About
This phase I trial identifies the best dose, possible benefits and/or side effects of BAY 1895344 in combination with chemotherapy in treating patients with solid tumors or urothelial cancer that has spread to other places in the body (advanced). BAY 1895344 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Cisplatin and gemcitabine are chemotherapy drugs that stop the growth of tumor cells by killing the cells. Combining BAY 1895344 with chemotherapy treatment (cisplatin, or cisplatin and gemcitabine) may be effective for the treatment of advanced solid tumors, including urothelial cancer.
Full description
PRIMARY OBJECTIVES:
I. To establish the safety and tolerability of the combination of cisplatin + elimusertib (BAY 1895344) in patients with advanced solid tumors.
II. To establish the safety and tolerability of the combination of cisplatin + gemcitabine + BAY 1895344 in patients with advanced solid tumors with an emphasis on urothelial carcinoma (UC).
III. To establish the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) of cisplatin + BAY 1895344 and cisplatin + gemcitabine + BAY 1895344.
SECONDARY OBJECTIVES:
I. To evaluate the pharmacokinetic profile of BAY 1895344 (in the doublet and triplet combinations) and gemcitabine (in the triplet) in combination with cisplatin.
II. To further evaluate the toxicity of the combination of cisplatin + gemcitabine + BAY 1895344 in patients with UC.
III. To evaluate preliminary efficacy observed with cisplatin + BAY 1895344 and cisplatin + gemcitabine + BAY 1895344 in patients with advanced solid tumors, including UC.
IV. To monitor for tumor response and symptom relief in addition to safety and tolerability.
V. To evaluate the association between ATM expression by immunohistochemical staining and responses to therapy.
EXPLORATORY OBJECTIVES:
I. To evaluate the correlation of biomarkers, including deleterious deoxyribonucleic acid (DNA) damage response (DDR) gene alterations and circulating tumor (ct)DNA with responses to therapy using whole exome sequencing (WES) and messenger ribonucleic acid sequencing (RNA seq) analysis of archival formalin fixed paraffin embedded (FFPE) tissue, as well as blood.
II. To correlate drug exposure with response and/or toxicity.
OUTLINE: This is a dose-escalation study of elimusertib. Patients are assigned to 1 of 2 arms.
ARM I (DOUBLET COMBINATION): Patients receive cisplatin intravenously (IV) over 1-2 hours on day 1 and 8, and elimusertib orally (PO) once daily (QD) on days 2 and 9. Treatment repeats every 21 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity.
ARM II (TRIPLET COMBINATION): Patients receive cisplatin IV over 1-2 hours on day 1 and 8, gemcitabine IV over 30 minutes on days 1 and 8, and elimusertib PO QD on days 2 and 9. Treatment repeats every 21 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days, then every 3 months thereafter.

- Patients with histologically confirmed advanced or unresectable urothelial carcinoma are eligible
- The histology should be predominantly urothelial (>= 50% of sample evaluated contains urothelial histology)
-
Age >= 18 years. Because no dosing or adverse event data are currently available on the use of BAY 1895344 in combination with gemcitabine and cisplatin in patients < 18 years of age, children are excluded from this study
-
Eastern Cooperative Oncology Group (ECOG) performance status =< 2 (Karnofsky >= 60%)

Availability of archival FFPE tissue
-
Prior cisplatin exposure of < 300 mg/m^2. Patients with prior cisplatin treatment must have received last cisplatin treatment > 6 months prior to enrollment
-
Prior treatment with PARP inhibitors is permitted (such as olaparib, rucaparib, or other experimental inhibitors of PARP administered in a clinical trial)
-
Prior immune checkpoint inhibitor therapy is permitted (including anti-programmed cell death protein 1 [PD-1], anti-PD-ligand [L]1 therapy, such as pembrolizumab, nivolumab, avelumab, durvalumab, atezolizumab, or anti-cytotoxic t-lymphocyte protein 4 [CTLA4] therapy such as ipilimumab, or other experimental immune checkpoint pathway inhibitors administered in a clinical trial)

-
The effects of BAY 1895344, cisplatin, and gemcitabine on the developing human fetus are unknown. For this reason and because deoxyribonucleic acid (DNA)-damage response inhibitors 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
-
Ability to understand and the willingness to sign a written informed consent document
Exclusion criteria
- Life expectancy < 6 weeks by investigator assessment
- Other active malignancy requiring treatment, except for cutaneous malignancies that require resection such as squamous cell carcinoma, basal cell carcinoma, or cutaneous melanoma, and except for prostate cancer if only on androgen deprivation therapy
- Significant peripheral neuropathy (grade 2 or higher by Common Terminology Criteria for Adverse Events [CTCAE])
- Sensorineural hearing loss (grade 2 or higher by CTCAE)
- Must NOT have had prior treatment with ATR inhibitor (prior BAY1895344 or other investigational ATR inhibitors), or current treatment with any other investigational agents
- 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 targeted therapies (such as PARP inhibitors) within 2 weeks prior to entering the study
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to BAY 1895344 or other agents used in study
- 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
- Pregnant women are excluded from this study because BAY 1895344 as a DNA-damage response inhibitor, cisplatin, 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
