Gilead Sciences acquires all outstanding shares of XinThera

“Gilead and XinThera share similar missions to discover new therapies to treat cancer and inflammatory diseases, which drive our determination to unlock the body’s ability to better respond to these diseases,” said Chris LeMasters, who served as XinThera CEO. “We are eager to join Gilead and together explore the potential of our precision medicines as critical components of the next generation of therapies targeting diseases with high unmet need.”

First-generation, dual PARP1/2 inhibitors have been shown to be highly efficacious in the treatment of patients with homologous recombination deficiency (HRD) tumors with BRCA-mutations such as breast, ovarian, prostate, and pancreatic cancers, but their use is limited due to hematological toxicities. PARP1 selective inhibitors have the potential to mitigate the hematological toxicities seen in first-generation, dual PARP1/2 inhibitors and enable combination with a wide variety of DNA-damaging agents, including systemic chemotherapy and targeted agents such as Trodelvy (sacituzumab govitecan-hziy).

The financial terms of the agreement were not disclosed. Beginning in the first quarter of 2022, consistent with recent industry communications from the U.S. Securities and Exchange Commission (SEC), Gilead no longer excludes acquired IPR&D expenses from its non-GAAP financial measures. "We expect the transaction with XinThera to reduce Gilead’s GAAP and non-GAAP 2023 EPS by approximately $0.12 - $0.15,"  the company stated.
