Intervention: 5.0g SRT501; Bortezomib
Intervention description: 5.0g SRT501 will be supplied in clinical kits as a powder which will be reconstituted with vehicle and water into a liquid suspension. SRT501 will be administered orally as a liquid suspension for 20 consecutive days in each 21 day cycle.; Bortezomib (1.3 mg/m2) will be given as an intravenous solution in a 3-5 second push on Day 1, 4, 8 and 11 in every 21 day cycle.
Intervention MeSH terms: Bortezomib
Phase: Phase 2
Study type: Interventional
Primary purpose: Treatment
Intervention model: Single Group Assignment
Masking: None (Open Label)
Enrollment: 24.0
Sex: All
Minimum age: 18 Years
Healthy volunteers: No

Summary:

      The primary purpose of this study is to determine the safety and tolerability of SRT501 (5.0
      g) with or without concurrent bortezomib administration, when administered once daily in 21
      day cycles, in male and female subjects with Multiple Myeloma.

      The purpose is also to define objective response (ORR, CR, PR, MR, SD) and time to
      progression (TTP) of SRT501 with or without concurrent bortezomib administered concurrently
      in male and female subjects with Multiple Myeloma.

      In addition, 15 subjects will participate in a sub-study to assess the pharmacokinetics of
      SRT501.
    

Eligibility criteria:

        Inclusion Criteria:

             clinically insignificant.

          -  Subject has the ability to communicate with the investigative site staff in a manner
             sufficient to carry out all protocol procedures as described.

          -  Subject must be able to adhere to the study visit schedule and other protocol
             requirements.

          -  Subject must understand and voluntarily sign an informed consent document.

          -  All subjects of reproductive potential must agree prior to study entry to use adequate
             contraception (hormonal or double barrier method of birth control; abstinence) for the
             duration of the study dosing and at least 12 weeks after completion of study drug.

          -  Adequate end organ function, defined as the following:

               -  Total bilirubin < 2 x ULN, unless attributable to Gilbert's disease

               -  ALT (SGPT) and AST (SGOT) < 2.5 x ULN

               -  Creatinine < 2.0 x ULN

               -  ANC > 0.5 x 10^9/L

               -  Platelets > 20,000 cells/mm3

        Exclusion Criteria:

          -  Intolerance to resveratrol, SRT501 or bortezomib or significant allergy to either
             compound, boron or mannitol or significant prior toxicity with either agent that would
             preclude the safe use of that agent. Prior therapy with either compound is permitted.

             cell carcinoma of the skin.

          -  An uncontrolled intercurrent illness including, but not limited to, recent (≤ 6
             months), ongoing or active infection, symptomatic congestive heart failure, unstable
             angina pectoris, cardiac arrhythmia, acute diffuse infiltrative pulmonary or

          -  Subjects with a hemoglobin < 8.0 g/dL. Transfusions and/or EPO treatment are permitted
             in subjects who are potentially excluded by this criteria.

          -  Any condition, including laboratory abnormalities, that in the opinion of the
