• Male participants, even if surgically sterilized (i.e., status post vasectomy), who agree to practice effective barrier contraception during the entire study treatment period and through 3 months after the last dose of study drug, or agree to practice true abstinence, when this is in line with the preferred and usual lifestyle of the participant. (Periodic abstinence [e.g., calendar, ovulation, symptothermal, post ovulation methods for the female partner] and withdrawal are not acceptable methods of contraception.)
• Voluntary written consent must be given before performance of any study-related procedure not part of standard medical care, with the understanding that consent may be withdrawn by the participant at any time without prejudice to future medical care.

• Manifestations of malabsorption due to prior gastrointestinal (GI) surgery, GI disease, or for an unknown or other reason that may alter the absorption of Sapanisertib.

• Significant active cardiovascular or pulmonary disease at study entry
• History of arrhythmia requiring an implantable cardiac defibrillator
