Kinoid Technology: Vaccine-Like Approach to Treating Chronic Diseases

– Target multiple epitopes

– Blocking of overproduced cytokine, and its pro inflammatory effects

– Specific to cytokine: no cross-neutralization with other cytokines

– No blocking anti-antibodies (ADA)

– Broad and sustained efficacy

– T cell tolerance is NOT broken: no uncontrolled autoimmunity

The Kinoid is an immunogenic compound made of: T Cells generated by the carrier protein (KLH) bypass B cell tolerance to induce self polyclonal anti-cytokine antibodies:

Conjugation and

inactivation

Polyclonal antibodies to targeted cytokine

Components of active immunotherapy Immunization Stimulation of the body’s immune system

Polyclonal antibodies

Kinoid Technology: Superiority of the Polyclonal Approach

INDUCING A SAFE AND EFFECTIVE POLYCLONAL RESPONSE FROM THE BODY’S OWN IMMUNE SYSTEM

Monoclonal antibodies:

– Injection of non-self Abs

– Abs bind to one specific epitope of the cytokine

– Risk of monoclonal antibody rejection and loss of efficacy (Anti-drug antibodies)

Current treatments

Monoclonal antibodies

Polyclonal antibodies:

– Self Abs generated by the patient’s immune system

– Abs bind to multiple epitopes of the targeted cytokine

– Better and sustained antibody efficacy

– Excellent tolerance

Kinoid Technology: Competitive Positioning vs. Monoclonal Antibodies

KINOIDS: A MAJOR BREAKTHROUGH WITH THE POTENTIAL TO SUPERSEDE MONOCLONAL ANTIBODIES

Fully human response: no risk of rejection

3 to 5 injections per year vs. once every 2 – 4 weeks

IN CONCLUSION: • Very strong antibody response (40x>TNF-Kinoid)

• Strong response neutralizing antibodies

• Those antibodies neutralize all 13 subtypes of IFNα, in contrast with monoclonal anti-IFNα antibodies (2 subtypes only are completely neutralized) • Higher production of binding and neutralizing antibodies in patients with more severe lupus • Improvement of disease biomarkers is correlated with the intensity and duration of the neutralizing response

Lessons Learned from TNF-Kinoid Studies for IFNα-Kinoid Program

- IFNα animal model relevant - Much higher anti-IFNα antibody response: 20x higher than TNF-K - Neutralizing antibodies, dose dependent, in human - Neutralization of 13 subtypes of IFNα vs 2-7 with Mabs - Neutralization of IFN gene signature - Correlation between antibody levels and neutralization of IFN gene signature

TNF-KINOID STUDY RESULTS DO NOT PREDICT OUTCOME FOR IFNα-KINOID STUDY

Learning curve on active immunotherapy

- Good safety and tolerability of the product (5 clinical trials to date) - Highest antibody response obtained at highest dose + boost (TNF-K-003, 005 and IFN-K-001) - Possible interference of Kinoid with residual antibodies (TNF-K-005) - Neutralizing antibodies necessary to obtain clinical response ; simple presence of binding

antibodies not sufficient (TNF-K-006)

Programs of Preclinical Development

VEGF-Kinoid in Age-related Macular Degeneration (AMD)

– Very encouraging results had been obtained with a preliminary VEGF Kinoid

– Prevention of laser induced neo vascularization in mice

– Results presented at EVER conference in 20093

VEGF-Kinoid in solid tumors

– Very encouraging results had been obtained with a preliminary VEGF Kinoid

IL-4 / IL-13 -Kinoid in allergies

– Preliminary studies indicate the potential to control allergic reactions thanks to a Kinoid targeting IL-44.

Proc Natl Acad Sci U S A. 2007 Feb 20;104(8):2837-42. Epub 2007 Feb 14. VEGF kinoid vaccine, a therapeutic approach against tumor angiogenesis and metastases. Rad FH, Le Buanec H, Paturance S, Larcier P, Genne P, Ryffel B, Bensussan A, Bizzini B, Gallo RC, Zagury D, Uzan G.

Abstract Tumor growth depends on blood supply, requiring the development of new vessels, and vascular endothelial growth factor (VEGF) plays a central role in neoangiogenic processes. For this reason, VEGF represents a target for the development of new therapeutic antiangiogenic molecules. Clinical trials using anti-VEGF mAbs such as bevacizumab have validated the efficacy of this therapeutic approach but have also revealed adverse effects. Here we report that a VEGF-derived immunogen, consisting of a heterocomplex of a murine (m)VEGF and keyhole limpet hemocyanin, called "mVEGF kinoid," triggered a strong Ab immune response in mice. The anti-VEGF Abs inhibited both the proliferation of human umbilical vein endothelial cells cultured in the presence of mVEGF and the binding of mVEGF to its receptor-2 Flk-1. In mVEGF kinoid-immunized BALB/c mice challenged with syngeneic CT26 colorectal tumor cells, the number and size of lung metastases were significantly decreased. In human (h)VEGF kinoid-immunized BALB/c mice, high levels of serum Abs to hVEGF were present, and purified IgG from these mice decreased by > or =50% the tumor growth of human A673 rhabdomyosarcoma cells and HT29 colon carcinoma xenografted in Swiss nude and NOD/SCID mice, respectively. Tumor cell growth inhibition was similar to that observed in mice receiving therapeutic doses of bevacizumab. These experiments suggest that a therapeutic vaccine containing VEGF kinoid may represent a strategy for safely combating VEGF-dependent neovascularization and metastases occurring in malignant tumors.
