Primary purpose: TREATMENT

Brief summary: This is the first study where BAY1125976 is given to humans. Patients (all comers) will receive the study drug treatment in a dose-escalation scheme (no placebo group) to determine the safety, tolerability and maximum tolerated dose (MTD) of BAY1125976. The relative bioavailability of liquid service formulation and tablets will be determined.

After the MTD is defined breast cancer patients with and without AKT1 mutation will be treated.

The study will also assess the pharmacokinetics, biomarker status, pharmacodynamic parameters and tumor response of BAY1125976.

BAY1125976 will be given daily as single oral application. Treatment will be stopped if the tumor continues to grow, if side effects, which the patient cannot tolerate, occur or if the patient decides to exit treatment.


Eligibility criteria: Inclusion Criteria:

* For dose escalation cohorts: Subjects with advanced, histologically or cytologically confirmed solid tumors are eligible. Subjects' tumors (all comers) must be refractory to standard treatment with no standard therapy available, or subjects actively refuse any treatment, which would be regarded standard. In addition, the investigator must judge the experimental treatment as clinically and ethically acceptable
* For expansion cohort only: Subjects with histologically or cytologically proven metastatic breast cancer (with and without AKT1 E17K (G49A) mutation) or subjects with known AKT1 E17K (G49A) mutation in any other advanced solid tumor with at least one line of chemotherapy in the metastatic setting and not amenable to surgery with curative intent
* Subjects must have measurable disease (Response evaluation criteria in solid tumors (RECIST 1.1)
* Eastern Cooperative Oncology Group (ECOG) Performance Status 0 - 2
* Bone marrow, liver and renal functions as assessed by adequate laboratory methods to be conducted within 7 days prior to starting study treatment
* Subjects must provide tumor biopsies before treatment
* Recovery to CTCAE (Common Terminology Criteria for Adverse Events Version 4.03) Grade 0 or Grade 1 or recovery to baseline preceding the prior treatment of any previous drug / procedure-related toxicity (except alopecia, anemia, and hypothyroidism)

Exclusion Criteria:

* History of cardiac disease including congestive heart failure \> New York Heart Association (NYHA) Class II
* Subjects with type 1 or type 2 diabetes mellitus
* Subjects with fasting glucose \>125 mg/dL in 2 independent measurements or glycated hemoglobin (HbA1c) ≥ 7%
* Moderate and severe hepatic impairment, i.e. Child-Pugh B or C
* Active infections of CTCAE (Common Terminology Criteria for Adverse Events Version 4.03) Grade \>2 or infections of CTCAE Grade 2 not responding to therapy
* Symptomatic metastatic brain or meningeal tumors unless the patient is \> 3 months from definitive therapy, has a negative imaging study within 4 weeks of study entry and is clinically stable with respect to the tumor at the time of study entry.
* Subjects undergoing renal dialysis
* Previous or concurrent cancer that is distinct in primary site or histology from the cancer being evaluated in this study except cervical carcinoma in situ, treated basal cell carcinoma, superficial bladder tumors (Ta, Tis \& T1) or any cancer curatively treated \> 3 years prior to study entry
* Autologous bone marrow transplant or stem cell rescue within 4 months of study entry
* Treatment with oral steroids (dose ≥ 10 mg/day of methylprednisolone or equivalent)
* Clinically relevant findings in the ECG such as a second- or third-degree AV block, prolongation of the QRS complex over 120 msec or of the QTcF-interval over 450 msec
* Acute toxic effects of previous anticancer chemotherapy or immunotherapy have to be normalized to CTCAE Grade equal or lower than 1 (excluding alopecia)
