Primary Objective:

- To assess the safety, tolerability and plasma pharmacokinetics (PK) of SAR245408 given once daily as a tablet formulation of polymorph E in subjects with solid tumors or lymphoma.

Screening: 1 to 28 days Study treatment period: two 28-day cycles (56 days) End-of-treatment visit: no later than 7 days after the last study drug administration Subjects not eligible for treatment continuation after Cycle 2 will be followed up for safety; a follow-up visit will be performed within 30 ± 3 days after the last study drug administration Subjects eligible for treatment continuation after Cycle 2 will be offered the opportunity to enroll in the treatment-extension study TED12414.

Total duration of study participation for each patient: 58 to 118 days.

Inclusion criteria :

• Solid tumor that is metastatic or unresectable, or relapsed or refractory lymphoma (including chronic lymphocytic leukemia/small lymphocytic lymphoma), for which standard therapies are no longer effective or there are no therapies known to prolong survival or patient cannot tolerate or has contra-indication for a standard therapy and there is no alternative therapies.
• Male or female patient > or = 18 years old.
• Weight > or = 40 kg.
• Eastern Cooperative Oncology Group performance status < or = 1.
• Adequate white blood cells, platelets, and haemoglobin.

• Prior treatment with a small-molecule kinase inhibitor (including investigational agents) within 2 weeks, or 5 half lives of the drug or active metabolites, whichever is longer, before the first dose of study drug.
• Any other investigational therapy within 4 weeks before the first dose of study drug.
• Intolerance to prior treatment with a PI3K inhibitor.
• Prior anticancer hormonal therapy within 2 weeks before the first dose of study drug.
• Prior radiation therapy within 2 weeks before the first dose of study drug.
• Uncontrolled brain metastases or primary brain tumor.
• Hereditary or acquired immunodeficiency syndrome or human immunodeficiency virus (HIV) infection.
• Positive serologies for Hepatitis B surface antigen (HBsAg) or anti-Hepatitis C virus (anti-HCV) antibodies.
• Patient is pregnant or breastfeeding.
• History of gastrointestinal surgery, or presence of gastrointestinal abnormality or disease, that may affect the pharmacokinetics of study drug.
