About
Researchers are looking for a better way to treat people who have advanced non-small cell lung cancer (NSCLC), a group of lung cancers that have spread to nearby tissues or to other parts of the body.
Epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor 2 (HER2) are proteins that help cells to grow and divide. A damage (also called mutation) to the building plans (genes) for these proteins in cancer cells leads to a production of abnormal EGFR and/or HER2. These abnormal proteins drive the growth and the spread of the cancer. Several EGFR and/or HER2 mutations exist in the cancer cells. The study treatment, BAY2927088, is expected to block the mutated EGFR and HER2 proteins which may stop the spread of NSCLC.
The main purpose of this study is to learn:
Escalation, Backfill, and Expansion Part:
For this, the researchers will measure the followings:
For this, the researchers will measure the following:
• Percentage of participants whose cancer completely disappears (complete response) or reduces by at least 30% (partial response) after taking the treatment (also known as objective response rate (ORR)). This will be assessed by doctors other than the study doctor.
This study has 4 parts:
The participants in this study will take the study treatment BAY2927088 in 3-week periods called "cycles". They will in general take BAY2927088 once or twice daily as a liquid/tablet by mouth until their cancer gets worse, they have medical problems, they leave the study, or the study is terminated. Participants will have no more than 5 visits per cycle.
During the study, the study team will:
An adverse event is considered "serious" when it leads to death, puts the participant's life at risk, requires hospitalization, causes disability, causes a baby being born with medical problems, or is medically important.

Inclusion criteria
Note: Except for participants eligible for one of the groups (Expansion or Extension) who should have received no prior systemic treatment for locally advanced or metastatic disease.
Adequate archival tumor tissue (ideally taken after last targeted treatment and not older than 6 months) has to be available, either from primary or metastatic sites. If archival material is not available, a fresh tumor biopsy should be performed if feasible and if the procedure poses no significant risk for the participant.
Measurable disease by RECIST v1.1 with at least one lesion not chosen for biopsy during the screening period (if a biopsy is taken during screening) that can be accurately measured at baseline with computed tomography (CT) or magnetic resonance imaging (MRI) and that is suitable for accurate repeated measurements. A biopsied lesion should not be used as a target lesion for RECIST 1.1 tumor assessments (or, for participants in Expansion Group G, for RANO-BM tumor assessments). Previously irradiated lesions must have shown progression to be considered measurable.
Documented activating EGFR and/or HER2 mutation assessed by a Clinical Laboratory Improvement Amendments (CLIA)-certified (United States [US] sites) or an equally accredited (outside of the US) local laboratory
Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1.
Minimum life expectancy of 12 weeks.
Adequate bone marrow function as assessed by the following laboratory tests to be conducted within 7 days before the first dose of study treatment:
Adequate kidney function as assessed by following laboratory test to be conducted within 7 days before the first dose of study treatment:
a. Estimated glomerular filtration rate (eGFR) > 50 mL/min per 1.73 m^2 according to the Modification of Diet in renal Disease Study Group (MDRD) formula.
Adequate liver function as assessed by following laboratory tests to be conducted within 7 days before the first dose of study treatment:
Exclusion criteria
Treatment with an EGFR tyrosine kinase inhibitor (TKI) ≤ 8 days or 5x the terminal phase, elimination half-lives, whichever is shorter, prior to the first dose of study drug.
Treatment with a systemic anti-cancer treatment (excluding EGFR TKIs as described above) ≤ 14 days prior to the first dose of study drug.
Radiation therapy, stereotactic radiosurgery (SRS) and palliative radiation ≤ 14 days prior to the first dose of study drug.
Treatment with immunotherapy ≤ 28 days prior to the first dose of study drug.
Have any unresolved toxicity of Grade ≥ 2 from previous anti-cancer treatment, except for alopecia and skin pigmentation. Participants with chronic, but stable Grade 2 toxicities may be allowed to enroll after agreement between the Investigator and Sponsor.
Any history of primary brain or leptomeningeal disease (symptomatic or asymptomatic), presence of symptomatic central nervous system (CNS) metastases, or CNS metastases that require local treatment (such as radiotherapy or surgery).
History of spinal cord compression or brain metastases with the following exceptions:
Participants with treated brain metastases that are asymptomatic at screening and who are off or receiving low-dose corticosteroids (≤10 mg prednisone or equivalent) for at least 7 days prior to first dose of BAY 2927088 are eligible to enroll in Dose Escalation and Backfill.
Participants with treated brain metastases that are asymptomatic at screening are eligible in Dose Expansion/Extension (with the exception of Group G) if all of the following criteria are met:
Participants with history of spinal cord compression >3 months from definitive therapy and stable by imaging (MRI or CT) during the screening period and clinically asymptomatic.
Expansion Group G only: Participants with active (new or progressing) clinically stable brain metastases who do not require immediate CNS-directed treatment as per Investigator's judgement and who are off or receiving low-dose corticosteroids (≤10 mg prednisone or equivalent such as ≤ 1.5 mg/day dexamethasone) in the 7 days prior to first dose of BAY2927088 are eligible.
History of congestive heart failure (CHF) Class >II according to the New York Heart Association (NYHA) Functional Classification or serious cardiac arrhythmias requiring treatment (e.g. ventricular arrhythmias, atrial fibrillation) or any clinically important abnormalities in rhythm, conduction or morphology or resting ECG (e.g., complete left bundle branch block, third degree heart block, second degree heart block, PR interval >250 msec)
Participants with:
Known human immunodeficiency virus (HIV), except as noted below: Participants with history of HIV infection are eligible at the Investigator's discretion provided that: • CD4+ T-cell (CD4+) counts are ≥ 350 cells/uL • The participant has been on established antiretroviral therapy (ART) for at least 4 weeks prior to the start of study drug and has an HIV viral load less than 400 copies/mL prior to start of the study treatment • The ART being used does not contain strong inducers or inhibitors of CYP3A4, and is not anticipated to cause overlapping toxicities with study drug • The participant has not had an opportunistic infection within the past 12 months
Active Hepatitis B infection (positive for Hepatitis B surface antigen [HbsAg]) and Hepatitis B virus [HBV] DNA).
Active Hepatitis C infection (positive anti-HCV Antibody and quantitative HCV RNA results greater than the lower limits of detection of the assay).
NOTE: Participants with history of chronic HBV or HCV infection are eligible at the Investigator's discretion provided that the disease is stable and sufficiently controlled under treatment.
Use of strong CYP3A4 inhibitors and inducers from 14 days prior to first administration of study drug. Strong CYP3A4 inhibitors and inducers are prohibited during the study and until Safety FU (follow up) visit.
