Combination Trial of Pimasertib (MSC1936369B) With Temsirolimus

The research trial is testing the experimental drug pimasertib and the drug Torisel, given together, in the treatment of advanced solid tumors. The primary purpose of the study is to determine the maximum tolerated dose (MTD) and the recommended Phase 2 dose (RP2D) of the drug combination.

* Age \>= 18 years.
* Subject has read and understands the informed consent form and is willing and able to give informed consent.
* Performance Status score of less than or equal to (\<=) 1 according to the Eastern Cooperative Oncology Group (ECOG) scale.
* Women of childbearing potential must have a negative blood pregnancy test at the screening visit.
* Female subjects of childbearing potential and male subjects with female partners of childbearing potential must be willing to avoid pregnancy by using an adequate method of contraception for 2 weeks prior to screening, during the trial and for 3 months after the last dose of trial medication.

Additional inclusion criteria also apply.

* Baseline corrected QT interval on screening electrocardiogram (ECG) (QTc) \>= 460 ms or left ventricular ejection fraction (LVEF) \< 40% on screening echocardiogram.
* Other uncontrolled intercurrent diseases
* Retinal degenerative disease (hereditary retinal degeneration or age-related macular degeneration), history of uveitis or history of retinal vein occlusion, or medically relevant abnormal ophthalmology assessments at screening.
