An ImmunoGen ADC contains a manufactured antibody that binds to a target found on cancer cells, with one of the company's potent cell-killing agents attached as a "payload". The antibody serves to deliver the cell-killing agent specifically to cancer cells bearing its target and the payload serves to kill these cells. In some cases, the antibody also has anticancer activity.

Linkage technology

Currently approved ADCs with ImmunoGen technology employ one of the company's maytansinoid cell-killing agents, either DM1 or DM4, or one of the company's DNA-acting IGN payloads.

  • DM1 attached to an antibody with ImmunoGen's thioether linker is called "emtansine" in its INN name
  • DM1 attached to an antibody with ImmunoGen's SPP linker is called "mertansine".
  • DM4 attached with ImmunoGen's SPDB linker is called "ravtansine"
  • DM4 attached with ImmunoGen's sSPDB linker is called "soravtansine"
    • mirvetuximab soravtansine

ImmunoGen also developed isatuximab, a monoclonal antibody without linkage to a toxin.

Pipeline

ImmunoGen uses its ADC technology to develop its own product candidates. The mirvetuximab, which has been submitted for FDA approval, is being developed as a monotherapy or a standalone treatment for ovarian cancer.[5][6] Other products currently in clinical-stage development include:[7]

Collaborations & licensing

The company also selectively outlicenses limited use of its technology to other companies. Companies licensing ImmunoGen's technology include Amgen, Bayer HealthCare, Biotest, Genentech/Roche, Eli Lilly, Novartis, Sanofi, and Takeda.[7] Roche's Kadcyla (ado-trastuzumab emtansine) utilizes ImmunoGen's ADC technology. It has been approved and launched in a number of countries, including the US, where it is marketed by Genentech, a member of the Roche Group.[11][12] In October 2015, the company disclosed that Kadcyla had failed to meet its primary endpoint in the Phase II/III GATSBY trial investigating the second line treatment of HER2-positive advanced gastric cancer.[13]
