Enables High Affinity Monoclonal

Antibody Discovery

Isolated antibodies possess much greater drug binding and selectivity compared to previous efforts in the scientific literature

Pharmacokinetics of free drug

Substance of abuse distributes from blood to the brain, where it interacts with receptors to cause psychotropic and potentially dangerous effects.

Plasma
CNS

Pharmacokinetics of drug-specific antibody​

Our antibody therapy binds to the substance of abuse in the bloodstream, preventing it from getting into the brain and exerting its harmful and psychotropic effects.

Plasma

Monoclonal antibodies sequester the substance of abuse in the bloodstream, preventing it from affecting the brain. The use of monoclonal antibodies allows for tight control of dosing as well as providing immediate protection after treatment. The monoclonal antibody is restricted to the blood stream, and thus not likely to have abuse potential of its own or to induce psychiatric side-effects common to other treatments for substance use disorders.
