chemotherapy or investigational agent with limited potential for delayed
toxicity is permitted if terminated at least 5 halflives prior to Day 1 of trial

- Extensive prior radiotherapy on more than 30% of bone marrow reserves, or prior
bone marrow/stem cell transplantation.

3. The subject has not recovered from toxicity due to prior therapy to baseline or
Common Terminology Criteria for Adverse Events (CTCAE v4.0) of Grade 1 or less
(except alopecia).

4. The subject has poor organ or marrow function

5. History of CNS metastases or primary CNS tumor, unless subject has been previously
treated for these conditions, is asymptomatic and has had no requirement for
anticonvulsants or high dose corticosteroids for a minimum of 2 weeks prior to entry
into the trial.

6. History of abdominal fistula, gastrointestinal perforation, or intra-abdominal

symptomatic cardiac conduction abnormality, pacemaker, or other clinically
significant cardiac disease or history of a stroke within 3 months prior to entering
the trial.

9. Baseline corrected QT interval on screening electrocardiogram (ECG) (QTc) ≥ 460 ms or
left ventricular ejection fraction (LVEF) < 40% on screening echocardiogram.

10. Other uncontrolled intercurrent diseases

11. 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.

12. Known or suspected allergy to MSC1936369B, temsirolimus, other rapamycins (sirolimus,
everolimus, etc.), their excipients, or any agent given in the course of this trial.

13. Immunization with attenuated live vaccines within one week of trial entry (examples
of live vaccines include intranasal influenza, measles, mumps, rubella, oral polio,
BCG, etc.).

14. Concomitant use of any medications or substances that are strong inhibitors or
