Cardiff Oncology and Nerviano Medical Sciences Amend their 2017 Exclusive License Agreement

SAN DIEGO and NERVIANO, Italy, Sept. 14, 2026 (GLOBE NEWSWIRE) -- Cardiff Oncology, Inc. (NASDAQ: CRDF) ("Cardiff") and Nerviano Medical Sciences S.r.l. ("NMS") today announced that they have reached a settlement and amended their 2017 Exclusive License Agreement, resolving all outstanding disputes between the two companies related to the global rights for onvansertib, Cardiff's lead PLK1 inhibitor drug candidate, and establishing an expanded collaborative framework to support onvansertib's continued clinical development.

Cardiff and NMS have agreed to a full and mutual release of all claims asserted in the litigation pending in the U.S. District Court for the Southern District of California. Cardiff and NMS plan to jointly request dismissal of all claims with prejudice.

“This Amendment strengthens our long-term rights to onvansertib as a promising treatment for cancer, beginning with first-line RAS-mutated metastatic colorectal cancer,” said Mani Mohindru, PhD, President and Chief Executive Officer of Cardiff Oncology. “We are pleased to be entering into this agreement with NMS, which reflects our shared commitment to bringing onvansertib to patients with high unmet need.”

“We look forward to working with Cardiff to advance onvansertib into a global Phase 3 study in first-line RAS-mutated metastatic colorectal cancer and to bring this therapy to patients,” said Hugues Dolgos, PharmD, Chief Executive Officer of NMS Group S.r.l.

The Parties clarified and expanded on the royalty structure in the License Agreement. The agreement also includes development objectives related to Cardiff’s upcoming Phase 3 program, as well as rights for NMS to appoint a Board observer and join Cardiff’s Scientific Advisory Board.

About Onvansertib Onvansertib is a highly specific, oral PLK1 inhibitor advancing toward a registrational trial in first-line RAS-mutated mCRC. In a randomized Phase 2 trial, onvansertib in combination with FOLFIRI/bevacizumab (first-line standard-of-care) demonstrated dose-dependent improvements in overall response rate and progression-free survival compared to standard-of-care alone, building on findings from a prior Phase 2 trial in second-line RAS-mutated mCRC. Based on these results, the Company has selected the 30 mg dose of onvansertib in combination with FOLFIRI/bevacizumab for advancement into a registrational trial in first-line patients with RAS-mutated mCRC.
