CM-272, new approach in cancer


Target: DNMT & G9a

Epigenetic modifications are a major driver of biological complexity and can have a role in the development of a variety of disease treatments.

  • Epigenetics is an emerging area covering a broad range of mode of actions. However, only four drugs are currently approved and eleven agents are in early-stage trials.
  • Novel proprietary compounds binding two epigenetic targets have been developed:
    • More effective than reference epigenetic compounds vs different cancer cell lines.
    • First-in-class dual reversible inhibitors of DNMT and HMT.

Opportunity and Competitive Landscape

  • The fact that the epigenome is dynamic is of particular relevance to drug development, as it implies that specific disease-associated epigenetic states may be reversible with treatment.
  • To date, the most investigated therapeutic area in terms of epigenetics is cancer.
  • Beyond cancer, epigenetic factors have been implicated in inflammatory, autoimmune, metabolic, neurological and cardiovascular disorders.
  • Four drugs with epigenetic mechanisms of action are currently approved. All of them are anticancer drugs and they are only focused on 2 modes of action (HDACs and DNMT-irreversible).
  • Mostly, research is focused on developing novel HDAC inhibitors.

Application Scope

Cancer: a wide range of neoplastic diseases in where the epigenetics targets addressed are implied: from hematological malignancies, such as Acute leukemias and lymphomas, to solid tumors in liver, bladder and others.

New Agents

  • Small molecules hitting DNMT and HMT, IC50 at low nM range.
  • They are not SAM-competitive; in fact, selective vs 90 additional epigenetic targets MoA validated, through epigenetic marks, in cell lines and in-vivo.
  • First-in-class reversible inhibitors.

Proof of Concept

In vitro studies: G9a and DNMT1 inhibitory potencies (expressed as pIC50) and the growth inhibitory potencies (expressed as pGI50) for compounds CM-272, CM-579, selective G9a inhibitors (BIX-01294 and UNC-0638) and irreversible DNMT inhibitors (Azacitidine and Decitabine).

In vivo studies: PoC and efficacy studies using CM-272 in Acute Myeloyd leukemia (A), Acute Lymphoblastic leukemia, Lymphoma, Hepatocarcinoma and Bladder Cancer.

Estudios invivo. CM-272

Combination with Immunotherapy (CM-272+anti-PD-L1 reduce the Bladder cancer and metastases incidence by an endogenous antitumor immune response and immunogenic cell death (A) with the conversion of a cold immune-tumor into a hot tumor) and with Anti-Apoptotic drugs (CM-272 sensitizes cells of hematological neoplasia to BCL-2, BCL-XL or MCL-1 inhibitors and mitochondrial apoptosis).
