Part A: Patients with histologically confirmed solid tumors or NHL. Patients with tumors known to be positive for DDR defects (such as ataxia-telangiectasia mutated [ATM] deleterious mutation or low ATM expression) can be included.
J-arm: Patients with histologically confirmed solid tumors. Patients with tumors known to be positive for DDR defects (such ATM deleterious mutation or low ATM expression) can be included.
Part A.1: Patients with histologically confirmed solid tumors or NHL with ATM loss and/or ATM deleterious mutations
Part B: - Patients with DDR deficiency biomarker positive advanced solid tumors of the following histologies:
i) castration-resistant prostate cancer;
ii) HER2-negative BC that is hormone-receptor positive (estrogen-receptor positive, progesterone-receptor positive, or both) or TNBC;
iii) colorectal cancer;
iv) gynecological tumors (ovarian, primary peritoneal, and fallopian tube cancers, endometrial cancer, or cervical cancer);
v) Patients with histologically confirmed advanced cancer and loss of ATM protein by IHC (immunohistochemistry), regardless of the cancer type.
The biomarker status of patients in Part B will be evaluated before general screening and only patients with the presence of the putative biomarkers of DDR deficiency will be recruited into general screening.
The following inclusion criteria apply to ALL (dose-escalation and expansion) patients:
1. Ability to understand and the willingness to sign a written IC, obtained before any study specific procedures are performed.
2. Patients with tumors resistant or refractory to standard treatment and in which, in the opinion of the investigator, experimental treatment with BAY 1895344 may be of benefit. Furthermore, no standard therapy would confer clinical benefit.
3. Male or female patients aged =18 years; = 20 years age for Japanese patients
4. Patients must have measurable disease (as per Response Evaluation Criteria in Solid Tumors, version 1.1 [RECIST 1.1] or the Lugano classification, as applicable with the exception of prostate cancer patients who must have measurable or evaluable disease per the recommendations of the PCWG3).
5. ECOG performance status of 0 to 1
6. Life expectancy of at least 12 weeks
7. Patients must have adequate bone marrow function as assessed by the following laboratory tests to be conducted within 7 (+2) days before the first dose of study drug:
a. Hemoglobin =9 g/dL
b. Absolute neutrophil count =1.5 x 10E9/L (=1500/mm3)
c. Platelet count =100 x 10E9/L (=100,000/mm3)
8. Patients must have adequate liver function as assessed by the following laboratory tests to be conducted within 7 (+2) days before the first dose of study drug:
a. Total bilirubin =1.5 times the upper limit of normal (ULN)
b. ALT+AST =3 times ULN or =5 times ULN for patients with malignant liver involvement
9. Patients must have adequate kidney function, as assessed by the estimated glomerular filtration rate (eGFR) >40 mL/min per 1.73 m2 within 7 (+2) days before the first dose of study drug; eGFR is to be calculated by the MDRD formula.
10. Patients must have adequate coagulation, as assessed by the following laboratory tests to be conducted within 7 (+2) days before the first dose of study drug:
a. International normalized ratio =1.5 and prothrombin time =1.5 times ULN for patients not on anticoagulation
b. Activated partial thromboplastin time =1.5 times ULN for patients not on anticoagulation
11. Adequate cardiac function per institutional normal
The following exclusion criteria apply to ALL (dose-escalation and expansion) patients:
1. Known hypersensitivity to the study drugs or excipients of the preparations or any agent given in association with this study
2. History of cardiac disease: congestive heart failure NYHA class > II, unstable angina (angina symptoms at rest), new-onset angina (within the past 6 months before study entry), myocardial infarction within the past 6 months before study entry, or cardiac arrhythmias requiring antiarrhythmic therapy (beta blockers, calcium channel blockers, and digoxin are permitted)
3. Uncontrolled arterial hypertension despite optimal medical management
4. Moderate or severe hepatic impairment, i.e. Child-Pugh class B or C
5. Patients with known HIV infection
6. Patients who have an active HBV or HCV infection requiring treatment. Patients with chronic HBV or HCV infection are eligible at the investigator's discretion provided that the disease is stable and
sufficiently controlled under treatment.
7. Infections of CTCAE Grade 2 not responding to therapy or active clinically serious infections of CTCAE Grade >2
8. Metastatic brain, spinal or meningeal tumors unless the Patient is >3 months from definitive therapy, has a stable imaging study within 4 weeks prior to the first dose of study drug and is clinically stable with respect to the tumor at the time of study entry. Patients with asymptomatic brain metastases must not be on steroid therapy. Patients with neurological symptoms should undergo a CT / MRI scan of the brain or spinal column to exclude new or progressive brain, meningeal or spinal metastases. Patients must not be undergoing acute steroid therapy or tapering steroids (chronic steroid therapy is acceptable if the dose is stable for at least 1 month before and following screening radiographic studies).
9. Uncontrolled seizure disorder requiring therapy (e.g. strong CYP3A4 inducers such as carbamazepine and phenytoin)
10. History of organ allograft transplantation
11. Evidence or history of bleeding disorder, i.e. any hemorrhage / bleeding event of CTCAE Grade >2 within 4 weeks before the first dose of study drug
12. Serious, non-healing wound, ulcer, or bone fracture
13. Previous or concurrent cancer that is distinct in primary site or histology from the cancer being evaluated in this study, with the exception of the following previous or concurrent cancer types:
a. Curative treatment for localized cancer completed without signs of recurrence and treatment-related toxicity and low risk of recurrence as assessed by the investigator,
b. In-situ prostate cancer, Gleason Score <7, prostate-specific Antigen <10 ng/mL (very low risk and low risk, according to therapy guidelines; active surveillance / observation is a recommended option).
14. Any clinical condition that is considered unstable or might jeopardize the safety of the patient and his / her compliance in the study
15. Inability to swallow oral medications
16. Any malabsorption condition
17. Breastfeeding. Female patients must not breastfeed during treatment and until 4 months after last study drug administration in Part A, J-arm.
18. Treatment with anticancer chemotherapy or immunotherapy during the study or within 3 weeks before the first dose of study drug. For small-molecule drugs, a period of at least 3 half-lives before the first dose of study drug is acceptable. Mitomycin C or nitrosoureas should not be given within 6 weeks before the first dose of study drug.
