Brief Summary:

This research study is studying a targeted therapy as a possible treatment for Smoldering Multiple Myeloma.

The following intervention will be involved in this study:

  • Lenalidomide
  • Citarinostat (CC-96241)
  • PVX-410

Condition or disease Intervention/treatment Phase
Smoldering Multiple Myeloma Drug: Hiltonol Drug: Citarinostat Drug: Lenalidomide Biological: PVX-410 Phase 1

Detailed Description:

This research study is a Phase I clinical trial, which tests the safety of an investigational intervention and also tries to define the appropriate dose of the investigational intervention to use for further studies. "Investigational" means that the intervention is being studied.

In this research study, the investigators are studying Smoldering Multiple Myeloma. Smoldering Multiple Myeloma is an early precursor to a rare blood cancer known as Multiple Myeloma, which affects plasma cells. The study will test two different combinations of the study drugs; a combination of the vaccine (PVX-410) along with Citarinostat (CC-96241) and triple combination of the vaccine, Citarinostat, and Lenalidomide.

The vaccine (PVX-410) is a multi-peptide vaccine that contains four synthetic peptides that together are intended to induce a T cell-mediated immune response against the myeloma. The FDA (the U.S. Food and Drug Administration) has not approved PVX-410 as a treatment for any disease.

Citarinostat is an orally active, small-molecule Histone Deacetylase (HDAC) Inhibitor which is being combined here to further augment the immune activity of the vaccine. Citarinostat has not been approved by the FDA as a treatment for any disease.

Lenalidomide is commercially available analogue of thalidomide with immunomodulatory, antiangiogenic, and antineoplastic properties that has demonstrated an increase in immune activity in previous trials. The FDA has approved Lenalidomide as a treatment option for Smoldering Multiple Myeloma. Lenalidomide is being added to the combination of the vaccine and Citarinostat because it is hypothesized that co-administration of lenalidomide along with Citarinostat would further enhance the T cell-mediated immune response induced by PVX-410.
