             therapy) is acceptable

             within 28 days prior to step 2 re-registration (if both ALT and AST are done, both
             must be < 2 IULN); for patients with liver metastases, either ALT or AST must be =< 5
             x IULN (if both ALT and AST are done, both must be =< 5 x IULN)

          -  HbA1c < 7% obtained within 28 days prior to step 2 re-registration

             must have undetectable viral load using standard HIV assays in clinical practice; must
             have cluster of differentiation (CD)4 count >= 400/mcL; must not require prophylaxis
             for any opportunistic infections (i.e., fungal, mycobacterium avium complex [mAC], or
             pneumocystis pneumonia [PCP] prophylaxis); must not be newly diagnosed within 12
             months prior to re-registration

          -  Prestudy history and physical exam must be obtained within 28 days prior to
             re-registration

          -  No other prior malignancy is allowed except for the following: adequately treated

             stage I or II cancer from which the patient is currently in complete remission, or any
             other cancer from which the patient has been disease free for five years

          -  Patients must not be pregnant or nursing; women/men of reproductive potential must
             have agreed to use an effective contraceptive method; a woman is considered to be of
             "reproductive potential" if she has had menses at any time in the preceding 12
             consecutive months; in addition to routine contraceptive methods, "effective
             contraception" also includes heterosexual celibacy and surgery intended to prevent
             pregnancy (or with a side-effect of pregnancy prevention) defined as a hysterectomy,
             bilateral oophorectomy or bilateral tubal ligation; however, if at any point a
             previously celibate patient chooses to become heterosexually active during the time
             period for use of contraceptive measures outlined in the protocol, he/she is
             responsible for beginning contraceptive measures

          -  As a part of the Oncology Patient Enrollment Network (OPEN) registration process the
             treating institution's identity is provided in order to ensure that the current
             (within 365 days) date of institutional review board approval for this study has been
             entered in the system

          -  Patients with impaired decision-making capacity are eligible as long as their
             neurological or psychological condition does not preclude their safe participation in
             the study (e.g., tracking pill consumption and reporting adverse events to the
             investigator)

          -  Patients must be informed of the investigational nature of this study and must sign
             and give written informed consent in accordance with institutional and federal
             guidelines
