Brief Summary:
This phase I trial identifies the best dose, possible benefits and/or side effects of gemcitabine in combination with BAY 1895344 in treating patients with pancreatic, ovarian, and other solid tumors that have spread to other places in the body (advanced). Gemcitabine is a chemotherapy drug that blocks the cell from making DNA and may kill tumor cells. BAY 1895344 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving gemcitabine and BAY 1895344 in combination may shrink or stabilize cancer.

Detailed Description:

PRIMARY OBJECTIVES:

I. Evaluate the safety and tolerability of gemcitabine in combination with elimusertib (BAY 1895344), as assessed by Common Terminology Criteria for Adverse Events (CTCAE) 5.0. (Dose Escalation and Expansion Cohort) II. Determine the maximum tolerated dose (MTD) of gemcitabine in combination with BAY 1895344. (Dose Escalation Cohort)

SECONDARY OBJECTIVES:

I. To observe and record anti-tumor activity. II. Analyze the pharmacokinetic (PK) profile of the gemcitabine and BAY 1895344 combination.

III. Assessing whether immunohistochemical markers of deoxyribonucleic acid (DNA) damage, gamma-H2AX and phosphorylated (p)NBS1, increase in on-treatment biopsies compared to the levels seen in pre-treatment biopsies.

EXPLORATORY OBJECTIVES:

I. Explore biomarkers that predict response to this combination. II. Evaluate mechanisms of acquired resistance to this combination.

OUTLINE: This is a dose-escalation study of gemcitabine followed by a dose expansion study.

Patients receive gemcitabine intravenously (IV) over 30 minutes on days 1 and 8 and BAY 1895344 orally (PO) once daily (QD) or twice daily (BID) on days 2-3 and 9-10. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 30 days.

Primary Outcome Measures :
  1. Incidence of adverse events [ Time Frame: Up to 1 year ]
    The toxicity of the combination of gemcitabine plus BAY1895344 will be assessed with Common Terminology Criteria for Adverse Events (CTCAE) v. 5.0 criteria.

  2. Maximum tolerated dose (MTD) [ Time Frame: Up to completion of dose-escalation phase ]
    A conventional algorithm (3+3 design) will be used to identify the MTD, escalating on zero of three or one of six dose-limiting toxicities (DLTs), and de-escalating if two DLTs are encountered. The MTD will be the highest dose level at which zero of three or one of six subjects experience a DLT.

  3. Overall response rate (ORR) (expansion cohort) [ Time Frame: Up to 1 year ]
    Radiological response will be assessed with Response Evaluation Criteria in Solid Tumors 1.1 criteria and will be graded as complete response (CR), partial response (PR), stable disease and progressive disease.

  4. Duration of response (expansion cohort) [ Time Frame: Time at which measurement criteria are met for CR or PR (whichever is first recorded) until the first date on which recurrent or progressive disease is objectively documented, assessed up to 1 year ]
  5. Progression free survival (PFS) (expansion cohort) [ Time Frame: Time from study enrollment until the identification of disease progression or death, assessed up to 1 year ]
  6. Overall survival (expansion cohort) [ Time Frame: Time from study enrollment until death due to any cause, assessed up to 1 year ]

Secondary Outcome Measures :
  1. Pharmacokinetic (PK) profile of BAY1895344 in combination with gemcitabine [ Time Frame: Day 1 of dose-escalation phase ]
    Individual PK parameters will be estimated for the maximum concentration (Cmax), area under the concentration-time curve (AUC), half-life (t1/2), apparent clearance (Cl/F) and apparent volume of distribution (V/F), as feasible with non-compartmental methods. The PK variables will be tabulated, and descriptive statistics (e.g., geometric means and coefficients of variation) will be calculated for each dose level. PK parameters will be reported descriptively.

  2. Gemcitabine pharmacokinetics [ Time Frame: Days 1 and 8 of dose-escalation ]
    The CDA phenotype will be correlated with gemcitabine half-life, AUC and the dFdU/gemcitabine metabolic ratio.

  3. Presence or absence of homologous recombination (HR) repair proficiency [ Time Frame: Pre-treatment to time of disease progression, assessed up to 1 year ]
    Will be defined according to formation of RAD51 foci. Will also be evaluated in relation to the clinical outcomes of ORR and PFS time.

  4. Presence or absence of replication stress [ Time Frame: Pre-treatment to time of disease progression, assessed up to 1 year ]
    Will be defined at the gene expression and protein levels for phosphorylated (p)KAP1, pRPA32, cyclin E and MYC. Will also be evaluated in relation to the clinical outcomes of ORR and PFS time.

  5. Presence or absence of ATR activation [ Time Frame: Pre-treatment to time of disease progression, assessed up to 1 year ]
    Will be defined by the expression of pATR and pCHK1. Will also be evaluated in relation to the clinical outcomes of ORR and PFS time.

  6. Conversion of cancer with stable replication forks to one with unstable replication forks [ Time Frame: Pre-treatment to time of disease progression, assessed up to 1 year ]
    DNA fiber assays will be used to assess whether gemcitabine/BAY1895344 treatment converts a cancer with stable replication forks to one with unstable replication forks. Will also be evaluated in relation to the clinical outcomes of ORR and PFS time.

  7. Increase in deoxyribonucleic acid (DNA) damage level (expansion cohort) [ Time Frame: Pre-treatment and on-treatment ]
    Changes in immunohistochemical markers of DNA damage, gamma-H2AX and phosphorylated (p)NBS1.


Other Outcome Measures:
  1. Pharmacodynamic (biological endpoints, toxicity and efficacy) parameters [ Time Frame: Up to 30 days ]
    Will be analyzed with nonparametric statistics.

  • The effects of BAY 1895344 on the developing human fetus are unknown. For this reason and because DNA-damage response inhibitor agents 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

  • 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 including but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, clinically significant cardiac arrhythmia, uncontrolled major seizure disorder, unstable spinal cord compression, superior vena cava syndrome or psychiatric illness/social situations that would limit compliance with study requirements are excluded
  • Patients with psychiatric illness/social situations that would limit compliance with study requirements
  • Pregnant women are excluded from this study because BAY 1895344 as a DNA-damage response inhibitor, and gemcitabine 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 have successfully undergone treatment for another, unrelated clinically relevant cancer, >= 3 years post final treatment, are eligible to participate in this study

  • Patients not able to swallow tablets
