Preclinical evaluation of the antitumor activity of a new CXCR4 inhibitor: a novel therapeutic approach in diffuse large B-cell lymphoma

| Sumario: | [eng] Constitutive activation of the chemokine receptor CXCR4 is associated with tumor progression, invasion and resistance to treatment. Overexpression of CXCR4 in diffuse large B-cell lymphoma (DLBCL) confers a reduced prognosis. However, the biological relevance of this receptor in DLBCL progression remains underexplored. In this thesis, the new CXCR4 inhibitor IQS-01.01 has been preclinicaly evaluated in in vitro and in vivo models of DLBCL. It has been concluded that 1) inhibition of CXCR4 presents antitumor properties in DLBCL, 2) that IQS-01.01RS holds better pharmacological properties than the reference CXCR4 inhibitor, AMD3100 3) that treatment with IQS- 01.01RS reduces the levels of the oncogene MYC and 4) that the combinantion of IQS- 01.01RS with the BET-bromodomain inhibitor, CPI203, is synergistic in DLBCL. The results of this doctoral thesis unravel a cooperation between CXCR4 and MYC in DLBCL, and indicate that CXCR4 inhibition in combination with inhibition of MYC is a promising novel therapeutic approach in DLBCL. |
