Morphic Therapeutic Presents Preclinical Data from αvβ8 Integrin Program at American Association for Cancer Research (AACR) Annual Meeting

First data from oral αvβ8 program demonstrate potent anti-tumor response through TGFβ pathway

Combination with checkpoint inhibitor showed efficacy in checkpoint-resistant models of breast cancer and induced a lasting anti-tumor effect

WALTHAM, Mass., April 12, 2021 (GLOBE NEWSWIRE) -- Morphic Therapeutic (Nasdaq: MORF), a biopharmaceutical company developing a new generation of oral integrin therapies for the treatment of serious chronic diseases, today announced the presentation of the first preclinical data from its αvβ8 integrin program at the 2021 American Association for Cancer Research (AACR) Annual Virtual Meeting. These preclinical data show that an orally administered αvβ8 integrin inhibitor is a potent modulator of anti-tumor immune response in checkpoint-inhibitor resistant tumors and support development of this new therapeutic approach. αvβ8 is known to mediate the activation of tumor growth factor beta (TGFβ1/3). Morphic is developing oral small molecule inhibitors of the αvβ8 integrin which is expressed on cell types central to immune response and is a major contributor to tolerance and suppression of anti-tumor immunity.

“These new data, in multiple well characterized preclinical models, support αvβ8 inhibition as a potential mechanism for the modulating response tumors that are resistant to immune checkpoint therapy. We are using Morphic’s proprietary integrin therapeutic design platform, MInT, to develop candidates intended to enhance outcomes in checkpoint inhibitor regimens by modulating tumor response-associated integrins,” commented Bruce Rogers, Ph.D., chief scientific officer at Morphic Therapeutic. “We believe the opportunity to convert checkpoint-resistant or “cold” tumors into “hot” tumors that are responsive to checkpoint therapy, is a promising and highly compelling opportunity in immuno-oncology.”

The research demonstrates that Morphic’s small molecule inhibitor in combination with anti-PD-1 drives efficacy across mouse models of treatment-resistant breast cancer including the EMT6 and PyMT syngeneic breast cancer models. Furthermore, the anti-tumor activity was seen to be mediated through adaptive immunity and be dependent on CD8 T cells. The examination of immune cell gene signatures on immune cell populations within tumor and lymphoid organs provided evidence for a lasting state of reduced tumor tolerance in these models.
