Debiopharm Ignites Oncology Innovation With Clinical and Translational Data on Debio 0123 at the 2025 ASCO Annual Meeting in Chicago
Debiopharm (www.debiopharm.com), a privately-owned, Swiss-based biopharmaceutical company aiming to establish tomorrow’s standard-of-care to cure cancer and infectious diseases, today unveiled its upcoming contributions to the 2025 Annual American Society of Clinical Oncology (ASCO) Meeting in Chicago, Illinois.
The contributions feature three clinical poster presentations and one translational research abstract publication, highlighting Debio 0123’s potential across solid tumors. Among them is new data from the Debio 0123-SCLC-104 trial in small-cell lung cancer, offering insights into the candidate’s therapeutic potential in this difficult-to-treat disease. A Trial in Progress (TiP) poster from the investigator-initiated MedSir study—co-authored by Debiopharm—will present the design and methodology of the study investigating the combination of Debio 0123 with Trodelvy® in breast cancer patients. In parallel, a separate TiP poster for the Debio 0123-102 monotherapy study will outline the framework and objectives of the ongoing dose expansion phase.
“Presenting our latest data on Debio 0123 at ASCO 2025 is a proud milestone for our team,” said Angela Zubel, Chief Development Officer at Debiopharm. “This research highlights the promise of WEE1 inhibition as a precision strategy to target the vulnerabilities of aggressive cancers. Our goal is to push the boundaries of innovation to bring transformative therapies to patients who urgently need new options.”

About DNA-Damage Repair (DDR)
When cells have damaged DNA, they need to undergo a repair process called DDR to be able to survive. Cancer cells rely heavily on DDR as they divide and grow uncontrollably. Inhibition of DDR, particularly in combination with other anticancer agents, prevents cancer cells from repairing their DNA, which ultimately activates a self-destruction program in cancer cells. DDR inhibitors such as Debiopharm's WEE1 inhibitor Debio 0123 are being tested in clinical and preclinical studies.
Debiopharm's commitment to patients
Debiopharm aims to develop innovative therapies that target high unmet medical needs primarily in oncology and bacterial infections. Bridging the gap between disruptive discovery products and real-world patient reach, we identify high-potential compounds and technologies for in-licensing, clinically demonstrate their safety and efficacy, and then hand stewardship to large pharmaceutical commercialization partners to maximize patient access globally.

Parse Biosciences and Codebreaker Labs Partner to Apply Whole Transcriptome Single Cell Profiling and Causal Genomics at Scale19.12.2025 14:00:00 CET | Press Release
Parse Biosciences, the leading provider of scalable and accessible single cell sequencing solutions, today announced a collaboration with Codebreaker Labs to develop and validate a breakthrough platform capable of testing thousands of genetic variants in parallel and measuring their effects at single cell resolution. By combining Codebreaker’s synthetic biology platform and variant engineering capabilities with the scale and accessibility of Parse’s Evercode™ technology, the collaboration aims to generate the causal data increasingly sought by AI developers, drug discovery teams, and clinical researchers. Today’s genomic studies rely heavily on observational data, or variants that appear in large populations. But rare and private variants, often only seen in one individual or family, are nearly impossible to study this way because too few carriers of the variant exist to draw statistically meaningful conclusions. As a result, even the most advanced models trained on observational datas
