Key Inclusion Criteria:

Patients eligible for inclusion in this study had to meet all of the following criteria:

1. Patient's age was ≥ 18 years of age at the time of signing informed consent.

Patient had a confirmed diagnosis of a selected solid tumor (except for primary diagnosis of urothelial tumors, hepatocellular carcinoma (HCC), endometrial carcinoma, metastatic breast cancer (mBC), squamous NSCLC, and renal cell carcinoma (RCC)) or hematologic malignancies (except for primary diagnosis of FLT3 AML and multiple myeloma). Additional tumor types could be excluded during the course of the study in the case of early futility or success based upon an interim analysis or at the discretion of Novartis.

3. Patient was in need of treatment because of progression or relapse defined as:

• radiological progression for solid tumor and lymphoma

• for hematologic malignancies, measureable progression or relapse by appropriate criteria

24. Cirrhosis of the liver or known hepatitis B or C infection that was either acute or was considered chronic because the virus did not become undetectable:

1. Hepatitis C Virus (HCV) infection: acute or chronic infection as depicted by a positive HCV RNA testing (note: in a patient with known anti-HCV but with a negative test for HCV RNA, re-testing for HCV RNA 4-6 months later was requested to confirm the resolution of HCV infection).

2. Hepatitis B Virus (HBV) infection: acute infection (HBsAg+ with or without HBeAg+ or detectable serum HBV DNA), HBV carriers as evidence by ongoing presence of HBsAg and detectable serum HBV DNA levels.

25. Known diagnosis of human immunodeficiency virus (HIV) infection (HIV testing was not mandatory).

26. Patients who received investigational agents within ≤ 5t1/2 of the agent (or ≤ 4 weeks when half-life was unknown) prior to starting study drug.

27. Patient with history of non-compliance to medical regimen.

28. Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive hCG laboratory test.

29. Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they were using highly effective methods of contraception (defined below). Highly effective contraception had to be used by both sexes (female patients and their male partners) during study treatment and for 30 days after the last doseof study medication.

Highly effective contraception methods included:

• Total abstinence (when this was in line with the preferred and usual lifestyle of the subject). Periodic abstinence (e.g., calendar, ovulation, symptothermal, post- ovulation methods) and withdrawal were not acceptable methods of contraception

• Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy) or tubal ligation at least six weeks before taking study treatment.

In case of oophorectomy alone, only when the reproductive status of the woman was confirmed by follow up hormone level assessment

• Male sterilization (at least 6 months prior to screening). For female patients on the study the vasectomized male partner was the sole partner for that subject.

• Combination of the following (a+b):

1. Placement of an intrauterine device (IUD) or intrauterine system (IUS)

2. Barrier methods of contraception: Condom or Occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/vaginal suppository

30. Oral, implantable, or injectable hormone contraceptives might be affected by cytochrome P450 interactions, and were therefore not considered effective for this study Women of child-bearing potential (sexually mature women) who had not undergone a hysterectomy or who were not naturally postmenopausal for at least 12 consecutive months (i.e., who has had menses any time in the preceding 12 consecutive months), were required to have a negative serum pregnancy test ≤ 14 days prior to starting study drug.

31. Post-menopausal women were allowed to participate in this study. Women were considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or six months of spontaneous amenorrhea with serum FSH levels > 40 mIU/mL or have had surgical bilateral oophorectomy (with or without hysterectomy) at least six weeks prior to entry in the study. In the case of oophorectomy alone, only when the reproductive status of the woman was confirmed by follow up hormone level assessment, then she was considered not of child bearing potential.

32. Fertile males not willing to use contraception. Fertile males must use condom with spermicide. Highly effective contraception, as defined above, was to be used by both sexes (male patients and their female partners) during study treatment and for 90 days after the last dose of study medication and was not to father a child in this period. A condom was required to be used also by vasectomized men in order to prevent delivery of the drug via seminal fluid.
