Cancer cells differ from normal cellsfrom normal cellseg., in gene expression
This can be sensed by T cells - no matter which cellular compartment is affected by the changea ected by t e c a ge

3 classes of tumor antigens

Limited to few cancer entities
We know plenty of such antigens; immune responses tend to be weak but stronger immune responses may lead
This is our vision
but stronger immune responses may lead to autoimmunity

Follow-up for OS17 vaccinations over 9 months
IMA901 plus GM-CSF (i.d.)
Stratification:1) First-line therapy: cytokine(s) vs TKI
2) Risk score: low vs intermediate [MSKCC]
Patients: mRCC patients following failure of first-line treatment (TKI and/or cytokines)
Treatment: Single infusion of cyclophosphamide as immunomodulator (300 mg/m2) prior to the 1st vaccination with IMA901 (413 g i d ) and GM CSF (75 g i d ) to the 1st vaccination with IMA901 (413 g i.d.) and GM-CSF (75g i.d.)
Endpoints: Primary EP was DCR after 6 months. Secondary EP included PFS, OS, and safety. Immunomonitoring for peptide-specific T-cells (ELISpot and MHC multimer) and Tregs
Conduct: 68 patients were randomized between 2007 and 2009 in 23 centers across 10 European countries

Conclusions
Multipeptide immunotherapy in prostate carcinoma patients
- is well tolerated- induces T cell responses in most patients- shows clinical benefit in a fraction of patients- gives best results with TLR7 ligands as adjuvants
some peptides are not immunogenic- some peptides are not immunogenic

Limited to few cancer entities
We know plenty of such antigens; immune responses tend to be weak but stronger immune responses may lead
This is our vision
but stronger immune responses may lead to autoimmunity

ABSTRACT
Tumors carry multiple somatic mutations, the majority of which are unique to
individual patients Recent data imply that immunogenic tumor mutations can beindividual patients. Recent data imply that immunogenic tumor mutations can be
exploited for the treatment of cancer patients. Here we propose a development
strategy for actively personalized vaccines (APVACs) targeting multiple tumor
mutations. This strategy is based on the existing regulatory framework thus
facilitating the way towards first clinical testing.
