Summary of preclinical, translational, and clinical evidence of the DRibbles vaccine

In the Lab	Bench to Bedside	In the Clinic
• DRibbles vaccine comprises autophagosome-packaged cellular proteins, short-lived proteins and ribosomal proteins that may be missed by endogenous immunity	• The DPV-001 DRibbles contains over 2,000 proteins, of which 25 are known tumor-associated antigens	• Dribbles vaccine + docetaxel was well tolerated in a phase I NSCLC trial
• DRibbles delays growth in both “autologous” and “allogeneic” pre-preclinical models	• The DPV-001 cell lines contain thousands of mutations and polymorphisms that could function as altered-peptide ligands	• A Phase II trial comparing DRibbles + either GM-CSF or Imiquimod in stage IIIA/B NSCLC is ongoing
• DRibbles contains innate immunity mediators (DAMPs) and surface ligands for CLEC9a, which facilitate uptake by APCs for cross-presentation	• Each lung adenocarcinoma sequence from the TCGA database shares at least one mutation with the polymorphisms found in DPV-001	• A Phase I trial of DRibbles + imiquimod + low-dose cyclophosphamide is ongoing
	• DPV-001 contains common oncogene mutants such as KRAS G12C	• DRibbles induced increased antibody reactivity in the first 2 patients treated on a phase II trial
