  • MM-121 (Signaling Inhibitor)

    • Indication:
    • Description:
    • Target
    • NSCLC, Breast Cancer, Ovarian Cancer
    • Monoclonal Antibody
    • ErbB3

    MM-121/SAR256212 is a fully human monocolonal antibody that targets the HER3 receptor. Merrimack’s Network Biology approach identified HER3 as a critical tumorigenic node in several types of cancer.

  • MM-111 (Signaling Inhibitor)

    • Indication:
    • Description:
    • Target
    • Gastric cancer (2nd line, 2 indications)
    • Bi-specific antibody
    • ErbB3 & ErbB2

    MM-111 is a first-in-class bispecific antibody that has been shown in preclinical studies to bind with both specificity and avidity to HER2 and HER3 expressing tumor cells. The HER2 arm is responsible for initial tumor cell targeting and docking, while the therapeutic HER3 arm is designed to block heregulin-induced cell signaling.

  • MM-151 (Signaling Inhibitor)

    • Indication:
    • Description:
    • Target
    • Refractory advanced solid tumors
    • Oligoclonal Antibody
    • EGFR

    MM-151 is an oligoclonal therapeutic consisting of a mixture of three fully human monocolonal antibodies designed to bind and inhibit signaling of the Epidermal Growth Factor Receptor (EGFR).

  • MM-141 (Signaling Inhibitor)

    • Indication:
    • Description:
    • Target
    • Cancer
    • Bispecific tetravalent antibody
    • IGF-1R & ErbB3

    MM-141 is a monoclonal antibody that acts as a tetravalent inhibitor of PI3K/AKT/mTOR, which is a major pro-survival pathway tumor cells use as a resistance mechanism to anti-cancer therapies.

  • MM-131 (Signaling Inhibitor)

    • Indication:
    • Description:
    • Target
    • Cancer
    • Multispecific Antibody
    • Undisclosed

    MM-131 is currently in preclinical development.

  • MM-398 (Nanotherapeutic)

    • Indication:
    • Description:
    • Target
    • Pancreatic Cancer (2nd line, 2 indications), Colorectal Cancer, Glioma
    • Nanotherapeutic
    • Encapsulated irinotecan

    MM-398 is a nanotherapeutic consisting of the chemotherapuetic irinotecan, encapsulated in a liposomal sphere. MM-398 is designed to rely on the natural blood flow of the tumor to direct the therapy directly to the site of the cancer and minimize exposure to non-target cells.

  • MM-302 (Nanotherapeutic)

    • Indication:
    • Description:
    • Target
    • Advanced HER2+ breast cancer
    • Antibody targeted nanotherapeutic
    • HER2-targeted encapsulated doxorubicin

    MM-302 is a HER2-targeted nanotherapeutic consisting of the chemotherapeutic doxorubicin, encapsulated in a liposomal sphere. Doxorubicin has been a standard therapy for the treatment of breast cancer for more than 30 years.
