Strong cash financial position of approximately $105.3 million at December 31, 2022; projected runway into 2025

SAN DIEGO, March 2, 2023 /PRNewswire/ -- Cardiff Oncology, Inc. (Nasdaq: CRDF), a clinical-stage biotechnology company leveraging PLK1 inhibition, a well-validated oncology drug target, to develop novel therapies across a range of cancers, today announced financial results for the fourth quarter and full year ended December 31, 2022, and provided a business update.

"2022 was an important year for demonstrating the benefits onvansertib could bring to patients with KRAS-mutated mCRC, an area where no targeted therapies are currently approved. The results of our Phase 1b/2 trial in KRAS-mutated mCRC continue to show onvansertib plus standard-of-care was well-tolerated and outperformed historical control trials on key endpoints including the durability of response. Furthermore, we observed an unexpectedly high objective response rate and progression-free survival in the bevacizumab-naïve subgroup of patients which will be evaluated in the ongoing ONSEMBLE trial," said Mark Erlander, PhD, chief executive officer of Cardiff Oncology. "Looking forward, this will be an important year for advancing our ONSEMBLE randomized Phase 2 trial and generating additional safety and efficacy signals from our other company-sponsored and investigator-initiated clinical programs."

"As we build on these findings and accelerate onvansertib's clinical development, we will benefit greatly from the deep clinical expertise of our new CMO, Dr. Fairooz Kabbinavar, who served as the lead investigator for two practice-changing trials of bevacizumab combinations leading to the approval of bevacizumab in mCRC," continued Dr. Erlander. "We are confident we can fund our onvansertib clinical programs into 2025, and we believe our clinical data supports our approach to leveraging PLK1 inhibition to address current gaps in cancer therapies and make an important contribution to oncology patient care." 

Upcoming potential milestones

• mPDAC data readout from Phase 2 trial expected Q2/Q3 '23
• SCLC data readout from investigator-initiated (with UPMC) Phase 2 trial expected Q2/Q3 '23
• TNBC data readout from investigator-initiated (with Dana-Farber Cancer Institute) Phase 1b/2 trial expected Q4 '23/Q1 '24
• mCRC randomized data readout from Phase 2 ONSEMBLE trial expected Q3/Q4 '24

Company highlights for the year ended December 31, 2022, and subsequent weeks include:

• Strengthened management team with appointments of Fairooz Kabbinavar, MD, FACP, as CMO, Tod Smeal, Ph.D., as CSO and Charles Monahan, R.Ph., SVP, regulatory affairs. Overseeing the clinical development program for onvansertib, Dr. Kabbinavar brings world class capabilities and deep expertise in colorectal cancer and other solid tumor indications to Cardiff Oncology from his 30-plus years of experience across the academic and biotech/pharmaceutical sectors. During his time as an academic oncologist, he was the lead investigator on two practice-changing clinical trials of bevacizumab (Avastin®) combinations leading to approval of bevacizumab in mCRC^1,2. As principal medical director of Genentech's immuno-oncology program, he led the clinical development of atezolizumab (TECENTRIQ®) in extensive stage small cell lung cancer and oversaw the filing of the supplemental biologics license application that led to the drug's FDA approval. Dr. Smeal has over 20 years of industry experience developing targeted therapies and previously served as CSO of Cancer Biology at Eli Lilly and Company, and director of the Oncology Research Unit of Pfizer. Mr. Monahan is a registered pharmacist with over 20 years of regulatory experience developing drugs and biologics for oncology, infectious diseases, and ocular indications. Prior to joining Cardiff Oncology, he most recently served as the global head of regulatory affairs for Erytech PharmaSA.
  
  
• Announced ONSEMBLE, a Phase 2, open-label, randomized trial for second line treatment of KRAS/NRAS-mutated mCRC, as the next step in our mCRC clinical development program. We designed the ONSEMBLE trial to corroborate the robust efficacy signal observed in the Phase 1b/2 trial of onvansertib plus standard-of-care (SoC) FOLFIRI/bevacizumab in second-line KRAS-mutated mCRC, demonstrate onvansertib's contribution above SoC alone and confirm the optimal dose.
  
  
• Presented robust data from the Phase 1b/2 trial of onvansertib plus FOLFIRI/bevacizumab in second line KRAS-mutated mCRC on a company webcast in September 2022. Objective response rate (ORR) across all evaluable patients was 35% (n=48) as compared to an ORR of 5-13% observed historically, and the median duration of response (mDoR) across all evaluable patients was 11.7 months. Median progression-free survival (mPFS) was 9.3 months across all evaluable patients, as compared to mPFS of ~4.5 – 5.7 months observed historically in combination trials that included the standard-of-care FOLFIRI with bevacizumab.^3-6
  
  
• Completed subgroup analysis from Phase 1b/2 mCRC trial shows improved ORR and mPFS in bevacizumab-naïve patients. A subgroup analysis from the ongoing Phase 1b/2 clinical trial of onvansertib plus FOLFIRI/bevacizumab in second line KRAS-mutated mCRC showed an ORR of 69% and mPFS of 13.5 months in bevacizumab naïve patients (n=13). These data compare favorably to historical control trials in mCRC, which show an ORR of approximately 25% and a mPFS of approximately 6.9 months in bevacizumab naïve patients^6-11.
  
  
• Data presented at the ESMO Congress 2022 suggest combining onvansertib with irinotecan (a component of FOLFIRI) overcomes irinotecan-resistance in RAS-mutated mCRC. Findings from our Expanded Access Program (EAP) of onvansertib in KRAS-mutated mCRC as well as preclinical data from patient-derived xenograft (PDX) models of irinotecan-resistant, RAS-mutated mCRC were featured in a poster at the ESMO Congress 2022 showing EAP patients with prior irinotecan treatment (43 of 51) showed clinical benefit following treatment and the combination of onvansertib and irinotecan showed significantly greater anti-tumor activity compared to onvansertib monotherapy in 5 of 6 tested PDX models of irinotecan-resistant, RAS-mutated mCRC.
  
  
• Presented preliminary data from our clinical trial in Metastatic Pancreatic Ductal Adenocarcinoma (mPDAC). Preliminary data from five evaluable patients in an ongoing open-label Phase 2 trial of onvansertib in combination with nanoliposomal irinotecan and 5-FU in second-line metastatic PDAC provide early signal of efficacy and compare favorably to historical control trials.
  
  
• Enrolled first patients in two investigator-initiated trials in triple negative breast cancer (TNBC) and small cell lung cancer (SCLC).

Full Year 2022 Financial Results:

Liquidity, cash burn, and cash runway

As of December 31, 2022, Cardiff Oncology had approximately $105.3 million in cash, cash equivalents, and short-term investments.

Net cash used in operating activities for the full year 2022 was approximately $33.8 million, an increase of approximately $10.8 million from $23.0 million for the same period in 2021.

Based on its current expectations and projections, the Company believes its current cash resources are sufficient to fund its operations into 2025.

Operating results

Total operating expenses were approximately $40.3 million for the full year ended December 31, 2022, an increase of $11.1 million from $29.2 million for the same period in 2021. The increase in operating expenses was primarily due to advancing the development of onvansertib through chemistry, manufacturing, and controls (CMC) activities, pharmacology and other development programs, salaries and staff costs primarily due to increased headcount, stock-based compensation for additional grants to employees and higher facility costs for insurance and the amending of our operation lease.
