SAN FRANCISCO, Calif., July 19, 2023— Circle Pharma, a biopharmaceutical company advancing the discovery and development of intrinsically cell-permeable macrocycles, announced today the selection of CID-078 for its first clinical development program. CID-078 is the first-and-only-in-class dual inhibitor of Cyclins A and B, which play essential roles in regulating cell cycle progression. Inhibiting Cyclins A and B selectively induces synthetic lethality in certain cancers exhibiting cell cycle dysregulation while sparing healthy cells.
Circle Pharma recently presented pre-clinical data for its dual Cyclin A/B inhibitors at this year’s American Association for Cancer Research (AACR) Annual Meeting. The data demonstrated activity across a wide range of human tumor cell lines including tumor regression in xenograft models of small cell lung carcinoma (SCLC) and ovarian cancer. SCLC has a five-year survival rate of 3.5%, and its treatment has seen minimal progress in the last 30 years. Ovarian cancer patients commonly face poor outcomes and resistance to the current standard of care. In advance of human clinical trials for CID-078, further preclinical studies using patient-derived models (PDX) are underway in breast cancer (including triple negative breast cancer), non-small cell lung cancer, gastric cancer, pancreatic cancer, and other tumor types.
“The selection of CID-078 represents a major milestone for our team; we are excited to advance this molecule into clinical development and to realize its potential to bring new hope for the many cancer patients who currently have woefully inadequate treatment options,” said David Earp, J.D., Ph.D., President and Chief Executive Officer of Circle Pharma. “This achievement is also a reflection of the capabilities of our macrocycle discovery platform as the cyclins have until now been considered undruggable.”
ABOUT CID-078
CID-078 is an orally bioavailable macrocycle with dual cyclin A and B inhibitory activity that drives synthetic lethality in multiple tumor types. In biochemical and cellular studies, CID-078 has been shown to potently and selectively disrupt the protein-protein interaction between Cyclins A and B and their key substrates, including E2F (a substrate of Cyclin A) and Myt1 (a substrate of Cyclin B). Preclinical studies have demonstrated the ability of CID-078 to cause pronounced tumor regression in multiple xenograft models. Circle Pharma plans to file an investigational new drug (IND) application with the U.S. Food and Drug Administration (FDA) for CID-078 and initiate clinical development in 2024.
ABOUT CIRCLE PHARMA’S MACROCYCLE THERAPEUTICS
Macrocycles are a class of molecules that have properties outside of the conventional “rule of five” for oral small molecule drugs. They have the potential to address important therapeutic targets, such as protein-protein interactions, that are refractory to other drug classes, but their larger size and chemical complexity present additional challenges to drug developers. Circle Pharma’s proprietary technology platform, MXMO™, introduces a highly differentiated ability to develop precision macrocycle therapeutics that are passively cell-permeable and orally bioavailable. Circle Pharma’s macrocycles also have desirable pharmacokinetics, are exquisitely selective, and can be directed to both intra- and extra-cellular therapeutic targets.

SAN FRANCISCO, Calif.–(BUSINESS WIRE)–Circle Pharma announced today that two poster presentations at the American Association for Cancer Research (AACR) Annual Meeting held April 14-19, in Orlando, Florida, highlight promising pre-clinical data of its first-in-class orally bioavailable macrocyclic cyclin A/B inhibitors targeting intractable cancers. Circle expects to advance its cyclin A/B inhibitor program into IND-enabling studies later this year and subsequently into clinical development for testing in a range of cancer types, including SCLC.
The data presented by Circle Pharma shows activity across a wide range of human tumor cell lines and tumor regression in xenograft models of small cell lung carcinoma (SCLC) and ovarian cancer. Pre-clinical development of orally bioavailable macrocycles with dual cyclin A and B inhibitory activity drive synthetic lethality in multiple tumor types. The compounds are shown to be well-tolerated in mice with no observed body weight loss, neutropenia, or depletion of bone marrow across all dose regimens. In vitro studies showed that target engagement in cells leads to displacement of E2F1 from Cyclin A:CDK2 and Myt1 from Cyclin B:CDK1, and the compounds induce DNA damage, G2/M arrest, and apoptosis. The presentation further showed that sensitivity in SCLC cell lines is correlated with RB dysfunction and E2F1 target gene expression.
In addition, studies conducted by the laboratory of Matthew Oser at Dana Farber Cancer Institute (DFCI) validate that cyclin A/B inhibitors induce mitotic arrest and apoptosis in SCLC cell lines. The researchers deployed a genome wide CRISPR/Cas9 positive selection screen to identify that activation of the mitotic spindle assembly checkpoint (SAC) complex by the kinase MSP1 is a dominant mechanism for selective cancer cell killing by the cyclin A/B inhibitors. Dr. Oser’s laboratory at DFCI was sponsored by Circle Pharma.
