Cardiff Oncology, Inc. is an oncology therapeutics company, which engages in the development of drugs that target mitosis for the treatment of various types of cancer. The company is headquartered in San Diego, California and currently employs 32 full-time employees. The company went IPO on 2004-07-27. The company is leveraging PLK1 inhibition, a well-validated oncology drug target, to develop novel therapies across a range of cancers with unmet medical need. The company is focused on clinical programs in indications, such as RAS-mutated metastatic colorectal cancer (mCRC), and in investigator-initiated trials in metastatic pancreatic ductal adenocarcinoma (mPDAC), small cell lung cancer (SCLC), and triple negative breast cancer (TNBC). Its lead drug candidate, Onvansertib, is an oral, small-molecule drug candidate that is highly specific for PLK1 inhibition with a 24-hour half-life. The company has other ongoing and planned clinical trials of onvansertib: one trial (CRDF-004) in first-line treatment in patients with RAS-mutated mCRC, and investigator-initiated trials in first-line mPDAC, relapsed SCLC and unresectable locally advanced or metastatic TNBC.
