Purpose
During the course of HIV infection the number of CD4 cells decreases, resulting in a reduced immunological response and ultimately immune deficiency. Vacc-4x is a peptide-based HIV immunotherapy and the primary objective is to strengthen the immune system's response to HIV p24. By adding Lenalidomide, an immunomodulatory agent, as a supporting drug, it is anticipated that the effect of Vacc-4x might be enhanced.

Detailed Description:
Human immunodeficiency virus (HIV) infects the CD4 subset of T-cells that are critical for initiating immune responses to infection. The level of CD4 cells in the blood is a marker of a patient's immunological status. The number of CD4 cells decreases in the course of the HIV infection and results in a reduced immunological response and eventually immune deficiency.
Vacc-4x is one of the few peptide-based therapeutic vaccines tested, and consists of four, slightly modified HIV Gag p24 consensus peptides. Vacc-4x was first tested by intradermal injections using GM-CSF as adjuvant. A recent multinational placebo-controlled study found improvement of vaccine-specific T cell immunity and decrease in viral loads (presented at the AIDS vaccine 2011 conference, Bangkok).
Lenalidomide (CC-5013) is a substance in the class of immunomodulatory agents. The lenalidomide mechanism of action includes anti-neoplastic, pro-erythropoietic, and immunomodulatory properties. Lenalidomide inhibits proliferation of certain hematopoietic tumor cells, enhances T cell- and Natural Killer (NK) cell-mediated immunity and increases the number of NK T cells.
The anti-HIV p24 immune response resulting from Vacc-4x immunization could in combination with ART potentially improve immune reconstitution in patients who have not fully regained a healthy CD4 level (> 600 x106/L). Adding the immunomodulatory agent Lenalidomide (CC-5013) to Vacc-4x immunization could enhance the immune response to Vacc-4x and further strengthen immune reconstitution.

Unacceptable values of the hematologic and clinical chemistry parameters (including those associated with hemophilia), as judged by the Investigator or the Sponsor (or designee), including creatinine values >1.5x upper limit of normal (ULN), and AST (SGOT), ALT (SGPT), and alkaline phosphatase values >2.5x ULN.

- 11. The development of erythema nodosum if characterized by a desquamating rash while previously
- 12. Incapability of compliance to the treatment protocol, in the opinion of the Investigator.
