Cardiff Oncology Announces Upcoming Poster Presentations at the AACR Annual Meeting

SAN DIEGO, March 8, 2022 /PRNewswire/ -- Cardiff Oncology, Inc. (Nasdaq: CRDF), a clinical-stage biotechnology company leveraging PLK1 inhibition to develop novel therapies across a range of cancers, today announced the publication of two abstracts that have been accepted for poster presentations at the American Association for Cancer Research (AACR) Annual Meeting, which is taking place both virtually and in-person at the Ernest N. Morial Convention Center in New Orleans, Louisiana from April 8-13, 2022.

The full texts of the published abstracts can be found on the AACR Annual Meeting website. Details on the corresponding posters are shown below.

Poster Title:

Biomarkers of response to abiraterone and the polo-like kinase 1 (PLK1)
inhibitor onvansertib in metastatic castration resistant prostate cancer
(mCRPC) patients

Session Title:

Biomarkers Predictive of Therapeutic Benefit 1

Session Date:

April 11, 2022

Session Start Time:

9:00 AM CT


Poster Section 30

This abstract describes genomic and transcriptomic analyses from the ongoing Phase 2 trial of onvansertib in combination with Zytiga® (abiraterone)/prednisone in mCRPC patients with early abiraterone resistance. Collectively, these analyses suggest that alterations in PTEN and MTOR, two key genes of the PI3K signaling pathway, are potential biomarkers for sensitivity to onvansertib-abiraterone combination therapy in mCRPC patients with early abiraterone-resistance.

Poster Title:

Combining PARP inhibition with the polo-like kinase 1 (PLK1)
inhibitor onvansertib overcomes PARP inhibitor resistance

Session Title:

Drug Resistance and Reversal of Resistance

Session Date:

April 12, 2022

Session Start Time:

1:30 PM CT


Poster Section 22

This abstract includes preclinical data that demonstrate the potent anti-tumor activity of onvansertib combined with the PARP inhibitor olaparib in olaparib-resistant ovarian cancer models. Additional preclinical studies are ongoing to further assess the potential of the onvansertib-olaparib combination in models of ovarian, prostate, pancreatic and breast cancer.

About Cardiff Oncology, Inc.
Cardiff Oncology is a clinical-stage biotechnology company leveraging PLK1 inhibition to develop novel therapies across a range of cancers. Our lead asset is the third generation PLK1 inhibitor onvansertib, which we are evaluating in combination with standard-of-care (SOC) therapeutics in clinical programs targeting indications such as KRAS-mutated metastatic colorectal cancer, metastatic pancreatic ductal adenocarcinoma, and metastatic castrate-resistant prostate cancer. These programs and our broader development strategy are designed to target tumor vulnerabilities in order to overcome treatment resistance and deliver superior clinical benefit compared to the SOC.
