SAN DIEGO, May 02, 2024 (GLOBE NEWSWIRE) -- Cardiff Oncology, Inc. (Nasdaq: CRDF), a clinical-stage biotechnology company leveraging PLK1 inhibition to develop novel therapies across a range of cancers, today announced financial results for the first quarter ended March 31, 2024, and provided a business update.
“During the start of 2024, we presented several important new data sets supporting our first-line RAS-mutated mCRC strategy and the broader opportunity for onvansertib,” said Mark Erlander, Ph.D., Chief Executive Officer of Cardiff Oncology. “The data from the ONSEMBLE trial replicated, in a second independent and randomized dataset, the bev naïve signal from our earlier Phase 1b/2 KRAS-mutated mCRC trial. And the Phase 1b data published in the peer-reviewed journal Clinical Cancer Research, and the additional data we presented in one of our five posters at AACR, further substantiated our lead program in RAS-mutated mCRC. The additional AACR posters also point toward new indications for onvansertib in RAS wild-type mCRC, small cell lung cancer and ovarian cancer. Looking ahead, we believe that our upcoming data readout from our first-line trial in RAS-mutated mCRC has the potential to serve as a key value inflection point for our company and revolutionize the treatment of RAS-mutated mCRC, an area with no new treatments approved in over two decades.”
Upcoming expected milestones
The Company has updated its expectation of the timing for an initial readout from the first-line RAS-mutated metastatic colorectal cancer (mCRC) randomized CRDF-004 trial to 2H 2024, based on the enrollment trends observed from active clinical trial sites.
Company highlights for the quarter ended March 31, 2024 and subsequent weeks include:
Presented updated data at AACR Annual Meeting 2024 that supports ongoing first-line RAS-mutated mCRC clinical study. In a poster titled “A Phase 1b/2 Clinical Study of Onvansertib in Combination with FOLFIRI/Bev Revealed a New Role of PLK1 in regulating the Hypoxia Pathway in KRAS-mutated mCRC,” updated clinical and preclinical data further supported the ongoing CRDF-004 Phase 2 trial of onvansertib + chemo/bev for the first-line treatment of RAS-mutated mCRC patients, who by definition are bev naïve.
In vitro, onvansertib inhibited activation of the hypoxia pathway through the regulation of transcription factor HIF1α and its downstream targets.
Bev naïve patients treated with onvansertib + FOLFIRI/bev demonstrated a significantly greater overall response rate [odds ratio=13.64, p
Announced first patient dosed for lead program in randomized first-line Phase 2 trial, CRDF-004, for patients with RAS-mutated mCRC. The trial, whose clinical execution is being conducted by our partner, Pfizer Ignite, is designed to confirm the dose of onvansertib for a subsequent registrational trial, and generate safety and efficacy data for onvansertib when added to standard of care (SoC) vs. SoC alone.
Interim topline results from CRDF-004 are expected in 2H 2024. Contingent upon the results, Cardiff Oncology will initiate a Phase 3, randomized trial, CRDF-005, with registrational intent.
Provided a clinical update on Phase 2 randomized second-line ONSEMBLE trial in mCRC. New clinical data from second-line randomized ONSEMBLE trial, that closed for enrollment in 2023, provide further evidence of onvansertib’s role in improving the efficacy of SoC (FOLFIRI+bev) therapy in bev naïve patients.
In the trial (n = 21), patients who were bev naïve and who received onvansertib in combination with SoC demonstrated an objective response rate (ORR) of 50% (2 of 4). No clinical responses were observed in bev naïve patients who received SoC alone (n = 3), or patients who were previously exposed to bev (n = 14).
The ONSEMBLE data serves as a second independent, randomized, prospective data set providing evidence of the strong efficacy signal in bev naïve patients.
Announced the publication of data from Phase 1b study in second line KRAS-mutated mCRC in the peer-reviewed journal Clinical Cancer Research. Findings from the Phase 1b portion of company's Phase 1b/2 study in second-line KRAS-mutated mCRC highlight the safety and promising efficacy of onvansertib in combination with SoC.
These peer-reviewed published data are part of the Phase 1b/2 data announced in August 2023 and informed the shift to investigation in first-line RAS-mutated mCRC (CRDF-004).
Presented three posters at AACR Annual Meeting 2024 in therapeutic areas outside of RAS-mutated mCRC In a poster titled “The PLK1 Inhibitor Onvansertib is Active as Monotherapy and in Combination with Cetuximab in RAS Wild-type mCRC Patient-derived Xenografts,” single agent onvansertib successfully induced tumor stasis or regression in 70% (14/20) of the RAS wild-type mCRC patient-derived xenograft (PDX) models tested which included both models sensitive to cetuximab (5/7, 71%) and resistant to cetuximab (9/13, 69%). Additionally, onvansertib in combination with cetuximab induced tumor stasis or regression in 90% (18/20) of the models tested. The antitumor activity of the combination was superior compared to monotherapy with either agent in both cetuximab sensitive and resistant models.
In a poster titled “The PLK1 Inhibitor, Onvansertib, Synergizes with Paclitaxel in Small Cell Lung Cancer (SCLC),” onvansertib in combination with paclitaxel was well-tolerated and demonstrated superior efficacy over monotherapies in cisplatin sensitive and resistant SCLC PDX models. These preclinical findings in SCLC and previous data generated in breast cancer suggest that onvansertib in combination with paclitaxel has the potential to become a highly promising combination strategy across multiple cancer indications.
In a poster titled “In vivo anti-tumor activity of onvansertib, a PLK1 inhibitor, combined with gemcitabine or carboplatin in platinum-resistant ovarian carcinoma patient-derived xenograft models,” onvansertib was synergistic in vitro in both combinations in an ovarian cancer cell line. Both combinations demonstrated antitumor activity in vivo in platinum-resistant ovarian cancer PDX models and was well tolerated. These data support the potential of onvansertib to improve SoC treatments for platinum-resistant ovarian cancer patients.
First Quarter 2024 Financial Results
Liquidity, cash burn, and cash runway
As of March 31, 2024, Cardiff Oncology had approximately $67.2 million in cash, cash equivalents, and short-term investments.
Net cash used in operating activities for the first quarter of 2024 was approximately $7.7 million, a decrease of approximately $1.0 million from $8.7 million for the same period in 2023.
Based on its current expectations and projections, the Company believes its current cash resources are sufficient to fund its operations into Q3 of 2025.
Operating results
Total operating expenses were approximately $11.1 million for the three months ended March 31, 2024, a decrease of $1.0 million from $12.1 million for the same period in 2023. The decrease in operating expenses was primarily due to a reduction in chemistry, manufacturing and controls costs compared to the prior period.
Conference Call and Webcast
Cardiff Oncology will host a corresponding conference call and live webcast at 4:30 p.m. ET/1:30 p.m. PT on May 2, 2024. Individuals interested in listening to the live conference call may do so by using the webcast link in the "Investors" section of the company's website at A webcast replay will be available in the investor relations section on the company's website following the completion of the call.
Cardiff Oncology is a clinical-stage biotechnology company leveraging PLK1 inhibition, a well-validated oncology drug target, to develop novel therapies across a range of cancers. The Company's lead asset is onvansertib, a PLK1 inhibitor being evaluated in combination with standard of care (SoC) therapeutics in clinical programs targeting indications such as RAS-mutated metastatic colorectal cancer (mCRC), as well as in investigator-initiated trials in metastatic pancreatic ductal adenocarcinoma (mPDAC), small cell lung cancer (SCLC) and triple negative breast cancer (TNBC). These programs and the Company's broader development strategy are designed to target tumor vulnerabilities in order to overcome treatment resistance and deliver superior clinical benefit compared to the SoC alone.
