Inclusion Criteria:

• Patients with confirmed metastatic RCC
• Patients must have documented progression on treatment with sunitinib or sorafenib. Prior therapy with bevacizumab and/or cytokines (i.e., IL-2, interferon) is permitted. Prior vaccine therapy in the adjuvant setting is also permitted. Patients can have failed therapy with ONE prior mTOR inhibitor.
• Patients must have at least one measurable lesion on computer tomography (CT) Scan or magnetic resonance imaging (MRI) using Modified RECIST criteria.

• Patients must have normal organ and marrow function, unless in the opinion of the treating investigator, the abnormality is related to tumor, and the study chairman agree the abnormality is unlikely to affect the safety of perifosine use. Normal organ and marrow function is described below:

  • ANC >= 1.5 x 109/L
  • Platelets >= 75,000/ mm3
  • HCT >= 28% (with or without growth factor support)
  • Creatinine <= 3.0 mg/dl
  • Total bilirubin <= 1.5 x upper limit of normal
  • Transaminase <= 2.5 x upper limit of normal
• ECOG performance status of 0 or 1
• Patients with CNS metastases must be clinically stable for at least 2 months following treatment with radiation therapy, surgery, or both; and be off corticosteroids and anti-seizure medication.
• Patients with a life expectancy ≥6 months
• Age ≥18 years old

• Patients currently receiving sorafenib or sunitinib who have received either of these within 2 weeks prior to study entry.
• Patients may have had prior sorafenib OR sunitinib BUT cannot have been treated with both VEGF receptor inhibitors.
• Patients with a known hypersensitivity to perifosine or its excipients.
• Female patients who are pregnant or breast feeding, or adults of reproductive potential who are not using effective birth control methods.
• Patients who are using other investigational agents or who had received investigational drugs <= 4 weeks prior to study entry.
• Patients unwilling to or unable to comply with the protocol.
