AIM Biologicals
Targeted Immunomodulating Therapeutics


AIM Biologicals (AutoImmunity Modifying Biologicals) utilize a novel mechanism which is believed to demonstrate that peptide antigens presented on immunosuppressive MHC class I molecules can selectively and efficiently induce antigen-specific tolerance. Based on this mechanism, the targeted immunomodulating therapeutics are being designed as optimized soluble molecules with the goal that they may be adapted to selectively induce tolerance to various autoantigens.

During pregnancy, the maternal immune system tolerates paternal antigens from the embryo but is still effective to protect mother and embryo from foreign antigens. Parts of the natural mechanisms responsible for this feto-maternal immune tolerance form the scientific basis for the concept of AIM Biologicals.

Targeted, highly specific, autoimmunity modifying proteins

Technology derived from body’s natural process that protects a fetus from the mother’s immune system

  • Fetal cells persist in mothers for decades after delivery and vice versa → lasting, selective immune tolerance which cannot be explained by barrier function*

Pre-clinical studies conducted by the Julius-Maximilians-University thus far indicate that tolerance induction appears to be achieved via selective elimination of antigen-specific immune effector cells and via induction of antigen-specific regulatory T cells from naïve T cells.

The Promise of Targeted, Physiological, Antigen-Specific Immunomodulation

Neuromyelitis Optica Spectrum Disorder (NMOSD)

  • Well-defined antigen: Aquaporin-4 (AQP4)

  • NMOSD is an auto-antibody mediated inflammatory CNS orphan disorder with significant unmet medical need affecting 1 per 100,000 people*

Parkinson’s Disease (PD)

  • Neurodegenerative movement disorder affecting over 7 million people worldwide

  • Growing evidence suggests that PD could be considered as an autoimmune disease*

  • α-Synuclein (α-Syn) described as target

Neuromyelitis Optica Spectrum Disorder (NMOSD)



people in the U.S. 
and E

NMOSD, also known as “Devic disease”, is a chronic autoimmune disorder of the brain and spinal cord dominated by inflammation of the optic nerve (optic neuritis) and of the spinal cord (myelitis).
