Anti-Methamphetamine Products

antibodies in bloodstream

InterveXion’s anti-METH therapies work by preventing the abused drug from rapidly reaching the brain in large quantities. These therapies involve antibodies that can “absorb” METH in the bloodstream to block their rewarding effects and simultaneously reduces their detrimental health effects. In addition to reducing the acute effects of overdose, these antibodies may also be used in the chronic setting to help abusers overcome their dependency.

Anti-METH monoclonal antibody

Chimeric anti-METH monoclonal antibody mAb7F9 (ch-mAb7F9) is the most developed product in our pipeline. We have a Master Cell Bank of a CHO cell line that produces about 2 g/L of culture medium. A 200L GMP batch was manufactured to produce the antibody for our Phase 1 human studies. InterveXion submitted the IND for this product in March 2012 and the Phase 1a safety study began in May 2012. More details on the clinical trial may be found on clinicaltrials.gov.

The next steps in the ch-mAb7F9 development program include further nonclinical toxicology testing then a Phase 1b clinical study in METH-using volunteers. This study will provide further safety information and early efficacy data to support the use of ch-mAb7F9 in long-term METH treatment programs.

Anti-METH Vaccine

Additionally, an anti-METH active vaccine product is in early stages of development. The lead candidate and adjuvant have been selected and the final immunization schedule and dose details are being decided. InterveXion is currently pursuing funding for GMP manufacturing and IND-enabling toxicology testing.
