDR) mutations (assessed by whole exome sequencing [WES], ribonucleic acid [RNA] sequencing [RNA Seq], and circulating tumor DNA [ctDNA] analysis). OUTLINE: This is a dose-escalation study. Patients are assigned to 1 of 3 cohorts. COHORT I: Patients receive elimusertib orally (PO) twice daily (BID) on days 1 and 2 and irinotecan intravenously (IV) over 90 minutes on day 1 of each cycle. Cycles repeat every 14 days in the absence of disease progression or unacceptable toxicity. Patients undergo computed tomography (CT) and/or magnetic resonance imaging (MRI) throughout the study, tumor biopsy at screening and on study, and collection of blood samples at screening. COHORT II: Patients receive elimusertib PO once daily (QD) on days 2, 3, 9, 10, 16, and 17 of cycle 1 and 2, and on days 2, 3, 9, and 10 of each cycle thereafter. Patients receive irinotecan IV over 90 minutes on days 1, 8, and 15 of cycle 1 and 2, and on days 1 and 8 of each cycle thereafter. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. Patients undergo CT and/or MRI throughout the study, tumor biopsy at screening and on study, and collection of blood samples at screening. COHORT III: Patients receive elimusertib PO QD on days 2 and 5 and topotecan IV over 30 minutes on days 1-5 of each cycle. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. Patients undergo CT and/or MRI throughout the study, tumor biopsy at screening and on study, and collection of blood samples at screening. After completion of study treatment, patients are followed every 2 months for up to 6 months.

• Patients with known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function using the New York Heart Association Functional Classification. 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 as well as other therapeutic agents used in this trial 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 BAY 1895344 administration
• Patient must have the 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 who have previously been treated with irinotecan will not be eligible to participate in the irinotecan arm and patients who have previously been treated with topotecan will not be eligible to participate in the topotecan arm. However, patients who previously received irinotecan may be treated with topotecan (and vice versa) should the other agent be considered a possible standard of care for their disease. Patients who have previously been treated with BAY 1895344 will be excluded from the study
• Patients who have had chemotherapy or radiotherapy within 4 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 and endocrinopathies from prior immunotherapy

• Patients receiving any medications or substances 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
• Pregnant women are excluded from this study because BAY 1895344 is agent with 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. These potential risks may also apply to other agents used in this study
• Patients with an uncontrolled infection requiring IV antibiotics will not be eligible to participate in the study
• Patients on strong CYP3A4 inhibitors must discontinue them at least 1 week prior to starting irinotecan therapy
